+### 3.1.2. 注册页面
+
+
+
+该页面将对输入进行如下检查：
+
+- **检查身份证格式**
+
+ ```javascript
+ checkInfo.checkCardCode = function() {
+ let cardCode = document.getElementById('cardCode').value
+ let regexCardCode = /^([1-6][1-9]|50)\d{4}(18|19|20)\d{2}((0[1-9])|10|11|12)(([0-2][1-9])|10|20|30|31)\d{3}[0-9Xx]$/
+ if(!regexCardCode.test(cardCode)) {
+ alert('身份证号格式有误')
+ return false
+ }
+ return true
+ }
+ ```
+
+ 如果格式不正确，将弹出警告：
+
+ 
+
+- **检查手机号格式**
+
+ ```javascript
+ checkInfo.checkMobileNo = function() {
+ let mobileNo = document.getElementById('mobileNo').value
+ let regexMobileNo = /^1[3-9]\d{9}$/
+ if (!regexMobileNo.test(mobileNo)) {
+ alert('手机号格式有误')
+ return false
+ }
+ return true
+ }
+ ```
+
+ 如果格式不正确，将弹出警告：
+
+ 
+
+- **检查密码格式**
+
+ 如果格式不正确，将弹出警告：
+
+ 
+
+- **检查确认密码是否与第一次输入的密码匹配**
+
+ ```javascript
+ checkInfo.checkPassword = function() {
+ let password = document.getElementById('password')
+ let regexPassword = /^[A-Za-z0-9\W_]{6,20}$/
+ if (!regexPassword.test(password.value)) {
+ alert("密码须为长度为6-20位字母、数字或符号")
+ return false
+ }
+ let confirmPassword = document.getElementById('confirmPassword')
+ if (password.value !== confirmPassword.value) {
+ alert("两次输入的密码不一致")
+ return false
+ }
+ return true
+ }
+ ```
+
+ 如果不匹配，将弹出警告：
+
+ 
+
+页面会对密码使用 `md5码` 加密传输至后端（效果见 `3.2.1.2. 注册页面请求处理函数` 部分的数据库查询结果截图）。
+
+```javascript
+document.getElementById('encryptedPassword').value = md5(
+ document.getElementById('password').value
+)
+```
+
+注册成功后，页面跳转回主页，并弹出注册成功通知：
+
+
+
+### 3.1.3. 修改账户信息页面
+
+修改账户信息页面可以选择三种修改方式，通过点击下拉框即可选择：
+
+- 删除账户：
+
+ 
+
+- 修改密码：
+
+ 
+
+- 修改手机号码：
+
+ 
+
+这里使用了 Javasript 代码操作列表的 `display` 属性，从而控制列表项的显示：
+
+```javascript
+modify.showModifyPassword = function() {
+ let modifyType = document.getElementById('modifyType').value
+ let info = {
+ modifyPasswordLis: document.getElementsByClassName('modifyPassword'),
+ modifymobileNoLis: document.getElementsByClassName('modifymobileNo'),
+ }
+ // 遍历隐藏所有元素
+ for (let key in info) {
+ let elements = info[key];
+ for (let item of elements) {
+ item.style.display = 'none'; // 确保所有相关元素被隐藏
+ }
+ }
+ // 根据 modifyType 显示相关元素
+ if (modifyType === "2") {
+ for (let item of info.modifyPasswordLis) {
+ item.style.display = 'block';
+ }
+ } else if (modifyType === "3") {
+ for (let item of info.modifymobileNoLis) {
+ item.style.display = 'block';
+ }
+ }
+}
+```
+
+上述修改都会在后端检查证件号码和登录密码是否匹配（见后端部分实验结果）。
+
+修改密码将会做密码二次匹配检查、密码格式检查，修改手机号将会做手机号格式化检查。弹出的提示和注册页面提示一样，这里不作赘述。
+
+## 3.2. 后端
+
+### 3.2.1. Flask 框架
+
+Flask 框架负责作为 Web 服务器、应用服务器的实现方式。
+
+我在代码代码中实现了一个函数，用于连接数据库，以便后续获取 cursor 以及关闭连接。
+
+```python
+def get_db():
+ return pymysql.connect(
+ host='localhost', user='kejingfan',
+ password='PASSWORD', database='TESTDB'
+ )
+```
+
+对于每一个前端页面，都需要在 Flask 的调用代码中编写一个函数来处理该页面的 GET / POST 请求。
+
+#### 3.2.1.1. 主页请求处理函数
+
