一，修改composer.json
"autoload": {"psr-4": {"App\\": "app/"},"files": ["app/Functions.php"]},在files数组中增加我们的函数文件
二，源代码
app/Functions.php
<?phpuse Hyperf\Context\ApplicationContext;
use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\HttpServer\Contract\ResponseInterface;if (! function_exists('container')) {/*** 获取容器对象** @param string $id* @return mixed|\Psr\Container\ContainerInterface* @throws \Psr\Container\ContainerExceptionInterface* @throws \Psr\Container\NotFoundExceptionInterface*/function container(string $id = ''): mixed{$container = ApplicationContext::getContainer();if ($id) return $container->get($id);return $container;}
}if (! function_exists('request')) {/*** request 实例** @return RequestInterface|mixed* @throws \Psr\Container\ContainerExceptionInterface* @throws \Psr\Container\NotFoundExceptionInterface*/function request(): mixed{return container()->get(RequestInterface::class);}
}if (! function_exists('response')) {/*** response 实例** @return ResponseInterface|mixed* @throws \Psr\Container\ContainerExceptionInterface* @throws \Psr\Container\NotFoundExceptionInterface*/function response(): mixed{return container()->get(ResponseInterface::class);}
}if (! function_exists('get_client_ip')) {/*** 获取客户端 ip** @return mixed|string* @throws \Psr\Container\ContainerExceptionInterface* @throws \Psr\Container\NotFoundExceptionInterface*/function get_client_ip(): string{$request = request();return $request->getHeaderLine('X-Forwarded-For')?: $request->getHeaderLine('X-Real-IP')?: ($request->getServerParams()['remote_addr'] ?? '')?: '127.0.0.1';}
}调用函数
controller/ImageController.php
public function imagedetail(RequestInterface $request, ResponseInterface $response) {$ip = get_client_ip();$data = ['ip' => $ip];return $response->json($data);}三，测试效果:
