Laravel AWS S3存储映像缓存 [英] Laravel AWS S3 Storage image cache
问题描述
我有一个基于Laravel的Web和移动应用程序，用于在AWS S3上存储图像，并且我想增加缓存支持，因为即使是少数应用程序用户也会在AWS S3上生成数百甚至是大量的GET请求。
I have Laravel based web and mobile application that stores images on AWS S3 and I want to add cache support because even small number of app users produce hundreds and sometimes thouthands of GET requests on AWS S3.
要从移动应用程序中获取图像，我使用GET请求，该请求由此类代码处理
To get image from mobile app I use GET request that is being handled by code like this
public function showImage(....) {
...
return Storage::disk('s3')->response("images/".$image->filename);
}
在下一张图片上，您可以看到我收到的响应标头。缓存控件显示无缓存，因此我认为移动应用程序不会缓存该图像。
On the next image you can see response headers that I receive. Cache-Control shows no-cache so I assume that mobile app won't cache this image.
- 如何为该请求添加缓存支持？我应该这样做吗？
- 我知道 Laravel Documentaion建议用于文件存储的缓存-我应该为S3实现它吗？它可以帮助减少来自AWS S3的GET请求读取文件的数量吗？在哪里可以找到有关它的更多信息。
- How can I add cache support for this request? Should I do it?
- I know that Laravel Documentaion suggests caching for Filestorage - should I implement it for S3? Can it help to decrease GET requests count of read files from AWS S3? Where can I find more info about it.
推荐答案
您可以使用CloudFlare这样的CDN服务并设置一个缓存标头，以使CloudFlare在一定时间内保留缓存。
You could use a CDN service like CloudFlare and set a cache header to let CloudFlare keep the cache for a certain amount of time.
$s3->putObject(file_get_contents($path), $bucket, $url, S3::ACL_PUBLIC_READ, array(), array('Cache-Control' => 'max-age=31536000, public'));
这样，文件将由CloudFlare提取一次，存储在其服务器中，并提供给用户，而无需从S3请求图像
This way, files would be fetched once by CloudFlare, stored at their servers, and served to users without requesting images from S3 for every single request.
