Telegram, a popular messaging app, has integrated its own set of APIs for developers to interact with their users. One such API that allows developers to retrieve user contact information is called the Telegram Contact API. This article will guide you through setting up your application on Telegram and how to use the Contact API effectively.

如何使用Telegram Contact API？

注册您的应用

1. 访问Telegram Developer Portal

   • Go to https://core.telegram.org/api in your web browser.

2. Create an Account

   Sign up or log into your account if you already have one.

3. Navigate to the Contact API Section

   • In the left sidebar, find and click on "Contacts" under the "API Methods" section.
   • Click on "Get Contacts" to access the Contact API documentation.

发送和接收消息

The Contact API allows developers to send messages directly to specific contacts within Telegram. Here’s how it works:

• Send a Message: Use the sendMessage method to send a message to a contact's chat.

  from telegram import Update, Bot
  from telegram.ext import Updater, CommandHandler
  def sendMessage(bot: Bot, update: Update):
      chat_id = update.effective_chat.id
      text = "Hello! How can I help you today?"
      bot.sendMessage(chat_id=chat_id, text=text)

获取用户信息

To fetch detailed information about a user, including their username, first name, last name, and phone number, use the getUser method.

from telegram import Update, Bot
from telegram.ext import Updater, CommandHandler
def getUser(bot: Bot, update: Update):
    user = update.message.from_user
    user_name = f"{user.first_name} {user.last_name}" if user.last_name else user.first_name
    print(f"User Name: {user_name}, Username: @{user.username}")

示例代码实现

Python Example

import requests
import json
def main():
    url = 'https://api.telegram.org/bot<YOUR_BOT_TOKEN>/getUpdates'
    response = requests.get(url).json()
    for update in response['result']:
        chat_id = update['message']['chat']['id']
        sender = update['message']['from']
        # Send a message to the sender
        sendMessage(sender, chat_id)
if __name__ == '__main__':
    main()

JavaScript Example

const TelegramBot = require('node-telegram-bot-api');
const token = '<YOUR_BOT_TOKEN>';
const bot = new TelegramBot(token);
bot.onText(/\/send (.+)/i, async (msg) => {
  const match = msg.match[1];
  await bot.sendChatAction(msg.chat.id, 'typing');
  setTimeout(() => {
    // Replace this with actual logic to handle the message
    console.log(`Sent message to ${match}`);
  }, 500);
});
bot.setMyCommands(['/send', '/help']);
