HttpWebRequest-已启用伪造Javascript

本文关键字：Javascript 伪造 启用 HttpWebRequest- | 更新日期: 2023-09-27 18:00:55

我正在尝试使用下载c#中的网页

var responseData = "";
var strUrl = this.QuerySelector(item, "a[class='url']").Attributes["href"].Value;
request = (HttpWebRequest)WebRequest.Create(strUrl);
request.Method = "GET";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = 0;
request.CookieContainer = cookies;
request.Timeout = System.Threading.Timeout.Infinite;
request.UserAgent = this.RefreshUserAgent();
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
request.Headers.Add("Accept-Encoding", "gzip,deflate,sdch");
request.KeepAlive = true;
request.AllowAutoRedirect = false;
request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
response = (HttpWebResponse)request.GetResponse();
response.Cookies = request.CookieContainer.GetCookies(request.RequestUri);
var encoding = new System.Text.UTF8Encoding();
var responseReader = new StreamReader(response.GetResponseStream(), encoding, true);
responseData = responseReader.ReadToEnd();
response.Close();
responseReader.Close();

但该网站一直给我相同的代码，使JavaScript能够继续。我已经用Fiddler检查了数据-它只是再次导航到自己，但我无法通过这个消息：

Before you can move on - please enable JavaScript.

网站是Manta.com，这是我的示例页面。有什么想法吗。。

HttpWebRequest-已启用伪造Javascript

这是正确的。HttpWebRequest只是执行HTTP请求。它不支持JavaScript。如果你想要这种行为，试着使用WebBrowser控件或类似Awesomium的东西。

您可以尝试伪造UserAgent请求标头：

request.UserAgent = "Mozilla/5.0 (Windows NT 6.3; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0";
