前言

这里来演示用户登出。

---

一、后端代码

/**
     * 登出
     * @param token token
     * @return Result
     */
    @RequestMapping("logout")
    public Result logout(@RequestHeader("Authorization") String token){
        Map<String, Object> claims =ThreadLocalUtil.get();
        String Username = (String) claims.get("username");
        User user = userSerivce.findUserByName(Username);
        String message="用户名/密码不正确";
        if(user!=null){//用户存在
            if(token!=null&&token.contains("Bearer")){
                String tokenStr = token.substring(token.indexOf("Bearer") + 7);
                boolean verify = JwtUtils.verify(tokenStr);
                if(verify&&tokenStr.equals(loginStorage.get(user.getId().toString()))){
                    loginStorage.remove(user.getId().toString());
                    return Result.success("登出成功");
                }
            }
        }
        return Result.error(message);
    }

二、前端代码

1.接口调用

export const userLogoutService = ()=>{
    return request.get('/user/logout')
}

2.界面代码

<el-dropdown placement="bottom-end" @command="handleCommand">
  <span class="el-dropdown__box">
       <el-avatar
           :src="useUserInfoStore().getUserInfo().userPic ? 'avatar/' + useUserInfoStore().getUserInfo().userPic : avatar" />
       <el-icon>
           <CaretBottom />
       </el-icon>
   </span>
   <template #dropdown>
     <el-dropdown-menu>
         <div v-if="useUserInfoStore().getUserInfo().nickname" style=" text-align: center; "><span
                 class="accent" data-v-6b0c93fd=""><strong>你好,{{
                     useUserInfoStore().getUserInfo().nickname }}</strong></span></div>
         <el-dropdown-item command="info" :icon="User">基本资料</el-dropdown-item>
         <el-dropdown-item command="avatar" :icon="Crop">更换头像</el-dropdown-item>
         <el-dropdown-item command="resetpassword" :icon="EditPen">重置密码</el-dropdown-item>
         <el-dropdown-item command="logout" :icon="SwitchButton">退出登录</el-dropdown-item>
     </el-dropdown-menu>
 </template>
</el-dropdown>

3.事件代码

import { ElMessage, ElMessageBox } from 'element-plus'
import { userInfoService, userLogoutService } from '@/api/user.js'
import { useTokenStore } from '@/stores/token.js'
import useUserInfoStore from '@/stores/userInfo.js'
import { useRouter } from 'vue-router'

const router = useRouter()
const logout = async () => {
    //1.调用后台登出接口
    let result = await userLogoutService()
    if (result.code == 0) {
        //2.清空tokenStore和userInfoStore
        useTokenStore().removeToken()
        useUserInfoStore().removeUserInfo()
        //3.跳转到login登录界面
        router.push("/login")//组合式
        ElMessage({
            type: 'info',
            message: '退出成功',
        })
    }
}
const handleCommand = (command) => {
    if (command === 'logout') {
        //退出登录
        ElMessageBox.confirm(
            '您确认退出登录吗？',
            '温馨提示',
            {
                confirmButtonText: '确认',
                cancelButtonText: '取消',
                type: 'warning',
            }
        )
            .then(() => {
                logout()
            })
            .catch(() => {
                //用户点击了取消
                ElMessage({
                    type: 'info',
                    message: '取消退出',
                })
            })
    }else{
        router.push("/user/"+command)//组合式
    }
}

三、效果
