copied!<p>I got the impression that <code>url.el</code> was designed mostly for interactive operations, i.e. you do a call without authorisation, the server responds with a 403 "authorization needed" (correct code?) status and <code>url.el</code> will query the user for user name and password.</p> <p>You can have a look at my code on <a href="http://github.com/hdurer/fluiddb.el/" rel="noreferrer">http://github.com/hdurer/fluiddb.el</a> where I try to do things programmatically.</p> <p>Basically, I create the HTTP authorzation header myself (base64 encoding the correctly formatted string and adding the correct header to <code>url-request-extra-headers</code>). Then in a second step I need to add advice to <code>url-http-handle-authentication</code> so that it won't ask the user should the passed credentials not be acceptable.</p> <p>This feels a lot like raping <code>url.el</code> but it works for me and is the only way I could make it work.</p> <hr> <p>Your code would thus look something like this:</p> <pre><code> (defvar xyz-user-name "admin") (defvar xyz-password "admin") (defvar xyz-block-authorisation nil "Flag whether to block url.el's usual interactive authorisation procedure") (defadvice url-http-handle-authentication (around xyz-fix) (unless xyz-block-authorisation ad-do-it)) (ad-activate 'url-http-handle-authentication) (defun login-show-posts () (interactive) (let ((xyz-block-authorisation t) (url-request-method "GET") (url-request-extra-headers `(("Content-Type" . "application/xml") ("Authorization" . ,(concat "Basic " (base64-encode-string (concat xyz-user-name ":" xyz-password))))))) (url-retrieve "http://localhost:3000/essay/1.xml" (lambda (status) (switch-to-buffer (current-buffer)) )))) </code></pre>
