Implicit assumption of base path

[posener]

I've tried the opencli with a "imposter" mock server that I ran on the same swagger.yaml.

The command to run the mock server, assuming you have a swagger.yaml in CWD:

$ echo '{"plugin":"com.gatehill.imposter.plugin.openapi.OpenApiPluginImpl","specFile":"swagger.yaml"}' > openapi-plugin-petstore-config.json
$ docker run -ti -p 8443:8443 -v $PWD:/opt/imposter/config outofcoffee/imposter-openapi

The mock server serves the swagger.json on http://localhost:8443/_spec/combined.json - under _spec path.
Running open-cli http://localhost:8443/_spec/combined.json -v results in:

Imposter Mock APIs $ pet Create --pet.name=kitty
DEBUG:open-cli:Parsing the input text pet Create --pet.name=kitty
DEBUG:open-cli:Invoke operation <bravado.client.CallableOperation object at 0x7f7e1e977590> with arguments {'pet': {'name': 'kitty'}}
DEBUG:bravado.client:Create({'pet': {'name': 'kitty'}})
DEBUG:urllib3.connectionpool:http://localhost:8443 "POST /_spec/combined.json/api/pets HTTP/1.1" 404 53
ERROR:open-cli:404 Not Found: Response specification matching http status_code 404 not found for operation Operation(Create). Either add a response specification for the status_code or use a `default` response.

The open-cli tries to access the api on path /_spec/combined.json/api/pets instead of /api/pets.

I noticed that imposter modified the swagger: It removed the host and basePath from root of swagger and added it to each path entry.

Might it be the reason?

[sharbov]

The bravado client used by opencli uses the host & basePath to determine the endpoints URLs. If basePath is not specified, it defaults to /.

I've tries reproducing your problem but failed doing so, the said command returned

Imposter Mock APIs $ pet addPet --body.name=test
'photoUrls' is a required property

Failed validating 'required' in schema:
    {'properties': {'category': {'$ref': '#/definitions/Category',
                                 'x-scope': ['http://localhost:8443/_spec/combined.json']},

                               'enum': ['available', 'pending', 'sold'],

                             'xml': {'name': 'tag', 'wrapped': True}}},
     'required': ['name', 'photoUrls'],
     'type': 'object',
     'x-model': 'Pet',
     'xml': {'name': 'Pet'}}

On instance:
    {'name': 'test'}

Which is a valid response.

Can you attach the swagger file you've used.
