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;
        }
    }
}

 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
        }
