Pass array of data from Angular $http POST

问题:

I need to pass an array of object from my Angular application to a .Net web service with Nancy framework.

I tried this :

function TestCtrl($scope, $http){
    $scope.postTest = function(){

        var data = [obj1, obj2, obj3];

        $http({
            url: 'myURL',
            method: "POST",
            data: data,
            headers: {
                     'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
            }
        }).success(function(data){
            alert("done");
        });
    }
}

But server send 500 Internal server error.
I don't know why it doesn't work. I'm not an expert web service expert but I think it's a serialization problem.

Can someone help me?

回答1:

According to this post, you're right, this is about serialization. Angular doesn't automatic serialize the data for you, you need to parse the data before sending it:

...

$http({
  url: 'myURL',
  method: "POST",
  data: $.param(data),
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
  }
})...

If you don't use jQuery, you'll need to roll your own $.parse. There is a snippet here or you could adapt jQuery implementation.

回答2:

angular.toJson(data)

should work in place of

$.param(data)

回答3:

fauverism is right, you can use angular.toJson(data). Not instead, but before $.param though.

function TestCtrl($scope, $http){
$scope.postTest = function(){

    var data = [obj1, obj2, obj3];
    var jsonData=angular.toJson(data);
    var objectToSerialize={'object':jsonData};

    $http({
        url: 'myURL',
        method: "POST",
        data: $.param(objectToSerialize),
        headers: {
                 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
        }
    }).success(function(data){
        alert("done");
    });
}

}

回答4:

you can use $httpParamSerializer or $httpParamSerializerJQLike

$http(
    url: 'myURL',
    method: "POST",
    data: $httpParamSerializer(data),
)
