hi I have been facing a problem in chrome. I don't know if it is my code fault or the chrome fault. And the error is
Failed to load resource: net::ERR_CONNECTION_CLOSED
my QSTNURL is
const app = angular.module('myapp',["ngRoute"]); app.value("QSTNURL","");
my controller.js from client side is
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){
$scope.error = error;
});
}
});
And my ajax call to server is
app.factory("userFactory",function($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...");
});
my all the static files(like:- all js files to make SPA e.g. app.js, controller, facotry etc.) are in public folder and view part in views folder
my routes code is
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");
});

This error only happens if you have no server running on the 12345 port.
You are calling . So you should also consider that you are using https scheme so make sure your server supports https scheme and port is proper.
If you haven't configured your node app/server app to run on https then just replace
with
hey I got the answer the whole problem was in the QSTNURL. I should not have passed this URL while pass only api/insertQuestion directly to the AJAX call like this
app.factory("userFactory",function($http,$q){
var userObject = {
doAjax(QSTNURL,qstnObject){
console.log('doAjax()');
var defer = $q.defer();
$http.get('/api/insertQuestion',qstnObject).then(function(response){
defer.resolve(response);
console.log("doAjax 2");
},function(error){
defer.reject(error);
});
return defer.promise;
}
};
return userObject;
});
I don't know why it is so. but It removed my problem
