使用CURL_EXEC时“无效的API请求”

Question

i have the following php code that calls an API:

$forcetest = 1;

$url = "https://www.website.com/api/pointTotal.php?userId=" . $userId;
if ($forcetest || (isset($_SERVER['ON_TEST_SERVER']) && ($_SERVER['ON_TEST_SERVER']))){
    $url = "https://wwwtest.website.com/api/pointTotal.php?userId=" . $userId;
}

$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_URL => $url
));

curl_setopt($curl, CURLOPT_HTTPHEADER, array(
    'sharedSecret: abc123',
));

//curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); //tested to see if this would work, didn't seem to matter

// Only do this if on dev/test
if ($forcetest || (isset($_SERVER['ON_TEST_SERVER']) && ($_SERVER['ON_TEST_SERVER']))) {
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
}

$response = curl_exec($curl);
print($response);
if(!$response){
    die('Error: "' . curl_error($curl) . '" - Code: ' . curl_errno($curl));
}

my problem is when going to production (i.e. $forcetest = 0;) it works just fine, calling the prod api and using the prod database. if i switch it, and it goes to the wwwtest subdomain to call the test api, i get the error returned {"success":false,"errors":["Invalid API request"]}

"invalid api request" isn't something in the api's code, so it seems to me that its something curl_exec is doing/erroring on but i can't figure out what. if i go to the api's directly, they both return the correct information in my browser, so i know it's up and working. is it maybe a cert issue or some sort of xss setting on that subdomain/server that's causing it to error? i'm kind of at a loss.

Thanks in advance.

edit: CLI curl command and header output:

also added this to the php code making the call

curl_getinfo($curl, CURLINFO_HEADER_OUT) and it prints out a 404 which is what seems to be the problem but going to the url it's curl'ing immediatley returns the correct result so i'm not sure what's causing the 404

Answer 1

Sorry, just now saw this question was still open. The problem turned out to be bad internal DNS. the code and the curl we're all correct, i had to rely on the sys admin's to resolve it.
