[教程] Discuz! X3.5 针对常见CDN/WAF/负载均衡，如何获取真实IP？

观前提示：修改Discuz不是获取真实IP的最佳方法
如果您有能力，建议了解Apache mod_remoteip、Nginx ngx_http_realip_module 或其他同类功能
在服务器端配置可以让你的服务器访问日志也能收集到正确的IP

1. $_config['security']['onlyremoteaddr'] = 1;

1. // -------------------------  CONFIG IPGETTER  -------------------------- //
   
2. $_config['ipgetter']['setting'] = '';
   
3. $_config['ipgetter']['header']['header'] = 'HTTP_X_FORWARDED_FOR';

1. $_config['ipgetter']['setting'] = '';

1. $_config['ipgetter']['setting'] = 'header';

1. $_config['ipgetter']['header']['header'] = 'HTTP_X_FORWARDED_FOR';

1. $_config['ipgetter']['header']['header'] = 'HTTP_CF_CONNECTING_IP';

1. $_config['ipgetter']['header']['header'] = 'HTTP_ALI_CDN_REAL_IP';

1. $_config['ipgetter']['header']['header'] = 'HTTP_X_REAL_IP';

1. $_config['ipgetter']['header']['header'] = 'HTTP_X_CLIENT_IP';

华为云cdn 要获取真实IP 需要去开工单 单独域名每个配置 已经配置好了 也获取到了 特此说明

1. $_config['ipgetter']['header']['header'] = 'HTTP_X_REAL_IP';

1. $_config['ipgetter']['header']['header'] = 'HTTP_FASTLY_CLIENT_IP';

1. $_config['ipgetter']['header']['header'] = 'HTTP_X_AZURE_CLIENTIP';

1. define('UC_ONLYREMOTEADDR', 1);
   
2. define('UC_IPGETTER', 'header');
   
3. define('UC_IPGETTER_HEADER', serialize(array('header' => 'HTTP_X_FORWARDED_FOR')));
