ASP.NET ProtocolViolationException - 无法发送内容体与这个动词型 [英] ASP.NET ProtocolViolationException - Cannot send a content-body with this verb-type

问题描述

为什么会 req.GetRequestStream（）关闭（）; 的原因。 ProtocolViolationException - 无法发送内容体与这个动词型在code段是从这里。谢谢你。

  WebRequest的REQ = NULL;
        WebResponse类RSP = NULL;
        尝试
        {
            字符串文件名=Login.xml;
            字符串URI =HTTP：//本地主机/ API /登录;
            REQ = WebRequest.Create（URI）;            //req.Proxy = WebProxy.GetDefaultProxy（）; //启用如果使用代理
            req.Method =POST; // Post方法
            req.Co​​ntentType =文/ XML; // 内容类型            //使用基于文本的作家包裹请求流
            StreamWriter的作家=新的StreamWriter（req.GetRequestStream（））;            //写XML文本流
            writer.WriteLine（this.GetTextFromXMLFile（文件名））;
            writer.Close（）;            //将数据发送到Web服务器
            RSP = req.GetResponse（）;        }
        赶上（WEBEX引发WebException）
        {
            LOG.Error（webEx.StackTrace.ToString（））;
        }
        赶上（异常前）
        {
            LOG.Error（ex.StackTrace.ToString（））;
        }
        最后
        {
            。如果（！REQ = NULL）req.GetRequestStream（）关闭（）;
            如果（RSP！= NULL）rsp.GetResponseStream（）关闭（）。
        }
 

解决方案

您是否尝试过使用 req.Co​​ntentType =应用程序/ XML 而不是正文/ XML ？

Why will req.GetRequestStream().Close(); cause "ProtocolViolationException - Cannot send a content-body with this verb-type." The code snippet is from here. Thanks.

        WebRequest req = null;
        WebResponse rsp = null;
        try
        {
            string fileName = "Login.xml";
            string uri = "http://localhost/api/login";
            req = WebRequest.Create(uri);

            //req.Proxy = WebProxy.GetDefaultProxy(); // Enable if using proxy
            req.Method = "POST";        // Post method
            req.ContentType = "text/xml";     // content type

            // Wrap the request stream with a text-based writer
            StreamWriter writer = new StreamWriter(req.GetRequestStream());

            // Write the XML text into the stream
            writer.WriteLine(this.GetTextFromXMLFile(fileName));
            writer.Close();

            // Send the data to the webserver
            rsp = req.GetResponse();

        }
        catch (WebException webEx)
        {
            LOG.Error(webEx.StackTrace.ToString());
        }
        catch (Exception ex)
        {
            LOG.Error(ex.StackTrace.ToString());
        }
        finally
        {
            if (req != null) req.GetRequestStream().Close();
            if (rsp != null) rsp.GetResponseStream().Close();
        }

解决方案

Have you tried using req.ContentType = application/xml instead of text/xml?
