我需要在服务器上上传文件(具有不同的扩展名,即 .txt、.jpg、.pdf ......)。我创建了一个接受 http 请求的站点,并将虚拟目录映射到物理目录。所有这些在下载中都可以正常工作,现在我必须实现上传。
这是我的代码
private void UploadFile(string uploadFileName, string localFileName)
{
//long length = 0;
string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");
HttpWebRequest httpWebRequest2 = (HttpWebRequest)WebRequest.Create(uploadFileName);
httpWebRequest2.ContentType = "multipart/form-data; boundary=" + boundary;
httpWebRequest2.Method = "POST";
httpWebRequest2.KeepAlive = true;
httpWebRequest2.Credentials = new NetworkCredential("USER", "PASSWORD", "DOMAIN");
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}";
memStream.Write(boundarybytes, 0, boundarybytes.Length);
string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n Content-Type: application/octet-stream\r\n\r\n";
string header = string.Format(headerTemplate, "uplTheFile", localFileName);
byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);
memStream.Write(headerbytes, 0, headerbytes.Length);
FileStream fileStream = new FileStream(localFileName, 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();
//error returned in lenght field: "This stream does not support seek operations."
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();
//error returned from getResponse: "The remote server returned an error: (405) Method Not Allowed."
//I guess cause my folder is in read only
Stream stream2 = webResponse2.GetResponseStream();
StreamReader reader2 = new StreamReader(stream2);
MessageBox.Show(reader2.ReadToEnd());
webResponse2.Close();
httpWebRequest2 = null;
webResponse2 = null;
}
首先我得到这个错误:远程服务器返回一个错误:(405)方法不允许。所以我尝试通过在网站上添加映射来启用 POST。
现在在 te 服务器上的文件夹中,我有一个 web.config 文件,即:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<directoryBrowse enabled="true" />
<handlers>
<add name="File TXT" path="*.*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\System32\inetsrv\asp.dll" resourceType="Unspecified" requireAccess="Script" preCondition="bitness64" />
</handlers>
</system.webServer>
</configuration>
这样我没有收到任何错误,但应用程序没有上传任何文件。我该如何解决这个问题?
