问题描述
我正在尝试在 FTP 服务器上创建一个文件，但我所拥有的只是一个字符串或数据流以及创建它时应使用的文件名.有没有办法从流或字符串在服务器上创建文件(我没有创建本地文件的权限)?
I'm trying to create a file on an FTP server, but all I have is either a string or a stream of the data and the filename it should be created with. Is there a way to create the file on the server (I don't have permission to create local files) from a stream or string?
string location = "ftp://xxx.xxx.xxx.xxx:21/TestLocation/Test.csv";
WebRequest ftpRequest = WebRequest.Create(location);
ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
ftpRequest.Credentials = new NetworkCredential(userName, password);
string data = csv.getData();
MemoryStream stream = csv.getStream();
//Magic
using (var response = (FtpWebResponse)ftpRequest.GetResponse()) { }
推荐答案
只需将你的流复制到 FTP 请求流:
Just copy your stream to the FTP request stream:
Stream requestStream = ftpRequest.GetRequestStream();
stream.CopyTo(requestStream);
requestStream.Close();
对于一个字符串(假设内容是一个文本):
For a string (assuming the contents is a text):
byte[] bytes = Encoding.UTF8.GetBytes(data);
using (Stream requestStream = request.GetRequestStream())
{
requestStream.Write(bytes, 0, bytes.Length);
}
或者甚至更好地使用 StreamWriter:
Or even better use the StreamWriter:
using (Stream requestStream = request.GetRequestStream())
using (StreamWriter writer = new StreamWriter(requestStream, Encoding.UTF8))
{
writer.Write(data);
}
如果内容是文本，则应使用文本模式:
If the contents is a text, you should use the text mode:
request.UseBinary = false;
