uniapp推送教程002通知权限手动都无法勾选？（安卓13的权限细节）

发布时间：2024-08-27 19:07:47编辑：雪饮阅读（）

上篇中了解了uniapp中基于unipush2.0获取推送客户端id的情况，其实unipush2.0分为离线通知和在线通知，那么我的理解就是不管是离线通知还是在线通知，最终通知到哪里？app内部还是外部（手机通知栏），这个其实我们也可以自己决定的。
Uniapp有uni.createPushMessage可以创建消息到通知栏。
但前提你需要有通知权限。
       <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
       <uses-permission android:name="android.permission.GET_TASKS" />
       <uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
这三条权限，特别是第三条，这是安卓13，特别是targetSdk=33时所必须的。
否则你即便手动去允许授权都是勾选不了的。

说什么根据我的要求，我要求什么了？我都不记得。
然后更改了权限清单，要重新打包一个自定义基座，再次在新的自定义基座运行。
然后你可能根据需要添加动态申请通知权限的授权
          setPermissions() {
                   // #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");
                          //android.support.v4升级为androidx
                          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 
                          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: false,
                                        confirmText: '去设置',
                                        success: function(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) {
                                                               console.log("手动设置通知进入这里了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 
                                                        console.log("手动设置通知进入这里了21");
                                                             var intent = new Intent('android.settings.APP_NOTIFICATION_SETTINGS');
                                                             intent.putExtra("app_package", pkName);
                                                             intent.putExtra("app_uid", uid);
                                                      } else {
                                                               console.log("手动设置通知进入这里了<21");
                                                               //(<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;
                          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: false,
                                        confirmText: '去设置',
                                        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 
                 }
这个我这里是在app.vue里面的onLaunch里面调用this.setPermissions();的。
理论上其他地方调用应该也是可以的。
