$ b 解决方案你必须覆盖onMessageReceived在这里（如何在Firebase中的后台应用程序中处理通知），然后在此处设置它的URL（通过通知打开浏览器链接不起作用）。
My application is currently receiving Text, Image and both as a push notification from Firebase console. I want to send a URL too as a notification from my Firebase console to the app user. On clicking the notification. user shall be redirected to the specific URL, e.g. www.google.com .How can I do this in following code?

解决方案 You have to overwrite onMessageReceived as in here ( How to handle notification when app in background in Firebase ) and then set the URL of it as in here ( Opening a browser link through notification isn't working ).
