创建转发策略

功能介绍

创建转发策略。监听器和转发策略共同决定了流量如何转发到后端云服务器上。

• 通过匹配action为REDIRECT_TO_POOL的转发策略下的转发规则的url和域名，可以将匹配的流量转发到指定的后端云服务器组上，再将流量分发到在这个后端云服务器组关联的后端云服务器上。
• 可以通过创建action为REDIRECT_TO_LISTENER的转发策略，将HTTP监听器的流量都重定向到TERMINATED_HTTPS监听器上，实现请求协议的重定向。

接口约束

当前只支持HTTP协议跳转到HTTPS协议。即当转发策略的action为REDIRECT_TO_LISTENER时，转发策略的listener_id指定的监听器只支持HTTP类型的监听器，redirect_listener_id指定的监听器只支持TERMINATED_HTTPS类型的监听器。

转发策略的redirect_listener只能指定为转发策略所在负载均衡器下的监听器。

调试

您可以在API Explorer中直接运行调试该接口。
