Question

我的API无法找到我的帖子参数这是代码：

var express = require("express");
var bodyParser = require('body-parser');
var redis = require ('redis'); 
var tools = require('./Read');

var app = new express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

client= redis.createClient();   

app.get("/Json", function(req,res){
  let b = req.query.Menù;
  var secondomenu = new tools.Menu("secondo","secondo",2);
  var stringa="";
  var a = b.toString().split('p');

  let ciao =new tools.Menu(a[0],a[1],a[2]);
  let c =[];
  c.push(ciao);
  c.push(secondomenu);
  for (var i =0; i<c.length; i+=1)
  {
    stringa  +=  retMen(c[i]);
  }
  client.hset("hash key", "Menu1",JSON.stringify(c), redis.print);

  res.send(stringa);
});

app.post("/Save", function(res,req){
  var guid = req.body.guid;
  var idMenu = req.body.idMenu;
  var Menu = req.body.Menu;
  client.hset(guid, idMenu, Menu, redis.print);
  res.send("Tutto OK");
}) 

function retMen (Menu) {
  return (Menu.IdMenù+ "  "+ Menu.desc+ "  " +Menu.Vote);
};

app.listen(11100);

这就是错误

监听ws：//127.0.0.1的调试器：29026 / e0f09df5-7d1d-4356-bec8-c2a4becabc96 TypeError：无法读取未定义的属性'guid' 的application.js：630

有人能帮助我吗？

Answer 1

app.post("/Save", function(req,res)
{

var guid = req.body.guid;
var idMenu = req.body.idMenu;
var Menu = req.body.Menu;
client.hset(guid, idMenu, Menu, redis.print);
res.send("Tutto OK");
})

req，res而不是res，req

NodeJs Express post，error req.body undefined
