Javascript 获取POST请求不存在'；t返回使用res.send（'；sampletext'；）发送的响应；

我有一个云函数，它是使用来自客户端浏览器的fetch POST请求触发的，但是对fetch调用的响应不包含来自云函数的响应文本（res.send（“sampletext”））

云功能：

const functions = require('firebase-functions');
const cors = require('cors')({ origin: true })

exports.unlock = functions.https.onRequest((req, res) => {
    cors(req, res, () => {
        res.send('bsdasda');
    })
})

在客户端浏览器上获取POST请求

fetch("https://us-central1-closing-ratio-32360.cloudfunctions.net/unlock", {
  method: "post",
  mode: "cors"

}).then((response) => {
  console.log(response)
});

Response {type: "cors", url: "https://us-central1-closing-ratio-32360.cloudfunctions.net/unlock", redirected: false, status: 200, ok: true, …}
body
:

bodyUsed

type

"https://us-central1-closing-ratio-32360.cloudfunctions.net/unlock"

这是客户端浏览器上的获取响应

fetch("https://us-central1-closing-ratio-32360.cloudfunctions.net/unlock", {
  method: "post",
  mode: "cors"

}).then((response) => {
  console.log(response)
});

Response {type: "cors", url: "https://us-central1-closing-ratio-32360.cloudfunctions.net/unlock", redirected: false, status: 200, ok: true, …}
body
:
(...)
bodyUsed
:
false

ok
:

redirected

status

type

看看这个：

fetch("https://us-central1-closing-ratio-32360.cloudfunctions.net/unlock", {
  method: "post",
  mode: "cors"
})
.then((response) => response.text())
.then((text) => {
  console.log(text)
});
