我正在嘗試創建一個java程序，該程序對achievo實例執行登錄。我正在嘗試使用Screen Scraping。瀏覽器不支持幀
我管理使用下面的代碼登錄：
@Test
public void testLogin() throws Exception {
HashMap<String, String> data = new HashMap<String, String>();
data.put("auth_user", "user");
data.put("auth_pw", "password");
doSubmit("https://someurl.com/achievo/index.php", data);
}
private void doSubmit(String url, HashMap<String, String> data) throws Exception {
URL siteUrl = new URL(url);
HttpsURLConnection conn = (HttpsURLConnection) siteUrl.openConnection();
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.setDoInput(true);
//conn.setRequestProperty("User-agent", "spider");
//conn.setRequestProperty("User-agent", "Opera/9.80 (X11; Linux i686; U; en) Presto/2.7.62 Version/11.01");
conn.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; .NET CLR 1.2.30703)");
DataOutputStream out = new DataOutputStream(conn.getOutputStream());
Set<String> keys = data.keySet();
Iterator<String> keyIter = keys.iterator();
StringBuilder content = new StringBuilder("");
for(int i=0; keyIter.hasNext(); i++) {
Object key = keyIter.next();
if(i!=0) {
content.append("&");
}
content.append(key + "=" + URLEncoder.encode(data.get(key), "UTF-8"));
}
System.out.println(content.toString());
out.writeBytes(content.toString());
out.flush();
out.close();
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line = "";
while((line=in.readLine())!=null) {
System.out.println(line);
}
in.close();
}
然而，當大展成功登錄項，我重定向到主頁，它說：
<head>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
<title>Achievo</title>

</frameset>
<noframes>
<body bgcolor="#CCCCCC" text="#000000">

很顯然，我得到您的瀏覽器不支持框架，但這是運行Achievo所必需的。
我試圖直接訪問dispatch.php框架，因爲這是我可能想要的，但是，它報告我的會話已過期，而且我需要重新登錄。
有沒有辦法僞造一個框架？或者以某種方式保持連接，更改網址，並嘗試獲取dispatch.php框架？
使用的HtmlUnit，我也做了以下內容：
WebClient webClient = new WebClient(BrowserVersion.FIREFOX_3);
HtmlPage page = webClient.getPage("https://someurl.com/index.php");
System.out.println(page.asXml());
List<HtmlForm> forms = page.getForms();
assertTrue(forms != null && !forms.isEmpty());
HtmlForm form = forms.get(0);
HtmlSubmitInput submit = form.getInputByName("login");
HtmlInput inputUsername = form.getInputByName("auth_user");
HtmlInput inputPw = form.getInputByName("auth_pw");
inputUsername.setValueAttribute("foo");
inputPw.setValueAttribute("bar");
HtmlPage page2 = submit.click();
CookieManager cookieManager = webClient.getCookieManager();
Set<Cookie> cookies = cookieManager.getCookies();
System.out.println("Is cookie " + cookieManager.isCookiesEnabled());
for(Cookie cookie : cookies) {
System.out.println(cookie.toString());
}
System.out.println(page2.asXml());
webClient.closeAllWindows();
這裏我得到的形式，我提交它，我找回了同樣的信息。當我也打印出來時，我可以看到我有一個cookie。現在的問題是，我如何繼續使用登錄的Cookie獲取dispatch.php框架？
當您嘗試訪問displatch.php時，您需要傳遞會話中的cookie以及[引薦標題]（http://en.wikipedia.org/wiki/HTTP_referrer）。我強烈建議您使用Apache HTTPClient，因爲它會自動執行cookie管理，並且使訪問任何http資源變得更簡單。 – Augusto
