Firebase Cloud Functions - 抛出 Auth 错误

Question

是否可以从 HTTPs 可调用函数中抛出 Auth Error？

我的意思是，而不是这个

 if (err.code === "auth/email-already-exists") {
    throw new functions.https.HttpsError(
      "invalid-argument",
      "The email address is already in use by other account"
    );
  }

类似

exports.signUp = functions
  .region("us-central1")
  .runWith({ memory: "2GB", timeoutSeconds: 120 })
   .https.onCall(async (data, context) => {
      ...

      if (err.code === "auth/email-already-exists") {
        throw err;
      }

      ...
   }

Callable Functions 应该 return HttpsError which requires gRPC error codes 的一个实例，以便将错误的详细信息正确传输给调用客户端。如果您抛出不同的错误类型，客户端将只会看到带有代码和消息 "internal" 的 HttpsError - 出于安全考虑，不会将任何细节发送给客户端。

如果您想传递 Firebase 错误的错误代码，可以使用第三个参数。还可以考虑使用 "failed-precondition"（首选）或 "already-exists"（如果它是资源）。

if (err.code === "auth/email-already-exists") {
    throw new functions.https.HttpsError(
      "invalid-argument",
      "The email address is already in use by other account",
      { code: err.code }
    );
  }
