谷粒学院（十五）JWT | 阿里云短信服务 | 登录与注册前后端实现（二）-阿里云开发者社区

7、编写controller，根据手机号发送短信

@RestController
@RequestMapping("/smsservice/sms")
@CrossOrigin
public class SmsApiController {
    @Autowired
    private RedisTemplate<String,String> redisTemplate;
    @Autowired
    private SmsService smsService;
    //阿里云发送短信
    @GetMapping("sendMsgByAly/{phone}")
    public R sendMsgByAly(@PathVariable String phone){
        //生成随机值,传递到阿里云进行发送
        String code = RandomUtil.getSixBitRandom();
        Map <String, Object> param = new HashMap <>();
        param.put("code", code);
        //调用service进行短信发送
        boolean isSend = smsService.sendMsgAly(param, phone);
        if(isSend){
            return R.ok();
        }else{
            return R.error().message("短信发送失败");
        }
    }
    //使用国阳云发送短信
    @GetMapping("sendMsgByGyy/{phone}")
    public R sendMsgByGyy(@PathVariable String phone){
        //从redis中获取验证码,如果获取则直接返回..==> 根据现实情况,用户可以多次发送.
        // String code = redisTemplate.opsForValue().get(phone);
        // if(!StringUtils.isEmpty(code)){
        //     return R.ok();
        // }
        //2.如果redis获取不到,进行阿里云发送
        //生成随机值,传递到阿里云进行发送
        String code = RandomUtil.getSixBitRandom();
        //调用service进行短信发送
        boolean isSend = smsService.sendMsgGyy(code, phone);
        if(isSend){
            //发送成功,把发送成功验证码放入到redis中
            //设置有效时间
            redisTemplate.opsForValue().set(phone, code, 30, TimeUnit.MINUTES);
            return R.ok();
        }else{
            return R.error().message("短信发送失败");
        }
    }
}

8、编写service

@Service
public class SmsServiceImpl implements SmsService {
    //通过阿里云发送短信(由于未申请下来,所以就先写个方法.项目中用国阳云/邮箱进行代替)
    @Override
    public boolean sendMsgAly(Map <String, Object> param, String phone) {
        if(StringUtils.isEmpty(phone)) return false;
        DefaultProfile profile =
                DefaultProfile.getProfile("default", "LTAIq6nIPY09VROj", "FQ7UcixT9wEqMv9F35nORPqKr8XkTF");
        IAcsClient client = new DefaultAcsClient(profile);
        CommonRequest request = new CommonRequest();
        //request.setProtocol(ProtocolType.HTTPS);
        request.setMethod(MethodType.POST);
        request.setDomain("dysmsapi.aliyuncs.com");
        request.setVersion("2017-05-25");
        request.setAction("SendSms");
        request.putQueryParameter("PhoneNumbers", phone);
        request.putQueryParameter("SignName", "我的谷粒在线教育网站");
        request.putQueryParameter("TemplateCode", "templateCode");
        request.putQueryParameter("TemplateParam", JSONObject.toJSONString(param));
        try {
            CommonResponse response = client.getCommonResponse(request);
            System.out.println(response.getData());
            return response.getHttpResponse().isSuccess();
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }
    //使用国阳云发送短信
    @Override
    public boolean sendMsgGyy(String code, String phone) {
        try {
            //真正的短信发送 用于上线
            // SmsUtil.sendMessage(ConstantPropertiesUtil.APP_CODE,phone,code,"30",ConstantPropertiesUtil.SMS_SIGNID,ConstantPropertiesUtil.TEMPLATE_ID);
            //太贵了,先用邮箱代替....
            MailUtils.sendMail("2422737092@qq.com", "[谷粒学院] 验证码: \n"+code+"您正在进行注册,若非本人操作,请勿泄露.30分钟内有效.", "谷粒学院验证码");
            return true;
        }catch (Exception e){
            e.printStackTrace();
            return false;
        }
    }
}

