So I was writing a simple PHP script to check a database to see whether a license key was contained within it. `

if (!isset($_POST['License'])) {
    exit('No License Found');

$authtoken = $_POST['License'];
$query = "SELECT * FROM nexus_licensekeys WHERE lkey_key='$authtoken'";

if($result = $conn->query($query)){
    if($row = $result->fetch_assoc()){
        echo "AUTHORIZED";
        echo "NOT AUTHORIZED";
    echo "FAILED";

When I send a post request with a license key contained within the database, "No License Found" is returned. I've tried sending a post request in many different way but I can't figure out why it isn't receiving the post data.

2020欧洲杯时间表This is how I am sending the post data:

net::requests m_request(L"webp", false);
std::wstring answer = m_request.Post(false, URL, "License=%s", Licence.c_str());

if (answer == L"AUTHORIZED") { return true; }
else if (answer == L"NOT AUTHORIZED") { return false; }
else if (answer == L"FAILED") { return false; }
else if (answer == L"No License Found") { return false; }
else { return false; }

  • Sorry, I'm not familiar with this syntax. What language is that? – Vladimir Mar 27 at 5:01
  • c++, but it isn't a client side issue. Even when i use a program like postman, i still get the same result. – Gabe M Mar 27 at 5:17
  • Can you add what you get in PHP with var_dump($_POST);? If there's nothing, the C++ doesn't generate a valid POST request. You might want to add the SO tag 'c++' to get help there. ALSO IN ANY CASE your PHP code is vulnerable to SQL injection by POST data! You should look into prepared statements to avoid that. – Jonas Eberle Mar 27 at 8:05
