我有一个使用 API 将 twitter 链接到它的应用程序,在此操作中,我创建了一个请求密钥,在此处完成:
public function createRequestKey()
{
$this->setScenario(self::SCENARIO_DEFAULT);
if (!$this->validate())
return false;
$cache = \Yii::app()->cache;
$key = __CLASS__ . '_' . $this->user->id . '_' . time() . '_' . rand(0, 100);
$key = sha1($key);
$data = array(
'userId' => $this->user->id,
);
$cache->set($key, $data, 60 * 30);
$this->requestKey = $key;
return true;
}
调用此方法的操作是这样的:
public function actionTwitterLinkUrl()
{
if (!$this->checkOAuthRequest())
return;
$request = \Yii::app()->getRequest();
$response = \Yii::app()->response->setContentTypeToJSON();
$user = $this->getUserFromHeader();
$this->matchUserToLastValidatedToken($user);
$linker = new \Sakanade\Operations\APITwitterLinker($user);
if ($linker->createRequestKey()) {
$params = $this->createQueryStringParams($linker->requestKey);
$response->set('type',UserProfile::profileTypeToString(UserProfile::PROFILETYPE_TWITTER))
->set('url', $request->getBaseUrl(true) . '/users/' . urlencode($user->id)
. '/profiles/twitter/link?' . http_build_query($params));
} else {
$response->setStatusCode(\Harusame\Components\HttpResponse::STATUS_BAD_REQUEST)
->addMessage(\Sakanade\Models\Model::flattenErrorMessages($linker));
}
$response->render();
}
但是在调用下一个操作时,如果我使用 $cache->get($key) 访问缓存,它会返回 false,即使它将缓存的存储时间设置为大约 1800 秒。
public function actionTwitterRunLink()
{
$request = \Yii::app()->request;
$requestKey = $request->getQuery('key');
if (!$this->checkOAuthRequest())
return;
$user = $this->getUserFromHeader();
$this->matchUserToLastValidatedToken($user);
$authUrl = $this->getAuthorizationUrl($user);
$response = \Yii::app()->response->setContentTypeToJSON();
$cache = \Yii::app()->cache;
$response->set('key', $cache->get($requestKey))
->set('key2', $requestKey);
$response->render();
}
从缓存中显示呈现的键后,它会返回 false,但是如果我尝试从上一个操作中获取它,则会有一个返回值。为什么在调用另一个操作时会清除缓存?任何帮助将不胜感激!
