Caricamento file da scheda SD a FileZilla Server

Question

La mia applicazione sta caricando il file dalla scheda SD nella directory su FileZilla FTP Server. Dopo aver eseguito la mia app, mi dà un'eccezione che non riesco a risolvere dopo tante ricerche.

Ecco l'output del log gatto:

06-24 11:06:53.715: W/System.err(1304): java.io.IOException: SimpleFTP received an unknown response when connecting to the FTP server: 220-FileZilla Server version 0.9.41 beta

Answer 1

Sembra che l'attuazione libreria SimpleFtp non è conforme alla specifica FTP (RFC 959). Secondo la fonte trovata here, si aspetta che la risposta iniziale del server FTP inizi con "220 " mentre la RFC specifica che la risposta FTP [an] è composta da un numero di tre cifre (trasmesso come tre caratteri alfanumerici) seguito da un testo. Quindi è consentita una risposta a partire da "220-".

Suggerisco di utilizzare una libreria FTP migliore come apache commons ftp o ftp4j.

} 

Si prega di verificare il gatto registro mentre l'applicazione è in esecuzione si arriva a sapere come questo funziona. Grazie.
