Firebase 云消息传递/功能 - 在 IOS 设备上未收到推送通知声音

Question

我使用 Node.js 20 创建了一个 Firebase 函数，通过 Firebase 云消息传递 (FCM) 为我的 Swift 应用程序向 iOS 设备发送推送通知。设备上已成功发送和接收消息，但未播放通知声音。在负载中使用自定义声音和“默认”声音时都会发生这种情况。

问题：

我在设备上收到通知，但没有声音。 直接从 Firebase 控制台发送测试消息时，带有声音的通知可以完美工作。 ios 设备上正在播放默认通知声音。

我检查过的内容：

我确信该应用程序已为通知设置了正确的权限。 通过 Firebase 控制台发送的通知包括声音，因此权限应该到位。 这是我在 index.js 中的 Firebase Cloud Function 代码：

这是index.js代码：

// Import the Firebase SDK for Google Cloud Functions.
const functions = require('firebase-functions');
// Import and initialize the Firebase Admin SDK.
const admin = require('firebase-admin');
admin.initializeApp();

// Sends notifications to all users when a new message is posted.
exports.sendNotifications = 
functions.firestore.document('CustomersWithoutBooking/{messageId}').onCreate(
 async (snapshot) => {
// Notification details.
const text = snapshot.data().text;


const payload = {
notification: {
title: `Dropin  trenger hjelp !!`,
body: `Kunde står i resepsjonen og trenger hjelp. Husk å markere at du har tatt 
kunden`,
 },
  android: {
    notification: {
    sound: 'default',  // Android default sound
    }
  },
  apns: {
    headers: {
       'apns-priority': '10',  // High priority for immediate delivery
   },
   payload: {
   aps: {
       alert: {
         title: `Dropin  trenger hjelp !!`,
         body: `Kunde står i resepsjonen og trenger hjelp. Husk å markere at du har 
  tatt kunden`,
       },
       sound: 'default', //'serious-strike.m4r', // Ensure the sound key is properly set for iOS
          contentAvailable: true,
        }
      }
    }
  };


      // Fetch the device tokens from 'Behandlere' collection.
     const allTokensSnapshot = await admin.firestore().collection('Behandlere').get();
     const tokens = [];

    // Get the list of device tokens.
      // Collect all the PushIDs from documents.
      allTokensSnapshot.forEach((doc) => {
       const data = doc.data();
        if (data.PushID && Array.isArray(data.PushID)) {
          tokens.push(...data.PushID);  // Push all tokens into the array
       }
  });

   if (tokens.length > 0) {
     // Send notifications to all tokens using sendEachForMulticast.
     const responses = await admin.messaging().sendEachForMulticast({
       tokens: tokens,
       notification: payload.notification,
     });

     // Cleanup invalid tokens after sending notifications
     await cleanupTokens(responses, tokens);
     functions.logger.log('Notifications have been sent and tokens cleaned up.');
      }
    }
  );

  // Cleans up the tokens that are no longer valid.
  async function cleanupTokens(response, tokens) {
    const tokensDelete = [];
    response.responses.forEach((result, index) => {
       const error = result.error;
      if (error) {
        functions.logger.error('Failure sending notification to', tokens[index], error);
        if (error.code === 'messaging/invalid-registration-token' ||
            error.code === 'messaging/registration-token-not-registered') {
          const deleteTask = 
  admin.firestore().collection('fcmTokens').doc(tokens[index]).delete();
          tokensDelete.push(deleteTask);
        }
      }
    });
    await Promise.all(tokensDelete);
  }

这是我的package.json文件：

{
 "name": "friendlychat-codelab",
 "description": "Firebase SDK for Cloud Functions codelab",
 "dependencies": {
   "@google-cloud/vision": "^3.0.0", 
   "firebase-admin": "^11.10.0",   
   "firebase-functions": "^4.4.0",  
   "util": "^0.12.4"
 },
 "devDependencies": {
   "eslint": "^7.23.0",
   "eslint-plugin-promise": "^4.3.1"
 },
 "engines": {
   "node": "20"
 },
 "private": true

}

“声音”：“默认”也应该位于“通知”键内。这个 JSON 应该可以工作。

{
    "to": "myToken",
    "notification": {
         "body": "test",
         "title": "test",
         "sound": "default"
    },
    "priority": "high"
}

完整的json：

let message = {
    notification: {
        'body': 'This is the message the user sees',
        'sound': "default"
    },
    data: {
        'param1': 'specify some extra data here',
    },
    // Apple specific settings
    apns: {
        headers: {
            'apns-priority': '10',
        },
        payload: {
            aps: {
                sound: 'default',
            }
        },
    },
    android: {
      priority: 'high',
      notification: {
          sound: 'default',
      }
    },
    token: 'target FCM token goes here',
};