+主页目前只有 GET 请求，因此只需要返回 `index.html` 即可。
+
+```python
+@app.route("/")
+def index():
+ return render_template("index.html")
+```
+
+#### 3.2.1.2. 注册页面请求处理函数
+
+注册页面中，收到 GET 请求，返回 `signup.html` ；
+
+```python
+@app.route("/signup.html", methods=('GET', 'POST'))
+def signup():
+ if request.method == 'GET':
+ return render_template('signup.html')
+```
+
+收到 POST 请求，需要处理返回的表单。表单一共有 4 项：`'cardCode', 'name', 'mobileNo', 'encryptedPassword'` 。
+
+```python
+if request.method == 'POST':
+ id = request.form['cardCode']
+ name = request.form['name']
+ phone_number = request.form['mobileNo']
+ password = request.form['encryptedPassword']
+
+ db = get_db()
+ cursor = db.cursor()
+```
+
+首先使用身份证号 `'cardCode'` 项，对数据库进行查询，检查用户是否正在重复注册。
+
+若重复注册，弹出：
+
+
+
+```python
+sql = """
+SELECT COUNT(*) FROM passengers \
+WHERE ID = %s;
+"""
+try:
+ cursor.execute(sql, (id,))
+ id_exist = cursor.fetchall()[0][0]
+except Exception as e:
+ flash("数据库异常，查询失败")
+ print(e)
+ return redirect(url_for('signup'))
+if (id_exist != 0):
+ flash("您已注册过，请勿重复注册")
+ db.close()
+ return redirect(url_for('index'))
+```
+
+如果没有检索到已注册信息，则插入注册信息：
+
+```python
+sql = '''
+INSERT INTO passengers (ID, `Name`, Phone_number, `Password`) \
+VALUES (%s, %s, %s, %s); \
+'''
+try:
+ cursor.execute(sql, (id, name, phone_number, password))
+ db.commit()
+ flash("注册成功")
+except Exception as e:
+ db.rollback()
+ print(e)
+ flash("数据库异常，注册失败")
+db.close()
+return redirect(url_for('index'))
+```
+
+此时数据库可以查询到：
+
+
+
+#### 3.2.1.3. 修改账户信息页面请求处理函数
+
+修改账户信息页面中，收到 GET 请求，返回 `modify.html` ；
+
+```python
+@app.route("/modify.html", methods=('GET', 'POST'))
+def modify():
+ if request.method == 'GET':
+ return render_template('modify.html')
+```
+
+收到 POST 请求，需要处理返回的表单。表单一共有 5 项：
+
+`'cardCode', 'encryptedPassword', 'modifyType', ''encryptedNewPassword'', 'mobileNo'` 。
+
+首先需要验证用户是否存在，且密码正确。这里需要做两个查询操作，分别查询 `ID` 的数量以及 `Password` 的值。
+
+将验证过程封装成函数：
+
+```python
+def verify_user(cursor:Cursor, id:str, password:str) -> str:
+ # 检查已有用户
+ sql = """
+ SELECT COUNT(*) FROM passengers \
+ WHERE ID = %s;
+ """
+ try:
+ cursor.execute(sql, (id,))
+ id_exist = cursor.fetchall()[0][0]
+ except Exception as e:
+ flash("数据库异常，查询失败")
+ print(e)
+ return redirect(url_for('signup'))
+ if (id_exist == 0):
+ return "NO_USER"
+
+ # 检查密码
+ sql = """
+ SELECT `Password` FROM passengers \
+ WHERE ID = %s;
+ """
+ try:
+ cursor.execute(sql, (id,))
+ record_password = cursor.fetchall()[0][0]
+ except Exception as e:
+ flash("数据库异常，查询失败")
+ print(e)
+ return redirect(url_for('modify'))
+ if (record_password != password):
+ return "WRONG_PASSWORD"
+
+ return "USER_VERIFIED"
+```
+
+判断验证结果，作出响应：
+
+```python
+id = request.form['cardCode']
+password = request.form['encryptedPassword']
+db = get_db()
+cursor = db.cursor()
+
+verify_info = verify_user(cursor, id, password)
