用 httpClient 连接 https 服务端，不校验证书的 host

用 httpClient 连接 https 服务，如果证书与 host 不匹配，就会报：Certificate for <124.xxx.xxx.xxx> doesn't match any of the subject alternative names

可以通过在创建 SSLConnectionSocketFactory 时增加一个参数，禁用这个匹配性校验。

            SSLContext sslContext = new SSLContextBuilder()
                    .loadTrustMaterial(null, (TrustStrategy) (chain, authType) -> true)
                    .build();
            HostnameVerifier verifier = (s, sslSession) -> true;
            SSLConnectionSocketFactory factory = new SSLConnectionSocketFactory(sslContext, verifier);
            return HttpClients.custom()
                    .setSSLSocketFactory(factory)
                    .build();
