最近升级了证书，这个接口偶尔会出错：https://api.mch.weixin.qq.com/pay/unifiedorder
返回报文如下：

请求报文部分如下
<spbill_create_ip>10.151.174.11, 117.136.31.41spbill_create_ip>

IP地址得是单IP，你的样本数据需要从逗号处分割，例如 10.151.174.11, 117.136.31.41 取第一个或者第二个都可以。
public String getIpAddr() {String ip = request.getHeader("x-forwarded-for");if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("WL-Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getRemoteAddr();}if (ip.indexOf(",") != -1) {String[] ips = ip.split(",");if (ips.length > 1) {ip = ips[0];}}return ip;}
