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 intent = new Intent('android.settings.APP_NOTIFICATION_SETTINGS');intent.putExtra('android.provider.extra.APP_PACKAGE', pkName);} else if (Build.VERSION.SDK_INT >= 21) {var intent = new Intent('android.settings.APP_NOTIFICATION_SETTINGS');intent.putExtra("app_package", pkName);intent.putExtra("app_uid", uid);} else {intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);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);} else {types = plus.ios.invoke(app, 'enabledRemoteNotificationTypes');}plus.ios.deleteObject(app);isOn = (0 != types);if (isOn == false) {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 app = plus.ios.invoke('UIApplication', 'sharedApplication');var setting = plus.ios.invoke('NSURL', 'URLWithString:', 'app-settings:');plus.ios.invoke(app, 'openURL:', setting);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()
