Asp.Net Core2.0获取客户IP地址，及解决发布到Ubuntu服务器获取不到正确IP解决办法

1、获取客户端IP地址实现方法（扩展类）

 1 using Microsoft.AspNetCore.Http;

 2 using Microsoft.AspNetCore.Mvc.ModelBinding;

 3 using System.Collections.Generic;

 4 using System.Linq;

 5

 6 namespace WebApi.Controllers

 7 {

 8     /// <summary>

 9     /// 扩展类

10     /// </summary>

11     public static class Extension

12     {

13         /// <summary>

14         /// 获取客户Ip

15         /// </summary>

16         /// <param name="context"></param>

17         /// <returns></returns>

18         public static string GetClientUserIp(this HttpContext context)

19         {

20             var ip = context.Request.Headers["X-Forwarded-For"].FirstOrDefault();

21             if (string.IsNullOrEmpty(ip))

22             {

23                 ip = context.Connection.RemoteIpAddress.ToString();

24             }

25             return ip;

26         }

27     }

28 }

调用该方法：

var ip = HttpContext.GetClientUserIp();

2、解决Asp.Net Core2.0发布到Ubuntu后不能正确获取客户IP解决办法

 1         /// <summary>

 2         ///

 3         /// </summary>

 4         /// <param name="app"></param>

 5         /// <param name="env"></param>

 6         /// <param name="loggerFactory"></param>

 7         public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)

 8         {

 9             #region 解决Ubuntu Nginx 代理不能获取IP问题

10             app.UseForwardedHeaders(new ForwardedHeadersOptions

11             {

12                 ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto

13             });

14             #endregion

15         }

本人站点用的是Nginx进行代理，而站点指向是本地Ip,不能正确获得客户的IP,这时就需要通过Nginx获取到的IP传递给站点

Nginx的配置

 1 server {

 2         listen 80;

 3          server_name www.xxx.com;

 4          root /var/www/html;

 5           index index.html index.htm index.nginx-debian.html;

 6

 7         location / {

 8         proxy_pass http://localhost:5000;

 9         proxy_http_version 1.1;

10         proxy_set_header Upgrade $http_upgrade;

11         proxy_set_header Connection keep-alive;

12         proxy_set_header Host $host;

13         proxy_set_header X-Real-IP $remote_addr;

14         proxy_cache_bypass $http_upgrade;

15         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

16     }

17 }

重启Nginx：

sudo service nginx restart;
