POST JSON vs. urlencoded

Until now I had tested POST to the REST API only with content-type
application/x-www-form-urlencoded -- this works fine. Now I've started
testing with application/json and I'm getting a traceback where a
type-check on the id for a link fails in the rdbms backend with the
message "link value must be String".
Now it turns out, the check there compares the value it gets to type('')
but gets a unicode id from the REST API. The RDBMS backend (at least in
Python2) should get UTF-8 encoded strings, not unicode. So my guess is
that somewhere in the guts of the REST API there is a decode() step
missing.

Example working POST (urlencoded) (deleted some headers):

POST /job-log/rest/data/issue HTTP/1.1
User-Agent: python-requests/2.12.4
Content-Length: 179
Content-Type: application/x-www-form-urlencoded

status=waiting-for-confirmation&customer=1505609&demo_rq_id=4711081542421&title=Noch+ein+test&messages=228&priority=normal&salesperson=22&org_link=1&crm_requester=22&opportunity=1

Exampe not-working POST (json) (deleted some headers):
POST /job-log/rest/data/issue HTTP/1.1
User-Agent: python-requests/2.12.4
Content-Length: 233
Content-Type: application/json

{"status": "waiting-for-confirmation", "customer": "3", "demo_rq_id": "471108154242", "title": "Noch ein test", "messages": "228", "priority": "normal", "salesperson": "22", "org_link": "1", "crm_requester": "22", "opportunity": "1"}


When using the python request library, reproducing this is simple:
I prepare the value dictionary and the I either use

session = requests.session()
session.auth = (username, password)

d = dict (...)

# for the urlencoded payload:
r = session.post (url + 'issue', data = d)
#for the JSON payload:
r = session.post (url + 'issue', json = d)


Did anyone already test modifying methods (POST, PUT, PATCH) with a json
payload?

John, how did you test so far?
