服務器怎么獲取客戶端ip地址？

一般nginx要獲取真實ip需要location段加上

proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

當然也要視實際情況而定

不應該是客戶端請求nginx拿到vue頁面，然后vue頁面再請求nginx,然后ngix將請求轉發(fā)到tomcat，tomcat返回數(shù)據(jù)嗎？vue直接透過nginx訪問tomcat這樣不好吧。

上面的大兄弟說了nginx的配置。我提供下java中獲取ip地址代碼，參考下：

public static String getIpAddr(HttpServletRequest request) {  
        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.getHeader("HTTP_X_FORWARDED_FOR");  
        }  
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)||ip.startsWith("10.")) {  
            ip = request.getRemoteAddr();  
        }  
        return ip;  
    }
