【Flask】测试平台开发,登陆重构

发布于:2025-08-30 ⋅ 阅读:(18) ⋅ 点赞:(0)

 概述

我们在开篇的时候实现了简单的登陆功能,也实现了一个前后端联调的登陆功能,但是你有没有发现,那个登陆只是一个简单的登陆,且密码在接口返回的过程中是铭文密码,在生产环境中使用肯定是不行的,一般密码都是需要加密的,要么是MD5加密,或者哈希加密,接下来我们重构登陆接口,一同连登陆页面的风格也进行重构,使得风格更加现代化

首先设计数据库关联

  1. 用户表(sys_user

CREATE TABLE `sys_user` (
  `id` bigint NOT NULL AUTO_INCREMENT COMMENT '用户ID',
  `username` varchar(50) NOT NULL COMMENT '用户名',
  `password` varchar(100) NOT NULL COMMENT '密码哈希',
  `name` varchar(50) NOT NULL COMMENT '姓名',
  `email` varchar(100) DEFAULT NULL COMMENT '邮箱',
  `phone` varchar(20) DEFAULT NULL COMMENT '手机号',
  `status` tinyint NOT NULL DEFAULT '1' COMMENT '状态(0-禁用,1-正常)',
  `create_by` bigint NOT NULL COMMENT '创建人ID',
  `created_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `updated_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  PRIMARY KEY (`id`),
  UNIQUE KEY `uk_username` (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='系统用户';

-- 默认超级管理员 (密码: admin123)
INSERT INTO `sys_user` (`id`, `username`, `password`, `name`, `email`, `status`, `create_by`) 
VALUES (1, 'admin', '$2a$10$7JB720yubVSZvUI0rEqK/.VqGOZTH.ulu33dHOiBE8ByOhJIrdAu2', '超级管理员', 'admin@example.com', 1, 1);
  1. 角色表(sys_role

CREATE TABLE `sys_role` (
  `id` bigint NOT NULL AUTO_INCREMENT COMMENT '角色ID',
  `role_name` varchar(50) NOT NULL COMMENT '角色名称',
  `role_code` varchar(50) NOT NULL COMMENT '角色编码',
  `description` varchar(255) DEFAULT NULL COMMENT '角色描述',
  `created_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `updated_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  PRIMARY KEY (`id`),
  UNIQUE KEY `uk_role_code` (`role_code`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='角色表';

-- 默认角色
INSERT INTO `sys_role` (`id`, `role_name`, `role_code`, `description`) 
VALUES (1, '超级管理员', 'SUPER_ADMIN', '拥有系统所有权限'),
       (2, '普通用户', 'NORMAL_USER', '拥有基础操作权限');
  1. 用户角色关联表(sys_user_role

CREATE TABLE `sys_user_role` (
  `id` bigint NOT NULL AUTO_INCREMENT COMMENT 'ID',
  `user_id` bigint NOT NULL COMMENT '用户ID',
  `role_id` bigint NOT NULL COMMENT '角色ID',
  `created_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  PRIMARY KEY (`id`),
  UNIQUE KEY `uk_user_role` (`user_id`,`role_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用户角色关联表';

-- 超级管理员关联超级管理员角色
INSERT INTO `sys_user_role` (`user_id`, `role_id`) VALUES (1, 1);
  1. 菜单表(sys_menu

CREATE TABLE `sys_menu` (
  `id` bigint NOT NULL AUTO_INCREMENT COMMENT '菜单ID',
  `parent_id` bigint NOT NULL DEFAULT '0' COMMENT '父菜单ID',
  `menu_name` varchar(50) NOT NULL COMMENT '菜单名称',
  `path` varchar(255) DEFAULT NULL COMMENT '路由路径',
  `component` varchar(255) DEFAULT NULL COMMENT '前端组件',
  `icon` varchar(50) DEFAULT NULL COMMENT '图标',
  `sort` int NOT NULL DEFAULT '0' COMMENT '排序',
  `menu_type` tinyint NOT NULL COMMENT '菜单类型(1-目录,2-菜单,3-按钮)',
  `permission` varchar(100) DEFAULT NULL COMMENT '权限标识',
  `is_show` tinyint NOT NULL DEFAULT '1' COMMENT '是否显示(0-隐藏,1-显示)',
  `created_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `updated_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='菜单表';

-- 默认菜单示例
INSERT INTO `sys_menu` (`menu_name`, `parent_id`, `path`, `component`, `icon`, `sort`, `menu_type`, `permission`) 
VALUES 
('系统管理', 0, '/system', 'Layout', 'el-icon-setting', 1, 1, NULL),
('用户管理', 1, 'user', 'system/user/index', NULL, 1, 2, 'system:user:list'),
('角色管理', 1, 'role', 'system/role/index', NULL, 2, 2, 'system:role:list'),
('菜单管理', 1, 'menu', 'system/menu/index', NULL, 3, 2, 'system:menu:list'),
('用户查询', 2, NULL, NULL, NULL, 1, 3, 'system:user:query'),
('用户新增', 2, NULL, NULL, NULL, 2, 3, 'system:user:add'),
('用户编辑', 2, NULL, NULL, NULL, 3, 3, 'system:user:edit'),
('用户删除', 2, NULL, NULL, NULL, 4, 3, 'system:user:delete');
  1. 角色权限关联表(sys_role_menu

