Pass GET param which is another URL with PHP - Codeigniter 3, Apache

Question

I want to pass URL in GET param like this :

SITE URL/b16ee4f31e17df0d3af5?url=https%3A%2F%2Fwww.facebook.com%2F

I am using urlencode to escape characters, but I see 403 Error for this URL, because of some of the characters in the URL GET parameter in this case the dot character.

If I use CI3 function url_title , it will escape dot characters, but I need them because I need valid url in GET parameter.

How can I pass URL get parameter with in some cases with characters like . & ? \\ . & ? \\ . & ? \\ and other characters which can be found in the standart URL ?

Answer 1

You can change $config['permitted_uri_chars'] in your config file

Leave blank to allow all characters -- but only if you are insane.

Also you can do this:

Step 1: $newurl = urlencode(base64_encode('http://google.com'));

Then you will have a string, pass that string as GET parameter and parse it back using:

$realUrl = base64_decode(urldecode($param1));

Where $param1 means the first param of your controller.

Step 2: add = to your $config['permitted_uri_chars'] in your config file

Answer 2

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';

add the character what you trying to pass on GET Url. This configure is store on config.php of config folder.

该网址已被编码（也就是说，您只是从地址栏中复制并粘贴了该网址），因此可以将其用于进一步的编码
