Re: [VuFind-Tech] Voyager Hold/Recall Functionality

[Greg P. <Gre...@us...>]

Obviously we aren't running voyager, but might it be a solution to basically fake vufind as a proxy server on the users' behalf?

eg. When you send the request use:
$_SERVER['REMOTE_ADDR'] = your server IP
$_SERVER['HTTP_X_FORWARDED_FOR'] = client's IP

So you look like a nicely behaving (and transparent) proxy server.

Then when the user connects it _might_ work. This is just a stab in the dark though.




For Virtua we ended up faking the login on the users' behalf inside the OPAC and avoided the issue altogether:

public function renewItems($patron, $item_list) {
  // Stuff

  // Fake a login to get an authenticated session
  $session_id = $this->fakeLogin($patron);

  $virtua_url = "http://$web_server/cgi-bin/chameleon";
  $client = new HTTP_Request();
  $client->setMethod(HTTP_REQUEST_METHOD_POST);
  // More stuff

  $result = $client->sendRequest();
}
After we stop hearing people say "I loved the old catalogue, why did you change." We'll firewall off the system altogether.

Subject: [VuFind-Tech] Voyager Hold/Recall Functionality

Just discovered that the hold/recall links in our VuFind installation are not working -- they go to a Voyager login page, but the page is malformed (the drop-down to the left of the barcode entry box is empty but should show a sample barcode number), and filling in the form just leads to a dead-end error screen.

The current VuFind Voyager driver works by screen-scraping links from the web catalog.  The problem seems to be that the links are system-specific.  A link served to the VuFind server works if it's accessed from the server, but if it's passed along to a VuFind client, it no longer functions.  It's nothing to do with cookies or sessions, since I can access a working URL in multiple web browsers, and as long as I stay on the same computer, it continues to work...  but if I try to access it from a different box, it won't work.  Maybe IP address is being hashed into one of the parameters or something like that.  Since Voyager is essentially a black box, this is a hard one to understand or work around.

I notice some discussion about broken Voyager hold functionality back in March or April, but I see no clear resolution.  Did this ever work right?  Is it working now for any of the other Voyager libraries?

thanks,
Demian
