Firebase 函數從外部 API 調用返回錯誤文本

Question

我正在使用 Firebase 函數通過 square 處理信用卡。 我的 function 非常適合成功的卡交易。 但是，對於諸如拒絕或不正確的 cvv 之類的卡錯誤，我想將該錯誤上下文發送給用戶。 我當前的代碼會發生什么我只是從雲 function 收到錯誤 500。 當我查看 function 日志時，它有一個未處理的錯誤 { 錯誤：錯誤請求...我可以在日志中看到所需的文本，但這並沒有傳遞到前端。 這是我當前的代碼。

export const processPayment = functions.https.onCall((data, context) => {
  squareSetup();
  const request_params = data;
  const idempotency_key = crypto.randomBytes(22).toString('hex');
  const payments_api = new squareConnect.PaymentsApi();
  const request_body = {
    source_id: request_params.nonce,
    amount_money: {
      amount: Math.round(request_params.amount * 100),
      currency: 'USD' as squareConnect.CurrencyType
    },
    tip_money: {
      amount: Math.round(request_params.tipAmount * 100),
      currency: 'USD' as squareConnect.CurrencyType
    },
    idempotency_key: idempotency_key
  };
  return payments_api.createPayment(request_body);
});

根據此處找到的 api 。 我應該得到一個錯誤類型數組的響應。 但是，當我像這樣在 api promise 上使用捕獲器時

return payments_api.createPayment(request_body).catch(err => console.log(err))

不是這樣的。 相反，它似乎是一個完整的錯誤響應

我可以在名為 text 的屬性下看到來自 api 的預期錯誤響應，但我不確定如何深入研究該數據

Answer 1

您需要處理錯誤，如文檔中所述：

為確保客戶端獲得有用的錯誤詳細信息，請通過拋出（或返回被拒絕的 Promise） functions.https.HttpsError實例從可調用對象中返回錯誤。

因此，在您的情況下，您應該執行以下操作（我假設createPayment()方法返回一個 Promise）：

export const processPayment = functions.https.onCall((data, context) => {
  //...
  return payments_api.createPayment(request_body)
  .catch(error => {
     throw new functions.https.HttpsError('<error-code>', '....');
  })
});

您將在此處找到有關如何處理客戶端錯誤的一些示例。

Answer 2

通過簡單地向下鑽取，我能夠得到預期的響應

return payments_api.createPayment(request_body).catch((err) => console.log(err.response.text));
