我正在尝试使用 wcf Rest 服务检索 Angular JS 应用程序中的单个记录。我在 google chrome 中检查了控制台窗口。我收到以下错误..
Failed to load resource: the server responded with a status of 404 (Not Found)
这是界面..
[OperationContract]
[WebInvoke(Method = "GET",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/AccountBalanceCheek")]
AccountBalanceRequest AccountBalanceCheek(AccountBalanceRequest accountNumber);
这是实现。
public AccountBalanceRequest AccountBalanceCheek(AccountBalanceRequest accountNumber)
{
using (SqlConnection conn = new SqlConnection(ConnectionString))
{
conn.Open();
var cmd = new SqlCommand("SELECT * FROM Current_Account_Details WHERE Account_Number = '" + accountNumber.Account_Number + "'", conn);
cmd.CommandType = CommandType.Text;
var reader = cmd.ExecuteReader();
//read the result of the execute command.
while (reader.Read())
{
//assuming that your property is the same as your table schema. refer to your table schema Current_Account_Details
accountNumber.Account_Number= reader["Account_Number"].ToString();
accountNumber.Account_Creation_Date = reader["Account_Creation_Date"].ToString();
accountNumber.Account_Type = reader["Account_Type"].ToString();
accountNumber.Branch_Sort_Code = reader["Branch_Sort_Code"].ToString();
accountNumber.Account_Fees = reader["Account_Fees"].ToString();
accountNumber.Account_Balance = reader["Account_Balance"].ToString();
accountNumber.Over_Draft_Limit = reader["Over_Draft_Limit"].ToString();
}
return accountNumber;
}
}
这是我的脚本代码..
var app = angular.module("WebClientModule", [])
.controller('Web_Client_Controller', ["$scope", 'myService', function ($scope, myService) {
var Id = $scope.Account_Number;
$scope.search = function (Id) {
var promiseGetSingle = myService.getbyId(Id);
promiseGetSingle.then(function (pl) {
var res = pl.data;
$scope.Account_Number = res.Account_Number;
$scope.Account_Creation_Date = res.Account_Creation_Date;
$scope.Account_Type = res.Account_Type;
$scope.Branch_Sort_Code = res.Branch_Sort_Code;
$scope.Account_Fees = res.Account_Fees;
$scope.Account_Balance = res.Account_Balance;
$scope.Over_Draft_Limit = res.Over_Draft_Limit;
// $scope.IsNewRecord = 0;
},
function (errorPl) {
console.log('failure loading Employee', errorPl);
});
}
}]);
app.service("myService", function ($http) {
this.getbyId = function (Id) {
return $http.get("http://localhost:52098/HalifaxIISService.svc/AccountBalanceCheek" + Id);
};
})
这是 html。

最佳答案
如果您收到 404 not font 错误，则意味着您的端点地址有问题。首先尝试使用 fiddler 或 postman 使用您的服务，并确保您的服务成功加载。然后跟踪您的 Angular 请求以确保您的客户端代码有效。
