問(wèn)題

最近在寫(xiě)博客瀏覽量的時(shí)候，設(shè)計(jì)了這么一個(gè)邏輯：同一個(gè)IP瀏覽一遍文章，5分鐘內(nèi)不刷新次數(shù)。就需要在服務(wù)器端得到用戶(hù)的真實(shí)IP，我代碼是這樣寫(xiě)的(從網(wǎng)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(fā)現(xiàn)得到的IP總172開(kāi)頭的IP，我查了下是本地局域網(wǎng)的IP，我的項(xiàng)目又是docker布署的，這又記我聯(lián)想到docker內(nèi)部的IP。。。

解決辦法

最后才發(fā)現(xiàn)nginx代理接口的時(shí)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(qǐng)求真實(shí)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(wèn)題解決！

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
