## 🎯 Was Sie damit erreichen
### Vor der Integration
```
Scraper (standard)
└─ Ein einzelner Browser ohne IP-Rotation
└─ Alle Requests von gleicher IP
└─ Risiko: IP-Block durch Zielwebsite
```
### Nach der Integration
```
Scraper mit ProtonVPN
├─ Session 1 (US, IP: 1.2.3.4)
│ ├─ Task 1, 2, 3, 4, 5 (gleiche IP)
│ └─ Perfekt für: Zusammenhängende Data
│
├─ Session 2 (UK, IP: 5.6.7.8)
│ ├─ Task 6, 7, 8, 9, 10 (gleiche IP)
│ └─ Perfekt für: Mehrstufige Extraktion
│
└─ Session 3 (JP, IP: 9.10.11.12)
├─ Task 11, 12, 13, 14, 15 (gleiche IP)
└─ Perfekt für: Diverse geografische Daten
```
### Ergebnisse
- ✅ **IP-Rotation:** Automatisch zwischen Sessions
- ✅ **Flexibel:** Konfigurierbar wie viele Tasks pro IP
- ✅ **Zuverlässig:** Automatische VPN-Verbindung & Überprüfung
- ✅ **Monitörbar:** Strukturiertes Logging aller Operationen
- ✅ **Wartbar:** Sauberer, modularer Code

---
## 💻 Technische Highlights
### Modular & Flexibel
```rust
// Easy to enable/disable
ENABLE_VPN_ROTATION=false // Alle VPN-Komponenten deaktiviert
// Easy to configure
VPN_SERVERS=US,UK,JP // Beliebig viele Server
TASKS_PER_VPN_SESSION=10 // Flexible Rotation
```
### Production-Ready Code
- Fehlerbehandlung mit aussagekräftigen Kontexten
- Asynchrone, non-blocking Operations
- Structured Logging für Debugging
- Unit Tests für kritische Funktionen
### Zero Additional Dependencies
- Nutzt bereits vorhandene Crates: `tokio`, `fantoccini`, `serde`, `anyhow`, `tracing`
- Keine neuen, externen Abhängigkeiten erforderlich
---
## 🧪 Wie man testen kann
### Ohne VPN (Baseline)
```bash
ENABLE_VPN_ROTATION=false MAX_PARALLEL_TASKS=1 cargo run
# Schnell, keine VPN-Logs
```
### Mit VPN, langsam (zum Debuggen)
```bash
ENABLE_VPN_ROTATION=true VPN_SERVERS=US TASKS_PER_VPN_SESSION=5 \
MAX_PARALLEL_TASKS=1 RUST_LOG=debug cargo run
```
### Mit VPN, parallel (Production)
```bash
ENABLE_VPN_ROTATION=true VPN_SERVERS=US,UK,JP \
TASKS_PER_VPN_SESSION=20 MAX_PARALLEL_TASKS=3 cargo run
```

## 🔑 Wichtige Konzepte
### Session
Eine Periode, in der Browser-Traffic durch einen ProtonVPN-Server geleitet wird (gleiche IP).
### Task-Counter
Zählt Aufgaben pro Session. Nach Erreichen des Limits: Neue Session mit neuer IP.
### Extension-Automater
Automatisiert die ProtonVPN Chrome-Extension UI für:
- Verbindung trennen/verbinden
- Server auswählen
- IP-Überprüfung
### VpnIntegration
High-Level API für einfache Verwendung in Ihren Modulen.

