從IOwinContext獲取瀏覽器信息

Question

如何從IOwinContext獲取瀏覽器？

我試圖從我的owin中間件（下面的代碼）旁邊迴應他們的請求。

public async override Task Invoke(IOwinContext context) 
{ 
    var sw = new Stopwatch(); 
    sw.Start(); 
    var user = context.Authentication.User.Identity.IsAuthenticated ? 
     context.Authentication.User.Identity.Name : 
     "anonymous"; 

    _logger.WriteVerbose(
     string.Format("{0} {1} '{2}{3}{4}' @ {5} for {6}", 
     context.Request.Scheme, 
     context.Request.Method, 
     context.Request.PathBase, 
     context.Request.Path, 
     context.Request.QueryString, 
     context.Request.LocalIpAddress, 
     user)); 
    await Next.Invoke(context); 

    _logger.WriteVerbose(
     string.Format("{0} {1} {2}ms - {3}", 
     context.Response.StatusCode, 
     context.Request.Path, 
     sw.ElapsedMilliseconds, 
     context.Request.Browser); //??? 
}

您可以從該請求的用戶代理頭：

context.Request.Headers.Get("User-Agent")
