WCF REST JSON服務返回錯誤404 /例外：System.Web.HttpException（0x80004005）

Question

我跟着這個例子，使我的第一個WCF服務：WCF REST Service JSON，然後編輯它來創建我自己的。我能夠讓我的服務在使用ASP.NET Developer Server進行調試時運行良好。我打開了端口8081（在服務器，防火牆和路由器上），然後將其分配給IIS中的「註冊」文件夾。然後，我花了一天的時間找出我必須使用MsDeployAgentService後，將服務發佈到運行IIS 6的Windows Server 2003。然後我使用IIS將ASP.NET版本設置爲4.0.3019。註冊文件夾包含Service1.svc，Web.config和bin文件夾。

這是我的網絡配置文件：

    </system.serviceModel> 
    <system.webServer> 
    <modules runAllManagedModulesForAllRequests="true"/> 
    </system.webServer> 
</configuration> 

當我嘗試使用了測試客戶端的服務，我得到錯誤404用下面的語句

byte[] data = client.DownloadData("http://ServerIP:8081/Registration/Service1.svc/CheckSoftware/1/Customer1/1_0/abc123/1/1"); 

當我刪除端口I得到一個錯誤401「未經授權」

byte[] data = client.DownloadData("http://ServerIP/Registration/Service1.svc/CheckSoftware/1/Customer1/1_0/abc123/1/1"); 

我已經嘗試使用LAN IP和WA N IP地址。

跟隨this post，因爲它看起來很喜歡OP遵循相同的例子，並有西米拉問題，但它沒有幫助。

我然後看着在事件查看器在服務器上，發現這個時候我包含在端口號：

WebHost failed to process a request. 
Sender Information: System.ServiceModel.Activation.HostedHttpRequestAsyncResult/23878916 
Exception: System.Web.HttpException (0x80004005): The service '/Registration/Service1.svc' does not exist. ---> System.ServiceModel.EndpointNotFoundException: The service '/Registration/Service1.svc' does not exist.

Process ID: 3460 

我可以清楚地看到Service1.svc文件存在文件夾中。我很迷茫，並希望得到任何幫助。

編輯，包括更多的代碼：

namespace ServiceApp 
{ 
    [ServiceContract] 
    public interface IService1 
    { 

     [OperationContract] 
     [WebInvoke(Method = "GET",

      RequestFormat = WebMessageFormat.Json, 
      ResponseFormat = WebMessageFormat.Json)] 
     SoftwareStatus CheckSoftware(string SoftwareID, string Version, string CustomerID, string Key, string moboID, string processorID); 

     [OperationContract] 
     [WebInvoke(
      Method = "GET",

      ResponseFormat = WebMessageFormat.Json)] 
     string SaveKey(string SoftwareID, string CustomerID, string Key, string moboID, string processorID);

Answer 1

當使用IIS 6.0作爲服務我不需要在URL中包含文件夾名稱。所以只需更改一行代碼即可解決我的問題。

byte[] data = client.DownloadData("http://ServerIP:8081/Service1.svc/CheckSoftware/1/Customer1/1_0/abc123/1/1"); 

Answer 2

是您的UriTemplate設置是否正確？ 404錯誤表明它根本沒有與服務/方法聯繫。

REST服務是簡單的Web的API，而不是試圖導入服務，就像您正常的WCF服務，嘗試一個普通的HTTP請求（只是一個光禿禿的例子，而不是解決方案）：

//declare the request (not sure of your uri, so i guessed) 
    var queryString = string.Format("1/{0}/1_0/{1}/1/1", Param1, Param2); 
    var req = 
     HttpWebRequest)WebRequest.Create("http://ServerIP:8081/Registration/Service1.svc/CheckSoftware/"); //base address of service 
    req.Method = "POST"; 
    req.ContentType = "application/x-www-form-urlencoded"; 

    //build the fields stream 
    var fields = Encoding.UTF8.GetBytes(queryString); 
    req.ContentLength = fields.Length; 

    //put the request info into the stream 
    var requestStream = req.GetRequestStream(); 
    requestStream.Write(fields, 0, fields.Length); 
    requestStream.Close(); 

    //execute the request 
    var resp = (HttpWebResponse)req.GetResponse(); 

    //pull your infos 
    var statusCode = (int)resp.StatusCode; 
    var body = new StreamReader(resp.GetResponseStream()).ReadToEnd();
