Net::FTP#putbinaryfile(binary_file, remotefile) binary_file is not a local file from some directory,but a dynamic generation from codes. The above codes not work,how to write it to ftp? -- Posted via http://www.ruby-forum.com/.
ftp api itself has binary mode ,but not support writing file which itself is initially binary data? -- Posted via http://www.ruby-forum.com/.
My server does not support filesystem writing,so i can not store the binary_file data as an image in the file directory,and then send the image using Net::FTP#putbinaryfile method. Could i send the binary_file directly using Net::FTP#putbinaryfile(binary_file, remotefile)? -- Posted via http://www.ruby-forum.com/.

thanks,Fred.
But i get the ftppermerror when using storbinary and StringIO.
########
Net::FTP.open(''showreelfinder.com'') do |ftp|
ftp.passive=true
ftp.login(name,password)
ftp.chdir(''www.showreelfinder.com/web/site/temp/uploads/heywatch
/thumbnails'')
thumbnail_file=StringIO.new(thumbnail)
ftp.storbinary("STOR"+"#{thumb_title}",thumbnail_file,1024)
end
###########
The thumbnail is binary file,so can i use the stringio?
can you tell me the details? I can not find an good example in ruby
document.
Thank you very much!

thumbnail_file=StringIO.new(thumbnail) do i need to change the above like this?Because i think the thumbnail is binary file. thumbnail_file=StringIO.new(thumbnail.to_s) -- Posted via http://www.ruby-forum.com/.
