我在 CakePHP 中使用 session 变量来存储我的相关用户 Twitter 和 Facebook 数据,当用户登录时,如果他链接了他的 Twitter 和 FB 帐户,则此信息将保存在我自己的用户数据旁边的 session 变量中。
我有一个屏幕,用户可以在其中链接和取消链接所述社交网络数据,问题如下:
假设我连接了两个网络,我决定与 Facebook 断开连接,Facebook 的 session 变量被删除。现在我想重新连接到 Facebook,我点击了连接按钮,Facebook 数据被保存,但由于某种原因它删除了 Twitter 变量。
我的流程的工作方式如下:
1) 用户点击连接按钮。
2) 用户被定向到社交网络身份验证。
3) 用户被定向到一个函数,该函数获取所需的数据,将其保存在一个名为 NetworkData 的 session 变量中,然后被定向回他单击按钮的页面。
4)提取NetworkData,设置为 session 中对应的社交网络(Facebook或Twitter),并从 session 中删除。
代码如下:
这是用户登录 Twitter 或 FB 后被引导的功能:
function retrieve_network($page) {
$networkData = null;
$this->autoRender = false;
$this->layout = 'ajax';
if(isset($_GET['oauth_token'])) {
$token = $this->TwitterHelper->setOAuthToken($_GET['oauth_token']);
$userinfo = $this->TwitterHelper->getTwitterUserInfo();
$networkData = array(
'TwitterData' => array(
'username' => $userinfo['username'],
'name' => $userinfo['name'],
'token' => $token->oauth_token,
'token_secret' => $token->oauth_token_secret
)
);
} else if (isset($_GET['code'])) {
$token = $this->FacebookHelper->facebook->getAccessToken();
$userinfo = $this->FacebookHelper->getUserInfo();
$networkData = array(
'FacebookData' => array(
'username' => $userinfo['username'],
'name' => $userinfo['name'],
'email' => $userinfo['email'],
'token' => $token,
'link' => $userinfo['link'],
)
);
}
$this->Session->write('NetworkData', $networkData);
if($page == 'settings') {
$this->redirect(array('controller' => 'fonykers', 'action' => 'settings/networks'));
}
}
这是检索网络数据中的内容并将其设置为 session 的函数:
function settings($tab) {
$this->layout = 'frontend';
$this->Fonyker->recursive = -1;
$this->TwitterData->recursive = -1;
$this->FacebookData->recursive = -1;
if(!$this->checkSessionCookie()) {
$this->redirect(array('controller' => 'pages', 'action' => 'home'));
}
$fields = array(
'Fonyker.id',
'Fonyker.username',
'Fonyker.name',
'Fonyker.email',
'Fonyker.gender',
'Fonyker.birthdate',
'Fonyker.image_url'
);
$fonyker = $this->Fonyker->find('first', array(
'conditions' => array(
'Fonyker.fonykid' => $this->Session->read('Fonyker.Fonyker.fonykid')
),
'fields' => $fields
));
$this->Fonyker->set($fonyker);
$this->data = $fonyker;
if($this->Session->read('NetworkData')) {
$networkData = $this->Session->read('NetworkData');
$this->Session->delete('NetworkData');
if($networkData['TwitterData']) {
$networkData['TwitterData']['fonyker_id'] = $fonyker['Fonyker']['id'];
if($this->TwitterData->save($networkData)) {
$this->Session->write('TwitterData', $networkData['TwitterData']);
}
} else if($networkData['FacebookData']) {
$networkData['FacebookData']['fonyker_id'] = $fonyker['Fonyker']['id'];
if($this->FacebookData->save($networkData)) {
$this->Session->write('FacebookData', $networkData['FacebookData']);
}
}
}
pr($this->Session->read());
if(!$this->Session->read('TwitterData')) {
$this->TwitterHelper->setTwitterObj();
$this->set('twitterUrl', $this->TwitterHelper->twitterObj->getAuthorizeUrl(null, array('oauth_callback' => 'http://127.0.0.1/fonykweb/pages/retrieve_network/settings')));
} else {
$this->set('twitterUrl', '#');
}
if(!$this->Session->read('FacebookData')) {
$this->set('facebookUrl', $this->FacebookHelper->facebook->getLoginUrl(array('redirect_uri' => 'http://localhost/fonykweb/pages/retrieve_network/settings','scope' => 'email,user_birthday,publish_stream,offline_access')));
} else {
$this->set('facebookUrl', '#');
}
$this->set('tab', $tab);
}
如果用户愿意,这是删除网络的功能:
function remove_network($network) {
$this->autoRender = false;
$this->Fonyker->recursive = -1;
$this->TwitterData->recursive = -1;
$this->FacebookData->recursive = -1;
$response = null;
if($network == 'twitter') {
$twitterData = $this->TwitterData->find('first', array(
'conditions' => array(
'TwitterData.fonyker_id' => $this->Session->read('TwitterData.fonyker_id')
)
));
if($this->TwitterData->delete($twitterData['TwitterData']['id'], false)) {
$this->TwitterHelper->setTwitterObj();
$twitterUrl = $this->TwitterHelper->twitterObj->getAuthorizeUrl(null, array('oauth_callback' => 'http://127.0.0.1/fonykweb/pages/retrieve_network/settings'));
$this->Session->delete('TwitterData');
$response = json_encode(array('ok' => true, 'url' => $twitterUrl));
} else {
$response = json_encode(array('ok' => false));
}
}
if($network == 'facebook') {
$facebookData = $this->FacebookData->find('first', array(
'conditions' => array(
'FacebookData.fonyker_id' => $this->Session->read('FacebookData.fonyker_id')
)
));
if($this->FacebookData->delete($facebookData['FacebookData']['id'], false)) {
$facebookUrl = $this->FacebookHelper->facebook->getLoginUrl(array('redirect_uri' => 'http://localhost/fonykweb/pages/retrieve_network/settings','scope' => 'email,user_birthday,publish_stream,offline_access'));
$this->Session->delete('FacebookData');
$response = json_encode(array('ok' => true, 'url' => $facebookUrl));
} else {
$response = json_encode(array('ok' => false));
}
}
echo $response;
}

抱歉,帖子太长了。
最佳答案
在您的retrieve_network 操作中,我假设您在用户重新连接到特定服务时调用该操作,您正在覆盖 NetworkData session 变量
如果您发现 1 个特定服务已连接到:
if(isset($_GET['oauth_token'])) {...}
或者
if(isset($_GET['code'])) {...}
您将 $networkData 设置为返回的服务对象,然后通过以下方式覆盖整个 session :
$this->Session->write('NetworkData', $networkData);
按照您的代码,我将始终检查现有服务当前是否处于 session 中,如果是,则不要覆盖整个 session ,只需将特定数据添加到现有 NetworkData session 数组中:
if($this->Session->read('NetworkData.TwitterData')){
$facebookData = array(
'username' => $userinfo['username'],
'name' => $userinfo['name'],
'email' => $userinfo['email'],
'token' => $token,
'link' => $userinfo['link'],
);
$this->Session->write('NetworkData.FacebookData', $facebookData);
}
注意:这只是一个示例,展示了如何实现这一目标。对于这种特殊情况,我会用更好的逻辑重构该方法,也许将 TwitterData 和 FacebookData 存储在它们自己的单独数组中,而不是更大更复杂的 NetworkData 数组。此外,您可以通过 $this->params['url']['paramname'] 访问 $_GET 参数以维护 cakePHP 约定。
