如何避免非常长的querystring值出现服务器错误414

webrequest c#

我有一个项目需要在网页上发布250万个字符的查询字符串。服务器本身只分析了5400个字符或更少的URI。在为webrequest/webresponse、webclient和sockets尝试了几组不同的代码之后,我终于找到了解决我的问题的以下代码:

HttpWebRequest webReq;
HttpWebResponse webResp = null;
string Response = "";
Stream reqStream = null;
webReq = (HttpWebRequest)WebRequest.Create(strURL);

Byte[] bytes = Encoding.UTF8.GetBytes("xml_doc=" + HttpUtility.UrlEncode(strQueryString));
webReq.ContentType = "application/x-www-form-urlencoded";
webReq.Method = "POST";
webReq.ContentLength = bytes.Length;
reqStream = webReq.GetRequestStream();
reqStream.Write(bytes, 0, bytes.Length);
reqStream.Close();
webResp = (HttpWebResponse)webReq.GetResponse();

if (webResp.StatusCode == HttpStatusCode.OK)
{
     StreamReader loResponseStream = new StreamReader(webResp.GetResponseStream(), Encoding.UTF8);
     Response = loResponseStream.ReadToEnd();
}

webResp.Close();
reqStream = null;
webResp = null;
webReq = null;
