如何缓存Twitter API的结果？ [英] how to cache the twitter api result?

问题描述

我想缓存twitter api结果的结果并将其显示给用户。

I would like to cache the result of the twitter api result and display them to users..

缓存结果的最佳方法是什么？

What's the best method to cache the result?

我正在考虑根据时间限制将结果写入文件中。是否可以使用其他方法？

I'm thinking a writing the result into a file based on a time limit.. Is that ok or any other method should be used?

最重要的是，理想的缓存时间是多少？我想显示来自Twitter的最新内容，但是Twitter api有请求限制。.
而且我的站点每天有稳定的访问者。

And most importantly what would be the ideal cache time ? I would like to display the latest content from the twitter but the twitter api has the request limits.. And my site has solid visitors/day..

推荐答案

最干净的方法是使用 APC （备用PHP缓存）（如果已安装）。它具有内置的生存时间功能：

The cleanest way to do this would be to use APC (Alternative PHP Cache) if it installed. This has a built in "time to live" functionality:

if (apc_exists('twitter_result')) {
    $twitter_result = apc_fetch('twitter_result');
} else {
    $twitter_result = file_get_contents('http://twitter.com/...'); // or whatever your API call is
    apc_store('twitter_result', $twitter_result, 10 * 60); // store for 10 mins
}

10分钟的数据超时将是我的选择。这取决于Feed的更新频率...

A 10 minute timeout on the data would be my choice. This would vary depending on how frequently the feed is updated...

编辑没有安装APC，您可以使用一个非常简单的文件执行此操作：

Edit If you don't have APC installed, you could do this using a very simple file:

if (file_exists('twitter_result.data')) {
    $data = unserialize(file_get_contents('twitter_result.data'));
    if ($data['timestamp'] > time() - 10 * 60) {
        $twitter_result = $data['twitter_result'];
    }
}

if (!$twitter_result) { // cache doesn't exist or is older than 10 mins
    $twitter_result = file_get_contents('http://twitter.com/...'); // or whatever your API call is

    $data = array ('twitter_result' => $twitter_result, 'timestamp' => time());
    file_put_contents('twitter_result.data', serialize($data));
}
