Owin：异常：System.ObjectDisposedException：无法访问已处置的对象。对象名称：“ System.Net.HttpListenerRequest”

Question

我下面有很多下面的日志，有人知道这的根本原因吗？这是否与以下代码相关：

// Gets the client IP when hosted in IIS, where HttpContext.Current is not null.
if (httpRequest != null)
    return httpRequest.UserHostAddress;

// Gets the client IP when hosted in Owin, where there is no HttpContext.Current by default.
if (!request.Properties.ContainsKey("MS_OwinContext")) return null;

var context = request.Properties["MS_OwinContext"] as OwinContext;
return context?.Request.RemoteIpAddress;

日志：
