TNSR API payload requirements

I'm dumb. (don't have it working yet)
Should have paid more attention to the docs.

ok, with better formatted json, I'm now getting a different error.

Failed to find YANG spec of XML node: static with parent: static in namespace: urn:netgate:xml:yang:netgate-nat

the sample code I've put together to do it. I'm getting the feeling it's probably something simple that I'm missing.

payload=dict()
payload['netgate-nat:static']=dict()
payload['netgate-nat:static']['mapping-table']=dict()
payload['netgate-nat:static']['mapping-table']['mapping-entry']=[]

baseport=8732
ipfirst="192.168.49."
externaladdress="myexternalip"
for octet in range(2,3):
    entry=dict()
    entry["local-port"]="3425"
    entry["route-table-name"]="ipv4-VRF:0"
    entry["transport-protocol"]="tcp"
    entry["local-address"]="{}{}".format(ipfirst,octet)
    entry["external-port"]="{}".format(octet+baseport)
    entry["external-address"]=externaladdress
    payload['netgate-nat:static']['mapping-table']['mapping-entry'].append(entry)



import json
import requests

from requests.auth import HTTPBasicAuth
basic = HTTPBasicAuth('username', 'password')

headers = {'Content-type': 'application/yang-data+json'}

url = "http://10.79.79.49/restconf/data/netgate-nat:nat-config/netgate-nat:static"

response = requests.post(url,json=payload,auth=basic,headers=headers)
print(json.dumps(payload))
print(response.text)

payload is

{"netgate-nat:static": {"mapping-table": {"mapping-entry": [{"local-port": "3425", "route-table-name": "ipv4-VRF:0", "transport-protocol": "tcp", "local-address": "192.168.49.2", "external-port": "8734", "external-address": "myexternalip"}]}}}

The trick is making sure the payload and URL agree in that the payload should be contained within the URL's namespace.

This works, for example:

$ curl -k --fail-with-body \
   --cert ~/tnsr/tnsr-myuser.crt \
   --key ~/tnsr/tnsr-myuser.key \
   --cacert ~/tnsr/tnsr-selfca.crt \
   -H "Content-Type: application/yang-data+json" \
   -d '{"netgate-nat:mapping-entry": [{"transport-protocol": "tcp", "local-address": "10.2.0.5", "local-port": "22", "external-address": "203.0.113.2", "external-port": "222", "route-table-name": "ipv4-VRF:0" }]}' \
   -X POST \
   https://198.51.100.2/restconf/data/netgate-nat:nat-config/netgate-nat:static/netgate-nat:mapping-table/

You also have to be careful to scope it correctly. Doing a POST at a higher level than that would create the entire static mapping table (and likewise a PUT would replace it), not individual entries.

You want to be looking at this bit in the docs:

https://docs.netgate.com/tnsr/en/latest/api/netgate-nat.html#tag/nat-config/paths/~1data~1netgate-nat:nat-config~1netgate-nat:static~1netgate-nat:mapping-table/post

Whereas your example was a couple levels too high.

@jimp Thanks!