## 📊 Erfolgs-Metriken
Nach erfolgreicher Integration sollten Sie sehen:
✅ **Logs wie diese:**
```
✓ Created new VPN session: session_US_1702123456789
🔗 Connecting to ProtonVPN server: US
✓ Successfully connected to US after 3500 ms
📍 Current external IP: 192.0.2.42
✓ Task 1/100 completed in session session_US_1702123456789
```
✅ **Config funktioniert:**
```
ENABLE_VPN_ROTATION=true
VPN_SERVERS=US,UK,JP
TASKS_PER_VPN_SESSION=10
```
✅ **Verschiedene IPs pro Session:**
```
Session 1 (US): IP 192.0.2.1 (Tasks 1-10)
Session 2 (UK): IP 198.51.100.1 (Tasks 11-20)
Session 3 (JP): IP 203.0.113.1 (Tasks 21-30)
```
---
## ⚠️ Wichtige Hinweise
1. **Extension-UI kann sich ändern**
- Prüfen Sie XPath-Selektoren nach Extension-Updates
- Siehe: TROUBLESHOOTING_DE.md
2. **VPN braucht Zeit**
- 2-3 Sekunden zum Disconnect/Connect
- Timeouts in Code berücksichtigen
3. **Browser muss sichtbar sein**
- Headless-Mode funktioniert teilweise nicht
- Für Tests: `--headless=false` verwenden
4. **IP-Rotation nicht garantiert**
- ProtonVPN mit Load-Balancing kann ähnliche IPs haben
- Aber typischerweise unterschiedlich genug für Scraping

## 🔑 Hauptkomponenten
### 1. VpnSessionManager (`vpn_session.rs`)
Verwaltet VPN-Sessions mit Server-Rotation:
- Server-Liste durchlaufen (round-robin)
- Task-Counter pro Session
- Automatische Rotation wenn Limit erreicht
```rust
let manager = VpnSessionManager::new(
vec!["US", "UK", "JP"],
5 // 5 Tasks pro Session
);
manager.create_new_session().await?;
manager.increment_task_count().await;
if manager.should_rotate().await {
// Neue Session erstellen
}
```
### 2. ProtonVpnAutomater (`protonvpn_extension.rs`)
Automatisiert die ProtonVPN-Extension-UI:
- Verbindung trennen
- Mit Server verbinden
- VPN-Status überprüfen
- IP-Adresse abrufen
```rust
let automater = ProtonVpnAutomater::new("extension-id");
automater.connect_to_server(&client, "US").await?;
let ip = automater.get_current_ip(&client).await?;
```
### 3. VpnIntegration (`vpn_integration.rs`)
Vereinfachte High-Level API für Module:
- Initialisierung aus Config
- Session-Rotation prüfen & durchführen
- Task-Counter verwalten
```rust
let vpn = VpnIntegration::from_config(&config)?;
if vpn.check_and_rotate_if_needed().await? {
// Neue Session erstellt
}
vpn.increment_task().await;
```
---
## 📝 Integrations-Anleitung
### Schritt 1: VpnIntegration in main.rs
```rust
use scraper::vpn_integration::VpnIntegration;
#[tokio::main]
async fn main() -> Result<()> {
let config = Config::load()?;
let vpn = VpnIntegration::from_config(&config)?;
let pool = Arc::new(ChromeDriverPool::new(config.max_parallel_tasks).await?);
// Initiale Session
if vpn.enabled {
vpn.initialize_session().await?;
}
// Updates mit VPN
economic::run_full_update(&config, &pool, &vpn).await?;
corporate::run_full_update(&config, &pool, &vpn).await?;
Ok(())
}
```
### Schritt 2: Economic/Corporate Module aktualisieren
```rust
// src/economic/mod.rs
pub async fn run_full_update(
config: &Config,
pool: &Arc<ChromeDriverPool>,
vpn: &scraper::vpn_integration::VpnIntegration,
) -> Result<()> {
for task in tasks {
if vpn.check_and_rotate_if_needed().await? {
tokio::time::sleep(Duration::from_secs(2)).await;
}
// Task ausführen
vpn.increment_task().await;
}
Ok(())
}
```
---
## 🧪 Testing
### Test 1: Ohne VPN (Baseline)
```bash
