程序运行:
- 首先运行服务端servers.py;
- 然后运行login_GUI.py启动登录界面。
数据库结构:
由于当前功能还不完整，只有一个用户表和消息表
用户表(database_usersprofile)：
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`password` varchar(65) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,

`last_login` datetime(6) NULL DEFAULT NULL,
`last_ip` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
PRIMARY KEY (`id`) USING BTREE
消息表(messages):

`send_to` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
