How PHP connects to Tencent Cloud Object Storage Service to implement image upload function

Introduction:
With the rapid development of the Internet, more and more applications require file upload, the most common of which is Image upload function. In order to provide high-availability, high-reliability, and high-performance image upload services, many developers choose to use cloud storage services. Tencent Cloud provides a cloud storage service called Object Storage (COS). This article will introduce how to use PHP language to connect to Tencent Cloud Object Storage Service to implement the image upload function.

1. Obtain the Tencent Cloud API key
Before using the Tencent Cloud object storage service, we first need to obtain the Tencent Cloud API key. The specific steps to obtain the key are as follows:

1. Log in to Tencent Cloud official website (https://cloud.tencent.com/).
2. Enter "Console" and click "Object Storage COS" to enter the COS console.
3. In the COS console, select "Access Management" - "API Key Management" in the left navigation bar. You can obtain the SecretId and SecretKey here, which will be used for authentication in subsequent codes. .

2. Directory structure preparation
Before we start writing code, we need to prepare the directory structure of the project. A simple directory structure looks like this:

• project

  • index.php

  • cos-php-sdk-v5

    • src

      • Qcloud

        • Cos

          • CosClient. php
  • #upload
    upload.php

Among them:

index.php is the file used to display the image upload interface;
• cos- php-sdk-v5 is the PHP SDK officially provided by Tencent Cloud, used to interact with Tencent Cloud object storage service;
• upload directory is used to store uploaded images;
• upload.php Is the background code used to process uploaded images.

3. Install PHP SDK

In order to use Tencent Cloud Object Storage Service, we need to download and install PHP SDK. You can download the latest version from Tencent Cloud's official GitHub repository (https://github.com/tencentyun/cos-php-sdk-v5).

Extract the downloaded compressed package and copy the "src" folder to the "cos-php-sdk-v5" folder in the project directory. The project directory structure is as follows:

• project
  index.php
  • cos-php-sdk-v5
    • src
      • Qcloud
        • Cos
          CosClient.php
  ##upload

  • upload.php
4. Write the front-end code

Next, we start writing the front-end code. In the index.php file, we can use HTML and CSS to design a simple image upload interface:

<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="上传" name="submit">

In the file form, we set the file upload request address to "upload/upload.php". This address will be used by the code behind that handles uploading images.

5. Writing background code

In the upload.php file, we need to write code to connect to Tencent Cloud Object Storage Service and upload images. The specific code is as follows:

require_once '../cos-php-sdk-v5/src/Qcloud/Cos/CosClient.php';

use QcloudCosCosClient;

// Tencent Cloud API key

$secretId = 'your-secret-id';

$secretKey = 'your-secret-key';

// COS service configuration

$bucket = 'your-bucket-name';

$region = 'your-bucket-region';

// Instantiate CosClient

$cosClient = new CosClient([

'region' => $region,
'credentials' => [
    'secretId' => $secretId,
    'secretKey' => $secretKey
]

]);

// Process image upload

if ($_FILES'fileToUpload' === UPLOAD_ERR_OK) {

$key = '/upload/' . $_FILES['fileToUpload']['name'];
$localPath = $_FILES['fileToUpload']['tmp_name'];

try {
    $result = $cosClient->putObject([
        'Bucket' => $bucket,
        'Key' => $key,
        'Body' => fopen($localPath, 'rb')
    ]);

    echo '图片上传成功，访问URL为：' . $result['ObjectURL'];
} catch (Exception $e) {
    echo '图片上传失败，错误信息：' . $e->getMessage();
}

} else {

echo '图片上传失败，错误码：' . $_FILES['fileToUpload']['error'];

}

?>

Among them, the parts that need to be replaced are:

$secretId: Replace it with your Tencent Cloud API key SecretId in;

• $secretKey: Replace it with the SecretKey in your Tencent Cloud API key;
• $bucket: Replace it with the bucket name of your Tencent Cloud COS service;
• $region: Replace with the region where the bucket of your Tencent Cloud COS service is located.
• 6. Run the test

Deploy the entire project to the web server, and access the index.php file in the browser to see the interface for uploading images. Click the "Select File" button to select an image file, and then click the "Upload" button to upload the image to Tencent Cloud Object Storage Service.

Summary:

Through the above steps, we successfully used PHP language to connect to Tencent Cloud Object Storage Service to implement the image upload function. Through cloud storage services, we can provide highly available and highly reliable image upload services to meet the needs of various applications. Of course, in addition to image upload, Tencent Cloud Object Storage Service also supports the upload and download of other file types and can be expanded according to specific needs.
