1、获取客户端IP地址实现方法（扩展类）
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc.ModelBinding;
using System.Collections.Generic;
using System.Linq; namespace WebApi.Controllers
{
/// <summary>
/// 扩展类
/// </summary>
public static class Extension
{
/// <summary>
/// 获取客户Ip
/// </summary>
/// <param name="context"></param>
/// <returns></returns>
public static string GetClientUserIp(this HttpContext context)
{
var ip = context.Request.Headers["X-Forwarded-For"].FirstOrDefault();
if (string.IsNullOrEmpty(ip))
{
ip = context.Connection.RemoteIpAddress.ToString();
}
return ip;
}
}
}
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
/// <summary>
///
/// </summary>
/// <param name="app"></param>
/// <param name="env"></param>
/// <param name="loggerFactory"></param>
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
#region 解决Ubuntu Nginx 代理不能获取IP问题
app.UseForwardedHeaders(new ForwardedHeadersOptions
{
ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
});
#endregion
}
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
server {
listen ;
server_name www.xxx.com;
root /var/www/html;
index index.html index.htm index.nginx-debian.html;
location / {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
重启Nginx：
sudo service nginx restart;
