【问题描述】：
我在Mediafire developers 部分阅读了很多内容，但似乎没有为 C# 开发人员提供库，所以我尝试使用他们的 Web 服务 API
上传文件的正常场景如下：
1- 通过此链接请求session_token
https://www.mediafire.com/api/user/get_session_token.php?email={0}&password={1}&application_id={2}&signature={3}&token_version=2
这一步工作正常，我得到session_token
之后，您在 post 请求中使用 session_token 通过此链接上传文件
http://www.mediafire.com/api/unversioned/upload/simple.php?uploadkey={0}&session_token={1}
Mediafire 文档描述 Raw HTTP Request 用于上传：
POST http://www.mediafire.com/api/unversioned/upload/simple.php?uploadkey=5bb66g94blnnk&session_token=aa22f5a968f827daf69fd6b3515110c43e036bc5d2ed8b81657dd1bdfe4b4c3e3ea6757d1f47bc3d6a001a16bc6f25abb486c5e779328a5769bd9ed6064edb69 HTTP/1.1

我尝试做HttpWebRequest，但它不起作用
byte[] postData = File.ReadAllBytes(@"img2.jpg");
System.Net.ServicePointManager.Expect100Continue = false;
System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)WebRequest.Create("http://www.mediafire.com/api/1.1/upload/upload.php?uploadkey=3kh445&session_token=" + respon.session_token);
request.Method = "POST";
request.Headers.Clear();
request.UserAgent = "User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0";
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
request.Headers.Add(HttpRequestHeader.AcceptLanguage, "en-us,en;q=0.5");
request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip,deflate");
request.ContentType = "multipart/form-data";
request.ContentLength = postData.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(postData, 0, postData.Length);
requestStream.Flush();
requestStream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
此代码抛出异常：
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF
我也尝试了这段代码，它的保留请求没有响应：
string path = String.Format("http://www.mediafire.com/api/unversioned/upload/simple.php?uploadkey=3kh5656&session_token={0}", respon.session_token);
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
string http = string.Format(
@"

,
path,
GetFileHash(@"img2.jpg"),
file.Length,
file.LongLength,
filename,
Encoding.Default.GetString(file),
DateTime.Now.Ticks.ToString("x")
);
sock.Connect(new IPAddress(Dns.GetHostEntry("www.mediafire.com").AddressList[0].GetAddressBytes()), 80);
sock.Send(Encoding.Default.GetBytes(http));
while (sock.Available == 0)
Thread.Sleep(1);
file = new byte[sock.Available];
sock.Receive(file, 0, sock.Available, SocketFlags.None);
string result = Encoding.ASCII.GetString(file);
sock.Close();
抱歉英语不好有不清楚的地方请告诉我我会编辑问题。

根据错误，调试您的
http字符串并确保您的换行符是\r\n而不仅仅是\r。
