分组HttpsPolicy的设置
用户可以再分组上调整API分组所支持的HTTPS安全策略，HTTPS安全策略仅对绑定了域名及证书的分组有效，目前API网关支持HTTPS1_1_TLS1_0,HTTPS2_TLS1_0,HTTPS2_TLS1_2安全策略，但不同Region支持的安全策略列表不同，在控制台->分组详情页可选择本Region支持的HTTPS安全策略
HTTPS安全策略列表
HTTPS1_1_TLS1_0
- HTTP1.1协议
- 支持TLS v1.0 , TLS v1.1 , TLS v1.2
- 支持加密算法套件：ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA:AES128-GCM-SHA256:AES128-SHA256:AES128-SHA:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:AES256-GCM-SHA384:AES256-SHA256:AES256-SHA:ECDHE-RSA-AES128-SHA256:!aNULL:!eNULL:!RC4:!EXPORT:!DES:!3DES:!MD5:!DSS:!PKS;
HTTPS2_TLS1_0
- HTTP2协议, 注意: http2协议会将所有的header转为小写
- 支持TLS v1.0 , TLS v1.1 , TLS v1.2
- 支持加密算法套件：ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA:AES128-GCM-SHA256:AES128-SHA256:AES128-SHA:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:AES256-GCM-SHA384:AES256-SHA256:AES256-SHA:ECDHE-RSA-AES128-SHA256:!aNULL:!eNULL:!RC4:!EXPORT:!DES:!3DES:!MD5:!DSS:!PKS;
HTTPS2_TLS1_2
- HTTP2协议, 注意: http2协议会将所有的header转为小写
- 支持TLS v1.2, 注意: 所有不支持TLS v1.2客户端将无法建立连接
- 支持加密算法套件：ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-RSA-AES256-SHA:!NULL:!aNULL:!MD5:!ADH:!RC4:!DH:!DHE:!3DES;