ENABLE_VPN_ROTATION=false MAX_PARALLEL_TASKS=1 cargo run
```
### Test 2: Mit VPN, langsam
```bash
ENABLE_VPN_ROTATION=true VPN_SERVERS=US MAX_PARALLEL_TASKS=1 TASKS_PER_VPN_SESSION=5 RUST_LOG=debug cargo run
```
### Test 3: Mit VPN, parallel
```bash
ENABLE_VPN_ROTATION=true VPN_SERVERS=US,UK,JP MAX_PARALLEL_TASKS=3 TASKS_PER_VPN_SESSION=10 cargo run
```
### Unit Tests
```bash
cargo test scraper::vpn_session
cargo test scraper::protonvpn_extension
```

## ⚙️ Konfigurationsoptionen
| Var | Typ | Standard | Beschreibung |
|-----|-----|----------|-------------|
| `ENABLE_VPN_ROTATION` | bool | `false` | VPN aktivieren? |
| `VPN_SERVERS` | String | `` | Server-Liste |
| `TASKS_PER_VPN_SESSION` | usize | `0` | Tasks vor Rotation (0=zwischen Phasen) |
| `PROTONVPN_EXTENSION_ID` | String | `ghmbeldphafepmbegfdlkpapadhbakde` | Extension ID |
| `MAX_PARALLEL_TASKS` | usize | `10` | ChromeDriver-Instanzen |
---
## 🐛 Fehlerbehandlung
Alle Module verwenden `anyhow::Result<T>`:
- Automatische Error-Propagation mit `?`
- Detaillierte Kontextinformation mit `.context()`
- Strukturiertes Logging mit `tracing`
```rust
client.goto(&url)
.await
.context("Failed to navigate")?;
```
---
## 🔍 Monitoring & Logging
```bash
# Info-Level
RUST_LOG=info cargo run
# Debug-Level (für Troubleshooting)
RUST_LOG=debug cargo run
# Nur VPN-Logs
RUST_LOG=scraper::protonvpn_extension=debug cargo run
# Speichern in Datei
RUST_LOG=info cargo run > app.log 2>&1
```
**Beispiel-Log-Ausgabe:**
```
✓ Created new VPN session: session_US_1702123456789 with server: US
🔗 Connecting to ProtonVPN server: US
✓ Successfully connected to US after 5500 ms
📍 Checking current external IP address
Current external IP: 192.0.2.42
✓ Task 1/100 completed in session session_US_1702123456789

## 🚨 Wichtige Hinweise
⚠️ **Extension UI-Selektoren können veränderlich sein**
- Prüfen Sie regelmäßig mit Chrome DevTools (F12)
- Aktualisieren Sie XPath bei Extension-Updates
⚠️ **VPN-Verbindung braucht Zeit**
- 2-3 Sekunden zum Trennen/Verbinden einplanen
- Timeouts in Code berücksichtigen
⚠️ **Browser muss für UI-Automatisierung sichtbar sein**
- Headless-Mode funktioniert teilweise nicht
- Bei Tests: `--headless=false` verwenden
⚠️ **IP-Rotation ist nicht garantiert**
- ProtonVPN-Server mit Load-Balancing können ähnliche IPs haben
- Aber typischerweise unterschiedlich genug für Website-Scraping
---
## 🎯 Nächste Schritte
1. **Sofort:**
- `.env` vorbereiten
- ProtonVPN Extension installieren
- `cargo build` testen
2. **Diese Woche:**
- Integration in Economic Module
- Integration in Corporate Module
- Performance-Tests mit verschiedenen Konfigurationen
3. **Später:**
- Monitoring Dashboard für VPN-Sessions
- Analytics für IP-Rotation
- Alternative Proxy-Support (optional)

# ProtonVPN-Integration für WebScraper: Quick-Start Guide
## 🚀 Schnelleinstieg (5 Minuten)
### 1. Konfiguration vorbereiten
```bash
# Copy .env.example zu .env
cp .env.example .env
# Öffnen Sie .env und aktivieren Sie VPN:
# ENABLE_VPN_ROTATION=true
# VPN_SERVERS=US-Free#1,UK-Free#1,JP-Free#1
# TASKS_PER_VPN_SESSION=5
```
### 2. ProtonVPN-Extension installieren
```bash
# A. Automatisch (empfohlen):
# Chrome öffnet die Extension automatisch beim ersten Browser-Start
# B. Manuell:
# 1. Chrome öffnen
# 2. chrome://extensions/ öffnen
# 3. "ProtonVPN by Proton Technologies AG" suchen
# 4. Installieren & Anmelden mit ProtonVPN-Account
```
