使用Jsoup登录Asp.net表单的Post方法

import org.jsoup.Connection;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

public class JsoupLoginExample {
    public static void main(String[] args) throws Exception {
        // 获取登录页面
        String loginUrl = "http://example.com/login";
        Connection.Response loginPageResponse = Jsoup.connect(loginUrl).method(Connection.Method.GET).execute();
        Document loginPageDoc = loginPageResponse.parse();

        // 解析登录页面，获取登录表单的相关信息
        String loginFormUrl = "http://example.com/login";
        String loginActionUrl = "http://example.com/doLogin";
        String usernameFieldName = "username";
        String passwordFieldName = "password";

        // 构造登录请求参数
        String username = "your_username";
        String password = "your_password";
        String csrfToken = loginPageDoc.select("input[name=__RequestVerificationToken]").val();

        // 发送登录请求
        Connection.Response loginActionResponse = Jsoup.connect(loginActionUrl)
                .cookies(loginPageResponse.cookies())
                .data("__RequestVerificationToken", csrfToken)
                .data(usernameFieldName, username)
                .data(passwordFieldName, password)
                .method(Connection.Method.POST)
                .execute();

        // 处理登录后的响应
        Document loggedInPageDoc = loginActionResponse.parse();
        // TODO: 根据需要进行后续操作
    }
