Online API Doc not working anymore

[humboldtux]

The online API doc is not showing anymore. When i go in "Configuration=>API" and i click on the link "Documentation en ligne de l'API", i get a blank page.

I'm using a simple apache conf on a test server, which was displaying this doc correctly up until recently:

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        ServerName glpi.lan

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

in Administration > config > API, what's the value of the api url in your case.
The link for api inline documentation uses the above parameter.

[humboldtux]

i have the default one: http://glpi.lan:8080/apirest.php/
I also tried to change it to http://glpi.lan:8080/api/, use the provided .htaccess, uncommented, and activate Apache mod rewrite without success.

Hi, if the standard php file does not work, I guess it would not work with a rewrite rule ;)

Most of the times, a blank page executing a PHP script means there is an important issue. You should check your PHP system logs (${APACHE_LOG_DIR}/error.log if you use mod_php) and glpi log files (I guess the issue would be on the system logs).

@trasher you are right, and i didn't think watching the log files, this is what i get that seems relevant when accessing the api doc:

[Mon Sep 19 17:47:06.669771 2016] [:error] [pid 2428] [client 10.0.2.2:34228] PHP Fatal error:  Class 'Michelf\\MarkdownExtra' not found in /var/www/html/glpi.git/inc/api.class.php on line 1767

Looks like your vendor are not up to date :) Try to run a composer install and see if problem still persists.

[humboldtux]

Vendor updated, and doc is back online. Sorry about that.
