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

本文关键字：gt Forbidden Delete WCF Method REST | 更新日期: 2023-09-27 18:15:35

我正在从WCF REST服务执行GET、POST和DELETE操作。While GET &POST工作正常，DELETE不工作

从我的客户端应用程序，当我试图调用删除它说下面的错误。Error Message: The remote server returned an Error: (403) Forbidden.

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;
}

你能指出我错在哪里吗?

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

我会尝试将SetEntitySetAccessRule设置为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;
        }
    }

我最近有什么似乎是相同的问题，这是由于WebDAV拦截请求。删除该应用程序的模块解决了问题。

在IIS 7中:

<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中:

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