Hello everybody I'm testing rest API, but can't use it, here's what I've been done.
- Installed ez publish on windows, the url of the site was http://localhost/ez.
- Changed my settings to force virtual host and removed the siteaccess if default siteaccess.
- I activated all three extensions and executed the two sql scripts.
- Created a copy of the index_rest.php to the root folder.
- Changed the .htaccess:
Options -Indexes
DirectoryIndex index.php
RewriteEngine On
#Clustered setup switch
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteRule ^/var/([^/]+/)?storage/images(-versioned)?/.* /index_image-common.php [L]
RewriteCond %{HTTP_HOST} ^webdav\..*
RewriteRule ^(.*) webdav.php [L]
RewriteCond %{HTTP_HOST} ^soap\..*
RewriteRule ^(.*) soap.php [L]
RewriteRule ^api index_rest.php [L]
Rewriterule ^/var/static/.* - [L]
RewriteRule ^(.*)favicon\.ico - [L]
RewriteRule ^robots\.txt - [L]
RewriteRule ^sitemap\.xml - [L]
RewriteRule ^var/cache/debug.html.* - [L]
RewriteRule ^var/[^/]+/cache/debug.html.* - [L]
Rewriterule ^var/storage/.* - [L]
Rewriterule ^var/[^/]+/storage/.* - [L]
RewriteRule ^var/cache/texttoimage/.* - [L]
RewriteRule ^var/[^/]+/cache/texttoimage/.* - [L]
RewriteRule ^var/([^/]+/)?cache/public/.* - [L]
Rewriterule ^design/[^/]+/(stylesheets|images|javascript|flash)/.* - [L]
Rewriterule ^share/icons/.* - [L]
Rewriterule ^extension/[^/]+/design/[^/]+/(stylesheets|flash|images|lib|javascripts?)/.* - [L]
Rewriterule ^packages/styles/.+/(stylesheets|images|javascript)/[^/]+/.* - [L]
RewriteRule ^packages/styles/.+/thumbnail/.* - [L]
# Uncomment the following lines when using popup style debug.
# RewriteRule ^var/cache/debug\.html.* - [L]
# RewriteRule ^var/[^/]+/cache/debug\.html.* - [L]
RewriteRule .* index.php [L]
php_value magic_quotes_gpc "Off"
- Registered the oauth application at oauthadmin/list as:
Name: Test
Description: test
Client identifier: 0483e65e220dc2e32bd2cea2b90e068b
Client secret: d475d071de75ebe648e546e46b8e3653
Endpoint URI: http://localhost/rpg/ezpRestDemo.php
- Then I created the file http://localhost/rpg/ezpRestDemo.php:
<?php
/**
* This file is a demonstration of the eZ PUblish REST API developer preview. It handles oAuth2
* authorization, and will return as-is the JSON content returned by the REST interface.
*
* It doesn't cover the whole thing, but almost, and should give you all you need to get started
* with it !
*
* It accepts a few URL parameters that just change which REST resource is used:
* - resource: the REST resource URI that should be queried: content/node/2,
* content/object/1/field/title, etc
* Default: content/node/2
* - output: either json to get raw json, or html to get a preformatted print_r (default)
*
* Setup:
* - place this script in a folder on some web server. The only constraint is that it should be
* able to access your eZ Publish (the one that has REST installed) over HTTP
* - in your eZ Publish backoffice, go to oauthadmin/list. Create a new application. Enter any
* name (it doesn't matter), and enter the URL where you placed this script (the whole thing,
* from http to .php).
* - on the details view for your newly created app (it should be oauthadmin/view/1), you will
* see a "client_id", an md5 sum. Set this value as $appClientId below. It is used to identify
* the application requesting access.
* - set $eZHost below to your eZ Publish host (front or backoffice, doesn't matter)
* - open this script in your browser, WITHOUT parameters, and follow the leader.
* The first time you authenticate, you will be asked if you want to authorize this application.
* Once this is done, you can add parameters, as documented above:
* - output=json will send you direct json. You can find browser plugins in order to view these
* directly.
* - resource must be given the REST resource you want to query. A few you can try until the
* full doc is released:
* - resource=content/node/<id>
* - resource=content/node/<id>/fields
* - resource=content/node/<id>/field/<attribute_identifier>

}
?>The application redirects to the oauth page, I complete the login and I'm redirected back to the page, but I get a 404 error from ez publish. Here's the php 5.3.1 module list: Core, bcmath, calendar, com_dotnet, ctype, date, ereg, filter, ftp, hash, iconv, json, mysqlnd, odbc, openssl, pcre, Reflection, session, SPL, standard, tokenizer, zlib, libxml, dom, bz2, SimpleXML, wddx, xml, xmlreader, xmlwriter, xsl, apache2handler, Phar, curl, mbstring, exif, fileinfo, gd, gettext, imap, mcrypt, mysql, mysqli, PDO, pdo_mysql, PDO_ODBC, pdo_sqlite, soap, sockets, SQLite, sqlite3, xmlrpc, zip, ming, pdf, mhash, xdebug I don't know what I'm doing wrong, could somebody help me?

Changed my demo code and now it works, forget my .htaccess file, just rename default .htaccess_root to .htaccess and change your settings/override/site.ini.append.php [SiteAccessSettings]ForceVirtualHost=true, the steps are the same, you'll just need to change the code I posted to:
