9 | 10 | ##### 二. 使用说明 11 | 12 | 1. 界面逻辑 13 | 14 | img1 15 | 16 | 17 | 18 | 19 | 2. 该GUI界面的主要用于应用程序的登录和注册，并用数据库`sqlite3`保存用户的信息，但只是保存在本地 20 | 21 | 3. 该GUI界面使用十分简单，与平常的网页版注册登录没有太多区别，另外有管理员的管理界面，可用于对所有用户的相关操作 22 | 23 | 4. 本GUI界面应该在**Python3**环境下运行，python2似乎`不支持`PyQt，本人在`PyCharm 2019.2.5 + Anaconda3 `环境下可以成功运行 24 | 25 | 5. 下面为部分功能演示gif，图片并不是很清晰，可自行运行测试效果 26 | 27 | 演示gif 28 | 29 | 30 | 31 | 32 | 33 |
34 | 35 | ##### 三. 模块说明 36 | 37 | img2 38 | 39 | 40 | 1. Login.py 41 | 42 | 该模块主要负责用户的登录，以及与其他窗口的联系，使用时应该注意安装`PyQt5`模块，如果没有安装则会调用`os`模块使用`pip`进行安装，若安装失败，则无法进行下一步，但是还是建议自己先配置好pyqt5的环境 43 | 44 | 45 | 46 | 2. Sign_Up.py 47 | 48 | 该模块主要负责用户的注册，注册时候必须两次输入的密码相同并且用户名不存在方可成功注册，否则提示用户名已经存在，并要求重新填写，注册完成之后，窗口关闭，返回之前的登录窗口 49 | 50 | 51 | 52 | 3. Admin.py 53 | 54 | 该模块负责管理员对所有用户的操作，包括删除，修改密码，添加用户等, 55 | 56 | 删除用户的时候，需要选择前面的选择框，然后点击`Delete`， `Select All`可方便一次性选择全部，点击之后变为`Unselect`,可用于不选择任何用户，`Clear`可一次性删除全部，包括`admin`，但是之后仍会自动生成`admin`并设置好默认密码，`Refresh`可以更新表格，将数据库中的数据重新添加到表格中，`Update`必须对应已有的用户名，否则报错提示，`Add`可以实现添加用户，但必须是数据库中没有的用户，`Show`可以用于添加用户时的密码框文本是否显式显示出来，点击之后变为`Hide` 57 | 58 | 59 | 60 | 4. Database.py 61 | 62 | 为操作数据库提供接口，可实现插入数据，获取数据，以用户名查找密码，以用户名更新密码，以用户名删除数据，清空数据库等功能 63 | 64 | 65 | 66 | 5. Main.py 67 | 68 | 该模块为用户登录后所看到的界面，可由自己自定义设置，在这里并没有过多的设置，只是展现一个图像，表示登录完成 69 | 70 | 71 | ##### 四、不足之处 72 | - 由于时间问题，主界面并没有进行相关的设置，显得比较简陋 73 | - 部分代码显得有点冗余，可以进行更细致的模块化，减少代码量 74 | - 囿于能力问题，总体界面非动态，并且设置了不可改变的大小 75 | - ...... 76 | 77 | 78 | 79 | -------------------------------------------------------------------------------- /PyQt登录界面/Sign_Up.py: -------------------------------------------------------------------------------- 1 | #
