您能否将日期时间格式的逗号或+符号或数据作为codeigniter中URI段的参数传递？ 比如通过ajax调用一个url：controller / function / argument1 / argument2
现在，从前端调用时，此参数1是否包含+，（，），逗号等字符？看起来不是。我尝试通过URI段将地址变量传递给函数，但是地址中出现的+符号，逗号会产生错误。从前端传递的日期格式也是如此。这是限制还是有解决办法？

如果您查看config.php文件夹中的application/config文件，可以找到以下内容：
|--------------------------------------------------------------------------
| Allowed URL Characters
|--------------------------------------------------------------------------
|
| This lets you specify with a regular expression which characters are permitted
| within your URLs. When someone tries to submit a URL with disallowed
| characters they will get a warning message.
|
| As a security measure you are STRONGLY encouraged to restrict URLs to
| as few characters as possible. By default only these are allowed: a-z 0-9~%.:_-
|
| Leave blank to allow all characters -- but only if you are insane.
|
| DO NOT CHANGE THIS UNLESS YOU FULLY UNDERSTAND THE REPERCUSSIONS!!
|
*/
$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';
所以，基本上，你可以改变它以接受你想要的任何符号， 但我真的不知道是什么类型的理由可以让你通过你的uri上面的上述允许符号。
