WordPress REST API REGISTER_REST_ROUTE出现500错误

时间：2020-04-06 作者：sialfa

我想创建一个类来注册我的自定义主题rest路由。在我编写了这段代码之后，我注意到RESTAPI将给出500个错误，而axios无法获取数据。我想通过使用vue创建一个单页wordpress网站来获取页面内容，但目前我需要解决这个问题。有人能帮我吗？我的代码正确吗？

class Uheme_Rest_Routes {

  public static function init()
  {
    add_action( \'rest_api_init\', array( __CLASS__, \'uheme_routes\') );
  }

  public function uheme_routes()
  {
    register_rest_route(
      \'uheme/v1\',
      \'/menu\',
      array(
        \'method\' => \'GET\',
        \'callback\' => array($this, \'_rest_menu\')
      )
    );

  }

  public function _rest_menu()
  {
    return wp_get_nav_menu_items(\'menu\');
  }

}
Uheme_Rest_Routes::init();

To other readers, another issue was the OP used the wrong route.

So make sure to make the API request to the correct route, which is a combination of the first two parameters for register_rest_route() (namespace + route base). So with register_rest_route( \'uheme/v1\', \'/menu\' ), the route is uheme/v1/menu. Additionally:

With permalinks enabled, you can get a pretty endpoint URL (for the above route) like https://example.com/wp-json/uheme/v1/menu
But regardless permalinks enabled or disabled, the endpoint is also accessible at index.php?rest_route=<route> as in https://example.com/index.php?rest_route=/uheme/v1/menu

And to OP, if a callable/callback is in the form of array( __CLASS__, \'method_name\' ) (or maybe \'My_Class::method_name\'), then you need to define the class method as static (e.g. public static function method_name()) to prevent PHP errors. :)

And note that you also made a mistake with that \'method\' => \'GET\' which should be \'methods\' => \'GET\' — note the plural "methods". For GET (request) method, that method would work because GET is the default method, but if you were only allowing POST method and you used \'method\' => \'POST\', then that wouldn\'t work — POST would never be allowed! So once again, the correct array key is methods.

Original answer

Your original class (without extending WP_REST_Routes) worked for me, after I changed the $this to __CLASS__:

\'callback\' => array($this, \'_rest_menu\') // I changed this
\'callback\' => array(__CLASS__, \'_rest_menu\') // to this

Without that change, I got this error:

{"code":"rest_invalid_handler","message":"The handler for the route is invalid","data":{"status":500}}

So make sure you provide a valid callable/callback as the route handler. Or that be aware that in your utheme_routes() method, the $this is not available because you didn\'t do something like $instance = new Uheme_Rest_Routes; $instance->init();.

Update: You can also try changing the \'method\' => \'GET\' to \'methods\' => \'GET\'. And be sure the route is /wp-json/uheme/v1/menu.
