[jquery] from jquery $.ajax to angular $http

I have this piece of jQuery code that works fine cross origin:

jQuery.ajax({
    url: "http://example.appspot.com/rest/app",
    type: "POST",
    data: JSON.stringify({"foo":"bar"}),
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function (response) {
        console.log("success");
    },
    error: function (response) {
        console.log("failed");
    }
});

Now I'm tring to convert this to Angular.js code without any success:

$http({
    url: "http://example.appspot.com/rest/app",
    dataType: "json",
    method: "POST",
    data: JSON.stringify({"foo":"bar"}),
    headers: {
        "Content-Type": "application/json; charset=utf-8"
    }
}).success(function(response){
    $scope.response = response;
}).error(function(error){
    $scope.error = error;
});

Any help appreciated.

You may use this :

Download "angular-post-fix": "^0.1.0"

Then add 'httpPostFix' to your dependencies while declaring the angular module.

Ref : https://github.com/PabloDeGrote/angular-httppostfix

you can use $.param to assign data :

 $http({
  url: "http://example.appspot.com/rest/app",
  method: "POST",
  data: $.param({"foo":"bar"})
  }).success(function(data, status, headers, config) {
   $scope.data = data;
  }).error(function(data, status, headers, config) {
   $scope.status = status;
 });

look at this : AngularJS + ASP.NET Web API Cross-Domain Issue

We can implement ajax request by using http service in AngularJs, which helps to read/load data from remote server.

$http service methods are listed below,

 $http.get()
 $http.post()
 $http.delete()
 $http.head()
 $http.jsonp()
 $http.patch()
 $http.put()

One of the Example:

    $http.get("sample.php")
        .success(function(response) {
            $scope.getting = response.data; // response.data is an array
    }).error(){

        // Error callback will trigger
    });
