AngularJs POST request for json not working

Question

Hi i tried POST json data in two ways its response in null

    var jsonData = $scope.addedCat; 
    console.log(jsonData);
    var request = $http({
        method:"POST",
        url:base_url+"Category_controller/json_test",
        data: JSON.stringify(jsonData),
        dataType: "application/json"
    });
    request.success(
    function(response){
         console.log(response);
    });

var cat_j = $scope.addedCat;
var data = $.param({ json:JSON.stringify(cat_j)});
$http.post(base_url+"Category_controller/json_test/",data).success(function(data, status) {
      console.log(data);
      console.log(status);
    })

How we decode the json data in php. I tried like this in Codeignitor framework.

    $cjson = $this->input->post('jsonData');
    $cat_json = json_decode($cjson);
    echo json_encode($cat_json);

On your server php file , try that instead, and you get the parametes passed from client:

//get parameters 
$params = json_decode(file_get_contents('php://input'), true); //read values from angular directive

Superglobal $_post only support application/x-www-form-urlencoded and multipart/form-data-encoded.

For application/json you should use php://input which can give you the raw bytes of the data. Here is a sample code of how to get the input data:

// get the raw POST data

$rawData = file_get_contents("php://input");

// this returns null if not valid json

print_r(json_decode($rawData));

$data = json_decode(file_get_contents('php://input'), true);

and do $data['jsonData'] now this $data['jsonData'] === $this->input->post('jsonData');
