问题：Jsoup登录后携带Cookie访问子页面无法维持登录状态

问题描述

登录成功后可正常获取有效Cookie，但携带这些Cookie访问网站子页面（如https://www.valueresearchonline.com/funds/26123/motilal-oswal-flexi-cap-fund-regular-plan/#fund-portfolio）时，无法维持登录状态，无法查看仅登录可见的“Top Holdings”板块。

有效步骤：获取Cookie

Java登录代码

Connection.Response login2 = Jsoup.connect("https://www.valueresearchonline.com/login/?")
            .timeout(15000)
            .userAgent("Mozilla")
            .data("username", "valid_email")
            .data("password", "valid_password")
            .method(Connection.Method.POST)
            .execute();

System.out.println(login2.statusCode());
System.out.println(login2.cookies());
doc = login2.parse();

System.out.println(doc.body().text().indexOf("My Favourite Stories"));
System.out.println(doc.body().text().indexOf("Logout"));

String sessionId2 = login2.cookie("PHPSESSID");

问题原因与解决方案

核心原因

请求目标错误：你访问的带#fund-portfolio的URL是前端锚点，实际登录后可见的“Top Holdings”数据是通过AJAX请求https://www.valueresearchonline.com/fund-details/26123/?tab=fund-portfolio获取的，直接请求原页面不会触发该接口调用。
请求头缺失：服务器需要通过X-Requested-With: XMLHttpRequest、Accept: application/json, text/javascript, */*; q=0.01等头识别AJAX请求，否则不会返回登录后专属内容。
Cookie传递问题：你在POST请求中同时调用.cookie()和.cookies()，后者会覆盖前者，可能导致Cookie不完整；且仅传递PHPSESSID不够，其他Cookie（如currency、magnitude）也参与状态验证。
请求方法错误：实际数据接口是GET请求，你用POST不符合服务器预期。

修正后的代码

1. 登录获取完整Cookie

Connection.Response loginResponse = Jsoup.connect("https://www.valueresearchonline.com/login/?")
        .timeout(15000)
        // 使用完整UA，避免服务器拦截
        .userAgent("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36")
        .data("username", "valid_email")
        .data("password", "valid_password")
        .method(Connection.Method.POST)
        .execute();

// 验证登录状态
System.out.println("登录状态码：" + loginResponse.statusCode());
System.out.println("是否登录成功：" + loginResponse.parse().body().text().contains("Logout"));

2. 请求实际数据接口

Connection.Response portfolioResponse = Jsoup.connect("https://www.valueresearchonline.com/fund-details/26123/?tab=fund-portfolio")
        .timeout(15000)
        .userAgent("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36")
        .cookies(loginResponse.cookies()) // 传递所有登录返回的Cookie
        .header("Accept", "application/json, text/javascript, */*; q=0.01")
        .header("X-Requested-With", "XMLHttpRequest")
        .header("Referer", "https://www.valueresearchonline.com/funds/26123/motilal-oswal-flexi-cap-fund-regular-plan/")
        .method(Connection.Method.GET)
        .execute();

// 输出返回内容，包含Top Holdings数据
System.out.println("接口状态码：" + portfolioResponse.statusCode());
System.out.println("返回数据：" + portfolioResponse.body());

注意事项

不要简化User-Agent，使用浏览器抓包的完整UA更稳妥；
必须传递所有登录返回的Cookie，不要只提取单个PHPSESSID；
模拟浏览器真实请求流程，先访问子页面主URL，再请求数据接口，可进一步降低被拦截概率。
