为此使用 jq,正如查尔斯·达菲 (Charles Duffy) 的回答所暗示的那样,这是一个非常好的主意.但是,如果您不能或不想安装 jq,那么您可以使用普通 POSIX shell 执行此操作.
Using jq for this, as Charles Duffy's answer suggests, is a very good idea. However, if you can't or do not want to install jq here is what you can do with plain POSIX shell.
#!/bin/sh
set -e
current_ip="$(curl --silent --show-error --fail ipecho.net/plain)"
echo "IP: $current_ip"
# Update A record
curl -X PUT "https://api.cloudflare.com/client/v4/zones/ZONEIDHERE/dns_records/DNSRECORDHERE" \
-H "X-Auth-Email: EMAILHERE" \
-H "X-Auth-Key: AUTHKEYHERE" \
-H "Content-Type: application/json" \
--data @- <<END;
{
"id": "ZONEIDHERE",
"type": "A",
"name": "example.com",
"content": "$current_ip",
"zone_name": "example.com"
}
END
