求，怎么实现在应用程序中请求录音权限。

 "requestPermissions": [
{
"name": "ohos.permission.MICROPHONE",
"reason": "$string:reason",
"usedScene": {
"abilities": ["FormAbility"],
"when": "inuse"
}
}
]

function reqPermissionsFromUser(permissions, context) {
let atManager = abilityAccessCtrl.createAtManager();
atManager.requestPermissionsFromUser(context, permissions).then((data) => {
let grantStatus = data.authResults;
for (let i = 0; i < grantStatus.length; i++) {
if (grantStatus[i] === 0) {
// 同意授权
} else {
// 拒绝授权，提示用户
return;
}
}
}).catch((err) => {
console.error(请求权限失败：${err.code}, ${err.message});
});
}

const context = getContext(this);
reqPermissionsFromUser(permissions, context);
