langchain.utilities.requests.Requests

class langchain.utilities.requests.Requests(*, headers: Optional[Dict[str, str]] = None, aiosession: Optional[ClientSession] = None, auth: Optional[Any] = None)

Bases: BaseModel

Wrapper around requests to handle auth and async.

The main purpose of this wrapper is to handle authentication (by saving headers) and enable easy async methods on the same base object.

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.
