python - FTP 库错误 : got more than 8192 bytes

Question

Python 在上传大小超过 8192 字节的文件时失败。而异常(exception)只是“得到超过 8192 个字节”。是否有上传更大文件的解决方案。

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 一次读取一个文本文件一行，8192 是每行的最大大小。您最好使用 , 作为上传功能的核心:

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

这以二进制形式读取和存储，一次一个 block (与 8192 相同的默认值)，但应该适用于任何大小的文件。
