Angular REST cannot return simple data - angularjs

I am trying to get a $http REST GET call working in my Appgyver project working but nothing I do seems to come right, always returns an error.
Please note the angular app will be running on mobile devices eventually and then connect to my remote web service.
I've double checked that my custom API is working and returning data correctly in a number of ways, namely:
hard coded cUrl request running from sh files in terminal - Returns data and correct 200 code
Tested the API end points in both POSTMAN and Firefox's SOA client.
Putting in my test end point of http://somesite.com/quote-and-buy-performance/druidapi/taxonomy_term returns data as below:
[{"tid":"1","vid":"2","name":"ACME Ltd.","description":"","format":"filtered_html","weight":"0","parent":"0","uri":"http://somesite.com/quote-and-buy-performance/druidapi/taxonomy_term/1"},{"tid":"2","vid":"2","name":"ABC Films LTD","description":"","format":"filtered_html","weight":"0","parent":"0","uri":"http://somesite.com/quote-and-buy-performance/druidapi/taxonomy_term/2"}]
Even a simple CSRF Token request gives me errors.
Could someone possibly point out where I am going wrong here, the Appgyver site is badly documented and I have tried the Angular RESTful sample which my code below is based upon from https://docs.angularjs.org/api/ng/service/$http and https://docs.angularjs.org/api/ng/service/$http#setting-http-headers
Please note the code below is basically Angular.js using Javascript syntax (as opposed to Coffeescript), logging output follows the code
angular
.module('main')
.controller('LoginController', function($scope, supersonic, $http) {
$scope.navbarTitle = "Settings";
$scope.stoken = "Response goes here";
$scope.processLogin = function(){
var csrfToken;
steroids.logger.log("START CALL: processLogin");
// $form_login_email_address = $scope.login_email;
// $form_login_password = $scope.login_password;
$local_get = "http://somesite.com/quote-and-buy-performance/services/session/token";
$hal_get_taxterm_index = "http://somesite.com/quote-and-buy-performance/druidapi/taxonomy_term";
// $http.defaults.headers.common.contentType('application/json');
var req = {
method: 'GET',
url: $hal_get_taxterm_index,
headers: {
'Content-Type': 'application/json'
}
}
$http(req)
.success(function(data, status, headers) {
steroids.logger.log("Inside http.get() success");
}).error(function(data, status, headers){
steroids.logger.log("Inside http.get() WITH ERROR");
steroids.logger.log('data: ' + data);
steroids.logger.log('status: ' + status);
}).then(function(data, status, headers){
steroids.logger.log("Inside http.get() then");
});
steroids.logger.log("END CALL: processLogin");
}
});
Logging output from calls to steroids.logger.log
View Time Level Message
main#login 16:01:55.219 info "Inside http.get() WITH ERROR"
main#login 16:01:55.219 info "data: null"
main#login 16:01:55.219 info "status: 0"
main#login 16:01:55.64 info "END CALL: processLogin"
main#login 16:01:55.64 info "START CALL: processLogin"

Here's what I would do:
Separate out your http call into a service. This is a pretty standard way to modularize your code in angular:
angular.module('main').factory("SomeService", function($http) {
return {
get: function() {
$http({
url: "http://somesite.com/quote-and-buy-performance/druidapi/taxonomy_term",
method: "GET",
headers: {
"Content-Type": "application/json"
}
}).success(function(data, status, headers, config) {
console.log("Success!");
console.log(data);
}).error(function(data, status, headers, config) {
console.log("Error!");
console.log(status);
console.log(data);
});
}
}
})
Then to use this in your controller, just include it in your controller declaration and call get like you would a normal method:
angular.module('main').controller('LoginController', function($scope, supersonic, SomeService) {
$scope.navbarTitle = "Settings";
$scope.stoken = "Response goes here";
$scope.processLogin = function(){
var csrfToken;
steroids.logger.log("START CALL: processLogin");
SomeService.get();
steroids.logger.log("END CALL: processLogin");
}
})
Do this and then comment back with your results and we can work from there.

If your angular's app is within a certain domain, then HTTP request must be made within the same domain.
In your case, you are trying a cross domain request (a request on another domain). You must then make a cross domain request.
You can see this question.
The author uses $http.jsonp() to send cross domain requests. There migth be another way to do it.

