我想登录特定的网站，但如果要这样做，我需要从网络上获取一些隐藏的数据。在接下来的所有会话中，它都不同，所以我认为我必须保持会话活着。要检查我是否登录我想去这个特定网站的另一个页面（你必须登录才能看到它）

好的，所以我得到了回复，我得到了我的信息作为 LOGIN，以及 HIDDEN_NAME 和 HIDDEN_VALUE 中的 2 个，然后我想用我的电子邮件通过邮件登录表单，并通过这些数据登录。

这就是我这样做的方式，但它不起作用：

我使用 Jsoup 而不是 HttpClient API

我创建了获取登录数据的方法

public Connection.Response getLoginData() {
        Connection.Response res = null;
        try {
            String html;
            int length, counter;

            res = Jsoup
                    .connect("https://bannersbroker.com//user/login?event=doLogin")
                    .execute();

            html = res.parse().toString();
            length = html.length();
            counter = 0;

            for (int i = 0; i < length; i++) {
                if (html.startsWith("document.write", i)) {
                    name[counter] = html.substring(i + 41, i + 144);
                    value[counter] = "Login";
                    counter++;
                }
                if (html.startsWith("hidden", i)) {
                    name[counter] = html.substring(i + 13, i + 81);
                    value[counter] = html.substring(i + 90, i + 123);
                    counter++;
                }
            }

        } catch (IOException ioe) {
        } catch (NullPointerException ioe) {
            JOptionPane.showMessageDialog(RunFrame.getInstance(),
                    "Could not open connection to Banners Broker!",
                    "Error",
                    JOptionPane.ERROR_MESSAGE);
        }
        return res;
    }

然后我用另一种方法登录

public Connection.Response doLogin(Connection.Response res, String email, String pass) {
        Connection.Response res2 = null;
        try {
            res2 = Jsoup
                    .connect("https://bannersbroker.com//user/login?event=doLogin")
                    .cookies(res.cookies())
                    .data("email", email)
                    .data("pass", pass)
                    .data(name[0], value[0])
                    .data(name[1], value[1])
                    .data(name[2], value[2])
                    .method(Connection.Method.POST)
                    .execute();

        } catch (IOException ioe) {
        } catch (IllegalArgumentException ioe) {
            JOptionPane.showMessageDialog(RunFrame.getInstance(),
                    "Could not open connection to Banners Broker!",
                    "Error",
                    JOptionPane.ERROR_MESSAGE);
        } catch (NullPointerException ioe) {
            JOptionPane.showMessageDialog(RunFrame.getInstance(),
                    "Could not open connection to Banners Broker!",
                    "Error",
                    JOptionPane.ERROR_MESSAGE);
        }
        return res2;
    }

我在我的班级的构造函数中调用方法并从一个发送到另一个响应。当我登录时，我从方法处理响应，doLogin() 这就是我解析数据的方式

doc = Jsoup
                    .connect(pageAddres)
                    .cookie("PHPSESSID", res.cookie("PHPSESSID"))
                    .get();
