FTP库错误:获得超过8192个字节

Question

上传文件大小超过8192字节时,Python失败.而例外只是"超过8192字节".是否有上传大文件的解决方案.

try:
    ftp = ftplib.FTP(str_ftp_server )
    ftp.login(str_ftp_user, str_ftp_pass)
except Exception as e:
    print('Connecting ftp server failed')
    return False

try:
    print('Uploading file ' + str_param_filename)
    file_for_ftp_upload = open(str_param_filename, 'r')
    ftp.storlines('STOR ' + str_param_filename, file_for_ftp_upload)

    ftp.close()
    file_for_ftp_upload.close()
    print('File upload is successful.')
except Exception as e:
    print('File upload failed !!!exception is here!!!')
    print(e.args)
    return False

return True

Answer 1

storlines一次读取一行文本文件,8192是每行的最大大小.作为上传功能的核心,您可能最好使用它:

with open(str_param_filename, 'rb') as ftpup:
    ftp.storbinary('STOR ' + str_param_filename, ftpup)
    ftp.close()

它以二进制形式读取和存储,一次一个块(默认值为8192),但对于任何大小的文件都应该可以正常工作.
