前言
本期给大家带来，Flask+MySql+前端的注册登录模块实现
1. 登录模块
# 登录页面
@app.route('/login',methods=['GET','POST'])
def login():
if request.method == 'GET':
return render_template('login.html')
elif request.method == 'POST':
# 将输入的用户登录信息保存为字典
request.form = dict(request.form)
# 进行过滤,如果邮箱和密码都在数据库中，返回True
def filter_fn(item):
return request.form['email'] in item and request.form['password'] in item
users = query.querys('select * from user',[],'select')
filter_user = list(filter(filter_fn,users))
# 验证成功，进入index.html
if len(filter_user):
session['email'] = request.form['email']
return redirect('/home')
else:
return render_template('error.html', message='用户邮箱或密码输入错误')
@app.route('/loginOut',methods=['GET','POST'])
def loginOut():
session.clear() # 清除session中存储的登录数据
return redirect('/login')
2. 注册模块
# 注册页面
@app.route('/register',methods=['GET','POST'])
def register():
if request.method == 'GET':
return render_template('register.html')
elif request.method == 'POST':
request.form = dict(request.form)
# 判断第一次输入密码和第二次是否相同
if request.form['password'] != request.form['passwordChecked']:
return render_template('error.html',message='两次输入密码不符，请重新输入')
def filter_fn(item):
return request.form['email'] in item
users = query.querys('select * from user',[],'select')
filter_list = list(filter(filter_fn, users))
if len(filter_list):
return render_template('error.html',message='该用户已被注册')
else:
# 将新注册的数据存储到数据库
query.querys('insert into user(email,password) values(%s,%s)',[request.form['email'],request.form['password']])
return redirect('/login')
