Examples on how to use the ES CLI to manage scripts - Alibaba Cloud CDN

This topic describes how to use the EdgeScript (ES) CLI to create, save, test, and publish scripts.

Note For more information about how to use the ES CLI, see Use the EdgeScript CLI to configure scripts.

The following examples show how to use the ES CLI to manage scripts:

Save a script as a local file.

For example, use the m3u8.es script to block all M3U8 requests.

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

Publish a script to the staging environment.

$./es.py action=push_test_env domain=<your domain> rule='{"pos":"head","pri":"0","rule_path":"./m3u8.es","enable":"on"}'
