問題

最近在寫博客瀏覽量的時候，設計了這么一個邏輯：同一個IP瀏覽一遍文章，5分鐘內不刷新次數。就需要在服務器端得到用戶的真實IP，我代碼是這樣寫的(從網上找的方法)：

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;}

發現得到的IP總172開頭的IP，我查了下是本地局域網的IP，我的項目又是docker布署的，這又記我聯想到docker內部的IP。。。

解決辦法

最后才發現nginx代理接口的時候，需要做獲取IP的配置

location ^~ /api { proxy_pass http://127.0.0.1:8110/; proxy_read_timeout 90; #得到請求真實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，問題解決！
