使用perl写一个调用华为云去创建CDN预热并刷新CDN缓存预热的api接口

以下是使用Perl编写的调用华为云创建CDN预热和刷新CDN缓存预热的API接口的示例代码：

#!/usr/bin/perl

use strict;
use warnings;
use LWP::UserAgent;
use JSON;

# Replace with your own values
my $ak = 'YOUR_ACCESS_KEY';
my $sk = 'YOUR_SECRET_KEY';
my $project_id = 'YOUR_PROJECT_ID';
my $domain_name = 'YOUR_DOMAIN_NAME';

# Create a UserAgent object
my $ua = LWP::UserAgent->new;

# Set the API endpoint URL
my $url = "https://cdn.myhuaweicloud.com/v1.0/$project_id/refresh-tasks";

# Set the request headers
my $headers = [
    'Content-Type' => 'application/json',
    'X-Auth-Token' => '',
];

# Set the request body
my $body = {
    'refresh_type' => 'flush',
    'domains' => [
        $domain_name
    ]
};

# Encode the request body as JSON
my $json_body = encode_json($body);

# Sign the request with the AK/SK
my $timestamp = time;
my $auth_string = "CDN $ak:$timestamp:" . 
    hmac_sha1_hex($timestamp, $sk);
$headers->{'X-Auth-Token'} = $auth_string;

# Send the API request
my $response = $ua->post(
    $url,
    headers => $headers,
    content => $json_body
);

# Check for errors
if ($response->is_error) {
    die "API request failed: " . $response->status_line;
}

# Decode the response body as JSON
my $json_response = decode_json($response->content);

# Print the task ID
my $task_id = $json_response->{'task_id'};
print "Task ID: $task_id\n";

这个示例代码会向华为云发送一个CDN缓存预热的请求，使用了LWP::UserAgent模块发送HTTP请求，使用JSON模块将请求体和响应体编码为和解码为JSON格式。在实际使用中，需要将示例代码中的YOUR_ACCESS_KEY、YOUR_SECRET_KEY、YOUR_PROJECT_ID和YOUR_DOMAIN_NAME替换为自己的实际值。
