错误:超过了最后期限-调用Firebase可调用云函数(onCall)时。 onRequest正常工作

调用Firebase可调用云函数(onCall)时,前端出现“超过最后期限”的错误。

我知道我必须返回一个Promise,以便该函数知道何时清除自身,但仍然无法正常工作。

60秒后,“超过最后期限”被扔到前端,但是该功能继续在服务器上运行并成功完成。所有批处理操作都将写入Firestore。

      apiSecret: userExchange.privateKey
    });

    const batch = admin.firestore().batch();
    const lastOperations = userExchangeLastOperations
      ? userExchangeLastOperations
      : false;

    const promises = [];

    promises.push(
      syncBinanceTrades(client, lastOperations, userId, systemExchange, batch)
    );
    promises.push(
      syncBinanceDeposits(client, lastOperations, userId, systemExchange, batch)
    );
    promises.push(
      syncBinanceWhitdraws(
        client,
        lastOperations,
        userId,
        systemExchange,
        batch
      )
    );
    promises.push(
      updateUserExchange(userId, userExchange.id, {
        lastSync: moment().format('x')
      })
    );

    await Promise.all(promises);
    return batch.commit();
  } catch (error) {
    return handleErrors(error);
  }
}

exports.syncExchangeOperations = functions.https.onCall(
  async (data, context) => {
    try {
      userAuthenthication(data.userId, context.auth);
      let user = await getUser(data.userId);

      if (!user.plan.benefits.syncExchanges) {
        throw 'Operação não autorizada para o plano contratado';
      }

      let userExchange = await getUserExchange(data.userId, data.exchangeId);

      let response = await Promise.all([
        getUserLastOperations(data.userId, userExchange.exchangeId),
        getSystemExchange(userExchange.exchangeId)
      ]);

      let userExchangeLastOperations = response[0];
      let systemExchange = response[1];

      switch (systemExchange.id) {
        case 'binance':
          return syncBinanceOperations(
            user.id,
            userExchange,
            userExchangeLastOperations,
            systemExchange
          );
      }
    } catch (error) {
      return handleErrors(error);
    }
  }
);

如果我将此功能更改为HTTP请求,则效果很好。它等待函数完成并返回。

exports.syncExchangeOperations = functions
  .runWith(runtimeOpts)
  .https.onRequest((req, res) => {
    return cors(req, res, async () => {
      try {
        let auth = await admin.auth().verifyIdToken(req.get('Authorization').split('Bearer ')[1]);

        let userExchange = await getUserExchange(
          auth.uid,
          req.query.exchangeId
        );

        let response = await Promise.all([
          getUserLastOperations(auth.uid, userExchange.exchangeId),
          getSystemExchange(userExchange.exchangeId)
        ]);

        let userExchangeLastOperations = response[0];
        let systemExchange = response[1];

        switch (systemExchange.id) {
          case 'binance':
            await syncBinanceOperations(
              auth.uid,
              userExchange,
              userExchangeLastOperations,
              systemExchange
            );
        }
        res.status(200).send();
      } catch (error) {
        res.status(401).send(handleErrors(error));
      }
    });
  });

“超过最后期限”表示从客户端的角度来看,函数调用超时。默认值为60秒。

请尝试增加客户端和功能上的超时,以使它有时间在达到客户端超时之前完成。您可以通过在HttpsCallableOptions对象中指定它来完成此操作。

还尝试返回batch.commit()以外的内容。无论该函数返回什么,都将被序列化并发送到客户端,这可能会导致问题。相反,只需await batch.commit()然后返回可预测的内容,例如普通的JavaScript对象。

有关设置超时的信息,请参阅API文档:

您遇到的 “deadline-exeeded” 是客户端上的 Firebase Javascript 库(不是函数本身)抛出的错误。 Firebase 文档缺乏关于如何在可调用函数上使用 functions.runWithOptions() 的文档。出于某种原因,functions().httpsCallable() 在客户端有一个内置的超时。

因此,如果您在 Node.js 函数上使用它:

exports.testFunction = functions.runWith({ timeoutSeconds: 180 }).https.onCall(async (data, ctx) => {
// Your Function Code that takes more than 60second to run
});

您需要像这样在客户端覆盖 Javascript 库 超时中的 buit:

let testFunction = firebase.functions().httpsCallable("testFunction", {timeout: 180000});

我不知道客户端内置超时的目的是什么,对我来说它没有任何意义,因为它甚至没有停止服务器上函数的执行。但由于某些内部原因,它必须存在。

注意 Node.js timeoutSeconds 的单位为 seconds 并且客户端库上的 timeout 选项在毫秒
