package tr.demo;


import jakarta.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GetIPService {

//方式一
    @GetMapping("/getIp")
    public String getIP(HttpServletRequest request){
        String remoteAddr = request.getRemoteAddr();
        String remoteHost = request.getRemoteHost();
        System.out.println("remoteAddr="+remoteAddr);
        System.out.println("remoteHost="+remoteHost);
        return remoteAddr;
    }


//方式二
    @GetMapping("getIp002")
    public String getIpAddress(HttpServletRequest request) {
        String ipAddress = request.getHeader("X-Forwarded-For");
        if (ipAddress == null || ipAddress.isEmpty() || "unknown".equalsIgnoreCase(ipAddress)) {
            ipAddress = request.getHeader("Proxy-Client-IP");
        }
