如何在Microsoft Azure中部署的Web服务中获取源IP

Question

我有一个部署在Microsoft Azure的java REST Web服务。 我想记录调用者的IP地址，无论谁使用我的API。 问题是，如果我只是从remoteaddress获取IP，那么它将提供Azure的默认IP。 如何捕获调用者的原始IP。

正如@Joey在评论中提到的那样，您可以按照doc在您的网络应用中获取客户端的IP地址。

我在我的azure spring-boot网络应用程序中测试过，请参阅我的示例代码：

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import java.net.InetAddress;
import java.net.UnknownHostException;

@RestController
public class HelloController {
@RequestMapping("/getip")
    public String getIp(HttpServletRequest request) {
        return getIpAddr(request);
    }


    public static String getIpAddr(HttpServletRequest request) {
        String ipAddress = null;
        try {
            ipAddress = request.getHeader("x-forwarded-for");
            if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
                ipAddress = request.getHeader("Proxy-Client-IP");
            }
            if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
                ipAddress = request.getHeader("WL-Proxy-Client-IP");
            }
            if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
                ipAddress = request.getRemoteAddr();
                if (ipAddress.equals("127.0.0.1")) {

                    InetAddress inet = null;
                    try {
                        inet = InetAddress.getLocalHost();
                    } catch (UnknownHostException e) {
                        e.printStackTrace();
                    }
                    ipAddress = inet.getHostAddress();
                }
            }

            if (ipAddress != null && ipAddress.length() > 15) { // "***.***.***.***".length()
                // = 15
                if (ipAddress.indexOf(",") > 0) {
                    ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));
                }
            }
        } catch (Exception e) {
            ipAddress = "";
        }
        // ipAddress = this.getRequest().getRemoteAddr();

        return ipAddress;
    }
}

希望它对你有所帮助。
