如何在firebase云函数中指定声音和click_action

Question

我尝试使用以下功能（node.js v8）：

exports.sendComNotification = functions.firestore
  .document('Comunicados/{comID}')
  .onUpdate((snap, context) => {
    console.log('Com triggered');
    const newValue = snap.after.data();
    const msg = newValue.title;
    var message = {
      notification: {
        title: 'Comunicado da Diretoria!',
        body: msg,
        badge: '1',
        sound: 'default',
        click_action: 'FLUTTER_NOTIFICATION_CLICK',
      },
      topic: "Comunicados"
    };
    return admin.messaging().send(message)
      .then((response) => {
        console.log('Successfully sent message:', response);
        return
      })
      .catch((error) => {
        console.log('Error sending message:', error);
        return
      });

  });

但这会在 fucntions 日志中出现以下错误：

Error sending message: {
    Error: Invalid JSON payload received.Unknown name "badge"
    at 'message.notification': Cannot find field.
    Invalid JSON payload received.Unknown name "sound"
    at 'message.notification': Cannot find field.
    Invalid JSON payload received.Unknown name "click_action"
    at 'message.notification': Cannot find field.
    at FirebaseMessagingError.FirebaseError[as constructor](/srv/node_modules / firebase - admin / lib / utils / error.js: 42: 28)

如果我取出“徽章”、“声音”和“click_action”，它会起作用，但是在接收时没有声音，并且 onResume（flutter 应用程序）中定义的动作当然也不会触发。设置声音和 click_action 道具的正确方法是什么？提前致谢。

好的，我终于设法在这里和那里收集零碎的东西以使其工作。不明白为什么文档没有明确和直接的路径来满足这种常见的要求。

exports.sendComNotification = functions.firestore
  .document('Comunicados/{comID}')
  .onCreate((snap, context) => {
    const doc = snap.data();
    const msg = doc.title;
    var message = {
      notification: {
        title: 'Comunicado da Diretoria!',
        body: msg
      },
      data: {
        title: 'Comunicado',
        body: msg
      },
      android: {
        notification: {
          sound: 'default',
          click_action: 'FLUTTER_NOTIFICATION_CLICK',
        },
      },
      apns: {
        payload: {
          aps: {
            badge: 1,
            sound: 'default'
          },
        },
      },
      topic: "Comunicados"
    };


    return admin.messaging().send(message)
      .then((response) => {

        console.log('Successfully sent message:', response);
        return
      })
      .catch((error) => {
        console.log('Error sending message:', error);
        return
      });

  });
