Node 作为客户端(中转站)发送POST请求

let http = require('http')
let https = require('https')
let url = require('url')  // 用于解析url地址

const app = http.createServer((req, res) => {
    let urlobj = url.parse(req.url, true) // 转换为对象
    console.log(urlobj);
    res.writeHead(200, {
        "Content-Type": "application/json;charset=utf-8",
        "access-control-allow-origin": "*" // 允许所有域通过控制
    })
    switch (urlobj.pathname) {
        case '/api/user':
            httpsPOST((data) => res.end(data))
            break
        default:
            res.end('404')
            break
    }
})

app.listen(8080, () => {
    console.log('localhost:8080')
})

function httpsPOST(response) {
    // https://m.xiaomiyoupin.com/mtop/mf/resource/data/batchList
    let list = ''
    const options = {
        hostname: 'm.xiaomiyoupin.com', // 域名
        port: '443', //端口号
        path: '/mtop/mf/resource/data/batchList', // 路径
        method: 'POST', // 请求方式
        headers: {
            "content-type": "application/json; charset=utf-8"  // json格式
        }
    }
    let req = https.request(options, (res) => {  // request发送post请求
        res.on('data', chunk => {
            list += chunk
        })
        res.on('end', () => {
            response(list)
        })
    })
    // https.get('https://i.maoyan.com/api/mmdb/movie/v3/list/hot.json?ct=%E5%98%89%E5%85%B4&ci=185&channelId=4',(res)=>{
    //     res.on("data",(data)=>{
    //         list+=data
    //     })   // 有数据返回就会触发,数据流的方式一点一点的返回
    //     res.on('end',()=>{  // 数据合并到一起后,end可以拿到完整数据
    //         response(list)
    //     })
    // })
    req.write(JSON.stringify([{}, ["newer_popup_ad", "download_options"]])) // 发送字符串
    req.end()
}

前端:

<script>
        fetch('http://127.0.0.1:8080/api/user').then(res => res.json()).then(res => {
            console.log(res);
        })
    </script>
