How PHP connects with Tencent Cloud CDN acceleration service to achieve static resource acceleration function

With the rapid development of the Internet, website access speed has become one of the important indicators of user experience. In traditional website architecture, the loading speed of static resources is often affected, resulting in slower page loading. In order to solve this problem, Tencent Cloud provides a CDN acceleration service, which can help developers speed up the loading of static resources and improve the website access experience.

This article will introduce how to use PHP language to connect to Tencent Cloud CDN acceleration service to realize the function of static resource acceleration. First, we need to activate the CDN acceleration service in the Tencent Cloud console and obtain the corresponding API key.

1. SDK preparation

In order to facilitate the use of the API interface of Tencent Cloud CDN, we can use the SDK provided by Tencent Cloud to simplify the development process. In this example, we use Tencent Cloud CDN’s PHP SDK. You can install it through Composer and execute the following command:

composer require qcloud/cos-sdk-v5

2. Configure API key

Before using the CDN SDK, we need to configure the API key so that we can Authentication. Create a new config.php file in the project and add the following code:

<?php

return [
    'cdn' => [
        'region' => 'ap-guangzhou',
        'secretId' => 'your-secretId',
        'secretKey' => 'your-secretKey',
    ],
];

Make sure to replace your-secretId and your-secretKey with those you control in Tencent Cloud The corresponding key obtained in Taichung.

3. Implementing the upload function

Next, we need to implement the function of uploading files to Tencent Cloud CDN. Create a new upload.php file in the project and add the following code:

<?php

require_once 'vendor/autoload.php';
$config = require_once 'config.php';

use QcloudCosClient;

// 初始化腾讯云CDN客户端
$cdnClient = new Client([
    'region' => $config['cdn']['region'],
    'credentials' => [
        'secretId' => $config['cdn']['secretId'],
        'secretKey' => $config['cdn']['secretKey'],
    ],
]);

// 上传文件到CDN
function uploadToCDN($cdnClient, $bucket, $localFile, $remoteFile) {
    try {
        $result = $cdnClient->putObject([
            'Bucket' => $bucket,
            'Key' => $remoteFile,
            'Body' => fopen($localFile, 'rb'),
        ]);

        // 返回文件的CDN访问URL
        return $result['ObjectURL'];
    } catch (Exception $e) {
        // 处理异常
        echo $e->getMessage();
    }
}

// 设置要上传的文件路径
$localFile = 'path/to/local/file.jpg';
// 设置CDN中保存的远程文件名
$remoteFile = 'cdn/file.jpg';
// 设置CDN的存储桶名称
$bucket = 'your-bucket';

// 调用上传函数
$cdnUrl = uploadToCDN($cdnClient, $bucket, $localFile, $remoteFile);

echo "上传成功：<img src='{$cdnUrl}' />";

Make sure to add path/to/local/file.jpg, cdn/file.jpg## Replace # and your-bucket with your actual path and bucket name.
