fix: Test transaction may also return 401 when queried in the production environment

@BB-5XGames , I think the func (c *APIClient) Verify(ctx context.Context, transactionId string) (*TransactionInfoResponse, error) could meet your requirement. Please correct me if anything wrong.

I tried using this interface directly, but it couldn't query the sandbox again in the case of a 401
The error is displayed as:
appstore api: https:api.storekit.itunes.apple.com/inApps/v1/transactions/xxxxxxxxxxxxxx return status code 401

First of all. Per doc, the 401 Unauthorized

The JSON Web Token (JWT) in the authorization header is invalid

It means the jws token you provided is not valid. I think the jws token of your sandbox environment and production environment are different, am I right?

If so, I think the better solution to solve it is that try the sandbox environment validation when the error is not nil . The codes like below.

func (c *APIClient) Verify(ctx context.Context, transactionId string) (*TransactionInfoResponse, error) {
	result, err := c.productionCli.GetTransactionInfo(ctx, transactionId)
	if err != nil  {
		result, err = c.sandboxCli.GetTransactionInfo(ctx, transactionId)
	}
	return result, err
}

Please correct me if anything missing. @BB-5XGames

I think the JWT used in the test and production environments should be the same, both generated by the code here, right?

authToken, err := a.Token.GenerateIfExpired()

This is indeed my temporary solution for now

func (c *APIClient) Verify(ctx context.Context, transactionId string) (*TransactionInfoResponse, error) {
	result, err := c.productionCli.GetTransactionInfo(ctx, transactionId)
	if err != nil  {
		result, err = c.sandboxCli.GetTransactionInfo(ctx, transactionId)
	}
	return result, err
}

Yes, the jwt token is same both in test and production environment. However, please make sure the those values of Token is correct

	KeyID         string       // Your private key ID from App Store Connect (Ex: 2X9R4HXF34)
	BundleID      string       // Your app’s bundle ID
	Issuer        string       // Your issuer ID from the Keys page in App Store Connect (Ex: "57246542-96fe-1a63-e053-0824d011072a")

following this doc https://developer.apple.com/documentation/appstoreserverapi/creating-api-keys-to-authorize-api-requests.

Since the return code is 401, it means some of above parameters are not correct. You may double check them. @BB-5XGames
