php server unable to recieve the json variable from angularjs using $.http().post request

Question

Iam doing a post request to a php script form my AngularJS for mobile app. when iam using this code form action="url" method="post" in html.its working fine. but when iam using ajax url request in angularjs , php server is not receiving the values.Then how can i achieve that

mycode:

var data: { jwt: '[email protected]' }

    var req={
      method : 'POST',
    url: 'http:url//'
    }

       $http(req).success(function(data){

    alert(JSON.stringify(data));

       }).error(function(data) {
        alert("failure");

    alert(JSON.stringify(data));


       });


 }

myphp code:

$id = $_POST["jwt"];

Answer 1

This is the incorrect way to use $http.post. It's just a wrapper for $http({}). What you actually want is either to just use $http({}) or use $http.post() accordingly:

$http.post(
    req.url,
    //your data
).then(successCallback, errorCallback);

Answer 2

this is th prefect solution. i got the answer

var app=angulamodule("myapp",[])
.config(function ($httpProvider){
$httpProvider.defaults.transformRequest = function(data){
        if (data === undefined) {
            return data;
        }
        return serialize(data);
    };  
 $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';
})


var serialize = function(obj, prefix) {
  var str = [];
  for(var p in obj) {
    if (obj.hasOwnProperty(p)) {
      var k = prefix ? prefix + "[" + p + "]" : p, v = obj[p];
      str.push(typeof v == "object" ?
        serialize(v, k) :
        encodeURIComponent(k) + "=" + encodeURIComponent(v));
    }
  }
  return str.join("&");
};

var req={ method : 'POST', url: 'http:url//' }

   $http(req).success(function(data){

alert(JSON.stringify(data));

   }).error(function(data) {
    alert("failure");

alert(JSON.stringify(data));


   });

}
