我在集成了php图形sdk的laravel应用程序中使用了facebook graph api。我有一个统计页面，我在moris图表中显示每种类型的帖子数，排名前3的帖子以及一些见解指标，例如“ page_post_engagements”。 这是我的控制器：
public function stats($id,Facebook $fb)
{
$page = Page::find($id);
$page_fb_id = $page->fb_id;
$page_access_token = $page->access_token;
$oAuth2Client = $fb->getOAuth2Client();
$fb->setDefaultAccessToken($oAuth2Client->getLongLivedAccessToken($page_access_token)->getValue());
$nb_photos = '0';
$nb_videos = '0';
$nb_links = '0';
$nb_likes = '0';
$nb_comments = '0';
$nb_shares = '0';
$count_posts = '0';
$startDate = Carbon::now()->subDays('29');
$endDate = Carbon::now();
$numberOfDays = $endDate->diffInDays($startDate);
$classement = array();
$posts = $fb->get('/'.$page_fb_id.'/posts?fields=type&since='.Carbon::parse($startDate).'&until='.Carbon::parse($endDate))->getGraphEdge();
if(empty($posts))
{
$classement = ['total'=>0,'likes'=>0,'comments'=>0,'shares'=>0];
}
else
{
foreach ($posts as $key => $post)
{
if($post['type'] == 'photo')
{
$nb_photos++;
}
else if($post['type'] == 'video')
{
$nb_videos++;
}
else if($post['type'] == 'link')
{
$nb_links++;
}
$count_posts++;
$impress = $fb->get('/'.$post['id'].'/insights?metric=post_impressions_unique')->getGraphEdge();
$engage = $fb->get('/'.$post['id'].'/insights?metric=post_engaged_users')->getGraphEdge();
$classement[] = ['total'=>($engage[0]['values'][0]['value']/$impress[0]['values'][0]['value'])*100,'id'=>$post['id'],'impressions'=>$impress[0]['values'][0]['value'],'engage'=>$engage[0]['values'][0]['value']];
}
if(is_array($classement))
{
asort($classement);
$tops = array_slice($classement, -3, 3);
$start_elem = array_slice($tops, 0, 1);
$mid_elem = array_slice($tops, 1, 1);
$end_elem = end($tops);
}
if($end_elem['id'])
{

有没有一种方法可以优化我的代码，以便获得更好的响应时间，特别是避免在10000毫秒异常后连接超时？
答案 0 :(得分：0)
我假设要获取API数据并对其进行解析...花费的时间超过10秒？
您需要做两件事来改善您的系统：1）使用缓存2）使用队列。
缓存！ （将API /解析的结果保存15分钟左右）
排队！ （API解析是在服务器后台完成的）
您的系统工作流程将是：
用户点击了/stats
是否有缓存版本？用它。响应时间大约只有500毫秒。
否/缓存已过期？触发排队作业以获取新的API数据。
显示用户“正在刷新数据！”并显示最新的缓存。
