Question

我一直在尝试使用Zend框架2书中的教程来设计一个注册页。问题是我在运行它后无法完成注册，点击寄存器会出现套接字错误，我不知道。

    Zend\Http\Client\Adapter\Exception\RuntimeException
    File:
    C:\xampp\htdocs\ZF2AD\Chapter10\client\vendor\zendframework\zend-http\src\Client\Adapter\Socket.php:256
    Message:
    Unable to connect to zf2-api:80 . Error #0: stream_socket_client():unable to connect to zf2-api:80 (php_network_getaddresses: getaddrinfo failed: No such host is known. )

我正在使用Api连接到database.Below是我的Apiclient.php的代码

    }
}

}

改进错误，我知道这是所有错误中的主要错误

    stream_socket_client(): php_network_getaddresses: getaddrinfo failed: No such host is known.

我尝试过在类似问题中提供的解决方案，但他们没有帮助。如果有人知道，请帮助。

错误＃0：stream_socket_client（）：无法连接到zf2-api：80（php_network_getaddresses：getaddrinfo失败：没有这样的主机已知。）
