# TG WS Proxy Go
[![Go Version](https://img.shields.io/github/go-mod/go-version/y0sy4/tg-ws-proxy-go?label=Go)](go.mod)
[![License](https://img.shields.io/badge/license-MIT-blue.svg)](LICENSE)
[![Release](https://img.shields.io/github/v/release/y0sy4/tg-ws-proxy-go)](https://github.com/y0sy4/tg-ws-proxy-go/releases)
> **Go-переосмысление** [Flowseal/tg-ws-proxy](https://github.com/Flowseal/tg-ws-proxy)
**Локальный SOCKS5-прокси для Telegram Desktop на Go**
Ускоряет работу Telegram через WebSocket-соединения напрямую к серверам Telegram.
## Почему Go версия лучше
| Параметр | Python | Go |
|----------|--------|-----|
| Размер | ~50 MB | **~8 MB** |
| Зависимости | pip (много) | **stdlib** |
| Время запуска | ~500 ms | **~50 ms** |
| Потребление памяти | ~50 MB | **~10 MB** |
## Быстрый старт
### Установка
```bash
# Скачать готовый бинарник из Releases
# Или собрать из исходников
go build -o TgWsProxy.exe ./cmd/proxy
```
### Запуск
```bash
# Windows
start run.bat
# Windows с авто-настройкой Telegram
TgWsProxy.exe --auto-config
# Linux/macOS
./TgWsProxy
# С опциями
./TgWsProxy --port 9050 --dc-ip 2:149.154.167.220
```
## Настройка Telegram Desktop
### Автоматическая настройка
При первом запуске прокси автоматически предложит настроить Telegram (Windows).
Или откройте ссылку в браузере:
```
tg://socks?server=127.0.0.1&port=1080
```
### Ручная настройка
1. **Настройки****Продвинутые****Тип подключения** → **Прокси**
2. Добавить прокси:
- **Тип:** SOCKS5
- **Сервер:** `127.0.0.1`
- **Порт:** `1080`
- **Логин/Пароль:** пусто (или ваши данные если используете `--auth`)
Или откройте ссылку: `tg://socks?server=127.0.0.1&port=1080`
## Командная строка
```bash
./TgWsProxy [опции]
Опции:
--port int Порт SOCKS5 (default 1080)
--host string Хост SOCKS5 (default "127.0.0.1")
--dc-ip string DC:IP через запятую (default "2:149.154.167.220,4:149.154.167.220")
--auth string SOCKS5 аутентификация (username:password)
--auto-config Авто-настройка Telegram Desktop при запуске
-v Подробное логирование
--log-file string Путь к файлу логов
--log-max-mb float Макс. размер логов в МБ (default 5)
--buf-kb int Размер буфера в КБ (default 256)
--pool-size int Размер WS пула (default 4)
--version Показать версию
```
### Примеры
```bash
# Без аутентификации
./TgWsProxy -v
# С аутентификацией (защита от несанкционированного доступа)
./TgWsProxy --auth "myuser:mypassword"
# Настройка DC
./TgWsProxy --dc-ip "2:149.154.167.220,4:149.154.167.220"
```

| Linux | x86_64 | ✅ Готово |
| macOS | Intel + Apple Silicon | ✅ Готово |
| Android | arm64, arm, x86_64 | 📝 См. [android/README.md](android/README.md) |
| iOS | arm64 | 🚧 В планах |
**macOS Catalina (10.15)** — поддерживается! Используйте `TgWsProxy_macos_amd64`.
## Конфигурация
Файл конфигурации:
- **Windows:** `%APPDATA%/TgWsProxy/config.json`
- **Linux:** `~/.config/TgWsProxy/config.json`
- **macOS:** `~/Library/Application Support/TgWsProxy/config.json`
```json
{
"port": 1080,

],
"verbose": false,
"log_max_mb": 5,
"buf_kb": 256,
"pool_size": 4
}
```
## Особенности

- ✅ **MTProto парсинг** — извлечение DC ID из init-пакета
- ✅ **SOCKS5** — полная поддержка RFC 1928
- ✅ **Логирование**с ротацией файлов
- ✅ **Zero-copy** — оптимизированные операции с памятью
## 📱 Планы развития

- [ ] **GUI для desktop** — системный трей для Windows/macOS/Linux
## Производительность
| Метрика | Значение |
|---------|----------|
| Размер бинарника | ~8 MB |
| Потребление памяти | ~10 MB |
| Время запуска | <100 ms |
| Задержка (pool hit) | <1 ms |
## Требования
- **Go 1.21+** для сборки
- **Windows 7+** / **macOS 10.15+** / **Linux x86_64**
- **Telegram Desktop** для использования
## Известные ограничения

# 📱 Android APK Build Guide
## Требования
Для сборки Android APK необходимо установить:
1. **Android SDK** (Android Studio или command-line tools)
2. **Go 1.21+**
3. **gomobile**
## Установка
### 1. Установи Android SDK
**Вариант A: Android Studio (рекомендуется)**
- Скачай: https://developer.android.com/studio
- Установи
- Открой SDK Manager и установи:
- Android SDK Platform (API 21+)
- Android SDK Build-Tools
- Android NDK
**Вариант B: Command-line tools только**
```bash
# Скачай command-line tools
# https://developer.android.com/studio#command-tools
# Распакуй и настрой
export ANDROID_HOME=$HOME/android-sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
```
### 2. Установи gomobile
```bash
go install golang.org/x/mobile/cmd/gomobile@latest
gomobile init
```
## Сборка APK
### Вариант 1: AAR библиотека (для интеграции в Android app)
```bash
cd mobile
gomobile bind -target android -o tgwsproxy.aar ./mobile
```
Получишь `tgwsproxy.aar` — библиотека для подключения к Android проекту.
### Вариант 2: Полное APK приложение
Для создания полноценного APK нужен Android проект с UI.
**Структура Android проекта:**
```
android/
├── app/
│ ├── src/main/java/.../MainActivity.java
│ ├── src/main/AndroidManifest.xml
│ └── build.gradle
├── build.gradle
├── settings.gradle
└── tgwsproxy.aar (из шага выше)
```
**Пример build.gradle:**
```gradle
plugins {
id 'com.android.application'
}
android {
compileSdk 34
defaultConfig {
applicationId "com.github.yosyatarbeep.tgwsproxy"
minSdk 21
targetSdk 34
versionCode 1
versionName "1.0"
}
}
dependencies {
implementation files('libs/tgwsproxy.aar')
}
```
**Сборка APK:**
```bash
cd android
./gradlew assembleDebug
# APK будет в: app/build/outputs/apk/debug/app-debug.apk
```
## Быстрая сборка (если есть Android SDK)
```bash
# В корне проекта
make android
# Или вручную
gomobile bind -target android -o android/tgwsproxy.aar ./mobile
cd android && ./gradlew assembleDebug
```
## Установка на устройство
```bash
adb install app/build/outputs/apk/debug/app-debug.apk
```
---
## 📝 Заметки
- **Min SDK:** Android 5.0 (API 21)
- **Target SDK:** Android 14 (API 34)
- **Архитектуры:** arm64-v8a, armeabi-v7a, x86_64
- **Размер APK:** ~10-15 MB (включая Go runtime)
## 🔧 Troubleshooting
### "Android SDK not found"
```bash
# Укажи путь к SDK
export ANDROID_HOME=/path/to/android-sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
```
### "NDK not found"
```bash
# Установи NDK через SDK Manager
# Или задай путь
export ANDROID_NDK_HOME=$ANDROID_HOME/ndk/<version>
```
