我必须使用HTTPS上传和下载FTP文件。 如果我正确思考,我必须使用HTTPWebRequest类,因为ftp使用的是HTTPS协议。通过https协议在安全FTP上传文件#
现在我试图下载一个文件,但是我得到的所有响应流只是登录的“虚拟用户'XXX'”。
可能是我没有设置正确的方法类型或其他错误。
WebRequest ftp1 = HttpWebRequest.Create(u1);
ftp1.PreAuthenticate = true;
ftp1.Credentials = netCred;
ftp1.Method = WebRequestMethods.Ftp.DownloadFile;
try
{
response = (HttpWebResponse)ftp1.GetResponse();
remoteStream = response.GetResponseStream();
localStream = File.Create("c:/TEST1.txt");
int bytesProcessed = 0;
byte[] buffer = new byte[4096];
int bytesRead;
do
{
// Read data (up to 1k) from the stream
bytesRead = remoteStream.Read(buffer, 0, buffer.Length);
// Write the data to the local file
localStream.Write(buffer, 0, bytesRead);
// Increment total bytes processed
bytesProcessed += bytesRead;
} while (bytesRead > 0);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
finally
{
// Close the response and streams objects here
// to make sure they're closed even if an exception
// is thrown at some point
if (response != null) response.Close();
if (remoteStream != null) remoteStream.Close();
if (localStream != null) localStream.Close();
}
你能把代码放在这里吗? – Turbot
我已添加基本代码。我刚刚开始了解它。 – user1810332
