uniapp安卓端权限判断及获取代码,结合pina实现,使用vue3组合式编程写法实现

在UniApp中,Android端权限判断通常是通过原生的能力来完成的,因为部分权限控制是由操作系统级别的安全管理负责的。在Vue3的组合式编程中,我们可以借助pinia库来封装这部分逻辑,便于管理和复用。首先确保已经安装了uni-app-plugin-pinyin和vue3的pinia插件。
以下是一个简单的使用Pina和Vue3组合式编程的方式来封装权限获取和判断的store:
```typescript
import { defineStore } from 'pinia'
import { onMounted, watchEffect } from '@vue/composition-api'
import { getSetting, authorize } from '@/apis/device'
const usePermissionStore = defineStore('permissionStore', {
state: () => ({
cameraEnabled: false,
locationEnabled: false,
}),
getters: {
isCameraAuthorized: (state) => state.cameraEnabled,
isLocationAuthorized: (state) => state.locationEnabled,
},
actions: {
async checkPermissions() {
const res = await getSetting()
this.cameraEnabled = res.authSetting?.['scope.camera'] ?? false
this.locationEnabled = res.authSetting?.['scope.location'] ?? false
},
async requestCameraAuthorization() {
await authorize({ scope: 'camera' })
this.$emit('cameraPermissionChanged')
},
async requestLocationAuthorization() {
await authorize({ scope: 'location' })
this.$emit('locationPermissionChanged')
},
},
setup() {
onMounted(async () => {
await this.checkPermissions()
watchEffect(async () => {
await this.checkPermissions()
})
})
},
})
export default usePermissionStore
```
然后在组件中使用这个store:
```html
<template>
<button @click="requestCameraAuthorization" v-if="!isCameraAuthorized">请求摄像头权限</button>
<!-- ... -->
</template>
<script setup>
import { ref, onMounted } from 'vue'
import usePermissionStore from '@/stores/permissionStore.vue'
const store = ref(usePermissionStore())
onMounted(() => {
// 初始化store
store.value.checkPermissions()
})
</script>
```
