hutool工具进行https接口调用（忽略ssl认证）

        try {
            SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, getTrustManager(), new SecureRandom());
            return sslContext.getSocketFactory();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
    private static TrustManager[] getTrustManager() {
        TrustManager[] trustAllCerts = new TrustManager[]{
            new X509TrustManager() {
                //检查客户端证书，若不信任该证书抛出异常，咱们自己就是客户端不用检查
                @Override
                public void checkClientTrusted(X509Certificate[] chain, String authType) {
                }
                //检查服务器的证书，若不信任该证书抛出异常，可以不检查默认都信任
                @Override

                }
