WCF REST => Method = Delete =>（403）Forbidden

我从我的WCF REST服务执行GET，POST和DELETE操作。虽然GET & POST工作正常，但DELETE无法正常工作。WCF REST => Method = Delete =>（403）Forbidden

从我的客户端应用程序，当我尝试呼叫删除它说下面的错误。 错误消息：远程服务器返回错误：（403）禁止。

我的代码：

数据合同：

[WebInvoke(Method = "DELETE", UriTemplate = "users/", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] 
[OperationContract] 
string DeleteUser(UserInfo userinfo);

实现：

public string DeleteUser(UserInfo userinfo) 
{ 
    string sResult = ""; 

    try 
    { 
     UserDataAccess dataAccess = new UserDataAccess(); 

     sResult = dataAccess.DeleteUser(userinfo.GEId); 
    } 
    catch (Exception ex) 
    { 
     oLog.LogError(ex, true); 
     sResult = ex.Message; 
    } 

    return sResult; 
}

消费代码：

protected void btDeleteAsJson_Click(object sender, EventArgs e) 
{ 
    UserInfo user = new UserInfo(); 

    user.GEId = Convert.ToInt32(txtGEID.Text); 

    JavaScriptSerializer jsSerializer = new JavaScriptSerializer(); 
    string output = jsSerializer.Serialize(user); 

    SendMessageDeleteJson(apiUrl, output); 
} 

public void SendMessageDeleteJson(string endPoint, string output) 
{ 
    string data = output; 

    byte[] bytes = Encoding.UTF8.GetBytes(data); 

    HttpWebRequest request = CreateWebRequest1(endPoint, bytes.Length, "application/json"); 

    using (var requestStream = request.GetRequestStream()) 
    { 
     requestStream.Write(bytes, 0, bytes.Length); 
    } 

    using (var response = (HttpWebResponse)request.GetResponse()) 
    { 
     if (response.StatusCode != HttpStatusCode.OK) 
     { 
      string message = String.Format("DELETE failed. Received HTTP {0}", response.StatusCode); 
      throw new ApplicationException(message); 
     } 

     Stream responseStream = response.GetResponseStream(); 
     StreamReader reader = new StreamReader(responseStream); 
     string sResponseStream = reader.ReadToEnd(); 

     lblDeleteSuccess.Text = "Success! User has beed deleted"; 
    } 
} 

private HttpWebRequest CreateWebRequest1(string endPoint, Int32 contentLength, string ContentType) 
{ 
    var request = (HttpWebRequest)WebRequest.Create(endPoint); 

    request.Method = "DELETE"; 
    request.ContentLength = contentLength; 
    //request.ContentType = "application/x-www-form-urlencoded"; 
    request.ContentType = ContentType; 

    return request; 
}

你能指点我哪里错了吗？

我最近有什么似乎是相同的问题，这是由于WebDAV拦截请求。为该应用程序卸下模块解决了该问题。

在IIS 7：

<system.webServer> 
    <modules runAllManagedModulesForAllRequests="true"> 
    <remove name="WebDAVModule" /> 
    <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> 
    </modules> 
</system.webServer>

在IIS 6：

<system.web> 
    <httpModules> 
    <remove name="WebDAVModule" /> 
    <!-- ... --> 
    </httpModules> 
</system.web>

对不起，这个选项没有解决我的问题。仅供参考，我正在使用IIS 6.0。当我搜索论坛时，此解决方案适用于IIS 7.0 – user1059567

您是否尝试过与IIS 6等效？（我编辑了我的答案来添加它） – madd0

最后，我通过在网站上添加请求过滤来解决此问题，以允许DELETE动词 – user1059567

我想尝试SetEntitySetAccessRule到ALLREAD，AllWrite，或其他选项：

public class WcfDataService1 : DataService<HenryContext> 
    { 
     // This method is called only once to initialize service-wide policies. 
     public static void InitializeService(DataServiceConfiguration config) 

     {    

       config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); 

      config.SetServiceOperationAccessRule("*", ServiceOperationRights.All); 
      config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3; 
     } 
    }
