我可以从同一个方法调用一个方法吗?

Can I call a method from the same method?

我处于这样一种情况,如果抛出任何异常我需要调用相同的方法以确保我没有重复任何代码。但是,它没有像我想的那样工作。这是相关代码:

public static function getFolderObject($folder_id)
    {
        $client = new Client('https://api.box.com/{version}/folders', [
            'version' => '2.0',
            'request.options' => [
                'headers' => [
                    'Authorization' => 'Bearer ' . self::getAccessToken(),
                ]
            ]
        ]);

        $request = $client->get($folder_id);

        try {
            $response = $request->send();
            $result = $response->json();

            $files = $result['item_collection']['entries'];
        } catch (BadResponseException $e) {
            $result = $e->getResponse()->getStatusCode();

            if ($result === 401) {
                self::regenerateAccessToken();
                self::getFolderObject();
            }
        }

        return count($files) ? $files : false;
    }

如您所见,我在 if 条件 self::getFolderObject(); 下从 method 方法调用方法,以防止在 if 语句下再次出现重复代码方法。但是,如果我复制代码,它会按预期工作。有什么解决方案可以实现我想要的吗?

您错过了 return 值并分配 folder_id:

public static function getFolderObject($folder_id)
    {
        $client = new Client('https://api.box.com/{version}/folders', [
            'version' => '2.0',
            'request.options' => [
                'headers' => [
                    'Authorization' => 'Bearer ' . self::getAccessToken(),
                ]
            ]
        ]);

        $request = $client->get($folder_id);

        try {
            $response = $request->send();
            $result = $response->json();

            $files = $result['item_collection']['entries'];
        } catch (BadResponseException $e) {
            $result = $e->getResponse()->getStatusCode();

            if ($result === 401) {
                self::regenerateAccessToken();
                return self::getFolderObject($folder_id);
            }
        }

        return count($files) ? $files : false;
    }
