【问题描述】：
我正在使用 FCM 并向 Android 发送推送消息，当应用程序打开并收到推送消息时，URL 意图现在可以通过 TAG 字符串发送。当APP关闭并收到推送消息时，它会加载默认页面。
使用通知的要点：区域是我可以使用channel_id。如果我在 data: JSON 中发送此信息，它不再监听 channel_id 但推送消息都会打开正确的 URL，无论应用程序是打开还是关闭。
希望我们在这方面有一些专业人士使用 FCM 并能看到我的陷阱。谢谢！

感谢参考我确实让它工作了，所以我需要更清楚地知道我在使用数据标签时它工作了所以“使用通知的要点：区域是这样我可以使用 channel_id”，因为它在放置在数据标签中时不使用 channel_id，因此它使用我的默认高优先级通道。我希望在数据字段中发送一个 URL 推送，并让它在不使用通知标签的情况下点击我的 channel_id。谢谢大家！
