asp.net core使用jexus部署在linux无法正确获取远程ip的解决

时间:2017-08-11来源:linux网站 作者:晓晨Master
asp.net core程序部署在centos7(下面的解决方案,其他系统都能使用,这里只是我自己部署在centos7),使用服务器jexus进行部署,AppHost模式。
因为请求是由jexus进行了转发的,所以asp.net zero获取的ip永远都是127.0.0.1.。
 
解决方案:
使用由Jexus作者宇内流云提供的JwsIntegration替换IISIntegration,它改变默认从请求头获取ip的规则,改为由 “X-Original-For”获取远程ip(经测试 使用"X-Real-IP"也能获取)。
JwsIntegration.cs:
/// <summary>
/// 用于处理客户IP地址、端口的HostBuilder中间件
/// </summary>
public static class WebHostBuilderJexusExtensions
{
/// <summary>
/// 启用JexusIntegration中间件
/// </summary>
/// <param name="hostBuilder"></param>
/// <returns></returns>
public static IWebHostBuilder UseJexusIntegration(this IWebHostBuilder hostBuilder)
{
if (hostBuilder == null)
{
throw new ArgumentNullException(nameof(hostBuilder));
}
// 检查是否已经加载过了
if (hostBuilder.GetSetting(nameof(UseJexusIntegration)) != null)
{
return hostBuilder;
}
// 设置已加载标记,防止重复加载
hostBuilder.UseSetting(nameof(UseJexusIntegration), true.ToString());
// 添加configure处理
hostBuilder.ConfigureServices(services =>
{
services.AddSingleton<IStartupFilter>(new JwsSetupFilter());
});
return hostBuilder;
}
}
class JwsSetupFilter : IStartupFilter
{
public Action<IApplicationBuilder> Configure(Action<IApplicationBuilder> next)
{
return app =>
{
app.UseMiddleware<JexusMiddleware>();
next(app);
};
}
}
class JexusMiddleware
{
readonly RequestDelegate _next;
public JexusMiddleware(RequestDelegate next, ILoggerFactory loggerFactory, IOptions<IISOptions> options)
{
_next = next;
}
public async Task Invoke(HttpContext httpContext)
{
var headers = httpContext.Request.Headers;
try
{
if (headers != null && headers.ContainsKey("X-Original-For"))
{
var ipaddAdndPort = headers["X-Original-For"].ToArray()[0];
var dot = ipaddAdndPort.IndexOf(":", StringComparison.Ordinal);
var ip = ipaddAdndPort;
var port = 0;
if (dot > 0)
{
ip = ipaddAdndPort.Substring(0, dot);
port = int.Parse(ipaddAdndPort.Substring(dot + 1));
}
httpContext.Connection.RemoteIpAddress = System.Net.IPAddress.Parse(ip);
if (port != 0) httpContext.Connection.RemotePort = port;
}
}
finally
{
await _next(httpContext);
}
}
}
