问题描述

我想将文件从一台服务器上传到另一台 FTP 服务器，以下是我上传文件的代码，但它抛出错误:

I want to upload file from one server to another FTP server and following is my code to upload file but it is throwing an error as:

远程服务器返回错误:(550) 文件不可用(例如，找不到文件，无法访问).

The remote server returned an error: (550) File unavailable (e.g., file not found, no access).

这是我的代码:

string CompleteDPath = "ftp URL";
string UName = "UserName";
string PWD = "Password";
WebRequest reqObj = WebRequest.Create(CompleteDPath + FileName);
reqObj.Method = WebRequestMethods.Ftp.UploadFile;
reqObj.Credentials = new NetworkCredential(UName, PWD);
FileStream streamObj = System.IO.File.OpenRead(Server.MapPath(FileName));
byte[] buffer = new byte[streamObj.Length + 1];
streamObj.Read(buffer, 0, buffer.Length);
streamObj.Close();
streamObj = null;
reqObj.GetRequestStream().Write(buffer, 0, buffer.Length);
reqObj = null; 

你能告诉我哪里出错了吗?

Can you please tell me where i am going wrong?

推荐答案

请确保您的ftp路径设置如下.

Please make sure your ftp path is set as shown below.

string CompleteDPath = "ftp://www.example.com/wwwroot/videos/";

string FileName = "sample.mp4";

WebRequest reqObj = WebRequest.Create(CompleteDPath + FileName);

以下脚本非常适合我通过 ftp 将文件和视频上传到另一个服务器.

The following script work great with me for uploading files and videos to another servier via ftp.

FtpWebRequest ftpClient = (FtpWebRequest)FtpWebRequest.Create(ftpurl + "" + username + "_" + filename);
ftpClient.Credentials = new System.Net.NetworkCredential(ftpusername, ftppassword);
ftpClient.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
ftpClient.UseBinary = true;
ftpClient.KeepAlive = true;
System.IO.FileInfo fi = new System.IO.FileInfo(fileurl);
ftpClient.ContentLength = fi.Length;
byte[] buffer = new byte[4097];
int bytes = 0;
int total_bytes = (int)fi.Length;
System.IO.FileStream fs = fi.OpenRead();
System.IO.Stream rs = ftpClient.GetRequestStream();
while (total_bytes > 0)
{
   bytes = fs.Read(buffer, 0, buffer.Length);
   rs.Write(buffer, 0, bytes);
   total_bytes = total_bytes - bytes;
}
//fs.Flush();
fs.Close();
rs.Close();
FtpWebResponse uploadResponse = (FtpWebResponse)ftpClient.GetResponse();
value = uploadResponse.StatusDescription;
uploadResponse.Close();