### 3. Extension-ID überprüfen
```bash
# 1. Chrome → chrome://extensions/
# 2. ProtonVPN Details klicken
# 3. Extension ID kopieren
# 4. In .env eintragen:
# PROTONVPN_EXTENSION_ID=ghmbeldphafepmbegfdlkpapadhbakde
```
### 4. Cargo.toml überprüfen
```toml
[dependencies]
fantoccini = { version = "0.20", features = ["rustls-tls"] }
tokio = { version = "1.38", features = ["full"] }
tracing = "0.1"
tracing-subscriber = { version = "0.3", features = ["fmt", "env-filter"] }
```
### 5. Projekt kompilieren & testen
```bash
# Kompilierung
cargo build --release
# Mit Logging starten
RUST_LOG=info cargo run
# Mit Debug-Logging:
RUST_LOG=debug cargo run
```

---
## 🧪 Testing-Szenarios
### Test 1: Ohne VPN (Baseline)
```bash
ENABLE_VPN_ROTATION=false MAX_PARALLEL_TASKS=1 RUST_LOG=info cargo run
```
**Erwartung:** Schnell, stabil, keine VPN-Logs
### Test 2: Mit VPN, ein Server
```bash
ENABLE_VPN_ROTATION=true VPN_SERVERS=US TASKS_PER_VPN_SESSION=10 MAX_PARALLEL_TASKS=1 RUST_LOG=info cargo run
```
**Erwartung:** Eine Session den ganzen Tag, gleiche IP
### Test 3: Mit VPN, Server-Rotation
```bash
ENABLE_VPN_ROTATION=true VPN_SERVERS=US,UK,JP TASKS_PER_VPN_SESSION=5 MAX_PARALLEL_TASKS=1 RUST_LOG=debug cargo run
```
**Erwartung:** Neue Session alle 5 Tasks, wechselnde IPs
### Test 4: Mit VPN, Parallel
```bash
ENABLE_VPN_ROTATION=true VPN_SERVERS=US,UK,JP MAX_PARALLEL_TASKS=3 TASKS_PER_VPN_SESSION=20 RUST_LOG=info cargo run
```
**Erwartung:** 3 parallele Tasks, nach 20 Tasks pro Instanz Rotation

## 🔍 Was wird wo integriert?
### `src/config.rs`
```rust
// Neue Fields:
pub enable_vpn_rotation: bool,
pub vpn_servers: String,
pub tasks_per_vpn_session: usize,
pub protonvpn_extension_id: String,
// Neue Methode:
pub fn get_vpn_servers(&self) -> Vec<String>
```
### `src/scraper/mod.rs`
```rust
pub mod vpn_session;
pub mod protonvpn_extension;
pub mod vpn_integration;
```
### `src/main.rs` (optional, aber empfohlen)
```rust
let vpn_integration = VpnIntegration::from_config(&config)?;
if vpn_integration.enabled {
vpn_integration.initialize_session().await?;
}
// In Tasks:
vpn_integration.check_and_rotate_if_needed().await?;
vpn_integration.increment_task().await;
```

## 🐛 Häufigste Fehler & Lösungen
| Fehler | Lösung |
|--------|--------|
| `Failed to navigate to chrome-extension://...` | Extension nicht installiert oder falsche ID |
| `Button 'connect' not found` | Extension-Version hat sich geändert, Selektoren aktualisieren (TROUBLESHOOTING_DE.md) |
| `Failed to extract IP from page` | Alternative IP-Check-Service verwenden (icanhazip.com, ifconfig.me) |
| `Semaphore closed` | ChromeDriver-Pool zu klein oder zu viele parallele Tasks |
| `Timeout connecting to server` | Netzwerk-Latenz oder ProtonVPN-Server überlastet, Timeout erhöhen |

## 🎯 Nächste Schritte
1. **Integration in Economic Module:**
```rust
// src/economic/mod.rs
use scraper::vpn_integration::VpnIntegration;
pub async fn run_full_update_with_vpn(
config: &Config,
pool: &Arc<ChromeDriverPool>,
vpn: &VpnIntegration,
) -> Result<()> {
// für jeden Task:
if vpn.check_and_rotate_if_needed().await? {
sleep(Duration::from_secs(2)).await;
}
// ... task execution ...
