Question

我有一个.NET项目，它通过HTTP POST以SOAP对象的形式将数据发布到外部Web服务器。这是使用HttpWebRequest对象完成的。我从Web服务器得到一个响应，我用HttpWebResponse对象捕获它。此响应对象也是由SOAP信封包围的XML。

问题是，当我接收响应并将其输出到带有ToString的屏幕时，它显然会核对所有标签，并将它们全部组合成一个字符串。

如何在不删除所有XML格式/标签的情况下从Web服务器输出返回的XML？

以下是我正在使用的代码：

public static XmlDocument PostXMLTransaction(string v_strURL, XmlDocument v_objXMLDoc, string SoapAction, string username, string password)
    {
XmlDocument XMLResponse = null;
HttpWebRequest objHttpWebRequest;
HttpWebResponse objHttpWebResponse = null;

Stream objRequestStream = null;
Stream objResponseStream = null;

XmlTextReader objXMLReader;
objHttpWebRequest = (HttpWebRequest)WebRequest.Create(v_strURL);

try
{
    byte[] bytes;
    bytes = System.Text.Encoding.ASCII.GetBytes(v_objXMLDoc.InnerXml);
    objHttpWebRequest.Method = "POST";
    objHttpWebRequest.ContentLength = bytes.Length;
    objHttpWebRequest.ContentType = "text/xml; encoding='utf-8'";
    objHttpWebRequest.Headers.Add("SOAPAction", "Some URL/"+SoapAction);

    NetworkCredential nc = new NetworkCredential(username, password);

    objHttpWebRequest.Credentials = nc;

    objRequestStream = objHttpWebRequest.GetRequestStream();
    objRequestStream.Write(bytes, 0, bytes.Length);
    objRequestStream.Close();

    objHttpWebResponse = (HttpWebResponse)objHttpWebRequest.GetResponse();

    if (objHttpWebResponse.StatusCode == HttpStatusCode.OK)
    {
        objResponseStream = objHttpWebResponse.GetResponseStream();
        objXMLReader = new XmlTextReader(objResponseStream);

        XmlDocument xmldoc = new XmlDocument();
        xmldoc.Load(objXMLReader);
        XMLResponse = xmldoc;
        objXMLReader.Close();
    }
        objHttpWebResponse.Close();
        }
        catch (Exception we)
        {
            //TODO: Add custom exception handling
            throw new Exception(we.Message);
        }

        finally
        {
            //Close connections
            objRequestStream.Close();
            objResponseStream.Close();
            objHttpWebResponse.Close();

            //Release objects
            objXMLReader = null;
            objRequestStream = null;
            objResponseStream = null;
            objHttpWebResponse = null;
            objHttpWebRequest = null;
        }

        //Return
        return XMLResponse;
    }

我得到的反应如下。 Soap envelop只有xml标签，其他字母带有不同的字符。

 <?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><ns1:getHotelDetail xsi:type="xsd:string" xmlns:ns1="http://axis.frontend.hydra.hotelbeds.com">&lt;HotelDetailRS xmlns="http://www.hotelbeds.com/schemas/2005/06/messages" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.hotelbeds.com/schemas/2005/06/messages HotelDetailRS.xsd" echoToken="DummyEchoToken"&gt;&lt;AuditData&gt;&lt;ProcessTime&gt;570&lt;/ProcessTime&gt;&lt;Timestamp&gt;2015-03-20 07:50:07.272&lt;/Timestamp&gt;&lt;RequestHost&gt;54.169.51.224&lt;/RequestHost&gt;&lt;ServerName&gt;FORM&lt;/ServerName&gt;&lt;ServerId&gt;FO&lt;/ServerId&gt;&lt;SchemaRelease&gt;2005/06&lt;/SchemaRelease&gt;&lt;HydraCoreRelease&gt;2015.01.14&lt;/HydraCoreRelease&gt;&lt;HydraEnumerationsRelease&gt;N/A&lt;/HydraEnumerationsRelease&gt;&lt;MerlinRelease&gt;0&lt;/MerlinRelease&gt;&lt;/AuditData&gt;&lt;Hotel xsi:type="ProductHotel"&gt;&lt;Code&gt;52317&lt;/Code&gt;&lt;Name&gt;Hampton Inn &amp;amp; Suites Montreal&lt;/Name&gt;&lt;DescriptionList&gt;&lt;Description type="HotelDescription" languageCode="ENG" languageName="Ingles"&gt;where sophistication and culture meet...welcome to the Hampton Inn &amp;amp; Suites by Hilton Montreal (Dorval).

Answer 1

输出正确，你的响应实际上是一个字符串，而字符串又是xml里面的。 getHotelDetail响应是一个有效的字符串对象。您可能必须从getHotelDetail字符串内容创建另一个XmlDocument。

我相信这是Web Service内部的东西，其中响应是Xml DataSet而不是XmlDocument。

但是，为什么不简单地从添加服务引用中导入Web服务而不是手动获取Web服务响应，.NET完全支持自动获取和编组对正确对象的响应。

Httpwebrequest给出响应删除所有XML格式/标签
