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);
};
