HttpWebRequest：如何识别为浏览器？

问题是如何构建HttpWebRequest因此查询服务器会认为它来自浏览器？

Answer 1

您可以设置User-Agent HTTP请求标头。

 var request = (HttpWebRequest)WebRequest.Create("http://www.google.com"); request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2"; 

或者如果您使用WebClient ：

 using (var client = new WebClient()) { client.Headers[HttpRequestHeader.UserAgent] = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2"; ... }