Retrieve a Sharepoint List with Angular JS

I have created an Angular JS application which would output a list of data in a Share Point list. I am trying to make a rest API call to my Share Point List to get the data, however I am unable to do it as I get an error 403 Forbidden.
Below is my controller which tries to fetch the data.
app.controller('RetrieveRecords', function ($q, $http, $scope) {
var url = "https://testapp.sharepoint.com/sites/testmyapplication/_api/web/lists/getByTitl
e('TestAppList')/items?$select=Status,Time";
$http(
{
method: "GET",
url: url,
headers: { "accept": "application/json;odata=verbose" }
}
).success(function (data, status, headers, config) {
$scope.details = data.d.results;
}).error(function (data, status, headers, config) {
});
});
My Angular JS application is not a Share Point page, my application is basically hosted as a Azure Static Website. I checked some online tutorials, however I couldn't find a solution to the problem I am facing.
Thank you.
#John,
You have to supply digest within the header.
You will find the necessary value in the element called '__REQUESTDIGEST'. So with jQuery you can get the value like this: $('#__REQUESTDIGEST').val().
This value needs to be added to the header:
headers: { "Accept": "application/json;odata=verbose", "X-RequestDigest": $('#__REQUESTDIGEST').val() }
can you try adding this tag and see if it works.
Hope it helps.

Angularjs - 500 (Internal Server Error) on $http Post

I am new to Ionic and angular. I am building a sample with ionic framework using angular.js. I want to call WebApi through $http post method. I checked this(ionic-proxy-example) solution and I am trying to implement the same using my api. When I call the api provided in above example in my sample project, I get the records but its not working with my api. It throws 500 internal error.
Here is my app.js
angular.module('myApp', ['myApp.controllers', 'myApp.services'])
.constant('ApiEndpoint', {url: 'http://localhost:8100/api'})
Services.js
angular.module('myApp.services', [])
.factory('Api', function($http, $q, ApiEndpoint) {
console.log('ApiEndpoint', ApiEndpoint)
var getApiData = function() {
var q = $q.defer();
var data = {
Gameweek_ID: '179',
Vender_ID: '1',
Language:'en'
};
var config = {
headers : {
"Content-Type": "application/json; charset = utf-8;"
}
};
$http.post(ApiEndpoint.url, data, config)
.success(function (data, status, headers, config) {
// $scope.PostDataResponse = data;
alert('success');
console.debug("response :" + data);
q.resolve(data);
})
.error(function (data, status, header, config) {
// $scope.ResponseDetails = "Data: " + data +
alert('error');
console.debug("error :" + data);
q.reject(data);
});
return q.promise;
}
return {getApiData: getApiData};
})
controllers.js
angular.module('myApp.controllers', [])
.controller('Hello', function($scope, Api) {
$scope.employees = null;
Api.getApiData()
.then(function(result)
{console.log("result is here");
jsonresponse = result.data;
$scope.employees = jsonresponse;}
)
});
And Ionic.Project File
{
"name": "Multilingual",
"app_id": "4b076e44",
"proxies": [
{
"path": "/api",
"proxyUrl": ""
}
]}
I am trying to understand the problem and checked multiple methods to call the api. Surprisingly, it works with ajax post call without any CORS errors. As I am using Angular, I am trying to get this done through $http post. I feel it is some minor issue but I am not able to figure out. Will be grateful for solutions. Thank you.
You've set the content type to json so the sever is expecting a json string but isn't receiving a properly formatted json string as you're sending through an object and hence the error.
Where you have $http.post(ApiEndpoint.url, data, config) change it to $http.post(ApiEndpoint.url, JSON.stringify(data), config).
If that doesn't work, change your content type to application/x-www-form-urlencoded and update this line $http.post(ApiEndpoint.url, data, config) to $http.post(ApiEndpoint.url, $httpParamSerializer(data), config) , don't forget to inject the $httpParamSerializer function.
The problem is that you are sending a POST with $http.post request instead of a GET request with $http.get
Try as below-
$http({
url: ApiEndpoint.url,
method: "POST",
data: data,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).Success(..rest code goes here..)
In WebAPI, when we pass more than one object in POST method, we get 500 internal error and hence we use ViewModel in such scenarios(talking about asp.net MVC).

