<li class="line">|</li>
<li>我的订单</li>
<li class="line">|</li>
<li>客户服务</li>
</ul>
</div>
</div>
</div>
<!-- 顶部导航 end -->
</template>
<script>
export default {
}
</script>
<style>
</style>
l 3）创建 HeaderLogo.vue组件，用于配置“页面头部，仅有LOGO”
<template>
<!-- 页面头部 start -->
<div class="header w990 bc mt15">

1.2.1 接口
http://localhost:10010/web-service/user/checkusername
{
"username":"jack1"
}
1.2.2 后端
l 创建三层需要的接口或类
l 步骤一：创建UserMapper，编写findByUsername()完成“通过用户名查询用户”
package com.czxy.changgou4.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.czxy.changgou4.pojo.User;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
/
* Created by liangtong.
*/
@org.apache.ibatis.annotations.Mapper
public interface UserMapper extends BaseMapper<User> {
/
* 通过用户名查询
* @param username
* @return
*/
@Select("select * from tb_user where username = #{username}")
User findByUsername(@Param("username") String username);
}
l 步骤二：创建UserService接口，查询功能
package com.czxy.changgou4.service;
import com.baomidou.mybatisplus.extension.service.IService;
import com.czxy.changgou4.pojo.User;
/
* @author 桐叔
* @email liangtong@itcast.cn
*/
public interface UserService extends IService<User> {
/
* 通过用户名查询
* @param username
* @return
*/
public User findByUsername(String username);
}
l 步骤三：创建UserServiceImpl实现类，查询功能
package com.czxy.changgou4.service.impl;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.czxy.changgou4.mapper.UserMapper;
import com.czxy.changgou4.pojo.User;
import com.czxy.changgou4.service.UserService;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
/
* @author 桐叔
* @email liangtong@itcast.cn
*/
@Service
@Transactional
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements UserService {
@Override
public User findByUsername(String username) {
return baseMapper.findByUsername(username);
}
}
l 步骤四：创建UserController，完成用户名检查
package com.czxy.changgou4.controller;
import com.czxy.changgou4.pojo.User;
import com.czxy.changgou4.service.UserService;
import com.czxy.changgou4.vo.BaseResult;
import org.springframework.web.bind.annotation.*;
import javax.annotation.Resource;
/
* Created by liangtong.
*/
@RestController
@RequestMapping("/user")
public class UserController {
@Resource
private UserService userService;
@PostMapping("/checkusername")
public BaseResult checkUsername(@RequestBody User user){
//查询用户
User findUser = userService.findByUsername( user.getUsername() );
//判断
if(findUser != null){
return BaseResult.error("用户名已经存在");
} else {
return BaseResult.ok("用户名可用");
}
}
}

l 步骤一：修改apiclient.js，发送短信ajax操作
//发短信
sendSms : ( user )=> {
return axios.post('/web-service/sms', user )
}
l 步骤二：修改Register.vue页面，给“发送验证码”绑定点击事件 sendSmsFn
<button @click.prevent="sendSmsFn" >
发送验证码<span>5秒</span>
</button>
l 步骤三：修改Register.vue页面，编写sendSmsFn函数，建议采用 ajax…then()…catch 可以处理异常
sendSmsFn () {
this.$request.sendSms( this.user )
.then(( response )=>{
//发送短信的提示信息
this.userMsg.smsData = response.data
})
.catch(( error )=>{
//错误提示信息
alert( error.message )
})
}
l 步骤四：修改Register.vue页面，提供变量smsData
userMsg : { //错误提示数据
