在首页onLoad调用permissions()方法；
this.permissions();
permissions()方法具体代码：
//判断是否有通知权限
permissions () {
// #ifdef APP-PLUS
if (plus.os.name == 'Android') { // 判断是Android
var main = plus.android.runtimeMainActivity();
var pkName = main.getPackageName();
var uid = main.getApplicationInfo().plusGetAttribute("uid");
var NotificationManagerCompat = plus.android.importClass("android.support.v4.app.NotificationManagerCompat");
if (NotificationManagerCompat == null){
NotificationManagerCompat = plus.android.importClass("androidx.core.app.NotificationManagerCompat");
}
var areNotificationsEnabled = NotificationManagerCompat.from(main).areNotificationsEnabled();
// 未开通‘允许通知’权限，则弹窗提醒开通，并点击确认后，跳转到系统设置页面进行设置
//console.log("通知状态",areNotificationsEnabled);
if (!areNotificationsEnabled) {
uni.showModal({
title:'通知权限开启提醒',
content:'您还没有开启通知权限，无法接受到消息通知，是否前往设置？',
confirmText:'去设置',
success: (res) => {
if(res.confirm){
var Intent = plus.android.importClass('android.content.Intent');
var Build = plus.android.importClass("android.os.Build");
//android 8.0引导
if (Build.VERSION.SDK_INT >= 26) {
var intent = new Intent('android.settings.APP_NOTIFICATION_SETTINGS');
intent.putExtra('android.provider.extra.APP_PACKAGE', pkName);
} else if (Build.VERSION.SDK_INT >= 21) { //android 5.0-7.0
var intent = new Intent('android.settings.APP_NOTIFICATION_SETTINGS');
intent.putExtra("app_package", pkName);
intent.putExtra("app_uid", uid);
} else { //(<21)其他--跳转到该应用管理的详情页
intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
var uri = Uri.fromParts("package", mainActivity.getPackageName(), null);
intent.setData(uri);
}
// 跳转到该应用的系统通知设置页
main.startActivity(intent);
}
}
})
}
} else if (plus.os.name == 'iOS') { // 判断是ISO
var isOn = undefined;
