我是nodeJs的初学者。我只想在nodeJs中接收GET和POST数据。
我尝试并成功获取GET数据，但是在POST数据中出现错误ReferenceError：setImmediate未定义。当我运行server.js时$ node server.js，它将在3000端口监听并重定向到index.html页面和通过错误。
我为它做了Google，但没有找到解决我的错误的方法。
我正在附上代码。
server.js
var express = require("express");
var bodyParser = require("body-parser");
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.get('/',function(req,res){
res.sendFile(__dirname+"/index.html");
});
app.post('/login',function(req,res){
var user_name=req.body.user;
var password=req.body.password;
console.log("User name = "+user_name+", password is "+password);
res.end("yes");
});
app.listen(3000,function(){
console.log("Started on PORT 3000");
})
package.json
{
"dependencies":
{
"express":"*",
"body-parser":"*"
}
}
index.html
<html>
<head>
<title>Simple login</title>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"> </script>
<script>
$(document).ready(function(){
var user,pass;
$("#submit").click(function(){
user=$("#user").val();
pass=$("#password").val();
$.post("http://localhost:3000/login",{user: user,password: pass}, function(data){
if(data==='done')
{
alert("login success");
}
});
});
});
</script>
</head>
<body>
<h1>Hello people !</h1>
<input type="TEXT" id="user" size="40"><br>
<input type="password" id="password" size="40"><br>
<input type="button" id="submit" value="Submit">
</body>
</html>
我得到的错误：
