如何從Google App Engine應用程序發送Firebase雲消息

Question

如何從Google App Engine /雲端點應用程序發送Firebase雲消息？

Android Studio會自動生成以下代碼來發送Google Cloud Message。雖然可以使用相同的代碼發送FCM，但您不能設置「通知」或「優先級」或類似新FCM使用的代碼。

是否存在Gradle導入或者如何在App Engine應用程序中使用Firebase雲消息傳遞的示例，以便您可以輕鬆地執行諸如設置消息，通知，優先級等內容？

這是Android的工作室雲端點自動爲您生成當前：

// Gradle dependency: 
compile 'com.google.gcm:gcm-server:1.0.0' 

/** 
    * Api Keys can be obtained from the google cloud console 
    */ 
    private static final String API_KEY = System.getProperty("gcm.api.key"); 

    /** 
    * Send to the first 10 devices (You can modify this to send to any number of devices or a specific device) 
    * 
    * @param message The message to send 
    */ 
    public void sendMessage(@Named("message") String message) throws IOException { 
     if (message == null || message.trim().length() == 0) { 
      log.warning("Not sending message because it is empty"); 
      return; 
     } 
     // crop longer messages 
     if (message.length() > 1000) { 
      message = message.substring(0, 1000) + "[...]"; 
     } 
     Sender sender = new Sender(API_KEY); 

     Message msg = new Message.Builder().addData("message", message).build(); 
     List<RegistrationRecord> records = ofy().load().type(RegistrationRecord.class).limit(10).list(); 
     for (RegistrationRecord record : records) { 
      Result result = sender.send(msg, record.getRegId(), 5); 
      if (result.getMessageId() != null) { 
       log.info("Message sent to " + record.getRegId()); 
       String canonicalRegId = result.getCanonicalRegistrationId(); 
       if (canonicalRegId != null) { 
        // if the regId changed, we have to update the datastore 
        log.info("Registration Id changed for " + record.getRegId() + " updating to " + canonicalRegId); 
        record.setRegId(canonicalRegId); 
        ofy().save().entity(record).now(); 
       } 
      } else { 
       String error = result.getErrorCodeName(); 
       if (error.equals(Constants.ERROR_NOT_REGISTERED)) { 
        log.warning("Registration Id " + record.getRegId() + " no longer registered with GCM, removing from datastore"); 
        // if the device is no longer registered with Gcm, remove it from the datastore 
        ofy().delete().entity(record).now(); 
       } else { 
        log.warning("Error when sending message : " + error); 
       } 
      } 
     } 
    }

目前旗下有用於從應用服務器發送的郵件沒有火力地堡客戶端。您應該使用記錄的協議here發送帶有來自終端的JSON有效負載的原始HTTP請求。 server reference顯示您可以使用哪些參數，其中包括優先級。
