Details

webmockr package required for mocking behavior

Examples

## Not run:

if (interactive()) {
  library(webmockr)
  library(crul)

  URL <- "https://hb.opencpu.org"

  # turn on mocking
  crul::mock()

  # stub a request
  stub_request("get", file.path(URL, "get"))

  # create an HTTP client
  (x <- HttpClient$new(url = URL))

  # make a request - matches stub - no real request made
  x$get('get')

  # allow net connect
  webmockr::webmockr_allow_net_connect()
  x$get('get', query = list(foo = "bar"))
  webmockr::webmockr_disable_net_connect()
  x$get('get', query = list(foo = "bar"))

  # With Async
  urls <- c(
   file.path(URL, "get"),
   file.path(URL, "anything"),
   file.path(URL, "encoding/utf8")
  )
  
  for (u in urls) {
    webmockr::stub_request("get", u) %>% 
      webmockr::to_return(body = list(mocked = TRUE))
  }

  async_con <- Async$new(urls = urls)
  async_resp <- async_con$get()
  lapply(async_resp, \(x) x$parse("UTF-8"))
}
