Question

我正在开发一个我有服务器的项目。服务器连接到Amazon-Cognito以获取Identity Id和令牌。这是我的PHP代码。

test.php的：

include 'aws.phar';

//require 'vendor/autoload.php';
use Aws\CognitoIdentity\CognitoIdentityClient;
use Aws\Sts\StsClient;
use Aws\Credentials\Credentials;
use Aws\S3\S3Client;

echo "OK";

$Client = CognitoIdentityClient::factory(array(
  'version' => 'latest',
  'profile' => 'project1',
  'region'  => 'ap-northeast-1'
));

$result = $Client->getOpenIdTokenForDeveloperIdentity(array(
  'IdentityPoolId' => 'xxxxxxxxxxxx',

  'Logins' => array(
    'login.blupinch.app' => 'sandesh-004',
  ),
  'TokenDuration' => 3600,
));

echo $token = $result['Token'];
//echo null;

当我打开浏览器并输入服务器的URL时，我只能看到“OK”，但不能看到$token的值。有趣的是，如果我从命令行执行此操作，我可以看到“OK”和$token值：

php test.php

为什么会这样？为什么我看不到$token的价值？

更新：当我运行“php test.php”时。我可以看到令牌的回声。就像这个

ubuntu @ ip-172-31-30-222：/ var / www / html $ php test.php

Answer 1

使用代码

echo $token = $result['Token'];

您只是回显将$ result ['Token']的值赋给$ token的布尔结果。看起来你应该引用'TokenDuration'

你需要这样做

$token = $result['TokenDuration'];
echo $token;

Answer 2

这不会输出真，这不会是什么。

echo $token = $result['Token'];

Answer 3

echo $token = !empty($result['Token']) ? $result['Token'] : "Token is empty";

添加AWS标头
