在我的C#应用​​程序中,我得到了以下代码:

private void button1_Click(object sender, EventArgs e)
{
    string uri = urlTextBox.Text;

    Uri myURL;

    if (!Uri.TryCreate(uri, UriKind.Absolute, out myURL))
        return;

    WebRequest request = WebRequest.Create(myURL);
    request.Method = "GET";
    using (WebResponse response = request.GetResponse())
    {
        using (Stream stream = response.GetResponseStream())
        {
            using(StreamReader sr = new StreamReader(stream))
            {
                responseTextBox.Text = sr.ReadToEnd();
            }
        }
    }

}

但是当我点击按钮时,它会返回以下文字:

<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Login Timed Out</title>
<link rel=stylesheet type="text/css" href="../../shared/css/ilearn_base.css">
<script>
function redirectToTop(reloginLoc) {
   if (opener != null && opener != self) {
      opener.top.location = reloginLoc;
      window.close();
   }

   else if (top != self) {
      top.location = reloginLoc;
   }

   else {
      location = reloginLoc;
   }
}
</script>

</noscript>

</head>
<body onLoad="redirectToTop('../../learner/jsp/relogin_site.jsp')">

</body>
</html>

我无法理解的是为什么它会说:“Your browser does not support JavaScript. Please turn on JavaScript to use the features of this web page.”,因为我在当前浏览器和IE中激活了JavaScript。

在我的互联网浏览器中,页面看起来不同,执行了脚本,我想知道如何在C#浏览器中激活javascript以获得完整的响应。

您收到了完整的回复。

如果您的浏览器不支持javascript,则会包含noscript标记。对于此页面,服务器可能始终在响应中包含此内容 - 这并不一定意味着您的浏览器不支持javascript。
