Handlers / Middleware

If you need to modify the underlying Guzzle request/response right before it is sent, you can use handlers. This is an incredibly useful feature that Guzzle provides to view/modify the request before it is sent.

To add a handler or middleware, simply use the addHandler method in your plugin or boot method on your connector/request.

Example

use Psr\Http\Message\RequestInterface;

class CreateForgeServerRequest extends SaloonRequest
{
    //...

    public function boot(SaloonRequest $request): void
    {
        $this->addHandler('customHeaderHandler', function (callable $handler) {
            return function (RequestInterface $request, array $options) use ($handler) {
                $request->withHeader('X-Custom-Header', 'Hello');
                
                return $handler($request, $options);             
            };
        });
    }
}

Saloon will not know about any extra headers, configuration or data you add inside of handlers.
