如何解决 TypeError: request.write is not a function

Question

我正在尝试通过在 hyper shell 上使用 mailchimp API 来使用 NodeJS 和 Express 制作 newsLetter 服务。我已经安装了所有必要的东西，包括 npm、express、request、https 模块。代码工作正常，直到我尝试在 mailChimp 服务器中写入用户信息并向我显示 typeError 消息：request.write() 不是函数。下面是我的代码和我的错误代码的快照。

const express = require("express");
const app = express();
const bodyParser = require("body-parser");
const request = require("request");
const https = require("https");

app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.static("public"));

app.get("/", function (req, res) {
  res.sendFile(__dirname + "/signup.html");
});

app.post("/", function (req, res) {
  const firstName = req.body.fname;
  const lastName = req.body.lname;
  const email = req.body.email;
  const password = req.body.pass;
  const cPassword = req.body.cPass;
  //console.log(firstName);
  //res.send(firstName);



var data = {
    members: [
      {
        email_address: email,
        status: "subscribed",
        merge_fields: {
          FNAME: firstName,
          LNAME: lastName
        }
      }
    ]
  };
  const jsonData = JSON.stringify(data);
  const url = "https://us1.api.mailchimp.com/3.0/lists/97d15bb1ff";
  const options = {
    method: "POST",
    auth: "Mr.M:d2f2f965b9e6b751a305bb6ce2ad7ed4-us1",
  };

  https.request(url, options, function (response) {
    response.on("data", function (data) {
      console.log(JSON.parse(data));
    });
  });

  request.write(jsonData);
  request.end();
    //res.send("hey")
});

app.listen(3000, function () {
  console.log("Server is running at port 3000");
});

Answer 1

---

res.write(jsonData)

res.end()

使用上面的代码代替 request.write(jsonData), request.end().

Answer 2

https.request(url, options, function (response) {
response.on("data", function (data) {
  console.log(JSON.parse(data));
});   });

改为使用这个：

const request = https.request(url, options, function (response) {
response.on("data", function (data) {
  console.log(JSON.parse(data));
});

});

正如 Lingyu Kong 已经指定的，您需要将您的请求保存在一个常量变量中，以便您以后调用它：

下面的 node.js 网站链接完美地说明了这一点：
