Datei von SD-Karte auf FileZilla Server hochladen

Question

Meine Anwendung lädt die Datei von der SD-Karte in das Verzeichnis auf dem FTP-Server von FileZilla. Nach dem Ausführen meiner Anwendung gibt es eine Ausnahme, die ich nach so vielen Suchen nicht lösen kann.

hier ist die Protokoll Katze Ausgabe:

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

     async.execute(); 

     }

     ftp.bin();

     // Upload some files. 
     ftp.stor(new File(Environment.getExternalStorageDirectory().getParent() + "/invite_json.txt"));

     return null; 
     }

     } 

Answer 1

Es scheint, dass die Umsetzung SimpleFtp Bibliothek nicht auf die FTP-Spezifikation konform ist (RFC 959). Nach der Quelle gefunden here erwartet es die erste Antwort des FTP-Servers mit "220 " zu starten, während der RFC angibt, dass [eine] FTP-Antwort besteht aus einer dreistelligen Zahl (als drei alphanumerische Zeichen übertragen) gefolgt von etwas Text. Also eine Antwort beginnend mit "220-" ist erlaubt.

Ich empfehle eine bessere FTP-Bibliothek wie apache commons ftp oder ftp4j.

Nach so vielen Tagen habe ich wieder an diesem Ding gearbeitet und erfolgreich die Dinge in Gang gebracht. Also, ich schreibe meine Antwort. Hoffe, es würde jemandem helfen.

Das ist mein Hauptaktivität Code:

} 

Bitte überprüfen Sie die Protokoll Katze, während die Anwendung ausgeführt wird Sie kennen lernen, wie das funktioniert. Danke.
