c# HttpWebRequest.GetResponse() returned an error: (404) Not Found

Question

我有一个 Asp.net 控制台应用程序，我使用此代码上传文件：

byte[] buffer = memoryStream.ToArray();
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.ContentType = "application/octet-stream";
request.Method = "POST";
request.ContentLength = buffer.Length;
Stream dataStream = request.GetRequestStream();
dataStream.Write(buffer, 0, buffer.Length);
dataStream.Close();
response = (HttpWebResponse)request.GetResponse();

如果缓冲区大小为 8 MB，则 HttpWebResponse 工作完美，但如果缓冲区大小为 32 MB，则 request.GetResponse() 返回错误：

The remote server returned an error: (404) Not Found.

Answer 1

我想您尝试请求的 url 具有最大请求长度，不允许大长度的请求。

修改应该在目标服务或 url 中。配置文件修改：

<httpRuntime maxRequestLength="33554432" executionTimeout="300"/>
