[英]Using jsoup to connect to untrusted certificate
我的 Java 应用程序有问题。 我使用 JSOUP 连接到一个以前是 http 而现在移动到 https 的网站。 现在,当我运行该应用程序时,出现以下错误,是否有人能够对此提供帮助?

如果您信任该站点,则可以通过将其设置为 true 来忽略 http 错误:
Document doc = Jsoup.connect("your_url").ignoreHttpErrors(true).get();
并忽略 TSL 验证,设置 validateTLSCertificates(false):
Document doc = Jsoup.connect("your_url").validateTLSCertificates(false).get();
编辑
此答案已过时,因为 JSoup 已弃用并删除了 1.12.1 版中的 validateTLSCertificates 方法
( https://jsoup.org/news/release-1.12.1 )。
