Question

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

const app = express();

// keep static files (e.g css,image files) inside a folder called 'Public'
app.use(express.static("public"));

app.use(bodyParser.urlencoded({extended: true})) ;

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

app.post( "/", (req, res) => {
    const firstName = req.body.fName ;
    const lastName = req.body.lName ;
    const email = req.body.eMail ;
    let data = {
        members: [
            {
                email_address: email,
                status: "subscribed",
                merge_fields: {
                    FNAME: firstName,
                    LNAME:lastName
                }
            }
        ]
    }

    const jsonData = JSON.stringify(data);
    const url = "https://us7.api.mailchimp.com/3.0/lists/0457e81530";
    const options = {
        method: "POST" ,
        auth: "Jewel:a940bdffbeedd3146d8722711e7c4e98-us7"
    }
    const request = https.request(url, options, (response) => {
        response.on("data", (data) => {
            console.log(JSON.parse(data));
        })
    });
    request.write(jsonData);
    request.end;
});

app.listen( process.env.PORT || 3000, function () {
    console.log("server is running on port 3000") ;
});

Answer 1

如果您想继续使用 https 模块：

const request = https.request(url, options, (response) => {
  let data = '';
  response.on("data", (chunk) => {
    data += chunk;
  });
  response.on("end", () => {
    const result = JSON.parse(data);
    console.log(result);
    res.send(result);
  });
});

Answer 2

你的网址是错误的。使用邮递员应用并发布该网址，您将看到返回错误页面。

我相信你最后缺少的“/members”。添加到您的选项“正文：数据” 并且您的数据不应该是数组，而应该是对象（这是我在处理上述 2 条建议后发现的错误）。

使用 Node.js 获取 SyntaxError: Unexpected token < in JSON at position 0 at JSON.parse (<anonymous>)"
