Hi thanks in advance for the help.
We're running a mobile web app that has been working fine on all browsers when it originally went live earlier this year.
About the app:
Running on IIS 8.5.
Certificate is from LetsEnctrypt.org
REST web service is running on .NET Web API 2.
Front end is AngularJS
Sample Ajax Call:
$http.post('/api/User/Validate', loginData)
.then(function (response) {
alert("_login.Success: " + JSON.stringify(response, null, 4));
if (response.data.StatusCode == 200) {
//console.log("Successfult Validate" + response);
var token = response.data.Data[0].Token;
var authData = {
token: token.TokenStr,
expiryDate: token.ExpiryDate,
companyId: response.data.Data[0].CompanyId,
userId: response.data.Data[0].UserId
};
_setAuthData(authData);
deferred.resolve(response.data);
}
else {
console.log("Error while validating ", response);
deferred.resolve(response.data);
}
}, function (err, status) {
alert("_login.Error: " + JSON.stringify(err, null, 4) + " " + status);
_logOut();
deferred.reject(err);
});
I've added debug logging to troubleshoot this and i see the request hit that backend without any errors that i can see but when the browser gets the request the error callback function gets executed instead of the success one. If i try the same code through http it works perfectly.
Thoughts?
Thanks!

I have built a simple Api that returns a few places with associated data, and everything works fine, but i have a more specific research method that also is working fine in testing phase using Postman. I've made a few requests in my web application and they receive expected result, but now I've come to the point where I need to call this method I made, which returns proper response on Postman but 404 on my web application when I log the response message.
This is how I make my request:
<script>
function getCities() {
var selectedRegion = document.getElementById("region_select").value;
$.ajax({
type: "GET",
url: '#Url.Action("ShowCitiesByRegion", "ClientTourism")',
accepts: "/",
data: {
regionId: selectedRegion
},
success: function (data) {
$('#city_select_div').html(data);
},
failure: function (response) {
console.log(response.responseText);
},
});
console.log(selectedRegion);
}
</script>
This request calls up my controller, which looks like this:
public async Task<IActionResult> ShowCitiesByRegion(int regionId)
{
System.Diagnostics.Debug.WriteLine("ID DA REGIAO-" + regionId);
List<City> cities = new List<City>();
HttpClient httpClient = _api.Initial();
HttpResponseMessage httpResponseMessage = await httpClient.GetAsync("api/Cities/region_cities/region=" + regionId);
if (httpResponseMessage.IsSuccessStatusCode)
{
var response = httpResponseMessage.Content.ReadAsStringAsync().Result;
cities = JsonConvert.DeserializeObject<List<City>>(response);
System.Diagnostics.Debug.WriteLine("Cidades-" + cities);
}
else
{
System.Diagnostics.Debug.WriteLine("Erro" + httpResponseMessage);
}
return PartialView(cities);
}
This controller calls up the api and it never gets a SuccessStatusCode.
My API console run never indicates it is receiving the request, except when its coming from Postman.
I've narrowed the problem to the request making, although I checked every variable and every data is passing through view to controller as expected. It returns this response message:
Cant seem to figure why I am always getting 404 while doing this request from my web application.
Try to write the complete url in httpclient:
"https://hostname/api/Cities/region_cities/region=" + regionId
I am using cordova-plugin-advanced-http plugin for API calling and all JSON enabled API working fine but I have one XML embedded API which is working fine in Postman but while I call it from ionic its param not getting at the server end.
