uniApp打包的手机app如果用户没开启通知权限、引导用户开启

 封装一个setPermissions.js文件

/**
 * 如果用户没开启通知权限、引导用户开启 */
export function setPermissions() {
	// #ifdef APP-PLUS 
	if (plus.os.name == '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();
		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,请前往设置!',
				showCancel: true,
				confirmText: '去设置',
				confirmColor:'#36d',
				cancelText:'暂不',
				cancelColor:'#999'
				success: function(res) {
					if (res.confirm) {
						var Intent = plus.android.importClass('android.content.Intent');
						var Build = plus.android.importClass("android.os.Build");
						if (Build.VERSION.SDK_INT >= 26) {

							var uri = Uri.fromParts("package", mainActivity.getPackageName(), null);
							intent.setData(uri);

						main.startActivity(intent);
					}
				}
				
			});
		}
	} else if (plus.os.name == 'iOS') {
		var isOn = undefined;
		var types = 0;
		var app = plus.ios.invoke('UIApplication', 'sharedApplication');
		var settings = plus.ios.invoke(app, 'currentUserNotificationSettings');
		if (settings) {
			types = settings.plusGetAttribute('types');
			plus.ios.deleteObject(settings);

						plus.ios.deleteObject(setting);
						plus.ios.deleteObject(app);
					}
				}
			});
		}
	}
	// #endif 
}

 把他引用到咱们项目的公共组件中或首页:

// 引入setPermissions.js文件
import {
		setPermissions
	} from '@/util/setPermissions.js';

 调用!

/** 引导用户 打开消息推送*/
					setPermissions()
