使用 PHP 获取 vimeo 缩略图的最快方法是什么
我使用以下 PHP 代码根据 vimeo API
private function curl_get($url)
{
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_TIMEOUT, 30);
$return = curl_exec($curl);
curl_close($curl);
return $return;
}
在对页面进行分析后，我注意到curl_exec大约需要220毫秒，考虑到我只想要视频的缩略图，我发现这个时间很多。
您知道获取缩略图的更快方法吗？
I am using the following code, in PHP, to get the thumbnail (from the JSON) of a vimeo video according to the vimeo API
private function curl_get($url)
{
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_TIMEOUT, 30);
$return = curl_exec($curl);
curl_close($curl);
return $return;
}
After profiling the page I noticed that it takes to curl_exec about 220 milliseconds, which I find a lot considering that I only want the thumbnail of the video.
Do you know a faster way to get the thumbnail?

这可能是网络开销（DNS查找-连接-传输-获取传输的数据）。可能无法进一步加快速度。
确保您在本地缓存结果，这样就不必每次都重新获取它们。
It's probably the network overhead (DNS lookup - connect - transfer - fetching the transferred data). It may not be possible to speed this up any further.
Make sure you are caching the results locally, so they don't have to be fetched anew every time.
