(1)body-parser

安装body-parser

npm install -g body-parser

使用

//引入
const bodyParser=require(``"body-parser"``);

// 解析以 application/json 和 application/x-www-form-urlencoded 提交的数据
var jsonParser = bodyParser.json();
var urlencodedParser = bodyParser.urlencoded({ extended: ``false` `});

//json={"path":"./123/1212/123","fileName":"hj"}
app.post("/",urlencodedParser,``function``(req,res){
    let data=req.body;
    let path=data.path;
    let fileName=data.fileName;
    res.send(req.body);
});

(2)Express4.16+已经加入了bodyParser,不需要再require,可直接作为express的方法使用.

const express = require('express');
var urlencodedParser = express.urlencoded({ extended: false })

//json={"path":"./123/1212/123","fileName":"hj"}
app.post("/",urlencodedParser,``function``(req,res){
    let data=req.body;
    let path=data.path;
    let fileName=data.fileName;
    res.send(req.body);
});

GET

 app.post(`"/"`,``function``(req,res){
     let appName=req.query["appName"];
    res.send(appName);
});
