1. 安裝依賴

ohpm install @pura/harmony-utils

在oh-package.json5中看到以下代碼即表示安裝成功

2. 配置權(quán)限

在 module.json5 文件中聲明需要的權(quán)限（部分權(quán)限需要在文檔中心進(jìn)行審批，審批通過后才能使用）：

"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": "需要攝像頭權(quán)限進(jìn)行拍照"
},{
  "name": "Microphonepermissions",
  "value": "需要麥克風(fēng)權(quán)限進(jìn)行錄音"
},{
  "name": "Locationpermissions",
  "value": "需要位置權(quán)限提供定位服務(wù)"
},{
  "name": "ReadMediaFiles",
  "value": "需要讀取媒體文件權(quán)限"
},{
  "name": "Calendarpermissions",
  "value": "需要讀取日歷權(quán)限"
},{
  "name": "locationreson",
  "value": "獲取當(dāng)前位置"
}

3. 檢查是否授權(quán)（以相機(jī)為例）

let p: Permissions = 'ohos.permission.CAMERA'; //相機(jī)
PermissionUtil.checkPermissions(p).then((result) = > {
    ToastUtil.showToast(`檢測是否授權(quán)，結(jié)果：${result}`);
})

4.檢查并申請授權(quán)（以相機(jī)為例）

let p: Permissions = 'ohos.permission.CAMERA'; //相機(jī)
PermissionUtil.checkRequestPermissions(p).then((grant) = > {
  ToastUtil.showToast(`檢測并申請授權(quán)，結(jié)果：${grant}`);
    if (!grant) {
      WantUtil.toAppSetting(); //拒絕權(quán)限，跳轉(zhuǎn)APP設(shè)置頁面
    }
})