angular laravel nginx 400 Bad Request

Help, I've got 400 error on POST and or PUT method, but GET works just fine,
I'm using angular as front end and laravel as API, my server is using nginx,
I've used CORS and I everything works fine on my local vagrant which is running on apache.
I'm sure I have my route set correctly, here's some of it from the module I use:
Route::group(array('prefix'=>'/api', 'middleware' => 'cors'),function(){
Route::post('/create_level', 'LevelController#store');
Route::get('/read_level', 'LevelController#index');
Route::get('/read_level/{id}', 'LevelController#show');
Route::put('/read_level/{id}', 'LevelController#update');
Route::delete('/read_level/{id}', 'LevelController#destroy');
here's part of my angular service:
app.service("edulevelService", function ($http, $q, $rootScope)
{
edu.updateEdulevel = function(id, edu){
var deferred = $q.defer();
$http.put($rootScope.endPoint + 'read_level/'+ id, edu)
.success(function(res)
{
deferred.resolve(res);
})
.error(function(err, stat){
deferred.reject(err);
console.log('error code: Ser-UEDU');
});
return deferred.promise;
}
edu.createEdulevel = function(edu){
var deferred = $q.defer();
$http.post($rootScope.endPoint + 'create_level', edu)
.success(function(res)
{
deferred.resolve(res);
})
.error(function(err, stat){
deferred.reject(err);
console.log('error code: Ser-CEDU');
});
return deferred.promise;
}
....
oh I forgot to mention different method cause different error code POST cause 405, PUT cause 400, and I've tried using Postman:
POST is working using text type and return 405 using application/json,
but when I tried
PUT method even though it return 200 I only got NULL data entered to my db (text type), and if I use application/json it return 400
Please Help
Finally found solution:
change $http.post to:
$http({
method: "post",
url: $rootScope.endPoint + 'create_level',
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: $.param({ .... })
})
somehow it works, exept on my login page which using stellizer to do post method and i can't find how should I change it without breaking all the function...
any one?
I only need to add:
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
and
data: $.param({ ...... })

Requesting data to Sharepoint 2013 using rest api service to integrate with angular app

I am learning sharepoint 2013 for a required incoming project. I has never worked on .net or any other ms technology so i would appreciate if the answers are dumb proof.
I have a server that is running sharepoint 2013 and iis v8.0
Currently i am having some issues, but the main one is that i am trying to access the api service from an angular application. I setted the mapping for intranet to the ip of the server and i can access the api through to the web browser.
I also setted the http response headers to "Access-Control-Allow-Origin" : * in iis. However when i try to access the api using the angular $http object i am getting a message that says XMLHttpRequest cannot load http://x.x.x.x/_api/web. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http:// localhost : 9000' is therefore not allowed access. The response had HTTP status code 401.
The idea is that the angular application is totally independant of sharepoint and any .net technology. All i want to do is use the rest api to get/edit data.
The request i am making looks like this:
angular.module('angYeoman2App')
.factory('SharePointJSOMFactory', function SharePointJSOMFactory($http, $q) {
var deffered = $q.defer();
var data = [];
var myService = {};
SharePointJSOMFactory.getTasksRESTAppWeb = function() {
var restQueryUrl = "http://x.x.x.x/_api/web";
$http({
headers: { 'Accept': 'application/json; odata=verbose' },
method: 'GET',
url: restQueryUrl
})
.success(function(data, status, headers, config){
console.log(data);
deffered.resolve();
})
.error(function(data, status, headers, config){
console.log('error', data)
deffered.resolve();
});
return deffered.promise;
};
SharePointJSOMFactory.data = function() {
return data;
};
return SharePointJSOMFactory;
});
Any idea what i am doing wrong? I has read that i need to add <% Response.AddHeader("Access-Control-Allow-Origin", "*") %> somewhere, but i don't have any idea to what file.
I also have another problem (not so relevant at this point): When i try to access to a subsite using the ip address it seems it is applying the theme of the parent and it doesn't load the content of the subsite. Any idea why?
Any help is welcome. Tks for your time, have a nice day.

Getting JSON data using Angular JS's $http service

I need to get JSON data from a server with URL :
http://xxxx.xxxx.xxxx.xxxx:8084/inpulse/api/user/listall
Here's my angular code:
var app = angular.module('app',[]);
app.controller('Controller', function ($scope,$http) {
$scope.email="";
$scope.password="";
$scope.sample="";
$http({
method: 'GET',
url: 'http://xxxx.xxxx.xxxx.xxxx/inpulse/api/user/listall',
})
.success(function (data, status, headers, config) {
var ret = data;
$scope.sample = JSON.stringify(ret);
})
.error(function (data, status, headers, config) {
alert(status);
// something went wrong :(
});
});
Now the same code worked when i used a JSON test URL like http://ip.jsontest.com/.
Its Definitely not a problem with the server because I tested it with a REST client and got a response. I can't figure out what I'm doing wrong.
It might be a CORS configuration issue.
If you are trying to access the server from a page that is not in the same domain/origin, you'll get an error because the server is not configured to allow CORS.
The error reported by Chrome looks like this:
XMLHttpRequest cannot load http://xxxx.xxxx.xxxx.xxxx/inpulse/api/user/listall. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://fiddle.jshell.net' is therefore not allowed access.
Other than that the code seems to work just as expected.