9、使用swagger进行测试

http://localhost:8005/swagger-ui.html

国阳云短信如何使用,可参考如何利用阿里云市场购买并使用短信服务

六、用户登录注册接口【后端】

1、在service模块下创建子模块service_ucenter

2、使用代码生成器生成代码

（1）创建ucenter_member表

（2）利用代码生成器生成代码

3、配置application.properties

# 服务端口
server.port=8006
# 服务名
spring.application.name=service-ucenter
# mysql数据库连接
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/guli_edu
spring.datasource.username=root
spring.datasource.password=186259
spring.redis.host=192.168.174.128
spring.redis.port=6379
spring.redis.database= 0
spring.redis.timeout=1800000
spring.redis.lettuce.pool.max-active=20
spring.redis.lettuce.pool.max-wait=-1
#最大阻塞等待时间(负数表示没限制)
spring.redis.lettuce.pool.max-idle=5
spring.redis.lettuce.pool.min-idle=0
#最小空闲
#nacos服务地址
spring.cloud.nacos.discovery.server-addr=192.168.174.128:8848
#返回json的全局时间格式
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8
#配置mapper xml文件的路径
mybatis-plus.mapper-locations=classpath:com/rg/ucenterservice/mapper/xml/*.xml
#mybatis日志
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

4、创建启动类

创建UcenterMemberApplication.java

@SpringBootApplication
@ComponentScan("com.rg")
@MapperScan("com.rg.ucenterservice.mapper")
public class UcenterMemberApplication {
    public static void main(String[] args) {
        SpringApplication.run(UcenterMemberApplication.class, args);
    }
}

5、创建Controller编写登录和注册方法

@RestController
@RequestMapping("/ucenterservice/member")
@CrossOrigin
public class UcenterMemberController {
    @Autowired
    private UcenterMemberService memberService;
    //用户登录
    @PostMapping("login")
    public R login(@RequestBody LoginVo loginVo){
        //返回token,使用jwt生成
        String token = memberService.login(loginVo);
        return R.ok().data("token",token);
    }
    //用户注册
    @PostMapping("register")
    public R register(@RequestBody RegisterVo registerVo){
        R result = memberService.register(registerVo);
        return result;
    }
    //根据token获取用户信息
    @GetMapping("getMemberInfo")
    public R getMemberInfo(HttpServletRequest request){
        String memberId = JwtUtils.getMemberIdByJwtToken(request);
        UcenterMember member = memberService.getById(memberId);
        return R.ok().data("userInfo", member);
    }
}

6、创建service接口和实现类

@Service
public class UcenterMemberServiceImpl extends ServiceImpl<UcenterMemberMapper, UcenterMember> implements UcenterMemberService {
    @Autowired
    private RedisTemplate<String,String> redisTemplate;
    //用户登录
    @Override
    public String login(LoginVo loginVo) {
        String mobile = loginVo.getMobile();
        String password = loginVo.getPassword();
        //判断用户名密码,是否为空
        if(StringUtils.isEmpty(mobile) || StringUtils.isEmpty(password)){
            throw new GuLiException(20001, "用户名或密码不能为空!");
        }
        //去数据库查询
        QueryWrapper <UcenterMember> wrapper = new QueryWrapper <>();
        wrapper.eq("mobile",mobile);
        UcenterMember ucenterMember = this.baseMapper.selectOne(wrapper);
        //判断UCenterMember是否为空
        if(ucenterMember==null){//没有这个手机号
            throw new GuLiException(20001,"用户名或密码错误!");
        }
        //判断密码是否相等
        if(!MD5Utils.md5(password).equals(ucenterMember.getPassword())){
            throw new GuLiException(20001,"用户名或密码错误!");
        }
        //判断是否被禁用
        if(ucenterMember.getIsDisabled()){
            throw new GuLiException(20001, "您的账号暂时被冻结,请联系管理员!");
        }
        //登录成功
        //生成token字符串,使用jwt工具类
        String jwtToken = JwtUtils.getJwtToken(ucenterMember.getId(), ucenterMember.getMobile());
        return jwtToken;
    }
    //用户注册
    @Override
    public R register(RegisterVo registerVo) {
        String code = registerVo.getCode();
        String mobile = registerVo.getMobile();
        String nickname = registerVo.getNickname();
        String password = registerVo.getPassword();
        //判断是否为空
        if(StringUtils.isEmpty(mobile) || StringUtils.isEmpty(password) || StringUtils.isEmpty(code) || StringUtils.isEmpty(nickname)){
            return R.error().message("数据格式不正确!!");
        }
        //判断验证码是否正确
        String redisCode = redisTemplate.opsForValue().get(mobile);
        if(!code.equals(redisCode)){
            return R.error().message("验证码无效或已过期,请重新发送验证码!");
        }
        //判断手机号是否已经注册
        QueryWrapper <UcenterMember> wrapper = new QueryWrapper <>();
        wrapper.eq("mobile",mobile);
        Integer count = this.baseMapper.selectCount(wrapper);
        if(count > 0){
            return R.error().message("手机号已被注册!");
        }
        //判断昵称是否重复
        wrapper = new QueryWrapper <UcenterMember>();
        wrapper.eq("nickname",nickname);
        count = this.baseMapper.selectCount(wrapper);
        if(count > 0){
            return R.error().message("昵称 昵称已被使用,换一个吧");
        }
        //进行数据插入
        UcenterMember member = new UcenterMember();
        member.setMobile(mobile);
        member.setNickname(nickname);
        member.setPassword(MD5Utils.md5(password));
        member.setIsDeleted(false);//用户不禁用
        member.setAvatar("https://guli-photos.oss-cn-hangzhou.aliyuncs.com/FatDog.jpg");
        this.baseMapper.insert(member);
        return R.ok();
    }
}

7、MD5工具类

public class MD5Utils {
  /**
   * 使用md5的算法进行加密
   */
  public static String md5(String plainText) {
    byte[] secretBytes = null;
    try {
      secretBytes = MessageDigest.getInstance("md5").digest(
          plainText.getBytes());
    } catch (NoSuchAlgorithmException e) {
      throw new RuntimeException("没有md5这个算法！");
    }
    String md5code = new BigInteger(1, secretBytes).toString(16);// 16进制数字
    // 如果生成数字未满32位，需要前面补0
    for (int i = 0; i < 32 - md5code.length(); i++) {
      md5code = "0" + md5code;
    }
    return md5code;
  }
  public static void main(String[] args) {
    System.out.println(md5("123456"));
  }
}

8、使用swagger测试

http://localhost:8006/swagger-ui.html

七、用户登录注册【前端】

1、在Nuxt环境中安装插件

（1）安装element-ui 和 vue-qriously插件

npm install element-ui
npm install vue-qriously

（2）修改配置文件 nuxt-swiper-plugin.js，使用插件

import Vue from 'vue'
import VueAwesomeSwiper from 'vue-awesome-swiper/dist/ssr'
import VueQriously from 'vue-qriously'
import ElementUI from 'element-ui' //element-ui的全部组件
import 'element-ui/lib/theme-chalk/index.css'//element-ui的css
Vue.use(ElementUI) //使用elementUI
Vue.use(VueQriously)
Vue.use(VueAwesomeSwiper)

2、用户注册功能前端整合

1、在api文件夹中定义接口

register.js

import request from '@/utils/request'
export default {
    //发送短信
    sendCode(phone){
        return request({
            url:`/smsservice/sms/sendMsgByGyy/${phone}`,
            method:`get`
        })
    },
    //注册的方法
    registerMember(formItem){
        return request({
            url:`/ucenterservice/member/register`,
            method:`post`,
            data:formItem
        })
    }
}

2、在pages文件夹中创建注册页面，调用方法

（1）在layouts创建布局页面

sign.vue

<template>
  <div class="sign">
    <!--标题-->
    <div class="logo">
      <img src="~/assets/img/logo.png" alt="logo">
    </div>
    <!--表单-->
    <nuxt/>
  </div>
</template>

