.NET处理请求后返回XML，为什么返回的XML带有处理页的HTML代码，如何处理？

Banianer 2012-03-12 04:34:36

为做数据接口，发送XML请求至一个处理页面 ReOnly.aspx
ReOnly.aspx 前台页面为默认创建的内容
cs代码如下：



public partial class ReOnly : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

            //设置 HTTP 头

            //Response.ContentType = "text/xml";

            //Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");

            Response.Clear();

            XmlTextWriter writer = null;

            writer = new XmlTextWriter(Response.Output);

            writer.Formatting = Formatting.Indented;

            writer.WriteStartDocument();

                writer.WriteStartElement("root");

                    writer.WriteStartElement("appid");

                    writer.WriteString("aaa");

                    writer.WriteEndElement();



                    writer.WriteStartElement("status");

                    writer.WriteString("0");

                    writer.WriteEndElement();



                    writer.WriteStartElement("needcookie");

                    writer.WriteString("2");

                    writer.WriteEndElement();



                writer.WriteEndElement();

            writer.WriteEndDocument();

        }

    }

请求的主要内容如下：



WebRequest request = WebRequest.Create(url);

                request.Method = "POST";

                string sendData = xmlDoc.InnerXml;

                byte[] byteArray = Encoding.Default.GetBytes(sendData);



                Stream dataStream = request.GetRequestStream();

                dataStream.Write(byteArray, 0, byteArray.Length);

                dataStream.Close();



                WebResponse response = request.GetResponse();

                dataStream = response.GetResponseStream();

                StreamReader reader = new StreamReader(dataStream, System.Text.Encoding.GetEncoding("GB2312"));

                string responseXml = reader.ReadToEnd();



                //try

                //{

                    xml.LoadXml(responseXml);//这里提示了错误，说DTD内容应该在写根节点前，原因主要是返回了多余的html代码

                    string status = xml.DocumentElement.SelectSingleNode("status").InnerText;

                    if (status == "0")

                    {

                        Message = "返回成功！";

                    }

                    else

                    {

                        Message = "请求数据错误！";

                    }

xml.LoadXml 得到的代码



<?xml version="1.0" encoding="utf-8"?>

<root>

  <appid>aaa</appid>

  <status>0</status>

  <needcookie>2</needcookie>

</root>



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">



<html xmlns="http://www.w3.org/1999/xhtml">

<head><title>



</title></head>

<body>

    <form name="form1" method="post" action="ReOnly.aspx" id="form1">

<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwULLTE2MTY2ODcyMjlkZLqex1hYqVDdvl7couz8D8g1tCTz" />



    <div>

    

    </div>

    </form>

</body>

</html>

我看把多余的 ReOnly.aspx 的 html 代码也给返回回来了，请问在返回XML 的时候要如何避免返回HTML 代码的内容呢？

谢谢！

总不会是让我吧 responseXml 中 </root> 后面的字符截掉吧~~

我想应该可以只返回XML的内容。

writer.WriteEndElement();

writer.WriteStartElement("status");
writer.WriteString("0");
writer.WriteEndElement();

writer.WriteStartElement("needcookie");
writer.WriteString("2");
writer.WriteEndElement();

writer.WriteEndElement();
writer.WriteEndDocument();
Response.End();
}
}

要不用ashx文件
