Sharing of practical experience in interface docking between PHP and Huawei Cloud Platform

With the rapid development of cloud computing, more and more developers are beginning to use cloud platforms to build their own applications. As one of the cloud service providers, Huawei Cloud Platform provides a wealth of services and API interfaces, allowing developers to easily deploy their applications to the cloud. This article will share my practical experience in connecting the interface between PHP and Huawei Cloud Platform, and attach some code examples.

First, we need to create a project on the Huawei Cloud Platform and obtain the Access Key and Secret Key of the project. These keys will be used for authentication to ensure that we can access Huawei Cloud Platform services through APIs.

Next, we need to use PHP to write code to implement the interface with Huawei Cloud Platform. Below is a simple example showing how to create a cloud server through an API request.

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

use GuzzleHttpClient;
use GuzzleHttpExceptionClientException;

$accessKey = 'your_access_key';
$secretKey = 'your_secret_key';
$projectId = 'your_project_id';

$httpClient = new Client([
    'base_uri' => 'https://ecs.myhuaweicloud.com/v1/'
]);

try {
    $response = $httpClient->post('cloudservers', [
        'headers' => [
            'X-Auth-Project-Id' => $projectId,
            'X-Auth-Token' => getAuthToken($accessKey, $secretKey),
            'Content-Type' => 'application/json'
        ],
        'json' => [
            'server' => [
                'name' => 'my-server',
                'imageRef' => 'your_image_id',
                'flavorRef' => 'your_flavor_id',
                'key_name' => 'your_key_pair_name',
                'availability_zone' => 'your_availability_zone'
            ]
        ]
    ]);

    $server = json_decode($response->getBody(), true)['server'];
    echo 'Created server with ID: ' . $server['id'];
} catch (ClientException $e) {
    echo 'Error creating server: ' . $e->getMessage();
}

function getAuthToken($accessKey, $secretKey)
{
    $timestamp = gmdate('YmdTHisZ');
    $method = 'POST';
    $host = 'ecs.myhuaweicloud.com';
    $uri = '/v1/{project_id}/cloudservers';

    $signature = base64_encode(hash_hmac('sha256', $method . "
" . $timestamp . "
" . str_replace('{project_id}', $projectId, $uri) . "
", $secretKey, true));
    return "SDK-HMAC-SHA256 Access=$accessKey, SignedHeaders=content-type;host;x-auth-project-id;x-auth-timestamp, Signature=$signature";
}

The above code uses the Guzzle Http client library to make API requests. First, we need to set the Access Key and Secret Key to the corresponding values. Then, we created an Http client and created a cloud server via POST request. In the request header, we need to set X-Auth-Token for authentication, and specify application/json through Content-Type. In the request body, we pass some necessary parameters, such as server name, image ID, specification ID, etc.

In addition, we found that during the request authentication process, we need to sign the Access Key, Secret Key and some other information and splice them into the X-Auth-Token in the request header. Here we implement a getAuthToken function to generate authentication information.

The above is just a simple example. In actual use, you need to choose which API interfaces to use and which parameters to pass based on specific business needs. Huawei Cloud Platform provides rich API documents and SDKs to help developers better understand and use the services they provide.

To sum up, the interface between PHP and Huawei Cloud Platform is not complicated. You only need to choose the appropriate HTTP client library to send API requests and follow the authentication rules. Through this article, I believe that readers have a certain understanding of the interface between PHP and Huawei Cloud Platform, and can use this knowledge in their own projects. Hope this article is helpful to you!
