岳娅纯 · 2025-6-19 13:37:39

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.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
}
})
