Enable Query Strings in Code Igniter

I am trying to implement Twitter's OAuth into my Code Igniter web application at which the callback URL is /auth/ so once you have 开发者_JAVA技巧authenticated with Twitter you are taken to /auth/?oauth_token=SOME-TOKEN.

I want to keep the nice clean URL's the framework provides using the /controller/method/ style of URL but I want to enable query strings as well, there will only ever be one name of the data oauth_token so it's ok if it has to be hard coded.

Any ideas? I have tried tons of the things people are saying to do, but none work :( PS: I'm using the .htaccess method of URL rewriting.

There are several ways to handle this.

Most People, and Elliot Haughin's Twitter Lib, extend the CI_Input library with a MY_Input library that sets allow_query_strings to true

You will also need to add ? to the allowed characters in config/config.php and set $config['url_protocal'] to PATH_INFO

see here: Enable GET in CodeIgniter

Codeigniter Reactor lets you access $_GET directly or via $this->input->get(). You don't need to use MY_Input or even change your config.php. This method leaves the query string in the URL, however.

I used a hacked index.php to recognise users coming back from Twitter, check for valid and safe values, then re-direct it to to a CodeIgniter friendly URL.

It may not be to everyones taste but I preferred it over allowing query strings throughout the entire application instead of just one particular circumstance.