vpn.increment_task().await;
}
```
2. **Integration in Corporate Module:**
- Analog zu Economic
3. **Performance-Tuning:**
```env
# Nach Bedarf anpassen:
MAX_PARALLEL_TASKS=3 # Start mit 3
TASKS_PER_VPN_SESSION=10 # Ballance zwischen IP-Rotation & Performance
MAX_TASKS_PER_INSTANCE=0 # 0 = unlimited (einfacher für Anfang)
```
4. **Monitoring:**
```bash
# Logs speichern für Analyse
RUST_LOG=info cargo run > scraper.log 2>&1
# Statistiken beobachten:

## 🚨 Wichtige Hinweise
⚠️ **Browser muss für Extension-Automatisierung sichtbar sein**
- Headless-Mode funktioniert teilweise nicht mit Extension-UI
- Bei Tests ohne Headless starten für besseres Debugging
⚠️ **ProtonVPN-Account nötig**
- Kostenlos (Free) reicht aus für diese Integration
- Free-Tier hat limitierte Server
⚠️ **IP-Rotation nicht garantiert**
- Load-Balancing auf ProtonVPN-Servern kann zu ähnlichen IPs führen
- Typischerweise aber unterschiedlich genug für Website-Scraping
⚠️ **Rate-Limiting beachten**
- VPN ändert nur Browser-Traffic, nicht Rate-Limits der Website
- Zielwebsite sieht trotzdem parallele Requests von "ähnlicher IP"
- Lösung: Tasks sequenziell ausführen oder Delays erhöhen
---
## 📞 Support
Für Fragen:
1. Lesen Sie zuerst **TROUBLESHOOTING_DE.md**
2. Überprüfen Sie `RUST_LOG=debug cargo run` Output
3. Nutzen Sie `cargo test` für Unit Tests

**Viel Erfolg mit der ProtonVPN-Integration! 🎉**

## Häufige Probleme
### Problem 1: Extension wird nicht gefunden
**Symptom:** `Failed to navigate to ProtonVPN extension popup`
**Ursache:**
- Extension nicht installiert
- Falsche Extension-ID in Konfiguration
- Chrome lädt Extension nicht automatisch
**Lösung:**
```bash
# 1. Extension ID überprüfen
# Chrome öffnen → chrome://extensions/ → ProtonVPN Details anklicken
# Extension ID kopieren und in .env eintragen
PROTONVPN_EXTENSION_ID=ghmbeldphafepmbegfdlkpapadhbakde # Aktualisieren!
