I am trying what I thought was a simple operation.    I am not able to send any request with webrequest    get response.   I am able to get a quick response with a browser.   I then used wireshark and it shows that there is not even a request going out.

  var request = (HttpWebRequest)WebRequest.Create(@"http://10.184.44.97:8085/logs/");
            request.Accept = "text/html";
            request.Method = "GET";
            request.ContentType = "text/html";
        
            Stopwatch sw = new Stopwatch();
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            sw.Stop();
                Console.WriteLine("{0} response time = {1}");

推荐答案

你好霍华德，

有趣的一个；没有上面的第一手经验，因为您上面的代码看起来不错.  我假设没有引发异常，并且您看到了控制台写指令行吗?

Interesting one; no first hand experience of this one as the code you have above looks fine.  I am assuming no exceptions are thrown and that you see the console writeline?

那么我的猜测是与端口相关的东西可以阻止这种情况的发生.您是否尝试过80端口?  如果可以，那么我将集中精力确保8085已打开.  我的猜测是有一些低水平的东西正在阻止它(防火墙).

My guess then would be something port related blocking this from happening.  Have you tried port 80?  If so and it works then I would concentrate on making sure 8085 is open.  My guess is something low level is blocking this (firewall).