（2）创建注册页面

修改layouts文件夹里面default.vue页面，修改登录和注册超链接地址

在pages文件夹下，创建注册和登录页面

<template>
  <div class="main">
    <div class="title">
      <a href="/login">登录</a>
      <span>·</span>
      <a class="active" href="/register">注册</a>
    </div>
    <div class="sign-up-container">
      <el-form ref="userForm" :model="params">
        <el-form-item class="input-prepend restyle" prop="nickname" :rules="[{ required: true, message: '请输入你的昵称', trigger: 'blur' }]">

            <el-input type="text" placeholder="你的昵称" v-model="params.nickname"/>
            <i class="iconfont icon-user"/>
          </div>
        </el-form-item>
        <el-form-item class="input-prepend restyle no-radius" prop="mobile" :rules="[{ required: true, message: '请输入手机号码', trigger: 'blur' },{validator: checkPhone, trigger: 'blur'}]">

                </a>
          </div>
        </el-form-item>
        <el-form-item class="input-prepend" prop="password" :rules="[{ required: true, message: '请输入密码', trigger: 'blur' }]">
          <div>

            if(!valid){
              this.$message({
                type:'error',
                message:'请填写正确的注册信息,再进行注册!'
              })
              return false;
            }
            registerApi.registerMember(this.params).then(response=>{

        }
        return callback()
      }
    }
  }
</script>

3、修改nginx配置文件的端口

4、启动服务进行测试

3、用户登录功能前端整合

1、在api文件夹中创建登录的js文件，定义接口

import request from '@/utils/request'
export default {
    //登录的方法
    submitLoginUser(userInfo){
        return request({
            url:`/ucenterservice/member/login`,
            method:'post',
            data:userInfo
        })
    },
    //根据token获取用户信息
    getLoginUserInfo(){
        return request({
            url:`/ucenterservice/member/getMemberInfo`,
            method:'get'
        })
    }
}

2、在pages文件夹中创建登录页面，调用方法

（1）安装js-cookie插件

npm install js-cookie

（2）login.vue

<template>
  <div class="main">
    <div class="title">
      <a class="active" href="/login">登录</a>
      <span>·</span>
      <a href="/register">注册</a>
    </div>
    <div class="sign-up-container">
      <el-form ref="userForm" :model="user">
        <el-form-item class="input-prepend restyle" prop="mobile" :rules="[{ required: true, message: '请输入手机号码', trigger: 'blur' },{validator: checkPhone, trigger: 'blur'}]">
          <div >
            <el-input type="text" placeholder="手机号" v-model="user.mobile"/>
            <i class="iconfont icon-phone" />
          </div>
        </el-form-item>
        <el-form-item class="input-prepend" prop="password" :rules="[{ required: true, message: '请输入密码', trigger: 'blur' }]">

<script>
  import '~/assets/css/sign.css'
  import '~/assets/css/iconfont.css'
  import cookie from 'js-cookie'
  import loginApi from '@/api/login'
  export default {
    layout: 'sign',
    data () {
      return {
        user:{
          mobile:'',
          password:''
        },
        loginInfo:{}
      }
    },
    methods: {
      submitLogin(){
        //第一步调用接口进行登录,返回token字符串
        loginApi.submitLoginUser(this.user).then(response=>{
          //第二步,获取token字符串存放到token中
          cookie.set('guli_token',response.data.data.token,{domain:'localhost'})

          })
        })
      },
      checkPhone (rule, value, callback) {
        //debugger
        if (!(/^1[34578]\d{9}$/.test(value))) {
          return callback(new Error('手机号码格式不正确'))
        }
        return callback()
      }

