Question

我正在将wcf Rest服务用于Angular JS Application。我创建了几种方法来执行操作。首先，我有类库项目的wcf服务，我创建了另一个wcf服务项目来在本地IIS中托管它。当我在本地主机上运行wcf服务时它工作正常，但问题是当我输入方法名称时它会引发url，它会抛出未找到End point的异常。例如http://localhost:52098/HalifaxIISService.svc/GetCustomers//错误未找到终点。

这是我的界面..

  [OperationContract]

        [WebInvoke(Method = "POST",
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json,
        UriTemplate = "/GetCustomers")]
        string GetCustomers(string prefix);

        [OperationContract]
       [WebInvoke(Method = "POST",
       RequestFormat = WebMessageFormat.Json,
       ResponseFormat = WebMessageFormat.Json,
       UriTemplate = "/GetAccountDetails")]
        bool GetAccountDetails(string Account_Number);

这是类库项目中的app.cong文件。

这是IIS的service.svc代码。

这是.svc文件的web.config ..

这是屏幕截图。我已经在web.config文件中定义了终点。我想知道我得到了这个错误，没有找到终点。

Answer 1

您收到“找不到端点”错误，因为您已定义HTTP Post 端点。因此，您无法在Web浏览器中测试它们，因为它会发送HTTP 获取请求。

如果您希望在不编写任何代码的情况下测试您的服务，请使用Fiddler's Composer功能发送HTTP Post请求。

Fiddler Screenshot

或者更改WebInvoke属性以允许HTTP Get请求。

[WebInvoke(Method = "GET",
  RequestFormat = WebMessageFormat.Json,
  ResponseFormat = WebMessageFormat.Json,
  UriTemplate = "/GetCustomers")]

Answer 2

您无法尝试使用Post方法

Wcf服务无法在本地主机上找到端点
