req_oauth_bearer_jwt: OAuth with a bearer JWT (JSON web token)

Description

Authenticate using a Bearer JWT (JSON web token) as an authorization grant to get an access token, as defined by Section 2.1 of RFC 7523. It is often used for service accounts, accounts that are used primarily in automated environments.

Learn more about the overall OAuth authentication flow in vignette("oauth").

Usage

req_oauth_bearer_jwt(
  req,
  client,
  claim,
  signature = "jwt_encode_sig",
  signature_params = list(),
  scope = NULL,
  token_params = list()
)
oauth_flow_bearer_jwt(
  client,
  claim,
  signature = "jwt_encode_sig",
  signature_params = list(),
  scope = NULL,
  token_params = list()
)

Value

req_oauth_bearer_jwt() returns a modified HTTP request that will use OAuth; oauth_flow_bearer_jwt() returns an oauth_token.

Arguments

req

A request.

client

An oauth_client().

claim

A list of claims. If all elements of the claim set are static apart from iat, nbf, exp, or jti, provide a list and jwt_claim() will automatically fill in the dynamic components. If other components need to vary, you can instead provide a zero-argument callback function which should call jwt_claim().

signature

Function use to sign claim, e.g. jwt_encode_sig().

signature_params

Additional arguments passed to signature, e.g. size, header.

scope

Scopes to be requested from the resource owner.

token_params

List containing additional parameters passed to the token_url.
