egg實現登錄鑒權（四）：人員新增和密碼修改

需求

• 新增人員

• 請求header中需加token
• 新增直接傳nickname，nickname不重名
• password默認是123456的md5加密密文

• 修改密碼

• 請求header中需加token
• 傳參：新密碼

實現

代碼基本上沒有改動，只需要改動路由（router.js），控制器（controller）,服務（service）

• 以下幾項都和前一篇（egg實現登錄鑒權（三）：密碼的md5加密及驗證）相同

• 數據庫
• 依賴包
• 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 {
  // 登錄
  async login() {
    const { ctx, app } = this;
    const data = ctx.request.body;
    // 判斷該用戶是否存在並且密碼是否正確
    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: '登錄成功', token };
    } else {
      ctx.body = { code: 400, msg: '登錄失敗' };
    }
  }
  // 獲取所有用戶
  async index() {
    const { ctx } = this;
    const data = await ctx.service.user.getUser();
    ctx.body = { code: 200, msg: '查詢成功', data };
  }
  // 通過id獲取用戶
  async show() {
    const { ctx } = this;
    const data = await ctx.service.user.getUser(ctx.params.id);
    ctx.body = { code: 200, msg: '查詢成功', data };
  }
  // 創建人員
  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' };
  }
  // 修改密碼
  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');
// 設置默認密碼
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 {
  // 查詢user表，驗證密碼和花名
  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;
  }
  // 獲取用戶，不傳id則查詢所有
  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);
  }
  // 新增人員
  async addUser(nickname) {
    const { ctx } = this;
    const password = this.getMd5Data(DEFAULT_PWD);
    await ctx.model.User.create({ nickname, password });
  }
  // 修改密碼
  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 });
  }
  // 專門對數據進行md5加密的方法，輸入明文返回密文
  getMd5Data(data) {
    return crypto.createHash('md5').update(data).digest('hex');
  }
}
module.exports = UserService;
