How to use PHP and Youpai Cloud API to realize the functions of encrypted transmission and secure transmission of files

With the enhancement of information security awareness, protecting the security of file transmission has become very important. As a professional cloud storage service provider, Paiyun provides a rich API interface to realize file upload, download and management functions. In this article, we will introduce how to use PHP and Youpai Cloud API to realize the functions of encrypted transmission and secure transmission of files.

First, we need to create a storage space on Youpai Cloud and obtain the corresponding API key. Before using the API, we need to install and introduce Youpaiyun's SDK library. It can be installed through composer:

composer require upyun/upyun-php-sdk

The following is a sample code for uploading files using Youpaiyun API:

<?php
require_once 'vendor/autoload.php';

$service = new UpyunService('your_bucketname', 'your_operatorname', 'your_password');

// 上传文件
$remotePath = '/test/upload/file.jpg';
$localPath = '/path/to/file.jpg';
$options['content-secret'] = 'your_content_secret'; // 加密传输密钥
$response = $service->upload($remotePath, fopen($localPath, 'r'), $options);

if ($response->isOk()) {
    echo '文件上传成功！';
} else {
    echo '文件上传失败：' . $response->getStatusCode() . ' ' . $response->getReasonPhrase();
}
?>

The above code first introduces Youpaiyun's SDK library and creates A service object that captures the cloud again. You need to replace your_bucketname, your_operatorname and your_password with your own values. Next, we use the upload method to upload the file, where $remotePath is the path where the file is saved on Youpai Cloud, and $localPath is the path to the local file. . In addition, we can also set some options through the $options parameter, such as the encrypted transmission key content-secret.

When the file is uploaded successfully, we can use $response->isOk() to determine whether the upload is successful and obtain the status code and reason phrase.

Next, we will introduce how to perform secure transmission. Youpaiyun provides secure transmission based on HTTPS protocol. When using the API, just replace http in the API address with https. The following is a sample code for uploading files using HTTPS:

<?php
require_once 'vendor/autoload.php';

$service = new UpyunService('your_bucketname', 'your_operatorname', 'your_password', ['protocol' => 'https']);

// 上传文件
$remotePath = '/test/upload/file.jpg';
$localPath = '/path/to/file.jpg';
$response = $service->upload($remotePath, fopen($localPath, 'r'));

if ($response->isOk()) {
    echo '文件上传成功！';
} else {
    echo '文件上传失败：' . $response->getStatusCode() . ' ' . $response->getReasonPhrase();
}
?>

In the above code, when we create the Service object, we pass in a protocol# through the $options parameter. ## option, set to https. In this way, files uploaded through the upload method will be transmitted through the HTTPS protocol, achieving the purpose of secure transmission.

Through the above code examples, we can use PHP and Youpai Cloud API to implement the functions of encrypted transmission and secure transmission of files. In practical applications, we can also combine other functions, such as file encryption, access control, etc., to further protect file security.
