我为rest api创建了main.js.当我从vericek.js向本地服务器发送请求时，响应没有返回，但localserver显示在终端中发送数据。问题是什么。谢谢

          </ul>  
      </div>

</html>

vericek.js

var app=angular.module("app",[]);
app.controller("ctrl",function($scope, $http) {

    $scope.getData=function() {
        $http.get("http://127.0.0.1:1305/listuser").success(function(response){
            $scope.veriler=response.userInfo;   
       });    
    }
});

main.js / rest api

var express=require("express");
var app=express();
var host="127.0.0.1";
var port="1305";
var fs=require("fs");
app.get("/listuser",function(request,response){

    fs.readFile(__dirname+"/"+"user.json","utf-8",function(error,data){
        if(error){
            response.writeHead(404,{"Content-Type":"text/plain"});
            response.end("Page Not Found");
        } else {
            console.log("sent data:"+data);
            response.writeHead(200,{"Content-Type":"text/json"});
            response.end(data);
        }
    });  
});

var server=app.listen(port,host,function(){
   console.log("Listening port ..");
});

user.json

{
    "userInfo":[
        {
            "id":"1",
            "username":"ali",
            "date":"1.1.2016",
            "post":"this is a post",
            "like":"2",
            "liked":false
        },
        {
            "id":"2",
            "username":"veli",
            "date":"2.3.2015",
            "post":"Everyting nonsense",
            "like":"0",
            "liked":false
        }
    ]
}

我认为你在main.js中使用了错误的结尾。

response.end（）只是结束响应过程，它不会发送任何数据。

您想使用response.send（数据）
