PHP Authentication and identity verification methods in Huawei Cloud API interface docking

With the rapid development of cloud computing, more and more developers choose to deploy applications on cloud platforms. As a leading cloud service provider in China, Huawei Cloud provides developers with rich API interfaces to quickly build and expand applications. When developing using Huawei Cloud API interfaces, authentication and identity verification are required. This article will introduce how to perform authentication and identity verification of Huawei Cloud API interface in PHP, and provide code examples.

1. Generate access key

Before connecting to the Huawei Cloud API interface, developers need to generate an access key on the Huawei Cloud console. The specific steps are as follows:

1.1 Log in to the Huawei Cloud console and enter the "My Credentials" page.
1.2 Click "Access Key Management" and then select "Create Access Key".
1.3 Enter the name in the pop-up dialog box and select the key type.
1.4 Click "Confirm", the system will generate the access key and provide the key ID and key.

2. Authentication and Identity Verification

When calling the Huawei Cloud API interface, you need to use the generated access key for authentication and identity verification. The following is a sample code for authentication and authentication using PHP:

<?php
// 访问密钥
$accessKeyId = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$accessKeySecret = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';

// 请求参数
$method = 'GET';
$apiEndpoint = 'https://ecs.cn-north-1.myhuaweicloud.com/v1/xxxxxxxxxxxxxx';

// 生成请求时间戳和日期
$date = gmstrftime('%Y%m%dT%H%M%SZ', time());
$timestamp = gmstrftime('%Y%m%dT%H%M%SZ', time());

// 构造待签名字符串
$canonicalRequest = $method . "
" .
    '' . "
" .
    '' . "
" .
    $date . "
" .
    $apiEndpoint;

// 计算签名
$signString = base64_encode(hash_hmac('sha256', $canonicalRequest, $accessKeySecret, true));

// 发起请求
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $apiEndpoint);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'X-Auth-Signature: ' . $signString,
    'X-Auth-Accesskey: ' . $accessKeyId,
    'X-Auth-Date: ' . $timestamp
));
$response = curl_exec($curl);
curl_close($curl);

// 处理响应结果
var_dump($response);
?>

In the code, you first need to configure the access key and request parameters. Then, authentication and identity verification are performed by constructing the string to be signed and calculating the signature. Finally, use the curl library to initiate a request and process the returned response.

Please note that the above example code is just a simplified example, and actual use may need to be appropriately adjusted according to specific scenarios and interface requirements.

Summary:

This article introduces the authentication and identity verification method of Huawei Cloud API interface in PHP. By generating access keys in the Huawei Cloud console and using PHP code for authentication and identity verification, developers can safely call Huawei Cloud API interfaces. I hope this article can provide developers with some help and guidance in cloud platform development.
