request_generate function

Build a request for the Google Drive API

Build a request, using knowledge of the Drive v3 API from its Discovery Document (https://www.googleapis.com/discovery/v1/apis/drive/v3/rest). Most users should, instead, use higher-level wrappers that facilitate common tasks, such as uploading or downloading Drive files. The functions here are intended for internal use and for programming around the Drive API.

request_generate() lets you provide the bare minimum of input. It takes a nickname for an endpoint and:

• Uses the API spec to look up the path, method, and base URL.
• Checks params for validity and completeness with respect to the endpoint. Separates parameters into those destined for the body, the query, and URL endpoint substitution (which is also enacted).
• Adds an API key to the query if and only if token = NULL.
• Adds supportsAllDrives = TRUE to the query if the endpoint requires.

request_generate(
  endpoint = character(),
  params = list(),
  key = NULL,
  token = drive_token()
)

Arguments

• endpoint: Character. Nickname for one of the selected Drive v3 API endpoints built into googledrive. Learn more in drive_endpoints().

• params: Named list. Parameters destined for endpoint URL substitution, the query, or the body.

• key: API key. Needed for requests that don't contain a token. The need for an API key in the absence of a token is explained in Google's document "Credentials, access, security, and identity" (https://support.google.com/googleapi/answer/6158857?hl=en&ref_topic=7013279). In order of precedence, these sources are consulted: the formal key

  argument, a key parameter in params, a user-configured API key fetched via drive_api_key(), a built-in key shipped with googledrive. See drive_auth_configure() for details on a user-configured key.

• token: Drive token. Set to NULL to suppress the inclusion of a token. Note that, if auth has been de-activated via drive_deauth(), drive_token() will actually return NULL.

Returns

list()

Components are method, path, query, body, token, and url, suitable as input for request_make().

Examples

req <- request_generate(
  "drive.files.get",
  list(fileId = "abc"),
  token = drive_token()
)
req
