gar_api_generator: googleAuthR data fetch function generator

In googleAuthR: Authenticate and Create Google APIs

googleAuthR data fetch function generator

Description

This function generates other functions for use with Google APIs

Usage

gar_api_generator(
  baseURI,
  http_header = c("GET", "POST", "PUT", "DELETE", "PATCH"),
  path_args = NULL,
  pars_args = NULL,
  data_parse_function = NULL,
  customConfig = NULL,
  simplifyVector = getOption("googleAuthR.jsonlite.simplifyVector"),
  checkTrailingSlash = TRUE
)

Arguments

baseURI	The stem of the API call.
http_header	Type of http request.
path_args	A named list with name=folder in request URI, value=the function variable.
pars_args	A named list with name=parameter in request URI, value=the function variable.
data_parse_function	A function that takes a request response, parses it and returns the data you need.
customConfig	list of httr options such as use_proxy or add_headers that will be added to the request.
simplifyVector	Passed to fromJSON for response parsing
checkTrailingSlash	Default TRUE will append a trailing slash to baseURI if missing

Details

path_args and pars_args add default values to the baseURI. NULL entries are removed. Use "" if you want an empty argument.

You don't need to supply access_token for OAuth2 requests in pars_args, this is dealt with in gar_auth()

Add custom configurations to the request in this syntax: customConfig = list(httr::add_headers("From" = "[e-mail]")

Value

A function that can fetch the Google API data you specify

Examples

## Not run: 
library(googleAuthR)
## change the native googleAuthR scopes to the one needed.
options("googleAuthR.scopes.selected" = "email")

get_email <- function(){
   f <- gar_api_generator("https://openidconnect.googleapis.com/v1/userinfo",
                          "POST",
                          data_parse_function = function(x) x$email,
                          checkTrailingSlash = FALSE)
                          
   f()
   }

To use the above functions:
library(googleAuthR)
# go through authentication flow
gar_auth()
s <- get_email()
s

## End(Not run)
