Method of using PHP and Qiniu cloud storage interface to realize image content distribution and CDN acceleration

In modern Internet applications, image content distribution and acceleration are very critical and can effectively improve user experience. experience and website performance. Qiniu Cloud Storage, as the leading cloud storage service provider in China, provides us with a rich API interface, allowing us to easily achieve image content distribution and CDN acceleration through PHP code. This article will introduce how to combine PHP and Qiniu cloud storage interface to achieve image content distribution and CDN acceleration.

First, we need to create a storage space on Qiniu Cloud Storage and obtain the corresponding Access Key and Secret Key for API authentication.

Next, we need to use the third-party library qiniu/php-sdk to easily use the API interface of Qiniu Cloud Storage. You can install this library through Composer and run the following command:

composer require qiniu/php-sdk

After the installation is complete, we can start writing PHP code to achieve image content distribution and CDN acceleration.

First, we need to introduce the qiniu/php-sdk library and initialize Qiniu/Storage/UploadManager:

require 'vendor/autoload.php';

use QiniuStorageUploadManager;

// 初始化UploadManager
$uploadManager = new UploadManager();

Next, we can Write a function that processes uploaded images and returns the URL of Qiniu Cloud Storage:

function uploadImage($file, $accessKey, $secretKey, $bucket)
{
    $key = time() . '.' . pathinfo($file['name'], PATHINFO_EXTENSION);
    $token = Qiniuase64_urlSafeEncode("$accessKey:$secretKey");
    
    $uploadMgr = new UploadManager();
    list($ret, $err) = $uploadMgr->putFile($token, $key, $file['tmp_name']);
    
    if ($err !== null) {
        return null;
    } else {
        return "http://yourcdnurl/$key"; // 替换成你自己的CDN域名
    }
}

The above code will upload images to Qiniu Cloud Storage and return the URL of the image. It should be noted that http://yourcdnurl needs to be replaced with your own CDN domain name.

Finally, we can call the uploadImage function to upload the image and return the CDN accelerated URL:

// 设置存储空间的AccessKey和SecretKey
$accessKey = 'your-access-key';
$secretKey = 'your-secret-key';
$bucket = 'your-bucket';

// 处理上传图片
if (isset($_FILES['image'])) {
    $cdnUrl = uploadImage($_FILES['image'], $accessKey, $secretKey, $bucket);
    
    echo 'CDN加速后的图片URL：' . $cdnUrl;
}

The above code will be processed by the uploadImage function Upload the image and return the CDN accelerated URL. Finally, we can display this URL on the page to achieve content distribution and CDN acceleration of images.

Through the above code examples, we can use PHP and Qiniu cloud storage interface to achieve image content distribution and CDN acceleration. With the powerful functions of Qiniu Cloud Storage, the performance and user experience of the website can be greatly improved. Hope this article can be helpful to you!