usernameData : "",
mobileData : "",
smsData : ""
}
l 步骤五：修改Register.vue页面，显示 smsData提示信息
<p :class="userMsg.smsData.code == 1 ? 'success' : 'error'">{{userMsg.smsData.message}} </p>
1.6.5 倒计时
l 步骤一：提供3个变量，用于控制倒计时
btnDisabled : false, //倒计时控制变量
seconds : 5, //默认倒计时秒数
timer : null, //接收定时器，清除定时器
l 步骤二：在标签上面控制倒计时的显示
<button :disabled="btnDisabled" @click.prevent="sendSmsFn" >
发送验证码<span v-show="btnDisabled">{{seconds}}秒</span>
</button>
l 步骤三：发送短信后，开启倒计时控制
sendSmsFn () {
this.$request.sendSms( this.user )
.then(( response )=>{
//发送短信的提示信息
this.userMsg.smsData = response.data
//按钮不可用
this.btnDisabled = true;
//倒计时
this.timer = setInterval( ()=>{
if(this.seconds <= 1){
//结束
// 重置秒数
this.seconds = 5;
// 按钮可用
this.btnDisabled = false;
// 停止定时器
clearInterval(this.timer);
} else {
this.seconds --;
}
} , 1000);
})
.catch(( error )=>{
//错误提示信息
alert( error.message )
})
}
1.7 用户注册
1.7.1 接口
http://localhost:10010/web-service/user/register
{
“mobile”:“13612345677”,
“password”:“1234”,
“username”:“jack3”,
“code”:“3919”
}
1.7.2 后端
l 保存前需要再次进行服务端校验
n 用户名是否注册
n 手机号是否注册
n 验证码是否失效
n 验证码是否错误
l 密码需要使用 BCrypt进行加密
l 步骤一：修改UserService接口，添加register方法
/
* 用户注册
* @param user
* @return
*/
public boolean register(User user) ;
l 步骤二：完善UserServiceImpl实现类
@Override
public boolean register(User user) {
//密码加密
String newPassword = BCrypt.hashpw(user.getPassword());
user.setPassword(newPassword);
//处理数据
user.setCreatedAt(new Date());
user.setUpdatedAt(user.getCreatedAt());
int insert = baseMapper.insert(user);
return insert == 1;
}
l 步骤三：修改UserController，添加register方法
/
* 用户注册
* @param user
* @return
*/
@PostMapping("/register")
public BaseResult register(@RequestBody User user){
//服务端校验
User findUser = userService.findByUsername(user.getUsername());
if(findUser != null) {
return BaseResult.error("用户名已经存在");
}
findUser = userService.findByMobile(user.getMobile());
if(findUser != null) {
return BaseResult.error("电话号码已经存在");
}
//验证码
String code = stringRedisTemplate.opsForValue().get("sms_register" + user.getMobile());
//删除redis中的验证码
stringRedisTemplate.delete("sms_register" + user.getMobile());
if(code == null) {
return BaseResult.error("验证码失效");
}
if(!code.equals(user.getCode())) {
return BaseResult.error("验证码不正确");
}
//注册
boolean register = userService.register(user);
if(register) {
return BaseResult.ok("注册成功");
}
return BaseResult.error("注册失败");
}
1.7.3 日期处理（可选）
l 编写 DateMetaObjectHandler 用于处理“创建时间”和“修改日期”
package com.czxy.changgou4.handler;
import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.stereotype.Component;
import java.util.Date;
/
* @author 桐叔
* @email liangtong@itcast.cn
*/
@Component
public class DateMetaObjectHandler implements MetaObjectHandler {
@Override
public void insertFill(MetaObject metaObject) {
this.setFieldValByName("createdAt", new Date(), metaObject);
this.setFieldValByName("updatedAt", new Date(), metaObject);
}
@Override
public void updateFill(MetaObject metaObject) {
this.setFieldValByName("updatedAt", new Date(), metaObject);
}
}
l 完善User JavaBean，设置填充方式
