angularjs - Nodejs 中的 req.body 为空 :{}?

Question

这是我的 Angular http请求，当调用deleteEmployee函数时，它会发出删除请求: 单击事件时调用此函数:

$scope.deleteEmployee=function(index){
        $http({

            method:'DELETE',
            url:'/delete',
            data:{

            "ndx":"abc"

            }


        }).then((response)=>{
            console.log(response);
        })
    }

这是我的 server.js 文件

var http=require('http');
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));

app.use(bodyParser.json());


app.use('/',express.static(__dirname));

app.delete('/delete',function(req,res){

   console.log(req.body);

})

app.listen(8888,()=>{
    console.log('Server Started');
})

在 console.log(req.body) 上，它显示为空，即 {}。

来自https://www.rfc-editor.org/rfc/rfc7231#section-4.3.5 :

A payload within a DELETE request message has no defined semantics; sending a payload body on a DELETE request might cause some existing implementations to reject the request.

基本上，DELETE 请求不能有正文。
