最近在写博客浏览量的时候,设计了这么一个逻辑:同一个IP浏览一遍文章,5分钟内不刷新次数。就需要在服务器端得到用户的真实IP,我代码是这样写的(从网上找的方法):
public static String getRealIp(HttpServletRequest request) {
String ip = request.getHeader("x-forwarded-for");
String unknown = "unknown";
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.getHeader("HTTP_CLIENT_IP");
}
if (ip == null || ip.length() == 0 || unknown.equalsIgnoreCase(ip)) {
ip = request.getHeader("HTTP_X_FORWARDED_FOR");
}
if (ip == null || ip.length() == 0 || unknown.equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
}
return ip;
}
发现得到的IP总172开头的IP,我查了下是本地局域网的IP,我的项目又是docker布署的,这又记我联想到docker内部的IP。。。
最后才发现nginx代理接口的时候,需要做获取IP的配置
location ^~ /api {
proxy_pass http://127.0.0.1:8110/;
proxy_read_timeout 90;
#得到请求真实IP
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header HTTP_X_FORWARDED_FOR $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_redirect default;
}
加上面面的配置,问题解决!
