java - 找不到与 www.billiving.com 匹配的主题备用 DNS 名称。为什么会这样，如何解决？

Question

我有 www.billiving.com API 的集成测试套件。当该 API 调用端点应为 https://www.billiving.com .

我的测试套件在 Windows 上完美运行。然而，当它移动到 ubuntu 14.x 时，它会失败并出现以下异常。 [1]

所以我编写了此 [2] 代码以在测试套件之外对其进行测试。仍然失败并出现相同的异常。

所以我尝试将 billiving.com 证书导入 JKS，但仍然失败并出现同样的异常。

我知道作为一种解决方案，我们可以覆盖 Verifier 类中的验证方法并返回 true。但我需要适当的解决方案，因为这会导致安全问题。

1) 为什么这个错误以及为什么它只在 linux 上。

2) 我们怎样才能用合适的方法解决这个问题

[2] 示例代码:

import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

public class Application {

    public static void main(String[] args) {

        URL url;
        try {
            url = new URL(args[0]);

        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setInstanceFollowRedirects(false);
        connection.setRequestMethod("GET");

        if (connection.getResponseCode() >= 400) {
            System.out.println("ERROR "+ connection.getResponseCode());
        } else {
            System.out.println("Success");
        }

        System.out.println("Connection Crated");



        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }


}

使用上面代码的命令:

java Application https://www.billiving.com

Answer 1

该站点的真实证书具有正确的主机名。但是只有在使用 SNI ( Server Name Indication ) 时才会获得此证书。较旧的 Java 版本不支持 SNI(应该从 Java 7 开始支持)，因此您可能需要升级您的未指定版本。
