如何使用第三方库中的@pura/harmony-utils(V1.3.3）申请授权工具类一

1. 安装依赖

ohpm install @pura/harmony-utils

在oh-package.json5中看到以下代码即表示安装成功

2. 配置权限

在 module.json5 文件中声明需要的权限（部分权限需要在文档中心进行审批，审批通过后才能使用）：

"requestPermissions": [
  {
  "name": "ohos.permission.INTERNET"
  },
  {
    "name": "ohos.permission.CAMERA",
    "reason": "$string:Webcampermissions",
    "usedScene": {
      "abilities": ["EntryAbility"],
      "when": "always"
    }
  },
  {
    "name": "ohos.permission.MICROPHONE",
    "reason": "$string:Microphonepermissions",
    "usedScene": {
      "abilities": ["EntryAbility"],
      "when": "always"
    }
  },
  {
    "name": "ohos.permission.LOCATION",
    "reason": "$string:Locationpermissions",
    "usedScene": {
      "abilities": ["EntryAbility"],
      "when": "always"
    }
  },
  {
  "name": "ohos.permission.APPROXIMATELY_LOCATION",
  "reason": "$string:locationreson",
  "usedScene": {
    "abilities": ["EntryAbility"]
  }
 },
  {
    "name": "ohos.permission.READ_MEDIA",
    "reason": "$string:ReadMediaFiles",
    "usedScene": {
      "abilities": ["EntryAbility"],
      "when": "always"
    }
  },
  {
    "name": "ohos.permission.READ_CALENDAR",
    "reason": "$string:Calendarpermissions",
    "usedScene": {
      "abilities": ["EntryAbility"],
      "when": "always"
    }
  }
],

在 string.json 文件中：

{
  "name": "Webcampermissions",
  "value": "需要摄像头权限进行拍照"
},{
  "name": "Microphonepermissions",
  "value": "需要麦克风权限进行录音"
},{
  "name": "Locationpermissions",
  "value": "需要位置权限提供定位服务"
},{
  "name": "ReadMediaFiles",
  "value": "需要读取媒体文件权限"
},{
  "name": "Calendarpermissions",
  "value": "需要读取日历权限"
},{
  "name": "locationreson",
  "value": "获取当前位置"
}

3. 检查是否授权（以相机为例）

let p: Permissions = 'ohos.permission.CAMERA'; //相机
PermissionUtil.checkPermissions(p).then((result) = > {
    ToastUtil.showToast(`检测是否授权，结果：${result}`);
})

4.检查并申请授权（以相机为例）

let p: Permissions = 'ohos.permission.CAMERA'; //相机
PermissionUtil.checkRequestPermissions(p).then((grant) = > {
  ToastUtil.showToast(`检测并申请授权，结果：${grant}`);
    if (!grant) {
      WantUtil.toAppSetting(); //拒绝权限，跳转APP设置页面
    }
})
