asp.net 对象已移动

Question

String parameters = "__VIEWSTATE=" + "__EVENTTARGET="
                + "__EVENTARGUMENT=" + "&ctl00$tbUsername="
                + URLEncoder.encode("name", "UTF-8") + "&ctl00$tbPwd="
                + URLEncoder.encode("pssw", "UTF-8")
                + "&ctl00$chkRememberLogin=" + URLEncoder.encode("0", "UTF-8")
                + "&ctl00$cmdLogin=" + URLEncoder.encode("Login", "UTF-8");
    URL url;
    HttpURLConnection connection = null;
    try {
        url = new URL("www.website.com/Login.aspx");
        connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type",
                "text/html; charset=utf-8");
        connection.setRequestProperty("Content-Length",
                "" + Integer.toString(parameters.getBytes().length));
//trying everything..
        connection.setDefaultUseCaches(true);
        connection.setUseCaches(true);

        connection.setUseCaches(true);
        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setAllowUserInteraction(true);
        connection.setInstanceFollowRedirects(true);
        HttpURLConnection.setFollowRedirects(true);

        DataOutputStream wr = new DataOutputStream(
                connection.getOutputStream());
        wr.writeBytes(parameters);
        wr.flush();
        wr.close();
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (connection != null) {
            connection.disconnect();
        }

    }
}

这是一个 HTML 表单

<form id="LoginForm" name="LoginForm" method="post" action="Login.aspx?__ufps=747201&loggedout">
<input type="hidden" name="__VIEWSTATE" value="/wEXAQUDX19QD2QPBirKUk9SFs6IZg==">
<input type="hidden" name="__EVENTTARGET" value="">
<input type="hidden" name="__EVENTARGUMENT" value="">
<script language=javascript><!--
function __doPostBack(target, argument){
  var theform = document.LoginForm
  theform.__EVENTTARGET.value = target
  theform.__EVENTARGUMENT.value = argument
  theform.submit()
}
// -->
</script>

<div nowrap><b>Username:</b></div><input name="ctl00$tbUsername" /><br>
<b>Password:</b><br>
<input name="ctl00$tbPwd" type="password"/><br>
<input type="checkbox" name="ctl00$chkRememberLogin" value="0" checked>Remember Me<br>
<input name="ctl00$cmdLogin" type="submit" value="Login"/>&nbsp;
                        <input name="ctl00$cmdForgetMe" type="submit" value="Forget Me"/>
</form>

回复消息是：“对象移至此处”。 #%^#%^?!有人可以解释一下可能出了什么问题吗... WireShark 显示来自客户端和浏览器的相同帖子

请求请知道的人帮帮忙..

据我了解，您尝试通过帖子发送名称和密码，然后您会收到一条重定向消息！从告诉您要阅读不同位置的网页上。

这是因为

1. 您尝试了不安全的页面，而服务器将您重定向到安全的 SSL。
2. 发布后，服务器会处理数据并响应并重定向到新页面。
