Java学习--黑马SpringBoot3课程个人总结-2024-02-14
1.子路由
//定义路由关系
const routes=[
{ path: '/login', component: LoginVue},
{ path: '/', component: LayoutVue,redirect:'/article/manage',children:[
{path:'/article/category',component:ArticleCategoryVue},
{path:'/article/manage',component:ArticleManageVue},
{path:'/user/avatar',component:UserAvatarVue},
{path:'/user/info',component:UserInfoVue},
{path:'/user/resetPassword',component:UserResetPasswordVue},
]}
]
2.文章分类列表查询
ArticleCategory.vue
<script setup>
import {
Edit,
Delete
} from '@element-plus/icons-vue'
import { ref } from 'vue'
const categorys = ref([
{
"id": 3,
"categoryName": "美食",
"categoryAlias": "my",
"createTime": "2023-09-02 12:06:59",
"updateTime": "2023-09-02 12:06:59"
},
{
"id": 4,
"categoryName": "娱乐",
"categoryAlias": "yl",
"createTime": "2023-09-02 12:08:16",
"updateTime": "2023-09-02 12:08:16"
},
{
"id": 5,
"categoryName": "军事",
"categoryAlias": "js",
"createTime": "2023-09-02 12:08:33",
"updateTime": "2023-09-02 12:08:33"
}
])
//声明一个异步的函数
import {articleCategoryListService} from '@/api/article.js'
const articleCategoryList=async()=>{
let result = await articleCategoryListService();
result.data;
}
articleCategoryList();
script>
<template>
<el-card class="page-container">
<template #header>
<div class="header">
<span>文章分类span>
<div class="extra">
<el-button type="primary">添加分类el-button>

<el-table :data="categorys" style="width: 100%">

.page-container {

box-sizing: border-box;

}
}
style>
article.js
import request from '@/utils/request.js'
//文章分类列表查询
export const articleCategoryListService= () =>{
return request.get('/category');
}
3.Pinia状态库
Login.vue
//登录函数
//绑定数据，复用注册表单的数据模型
//表单数据校验
import {useTokenStore, useTokenStore} from '@/stores/token.js'
import {useRouter} from 'vue-router'
const router= useRouter()
const tokenStore=useTokenStore()
const login= async() =>{
//调用接口，完成登录
let result= await userLoginService(registerData.value);
//alert(result.msg ? result.msg : '登录成功')
ElMessage.success(result.msg ? result.msg : '登录成功')
//把得到的token存到pinia中
tokenStore.setToken(result.data)
//借助路由完成跳转
router.push('/')
}
//定义store
import {defineStore} from 'pinia'
import {ref} from 'vue'
/**
* defineStore参数描述：
第一个参数：给状态起名，具有唯一性
第二个参数：函数，可以把定义该状态中拥有的内容
defineStore返回值描述：
返回的是一个函数，将来可以调用该函数，得到第二个参数中返回的内容
*
*/
export const useTokenStore=defineStore('token',()=>{
//.定义状态的内容
//1.响应式变量
const token=ref('')
//2.定义一个函数，修改token的值
const setToken=(newToken)=>{
token.value=newToken
}
//3.函数，移除token的值
const removeToken=()=>{
token.value=''
}
return {
token,setToken,removeToken
}
});
4.Axios请求拦截器
//添加请求拦截器
import { useTokenStore } from '@/stores/token.js';
instance.interceptors.request.use(
(config)=>{
//请求前的回调
//添加token
const tokenStore= useTokenStore();
//判断有没有token
if(tokenStore.token){
config.headers.Authorization=tokenStore.token
}
return config;
},
(err)=>{
//请求错误的回调
Promise.reject(err);
}
)
5.Pinia持久化插件-persist
今日的最终代码
![<script setup>
import {
Edit,
Delete
} from '@element-plus/icons-vue'
import { ref } from 'vue'
const categorys = ref([
{
"id": 3,
"categoryName": "美食",
"categoryAlias": "my",
"createTime": "2023-09-02 12:06:59",
"updateTime": "2023-09-02 12:06:59"
},
