Question

我想使用Java登录我的LMS（学习管理系统）帐户。为此，我编写了这段代码（如下所示），但这是抛出javax.net.ssl.SSLHandshakeException。我已经在this tutorial之后将LMS网站的证书添加到JRE的cacerts文件中，但我仍然得到相同的例外。那么请告诉我如何成功登录我的LMS帐户？

CODE：

import java.util.Map;
import org.jsoup.Connection;
import org.jsoup.Connection.Method;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;


public class A {

    public static void main(String arg[]) throws Exception {

        Connection.Response res = Jsoup.connect("url_of_lms_login_page")
                .data("username", "my_username", "password", "my_password")
                .method(Method.POST)
                .execute();

        Map<String, String> loginCookies = res.cookies();

        Document doc = Jsoup.connect("url_of_home_page_after_login")
                .cookies(loginCookies)
                .get();
    }
}

例外：

javax.net.ssl.SSLHandshakeException（即使在添加证书之后）
