Reference error while trying make call to different end points

I am trying to call a odata end Point and check the response and make a another call to different endpoint if the condition is not met. If I don’t have the condition and making just one call to just one end point it works, but below code is throwing Reference error even with the attempt to the first call
$scope.getRequest = function () {
var url = $rootScope.BaseURL;
var config = {
headers: {
'Authorization': `Basic ${$scope.key}`,
'Prefer': 'odata.maxpagesize=2000'
}
};
$http.get(url, config)
.then(
function (response) { // success async
$scope.viewRequest.data = response.data;
},
function (response) { // failure async
console.log("There was an error getting the request from CORE");
}
);
if (viewRequest.data.REV_SAMPLE_CMQREQUEST.length = 0) {
var url = $rootScope.BaseURL + `CMQ_REQUEST('${$scope.viewRequest.barcode}’)`;
var config = {
headers: {
'Authorization': `Basic ${$scope.key}`,
'Prefer': 'odata.maxpagesize=2000'
}
};
$http.get(url, config)
.then(
function (response1) { // success async
$scope.viewRequest1.data = response1.data;
},
function (response1) { // failure async
console.log("There was an error getting the request from CORE");
}
);
}
};
Below is the screenshot of the error
$scope.getRequest = function () {
var url = $rootScope.BaseURL;
var config = {
headers: {
'Authorization': `Basic ${$scope.key}`,
'Prefer': 'odata.maxpagesize=2000'
}
};
$http.get(url, config)
.then(function (response) { // success async
$scope.viewRequest.data = response.data;
},
function (response) { // failure async
console.log("There was an error getting the request from CORE");
}
)
.then(nextViewRequest);
};
var newViewRequest = function (response) {
var url1 = $rootScope.BaseURL + `CMQ_REQUEST('${$scope.viewRequest.barcode}')`;
if ($scope.viewRequest.data.REV_SAMPLE_CMQREQUEST.length = 0) {
return $http.get(url1, config)
.then(
function (response1) { // success async
$scope.viewRequest1.data = response1.data;
},
function (response1) { // failure async
console.log("There was an error getting the request from CORE");
}
);
}
return $q.reject({ message: 'Validations didnt work' });
};

You are making 2 request in parallel rather than wait for the first one to finish and then make the second one, also the code is hard to read. My guess is that the second response is not returning anything because the first condition is not met.
I recommend you to read about promises chaining and the $q service to make custom rejections or resolve promises in your scenarios to order this logic your code should like something like this:
$scope.getRequest = function () {
// setup url and config
$http.get(url, config)
.then(nextViewRequest) // the return of this function will override the next result of the next promise chaining
.then(function(response) {
$scope.viewRequest1.data = response.data;
});
};
var nextViewRequest= function(response) {
// validations necessary
if(valid) {
return $http.get(url, config);
}
// If conditions are not met, then you can use the $q service to create a rejection
return $q.reject({message: 'validations on second request failed'});
};

Angular JS catching server error Jsonp

I am trying to catch server error for eg 500 in my angular app. Unfortunately this construction fails:
return promise = this.httpService.jsonp("serverurl")
.success((response: any): ng.IPromise<any> => { return response.data; })
.error((response: any): ng.IPromise<any> => { return response.data; });
I want to catch server response - in this case simply the message. How to do this?

The $http service is a function which takes a single argument — a configuration object — that is used to generate an HTTP request and returns a promise.
// Simple GET request example:
$http({
method: 'GET',
url: '/someUrl'
}).then(function successCallback(response) {
// this callback will be called asynchronously
// when the response is available
console.log(response); // add console log of response
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
console.log(response); // add console log of error response
});
Or a interceptor can be used to "monitor" all http's:
// register the interceptor as a service
$provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
return {
// optional method
'request': function(config) {
// do something on success
return config;
},
// optional method
'requestError': function(rejection) {
// do something on error
if (response.status === 500) {
//DO WHAT YOU WANT
}
return $q.reject(rejection);
},
// optional method
'response': function(response) {
// do something on success
return response;
},
// optional method
'responseError': function(rejection) {
// do something on error
if (response.status === 500) {
//DO WHAT YOU WANT
}
return $q.reject(rejection);
}
};
});
$httpProvider.interceptors.push('myHttpInterceptor');

GET x-Auth-Token via JavaScript/Angular/Ionic Promise

I have a problem and don´t know how to solve it...
I have to authenticate a user in my IonicApp through a token based authentication. So i have to store the token inside the app, which shouldn´t be a problem...
The Problem is: How can i get the token?
Here´s my code:
// Alle Aufrufe an die REST-Api werden hier durchgeführt
var httpCall = {
async : function(method, url, header, params, data) {
// if (url != 'login') {
// header['X-Auth-Token'] = userTokenFactory.getUserToken();
// }
//console.log(header['X-Auth-Token']);
var ipurl = "IPURL";
// $http returns a promise, which has a then function, which also returns a promise
var promise = $http({
method : method,
url : ipurl + url,
//headers : header,
params : params,
data : data,
config : {
timeout : 5000
}
}).then(function successCallback(response) {
//console.log("data:" + response.data);
//console.log("header:" + response.headers);
console.log("token:" + response.headers['X-AUTH-TOKEN']);
//console.log(response.data.token);
console.log("token" + repsonse.token);
// TRY TO READ THE X_AUTH_TOKEN HERE !!!!!!!!!!!!
return response;
}, function errorCallback(response) {
return response;
});
// Return the promise to the controller
return promise;
}
};
return httpCall;
});
And here´s a picture of the Response from the Server (from Firefox). As you can see, the X-Auth-Token is there...
here´s the x-auth-token
Thanks for the help!!

There are lot of articles are available over handling authentication in AngularJS. This article is the one perfect suitable in your case.
So you can get token from your request as,
}).then(function successCallback(response) {
console.log("data:" + response.data);
$window.sessionStorage.token = response.data.token;
return response;
}, function errorCallback(response) {
return response;
});
Now we have the token saved in sessionStorage. This token can be sent back with each request by at least three ways
1. Set header in each request:
`$http({method: 'GET', url: url, headers: {
'Authorization': 'Bearer ' + $window.sessionStorage.token}
});`
2. Setting defaults headers
`$http.defaults.headers.common['X-Auth-Token'] = 'Bearer ' + $window.sessionStorage.token;`
3. Write Interceptor:
Interceptors give ability to intercept requests before they are
handed to the server and responses before they are handed over to the
application code that initiated these requests
myApp.factory('authInterceptor', function ($rootScope, $q, $window) {
return {
request: function (config) {
config.headers = config.headers || {};
if ($window.sessionStorage.token) {
config.headers.Authorization = 'Bearer ' + $window.sessionStorage.token;
}
return config;
},
response: function (response) {
if (response.status === 401) {
// handle the case where the user is not authenticated
}
return response || $q.when(response);
}
};
});
myApp.config(function ($httpProvider) {
$httpProvider.interceptors.push('authInterceptor');
});
Refer AngularJS $http guide for detailed explanation.
As you are getting response.data null and image demonstrates that headers are being returned, I would suggest you to check if you are getting data with
response.headers(),
if then try with response.headers()["X_AUTH_TOKEN"].

AngularJS HTTP interceptor

Using an interceptor in AngularJS how can console.log("finished AJAX request") when any request has completed?
I have been looking at interceptors and so far have the following but it fires on the start of the request not the end.
app.factory('myInterceptor', [function() {
console.log("finished AJAX request")
var myInterceptor = {
};
return myInterceptor;
}]);
config:
app.config(function ($stateProvider, $urlRouterProvider, $httpProvider) {
$httpProvider.interceptors.push('myInterceptor');
etc

You need to put the console in the response function of the httpInterceptor
// register the interceptor as a service
$provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
return {
// optional method
'request': function(config) {
// do something on success
return config;
},
// optional method
'requestError': function(rejection) {
// do something on error
if (canRecover(rejection)) {
return responseOrNewPromise
}
return $q.reject(rejection);
},
// optional method
'response': function(response) {
// do something on success
console.log('I am done');
return response;
},
// optional method
'responseError': function(rejection) {
// do something on error
if (canRecover(rejection)) {
return responseOrNewPromise
}
return $q.reject(rejection);
}
};
});
$httpProvider.interceptors.push('myHttpInterceptor');
Over here in the response method I have included the console log function call

