download_xml {xml2}

Download a HTML or XML file

Description

Libcurl implementation of C_download (the "internal" download method) with added support for https, ftps, gzip, etc. Default behavior is identical to download.file(), but request can be fully configured by passing a custom curl::handle().

Usage

download_xml(
  url,
  file = basename(url),
  quiet = TRUE,
  mode = "wb",
  handle = curl::new_handle()
)

download_html(
  url,
  file = basename(url),
  quiet = TRUE,
  mode = "wb",
  handle = curl::new_handle()
)

Arguments

url

A character string naming the URL of a resource to be downloaded.

file

A character string with the name where the downloaded file is saved.

quiet

If TRUE, suppress status messages (if any), and the progress bar.

mode

A character string specifying the mode with which to write the file. Useful values are "w", "wb" (binary), "a" (append) and "ab".

handle

a curl handle object

Details

The main difference between curl_download and curl_fetch_disk is that curl_download checks the http status code before starting the download, and raises an error when status is non-successful. The behavior of curl_fetch_disk on the other hand is to proceed as normal and write the error page to disk in case of a non success response.

For a more advanced download interface which supports concurrent requests and resuming large files, have a look at the multi_download function.

Value

Path of downloaded file (invisibly).
