Ddns scripts have the same url path problem

[hexoxssaa]

Hey, guys! I have writed two custom scripts (refer to: https://github.com/openwrt/packages/blob/openwrt-22.03/net/ddns-scripts/samples/update_sample.sh), one for ipv4, another for ipv6.
they look like this:

local __URL="https://dnsapi.cn/Record.Ddns"
# ipv4
local __POSTDATA="login_token=1234567890&sub_domain=ipv4"
# ipv6
local __POSTDATA="login_token=1234567890&sub_domain=ipv6"


/usr/libexec/wget-ssl -nv -t 1 -O $DATFILE -o $ERRFILE -U "IPUpdater/1.0.1 (122232139@qq.com)" --no-check-certificate --post-data="$__POSTDATA" "$__URL" || return 1

write_log 7 "DDNS Provider answered:\n$(cat $DATFILE)"

grep -i -E '\\u64cd\\u4f5c\\u5df2\\u7ecf\\u6210\\u529f\\u5b8c\\u6210' $DATFILE >/dev/null 2>&1
return $?	# "0" if "good" or "nochg" found

And in the ddns luci page, I have configed two services:

Here comes the problem: the services run Simultaneously, and they generate the same $DATFILE, "Record.Ddns" in the same path "/usr/lib/ddns/".
It means one service may read a wrong output file which is from an other service!

Please tell me how to fix it, thanks!

Topic closed!
At last I found out the "Record.Ddns" file is an temporary test file I created months ago!
Sorry, my fault!

@hexoxssaa

they generate the same $DATFILE

$DATFILE is defined here in the following way: DATFILE="$ddns_rundir/$SECTION_ID.dat"

Make sure you have unique section id's by running uci show ddns
Do not name your sections like "aaa.bbb" (Record.Ddns or alike), e.g. make it simpler like dnspod4, dnspod6.
