Running the HTTP request in an outside tool, rather than my own code, was the key to debugging it. It looks like the problem was caused by an issue in an HTTP helper method on my end. I thought I was setting the HTTP verb to "PATCH" but my helper method was actually overwriting it with "POST", and that was causing the PowerDNS server, naturally, to reject it.
Thanks for your help, Christian. -----Original Message----- From: Christian Hofstaedtler [mailto:[email protected]] Sent: Tuesday, February 03, 2015 3:49 AM To: Jordan Rieger Cc: [email protected] Subject: Re: [Pdns-users] 405 Method Not Allowed error returned from zone update HTTP PATCH method against JSON REST API Hi! > On 03 Feb 2015, at 00:26, Jordan Rieger <jordan at webnames.ca> wrote: > I'm writing code to interface with the HTTP JSON REST API of a PowerDNS 3.4.1 > authoritative server with a MySQL backend.

For what I can see, if you’re able to POST/DELETE zones, PATCH should also work. Can you try the steps with curl outlined in https://doc.powerdns.com/md/httpapi/README/#try-it , as those exactly create a zone and then PATCH it. Based on the instructions from the intro sections, I tried your request with curl, and that does seem to work: curl -X PATCH --data '{"rrsets":[{"name":"example.org","type":"TXT","changetype":"DELETE","records":[],"comments":[]}]}' -H 'X-API-Key: changeme' http://127.0.0.1:8081/servers/localhost/zones/example.org -v < HTTP/1.1 200 OK {"id":"example.org.","url":"/servers/localhost/zones/example.org.","name":"example.org","type":"Zone","kind":"Master","dnssec":false,"soa_edit_api":"","soa_edit":"","masters":[],"serial":2002022401,"notified_serial":0,"last_check":0,"records":[{"name":"bill.example.org","type":"A","ttl":86400,"disabled":false,"content":"192.168.0.3"},{"name":"example.org","type":"MX","ttl":86400,"disabled":false,"content":"10 mail.another.com"},{"name":"example.org","type":"NS","ttl":86400,"disabled":false,"content":"ns1.example.org"},{"name":"example.org","type":"NS","ttl":86400,"disabled":false,"content":"ns2.smokeyjoe.com"},{"name":"example.org","type":"SOA","ttl":86400,"disabled":false,"content":"ns1.example.org. hostmaster.example.org. 2002022401 10800 15 604800 10800"},{"name":"fred.example.org","type":"A","ttl":86400,"disabled":false,"content":"192.168.0.4"},{"name":"ftp.example.org","type":"CNAME","ttl":86400,"disabled":false,"content":"www.example.org"},{"name":"ns1.example.org","type":"A","ttl":86400,"disabled":false,"content":"192.168.0.1"},{"name":"test.example.org","type":"A","ttl":86400,"disabled":false,"content":"1.1.1.1"},{"name":"www.example.org","type":"A","ttl":86400,"disabled":false,"content":"192.168.0.2"}],"comments":[]} Best, -- Christian Hofstaedtler / Deduktiva GmbH (FN 418592 b, HG Wien) www.deduktiva.com / +43 1 353 1707 _______________________________________________ Pdns-users mailing list [email protected] http://mailman.powerdns.com/mailman/listinfo/pdns-users
