如何用python实现openSSL的PHP代码?，pythonopenssl,function get

function getCertId($cert_path) {    $pkcs12certdata = file_get_contents ( $cert_path );    openssl_pkcs12_read ( $pkcs12certdata, $certs, SDK_SIGN_CERT_PWD );    $x509data = $certs ['cert'];    openssl_x509_read ( $x509data );    $certdata = openssl_x509_parse ( $x509data );    $cert_id = $certdata ['serialNumber'];    return $cert_id;}

我写了个Python的版本，使用的是pyopenssl，如下：

'''解析pfx格式的证书ID，这里针对的是签名证书'''def getCertIdWithPFX(cert_path):    fp = open(cert_path, 'r')    if not fp:        raise Exception('open %s fail!!!' % cert_path)    pkcs12certdata = fp.read()    '''先解析pkcs12格式'''    sdk_sign_cert_password = config['sdk_sign_cert_password']    certs = OpenSSL.crypto.load_pkcs12(pkcs12certdata, sdk_sign_cert_password)    '''然后解析x509格式'''    x509data = certs.get_certificate()    print x509data    cert_data = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_ASN1, x509data)    print '-------------------', cert_data    return cert_data.get_serial_number()

问题主要出在x509data，我该如何才能得到x509data中的数据呢，Python中这是个对象。
