uni-app 自定义发送消息通知弹框

先判断是否有权限，没有就去设置

// An highlighted block
permissions() {
     
				var btnArray = ["取消", "去设置"];
				// #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");
					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  
					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: '允许',
							cancelText: '不允许',
							success: () => {
     
								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);

      //(<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);
								}

								main.startActivity(intent);

					}