+if (verify_info == "NO_USER"):
+ flash("您未注册过，无法修改账号")
+ db.close()
+ return redirect(url_for('signup'))
+elif (verify_info == "WRONG_PASSWORD"):
+ flash("密码错误")
+ db.close()
+ return redirect(url_for('modify'))
+```
+
+如果用户没有注册：
+
+
+
+如果密码错误：
+
+
+
+验证通过后，需要根据请求对数据库进行更改。
+
+编写了一个类专门用来处理修改内容、数据库修改指令和提示信息：
+
+```python
+class ModifyInfo:
+ def __init__(self, form:Dict[str, str]):
+ self.id = form['cardCode']
+ modifyType = form['modifyType']
+ self.new_password = form['encryptedNewPassword']
+ self.phone_number = form['mobileNo']
+ modifyType2command = {
+ '1':'delete account',
+ '2':'modify Password',
+ '3':'modify Phone_Number'
+ }
+ self.sql_dict = {
+ 'delete account': 'DELETE FROM passengers WHERE ID = %s;',
+ 'modify Password': 'UPDATE passengers SET `Password` = %s WHERE ID = %s;',
+ 'modify Phone_Number': 'UPDATE passengers SET Phone_number = %s WHERE ID = %s;'
+ }
+ self.sql_args_dict = {
+ 'delete account': (self.id,),
+ 'modify Password': (self.new_password, self.id),
+ 'modify Phone_Number': (self.phone_number, self.id)
+ }
+ self.ok_message_dict = {
+ 'delete account': "删除账户成功",
+ 'modify Password': "修改密码成功",
+ 'modify Phone_Number': "修改手机号成功"
+ }
+ self.fail_message_dict = {
+ 'delete account': "数据库异常，删除账户失败",
+ 'modify Password': "数据库异常，修改密码失败",
+ 'modify Phone_Number': "数据库异常，修改手机号失败"
+ }
+ self.command = modifyType2command[modifyType]
+ def get_sql(self):
+ return self.sql_dict[self.command]
+ def get_args(self):
+ return self.sql_args_dict[self.command]
+ def get_ok_message(self):
+ return self.ok_message_dict[self.command]
+ def get_fail_message(self):
+ return self.fail_message_dict[self.command]
+```
+
+在处理函数中创建该类对象，并调用该对象方法获取操作参数：
+
+```python
+modifyInfo = ModifyInfo(request.form)
+try:
+ cursor.execute(modifyInfo.get_sql(), modifyInfo.get_args())
+ db.commit()
+ flash(modifyInfo.get_ok_message())
+except Exception as e:
+ db.rollback()
+ print(e)
+ flash(modifyInfo.get_fail_message())
+db.close()
+return redirect(url_for('index'))
+```
+
+修改密码成功后：
+
+
+
+
+
+修改手机号成功后：
+
+
+
+
+
+删除账号成功后：
+
+
+
+
+
+### 3.2.2. 数据库服务器
+
+本实验使用 MySQL 作为数据库。
+
+编写了一个 SQL 脚本和一个 Python 文件用于初始化测试数据库：
+
+```mysql
+DROP TABLE IF EXISTS passengers;
+
+CREATE TABLE passengers (
+ ID BIGINT PRIMARY KEY,
+ `Name` VARCHAR (255) NOT NULL,
+ Phone_number BIGINT UNIQUE NOT NULL,
+ `Password` VARCHAR (255) NOT NULL,
+ CHECK (ID REGEXP '^\\d{18}$'),
+ CHECK (Phone_number REGEXP '^\\d{11}$')
+);
+```
+
+```python
+import pymysql
+
+db = pymysql.connect(
+ host='localhost', user='kejingfan',
+ password='PASSWORD', database='TESTDB'
+)
+
+cursor = db.cursor()
+
+with open('db.sql', 'r') as f:
+ sql_commands = f.read().split(';')
+ for command in sql_commands:
+ if command.strip(): # 确保不执行空命令
+ cursor.execute(command)
+
+db.close()
+```
