-- The plugin must inherit the `Base` class
-- The plugin must implement the `filter` function
-- `filter` function parameters can only contain `Request` and `Response` classes as parameters
-- Request parameter can get and set request information
-- Response parameter can set response information
-- `self.config` can get plug-in configuration information
+- Plugins must inherit the `PluginBase` class and implement all functions.
+  - `name` function: used to set the registered plugin name.
+  - `config` function: used to parse plugin configuration.
+  - `filter` function: used to filter requests.
+    - `conf` parameter: plugin configuration after parsing.
+    - `request` parameter: Request object, which can be used to get and set request information.
+    - `response` parameter: Response object, which can be used to set response information.
