Telegram Bot in C++

This repository contains a Telegram Bot implemented in C++. The bot is designed to handle user commands, enforce rate limits, and interact with the Telegram API to send and receive messages. It is a robust and scalable solution for building custom Telegram bots with advanced features.

Features

• Command Handling: Register and execute custom commands dynamically.
• Rate Limiting: Prevent abuse by limiting user requests within a specified time interval.
• Telegram API Integration: Send and receive messages with optional Markdown formatting.
• Thread Safety: Ensures safe access to shared resources using mutexes.
• JSON Parsing: Processes Telegram API responses using JsonCpp.
• Logging: Provides detailed logs for debugging and monitoring bot activity.

Getting Started

Prerequisites

• libcurl: For HTTP requests and URL encoding.
• JsonCpp: For parsing JSON responses.
• C++ Compiler: Supports C++11 or later.

Installation

Linux

1. Clone the repository: bash git clone https://github.com/genyleap/telegram-bot cd telegram-bot

2. Install dependencies: bash sudo apt-get install libcurl4-openssl-dev libjsoncpp-dev

3. Build the project: bash mkdir build cd build cmake .. make

4. Run the bot: bash ./TelegramBot YOUR_TELEGRAM_BOT_TOKEN

Windows

1. Clone the repository: bash git clone https://github.com/genyleap/telegram-bot cd telegram-bot

2. Install dependencies:

   • Download and install vcpkg for managing dependencies.
   • Install libcurl and jsoncpp using vcpkg: bash vcpkg install curl jsoncpp

3. Build the project:

   • Open the project in Visual Studio or use CMake: bash mkdir build cd build cmake -DCMAKE_TOOLCHAIN_FILE=[path-to-vcpkg]/scripts/buildsystems/vcpkg.cmake .. cmake --build .

4. Run the bot: bash .\TelegramBot YOUR_TELEGRAM_BOT_TOKEN

macOS

1. Clone the repository: bash git clone https://github.com/genyleap/telegram-bot cd telegram-bot

2. Install dependencies: bash brew install curl jsoncpp

3. Build the project: bash mkdir build cd build cmake .. make

4. Run the bot: bash ./TelegramBot YOUR_TELEGRAM_BOT_TOKEN

Usage

Registering Commands

You can register custom commands with the bot: ```cpp TelegramBot bot("YOURTELEGRAMBOT_TOKEN");

bot.registerCommand(Command("start", { bot.sendMessage(chatId, "Welcome to the bot!"); }));

bot.registerCommand(Command("help", { bot.sendMessage(chatId, "Available commands: /start, /help"); }));

bot.start(); ```

Sending Messages

The bot can send messages with optional Markdown formatting: cpp bot.sendMessage(chatId, "Hello, world!", true); // Markdown enabled

Configuration

• Rate Limiting: Adjust the rate limit settings in the RateLimiter constructor: cpp RateLimiter rateLimiter(5, std::chrono::seconds(10)); // 5 requests per 10 seconds

• Logging: Customize logging levels and output as needed.

Example Commands

• /start: Welcomes the user.
• /help: Lists available commands.
• Add custom commands to suit your bot's functionality.
