他是我当前的自定义API：

add_action( \'rest_api_init\', function () {
  register_rest_route(\'my-project/v1/form\', \'/get\', array(
    \'methods\' => WP_REST_Server::READABLE,
    \'callback\' => \'get_form\'
  ));
});


add_action( \'rest_api_init\', function () {
  register_rest_route(\'my-project/v1/form\', \'/post\', array(
    \'methods\' => \'POST\',
    \'callback\' => \'post_form\'
  ));
});

这里有一些我想写的东西，但我不确定是否可能。我可以肯定的是，这个语法

add_action( \'rest_api_init\', function () {
  register_rest_route(\'my-project/v1/\', \'/form\',
array(
    \'methods\' => \'GET\',
    \'callback\' => \'GET_form\',
  ), array(
    \'methods\' => \'POST\',
    \'callback\' => \'post_form\',
  ), );
});

add_action( \'rest_api_init\', function () {

    register_rest_route(\'my-project/v1/\', \'/form\', 
        array(
            array(\'methods\' => \'GET\',
                 \'callback\' => \'GET_form\',
            ), 
            array(\'methods\' => \'POST\',
                 \'callback\' => \'post_form\'
            )
        ) 
    );
});
