HTTP发布内容长度错误 [英] HTTP post contentlength error
问题描述
我有一个脚本发送多部分的哑剧,即带有附件的肥皂.我正在使用C#httpWebRequest类.我收到一条错误消息,指出内容长度是必需的,但是我正在使用webrequest的contentLength属性在代码中动态设置内容长度.任何想法为什么会这样?谢谢! 这是代码:
I have a script sending a multi part mime ie a a soap with attachments. I am using C# httpWebRequest class. I am getting an error that says the content length is required yet I am setting the content length dynamically in my code using webrequest's contentLength property. any ideas why this could be? thanx! this is the code:
public void sendSOAPoverHttpVoda()
{
try
{
string xmlDoc = this.soapXml;
byte[] bytes;
bytes = Encoding.UTF8.GetBytes(xmlDoc);
long contentSize = bytes.Length;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(conectionUrl);
req.SendChunked = true;
CredentialCache credentialCacheObj = new CredentialCache();
credentialCacheObj.Add(
new Uri(conectionUrl),
"Basic", new NetworkCredential("dddfff", "dddddd"));
credentialCacheObj.Add(new Uri(conectionUrl), "Digest", new NetworkCredential("dddfff", "dddddd"));
req.Credentials = credentialCacheObj;
req.Method = "POST";
req.ProtocolVersion = HttpVersion.Version11;
req.ContentLength = xmlDoc.Length;
req.ContentType = "multipart/related; boundary=\"----=cellsmart_mm7_SOAP\";type=\"text/xml\";Start=\"</cellsmart_mm7_submit>\"";
req.AllowWriteStreamBuffering = true;
req.Timeout = 20000;
req.Headers.Add("SOAPAction", "");
//req.Connection = "";
if (bytes != null)
{
using (Stream outputStream = req.GetRequestStream())
{
outputStream.Write(bytes, 0, xmlDoc.Length);
}
}
using (HttpWebResponse response = (HttpWebResponse)req.GetResponse())
{
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
string responseText = reader.ReadToEnd();
Console.WriteLine("Response received from URI : " + responseText);
Console.ReadLine();
}
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine("Error : " + ex.Message + "\n" + ex.StackTrace);
Console.ReadLine();
}
}
我得到的错误/异常是密码长度要求(411)
The error/exception i get is COntent length required (411)
推荐答案
您不能同时使用SendChunked = true和ContentLength.最简单的方法是使用分块响应并省略ContentLength.如果需要,您还可以保留ContentLength并省略SendChunked.
You can't use both SendChunked=true and ContentLength. The easiest thing to do would be to use a chunked response and omit the ContentLength. You could also retain the ContentLength and omit the SendChunked if you want though.
如果您不熟悉它,Wikipedia会提供漂亮的分块描述.
In case you're not familiar with it, wikipedia has a nice description of chunking.
