WP_Http::_dispatch_request( string $url, array $args )

Dispatches a HTTP request to a supporting transport.


Tests each transport in order to find a transport which matches the request arguments. Also caches the transport instance to be used later.

The order for requests is cURL, and then PHP Streams.



(string) (Required) URL to Request


(array) (Required) Request arguments


(array|WP_Error) Array containing 'headers', 'body', 'response', 'cookies', 'filename'. A WP_Error instance upon error
