OAuth authentication with username and password — req_oauth

This uses oauth_flow_password() to generate an access token, which is then used to authentication the request with req_auth_bearer_token(). The token, not the password is automatically cached (either in memory or on disk); the password is used once to get the token and is then discarded.

Usage

req_oauth_password(
  req,
  client,
  username,
  password = NULL,
  cache_disk = FALSE,
  scope = NULL,
  token_params = list()
)

Arguments

req: A request.
client: An oauth_client().
username: User name.
password: Password. You avoid entering the password directly when calling this function as it will be captured by .Rhistory. Instead, leave it unset and the default behaviour will prompt you for it interactively.
cache_disk: Should the access token be cached on disk? This reduces the number of times that you need to re-authenticate at the cost of storing access credentials on disk. Cached tokens are encrypted and automatically deleted 30 days after creation.
scope: Scopes to be requested from the resource owner.
token_params: List containing additional parameters passed to the token_url.

Value

A modified HTTP request.

Examples

client <- oauth_client("example", "https://example.com/get_token")
req <- request("https://example.com")

if (interactive()) {
  req %>% req_oauth_password(client, "username")
}
