Question

我正在努力学习一些或多或少的基础知识......关于在我的WebApi2 SPA应用程序中调用休息服务。

所以..基本上我正在尝试做的事情（首先作为一个例子），用两个字符串调用服务：用户名和密码。

这是WebService（asp.net中的UserController.cs）

public HttpResponseMessage Get(string username, string password)
    {
        var authUser = ControllerBasePage.UserServices.AuthenticateUser(username, password);
        if (authUser != null)
        {
            return Request.CreateResponse(HttpStatusCode.OK, authUser);
        }
        throw new HttpResponseException(HttpStatusCode.NotFound);
    }

以下是角度工厂和用法：

angular.module('photoAppLogin')
.factory('dataFactory', ['$http', function ($http) {
var urlBase = 'api/';
var dataFactory = {};

dataFactory.getUser = function (username, password) {
    var config = {
        url: urlBase + "user",
        params: { username: username, password: password }
    };

    //return $.post(urlBase + "user", { username: username, password: password });
    return $.ajax.get(config);
};

return dataFactory;
}]);

并且......控制器动作：

angular.module("photoAppLogin").controller('mainController',
function ($scope, dataFactory) {

    $scope.loggedInUser;
    $scope.status;

// create a message to display in our view
$scope.message = 'Loginform here !';

$scope.LoginUser = function () {
    var uname = $scope.Username;
    var pw = $scope.Pass;

    dataFactory.getUser(uname, pw)
        .success(function(usr) {
            $scope.loggedInUser = usr;
            $.cookie('loggedInUser', uname);
        })
        .error(function(error) {
        $scope.status = "User not found" + error.message;
    });
}
});

我能够获得一个空的GET服务，但我无法获得具有两个参数的服务。我已经尝试了两个帖子和获取（!!!）但似乎无法直接得到这个......

这是我得到的（唯一）错误：

TypeError: undefined is not a function

    at Scope.$scope.LoginUser (<http-localhost-here>/loginscripts.js:36:21)

    at HTMLButtonElement.n.event.add.r.handle (<http-localhost-here>/Scripts/jquery-2.1.1.min.js:3:3179) angular.js:9778

使用两个参数（用户名和密码）调用REST服务。未定义不是一个函数（Get？Post？）
