当我尝试在nodejs中使用twilio从我的前端发送sms时，我收到了这些错误

Question

我试图通过一个自定义的API URL从我的前端发送OTP，该URL使用nodejs后端服务器来触发请求。但是我。获取以下错误。

后端代码：

const accountSid = process.env.TWILIO_ACCOUNT_SID;
const authToken = process.env.TWILIO_AUTH_TOKEN;
const client = require("twilio")(accountSid, authToken);

router.post("/notification", (req, res) => {
  const type = req.query.type || "sms";
  const ph = `+${req.query.ph}` || "";
  const email = req.query.email || "";
  const reason = req.query.reason || "notification";
  const msg = req.body.text || "";

  if (type === "sms" && reason === "auth") {
    const OTP = getRandom(1000, 2000);
    console.log(`OTP is - ${OTP}`);
    client.messages
      .create({
        body: `Hi, Im Sandip. OTP is - ${OTP}`,
        from: "+12012994953",
        to: ph,
      })
      .then((message) => res.send({ ...message, otp: OTP }))
      .catch((err) => console.log(err, "err"));
  }else{ ...some other logic }

在此URL上，我请求以下参数

http://localhost:4000/api/auth/notification?type=sms&reason=auth&ph=918697836806

我在控制台中遇到的错误

res.send()会尝试将你给它的对象串起来。根据twilio docs的说法，你想

 .then((message) => res.send({ message: message.sid, otp: OTP }))

而不是解构从他们的应用程序接口返回的整个message对象。

编辑：试试这个。我认为它做了你想要的。您应该能够从console.log中分辨出您要发回的内容。

 .then((twilioResponse) => {
   message = twilioResponse.sid
   message.otp = OTP
   console.log(message)
   res.send(message)
 } )
