Practice of using PHP and Qiniu cloud storage interface to upload files

Introduction:
With the development of cloud storage technology, more and more applications are beginning to store files in the cloud. Achieve high availability and easy access to data. Qiniu Cloud Storage, as a well-known cloud storage platform, provides a wealth of interfaces and functions to facilitate developers to upload and manage files. This article will introduce how to use PHP and Qiniu cloud storage interface to upload files, and provide relevant code examples.

1. Register a Qiniu Cloud Storage account and create a storage space

Before using Qiniu Cloud Storage, you need to register a Qiniu Cloud account and create a storage space. Assume that we have successfully registered and obtained the AccessKey and SecretKey of Qiniu Cloud Storage.

2. Install the PHP SDK of Qiniu Cloud Storage

Qiniu Cloud Storage provides a rich SDK for use by different programming languages. In this practice, we use the PHP programming language to upload files, so we need to install the PHP SDK of Qiniu Cloud Storage.

1. Use Composer to install

Open a terminal or command prompt, navigate to your project directory, and execute the following command to install the PHP SDK of Qiniu Cloud Storage:

composer require qiniu/php-sdk

2. Or manually download the SDK file

If you don’t use Composer, you can also manually download the PHP SDK of Qiniu Cloud Storage. You can find the relevant repository on GitHub, download and extract it to your project directory.

3. Write the code for uploading files

After we install the PHP SDK of Qiniu Cloud Storage, we can use the interfaces and methods to upload files. The following is a simple code example for uploading files:

<?php
require_once 'vendor/autoload.php'; // 如果使用Composer安装，需要引入autoload.php文件

use QiniuAuth; // 引入七牛云存储的Auth类
use QiniuStorageUploadManager; // 引入七牛云存储的UploadManager类

$accessKey = 'your-access-key'; // 替换为你的七牛云存储AccessKey
$secretKey = 'your-secret-key'; // 替换为你的七牛云存储SecretKey
$bucket = 'your-bucket'; // 替换为你的存储空间名称

$auth = new Auth($accessKey, $secretKey);
$token = $auth->uploadToken($bucket);

$uploadMgr = new UploadManager();

$filePath = '/path/to/your/file.jpg'; // 替换为你要上传的文件路径
$key = 'your-file-key.jpg'; // 替换为你要保存的文件在七牛云存储上的命名

list($ret, $err) = $uploadMgr->putFile($token, $key, $filePath);

if ($err !== null) {
    echo '上传失败';
} else {
    echo '上传成功';
}
?>

It should be noted that "your-access-key", "your-secret-key", "your-bucket", "/ path/to/your/file.jpg" and "your-file-key.jpg" need to be replaced according to the actual situation.

4. Run the code for file upload

Save the above code into a PHP file and use a web server to run the file (for example: use Apache or Nginx as the web server). Access the URL of the file in your browser. If everything goes well, you should be able to see the output "Upload successful".

Summary:
This article introduces the practice of using PHP and Qiniu Cloud Storage interface to upload files. Register a Qiniu Cloud Storage account and create a storage space, install Qiniu Cloud Storage's PHP SDK, write the code to upload files, and run the code to upload files. I hope this article can help readers understand the file upload function of Qiniu Cloud Storage and be able to apply it in actual projects.
