Getting a fatal error when autoloading a PHP class

问题

I am attempting to use Cartalyst, a comprehensive PHP Library for Stripe payments. Here is a link to their documentation: https://cartalyst.com/manual/stripe/1.0. Here is the code I am trying to get to work:

$stripe    = Stripe::make('your-stripe-api-key');
$customers = $stripe->customers()->all();

foreach ($customers['data'] as $customer) {
    var_dump($customer['email']);
}

When I run the code above (in my real code I have my api inserted), I receive the following error: Fatal error: Class 'Stripe' not found in on line 247. I have triple-checked everything I know to check and I cannot seem to figure out what the issue is. I have "autoloaded" the Stripe Cartalyst library and the Stripe library.

Also, here is my composer code that is generating the autoload files:

{
    "require": {
        "cartalyst/stripe": "~1.0",
        "stripe/stripe-php": "3.*"
    }
}

回答1:

It needs the namespace \Stripe, try:

 \Stripe\Stripe::setApiKey('your-stripe-api-key');
