AWS PHP SDK-如何为联合用户生成用于登录的终端节点？

如何解决AWS PHP SDK-如何为联合用户生成用于登录的终端节点？

有人可以帮助我使用 AWS STS getFederationToken API为联盟用户生成登录端点吗？

以下是我的代码-

<?PHP
require 'aws-autoloader.PHP';
use Aws\Sts\StsClient; 
use Aws\Sts\Exception\StsException;

$credentials = new Aws\Credentials\Credentials('MYKEY','MYSECRET');

$client = new StsClient([
    'region' => 'ap-south-1','version' => '2011-06-15','credentials' => $credentials
]);


try {
    
    $result = $client->getFederationToken(array(
    // Name is required
    'Name' => 'sv','Policy' => '{
  "Version": "2012-10-17","Statement": [
    {
      "Action": [
    "sns:*"
      ],"Effect": "Allow","Resource": "*"
    }
  ]
}','DurationSeconds' => 28000,));

    //echo '<pre>'; print_r($result);die;
   

$json_data = json_encode(['sessionId' => '$result["Credentials"]["AccessKeyId"]','sessionKey' => '$result["Credentials"]["SecretAccessKey"]','sessionToken' => '$result["Credentials"]["SessionToken"]'
]);

$issuer = urlencode("https://signin.aws.amazon.com/");

$destination = urlencode("https://console.aws.amazon.com/sns");

$sign_in_url = "https://signin.aws.amazon.com/federation?Action=getSigninToken&SessionType=json&Session=".urlencode($json_data);

$ch = curl_init();

// Will return the response,if false it print the response
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
// Set the url
curl_setopt($ch,CURLOPT_URL,$sign_in_url);
// Execute
$result=curl_exec($ch);

// Closing
curl_close($ch);

// Print the return data
$res = json_decode($result,true);

$sign_in_token = $res['SigninToken'];

$login_url = "https://signin.aws.amazon.com/federation?Action=login&Issuer=".$issuer."&Destination=".$destination."&SigninToken=".$sign_in_token;

echo $login_url;

} catch (StsException $e) {
    // output error message if fails
    print_r($e->getMessage());
}
