前言与准备

本次实验是大二数据库期末大作业，我采用的是python语言和mysql8.0.27制作的基于cs构架的数据库框架，由于之前从未了解过python语言，所以代码部分语言较为粗暴，未成年人请在父母陪同下观看（狗头），至于mysql的安装与基本使用，在网络上的教程较多，可自行查找。
本次代码编写，我分成了3个部分，即分别编写登录界面、用户界面和管理员界面的代码，最后在利用一个统一的变量参数来串联起来，而由于代码能力的限制，不是我懒，最后仅仅实现了本地使用，至于联机的应用，交给各位自行探索，顺便学会后给我发份代码。

登录界面

登录界面的设计较为简单，或者说整个实验的代码都是同一个道理的堆砌，并没有太多不同。
首先是学会python与mysql的连接，我使用的是pymysql这个模块，之后便在界面对应按钮上提供函数即可，如登录按钮，则在读取数据库后穷举其中的账号密码与输入的账号密码做比较即可，如下：

def auto_login():# 连接数据库db = pymysql.connect(host='localhost', user='root', password='159357', db='sdusql', port=3306)# 获取操作游标cur = db.cursor()# 查询数据库sql = 'select * from user'entry1 = input1.get()entry2 = input2.get()flag = Falsecur.execute(sql)  # 执行查询results = cur.fetchall()  # 获取所有查询数据global usernamefor row in results:uid = row[3]  # 账号pwd = row[4]  # 密码# 判断输入的账号和密码是否正确if entry1 == uid and entry2 == pwd:print('登录成功')username = row[0]success(username)flag = Truebreakif flag == False:sql = 'select * from admin'cur.execute(sql)  # 执行查询results = cur.fetchall()  # 获取所有查询数据for row in results:uid = row[0]  # 账号pwd = row[1]  # 密码# 判断输入的账号和密码是否正确if entry1 == uid and entry2 == pwd:print('登录成功')username = row[0]success(username)flag = Truebreakif flag == False:fail()cur.close()db.commit()db.close()

代码中之所以穷举了两次，是因为我的代码分别考虑了用户和管理员两套不同的账号，但其实原理一样。不要忙着复制上方代码，因为下面有全套的。

上方为登录界面的代码，每个函数的作用分别在按钮处名字体现，其中需要注意的是在输入日期时要考虑到mysql的日期格式问题，因此在注册处的日期，包括之后的借书日期等都有格式转化的过程。
如果你认真分析了上面的代码，并认为做到这个地步已经够了或不够的兄弟们，可以关闭该文章了。因为剩下两部分的代码本质上只是在重复这个过程，只是将图片、按钮进行更改，你可以自己设计了，而不满足与此的兄弟，我也帮不了你，你可以不要浪费时间了。
以下内容均为水字数

用户界面

用户界面整体上我分为3个部分，分别是公告、书库、用户，这3部分的实现是利用ttk.Notebook实现的，具体的用法可以自行查阅。

公告

本部分是利用了mysql存储长文本的能力实现的，利用tkinter的text在管理员处存入文本，再在数据库中读出利用text显示在用户处（增加不可修改的状态），下方为图片，代码再用户界面最后。

书库

书库中用到最重要的一个功能是tkinter中的tree，它可以在界面中增加一个表格，具体功能请自行查阅。书库所实现的两大部分之一查书，就是利用不同条件查询的书籍显示在表格中。其中在搜书过程中，实现了一次搜书与多次搜书，所谓多次搜书，是利用上一次搜书的结果进行再次搜索。一次与多次搜索均为模糊搜索，即支持关键字乃至间隔字（如输入“三义”出现三国演义）。一次搜索是利用了数据库查询的like与%，而多次搜索则是将当前表格中的书籍与搜索内容比较，python中的fuzzywuzzy模块实现。
另外一大部分是借书，我利用鼠标绑定，在鼠标按键中获取书名，并根据其是否已被借阅、是否丢失判断是否可借，可借则在借阅数据库中增加数据，如获取电脑时间确定结束时间，增加30天作为应还书时间。

