服务器怎么绑定ip(云服务器怎么绑定多个IP)

你把这个方法写进你的程序,程序开始后先获取IP,然后判断IP是否和你的一致,如果不一致直接return;即可.

/**

* 获取外网IP

* @param request

* @return

*/

public static String getIpAddr() {

String ipAddress = null;

// ipAddress = this.getRequest().getRemoteAddr();

ipAddress = request.getHeader("x-forwarded-for");

if (ipAddress == null || ipAddress.length() == 0

|| "unknown".equalsIgnoreCase(ipAddress)) {

ipAddress = request.getHeader("Proxy-Client-IP");

}

if (ipAddress == null || ipAddress.length() == 0

|| "unknown".equalsIgnoreCase(ipAddress)) {

ipAddress = request.getHeader("WL-Proxy-Client-IP");

}

if (ipAddress == null || ipAddress.length() == 0

|| "unknown".equalsIgnoreCase(ipAddress)) {

ipAddress = request.getRemoteAddr();

if (ipAddress.equals("127.0.0.1")) {

// 根据网卡取本机配置的IP

InetAddress inet = null;

try {

inet = InetAddress.getLocalHost();

} catch (UnknownHostException e) {

e.printStackTrace();

}

ipAddress = inet.getHostAddress();

}

}

// 对于通过多个代理的情况，第一个IP为客户端真实IP,多个IP按照','分割

if (ipAddress != null && ipAddress.length() > 15) { // "***.***.***.***".length()

// = 15

if (ipAddress.indexOf(",") > 0) {

ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));

}

}

return ipAddress;

}
