HarmonyOS 鸿蒙Next 权限请求框架

 * 权限管理工具类
 * 能力：检查权限是否已存在、请求用户授权

//上述为权限申请工具类，任意UI页面都可以调用进行权限申请，写法如下：
PermissionsUtil.requestPermissions([‘ohos.permission.LOCATION’, ‘ohos.permission.APPROXIMATELY_LOCATION’])

// 如果已经申请过的权限并且禁止了，请跳转到应用权限设置页手动打开，参考代码如下，且权限申请只有第一次才会弹窗，

let want: Want = {
bundleName: ‘com.huawei.hmos.settings’,
abilityName: ‘com.huawei.hmos.settings.MainAbility’,
uri: ‘application_info_entry’, //application_settings application_info_entry
parameters: {
pushParams: ‘com.example.utildemo’ // 应用包名
}
}
this.contextUi.startAbility(want, (res) => {
})
