Question

我想尽量保持简单 -

- 我们从Godaddy windows托管切换到Godaddy linux托管

- 切换后，当我从c＃使用POST时，我得到内部服务器错误500 程序（紧凑框架）与内容类型 - multipartformdata，但是，我仍然可以使用服务器上的普通html表单发布，没有任何问题。

- 切换之前一切都工作得很好！我仍然可以做GET请求，甚至是来自我的C＃app的正常（非multipart / form-data）POST请求。

请求/响应中的标头和内容，使用以下代码：

请求标题 -

POST /users/test.php HTTP/1.1
Content-Type: multipart/form-data; boundary=----------------------------8d0cb969d25c418
Host: mydomain(i censor)
Content-Length: 403
Expect: 100-continue
Connection: Keep-Alive

请求内容 -

------------------------------8d0cb969d25c418
Content-Disposition: form-data; name="title";

test
------------------------------8d0cb969d25c418
Content-Disposition: form-data; name="pwd";

testpwd
------------------------------8d0cb969d25c418
Content-Disposition: form-data; name="file"; filename=test.txt
 Content-Type: text/html

testfile
------------------------------8d0cb969d25c418

回复标题 -

HTTP/1.1 500 Internal Server Error
Date: Fri, 20 Dec 2013 10:32:01 GMT
Server: Apache mod_fcgid/2.3.10-dev
Content-Length: 662
Keep-Alive: timeout=5
Connection: Keep-Alive
Content-Type: text/html; charset=iso-8859-1

这是我的C＃代码（注意 - 我必须只使用紧凑框架）：

openFileDialog1.ShowDialog();
NameValueCollection formsdata = new NameValueCollection();
formsdata.Add("title", textBox3.Text);
formsdata.Add("pwd", textBox4.Text);
string[] names = new string[1] { openFileDialog1.FileName };
UploadFilesToRemoteUrl("http://mydomain/users/writefile.php", names,    "notused", formsdata, openFileDialog1.SafeFileName);

以及方法UploadFilesToRemoteUrl -

        public static void UploadFilesToRemoteUrl(string url, string[] files, string
logpath, NameValueCollection nvc, string filename)
        {

            long length = 0;
            string boundary = "----------------------------" +
            DateTime.Now.Ticks.ToString("x");


            HttpWebRequest httpWebRequest2 = (HttpWebRequest)WebRequest.Create(url);
            httpWebRequest2.ContentType = "multipart/form-data; boundary=" +
            boundary;
            httpWebRequest2.Method = "POST";
            httpWebRequest2.KeepAlive = true;
            httpWebRequest2.Credentials =
            System.Net.CredentialCache.DefaultCredentials;



            Stream memStream = new System.IO.MemoryStream();

            byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" +
            boundary + "\r\n");


            string formdataTemplate = "\r\n--" + boundary +
            "\r\nContent-Disposition: form-data; name=\"{0}\";\r\n\r\n{1}";

            foreach (string key in nvc.Keys)
            {
                string formitem = string.Format(formdataTemplate, key, nvc[key]);
                byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(formitem);
                memStream.Write(formitembytes, 0, formitembytes.Length);
            }


            memStream.Write(boundarybytes, 0, boundarybytes.Length);

            string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=" + filename + "\r\n Content-Type: text/html\r\n\r\n";

            for (int i = 0; i < files.Length; i++)
            {

                //string header = string.Format(headerTemplate, "file" + i, files[i]);
                string header = string.Format(headerTemplate, "file", files[i]);

                byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);

                memStream.Write(headerbytes, 0, headerbytes.Length);


                FileStream fileStream = new FileStream(files[i], FileMode.Open,
                FileAccess.Read);
                byte[] buffer = new byte[1024];

                int bytesRead = 0;

                while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
                {
                    memStream.Write(buffer, 0, bytesRead);

                }


                memStream.Write(boundarybytes, 0, boundarybytes.Length);


                fileStream.Close();
            }

            httpWebRequest2.ContentLength = memStream.Length;

            Stream requestStream = httpWebRequest2.GetRequestStream();

            memStream.Position = 0;
            byte[] tempBuffer = new byte[memStream.Length];
            memStream.Read(tempBuffer, 0, tempBuffer.Length);
            memStream.Close();
            requestStream.Write(tempBuffer, 0, tempBuffer.Length);
            requestStream.Close();


            WebResponse webResponse2 = httpWebRequest2.GetResponse();

            Stream stream2 = webResponse2.GetResponseStream();
            StreamReader reader2 = new StreamReader(stream2);


            MessageBox.Show(reader2.ReadToEnd());

            webResponse2.Close();
            httpWebRequest2 = null;
            webResponse2 = null;
        }

非常感谢任何帮助！
