Question

我想在

中获取HTML输出

但我总是得到

HTTPWEBRESPONSE远程服务器返回错误：（403）Forbidden

我正在使用HttpWebResponse

protected string GetHtmlStringA(string url)
    {
        string sHtml = "";
        HttpWebRequest request;
        HttpWebResponse response = null;
        Stream stream = null;
        request = (HttpWebRequest)WebRequest.Create(url);
        response = (HttpWebResponse)request.GetResponse();
        stream = response.GetResponseStream();
        StreamReader sr = new StreamReader(stream, System.Text.Encoding.Default);
        sHtml = sr.ReadToEnd();
        if (stream != null) stream.Close();
        if (response != null) response.Close();
        return sHtml;
    }

我也尝试使用UserAgent，但它是相同的

req.request=
                    "Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.0.13) Gecko/2009073022 Firefox/3.0.13";

我在论坛或互联网上找不到任何解决方案

Answer 1

您似乎还需要发送Accept标头。使用以下标头发送请求将起作用：

request.UserAgent = "Foo";
request.Accept = "*/*";

Answer 2

您需要使用Web请求传递身份验证凭据：

request.Credentials = new NetworkCredentials("username", "password");

Answer 3

确保正确设置了凭据。

request.Credentials = CredentialCache.DefaultCredentials;

// if we have a proxy set its creds as well
if( request.Proxy != null )
{
   request.Proxy.Credentials = CredentialCache.DefaultCredentials;
}

如果您需要特定凭据，可以通过这种方式创建

request.Credentials = new NetworkCredentials("username", "password");

Answer 4

对我而言，就像他们不希望你屏蔽他们的内容一样。

你可以尝试用fiddler查看请求/响应，看看发生了什么。
