如何使用ftp服务器上传文件？

Question

我有一个主机为我的网站和这个主机没有足够的空间来存放我的文件，我得到另一个主机来保存我的文件在这个主机上我有ftp地址和用户名和密码

我发现这段代码

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm");
        request.Method = WebRequestMethods.Ftp.UploadFile;

        // This example assumes the FTP site uses anonymous logon.
        request.Credentials = new NetworkCredential ("anonymous","janeDoe@contoso.com");

但

我怎样才能上传我的文件到另一个主机与ftp和获得url位置的保存文件？

Answer 1

您可以选择上传到ftp的路径，将目录附加到FTP地址：

string CompleteDPath = "ftp://yourFtpHost/folder1/folder2/";

string FileName = "yourfile.txt";

这里有一个我曾经找到的工作示例：

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