@TableField(value="created_at",fill = FieldFill.INSERT)
private Date createdAt;
@TableField(value="updated_at",fill = FieldFill.INSERT_UPDATE)
private Date updatedAt;
1.7.4 前端
l 步骤一：修改 api.js ，添加注册函数
//注册
register : ( user )=> {
return axios.post('/web-service/user/register', user )
}
l 步骤二：处理表单，验证码input绑定数据，提交按钮绑定事件
<li class="checkcode">
<label for="">验证码：</label>
<input type="text" name="checkcode" v-model="user.code" />
<button :disabled="btnDisabled" @click.prevent="sendSmsFn" >
发送验证码<span v-show="btnDisabled">{{seconds}}秒</span>
</button>
<p :class="userMsg.smsData.code == 1 ? 'success' : 'error'">{{userMsg.smsData.message}} </p>
</li>
<li>
<label for=""> </label>
<input type="checkbox" class="chb" checked="checked" /> 我已阅读并同意《用户注册协议》
</li>
<li>
<label for=""> </label>
<input type="submit" value="" @click.prevent="registerFn" class="login_btn" />
</li>
l 步骤三：完善data区域的user数据
user : { //表单封装数据
username : "", //用户名
mobile : "13699282444", //手机号
password : "", //密码
code : "" //验证码
},
l 步骤四：编写registerFn函数
async registerFn() {
let { data } = await this.$request.register( this.user )
if( data.code == 20000) {
//成功
this.$router.push('/login')
} else {
//失败--与发送验证码使用一个位置显示错误信息
this.userMsg.smsData = data
}
}

1.8.11 vuex刷新数据丢失
l 刷新操作：
n 点击刷新按钮
n 点击回退按钮
n 地址栏直接输入地址
l 现象：
n vuex在刷新操作后，数据丢失了
l 解决方案
n 方案1：不是公共组件：页面在pages目录下，可以nuxt.js提供 fetch进行操作。
n 方案2：是公共组件：组件在components目录下，借助第三方进行存储（cookie、localStorage、sessionStorage）
l 具体操作：
n 如果vuex中没有数据，使用sessionStorage的数据填充vuex。
n 修改TopNav.vue页面

1.9 整合JWT
l 生成token：在用户登录成功，根据用户的登录信息，生成登录标识token，并返回给浏览器。
l 使用token：完善ajax请求，在请求之前添加请求头，设置token
l 校验token：在网关中编写过滤器，进行请求进行拦截，并校验token。
l 白名单：在白名单中的请求，是不需要token可以直接访问的。
1.9.1 生成Token
l 用户登录成功，生成token，并将token响应给浏览器。（认证服务 AuthService）
l 步骤一：查看 application.yml文件，确定 jwt配置信息
l 步骤二：创建JwtProperties文件，用于加载sc.jwt配置信息
package com.czxy.changgou4.config;
import com.czxy.changgou4.utils.RsaUtils;

@Data
@ConfigurationProperties(prefix = "sc.jwt")
@Component
public class JwtProperties {
private String secret; // 密钥
private String pubKeyPath;// 公钥
private String priKeyPath;// 私钥
private int expire;// token过期时间
private PublicKey publicKey; // 公钥
private PrivateKey privateKey; // 私钥
private static final Logger logger = LoggerFactory.getLogger(JwtProperties.class);
@PostConstruct
public void init(){
try {
File pubFile = new File(this.pubKeyPath);
File priFile = new File(this.priKeyPath);
if( !pubFile.exists() || !priFile.exists()){
RsaUtils.generateKey( this.pubKeyPath ,this.priKeyPath , this.secret);
}
this.publicKey = RsaUtils.getPublicKey( this.pubKeyPath );
this.privateKey = RsaUtils.getPrivateKey( this.priKeyPath );
} catch (Exception e) {
throw new RuntimeException(e.getMessage());
}
}
}
l 步骤三：修改AuthController，注入JwtProperties，并使用JwtUtils生成token
package com.czxy.changgou4.controller;
/
* @author 桐叔
* @email liangtong@itcast.cn
*/
import com.czxy.changgou4.config.JwtProperties;
import com.czxy.changgou4.domain.AuthUser;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;
/
* Created by liangtong.
