angular $http post not sending data for service - angularjs

Question

I´m trying user $http post in angular, where the rest service receive an object. The data is a Json where I need pass with parameter for method in service.
My angular code (it´s doesn´t work for me):
$http({
method:'POST',
url:request.url,
data: JSON.stringify(objcsr);
headers: {'Content-Type':'application/json; charset=utf-8'}
}).then(function(objS){
alert('Success :- '+JSON.stringify(objS));
},function(objE){
debugger;
alert('error:- '+JSON.stringify(objE));
});
If I comment the row data, the comunication with service it´s ok:
$http({
method:'POST',
url:request.url,
//data: JSON.stringify(objcsr);
headers: {'Content-Type':'application/json; charset=utf-8'}
}).then(function(objS){
alert('Success :- '+JSON.stringify(objS));
},function(objE){
debugger;
alert('error:- '+JSON.stringify(objE));
});
My method in service:
public UserAccessDTO Authenticate(AuthenticationDTO authentication)
{
.....
}

Answer 1

I hope the object you are passing in data parameter is same as AuthenticationDTO class, its properties must be same. If that is fine then try running this.
$http.post('url',JSON.stringify(data),{headers: {'Content-Type':'application/json'}})
.success(function (data) {
alert('Success :- '+JSON.stringify(data));
});
As well I am assuming that you have included [HttpPost] attribute before your method. like this:
[HttpPost]
public UserAccessDTO Authenticate(AuthenticationDTO authentication)
{
.....
}