用户

用户界面在左侧边栏设置按钮指向不同的界面，其本质是右侧的标签是否显示，利用pack进行控制，在点击某一按钮时，就将其对应标签设置为可见，其他隐藏即可。特附代码：

def changeTag(user, tag=0):frame0.pack_forget()frame2.pack_forget()if tag == 0:frame0.pack(padx=1, pady=1, ipadx=500, ipady=500)elif tag == 2:frame2.pack(padx=1, pady=1, ipadx=500, ipady=500)x = tree2.get_children()for item in x:tree2.delete(item)jie_book(user)

其他的部分只需将自己的想法写出即可。如还书部分可增加异常还书，选择书籍丢失或损坏后赔偿相应的损失，在例如根据其还书时间与设置的应还书时间判断是否违约，违约还可设置对应标志来减少其可借数量（我未实现，懒）。

下方为用户部分全代码（当时懒得写注释，尽力观看）

管理员部分也是同样的3部分，不同的是相应的权限，比如公告部分可以进行输入，书库可以实现书籍的增删改查，其中在这部分，我设置了一个批量添加和导出全部书籍信息。首先利用tkinter.filedialog.askopenfilename模块实现打开文件，在选择对应的excel实现读取数据写入数据库，或者读取数据库写入excel中，特附导出成excel的代码：```python
def in_book():filename = tkinter.filedialog.askopenfilename()if filename != '':in_b.in_excel_b(filename)showinfo('提示', '书籍导入成功')Empty()All()import pymysql
from openpyxl import load_workbookdef in_excel_b(s):# 打开工作薄与工作表wb = load_workbook(s)sheet = wb['Sheet1']# 计算表格数据的有效行数rowsnum = 1while 1:cell = sheet.cell(row=num, column=1).valueif cell:num = num + 1else:breakrows = num - 1db = pymysql.connect(host="localhost",  # 服务器user="root",  # 用户名passwd="159357",  # 密码db="sdusql")  # 数据库名cursor = db.cursor()# 创建插入SQL语句query = "insert ignore into book values (%s, %s, %s, %s, %s,%s,%s)"# for循环迭代读取xls文件中的每行数据, 从第二行开始因为需要跳过标题行# 注意：openpyxl方式表格列标与行标都是从1开始计算的for r in range(2, rows + 1):bname = sheet.cell(row=r, column=1).valueisbn = sheet.cell(row=r, column=2).valueauthor = sheet.cell(row=r, column=3).valuepublisher = sheet.cell(row=r, column=4).valuesort = sheet.cell(row=r, column=5).valuedata = (bname, isbn, author, publisher, sort, '未借阅',None)cursor.execute(query, data)cursor.close()db.commit()db.close()

此外，在管理员界面，管理员也可以为借阅信息进行无限期续期，导出借阅信息和用户信息，终极管理员，也就是我，还可以实现管理员的增加和删除（我有个大胆的想法，管理员可以设置分级，各级管理员可以对应设置低一级管理员的账号，若真按此操作，删除管理员时，请注意其下属管理员的管理）
下为全部代码，同样谨慎观看：

我是利用用户或者管理员的名字作为串联条件，但其实考虑到重名情况，其实账号更为合理。

import start as s
import menu_user as mu
import menu_admin as mas.frame()
if s.username != '':if s.username == 'xwss' or s.username[0:5] == 'admin':ma.mymain(s.username)else:mu.mymain(s.username)

备注

1.列表处我未设置滑轮，请各位注意；
2.代码中存在大量global，是因为之前从未使用过python，思考不周出现的，后来想到的是函数套函数解决，其他更高明的方法敬请指出。
3.代码的三部分分在三个py文件中，又引用在总结的py文件中。