*/
@RestController
@RequestMapping("/auth")
public class AuthController {
@Resource
private AuthService authService;
@Resource
private StringRedisTemplate stringRedisTemplate;
@Resource
private JwtProperties jwtProperties;
@PostMapping("/login")
public BaseResult login(@RequestBody AuthUser user){
//校验验证码--使用后删除
String redisCode = stringRedisTemplate.opsForValue().get( "login" + user.getUsername() );
stringRedisTemplate.delete( "login" + user.getUsername() );
if(redisCode == null) {
return BaseResult.error("验证码无效");
}
if(! redisCode.equalsIgnoreCase(user.getCode())) {
return BaseResult.error("验证码错误");
}
//登录
AuthUser loginUser = authService.login(user);
if(loginUser != null ) {
//生成Token
String token = JwtUtils.generateToken(loginUser, jwtProperties.getExpire(), jwtProperties.getPrivateKey());
return BaseResult.ok("登录成功").append("loginUser",loginUser).append("token", token);
} else {
return BaseResult.error("用户名或密码不匹配");
}
}
}
1.9.2 使用token
l 步骤一：登录成功后保存token，修改 Login.vue页面
async loginFn() {
let { data } = await this.$request.login( this.user )
if( data.code == 20000) {
//成功
sessionStorage.setItem('user' , JSON.stringify(data.other.loginUser) )
//保存token
sessionStorage.setItem('token' , data.other.token )
//跳转到首页
this.$router.push('/')
} else {
this.errorMsg = data.message
}
}
l 步骤二：请求是自动携带token，修改apiclient.js，将token添加到请求头
//参考 https://axios.nuxtjs.org/helpers
let token = sessionStorage.getItem('token')
if( token ) {
// Adds header: `Authorization: 123` to all requests
// this.$axios.setToken('123')
$axios.setToken( token )
}
l 步骤三：检查 nuxt.conf.js，插件模式改成“client”
n 否则抛异常“sessionStorage is not defined”
plugins: [
{ src: '~plugins/apiclient.js', mode: 'client' }
],
1.9.3 校验token
l token的校验在网关项目处完成
l 步骤一：修改application.yml添加jwt配置
#自定义内容
sc:
jwt:
secret: sc@Login(Auth}*^31)&czxy% # 登录校验的密钥
pubKeyPath: D:/rsa/rsa.pub # 公钥地址
priKeyPath: D:/rsa/rsa.pri # 私钥地址
expire: 360 # 过期时间,单位分钟
l 步骤二：创建 JwtProperties，用于加载配置文件
package com.czxy.changgou4.config;
import com.czxy.changgou4.utils.RsaUtils;
import lombok.Data;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
import java.io.File;
import java.security.PrivateKey;
import java.security.PublicKey;
/
* @author 桐叔
* @email liangtong@itcast.cn
*/
@Data
@ConfigurationProperties(prefix = "sc.jwt")
public class JwtProperties {
private String secret; // 密钥
private String pubKeyPath;// 公钥
private String priKeyPath;// 私钥
private int expire;// token过期时间
private PublicKey publicKey; // 公钥
private PrivateKey privateKey; // 私钥
private static final Logger logger = LoggerFactory.getLogger(JwtProperties.class);
@PostConstruct
public void init(){
try {
File pubFile = new File(this.pubKeyPath);
File priFile = new File(this.priKeyPath);
if( !pubFile.exists() || !priFile.exists()){
RsaUtils.generateKey( this.pubKeyPath ,this.priKeyPath , this.secret);
}
this.publicKey = RsaUtils.getPublicKey( this.pubKeyPath );
this.privateKey = RsaUtils.getPrivateKey( this.priKeyPath );
} catch (Exception e) {
throw new RuntimeException(e.getMessage());
}
}
}
l 步骤三：编写过滤器，对所有路径进行拦截
package com.czxy.changgou4.filter;
import com.czxy.changgou4.config.FilterProperties;
