加密

• 使用**hashlib.sha256()**

import hashlib
from flask import Blueprint, request, render_template
from apps.user.models import User
from exts import db

user_bp = Blueprint('user', __name__)


# 注册
@user_bp.route('/register', methods=['GET', 'POST'])
def register():
    if request.method == 'POST':
        username = request.form.get('username')
        password = request.form.get('password')
        repassword = request.form.get('repassword')
        phone = request.form.get('phone')
        if repassword == password:
            # 与模型结合
            # 创建模型对象
            user = User()
            # 给对象赋值
            user.username = username
            # 把加密后的密码赋值给user对象
            user.password = hashlib.sha256(password.encode('utf-8')).hexdigest()
            user.phone = phone
            # 添加
            # 将user对象添加到session
            db.session.add(user)
            # 提交
            db.session.commit()
            return '注册成功'
        else:
            return '两次密码不一致'
    else:
        return render_template('user/register.html')

查询

• 语法 :
  • 查询所有数据 : 对象.query.all()

用户首页

views.py

# 用户首页
@user_bp.route('/')
def user_center():
    # 查询数据库中的数据
    user = User.query.all()  # select * from user;
    print(user)
    return render_template('user/center.html', user=user)

center.html
