我需要通过 ftp 上传文件到主机。在主机根目录下创建的/home2/travele2
路径
我可以通过 FileZilla 程序将文件上传到主机,但是当我尝试通过网站上传文件时,出现以下错误:
The remote server returned an error: (550) File unavailable (e.g., file not found, no access).
问题是什么?
// Get the object used to communicate with the server.
FtpWebRequest ftpWebRequest = (FtpWebRequest)WebRequest.Create("ftp://00.00.00.00/home2/travele2");
ftpWebRequest.Method = WebRequestMethods.Ftp.UploadFile;
// This example assumes the FTP site uses anonymous logon.
ftpWebRequest.Credentials = new NetworkCredential("aaaaaaa", "0000000");
// Copy the contents of the file to the request stream.
StreamReader sourceStream = new StreamReader(Server.MapPath("/Content/Site.pdf"));
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
ftpWebRequest.ContentLength = fileContents.Length;
Stream requestStream = ftpWebRequest.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)ftpWebRequest.GetResponse();
Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);
response.Close();
最佳答案
URL 必须包含目标文件名:
string url = "ftp://ftp.example.com/home2/travele2/Site.pdf";
FtpWebRequest ftpWebRequest = (FtpWebRequest)WebRequest.Create(url);
FtpWebRequest
还怎么知道要使用什么名称?
一旦您解决了这个问题,您会发现上传会损坏文件,因为您将文件视为 UTF-8 编码的文本。废话,因为PDF是二进制文件。
有关正确的代码,请参阅:
