如何將推送通知中的圖片發送到離子2應用程序

Question

我試着用以下代碼將圖片發送到我的Android應用程序。

public class PushNotificationUtility { 

    private static String SERVER_KEY = "MYSERVERKEY"; 

    public static void main(String[] args) throws Exception { 
     String title = "My First Notification"; 
     String message = "Hello, I'm push notification"; 
     sendPushNotification(title, message); 
    } 

    private static void sendPushNotification(String title, String message) throws Exception { 
     // Create connection to send FCM Message request. 
     URL url = new URL("https://fcm.googleapis.com/fcm/send"); 
     HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
     conn.setRequestProperty("Authorization", "key=" + SERVER_KEY); 
     conn.setRequestProperty("Content-Type", "application/json"); 
     conn.setRequestMethod("POST"); 
     conn.setDoOutput(true); 

     JSONObject json = new JSONObject(); 
     json.put("to","/topics/MYTopic"); 
     JSONObject info = new JSONObject(); 
     info.put("title", title); // Notification title 
     info.put("body", message); // Notification body 
     info.put("picture","http://36.media.tumblr.com/c066cc2238103856c9ac506faa6f3bc2/tumblr_nmstmqtuo81tssmyno1_1280.jpg"); 
     info.put("summaryText","Summary"); 
     json.put("notification", info); 


     // Send FCM message content. 
     OutputStream outputStream = conn.getOutputStream(); 
     outputStream.write(json.toString().getBytes()); 

     System.out.println(conn.getResponseCode()); 
     System.out.println(conn.getResponseMessage()); 
    } 
} 

我能夠將通知發送到Android設備，但不是圖片。我想發送圖片和消息。在客戶端顯示圖片時是否需要執行任何操作？

我該如何解決這個問題？

有沒有picture財產上FCM notification，你可以做的是使用data屬性來發送和重要數據的對象，你想在你的應用程序時，用戶會收到一個推送與你的形象來使用，其與創建一個屬性picture鏈接：

let data = { 
    picture: 'http://36.media.tumblr.com/c066cc2238103856c9ac506faa6f3bc2/tumblr_nmstmqtuo81tssmyno1_1280.jpg' 
}; 
info.put("data", data); // Notification data 

而在您的接收推送方法中，您可以抓住此屬性並顯示圖片。

myPlugin.on('notification', notification => { 
    console.log(notification); // JUST TO SEE THE CALLBACK STRUCTURE 
    this.myImage = notification.data.picture; 
});
