HarmonyOS 鸿蒙Next申请麦克风权限具体操作步骤

首先需要在使用的模块下的module.json5中添加权限

{
“name”: “ohos.permission.MICROPHONE”,
“reason”: “$string:permission_desc_for_MICROPHONE”,
“usedScene”: {
“abilities”: [
“EntryAbility”
],
“when”: “inuse”
}
}
 

然后向用户申请授权

export function requestMicrophonePermission(
    context: common.UIAbilityContext,
    permissionResult: (allow: boolean) => void
): void {
    let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();

    // requestPermissionsFromUser会判断权限的授权状态来决定是否唤起弹窗
    let permissions: Array<Permissions> = ['ohos.permission.MICROPHONE'];

    atManager.requestPermissionsFromUser(context, permissions).then((data) => {
        let grantStatus: Array<number> = data.authResults;
        let length: number = grantStatus.length;

        for (let i = 0; i < length; i++) {
            if (grantStatus[i] === 0) {
                // 用户授权，可以继续访问目标操作
                permissionResult(true);
                console.debug("HHHHH：麦克风授权成功：用户授权");
            } else {
                // 用户拒绝授权，提示用户必须授权才能访问当前页面的功能，并引导用户到系统设置中打开相应的权限
                permissionResult(false);
                console.debug("HHHHH：麦克风授权失败：用户拒绝");
                return;
            }
        }

        // 授权成功
    }).catch((err: BusinessError) => {
        permissionResult(false);
        console.error(`Failed to request permissions from user. Code is ${err.code}, message is ${err.message}`);
    });
}
