通过CLI工具使用边缘脚本的操作示例_边缘安全加速(ESA)-阿里云帮助中心

本文通过样例为您介绍通过CLI工具使用边缘脚本的操作方法，包括在CLI工具下进行规则的编写、保存、测试和发布的基本操作。

说明 CLI工具的使用方法，请参见通过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"
}

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

测试规则

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