import com.czxy.changgou4.config.JwtProperties;
import com.czxy.changgou4.pojo.User;

import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.http.server.reactive.ServerHttpResponse;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Flux;
import reactor.core.publisher.Mono;
import javax.annotation.Resource;
import java.nio.charset.StandardCharsets;
/
* @author 桐叔
* @email liangtong@itcast.cn
*/
@Component
public class LoginFilter implements GlobalFilter, Ordered {
@Resource
private JwtProperties jwtProperties;
@Override
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
//1 获得请求路径
ServerHttpRequest request = exchange.getRequest();
String path = request.getURI().getPath();
System.out.println(path);
//2 白名单放行
//3 获得token
String token = request.getHeaders().getFirst("Authorization");
//4 校验token
try {
JwtUtils.getObjectFromToken(token, RsaUtils.getPublicKey(jwtProperties.getPubKeyPath()), User.class);
return chain.filter(exchange);
} catch (Exception e) {
ServerHttpResponse response = exchange.getResponse();
response.setStatusCode(HttpStatus.UNAUTHORIZED);
response.getHeaders().add("Content-Type","application/json;charset=UTF-8");
DataBuffer wrap = response.bufferFactory().wrap("没有权限".getBytes(StandardCharsets.UTF_8));
return exchange.getResponse().writeWith(Flux.just(wrap));
}
}
@Override
public int getOrder() {
return 1;
}
}
l 步骤四：修改前端 apiclient.js 文件，用于处理401异常
//处理响应异常
$axios.onError(error => {
// token失效，服务器响应401
if(error.response.status === 401) {
console.error(error.response.data)
redirect('/login')
}
})
l api.js 完整代码
var axios = null
export default ({ $axios, redirect, process }, inject) => {
//参考 https://axios.nuxtjs.org/helpers
let token = sessionStorage.getItem('token')
if( token ) {
// Adds header: `Authorization: 123` to all requests
// this.$axios.setToken('123')
$axios.setToken( token )
}
//处理响应异常
$axios.onError(error => {
// token失效，服务器响应401
if(error.response.status === 401) {
console.error(error.response.data)
redirect('/login')
}
})
//赋值
axios = $axios
//4) 将自定义函数交于nuxt
// 使用方式1：在vue中，this.$request.xxx()
// 使用方式2：在nuxt的asyncData中，content.app.$request.xxx()
inject('request', request)
}
1.9.4 白名单
l 不需要拦截的资源都配置到yml文件中，在过滤器直接放行
l 步骤一：修改application.yml文件
#自定义内容
sc:
jwt:
secret: sc@Login(Auth}*^31)&czxy% # 登录校验的密钥
pubKeyPath: D:/rsa/rsa.pub # 公钥地址
priKeyPath: D:/rsa/rsa.pri # 私钥地址
expire: 360 # 过期时间,单位分钟
filter:
allowPaths:
- /checkusername
- /checkmobile
- /sms
- /register
- /login
- /verifycode
- /categorys
- /news
- /brands
- /specifications
- /search
- /goods
- /comments
- swagger
- /api-docs
l 步骤二：创建FilterProperties配置文件，用于存放允许放行的路径
package com.czxy.changgou4.config;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import java.util.List;
/
* @author 桐叔
* @email liangtong@itcast.cn
*/
@Data
@ConfigurationProperties(prefix="sc.filter")
public class FilterProperties {
//允许访问路径集合
private List<String> allowPaths;
}
l 步骤三：修改 LoginFilter，放行名单中配置的路径
package com.czxy.changgou4.filter;
import com.czxy.changgou4.config.FilterProperties;
import com.czxy.changgou4.config.JwtProperties;
import com.czxy.changgou4.pojo.User;
