我遇到的情况是,如果抛出任何异常,我需要调用相同的方法,以确保我不会复制任何代码。但是,它没有像我想的那样工作。这是相关的代码:
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;
}
正如您所看到的,我正在调用if
条件self::getFolderObject();
下的方法方法中的方法,以防止在方法开头的if
语句下重复代码。但是,如果我复制代码,它按预期工作。有没有解决方案来实现我的目标?

您错过了返回值并指定了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;
}
