来自外部 API 调用的 Firebase 函数 return 错误文本
Firebase functions return error text from external API call
我正在使用 Firebase 函数通过 Square 处理信用卡。我的功能非常适合成功的卡交易。但是，对于诸如被拒绝或不正确的 cvv 之类的卡错误，我想将该错误上下文发送给用户。我当前的代码发生了什么，我只是从云函数中收到错误 500。当我查看函数日志时，它有一个未处理的错误 { Error: Bad Request... 我可以在日志中看到所需的文本，但这不会传递到前端。这是我当前的代码。
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);
});
根据api发现here。我应该得到错误类型数组的响应。但是，当我像这样在 api promise 上使用 catch
return payments_api.createPayment(request_body).catch(err => console.log(err))
不是那样的。相反，它似乎是一个完整的错误响应

我可以在 属性 调用的文本下看到来自 api 的预期错误响应，但我不确定如何向下钻取到该数据
您需要按照 documentation:
中的说明处理错误
To ensure the client gets useful error details, return errors from a
callable by throwing (or returning a Promise rejected with) an
instance of functions.https.HttpsError.
因此，在您的情况下，您应该执行以下操作（我假设 createPayment() 方法 returns 是一个 Promise）：
export const processPayment = functions.https.onCall((data, context) => {
//...
return payments_api.createPayment(request_body)
.catch(error => {
throw new functions.https.HttpsError('<error-code>', '....');
})
});
可能的错误代码列表是 here。
您会发现here，一些关于如何在客户端处理错误的示例。
通过简单地向下钻取
，我能够得到预期的响应
return payments_api.createPayment(request_body).catch((err) => console.log(err.response.text));
