回源服務器地址為IP格式

配置

獲取請求頭方法

以PHP為例。

<?
print_r($_SERVER);
?>

以SpringBoot（Java）為例。

@RestController
public class TestController {
    @GetMapping("/test")
    public String test(HttpServletRequest request) {
        Enumeration headerNames = request.getHeaderNames();
        while (headerNames.hasMoreElements()) {
            String headerName = headerNames.nextElement();
            String headerValue = request.getHeader(headerName);
            System.out.println(headerName + ":" + headerValue);
        }
        return "success";
    }
}

1. 源服務器未使用代理轉發該端口的請求(如沒有使用nginx轉發端口請求)。
   http協議 請求的字段

   array(10) {
    ["request_method"]=>
    string(3) "GET"
    ["request_uri"]=>
    string(1) "/"
    ["path_info"]=>
    string(1) "/"
    ["request_time"]=>
    int(1613802357)
    ["request_time_float"]=>
    float(1613802357.2114)
    ["server_protocol"]=>
    string(8) "HTTP/1.1"
    ["server_port"]=>
    int(4501)
    ["remote_port"]=>
    int(31205)
    ["remote_addr"]=>
    string(14) "**購買的高防IP**"
    ["master_time"]=>
    int(1613802357)
   }

   header中的 字段

   array(11) {
   ["host"]=>
   string(21) "添加的域名"
   ["x-real-ip"]=>
   string(13) "真實的訪客IP"
   ["x-forwarded-host"]=>
   string(15) "訪問域名"
   ["x-forwarded-scheme"]=>
   string(4) "http"
   ["x-forwarded-for"]=>
   string(13) "真實的訪客IP"
   ["user-agent"]=>
   string(115) "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36"
   ["connection"]=>
   string(10) "keep-alive"
   ["accept"]=>
   string(50) "image/avif,image/webp,image/apng,image/*,*/*;q=0.8"
   ["referer"]=>
   string(29) "..."
   ["accept-encoding"]=>
   string(13) "gzip, deflate"
   ["accept-language"]=>
   string(14) "zh-CN,zh;q=0.9"
   }

2. 源服務器使用代理服務轉發端口的請求（如使用nginx轉發）。
   nginx 配置參考

   server {
    listen       8481;#如源機接收請求的端口設置為8481端口，而8481端口又轉發請求
    server_name  localhost;
    root     /home/www/;
    index  index.php;
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ {
        expires 100d;
    }
    location ~ .*\.(js|css)?$ {
        expires 30d;
    }
    location ~ \.php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_param  PATH_INFO  $fastcgi_path_info;
        fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
        include        fastcgi_params;
    }
   }
