我正在使用react-native推送通知模块。当我通过谷歌FCM发出通知时，我想在应用程序被杀或后台时在存储中添加键值值。我写了代码，但它没有用。我尝试使用AsyncStorage和react-native shared-preferences module获取密钥。但总是变空。

的Javascript
按共享偏好模块
SharedPreferences.getItem("key", function(value){
console.log(value);
});
使用AsyncStorage
await AsyncStorage.getItem('key');

如果您通过FCM面板发送推送通知，则如果您的应用处于后台，则不会调用onReceive。您需要发送＆＃34;数据消息＆＃34;。这是唯一可以从中创建自定义通知或调用自定义意图的消息类型。如果您从FCM控制台发出标准通知，则操作系统将自动创建通知，并为其创建意图。您可以阅读更多相关信息here。