Angular not getting response when it's a non-200

I've impelmented the httpInterceptor found here.
If my Basic Auth header has valid credentials, everything works fine, but if I get back a 401, then the application just hangs and I never receive a response.
Here's my interceptor:
angular.module('TDE').factory('httpInterceptor', function httpInterceptor ($q, $window, $location) {
return function (promise) {
var success = function (response) {
//window.logger.logIt("httpInterceptor received a good response: " + response);
return response;
};
var error = function (response) {
//window.logger.logIt("httpInterceptor received an error: " + response);
if (response.status === 401) {
$location.url('/login');
}
return $q.reject(response);
};
return promise.then(success, error);
};
});
Declaring the httpInterceptor in app.js
angular.module('TDE', []);
var TDE = angular.module('TDE', ['ux', 'ngRoute', 'ngResource', 'TDE', 'hmTouchEvents', 'infinite-scroll', 'ui.bootstrap', 'ui.sortable']);
TDE.config(['$routeProvider', '$locationProvider', '$httpProvider', function ($routeProvider, $locationProvider, $httpProvider) {
$httpProvider.responseInterceptors.push('httpInterceptor');
$routeProvider
.when('/', {})
.when('/login', { templateUrl: "Views/Login/login.html", controller: "LoginController" })
And my authenticate method
authenticate: function (user, password) {
// window.logger.logIt("serviceAccount: " + $rootScope.serviceAccount);
window.logger.logIt("In authenticate...");
var deferred = $q.defer();
var encoded = encoder.encode($rootScope.serviceAccount);
//var encoded = encoder.encode(user + ":" + password);
if (user && password) {
window.logger.logIt("We've got a username and password...");
$http.defaults.headers.common.Authorization = 'Basic ' + encoded;
sessionStorage.setItem('Authorization', $http.defaults.headers.common.Authorization);
var url = $rootScope.serviceBaseUrl + "login/authenticate";
window.logger.logIt(url);
$http({
method: "POST",
url: url,
data: {
"Username": user,
"Password": password,
"AccessToken": ""
},
headers: {
"Content-Type": "application/json"
}
})
.success(function (data, status, headers, config) {
window.logger.logIt("We've got a response (success)...");
if (data.IsAuthenticated) {
deferred.resolve(data);
session.setSession();
} else {
deferred.reject(status);
}
})
.error(function (data, status, headers, config) {
window.logger.logIt("We've got a response (error)...");
$dialogservice.showMessage("Authentication Error", "Return Code: " + status);
deferred.reject(status);
});
} else {
window.logger.logIt("We've got a response...");
deferred.reject(401);
}
return deferred.promise;
},
You'll see that in my Authenticate method, there are two lines that I'm testing:
var encoded = encoder.encode($rootScope.serviceAccount);
and
var encoded = encoder.encode(user + ":" + password);
We are REQUIRED to use Basic Authentication (which is over SSL). Right now, all I'm testing is that I can receive a 401 back. If I use the $rootScope.serviceAccount (which is working), I get a 200 response right away. But if I purposely send a bad username/password, I NEVER get a response, the application just sits there.
Edit: Ok, I've updated my code to the following, and still getting the same behavior:
angular
.module('TDE')
.config(['$httpProvider', function ($httpProvider) {
$httpProvider.interceptors.push(function ($q) {
return {
'request': function (config) {
window.logger.logIt("Request is being sent...");
var headers = config.headers;
if (!headers.Authorization) {
headers.Authorization = sessionStorage.getItem('Authorization');
}
return config || $q.when(config);
},
'response': function (response) {
window.logger.logIt("got a good response...");
return response;
},
'responseError': function (rejection) {
window.logger.logIt("responseError error...");
return $q.reject(rejection);
},
};
});
}]);

Well, again, PhoneGap is the issue!!!!!!!!!!!!!!!!!
Example 1
Example 2
Example 3
Example 4

Try this interceptor:
.factory('httpInterceptor', function(){
return {
request : function(yourRequestConfig){
var returnPromise = $q.defer();
$http(yourRequestConfig).then(function(response) {
console.log("successful response from server ", response);
returnPromise.resolve(response);
}, function(someReason) {
console.log("failure response from server", reason);
returnPromise.reject(reason);
});
return returnPromise.promise;
}
}
});
used as
httpInterceptor.request(request config).then(returnValue){
console.log('inside controller', returnValue);
});
where request config is something like:
var requestConfig = {
method: "GET",
url: "localhost:8080/getStuff"
};
