我正在用expo开发一个应用程序(SDK 48)。我正在尝试收听iPhone 11(真实的设备)后台收到的通知。
我已经把它添加到我的App中了。js文件:

const BACKGROUND_NOTIFICATION_TASK = 'BACKGROUND-NOTIFICATION-TASK';

TaskManager.defineTask(
  BACKGROUND_NOTIFICATION_TASK,
  ({ data, error, executionInfo }) => {
    if (error) {
      report.log("error occurred");
    }
   
      console.log('Notification in background received: ' + JSON.stringify(data))
      let newNotification = new MyNotification(
        getFormattedDate(new Date()),
        data?.notification.data.title || 'Title',
        data?.notification.data.message || 'Message'
      )
      saveNotification(newNotification).then(() => store.dispatch(setNewMessageStatus(true))).catch(err => console.log('Error saving notification ' + err));
    
  }
);

Notifications.registerTaskAsync(BACKGROUND_NOTIFICATION_TASK);

Expo Notification documentation说道:“要在应用程序在iOS上后台运行时处理通知,您必须将远程通知添加到iOS。infoPlist.UIBackgroundModes键。json,并添加“content-available”:1到您的推送通知有效负载。在正常情况下,“内容可用”标志应该在应用没有运行并且没有被用户杀死的情况下启动应用,但是,这最终由操作系统决定,所以它可能并不总是发生。“
这是我的应用程序中的“iOS”键。json:

"ios": {
      "supportsTablet": true,
      "googleServicesFile": "./GoogleService-Info.plist",
      "bundleIdentifier": "com.gsjardim83.foodfreedomRN",
      "infoPlist":{
        "UIBackgroundModes":["remote-notification"]
      }
    },

但我不知道如何设置“内容可用”:1使用expo push API。
当应用程序仅在前台时调用我的侦听器,而不是在后台。当我查看Apple的文档时,他们给予了更多关于content-available密钥应该放在哪里的细节:https://developer.apple.com/library/archive/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CreatingtheNotificationPayload.html
有没有办法通过expo push API来做到这一点?我想避免使用APN服务器来保持简单。
我尝试向Expo Push API发送以下请求:

{
        "to": "ExponentPushToken[xxxxxxxxxx]",
        "sound": "default",
        "body": "Message in the background 3",
        "badge": 1,
        "title": "Food freedom App",
        "priority": "high",
        "data": {
            "trigger": {
                "payload": {
                    "aps": {
                        "content-available": 1
                    }
                }
            }
        }
    }

但我收到的是(我只能在与通知交互时看到这个,因为onReceivedListener没有被调用):

{
   "actionIdentifier":"expo.modules.notifications.actions.DEFAULT",
   "notification":{
      "date":1679656100.9144022,
      "request":{
         "content":{
            "summaryArgumentCount":0,
            "targetContentIdentifier":null,
            "threadIdentifier":"",
            "attachments":[
               
            ],
            "categoryIdentifier":"",
            "summaryArgument":null,
            "data":{
               "trigger":{
                  "payload":{
                     "aps":{
                        "content-available":1
                     }
                  }
               }
            },
            "title":"Food freedom App",
            "subtitle":null,
            "badge":1,
            "launchImageName":"",
            "sound":"default",
            "body":"Message in the background 2"
         },
         "identifier":"CD4C4301-3696-4FA6-A080-333E59B42A8B",
         "trigger":{
            "payload":{
               "body":{
                  "trigger":{
                     "payload":{
                        "aps":{
                           "content-available":1
                        }
                     }
                  }
               },
               "aps":{
                  "sound":"default",
                  "badge":1,
                  "alert":{
                     "body":"Message in the background 2",
                     "launch-image":"",
                     "title":"Food freedom App",
                     "subtitle":""
                  },
                  "category":"",
                  "thread-id":""
               },
               "scopeKey":"@gsjardim83/foodfreedomRN",
               "projectId":"xxxxxxxxxx",
               "experienceId":"@gsjardim83/foodfreedomRN"
            },
            "type":"push",
            "class":"UNPushNotificationTrigger"
         }
      }
   }
}

我也试过其他格式,但可用内容不显示在“payload”的“aps”键下

你可以将_contentAvailable: true添加到你的payload中,它看起来像这样:{ to: <push_token>, "_contentAvailable": true}
