CDN：示例：通过CLI工具使用边缘脚本

边缘脚本的基本操作如下：

• 将编写的边缘脚本规则存储为本地文件

  例如：m3u8.es规则拦截所有.m3u8请求

  $cat m3u8.es
  if eq(substr($uri, -5, -1), '.m3u8') {
      add_rsp_header('X-DEBUG-DENY-REASON', 'block m3u8')
      exit(400)
  }

• 发布规则至模拟环境

  $./es.py action=push_test_env domain=<your domain> rule='{"pos":"head","pri":"0","rule_path":"./m3u8.es","enable":"on"}'
  
  Response Code:
  =============
  200 OK
  
  Response Info:
  ==============
  {
      "RequestId": "FB98CC67-8FBA-44CF-A98A-BCE3B19FE510"
  }

• 查看模拟环境的规则列表

  $./es.py action=query_test_env domain=<your domain>
  Response Code:

                  },

                      "ArgName": "pri", 
                      "ArgValue": "0"
                  }, 
                  {

                  }
              ],

          }
      ], 
      "RequestId": "4DDBF3DB-BCAC-4074-AC1E-B6C1F1C6CBFB"
  }

• 测试规则

  $curl -x 模拟环境IP:80 -o /dev/null -v 'http://www.archnote.net/test.m3u8'
