codeigniter中的分析api oauth2callback重定向

Question

I have an issue in codeigniter trying to do this example:

Hello Analytics API: PHP quickstart for web applications

Always is redirecting to the auth page

https://accounts.google.com/o/oauth2/auth?response_type=code

I think that the problem is that I can't get the code : $_GET['code']

in the file oauth2callback.php(see the example file in the link)

I tried $_GET['code'] and $this->input->get('code')

and tried in the config 

$config['enable_query_strings']     = TRUE;

and 

$config['enable_query_strings']     = FALSE;

I don't know what else to try.

Thanks

Answer 1

I found the solution :) to get de code must write

$url = parse_url($_SERVER['REQUEST_URI']); parse_str($url['query'], $params);

and $code = $params['code'];

must replace $_GET['code'] with $code or $params['code']

maybe this is useful for someone ^_^
