I have been searching how can I perform the login doing a scrapping of the website with JSOUP but when try to connect to the website I got the next error 我一直在搜索如何使用JSOUP进行网站剪贴以执行登录，但是当尝试连接到网站时出现下一个错误

javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found. javax.net.ssl.SSLHandshakeException：java.security.cert.CertPathValidatorException：找不到证书路径的信任锚。

1 个解决方案

Usually login into a web site requires two steps - 通常，登录网站需要两个步骤-
1. You send a get request to get the page, and you extract from there some values like session ID etc, and the cookies. 1.您发送一个get请求以获取页面，然后从那里提取一些值，例如会话ID等，以及cookie。
2. You send a post request with the values from step 1, and your user name and password. 2.您发送带有第1步中的值以及您的用户名和密码的post请求。
To know which values you need to send, use your browser in the developer mode (by pressing F12) and examine the traffic. 要知道您需要发送哪些值，请在开发人员模式下使用浏览器（按F12键）并检查流量。 If you want to write an android app, change the user agent string to match your browser, since some sites send different pages to different clients. 如果您要编写一个android应用，请更改user agent字符串以匹配您的浏览器，因为某些网站会将不同的页面发送给不同的客户端。 You can see an example here . 您可以在此处查看示例。
