请在主题函数中放置以下代码。php文件（&P）；让我知道情况：）

add_action(\'wp\', function(){
    list($uri, $qs) = explode(\'?\', $_SERVER[\'REQUEST_URI\']);
    if ( $uri == "/arbitrary/path" ) /* Change this to path that you want to match*/
    {
        locate_template( "template-full-width.php" , true, false ); /* Don\'t forget to replace template name with actual template which you want to load */
        die(); /* So that WordPress does not load its template as per template hierarchy. */
    }         
});
