Firebase云函数-抛出身份验证错误

是否可能从HTTPs可调用函数引发身份验证错误?

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

差不多

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;
      }

      ...
   }

HttpsError 这需要 gRPC error codes HttpsError 带着代码和信息 "internal" -为了安全起见,不会向客户发送任何详细信息。

如果要传递Firebase错误的错误代码,可以使用第三个参数。也考虑使用 "failed-precondition" (首选)或 "already-exists"

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 }
    );
  }
