Question

我正在尝试向Android发出 httpsost 请求 WCF Restful service 。我在android中生成 XML 并通过httppost将其传递给服务。但是我一直得到上面指定的例外。

我使用 POST 方法创建了一个WCF Rest服务，该方法包含一个读取收到的xml内容的函数。

此外，我已在防火墙下的WWW中启用域。如果使用网址 http://192.168.0.12/RestFul/service1.svc ，我可以浏览该服务，但是当我尝试使用来自Android的服务（例如http://192.168.0.12/RestFul/service1.svc/Push）调用网络方法时，我会收到此异常

这是我的代码fofr makinh Httppost请求：

DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance();
                 dbfac.setNamespaceAware(true);
                 DocumentBuilder docBuilder = null;
                 try {
                    docBuilder = dbfac.newDocumentBuilder();
                } catch (ParserConfigurationException e) {

             }
             catch (Exception ex)
             {
             ex.printStackTrace();
             }

这是我的网络服务方法：

[OperationContract]
        [WebInvoke(Method = "POST", UriTemplate = "Push",
               RequestFormat = WebMessageFormat.Xml,
               ResponseFormat = WebMessageFormat.Xml,
               BodyStyle = WebMessageBodyStyle.Bare)]
        XElement DoWork(Stream xml);

public XElement DoWork(Stream xml)
        {
            StreamReader reader = null;
            XDocument xDocRequest = null;
            string strXmlRequest = string.Empty;
            reader = new StreamReader(xml);
            strXmlRequest = reader.ReadToEnd();
            xDocRequest = XDocument.Parse(strXmlRequest);
            string response = "<Result>OK</Result>";
            return XElement.Parse(response);
        }
