Subject: Function to download a URL and return it as a string
Date: Sat, 08 Dec 2012 21:17:38 -0800 [thread overview]
Message-ID: <m2k3srerd9.fsf@gmail.com> (raw)
I recently wanted to be able to download a document from a URL and
return it as a string. I couldn't find a function that did that
precisely, but I was able to construct my own:
(defun download (url)
(with-current-buffer (url-retrieve-synchronously url)
(prog2
(when (not (search-forward-regexp "^$" nil t))
(error "Unable to locate downloaded data"))
(buffer-substring (1+ (point)) (point-max))
(kill-buffer))))
This seems rather busy for such a basic-seeming operation--in
particular, having to take care to delete the buffer created by
url-retrieve-synchronously. Is there a better way to do it?
(On the other hand, this way I get to use prog2, which I almost never
do.)
