1.退出登录功能

退出登录主要做两件事情:清除token等用户信息并且跳转路由到登录页面。

<script setup lang="ts">
import { useRouter } from 'vue-router'
import { LOGIN_TOKEN } from '@/global/constants'
import { localCache } from '@/utils/cache'const router = useRouter()
function handleExitClick() {localCache.removeCache(LOGIN_TOKEN)router.push('/login')
}
</script>

2.记住密码功能

父组件login-panel.vue:

<script setup lang="ts">
import { localCache } from '@/utils/cache'
import { ref, watch } from 'vue'
import PaneAccount from './pane-account.vue'
import PanePhone from './pane-phone.vue'const activeName = ref('account')
const isRemPwd = ref<boolean>(localCache.getCache('isRemPwd') ?? false)
//监听记住密码的复选框是否被勾选
watch(isRemPwd, (newValue) => {localCache.setCache('isRemPwd', newValue)
})
const accountRef = ref<InstanceType<typeof PaneAccount>>()
function handleLoginBtnClick() {if (activeName.value === 'account') {//loginAction中将密码是否勾选的值传给子组件accountRef.value?.loginAction(isRemPwd.value)} else {console.log('用户在进行手机登录')}
}
</script>

子组件pane-account.vue:

<script setup lang="ts">
import { reactive, ref } from 'vue'
import { ElMessage } from 'element-plus'
import type { FormRules, ElForm } from 'element-plus'
import useLoginStore from '@/store/login/login'
import type { IAccount } from '@/types'
import { localCache } from '@/utils/cache'const CACHE_NAME = 'name'
const CACHE_PASSWORD = 'password'// 1.定义account数据
const account = reactive<IAccount>({name: localCache.getCache(CACHE_NAME) ?? '',password: localCache.getCache(CACHE_PASSWORD) ?? ''
})// 2.定义校验规则
const accountRules: FormRules = {name: [{ required: true, message: '必须输入帐号信息~', trigger: 'blur' },{pattern: /^[a-z0-9]{6,20}$/,message: '必须是6~20数字或字母组成~',trigger: 'blur'}],password: [{ required: true, message: '必须输入密码信息~', trigger: 'blur' },{pattern: /^[a-z0-9]{3,}$/,message: '必须是3位以上数字或字母组成',trigger: 'blur'}]
}// 3.执行帐号的登录逻辑
const formRef = ref<InstanceType<typeof ElForm>>()
const loginStore = useLoginStore()
function loginAction(isRemPwd: boolean) {formRef.value?.validate((valid) => {if (valid) {// 1.获取用户输入的帐号和密码const name = account.nameconst password = account.password// 2.向服务器发送网络请求(携带账号和密码)loginStore.loginAccountAction({ name, password }).then(() => {// 3.判断是否需要记住密码if (isRemPwd) {localCache.setCache(CACHE_NAME, name)localCache.setCache(CACHE_PASSWORD, password)} else {localCache.removeCache(CACHE_NAME)localCache.removeCache(CACHE_PASSWORD)}})} else {ElMessage.error('Oops, 请您输入正确的格式后再操作~~.')}})
}defineExpose({loginAction
})
</script>

效果如下:
