Question

您好我是Web API的新手，我正在使用AngularJS和Web API我正在尝试将图像上传到Web API但是当我点击按钮发送图像时它会给我一个错误

我已经使用了GET方法，它向我展示了该Web API中的所有图像，但它不适用于方法POST

这是我的代码

的index.html

MarcaJson.js

var app = angular
    .module("MarcasApp", [])
    .controller("MarcaController", function($scope, $http){
        $scope.getTodos =function(){
            var apiUrl = 'http://tiendawebapi.azurewebsites.net/api/marcas/';
            $http.get(apiUrl).then(function(response){
            $scope.marcas =  response.data;
            });
        };

        $scope.btnGuardar = function(){
            var datos = {
                id: $scope.txtId,
                imagen: $scope.getTheFiles
            }

            var apiUrl = 'http://tiendawebapi.azurewebsites.net/api/marcas/';
            $http.post(apiUrl, JSON.stringify(datos)).then(function(response){
                if  (response.statusText == Created){
                    $scope.msgGuardar = "Marca Guardada";
                }
            }, function(error){
                $scope.msgGuardar = "Ocurrio un error " + error.statusText;
            });
        };
    });