Below is my code for XML API:
Type 1:
let headers = {
"Content-type": 'text/xml; charset=utf-8',
"Authorization": token,
};
let xmlBody =
'<ServiceRequest>' +
'<CaseNumber>' + caseNumber +
'</CaseNumber>' +
'</ServiceRequest>'
this.httpPlugin.setDataSerializer('utf8');
this.httpPlugin.post('https://test.com/Service', xmlBody, headers).then((response) => {
console.log("XML Response : ", JSON.stringify(response.data));
xml2js.parseString(response.data, function (err, result) {
console.log("XML parser success:", result);
console.log("XML parser error:", err);
if (result) {
resolve(result);
} else {
reject(err);
}
});
}).catch(error => {
if (error.status == 403) {
console.log("Token expired : " + JSON.stringify(error));
} else {
console.log("Error : " + error.error);
console.log("Error " + JSON.stringify(error));
reject(error);
}
});
Type 2:
let xmlBody = '<ServiceRequest>' +
'<CaseNumber>' + caseNumber +
'</CaseNumber>' +
'</ServiceRequest>';
console.log("XML Body", xmlBody)
// this.httpPlugin.setRequestTimeout(60);
this.httpPlugin.setDataSerializer('utf8');
this.httpPlugin.setHeader('*', 'authorization', token);
this.httpPlugin.setHeader('*', 'Content-Type', "application/x-www-form-urlencoded");
this.httpPlugin.post('https://test.com/Service', xmlBody, {}).then((response) => {
console.log("XML Response : ", JSON.stringify(response.data));
xml2js.parseString(response.data, function (err, result) {
console.log("XML parser success:", result);
console.log("XML parser error:", err);
if (result) {
resolve(result);
} else {
reject(err);
}
});
}).catch(error => {
if (error.status == 403) {
console.log("Token expired : " + JSON.stringify(error));
} else {
console.log("Error : " + error.error);
console.log("Error " + JSON.stringify(error));
reject(error);
}
});
All the time it's throwing errors from the server and with the same request, I am able to get data in postman as well as Native iOS code.
I referred this issue on GitHub but still no success.
Something I am missing though it's not able to get data on the server.
Help me to solve this issue.
After struggling a lot on this issue I found a solution to clean my request cookies.
In the HTTP Advanced plugin, there is one method to clear my cookies.
clearCookies()
Clear all cookies.
Use this method before calling any API.
So what it will do clear all my cookies and my issue related to old cookies will be solved in this way.
constructor(
public storage: Storage,
public httpPlugin: HTTP,
private platform: Platform
) {
// enable SSL pinning
httpPlugin.setSSLCertMode("pinned");
//Clear old cookies
httpPlugin.clearCookies();
}
The above code solves my issue.
Thanks all for your quick guidance and suggestions.
comment on this if this is not the right way to clear my old request data.
I'm trying to make real time application with node.js and socket.io. As I can see the server can see when new user connects but can't return information to client side or something. This is what I've on client side:
<script src="<?= base_url('assets/js/socket.io.js') ?>"></script>
<script>
var socket;
socket = io('http://***.***.***.***:3030', {query: "key=key"});
socket.on('connect', function (data) {
console.log('Client side successfully connected with APP.');
});
socket.on('error', function (err) {
console.log('Error: ' + err);
});
</script>
and this is the server side:
var app = require("express")();
var http = require("http").createServer(app);
var io = require("socket.io")(http);
http.listen(3030, function () {
globals.debug('Server is running on port: 3030', 'success');
});
io.set('authorization', function (handshakeData, accept) {
var domain = handshakeData.headers.referer.replace('http://', '').replace('https://', '').split(/[/?#]/)[0];
if ('www.****.com' == domain) {
globals.debug('New user connected', 'warning');
} else {
globals.debug('Bad site authentication data, chat will be disabled.', 'danger');
return accept('Bad site authentication data, chat will be disabled.', false);
}
});
io.use(function (sock, next) {
var handshakeData = sock.request;
var userToken = handshakeData._query.key;
console.log('The user ' + sock.id + ' has connected');
next(null, true);
});
and when someone comes to website I'm expecting to see in console output "New user connected" and I see it: screen shot and the user should see on the browser console output: "Client side successfully connected with APP." but I doesn't show. Also I tried to emit data to user but it doesn't work too. I can't see any errors or something. This is not the first time I'm working with sockets but the first time facing such as problem. Maybe there is any error reporting methods to handle errors or something? Also I can't see output on io.use(....) method
The solution is to pass "OK" sign just after authenticating to do the next method:
io.set('authorization', function (handshakeData, accept) {
var domain = handshakeData.headers.referer.replace('http://', '').replace('https://', '').split(/[/?#]/)[0];
if ('www.****.com' == domain) {
globals.debug('New user connected', 'warning');
accept(null, true);
} else {
globals.debug('Bad site authentication data, chat will be disabled.', 'danger');
return accept('Bad site authentication data, chat will be disabled.', false);
}
});
I am currently trying to login to my app that is built on Ionic Framework using Venmo's Oauth API. I am attempting to use the Server Side Flow so that I can have a longer term access token. I am able to receive a code and set it to a requestToken variable.
