android - samsung - Subiendo archivo desde la tarjeta SD al servidor FileZilla

fusionar memoria interna con sd android 7

Question

Mi aplicación está cargando el archivo de la tarjeta SD al directorio en el servidor FTP de FileZilla. Después de ejecutar mi aplicación, me da una excepción que no puedo resolver después de tantas búsquedas.

aquí está la salida del log de gato:

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

Parece que la implementación de la biblioteca SimpleFTP no se ajusta a la especificación FTP ( RFC 959 ). Según la fuente que se encuentra aquí , espera que la respuesta inicial del servidor FTP comience con "220 " mientras que RFC especifica que [una] respuesta FTP consiste en un número de tres dígitos (transmitido como tres caracteres alfanuméricos) seguido de un texto. Por lo tanto, se permite una respuesta que comience con "220-" .

Sugiero usar una mejor biblioteca FTP, como apache commons ftp o ftp4j .

Después de tantos días trabajé en esto nuevamente y logré que las cosas funcionen. Por lo tanto, estoy publicando mi respuesta. Espero que ayude a alguien.

Verifique el log cat mientras se ejecuta su aplicación, sabrá cómo funciona esto. Gracias.
