Question

我正在实施一些来自Instagram的照片，用于我的页脚作为我的laravel项目中的装饰。但是当我刷新页面时，它会一遍又一遍地进行api调用。我正在考虑在会话中缓存或存储呼叫，因此我不必总是发送API请求...那么如何缓存此api请求？

PHP：

<?php
$clientid = "XXXXXXXXXXXXXXXXXXXXXXXX";
$url = "https://api.instagram.com/v1/tags/kittens/media/recent?client_id=".$clientid;

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);

$results = json_decode(curl_exec($curl));
?>

HTML：

<footer>
<?php
    echo "<ul class='inline-list'>";    
    foreach ($results->data as $result) {
        echo "<li><img src='".$result->images->thumbnail->url."'></li>";
    }
    echo "</ul>";
?>
</footer>

要缓存请求，您可以将其写入文件并检查修改日期或使用某种缓存库。

例如http://www.phpfastcache.com/

// In your config file
include("phpfastcache/phpfastcache.php");
phpFastCache::setup("storage","auto");

// phpFastCache support "apc", "memcache", "memcached", "wincache" ,"files", "sqlite" and "xcache"
// You don't need to change your code when you change your caching system. Or simple keep it auto
$cache = phpFastCache();

// In your Class, Functions, PHP Pages
// try to get from Cache first. product_page = YOUR Identity Keyword
$results = $cache->get("cache_instagram");

if($results == null) {
    $clientid = "XXXXXXXXXXXXXXXXXXXXXXXX";
    $url = "https://api.instagram.com/v1/tags/kittens/media/recent?client_id=".$clientid;

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);

    $results = json_decode(curl_exec($curl));
    // set products in to cache in 600 seconds = 10 minutes
    $cache->set("cache_instagram", $results,600);
}

// Output Your Contents $products HERE
// Re-written first example from page for purpouse of your script.

对于Laravel内置缓存

// http://laravel.com/docs/4.2/cache

if (Cache::has('cache_instagram')) {
    $results = Cache::get('cache_instagram');

} else {
    $clientid = "XXXXXXXXXXXXXXXXXXXXXXXX";
    $url = "https://api.instagram.com/v1/tags/kittens/media/recent?client_id=".$clientid;

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);

    $results = curl_exec($curl);

    Cache::put('cache_instagram', $results, 60); // 1 hour

}

$results = json_decode($results);
