案例1

index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Cors</title>
</head>
<body>
    <script>
        fetch("http://localhost:3000/api/aaa").then(res=>res.json()).then(res=>{
            console.log(res)
        })
</script>
</body>
</html>

index.js

var http=require("http")
var url=require("url")
http.createServer((req,res)=>{
     var urlobj=url.parse(req.url)
     res.writeHead(200,{
        "content-Type":"application/json;charset=utf-8",
        "access-control-allow-origin":"*"
     })
     switch(urlobj.pathname){
        case "/api/aaa":
            res.end(JSON.stringify({
                name:"geyao",
                age:100
            }))
            break
        default:
            res.end("404")
     }


}).listen(3000)

运行结果

前言

我是歌谣微信公众号关注前端小歌谣一起学习前端知识今天继续给大家讲解node中post请求的讲解

案例

var http=require("http")
var url=require("url")
var https=require("https")
http.createServer((req,res)=>{
     var urlobj=url.parse(req.url)
     res.writeHead(200,{
        "content-Type":"application/json;charset=utf-8",
        "access-control-allow-origin":"*"
     })
     switch(urlobj.pathname){
        case "/api/aaa":
            httppost((data)=>{
                res.end(data)
            })
            break
        default:
            res.end("404")
     }
}).listen(3000)


function httpget(response){
    var data=""
    https.get(`https://i.maoyan.com/api/mmdb/movie/v3/list/hot.json`,(res)=>{
        res.on("data",(chunk)=>{
           data+=chunk
        })
        res.on("end",()=>{
           console.log(data)
           response.end(data)
        })
    })
}


function httppost(cb){
    var options={
        hostname:"m.xiaomiyoupin.com",
        port:"443",
        path:"/mtop/market/search/placeHolder",
        method:"POST",
        headers:{
            "Content-Type":"application/json"
        }
    }
    var data=""
    var req=https.request(options,(res)=>{
        res.on("data",chunk=>{
            data+=chunk
        })
        res.on("end",()=>{
            cb(data)
        })
    })
   
    req.write(JSON.stringify([{},{"baseParams":{"ypClient":1}}]))
    req.end()
}

运行结果
