The *wp_http_accept_encoding* filter works with the HTTP API methods to set allowed compression encoding when making external HTTP calls.
When the 'wp_http_accept_encoding' filter is called, it is passed three parameters: an array of encoding types, URL of target site, array of all HTTP arguments.
add_filter( 'wp_http_accept_encoding', 'filter_function_name', 10, 3 );
function filter_function_name( $type, $url, $args ) {
// Alter available encoding types
return $type;
}
Where 'filter_function_name' is the function WordPress should call when filter is run. Note that the filter function must return an value after it is finished processing or the HTTP call will fail.
filter_function_name should be unique function name. It cannot match any other function name already declared.
add_filter( 'wp_http_accept_encoding', 'filter_function_name', 10, 3 );
function filter_function_name( $type, $url, $args ) {
// Alter available encoding types
return $type;
}
add_action( 'init', 'get_google_home' );
function get_google_home() {
$google = wp_remote_get( "http://google.com" );
}
