tee*_*bot 5 .net c# httphandler filestream
我正在尝试将块中的文件发送到HttpHandler但是当我在HttpContext中收到请求时,inputStream为空.
所以a:发送时我不确定我的HttpWebRequest是否有效而b:收到时我不知道如何在HttpContext中检索流
任何帮助非常感谢!
这是我如何从客户端代码提出我的请求:
private void Post(byte[] bytes)
{
HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://localhost:2977/Upload");
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.SendChunked = true;
req.Timeout = 400000;
req.ContentLength = bytes.Length;
req.KeepAlive = true;
using (Stream s = req.GetRequestStream())
{
s.Write(bytes, 0, bytes.Length);
s.Close();
}
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
}

这就是我在HttpHandler中处理请求的方式:
public void ProcessRequest(HttpContext context)
{
Stream chunk = context.Request.InputStream; //it's empty!
FileStream output = new FileStream("C:\\Temp\\myTempFile.tmp", FileMode.Append);
//simple method to append each chunk to the temp file
CopyStream(chunk, output);
}

我怀疑您将其作为表单编码上传可能会令人困惑。但这不是您要发送的内容(除非您掩盖了某些内容)。MIME 类型真的正确吗?
数据有多大?您需要分块上传吗?有些服务器可能不喜欢在单个请求中这样做;我很想通过WebClient.UploadData.
