json Encoded URL is not supported in CodeIgniter

[eluser]Joseph1982[/eluser]
Hi,

I have an array and I encoded to create an URL. The array & the URL created is below:

array(10, 12, 13, 45, 1, 2, 5, 78, 111);

http://mysite.com/rest/updatefeeds/[10,12,13,45,1,2,5,78,111]

When I called this URL, I got the following error:

The URI you submitted has disallowed characters


Can someone help me to fix this problem ?

Regards,
Joseph.
