CDN：樣本：通過CLI工具使用邊緣指令碼

邊緣指令碼的基本操作如下：

• 將編寫的邊緣指令碼規則儲存為本地檔案

  例如：m3u8.es規則攔截所有.m3u8請求

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

• 發布規則至類比環境

  $./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"
  }

• 查看類比環境的規則列表

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

          {
              "Status": "success",    # Status為success時，表示規則已成功設定
              "ConfigId": 17432558,

                  {

                      "ArgValue": "on"
                  }, 
                  {
                      "ArgName": "pri", 
                      "ArgValue": "0"
                  }, 
                  {
                      "ArgName": "pos", 
                      "ArgValue": "head"
                  }, 
                  {

                      "ArgValue": "if eq(substr($uri, -5, -1), '.m3u8') {\n    add_rsp_header('X-DEBUG-DENY-REASON', 'block m3u8')\n    exit(400)\n}\n"
                  }
              ], 
              "FunctionName": "dsl_ex"
          }
      ], 
      "RequestId": "4DDBF3DB-BCAC-4074-AC1E-B6C1F1C6CBFB"
  }

• 測試規則

  $curl -x 類比環境IP:80 -o /dev/null -v 'http://www.archnote.net/test.m3u8'
  < HTTP/1.1 400 Bad Request
  < Server: Tengine
