    helpTips = """以下是 安全加密连接FTPS 和 多用户配置 说明, 普通用户一般不需要。

==== FTPS 配置 ====

本软件默认使用 FTP 明文传输数据，如果数据比较敏感，或者网络环境不安全，则可以按以下步骤开启 FTPS 加密传输数据。

在 "Linux" 或 "MinGW64" 终端使用 "openssl" (命令如下，需填入一些简单信息: 地区/名字/Email等)生成SSL证书文件(ftpServer.key和ftpServer.crt), "不要重命名"文件为其他名称。

openssl req -x509 -newkey rsa:2048 -keyout ftpServer.key -out ftpServer.crt -nodes -days 36500

直接将 ftpServer.key 和 ftpServer.crt 放到程序所在目录, 开启服务时若存在这两个文件, 则启用加密传输 "FTPS [TLS/SSL显式加密, TLSv1.3]"。
Windows文件管理器对 显式FTPS 支持不佳, 推荐使用开源软件 "WinSCP" FTP客户端, 对 FTPS 支持比较好。
开启 "FTPS 加密传输" 后, 会影响传输性能, 最大传输速度会降到 50MiB/s 左右。若对网络安全没那么高要求, 不建议加密。


==== 多用户配置 ====

一般单人使用时，只需在软件主页面设置用户名和密码即可。如果需要开放给多人使用，可以按以下步骤建立多个用户，分配不同的读写权限和根目录。

在主程序所在目录新建文件 "FtpServerUserList.csv" , 使用 "Excel"或文本编辑器(需熟悉csv文件格式)编辑, 一行一个配置: 
第一列: 用户名, 限定英文大小写/数字。
第二列: 密码, 限定英文大小写/数字/符号。
第三列: 权限, 详细配置如下。
第四列: 根目录路径。

详细权限配置: 
使用 "readonly" 或 "只读" 设置为 "只读权限"。
使用 "readwrite" 或 "读写" 设置为 "读写权限"。
使用 "自定义" 权限设置, 从以下权限挑选自行组合(注意大小写)。

参考链接: https://pyftpdlib.readthedocs.io/en/latest/api.html#pyftpdlib.authorizers.DummyAuthorizer.add_user

读取权限: 
 "e" = 更改目录 (CWD 命令)
 "l" = 列出文件 (LIST、NLST、STAT、MLSD、MLST、SIZE、MDTM 命令)
 "r" = 从服务器检索文件 (RETR 命令)

写入权限: 
 "a" = 将数据附加到现有文件 (APPE 命令)
 "d" = 删除文件或目录 (DELE、RMD 命令)
 "f" = 重命名文件或目录 (RNFR、RNTO 命令)
 "m" = 创建目录 (MKD 命令)
 "w" = 将文件存储到服务器 (STOR、STOU 命令)
 "M" = 更改文件模式 (SITE CHMOD 命令)
 "T" = 更新文件上次修改时间 (MFMT 命令)
    

例如:
| JARK006   | 123456 | readonly  | D:\\Downloads |
| JARK007   | 456789 | readwrite | D:\\Data      |
| JARK008   | abc123 | 只读      | D:\\FtpRoot   |
| JARK009   | abc456 | elr       | D:\\FtpRoot   |
| anonymous |        | elr       | D:\\FtpRoot   |
| ...       |        |           |              |
注: anonymous 是匿名用户, 允许不设密码, 其他用户必须设置密码。

其他:
1. 若读取到有效配置, 则自动 "禁用"主页面的用户/密码设置。
2. 密码不要出现英文逗号 "," 字符, 以免和csv文本格式冲突。
3. 若临时不需多用户配置, 可将配置文件 "删除" 或 "重命名" 为其他名称。
4. 配置文件可以是UTF-8或GBK编码。
