I m 从事GET、POST和DELETE业务,来自我的WCF REST服务。 虽然GET & POST运行良好,但DELETE没有发挥作用。

From my client application, when i try to call delete it says below error. Error Message: The remote server returned an error: (403) Forbidden.

<><>My Code:

<>Data合同:

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

<>执行>:

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;
}

www.un.org/Depts/DGACM/index_spanish.htm 消费法:

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;
}

Could you please point me where I m wrong?
