langchain.utilities.requests.Requests

class langchain.utilities.requests.Requests[source]

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.

param aiosession: Optional[aiohttp.client.ClientSession] = None
param auth: Optional[Any] = None
param headers: Optional[Dict[str, str]] = None
adelete(url: str, **kwargs: Any) AsyncGenerator[ClientResponse, None][source]

DELETE the URL and return the text asynchronously.

aget(url: str, **kwargs: Any) AsyncGenerator[ClientResponse, None][source]

GET the URL and return the text asynchronously.

apatch(url: str, data: Dict[str, Any], **kwargs: Any) AsyncGenerator[ClientResponse, None][source]

PATCH the URL and return the text asynchronously.

apost(url: str, data: Dict[str, Any], **kwargs: Any) AsyncGenerator[ClientResponse, None][source]

POST to the URL and return the text asynchronously.

aput(url: str, data: Dict[str, Any], **kwargs: Any) AsyncGenerator[ClientResponse, None][source]

PUT the URL and return the text asynchronously.

classmethod construct(_fields_set: Optional[SetStr] = None, **values: Any) Model

Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed. Behaves as if Config.extra = ‘allow’ was set since it adds all passed values

copy(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, update: Optional[DictStrAny] = None, deep: bool = False) Model

Duplicate a model, optionally choose which fields to include, exclude and change.

Parameters
  • include – fields to include in new model

  • exclude – fields to exclude from new model, as with values this takes precedence over include

  • update – values to change/add in the new model. Note: the data is not validated before creating the new model: you should trust this data

  • deep – set to True to make a deep copy of the model

Returns

new model instance

delete(url: str, **kwargs: Any) Response[source]

DELETE the URL and return the text.

dict(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, by_alias: bool = False, skip_defaults: Optional[bool] = None, exclude_unset: bool = False, exclude_defaults: bool = False, exclude_none: bool = False) DictStrAny

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

classmethod from_orm(obj: Any) Model
get(url: str, **kwargs: Any) Response[source]

GET the URL and return the text.

json(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, by_alias: bool = False, skip_defaults: Optional[bool] = None, exclude_unset: bool = False, exclude_defaults: bool = False, exclude_none: bool = False, encoder: Optional[Callable[[Any], Any]] = None, models_as_dict: bool = True, **dumps_kwargs: Any) unicode

Generate a JSON representation of the model, include and exclude arguments as per dict().

encoder is an optional function to supply as default to json.dumps(), other arguments as per json.dumps().

classmethod parse_file(path: Union[str, Path], *, content_type: unicode = None, encoding: unicode = 'utf8', proto: Protocol = None, allow_pickle: bool = False) Model
classmethod parse_obj(obj: Any) Model
classmethod parse_raw(b: Union[str, bytes], *, content_type: unicode = None, encoding: unicode = 'utf8', proto: Protocol = None, allow_pickle: bool = False) Model
patch(url: str, data: Dict[str, Any], **kwargs: Any) Response[source]

PATCH the URL and return the text.

post(url: str, data: Dict[str, Any], **kwargs: Any) Response[source]

POST to the URL and return the text.

put(url: str, data: Dict[str, Any], **kwargs: Any) Response[source]

PUT the URL and return the text.

classmethod schema(by_alias: bool = True, ref_template: unicode = '#/definitions/{model}') DictStrAny
classmethod schema_json(*, by_alias: bool = True, ref_template: unicode = '#/definitions/{model}', **dumps_kwargs: Any) unicode
classmethod update_forward_refs(**localns: Any) None

Try to update ForwardRefs on fields based on this Model, globalns and localns.

classmethod validate(value: Any) Model
