createSocket、connect和connectionTimeout中的HTTPS问题

Question

当我创建这样的SSL套接字时：

sslSocket = (SSLSocket) socketFactory.createSocket(host, port);

一切都正常。socketFactory是SSLSocketFactory.getDefault()。但是，我想设置连接超时。因此，我将上面的代码更改为以下代码：

sslSocket = (SSLSocket) socketFactory.createSocket();
sslSocket.connect(new InetSocketAddress(host, port), connectionTimeout);

但我得到了以下例外：

Exception in thread "main" jodd.http.HttpException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target;

原因例外：

sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

在调试时，我注意到在第一种情况下，代码从请求的站点获取所有有效的证书。在第二种情况下，这些证书丢失了，因此出现了错误。

我还需要在我的2行更改中添加什么，才能使它像第一个一线版本一样工作呢？

完全STACKTRACE

Answer 1

这是答案。根据我的经验，这：

sslSocket = (SSLSocket) socketFactory.createSocket();
sslSocket.connect(new InetSocketAddress(host, port), connectionTimeout);

不起作用(尽管你可以在任何地方看到这个解决方案！)。相反，我执行了以下操作:创建一个常规套接字，然后将其包装为SSL套接字：

Socket sock = new Socket();
sock.connect(new InetSocketAddress(host, port), connectionTimeout);
sslSocket = (SSLSocket)socketFactory.createSocket(sock, host, port, true);

其中socketFactory是一个SSLSocketFactory实例。
