在python中，requests.get(url,verify=False)  设置一下就ok。

# 参考文章：轻松把玩HttpClient之配置ssl，采用绕过证书验证实现https #

httpclient不能直接访问https的资源，这次就来模拟一下环境，然后配置https测试一下。在前面的文章中，分享了一篇自己生成并在tomcat中配置ssl的文章《Tomcat配置SSL》，大家可以据此来在本地配置https。我已经配置好了，效果是这样滴：

可以看到已经信任该证书（显示浅绿色小锁），浏览器可以正常访问。现在我们用代码测试一下：

public static void main(String[] args) throws ParseException, IOException, KeyManagementException, NoSuchAlgorithmException, HttpProcessException {
            String url = "https://sso.tgb.com:8443/cas/login";
            String body = send(url, null, "utf-8");
            System.out.println("交易响应结果：");
            System.out.println(body);
            System.out.println("-----------------------------------");
        }

发现抛出了异常，我知道的有两种方案（也许还有我不知道的方案），这里介绍第一种方案，也是用的比较多的方案——绕过证书验证。直接看代码吧：

/**
         * 绕过验证
         *     
         * @return
         * @throws NoSuchAlgorithmException 
         * @throws KeyManagementException 
         */
        public static SSLContext createIgnoreVerifySSL() throws NoSuchAlgorithmException, KeyManagementException {
            SSLContext sc = SSLContext.getInstance("SSLv3");
     
            // 实现一个X509TrustManager接口，用于绕过验证，不用修改里面的方法
            X509TrustManager trustManager = new X509TrustManager() {
                @Override
                public void checkClientTrusted(
                        java.security.cert.X509Certificate[] paramArrayOfX509Certificate,
                        String paramString) throws CertificateException {
                }
     
                @Override
                public void checkServerTrusted(
                        java.security.cert.X509Certificate[] paramArrayOfX509Certificate,
                        String paramString) throws CertificateException {
                }
     
                @Override
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return null;
                }
            };
     
            sc.init(null, new TrustManager[] { trustManager }, null);
            return sc;
        }
    然后修改原来的send方法：
        /**
         * 模拟请求
         * 
         * @param url        资源地址
         * @param map    参数列表

         * @throws ClientProtocolException

        public static String send(String url, Map<String,String> map,String encoding) throws KeyManagementException, NoSuchAlgorithmException, ClientProtocolException, IOException {

            EntityUtils.consume(entity);
            //释放链接
            response.close();
            return body;
        }

现在再进行测试，发现果然通了。
