关于建行网上支付socket的问题

php 建行网上支付，用socket验签，环境都配好了，一直连不上socket，有大神帮指点一下思路吗

网上银行的链接都是要类似SSL的安全连接的吧，你连接的网关是什么样的？

参考PHP支付接口RSA验证

<?php
$public_key = file_get_contents(dirname(__FILE__).’/rsa_public_key.pem’);
$pkeyid = openssl_pkey_get_public($public_key);
$data = ‘abc’;
$sign = ‘WkMaSsx9Fbj9/YyjoM1X0SLYvaFbsz9VmMaxc42fXxamEEIj5AfqQLrygEZRq0gkLNT4heIwOiSWEAWbfD4imaERKk07ANXEtZJ9jPJvyvg70IVvaYMKAr7bX0dJXmYw4aHnkcWR1kz27Drr6fxPmchB9WCsRmi4VfhVoF1+HRFOp28nIVReGRcbwbW1/bcMisXbitirz9Wq396vY88GUSgbgNdhFXX/kzjRBTjnG+CIhXq4HPdOWovqtPhQoxmK55+V+vxNZk9OPPHHaN3vVswk062NOs2/05yNVObL+PWeg/m43buXYalmkrwEhemdGfjIdNEoSO2D4gikvm43cg==’;
$sign = base64_decode($sign);
if ($pkeyid) {
$verify = openssl_verify($data, $sign, $pkeyid, OPENSSL_ALGO_MD5);
openssl_free_key($pkeyid);
}
var_dump($verify);
?>

外联平台搭建了么？不搭建的话连不上的，我这边报文不知道咋写了。龙支付H5的验签socket回调。也是通过socket
