Failed to create DNSPod record with IPv4.

Error message

Failed to create DNSPod record with IPv4.

What it means

At script/cfst_dnspod.sh:69-74, when get_record_id 'A' returned nothing the script calls create_dns_record, which POSTs to dnsapi.cn/Record.Create (line 34) and extracts .record.id via jq -r '.record.id' (line 36). The failure message at line 73 means that function echoed an empty string: curl produced no response or jq could not run/parse it, so no record id came back. The script never inspects the API status code, and jq -r prints the literal 'null' (non-empty) for a JSON null, so truly empty output usually indicates a curl/jq hard failure rather than a clean API error.

Solutions

Check dependencies: command -v jq curl — install jq if missing
Run the create call by hand and inspect the raw response: curl -s -X POST -d "login_token=$API_TOKEN&format=json&domain=$DOMAIN&sub_domain=$SUB_DOMAIN&record_type=A&record_line=默认&value=1.2.3.4" https://dnsapi.cn/Record.Create
Verify env vars: echo "$API_TOKEN|$DOMAIN|$SUB_DOMAIN" must show 'id,token|your.domain|sub' (API_TOKEN is two parts joined by a comma)
If DNSPod reports the record already exists, pre-create it once in the dashboard so get_record_id finds it and the create path is never taken
Patch create_dns_record to surface errors: check .status.code == '1' and use jq -e -r '.record.id // empty'

Example fix

# script/cfst_dnspod.sh (before)
response=$(curl -s -X POST -d "..." "$dnspod_api_url/Record.Create")
record_id=$(echo "$response" | jq -r '.record.id')
# (after)
response=$(curl -s -X POST -d "..." "$dnspod_api_url/Record.Create")
status=$(echo "$response" | jq -r '.status.code // empty' 2>/dev/null)
[ "$status" = "1" ] || { echo "DNSPod error: $response" >&2; return 1; }
record_id=$(echo "$response" | jq -r '.record.id')

Defensive patterns

Strategy: retry

Validate before calling

command -v jq >/dev/null || { echo 'jq required' >&2; exit 1; }
[ -n "$API_TOKEN" ] && [ -n "$DOMAIN" ] && [ -n "$SUB_DOMAIN" ] || { echo 'API_TOKEN/DOMAIN/SUB_DOMAIN unset' >&2; exit 1; }
curl -sf -o /dev/null https://dnsapi.cn/ || { echo 'dnsapi.cn unreachable' >&2; exit 1; }

Try / catch

resp=$(curl -s -X POST -d "...Record.Create params..." https://dnsapi.cn/Record.Create)
if ! id=$(echo "$resp" | jq -e -r '.record.id // empty' 2>/dev/null) || [ -z "$id" ]; then
  echo "DNSPod create failed: $resp" >&2
fi

Prevention

Install jq and verify with jq --version before relying on the script's parsers
Log and inspect the raw DNSPod response (status.code must be '1') instead of trusting an empty capture
Pre-create the A/AAAA records once in the dashboard so get_record_id finds them and the create path never runs
Keep the API token in 'id,token' form and the shell in a UTF-8 locale so the 默认 record_line survives

When it happens

Trigger: jq not installed (command not found leaves the capture empty); curl failed (no route to dnsapi.cn, TLS error); the response is non-JSON (HTML error page, empty body); API_TOKEN/DOMAIN/SUB_DOMAIN env vars unset so login_token/domain params are empty; the record_line value 默认 mangled by a non-UTF-8 locale; the A record already exists so Record.Create returns an error status without .record.

Common situations: Deploying on a lean router/VPS without jq; forgetting to export API_TOKEN (its format must be 'id,token'); a domain typo so DNSPod returns an error object whose jq path yields null; running with a C locale that corrupts the UTF-8 '默认' record_line value.
