Codeigniter - URI不允许的字符


I have seen several other questions similar to this but I can't find a solution to my specific problem.

I am getting error The URI you submitted has disallowed characters. When I send the following request:


Now I have identified that the % in my username is what is triggering the error but I have that allowed in my config file.

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

I though this should allow % to be allowed in the url. If I set config as

$config['permitted_uri_chars'] = '';

Works fine. Is the config string not correct? Or is there another variation of the string I should be using?

  • doushan7997 doushan7997 4年前 is actually, but urlencoded.

    So, the disallowed character you are sending is @, not %.

    If you add "@" to your permitted_uri_chars you should be alright.

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