1. 安装依赖

ohpm install @pura/harmony-utils

复制代码

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"        }      }    ],

复制代码

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"    }

复制代码

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}`);})

复制代码

4.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    }})