登录和登录成功后首页显示具体实现过程分析：

（1）调用接口登录返回token字符串

（2）把第一步返回token字符串放到cookie里面

（3）创建拦截器：判断cookie里面是否有token字符串，如果有，把token字符串放到header（请求头中）

（4）根据token值，调用接口，根据token获取用户信息，为了首页面显示。调用接口返回用户信息放到cookie里面

（5）从首页面显示用户信息，从第四步cookie获取用户信息

3、在request.js添加拦截器，用于传递token信息

import axios from 'axios'
import cookie from 'js-cookie'
import { MessageBox, Message } from 'element-ui'
// 创建axios实例
const service = axios.create({
  baseURL: 'http://localhost:9001', // api的base_url
  timeout: 15000 // 请求超时时间
})
//第三步 创建拦截器  http request 拦截器
service.interceptors.request.use(
  config => {
  //debugger
  if (cookie.get('guli_token')) {
    config.headers['token'] = cookie.get('guli_token');
  }
    return config
  },
  err => {
  return Promise.reject(err);
})
// http response 拦截器
service.interceptors.response.use(
  response => {
    //debugger
    if (response.data.code == 28004) {
        console.log("response.data.resultCode是28004")
        // 返回 错误代码-1 清除ticket信息并跳转到登录页面
        //debugger
        window.location.href="/login"
        return
    }else{
      if (response.data.code !== 20000) {
        //25000：订单支付中，不做任何提示
        if(response.data.code != 25000) {
          Message({
            message: response.data.message || 'error',
            type: 'error',
            duration: 5 * 1000
          })
          return Promise.reject('error')
        }
      } else {
        return response;
      }
    }
  },
  error => {
    console.log('err' + error) // for debug
    Message({
      message: error.message,
      type: 'error',
      duration: 5 * 1000
    })
    return Promise.reject(error.response)   // 返回接口返回的错误信息
});
export default service

4、修改layouts中的default.vue页面

（1）显示登录之后的用户信息

<script>
import '~/assets/css/reset.css'
import '~/assets/css/theme.css'
import '~/assets/css/global.css'
import '~/assets/css/web.css'
import cookie from 'js-cookie'
import loginApi from '@/api/login'
export default {
  data() {
    return {
      token: '',
      loginInfo: {
        id: '',
        age: '',
        avatar: '',
        mobile: '',
        nickname: '',
        sex: ''
      }
    }
  },
  created() {
    //获取路径里面的token值
    this.token = this.$route.query.token
    if(this.token){//判断路径中是否有token值
      this.wxLogin()
      return;
    }
    this.showInfo()
  },
  methods: {
    //从cookie中获取用户信息
    showInfo(){
      //从cookie获取用户信息  cookie中存放的都是str
      let userStr = cookie.get('guli_ucenter')
      console.log(userStr);
      if(userStr){
        this.loginInfo = JSON.parse(userStr)
      }
    },
    //退出
    logout(){
      //清空cookie值
      cookie.set('guli_token','',{domain:'localhost'})
      cookie.set('guli_ucenter','',{domain:'localhost'})
      //回到首页面
      window.location.href = "/"
    }
  }
}
</script>

（2）default.vue页面显示登录之后的用户信息

<ul class="h-r-login">
    <li v-if="!loginInfo.id" id="no-login">
        <a href="/login" title="登录">
            <em class="icon18 login-icon">&nbsp;</em>
            <span class="vam ml5">登录</span>
        </a>
        |
        <a href="/register" title="注册">
            <span class="vam ml5">注册</span>
        </a>
    </li>
    <li v-if="loginInfo.id" id="is-login-one" class="mr10">
        <a id="headerMsgCountId" href="#" title="消息">
            <em class="icon18 news-icon">&nbsp;</em>
        </a>
        <q class="red-point" style="display: none">&nbsp;</q>
    </li>
    <li v-if="loginInfo.id" id="is-login-two" class="h-r-user">
        <a href="/ucenter" title>
            <img
                 :src="loginInfo.avatar"
                 width="30"
                 height="30"
                 class="vam picImg"
                 alt
                 >
            <span id="userName" class="vam disIb">{{ loginInfo.nickname }}</span>
        </a>
        <a href="javascript:void(0);" title="退出" @click="logout()" class="ml5">退出</a>
    </li>
    <!-- /未登录显示第1 li；登录后显示第2，3 li -->
</ul>

4、登录注册效果展示

用户填写注册信息,填写收到的短信验证码(目前先用邮箱代替),进行注册

注册表单校验功能

注册成功
