def main():

    add_user(username, password, homedir, perm="elr", msg_login="Login successful.", msg_quit="Goodbye.")
    Add a user to the virtual users table. AuthorizerError exception is raised on error conditions such as insufficient permissions or duplicate usernames. Optional perm argument is a set of letters referencing the user’s permissions. Every letter is used to indicate that the access rights the current FTP user has over the following specific actions are granted. The available permissions are the following listed below:

    Read permissions:

    "e" = change directory (CWD, CDUP commands)
    "l" = list files (LIST, NLST, STAT, MLSD, MLST, SIZE commands)
    "r" = retrieve file from the server (RETR command)
    Write permissions:

    "a" = append data to an existing file (APPE command)
    "d" = delete file or directory (DELE, RMD commands)
    "f" = rename file or directory (RNFR, RNTO commands)
    "m" = create directory (MKD command)
    "w" = store a file to the server (STOR, STOU commands)
    "M" = change file mode / permission (SITE CHMOD command) New in 0.7.0
    "T" = change file modification time (SITE MFMT command) New in 1.5.3
    Optional msg_login and msg_quit arguments can be specified to provide customized response strings when user log-in and quit. The perm argument of the add_user() method refers to user’s permissions. Every letter is used to indicate that the access rights the current FTP user has over the following specific actions are granted.


    add_anonymous(homedir, **kwargs)
    Add an anonymous user to the virtual users table. AuthorizerError exception is raised on error conditions such as insufficient permissions, missing home directory, or duplicate anonymous users. The keyword arguments in kwargs are the same expected by add_user() method: perm, msg_login and msg_quit. The optional perm keyword argument is a string defaulting to “elr” referencing “read-only” anonymous user’s permission. Using a “write” value results in a RuntimeWarning.

注意：

Windowsファイルエクスプローラーを使用してFTPにログインし、文字化けした漢字を表示します

Windowsファイルエクスプローラーはgbkエンコーディングを使用し、pyftpdlibはデフォルトでutf8エンコーディングを使用するため、中国語を表示すると文字化けが表示されます
