Answer 1

我没有找到任何 php代码，但是这个 nodejs片段对我有用，所以我把它放在让你知道它是如何工作的。

创建一个机器人(开始在你的电报中与@botfather 聊天)

bot创建完成后，会给你一个HTTP API的token

$ npm install --save node-telegram-bot-api

创建 js node_modules旁边的文件文件夹(例如:server.js)

将此代码放入 server.js文件，然后用 $ node server.js 运行它

    const TelegramBot = require('node-telegram-bot-api');
    // replace the value below with the Telegram token you receive from @BotFather  
    const token = 'XXXX35XXXX:XXXX7DCYw5IsY6DHcwXXXXXXXXX';
    // Create a bot that uses 'polling' to fetch new updates    
    const bot = new TelegramBot(token, {
        polling: true
    });
    // Matches "/echo [whatever]"    
    bot.onText(/\/echo (.+)/, (msg, match) => {
        // 'msg' is the received Message from Telegram    
        // 'match' is the result of executing the regexp above on the text content    
        // of the message    

        const chatId = msg.chat.id;
        const resp = match[1]; // the captured "whatever"    

        // send back the matched "whatever" to the chat    
        bot.sendMessage(chatId, resp);
    });
    // Listen for any kind of message. There are different kinds of  
    // messages.  
    bot.on('message', (msg) => {
        const chatId = msg.chat.id;
        var user_profile = bot.getUserProfilePhotos(msg.from.id);
        user_profile.then(function (res) {
            var file_id = res.photos[0][0].file_id;
            var file = bot.getFile(file_id);
            file.then(function (result) {
                var file_path = result.file_path;
                var photo_url = `https://api.telegram.org/file/bot${token}/${file_path}`
                bot.sendMessage(chatId, photo_url);
            });
        });
    });
