生成 AWS 签名 (ShipLogic)

Question

所以我在我的程序中实现了 ship-logic 的 API，并且从未使用过 AWS 身份验证。 我是否对文档进行了研究并做了以下工作：

<?php
$host = "api.shiplogic.com";
$accessKey = 'AKIA55D5DNTBFC3I7BHQ';
$secretKey = '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';
$requestUrl = 'https://api.shiplogic.com';
$uri = '/rates';
$httpRequestMethod = 'POST';
$data = '{"collection_address": {"company": "Kenesis Test","street_address": " 32 Goud Street, Goedeburg, Benoni","local_area": "Benoni","city": "Johannesburg","country": "ZA","code": "1501"},"delivery_address": {"street_address": "10 bloomberg street","local_area": "minnebron","city": "brakpan","code": "1541"},"parcels": [{"submitted_length_cm": 1,"submitted_width_cm": 1,"submitted_height_cm": 1,"submitted_weight_kg": 0.1}],"declared_value": 99}';;

require 'vendor/autoload.php';
use Aws\Signature\SignatureV4;
use Aws\Credentials\Credentials;
use GuzzleHttp\Client;
use GuzzleHttp\Psr7\Request;
use Psr\Http\Client\ClientInterface;

$signature = new SignatureV4('execute-api', 'af-south-1');
$credentials = new Credentials($accessKeyId, $secretAccessKey);
$psr7Request = new Request($httpRequestMethod, $requestUrl.$uri, ["content-type"=>"application/json"], $data);
$client = new Client([$requestUrl, 'timeout' => 30]);
$sr = $signature->signRequest($psr7Request, $credentials);
$response = $client->send($sr);

//var_dump($response);
?>

现在它是一段简单的代码，但我不断收到 403 响应。 当我使用 PostMan 执行完全相同的请求时，响应成功返回。

任何 AWS 专家都可以帮助我并指出我是否在代码方面做错了什么？ 我们将不胜感激。

P.S，我在这里使用沙盒凭据，不用担心。

这是一个标题问题。发送请求时需要包含以下标头。

$amzDate = date('Ymd\THis\Z');
$headers = [
'X-Amz-Date'   => $amzDate,
'Cookie'       => 'XDEBUG_SESSION=PHPSTORM',
'Content-Type' => 'application/json',
];