CREATE TABLE `sys_role_menu` (
  `id` bigint NOT NULL AUTO_INCREMENT COMMENT 'ID',
  `role_id` bigint NOT NULL COMMENT '角色ID',
  `menu_id` bigint NOT NULL COMMENT '菜单ID',
  `created_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  PRIMARY KEY (`id`),
  UNIQUE KEY `uk_role_menu` (`role_id`,`menu_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='角色菜单关联表';

-- 超级管理员拥有所有权限
INSERT INTO `sys_role_menu` (`role_id`, `menu_id`) SELECT 1, id FROM sys_menu;

我们的密码现在是使用的bcrypt加密,所以需要在utils工具中编写JTW,用户解密与数据库中的密码进行比对,符合账号正确密码正确才能登陆系统

重构登陆接口

# -*- coding:utf-8 -*-
import json

from flask import Blueprint
from flask import Blueprint, request, jsonify, g
from models import db
from models.role import Role
from models.user import User
# from utils.jwt import generate_token,login_required
from extensions import db  # 导入 db 实例
from utils.jwt import login_required

app_user = Blueprint("app_user", __name__)

# 原有登录接口改造
from sqlalchemy import select
import bcrypt  # 导入 bcrypt 库

@app_user.route("/api/user/login", methods=['POST'])
def login():
    data = request.get_json()
    username = data.get('username')
    password = data.get('password', '').encode('utf-8')  # 前端密码转为 bytes

    # 1. 反射 sys_user 表并查询用户
    sys_user = db.metadata.tables['sys_user']
    query = select(sys_user).where(sys_user.c.username == username)
    user = db.session.execute(query).fetchone()

    # 2. 基础验证(用户存在 + 状态正常)
    if not user:
        return jsonify(code=40000, message="用户不存在"), 401  # 用户不存在
    if user.status != 1:  # 假设 1=正常,0=禁用
        return jsonify(code=40000, message="用户禁用"), 403  # 用户禁用

    # 3. bcrypt 密码验证(核心修复)
    db_password = user.password.encode('utf-8')  # 数据库密文转为 bytes
    if not bcrypt.checkpw(password, db_password):  # 验证明文密码与密文是否匹配
        return jsonify(code=40000, message="密码错误"), 401  # 密码错误

    # 4. 登录成功(生成 Token 等后续逻辑)
    return jsonify(code=20000, message="success", data={"token": "your_token"})


# 新增用户信息接口
# apis/user.py(假设 info 接口代码)
@app_user.route("/api/user/info", methods=['GET'])
def get_user_info():
    token = request.args.get('token')

    # 1. 验证 token(省略,假设已验证通过)
    # 2. 查询用户信息(使用之前反射表的方式)
    sys_user = db.metadata.tables['sys_user']
    user = db.session.execute(select(sys_user).where(sys_user.c.username == 'admin')).fetchone()

    # 3. 构造符合前端预期的响应格式
    return jsonify({
        "code": 20000,  # 成功状态码(必须为前端约定的值)
        "message": "success",  # 成功消息
        "data": {
            "name": user.name,  # 用户名(从数据库获取)
            "roles": ["admin"],  # 用户角色(根据实际权限获取)
            "avatar": "https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif"  # 头像(可选)
        }
    })


# 新增用户管理接口(管理员创建子账号)
@app_user.route("/api/system/user", methods=['POST'])
@login_required
def create_user():
    current_user = g.user
    # 1. 校验管理员权限
    if not any(role.role_code == 'SUPER_ADMIN' for role in current_user.roles):
        return jsonify(code=403, message='无权限创建用户'), 403

    # 2. 处理请求数据
    data = request.get_json()
    new_user = User(
        username=data['username'],
        name=data['name'],
        create_by=current_user.id
    )
    new_user.set_password(data['password'])  # 密码加密

    # 3. 关联角色
    role_ids = data.get('role_ids', [])
    roles = Role.query.filter(Role.id.in_(role_ids)).all()
    new_user.roles = roles

    db.session.add(new_user)
    db.session.commit()
    return jsonify(code=20000, message='用户创建成功')







配置文件中需要做如下配置,在config中增加配置

# 权限相关配置
JWT_SECRET_KEY = 'your-jwt-secret-key'  # 已有的 JWT 密钥
JWT_ACCESS_TOKEN_EXPIRES = 3600  # Token 有效期 1 小时(已有的配置)

# 添加:权限白名单路径(无需认证即可访问的接口)
PERMISSION_WHITELIST = [
    '/api/user/login',  # 登录接口(必须添加,否则无法登录)
    '/api/user/register',  # 注册接口(如果有)
    '/api/common/captcha',  # 验证码接口(如果有)
    # 前端静态资源路径(如果需要,如 /login.html, /favicon.ico)
    '/', '/login.html', '/favicon.ico'
]

重启服务后重新登陆系统此时可以成功登录

重构登陆页面,之前的登陆页面效果如下,看着不是很直观,我们现在重构下风格--重构前

重构后源码如下:
