egg实现登录鉴权（四）：人员新增和密码修改

需求

• 新增人员

• 请求header中需加token
• 新增直接传nickname，nickname不重名
• password默认是123456的md5加密密文

• 修改密码

• 请求header中需加token
• 传参：新密码

实现

代码基本上没有改动，只需要改动路由（router.js），控制器（controller）,服务（service）

• 以下几项都和前一篇（egg实现登录鉴权（三）：密码的md5加密及验证）相同

• 数据库
• 依赖包
• config/config.default.js
• config/plugin.js
• app/model/user.js

• app/controller/user.js

'use strict';

const Controller = require('egg').Controller;

class UserController extends Controller {
  // 登录
  async login() {
    const { ctx, app } = this;
    const data = ctx.request.body;
    // 判断该用户是否存在并且密码是否正确
    const isValidUser = await ctx.service.user.validUser(data.nickname, data.password);
    if (isValidUser) {
      const token = app.jwt.sign({ nickname: data.nickname }, app.config.jwt.secret);
      ctx.body = { code: 200, msg: '登录成功', token };
    } else {
      ctx.body = { code: 400, msg: '登录失败' };
    }
  }
  // 获取所有用户
  async index() {
    const { ctx } = this;
    const data = await ctx.service.user.getUser();
    ctx.body = { code: 200, msg: '查询成功', data };
  }
  // 通过id获取用户
  async show() {
    const { ctx } = this;
    const data = await ctx.service.user.getUser(ctx.params.id);
    ctx.body = { code: 200, msg: '查询成功', data };
  }
  // 创建人员
  async create() {
    const { ctx } = this;
    const { nickname } = ctx.request.body;
    await ctx.service.user.addUser(nickname);
    ctx.body = { code: 200, msg: '新增成功' };
  }
  // 修改密码
  async updatePwd() {
    const { ctx } = this;
    const { password } = ctx.request.body;
    await ctx.service.user.editPwd(ctx.params.id, password);
    ctx.body = { code: 200, msg: '修改成功' };
  }
}

module.exports = UserController;

• app/service/user.js

'use strict';

const Service = require('egg').Service;
const crypto = require('crypto');
// 设置默认密码
const DEFAULT_PWD = '123456';
function toInt(str) {
  if (typeof str === 'number') return str;
  if (!str) return str;
  return parseInt(str, 10) || 0;
}

class UserService extends Service {
  // 查询user表，验证密码和花名
  async validUser(nickname, password) {
    const data = await this.getUser();
    const pwd = this.getMd5Data(password);
    for (const item of data) {
      if (item.nickname === nickname && item.password === pwd) return true;
    }
    return false;
  }
  // 获取用户，不传id则查询所有
  async getUser(id) {
    const { ctx } = this;
    const query = { limit: toInt(ctx.query.limit), offset: toInt(ctx.query.offset) };
    if (id) {
      return await ctx.model.User.findByPk(toInt(id));
    }
    return await ctx.model.User.findAll(query);
  }
  // 新增人员
  async addUser(nickname) {
    const { ctx } = this;
    const password = this.getMd5Data(DEFAULT_PWD);
    await ctx.model.User.create({ nickname, password });
  }
  // 修改密码
  async editPwd(id, password) {
    const { ctx } = this;
    const user = await ctx.model.User.findByPk(id);
    const newPwd = this.getMd5Data(password);
    await user.update({ password: newPwd });
  }
  // 专门对数据进行md5加密的方法，输入明文返回密文
  getMd5Data(data) {
    return crypto.createHash('md5').update(data).digest('hex');
  }
}
module.exports = UserService;

• app/router.js

'use strict';

/**
 * @param {Egg.Application} app - egg application

module.exports = app => {
  const { router, controller, jwt } = app;
  router.get('/', controller.home.index);

  router.post('/user/login', controller.user.login);
  // 查询
  router.get('/user', controller.user.index);
  router.get('/user/:id', jwt, controller.user.show);
  // 新增
  router.put('/user', jwt, controller.user.create);
  // 修改密码
  router.post('/user/:id', jwt, controller.user.updatePwd);
