Php 在AWS中使用cognito调用未定义的成员函数adminInitiateAuth（）

我通过创建下面给出的函数来使用相同的代码：

$this->client = new CognitoIdentityProviderClient([
  'version' => '2016-04-18',
  'region' => 'us-east-1',
]);
$result = $this->client->adminInitiateAuth([
    'AuthFlow' => 'ADMIN_NO_SRP_AUTH',
    'ClientId' => $this->client_id,
    'UserPoolId' => $this->userpool_id,
    'AuthParameters' => [
        'USERNAME' => 'xxxx',
        'PASSWORD' => 'xxxxxx',
    ],
]);

我创建了一个RESTAPI调用并调用了这个函数。我收到对未定义成员adminInitiateAuth的错误调用。我已经在.env fileClientID、Region、userpoolID中声明了凭据

我已初始化$this->client，如下所示：

public function authenticate(string $username, string $password) : string
    {
        try {
            $result = $this->client->adminInitiateAuth([
                'AuthFlow' => 'ADMIN_NO_SRP_AUTH',
                'ClientId' => $this->client_id,
                'UserPoolId' => $this->userpool_id,
                'AuthParameters' => [
                    'USERNAME' => $username,
                    'PASSWORD' => $password,
                ],
            ]);
        } catch (\Exception $e) {
            return $e->getMessage();
        }

        $this->setAuthenticationCookie($result->get('AuthenticationResult')['AccessToken']);

        return '';
    }

请查找完整的课程代码：

public function initialize() : void
    {
        $this->client = new CognitoIdentityProviderClient([
          'version' => '2016-04-18',
          'region' => $this->region,
        ]);

        try {
            $this->user = $this->client->getUser([
                'AccessToken' => $this->getAuthenticationCookie()
            ]);
        } catch(\Exception  $e) {
            // an exception indicates the accesstoken is incorrect - $this->user will still be null
        }
    }

我找到了一个您可能想查看的引用。

在调用authenticate之前是否启动了$this->client？是@AgeValed。公共函数初始化：void{$this->client=new CognitoIdentityProviderClient['version'=>'2016-04-18'，'region'=>$this->region，]；尝试{$this->user=$this->client->getUser['AccessToken'=>$this->getAuthenticationCookie]；}catch\Exception$e{//Exception表示accesstoken不正确-$this->user仍然为null}}，所以您正在执行以下操作$test=新类名$测试->初始化//或者可以从_构造函数$test->authenticate'user'，'pass'调用此函数@IMLOKESH尝试公共函数构造而不是公共函数初始化。我也在u构造下检查过。但同样的错误也发生了@亚历克斯哈里斯

    $this->client = CognitoIdentityProviderClient::factory([
        'region' => $region,
        'version' => $version
    ]);

    $result = $this->client->adminInitiateAuth([
        'UserPoolId'     => $this->poolId,
        'ClientId'       => $this->clientId,
        'AuthFlow'       => 'ADMIN_NO_SRP_AUTH', // this matches the 'server-based sign-in' checkbox setting from earlier
        'AuthParameters' => [
            'USERNAME' => $username,
            'PASSWORD' => $password
        ]
    ]);
