3. Calling Amazon API to get product ratings and reviews

It is very simple to call Amazon API using Amazon AWS SDK for PHP. Here is a sample code to get product ratings and reviews:

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

use AwsCredentialsCredentials;
use AwsSignatureSignatureV4;
use AwsSdk;

$accessKeyId = 'YOUR_ACCESS_KEY_ID';
$secretAccessKey = 'YOUR_SECRET_ACCESS_KEY';
$region = 'us-west-2'; // 根据实际情况选择区域

$credentials = new Credentials($accessKeyId, $secretAccessKey);

$config = [
    'region' => $region,
    'version' => 'latest',
    'credentials' => $credentials,
];

$sdk = new Sdk($config);

$service = $sdk->createAwsService([
    'service' => 'execute-api',
]);

$request = $service->createRequest([
    'httpMethod' => 'GET',
    'url' => 'https://api.amazon.com/your/api/endpoint', // 替换成实际的API地址
    'headers' => [
        'Host' => 'api.amazon.com',
    ],
    'endpoint' => 'https://api.amazon.com',
]);

$signer = new SignatureV4('execute-api', $region);
$request = $signer->signRequest($request, $credentials);

$response = $service->executeRequest($request);
$data = $response->toArray();

// 处理返回的数据
// ...

?>

Please replace YOUR_ACCESS_KEY_ID and YOUR_SECRET_ACCESS_KEY in the code with the actual API key.

https://api.amazon.com/your/api/endpoint in the code indicates the specific address for calling the Amazon API, which should be modified according to actual needs.

4. Processing the returned data

The data returned by the Amazon API is a JSON object containing product evaluation and review information. We can use PHP related functions to parse and process it. . According to actual needs, you can use the json_decode function to convert JSON data into a PHP array, and then process and display it as required.