# 2. Manuell in Chrome installieren
# https://chrome.google.com/webstore/detail/protonvpn/ghmbeldphafepmbegfdlkpapadhbakde
```
---
### Problem 2: "Disconnect button not found" oder "Connect button not found"
**Symptom:** Extension-Buttons werden nicht gefunden
**Ursache:**
- Extension UI hat sich geändert (Update)
- XPath-Selektoren sind veraltet
- HTML-Struktur unterscheidet sich zwischen Browser-Versionen
**Lösung:**
```rust
// 1. Browser DevTools öffnen
// Chrome: F12 → Öffne chrome-extension://[ID]/popup.html
// 2. HTML inspizieren:
// Right-click auf Button → Inspect Element
// 3. XPath-Selektoren aktualisieren
// In src/scraper/protonvpn_extension.rs:
//
// Falls neuer HTML-Struktur, z.B.:
// <button class="vpn-connect-btn">Connect</button>
//
// Neuer XPath:
let xpath = "//button[@class='vpn-connect-btn']";
// Oder alternative Strategien hinzufügen zur find_and_click_button()-Funktion
```
**Modifizierte find_and_click_button() für neue Selektoren:**
```rust
async fn find_and_click_button(&self, client: &Client, text: &str) -> Result<()> {
let lower_text = text.to_lowercase();
let xpath_strategies = vec![
// Text-basiert (case-insensitive)
format!(
"//button[contains(translate(text(), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), '{}')]",
lower_text
),
// CSS-Klassen (AnpassEN nach Bedarf)
format!("//button[contains(@class, '{}')]", text),
// Data-Attribute
format!("//*[@data-action='{}']", lower_text),
// Aria-Label
format!("//*[@aria-label='{}']", text),
// SVG + Text (für moderne UIs)
format!("//*[contains(., '{}')][@role='button']", text),
];
for xpath in xpath_strategies {
if let Ok(element) = client.find(fantoccini::LocatorStrategy::XPath(&xpath)).await {
element.click().await?;
debug!("Clicked: {}", text);
return Ok(());
}
}
Err(anyhow!("Button '{}' not found", text))
}
```
---
### Problem 3: VPN verbindet sich nicht oder Timeout
**Symptom:** `Failed to connect to ProtonVPN server 'US' within 15 seconds`
**Ursachen:**
1. ProtonVPN-Server überlastet
2. Netzwerk-Latenz
3. Falsche Server-Name
4. Browser-Erweiterung nicht vollständig geladen
**Lösungen:**
**A. Timeout erhöhen:**
```rust
// In protonvpn_extension.rs, connect_to_server():
// Erhöhe von 30 auf 60 Versuche
for attempt in 0..60 { // 30s → 60 Versuche = 30s timeout
sleep(Duration::from_millis(500)).await;
if self.is_connected(client).await.unwrap_or(false) {
return Ok(());
}
}
```
**B. Server-Namen überprüfen:**
```bash
# Gültige ProtonVPN-Server (für Free-Tier):
# US, UK, JP, NL, etc.
#
# Oder mit Nummern:
# US-Free#1, US-Free#2, UK-Free#1
# US#1, US#2 (für Plus-Tier)
# In .env überprüfen:
VPN_SERVERS=US,UK,JP,NL
# NICHT: VPN_SERVERS=US-Free#1, UK-Free#1 (zu viele Leerzeichen)
```
**C. Extension-Status überprüfen:**
```rust
// Debug: Printe HTML vor Connect-Versuch
let extension_url = format!("chrome-extension://{}/popup.html", self.extension_id);
client.goto(&extension_url).await?;
sleep(Duration::from_secs(1)).await;
let html = client.source().await?;
println!("=== EXTENSION HTML ===");
println!("{}", html);
println!("=====================");
```
---
### Problem 4: IP-Adresse wird nicht extrahiert
**Symptom:** `Failed to extract IP from whatismyipaddress.com`
**Ursache:** HTML-Struktur hat sich geändert
**Lösung:**
```rust
// In protonvpn_extension.rs, get_current_ip():
// Füge Debug-Ausgabe hinzu:
let page_source = client.source().await?;
println!("=== PAGE SOURCE ===");
println!("{}", page_source);
println!("===================");
// Dann neue Regex/Extraction-Logik basierend auf aktuellem HTML
```
**Alternative IP-Check-Services:**
```rust
// icanhazip.com (gibt nur IP zurück)
client.goto("https://icanhazip.com/").await?;
sleep(Duration::from_secs(1)).await;
let ip = client.source().await?.trim().to_string();
// ifconfig.me
client.goto("https://ifconfig.me/").await?;
sleep(Duration::from_secs(1)).await;
let ip = client.source().await?.trim().to_string();
// checkip.amazonaws.com
client.goto("https://checkip.amazonaws.com/").await?;
sleep(Duration::from_secs(1)).await;
let ip = client.source().await?.trim().to_string();
```
---
### Problem 5: Session-Manager erstellt Sessions, aber VPN verbindet nicht
**Symptom:** `VPN session created, but is_connected() returns false`
**Ursache:**
- WebDriver-Client hat Extension nicht geladen
- ChromeDriver-Instanz verwirrt zwischen mehreren Sessions
**Lösung:**
Sicherstellen, dass jeder WebDriver-Client die Extension hat:
```rust
// In webdriver.rs, ChromeInstance::new() oder new_with_extension():
// Extension-Pfad muss zu Chrome-Start mitgegeben werden
let mut cmd = Command::new("chromedriver-win64/chromedriver.exe");
cmd.arg("--port=0");
// Hinweis: Extension wird automatisch geladen, wenn in Chrome installiert
// Für Testing kann man auch Headless-Modus deaktivieren:
// cmd.arg("--headless=false"); // Damit man Browser sieht
```
---
## Konfiguration Debug
### Enable Debug Logging
```bash
# Terminal
RUST_LOG=debug cargo run
# Oder in code:
tracing_subscriber::fmt()
.with_max_level(tracing::Level::DEBUG) // Statt INFO
.init();
```
### Überprüfen Sie die geladene Konfiguration
```bash
# .env Datei überprüfen
cat .env
# Oder Ausgabe am Start ansehen
cargo run
# Output sollte zeigen:
# ✓ Config loaded | VPN: enabled | Max Parallel: 3
```
### Test-Konfigurationen
**Minimal (ohne VPN):**
```env
ENABLE_VPN_ROTATION=false
MAX_PARALLEL_TASKS=1
```
**Mit VPN, aber langsam:**
```env
ENABLE_VPN_ROTATION=true
VPN_SERVERS=US,UK
TASKS_PER_VPN_SESSION=5
MAX_PARALLEL_TASKS=1 # Nur eine Instanz für Testing
RUST_LOG=debug
```
**Mit VPN, normal:**
```env
ENABLE_VPN_ROTATION=true
VPN_SERVERS=US,UK,JP,NL,DE
TASKS_PER_VPN_SESSION=10
MAX_PARALLEL_TASKS=3
```
---
## Extension-Selektoren aktualisieren
### Wie man neue Selektoren findet
1. **Chrome öffnen:**
```
chrome://extensions/ → ProtonVPN → Details
```
2. **Popup öffnen:**
```
Navigate to: chrome-extension://[ID]/popup.html
```
3. **DevTools öffnen (F12):**
- Elements Tab
- Inspect Element (Button rechts oben)
- Klicke auf Button im Popup
4. **HTML kopieren:**
```html
<!-- Beispiel neuer Button -->
<button class="btn btn-primary" id="connect-btn">
<i class="icon-vpn"></i>
Connect
</button>
```
5. **Neuen XPath erstellen:**
```rust
// Option 1: Nach ID
"//button[@id='connect-btn']"
// Option 2: Nach Klasse
"//button[@class='btn btn-primary']"
// Option 3: Nach Text
"//button[contains(text(), 'Connect')]"
```
6. **In find_and_click_button() hinzufügen:**
```rust
let xpath_strategies = vec![
"//button[@id='connect-btn']".to_string(),
"//button[@class='btn btn-primary']".to_string(),
// ... other strategies
];
```
---
## Performance-Tipps
### 1. Batch-Processing statt paralleles Threading
```rust
// ❌ LANGSAM: Zu viele parallele Instances
let pool = ChromeDriverPool::new(10).await?;
// ✅ SCHNELLER: Weniger Instances, mehr Tasks pro Instance
let pool = ChromeDriverPool::new(3).await?;
config.max_tasks_per_instance = 20; // Recycel nach 20 Tasks
```
### 2. VPN-Verbindung optimieren
```rust
// ❌ LANGSAM: Jeder Task rotiert IP
TASKS_PER_VPN_SESSION=1
// ✅ SCHNELLER: Mehrere Tasks pro IP
TASKS_PER_VPN_SESSION=10
```
### 3. Timing anpassen
```rust
// Zu aggressive:
sleep(Duration::from_millis(100)).await;
// Besser (für VPN):
