我正在尝试创建一个将登录到本地网站的 java 应用程序。问题是“线程“主”javax.net.ssl.SSLHandshakeException 中的异常：PKIX 路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效证书路径”以及登录的事实页面需要通过我可以检查的警报框登录（或不知道如何）
我建立连接的java类是：

//make sure cookies are on
CookieHandler.setDefault(new CookieManager());
//send a GET request sp that we know the form's data
String page = http.GetPageContent(url);
String postParam = http.getFormParams(page, "admin", "admin123");
//Contruct the POST content and send a POST request
http.sendPost(url, postParam);
//When connection is established reply with a result

System.out.println(result);

页面如下所示：
正如您所看到的，它只是 HTTP，所以我认为这可能是一个问题，因为我在这里什至没有证书。
帮助将不胜感激！！！提前致谢！
