我正在将 Wcf 服务消耗到 Angular Js 应用程序中。我在 wcf 服务中有一个 bool 函数来接受用户名和密码。我正在尝试使用 Angular Js 应用程序创建用户登录系统，但是当我输入正确的用户名和密码时，它无法按照我的预期工作。 Google Chrome 控制台窗口中没有显示任何错误。
这是界面。
[OperationContract]
[WebInvoke(Method = "POST",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
//BodyStyle = WebMessageBodyStyle.WrappedRequest,
UriTemplate = "/AuthenticateUser")]
bool AuthenticateUser(UserLogin userLogin);
这里是实现..
public bool AuthenticateUser(UserLogin userLogin)
{
// ConfigurationManager class is in System.Configuration namespace
string CS = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
// SqlConnection is in System.Data.SqlClient namespace
using (SqlConnection con = new SqlConnection(CS))
{
SqlCommand cmd = new SqlCommand("spAuthenticateUser", con);
cmd.CommandType = CommandType.StoredProcedure;
//Formsauthentication is in system.web.security
string encryptedpassword = FormsAuthentication.HashPasswordForStoringInConfigFile(userLogin.Password, "SHA1");
//sqlparameter is in System.Data namespace
SqlParameter paramUsername = new SqlParameter("@UserName", userLogin.Username);
SqlParameter paramPassword = new SqlParameter("@Password", encryptedpassword);
cmd.Parameters.Add(paramUsername);
cmd.Parameters.Add(paramPassword);
con.Open();
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
int RetryAttempts = Convert.ToInt32(rdr["RetryAttempts"]);
if (Convert.ToBoolean(rdr["AccountLocked"]))
{
return false;
}
else if (RetryAttempts > 0)
{
int AttemptsLeft = (4 - RetryAttempts);
//lblMessage.Text = "Invalid user name and/or password. " +
// AttemptsLeft.ToString() + "attempt(s) left";
}
else if (Convert.ToBoolean(rdr["Authenticated"]))
{
return true;
}
}
return false;
}
}
这是脚本代码。
///// <reference path="../angular.min.js" />
var app = angular.module("WebClientModule", [])
.controller('Web_Client_Controller', ["$scope", 'myService', function ($scope, myService) {
$scope.OperType = 1;
//1 Mean New Entry
//To Clear all input controls.
function ClearModels() {
$scope.OperType = 1;
$scope.Username = "";
$scope.Password = "";
}
$scope.login = function () {
var User = {
Username: $scope.Username,
Password: $scope.Password,
};
if ($scope.OperType === 1) {
var promisePost = myService.AuthenticateUser(User);
promisePost.then(function (pl) {
$scope.Id = pl.data.Id;
window.location.href = "/Welcome/Index";
ClearModels();
}, function (err) {
$scope.msg = "Password Incorrect !";
console.log("Some error Occured" + err);
});
}
};
}]);
app.service("myService", function ($http) {
// Create new record
this.AuthenticateUser = function (User) {
return $http.post("http://localhost:52098/HalifaxIISService.svc/AuthenticateUser", JSON.stringify(User));
}
})
这是 HTML 代码..

这是我运行应用程序时的屏幕截图。 
他将不胜感激任何帮助或建议。
最佳答案
我在 jsfiddle 中运行了您的示例以查看发生了什么，然后我更改了它:
<body ng-app="WebClientModule">
我添加了 ng-app 属性，现在可以正常工作了。