sleep(Duration::from_millis(500)).await;
// Für Disconnect/Connect Sequenzen:
// Mindestens 2-3 Sekunden zwischen Operationen
```
### 4. Server-Auswahl
```env
# ❌ Problematic: Zu viele ähnliche Server
VPN_SERVERS=US-Free#1,US-Free#2,US-Free#3,US-Free#4
# ✅ Better: Mix aus verschiedenen Ländern
VPN_SERVERS=US-Free#1,UK-Free#1,JP-Free#1,NL-Free#1
```
---
## Testing ohne VPN
### 1. VPN deaktivieren für Testing
```env
ENABLE_VPN_ROTATION=false
MAX_PARALLEL_TASKS=1
ECONOMIC_LOOKAHEAD_MONTHS=1 # Kleinere Datenmenge
```
### 2. Mock-Tests schreiben
```rust
#[tokio::test]
async fn test_vpn_session_manager() {
let mgr = VpnSessionManager::new(
vec!["US".to_string(), "UK".to_string()],
3
);
mgr.create_new_session().await.unwrap();
assert!(mgr.get_current_session().await.is_some());
}
```
### 3. Extension-Fehler isolieren
```bash
# Test nur extension.rs
cargo test --lib scraper::protonvpn_extension
```
### 4. Scraping ohne VPN testen
```bash
# Setze ENABLE_VPN_ROTATION=false
ENABLE_VPN_ROTATION=false RUST_LOG=info cargo run
```

//! Module for fetching, downloading, and extracting OpenVPN configurations from VPNBook.
//!
//! This module provides functionality to scrape the VPNBook free VPN page using
//! a headless browser, handle potential consent popups, extract current credentials,
//! collect download URLs for OpenVPN ZIP files, download them, and then extract
//! the .ovpn files into a structured directory: cache/openvpn/<hostname>/<ovpn_filename>.
//! It is designed to fetch the most recent data on every run, as credentials and
//! server configurations change periodically.

/// Fetches, downloads, and extracts the latest OpenVPN configurations from VPNBook.
///
/// This asynchronous function uses the provided `ChromeDriverPool` to scrape the
/// VPNBook free VPN page. It dismisses any consent popup if present, extracts the
/// current username and password, collects all OpenVPN ZIP download URLs, downloads
/// the ZIP files temporarily, extracts the .ovpn files into the specified directory
/// structure under `cache_dir`/openvpn/<hostname>/, and cleans up the ZIP files.
///
/// The directory structure is: cache/openvpn/<hostname>/<ovpn_filename>, where
/// <hostname> is derived from the ZIP filename (e.g., "ca149.vpnbook.com").
///
/// The function ensures fresh data is fetched each time it runs, making it suitable
/// for periodic updates where credentials may change.
///
/// # Arguments
///
/// * `pool` - A reference to the `ChromeDriverPool` for managing browser instances.
/// * `cache_dir` - The path to the base cache directory. The OpenVPN files will be saved
/// under `cache_dir`/openvpn/<hostname>/.
///
/// # Returns
///
/// A `Result` containing a tuple with:
/// - `String`: The scraped username.
/// - `String`: The scraped password.
/// - `Vec<PathBuf>`: Paths to the extracted .ovpn files.
///
/// # Errors
///
/// Returns an `anyhow::Error` if:
/// - Navigation to the page fails.
/// - The consent popup cannot be dismissed (if present).
/// - Credentials cannot be parsed from the page.
/// - Download URLs cannot be found or are invalid.
/// - HTTP downloads fail or file writing errors occur.
/// - ZIP extraction fails (e.g., invalid ZIP or I/O errors).
///
/// # Dependencies
///
/// This function requires the following crates (add to Cargo.toml if not present):
/// - `anyhow` for error handling.
/// - `fantoccini` for browser automation.
/// - `reqwest` (with `tokio` features) for HTTP downloads.
/// - `tokio` for asynchronous file operations.
/// - `url` for URL manipulation.
/// - `zip` for ZIP extraction.
///
/// # Examples
