Crawlable AJAX with _escaped_fragment_ in htaccess

Question

Hello to all the developers!

We are almost done developing the first phase of our ajax web application. In our application, we use hash fragments, such as:

http://ourdomain.com/#!list=last_ads&order=date 

I understand that Google will select this URL and make a request to the server in this form:

 http://ourdomain.com/?_escaped_fragment_=list=last_ads?order=date&direction=desc 

everything is perfect except ...

I would like to redirect this request to another script

So:

 RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$ RewriteRule ^$ /webroot/crawler.php$1 [L] 

The problem is that when I try print_r ($ _ REQUEST) in crawler.php I get only:

 Array ( [_escaped_fragment_] => list=last_ads?order=date [direction] => desc ) 

I would like to receive

 Array ( [list] => last_ads [order] => date [directions] => des ) 

I know that I can use php to further break the first argument, but I don't want to;)

please inform

Answer 1

Your forgotten QSA directive (everyone missed the dot = D)

 RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$ RewriteRule ^$ /webroot/crawler.php%1 [QSA,L] 

By the way, your $1 well mistaken ... useless because it means nothing. So this should be:

 RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$ RewriteRule ^$ /webroot/crawler.php [QSA,L] 

Tell me if this works.

Answer 2

If I'm not mistaken.

 RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$ RewriteRule ^$ /webroot/crawler.php?%1 [L] 

Answer 3

This may be obvious to you, but the documentation talks about escaped characters: Configure the server to process requests for URLs containing

The crawler avoids certain characters in the fragment during conversion. To get the original fragment, be sure to cancel all% XX characters in the fragment. More specifically,% 26 should become &,% 20 should become space,% 23 should be #, and% 25 should be%, etc.

Answer 4

Here is a solution that allows you to properly configure the URL and request parameters for processing on the server side script.

Example: If you want http://yoursite.com/#!/product/20 become http://yoursite.com/crawler/product/20

First in .htaccess

 RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$ RewriteRule ^$ /crawler/index.php?_frag=%1 [L] 

We need to get rid of _escaped_fragment_ in the URL and replace it with something else, for example: _frag so that the web server (Apache) does not get into circular rewrites.

Second in crawler/index.php

 <?php if(array_key_exists('_frag', $_REQUEST)) { $_SERVER['REQUEST_URI']=$_REQUEST['_frag']; unset($_REQUEST['_frag']); parse_str($_SERVER['QUERY_STRING'], $frag); parse_str(preg_replace('/^.*\?/', '', $frag['_frag']), $_REQUEST); $_SERVER['QUERY_STRING'] = http_build_query($_REQUEST); } // Continue with your usual script of routing // $_REQUEST now contains the original query parameters

In htacess, working in a virtual host does not work, so I add to the "directory"

 <Directory "X:/DIR"> RewriteEngine On RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$ RewriteRule ^$ /crawler/index.php?_frag=%1 [L] </Directory>
