Bulk DNS resolution always returns an error Malformed JSON in request body

This is the address I requested.
curl -X POST -H “X-Auth-Key:**********” -H "X-Auth-Email:[email protected]" -H “Content-Type: application/json” “https://api.cloudflare.com/client/v4/zones/39fae479863f92b180635c3ea285b9fd/dns_records” --data ‘{“type”:“A”,“name”:“11549.com”,“content”:“127.0.0.1”,“ttl”:{1},“priority”:10,“proxied”:false}’

ttl should be an integer. You specified an object without valid content.

Thank you, my problem has been solved.
