is_object() authorize.net 之前不可见的 \ 字符

Question

I am using the sample code from the PHP SDK and the package throws an error of

Call to undefined function net\\authorize\\api\\contract\\v1\\ is_object().

It looks like its coming from this call:

$response = $controller->executeWithApiResponse(\net\authorize\api\constants\ANetEnvironment::SANDBOX);

That in turns calls this:

vendor/authorizenet/authorizenet/lib/net/authorize/api/contract/v1/CreateTransactionResponse.php:72

I saw an issue open on their Github page that's been around for a bit now. Anyone else seen this? How can you fix this if its coming from the actual vendors code?

Answer 1

Using their API directly, not through the SDK, the response had three invisible characters at the start. Since it is a JSON response, I created a loop that would remove the starting character until a opening bracket is encountered. You may be able to fix their SDK with something similar.

    while ('{' !== $cleaned_response[0]) {
        $cleaned_response = substr($cleaned_response, 1);
    }
