java - 登录并从网页 Jsoup 提取数据

Question

所以我尝试通过此方法登录到网站，然后从网站“http://www.website.com”内的其他网页中获取该元素

public class TicketingJsoup {

public static void main (String [] args) throws IOException{
       try {
            String url = "www.website.com";
            Connection.Response response = Jsoup.connect(url).method(Connection.Method.GET).execute();

            response = Jsoup.connect(url)
                    .cookies(response.cookies())
                    .data("Action", "Login")
                    .data("User", "myuser")
                    .data("Password", "mypass")
                    .method(Connection.Method.POST)
                    .followRedirects(true)
                    .execute();

            Document document = response.parse();
            System.out.println(document);

            Map<String, String> loginCookies = response.cookies();


               Elements ticketNumber = doc.select("body > div.MainBox.ARIARoleMain.UseArticleColors > div.Headline > h1");
              System.out.println(ticketNumber);   
              System.out.println("TEST");

        } catch (IOException e) {
            e.printStackTrace();
        }
}

}

堆栈跟踪

我做错了什么？我正在绞尽脑汁试图弄清楚如何做到这一点，我也尝试了很多其他事情，但它们导致了死胡同。我认为这是最好的方法，但如果我错了，请告诉我更好的方法。

谢谢。

试试这个代码:

   try {
        String url = "www.website.com";
        Connection.Response response = Jsoup.connect(url).method(Connection.Method.GET).execute();

        response = Jsoup.connect(url)
                .cookies(response.cookies())
                .data("Action", "Login")
                .data("User", "your_login")
                .data("Password", "your_password")
                .method(Connection.Method.POST)
                .followRedirects(true)
                .execute();

        Document document = response.parse();
        System.out.println(document);

    } catch (IOException e) {
        e.printStackTrace();
    }
