创建工具类，在创建连接对象前调用该方法

import javax.net.ssl.*;
import java.security.SecureRandom;

public class HttpsUtil {

                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }

        }

}

 发送https请求跳过授信

public static CloseableHttpClient createSSLClientDefault() {
        try {

                    return true;
                }
            }).build();
            //NoopHostnameVerifier类:  作为主机名验证工具，实质上关闭了主机名验证，它接受任何
            //有效的SSL会话并匹配到目标主机。
            HostnameVerifier hostnameVerifier = NoopHostnameVerifier.INSTANCE;
            SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext, hostnameVerifier);
            return HttpClients.custom().setSSLSocketFactory(sslsf).build();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyStoreException e) {
            e.printStackTrace();
