嗨，我一直面临着一个铬合金的问题。我不知道是我的代码错误还是Chrome错误。错误之处在于

加载资源失败：NET：：ERR_CONNECTION_CLOSED

我的QSTNURL是const app = angular.module('myapp',["ngRoute"]);app.value("QSTNURL","https://localhost:12345/api/insertQuestion");

来自客户端的控制程序.js是

app.controller('myctrl',function($scope,userFactory,QSTNURL){
  $scope.pushData = function(){
  var qstn = $scope.qstn;
  var opt1 = $scope.opt1;
  var opt2 = $scope.opt2;
  var opt3 = $scope.opt3;
  var opt4 = $scope.opt4;
  var ans = $scope.ans;
  const qstnObject = {
      "qstn":qstn,
      "opt1":opt1,
      "opt2":opt2,
      "opt3":opt3,
      "opt4":opt4,
      "ans":ans
  }
  console.log('doAjax');
  var promise = userFactory.doAjax(QSTNURL,qstnObject);
  promise.then(function(response){
      $scope.data = response;
   },function(error){
      $scope.error = error;
  });
 }

});

我对服务器的AJAX调用是

app.factory("userFactory",function($http,$q){
  var userObject = {
    doAjax(QSTNURL,qstnObject){
        console.log('doAjax()');
            var defer = $q.defer();
            $http.get(QSTNURL,qstnObject).then(function(response){
                defer.resolve(response);
                console.log("doAjax 2");
            },function(error){
                defer.reject(error);
            });
            return defer.promise;

    }
  };
   return userObject;
});

Server.js

const express = require("express");
 var expressSession = require('express-session');
 const app = express();
 var path = require("path");
 var bodyParser = require('body-parser');
 const userRoutes = require("./routes/userroutes");
 app.set('views', path.join(__dirname, 'views'));
 app.set('view engine', 'ejs');

 app.use(express.static(path.join(__dirname, 'public')));
 app.use(expressSession({secret: 'mySecretKey'}));

 app.use('/api',userRoutes);

 app.use(bodyParser.urlencoded({ extended: false }));
 app.use(bodyParser.json());

 app.use('/',userRoutes);
 app.listen(12345,()=>{
 console.log("Server Start...");
});

我的所有静态文件(如：-用于生成SPA的所有js文件，例如app.js、控制器、工厂等)位于公用文件夹中，而视图部件位于视图文件夹中

我的路线代码是

router.get('/insertQuestion',(req,response)=>{
  console.log("insertQuestion");
  var qstn = req.body.qstn;
  var opt1 = req.body.opt1;
  var opt2 = req.body.opt2;
  var opt3 = req.body.opt3;
  var opt4 = req.body.opt4;
  var ans = req.body.ans;
  var qstnObject = new Insert(qstn,opt1,opt2,opt3,opt4,ans);
  userOperation.insertQuestion(qstnObject,response,req);
  response.json("question inserted");
});