However, when I attempt to post to "https://api.venmo.com/v1/oauth/access_token" with my Client Id, Client Secret, and Request Token, I get the following error alert: "ERROR: [object Object]".
In checking my console, I see that the error is a 400 Bad Request error coming on my post request, although it does appear that I have a valid request token. The error message is as follows: "Failed to load resource: the server responded with a status of 400 (Bad Request)".
Below is the code of the login function I am using to login via Venmo's Oauth API:
//VENMO SERVER SIDE API FUNCTION
var requestToken = "";
var accessToken = "";
var clientId = "CLIENT_ID_HERE";
var clientSecret = "CLIENT_SECRET_HERE";
$scope.login = function() {
var ref = window.open('https://api.venmo.com/v1/oauth/authorize?client_id=' + clientId + '&scope=make_payments%20access_profile%20access_friends&response_type=code');
ref.addEventListener('loadstart', function(event) {
if ((event.url).startsWith("http://localhost/callback")) {
requestToken = (event.url).split("?code=")[1];
console.log("Request Token = " + requestToken);
$http({
method: "post",
url: "https://api.venmo.com/v1/oauth/access_token",
data: "client_id=" + clientId + "&client_secret=" + clientSecret + "&code=" + requestToken
})
.success(function(data) {
accessToken = data.access_token;
$location.path("/make-bet");
})
.error(function(data, status) {
alert("ERROR: " + data);
});
ref.close();
}
});
}
if (typeof String.prototype.startsWith != 'function') {
String.prototype.startsWith = function(str) {
return this.indexOf(str) == 0;
};
}
This function is from this helpful walkthrough article by Nic Raboy (https://blog.nraboy.com/2014/07/using-oauth-2-0-service-ionicframework/). I think that the problem may be in how I am presenting the data array, so if anyone has any experience in successfully implementing a Venmo API in Ionic, your help would be much appreciated!
I was actually able to solve this issue with the method described above. In my original code, I omitted the line used to set the content type to URL encoded (which was included in Nic's example). Once I added this line, the request functioned as expected. The line was as follows:
$http.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
I'm developing iOS app using ionic framework and I have one problem when I try to call web service by using 3G network.
here is my service in UserService:
function getUserStat(user_id){
var request = $http({ method: "get",
url: "http://www.example.com/user.php",
params: {
action: "stat",
user_id:user_id
},
data: {
}
});
return(request.then(handleSuccess, handleError));
}
function handleError( response ) {
// The API response from the server should be returned in a
// nomralized format. However, if the request was not handled by the
// server (or what not handles properly - ex. server error), then we
// may have to normalize it on our end, as best we can.
if (!angular.isObject( response.data ) || !response.data.message) {
return( $q.reject("An unknown error occurred.") );
}
// Otherwise, use expected error message.
return( $q.reject( response.data.message ) );
}
// I transform the successful response, unwrapping the application data
// from the API response payload.
function handleSuccess( response ) {
return( response.data );
}
the getUserStat() function will return json back.
here is my controller
UserService.getUserStat($scope.user_id).then(function(data){
alert("Result: " + JSON.stringify(data));
});
in my control I just show the json.
I build this code to my iPhone and test it over WIFI network, everything work fine. If i update the serverside, UserService.getUserStat in controller will show update. but the problem is when I test it on 3G network, iPhone always show the old json returned from the server (even I change server side data).
any idea to solve this problem?
Thank you
I had a similar problem when I tried to upload a camera photo to my data server.when i tested the app on my local WIFI it worked perfectly but when I tested it outside i noticed it fails to upload the file. eventualy the problem was that since the internet outside is much slower the app moved to another view without finish the upload action.
so for example if your controller looks something like this:
.controller('Ctrl1', function(webService, $scope, $state) {
UserService.getUserStat($scope.user_id).then(function(data){
alert("Result: " + JSON.stringify(data));
});
$state.go('app.posts');
});
it should be like this:
.controller('Ctrl1', function(webService, $scope, $state) {
UserService.getUserStat($scope.user_id).then(function(data){
alert("Result: " + JSON.stringify(data));
})
.finally(function() {
$state.go('app.posts');
});
});
