node.js - 有人知道如何使用 NodeJs 将音频/图像发送到 Telegram 机器人吗？

Question

我正在尝试使用 node 和 Telegram Api 将音频文件发送到 Telegram 机器人(在本例中为 sendAudio)

const axios = require('axios');
const FormData = require('form-data');

let payload = new FormData();
payload.append('chat_id', 'ID');
payload.append('audio', './audio.mp3');
// OR  payload.append('photo', fs.createReadStream(`./audio.jpg`));

axios.post(
    'https://api.telegram.org/botMyToken/sendAudio',
    payload,
    {
        headers: {
            'accept': 'application/json',
            'Content-Type': `multipart/form-data;`
        }
    })
    .then(function (response) {
        console.log(response);
    })
    .catch(function (error) {
        console.log(error);
    });

控制台结果是一个大对象:

Error: Request failed with status code 400

at process._tickCallback (internal/process/next_tick.js:114:19) 

headers:
  { Accept: 'application/json, text/plain, */*',
    'Content-Type': 'multipart/form-data;',
    accept: 'application/json',
    'Accept-Language': 'en-US,en;q=0.8',
    'User-Agent': 'axios/0.18.0' },
  method: 'post',
  url: 'https://api.telegram.org/botMyToken/sendAudio',
  data:
   FormData {
    _overheadLength: 210,
    _valueLength: 89,
    _valuesToMeasure: [],
    writable: false,
    readable: true,
    dataSize: 0,
    maxDataSize: 2097152,
    pauseStreams: true,
    _released: true,
    _streams: [],
    _currentStream: null,
    _boundary: '--------------------------432591578870565694802709',
    _events: {},
    _eventsCount: 0 } },

我做错了什么？我尝试使用简单的表单发送相同的文件，并且 PHP 有效，我不明白这段代码有什么问题。

您发送的不是音频文件，而是包含文件本地路径的字符串，Telegram 当然无法访问该路径。

Audio file to send. Pass a file_id as String to send an audio file that exists on the Telegram servers (recommended), pass an HTTP URL as a String for Telegram to get an audio file from the Internet, or upload a new one using multipart/form-data.

电报文档很清楚，音频必须是:

• 文件 ID
• 网址
• 使用 multipart/form-data 发布文件

你可以试试这个:

payload.append('audio', fs.createReadStream('./audio.mp3'));

我建议使用telegraf这将完成所有繁重的工作，并允许您使用本地文件路径。

const bot = new Telegraf(process.env.BOT_TOKEN);

bot.on('message', (ctx) => {

  // send file
  ctx.replyWithAudio({ source: './audio.mp3' })

});

bot.startPolling();
