list_entities error

[dherykw]

Hello @chicco785

I am giving a try to this tool :-)

I have tried to list some entities but orion is complain about some headers. This is the code that I tried:

api_client = ApiClient(host='http://192.168.1.122:1026')
api_client.set_default_header('fiware-service', 'parking')
api_client.set_default_header('fiware-servicepath', '/parking')
api_instance = swagger_client.EntitiesApi(api_client)

 r = api_instance.list_entities()

print(r)

Orion returns the following response:

HTTP response headers: HTTPHeaderDict({'Connection': 'Keep-Alive', 'Content-Length': '163', 'Content-Type': 'application/json', 'Fiware-Correlator': 'c6e49922-dec4-11e9-bbd2-02420a000b0d', 'Date': 'Tue, 24 Sep 2019 12:13:54 GMT'})
HTTP response body: {"orionError":{"code":"400","reasonPhrase":"Bad Request","details":"Orion accepts no payload for GET/DELETE requests. HTTP header Content-Type is thus forbidden"}}

Orion does not allow the Content-Type It could just ignore the content if it would be present but... :S

It seems that it can be fixed just redefining the swagger but I can't find it.

Best

Sure! As soon as I have the swagger file or know how to generate it with the client, I can give it a try

@dherykw have a look at this repo: https://github.com/orchestracities/sdk
i realised this one is not maintained recently.
you can find swagger under specs (also for quantumleap).

look at this comment:
https://github.com/orchestracities/sdk/blob/master/python/ngsi_v2/.openapi-generator-ignore#L11

i think the issue is not swagger related, but you can check (in case of js it's the code generator to be wrong). for python i believe we didn't much tests (we so far mostly use js)

Hello @chicco785
I was also struck in this problem where I tried to run the APIEntryPointApi and other GET requests but the Orion Context Broker would return the same response that @dherykw mentioned
swagger_client.rest.ApiException: (400) Reason: Bad Request HTTP response headers: HTTPHeaderDict({'Date': 'Thu, 25 Jun 2020 18:10:30 GMT', 'Fiware-Correlator': '27bd734a-b70f-11ea-940c-0242ac130003', 'Connection': 'Keep-Alive', 'Content-Type': 'application/json', 'Content-Length': '131'}) HTTP response body: {"error":"BadRequest","description":"Orion accepts no payload for GET/DELETE requests. HTTP header Content-Type is thus forbidden"}

The problem here is that the Orion Context Broker does not accepts HTTP header Content-Type. But the GET request prepared in the rest.py file contains Header value. I just removed that to solve the issue.

# ForGET, HEADelse: print('This is for GET', headers) r = self.pool_manager.request(method, url, fields=query_params, preload_content=_preload_content, timeout=timeout, headers=headers)
The last line is where the problem lies. Just change it to headers=None.

Could you explain ho to set headers=None ? I'm strugling with the same issue, thanks!
