+### `Http Client Response`
+
+自 Laravel 12.43 版本起，`Illuminate\Http\Client\Response` 类支持宏，具体查看这个 [PR](https://github.com/laravel/framework/pull/58115)。
+
+```php
+use Illuminate\Http\Client\Response;
+
+Response::macro(
+    'movieFields',
+    fn () => $this->collect()->only('title', 'year', 'runtime', 'director', 'plot')
+);
+
+$response = Http::get(...);
+$response->movieFields();
+```
+
 ### `Validation`
 
 注意 `Validator` 使用是 **`extend`** 方法来自定义宏，并不是 `micro` 方法。
