PHP AWS Cognito'；执行错误"；注册：ResourceNotFoundException:用户池客户端XXXX不存在

当我在项目中实现AWS Cognito时，会出现以下错误

Uncaught exception 'Aws\CognitoIdentityProvider\Exception\CognitoIdentityProviderException' with message 'Error executing "SignUp" on "https://cognito-idp.us-east-1.amazonaws.com"; AWS HTTP error: Client error: `POST https://cognito-idp.us-east-1.amazonaws.com` resulted in a `400 Bad Request` response: {"__type":"ResourceNotFoundException","message":"User pool client XXXX does not exist."} ResourceNotFoundException (client): User pool client XXXX does not exist. - {"__type":"ResourceNotFoundException","message":"User pool client XXXX does not exist."}' GuzzleHttp\Exception\ClientException: Client error: `POST https://cognito-idp.us-east-1.amazonaws.com` resulted in a `400 Bad Request` response: {"__type":"ResourceNotFoundException","message":"User pool client XXXX does not exist."} in /vendor/aws/aws-sdk-php/src/WrappedHttpHandler.php on line 191

我使用了以下URL：

这是我的PHP代码：

这是config.php文件

$config = [
'credentials' => [
    'key' => 'XXXXXXXXXXXXXXXX',
    'secret' => 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
],
'region' => 'XXXXXXXXXXXXXXXX',
'version' => 'latest',
'app_client_id' => 'XXXXXXXXXXXXXXXX',
'app_client_secret' => 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
'user_pool_id' => 'XXXXXXXXXXXXXXXX'];

require './vendor/autoload.php';

$aws = new \Aws\Sdk($config);
$cognitoClient = $aws->createCognitoIdentityProvider();
$client = new \pmill\AwsCognito\CognitoClient($cognitoClient);
$client->setAppClientId($config['app_client_id']);
$client->setAppClientSecret($config['app_client_secret']);
$client->setRegion($config['region']);
$client->setUserPoolId($config['user_pool_id']);
return $client;

如果您传递的客户端id实际上不存在，则会引发错误。 可能用户池是在不同的区域中创建的，或者配置参数错误

$config = [
'credentials' => [
    'key' => 'XXXXXXXXXXXXXXXX',
    'secret' => 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
],
'region' => 'XXXXXXXXXXXXXXXX',
'version' => 'latest',
'app_client_id' => 'XXXXXXXXXXXXXXXX',
'app_client_secret' => 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
'user_pool_id' => 'XXXXXXXXXXXXXXXX'];

require './vendor/autoload.php';

$aws = new \Aws\Sdk($config);
$cognitoClient = $aws->createCognitoIdentityProvider();
$client = new \pmill\AwsCognito\CognitoClient($cognitoClient);
$client->setAppClientId($config['app_client_id']);
$client->setAppClientSecret($config['app_client_secret']);
$client->setRegion($config['region']);
$client->setUserPoolId($config['user_pool_id']);
return $client;
