我想使用HTTPWEBREQUEST为以下页面获取HTML：
http://inkdispatch.com/brother
目前我正在使用：
public static string getHTML(string url)
{
string responseData = "";
try
{
// System.Threading.Thread.Sleep(1000 * 1);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Accept = "application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*";
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E)";
request.Timeout = 60000;
request.AllowAutoRedirect = false;
request.Method = "GET";
request.Referer = "inkdispatch.com";
request.CookieContainer = yummycookies;
request.KeepAlive = true;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
StreamReader myStreamReader = new StreamReader(responseStream);
responseData = myStreamReader.ReadToEnd();
}
foreach (Cookie cook in response.Cookies)
{
yummycookies.Add(cook);
}
response.Close();
}
catch (Exception e)
{
responseData = "An error occurred: " + e.Message;
}
return responseData;
}
但是我没有看到任何我得到回应而没有错误只是说，移动渗透，当我在浏览器中放置相同的链接时它工作。该链接附有一个令牌，但我确实从主页面获得了这一点，但仍然可以提供任何帮助。
更新
我刚刚设置：
request.AllowAutoRedirect = true;
但我收到错误：
Too many automatic redirections were attempted.
at System.Net.HttpWebRequest.GetResponse()
at inkdispatchcomScraper.Program.getHTML(String url)
我有小提琴打开，显示它一次又一次地击中链接：

另一个更新
我已经看到当我在IE中打开它时，它使用重定向到/兄弟但是在代码的情况下它会获得另一个ZENID蚂蚁前进到那个并且这种情况一直在发生。
答案 0 :(得分：4)
设置request.AllowAutoRedirect = true;
修改
对于第二个问题，请声明yummycookies，如下所示。
public static string getHTML(string url)
{
CookieContainer yummycookies = new CookieContainer();
...
}
答案 1 :(得分：0)
当我尝试测试你的代码时，它失败了，但是另一个测试我发现了以下错误“尝试了太多的自动重定向。”
在更新代码并再次测试时，它在您提供的网址上运行良好，html正确获取。代码在这里。
public static string GetHtml2(string urlAddr)
{
if (urlAddr == null || string.IsNullOrEmpty(urlAddr))
{
throw new ArgumentNullException("urlAddr");
}
else
{
string result;
//1.Create the request object
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlAddr);
//request.AllowAutoRedirect = true;
//request.MaximumAutomaticRedirections = 200;
request.Proxy = null;
request.UseDefaultCredentials = true;
//2.Add the container with the active
CookieContainer cc = new CookieContainer();
//3.Must assing a cookie container for the request to pull the cookies
request.CookieContainer = cc;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream()))
{
result = sr.ReadToEnd();
//Close and clean up the StreamReader
sr.Close();
}
return result;
}
}
希望这没关系。
