FtpWebResponse实现ftp文件上传碰到的小问题
FtpWebRequest上传文件报550错误按照一般的思路做两件事情
1.防火墙的设置，验证没有问题
2.权限设计,ftp的上传权限也没有问题
public string Put()
{
try
{
//
//打开上传文件
//
FileStream sourceStream = new FileStream(m_Filename, FileMode.Open);
FileInfo fileInf = new FileInfo(m_Filename);
//
//绑定Url 例如: ftp://host/path
//
UriBuilder ftpUri = new UriBuilder("ftp", m_Host);
if ((m_Destination == null) || (m_Destination.Length == 0))
{
ftpUri.Path = m_Filename;
}
else
{
ftpUri.Path = m_Destination + "/" + fileInf.Name;
}
//
//创建ftp连接
//
m_Ftp = (FtpWebRequest)WebRequest.Create(ftpUri.Uri);
m_Ftp.Method = WebRequestMethods.Ftp.UploadFile;
m_Ftp.UseBinary = m_UseBinary;
m_Ftp.UsePassive = m_UsePassive;
m_Ftp.Credentials = new NetworkCredential(m_Username, m_Password);
FtpWebResponse response = (FtpWebResponse)m_Ftp.GetResponse();
Console.WriteLine(response.BannerMessage);
ftpstring.AppendLine(response.BannerMessage);
Stream ftpStream = m_Ftp.GetRequestStream();
//
//读数据并写入FtpStream
//
int bufferSize = 8192;
int readCount;
byte[] buffer = new byte;
readCount = sourceStream.Read(buffer, 0, bufferSize);
while (readCount > 0)
{
ftpStream.Write(buffer, 0, readCount);
readCount = sourceStream.Read(buffer, 0, bufferSize);
}
//
//关闭FtpStream
//
sourceStream.Close();
ftpStream.Close();
//
//得到最终ftp结果
//
Console.WriteLine(response.StatusDescription);
ftpstring.AppendLine(response.StatusDescription);
response.Close();
return ftpstring.ToString();
}
catch (Exception ex)
{
Console.WriteLine("Exception during FtpPut Activity{0}{1}",
Environment.NewLine,
ex);
ftpstring.AppendLine("发送错误" + Environment.NewLine+ex.Message);
return ftpstring.ToString();
}
}
后来在微软的中文社区看到了如下代码
FileInfo fileInf = new FileInfo(filename);
string uri = "ftp://" + m_Host + "/" + m_Destination + "/" + fileInf.Name;
FtpWebRequest reqFTP;
// Create FtpWebRequest object from the Uri provided
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(
"ftp://" + m_Host + "/" + m_Destination + "/" + fileInf.Name));
// Provide the WebPermission Credintials
reqFTP.Credentials = new NetworkCredential(m_Username,
m_Password);
// By default KeepAlive is true, where the control connection is
// not closed after a command is executed.
reqFTP.KeepAlive = false;
// Specify the command to be executed.
reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
// Specify the data transfer type.
reqFTP.UseBinary = true;
// Notify the server about the size of the uploaded file
reqFTP.ContentLength = fileInf.Length;
// The buffer size is set to 2kb
int buffLength = 2048;
byte[] buff = new byte;
int contentLen;
// Opens a file stream (System.IO.FileStream) to read the file to be uploaded
FileStream fs = fileInf.OpenRead();
try
{
// Stream to which the file to be upload is written
Stream strm = reqFTP.GetRequestStream();
// Read from the file stream 2kb at a time
contentLen = fs.Read(buff, 0, buffLength);
// Till Stream content ends
while (contentLen != 0)
{
// Write Content from the file stream to the
// FTP Upload Stream
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLength);
}
// Close the file stream and the Request Stream
strm.Close();
fs.Close();
}
catch(Exception ex)
{
Console.WriteLine(ex.Message, "Upload Error");
}
}
想了一下终于明白了，原来FTP的目标路径要加入文件，想想也是，不然怎么建立文件流呢？
这段代码改成这样，哈哈ok了。
if ((m_Destination == null) || (m_Destination.Length == 0))
{
ftpUri.Path = m_Filename;
}
else
{
ftpUri.Path = m_Destination + "/" + fileInf.Name;
}
