Question

即时通讯试图发送短信到松弛，我有它的消息张贴。问题在于，twilio控制台在每条消息上均给出11200错误。

      console.log('Server started on port 3000')

      .catch(console.error);
      }

您收到此错误

错误-11200 HTTP检索失败

因为Twilio在向您的/sms端点发出POST请求时会收到响应。

响应必须是有效的TwiML（XML）。

更改代码：

// Handles incoming SMS to Twilio number
app.post('/sms', function (req, res) {
  const body = req.body.Body
  const num = req.body.From
    // Sends message to Slack - in format  from  {
    // `res` contains information about the posted message
    console.log('Message sent: ', res.ts);
  })
  .catch(console.error);
  }

对此：

// Handles incoming SMS to Twilio number
app.post('/sms', function (req, res) {
  const body = req.body.Body
  const num = req.body.From
    // Sends message to Slack - in format  from  {
    // `res` contains information about the posted message

    const twiml = new twilio.twiml.MessagingResponse();
    twiml.message('Your SMS was forwarded to Slack...');
    res.writeHead(200, { 'Content-Type': 'text/xml' });
    res.end(twiml.toString());

  });

如果不想回复发件人，则只需注释掉此行
// twiml.message('Your SMS was forwarded to Slack...');

我希望这会有所帮助。
