生成签名时

openssl_get_privatekey

$priKey = "-----BEGIN RSA PRIVATE KEY-----\n" .
    wordwrap($priKey, 64, "\n", true) .
    "\n-----END RSA PRIVATE KEY-----";
$res = openssl_get_privatekey($priKey);

========

验证签名时
如果上传的文件就是支付宝后台下载的公钥（不带头尾的一行字符串），
那不需要再用

openssl_get_publickey

获取一次了。。

$res = "-----BEGIN PUBLIC KEY-----\n" .
    wordwrap($pubKey, 64, "\n", true) .
    "\n-----END PUBLIC KEY-----";
file_put_contents(HOME_DIR.‘/pay_alipayqrcode_callback.txt‘,date("Y-m-d H:i:s")."-pubKey:"."\r\n".var_export($res,true)."\r\n",FILE_APPEND);
//$res = openssl_get_publickey($pubKey);不需要再获取一次了。。

openssl_get_publickey适用于文件如下格式的
格式如这样的
