Requests

Classes:

HTTPAdapter(junction_client, **kwargs)	An HTTPAdapter subclass customized to use Junction for endpoint discovery and load-balancing.
Session([default_routes, default_backends, ...])	A drop-in replacement for a requests.Session that uses Junction for discovery and load-balancing.

class junction.requests.HTTPAdapter(junction_client: Junction, **kwargs)

An HTTPAdapter subclass customized to use Junction for endpoint discovery and load-balancing.

You should almost never need to use this class directly, use a Session instead.

Methods:

init_poolmanager(connections, maxsize[, block])	Initializes a urllib3 PoolManager.
send(request[, stream, timeout, verify, ...])	Sends PreparedRequest object.

init_poolmanager(connections, maxsize, block=False, **pool_kwargs)

Initializes a urllib3 PoolManager.

This method should not be called from user code, and is only exposed for use when subclassing the HTTPAdapter.

Parameters:

• connections – The number of urllib3 connection pools to cache.

• maxsize – The maximum number of connections to save in the pool.

• block – Block when no free connections are available.

• pool_kwargs – Extra keyword arguments used to initialize the Pool Manager.

send(

request: PreparedRequest,

stream: bool = False,

timeout: None | float | tuple[float, float] | tuple[float, None] = None,

verify: bool | str = True,

cert: None | bytes | str | tuple[bytes | str, bytes | str] = None,

proxies: Mapping[str, str] | None = None,

) → Response

Sends PreparedRequest object. Returns Response object.

Parameters:

• request – The PreparedRequest being sent.

• stream – (optional) Whether to stream the request content.

• timeout (float or tuple or urllib3 Timeout object) – (optional) How long to wait for the server to send data before giving up.

• verify – (optional) Either a boolean, in which case it controls whether we verify the server’s TLS certificate, or a string, in which case it must be a path to a CA bundle to use

• cert – (optional) Any user-provided SSL certificate to be trusted.

• proxies – (optional) The proxies dictionary to apply to the request.

Return type:

requests.Response

class junction.requests.Session(

default_routes: List[Route] | None = None,

default_backends: List[Backend] | None = None,

junction_client: Junction | None = None,

)

A drop-in replacement for a requests.Session that uses Junction for discovery and load-balancing.
