   result = api.call('foo', var1=arg1, var2=arg2)
   print result.data

class json_home_client.Client(base_url: str, version: str = None, username: str = None, password: str = None, user_agent: str = None)

The Client constructor takes the base URL for the api, an optional request version identifier, username and password.

Client.base_url: str

The base URL set in the constructor, read-only.

Client.default_version: Optional[str]

The default version information for accept headers.

Client.default_accept: MimeType

The default accept types for API calls.

Client.username: Optional[str]

Username to send in HTTP authentication header.

Client.password: Optional[str]

Password to send in HTTP authentication header.

Client.user_agent: str

The User-Agent string to send in requests.

Client.resource_names: Sequence[str]

A list of available API resource names.

Client.resource(name: str) -> Resource

Get a named Resource.

Client.add_resource(name: str, url: str) -> None

Add a URL resource.

Client.set_version(name: str, version: str = None) -> None

Set the request version identifier for a specific resource. If not set, the default version identifer will be used.

Client.set_accept(name: str, content_type: Union[MimeType, Sequence[MimeType]]) -> None

Set the requested Content-Type(s) for a specific resource. If not set, 'application/json' will be used.

**Client.get(name: str, kwargs) -> Optional[Response]

Perform an HTTP GET on the named resource. Any named arguments supplied may be used in computing the actual URL to call. Returns a Response or None if the resource name is not known.

**Client.post(name: str, payload: bytes, content_type: MimeType = None, kwargs) -> Optional[Response]

Perform an HTTP POST on the named resource. Any named arguments supplied may be used in computing the actual URL to call. Returns a Response or None if the resource name is not known.

**Client.post_form(name: str, payload: Mapping[str, Any] = None, kwargs) -> Optional[Response]

Perform an HTTP POST on the named resource. The payload, if present, will be URL form encoded. Any named arguments supplied may be used in computing the actual URL to call. Returns a Response or None if the resource name is not known.

**Client.post_json(name: str, payload: Any = None, kwargs) -> Optional[Response]

Perform an HTTP POST on the named resource. The payload, if present, will be converted to JSON. Any named arguments supplied may be used in computing the actual URL to call. Returns a Response or None if the resource name is not known.
