httpclient发送https请求

主要是创建CloseableHttpClient对象时设置一些东西

public static CloseableHttpClient createHttpsClient() throws Exception {
    SSLContext sslContext = new SSLContextBuilder()
            .loadTrustMaterial(null,new TrustStrategy() {
                @Override
                public boolean isTrusted(X509Certificate[] x509Certificates,String s)
                        throws CertificateException {
                    // 直接返回true 不做任何验证
                    return true;
                }
            })
            .build();
    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
    return HttpClients.custom()
            .setSSLSocketFactory(sslsf)
            .build();
}

不知道什么意思，英文的看不懂。。。
的loadTrustMaterial方法还有很多重载，也不太懂
