codeigniter、库或助手可以通过 url 访问吗？

在Codeigniter中，有库和助手。我可以访问控制器及其子功能。例如。

login/getid

有没有办法通过 url 访问库或助手？

更新： 我在登录控制器中制作了一个验证码库。我想在许多其他控制器的视图中使用它。在视图文件中，验证码代码应该是这样的，

<img src="/login/get_captcha" />

每次我想使用验证码时，我都必须调用登录控制器。

所以，我认为应该有更好的方法来做到这一点。如果库或助手可以通过 url 访问，我可以将其设置为助手。可以访问另一个控制器的视图，而无需加载登录的控制器。

In Codeigniter, there are library and helper.
I can access controller and its sub function.
for eample.

login/getid

Is there any way to access library or helper through url?

Update :
I made a captcha library in login controller.
I want to use it in many other controller's view.
in view file, the captcha code should be like this,

<img src="/login/get_captcha" />

everytime I want to use captcha, I have to call login controller.

So, I thought that there should be better way to do this.
If library or helper can access through url, I can make this to helper.
can access another controller's view without loading login's controller.

您可以创建一个包装控制器来专门访问这些功能，并使用您的路由来利用所述 URL 的

示例：yoursite.com/helper/geo/citiesNearZip/90210

class helperController extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
        $this->load->helper($this->uri->segment(1)); // geo helper in this example

        if($this->uri->segment(2))
        {
            $helper_method = $this->uri->segment(2);
        }
        else
        {
            show_404();
            return false;
        }

        // check if helper has function named after segment 2, function citiesNearZip($zip) in this example...
        if(function_exists($helper_method)
        {
            // Execute function with provided uri params, xss filter, secure, etc...
            // You would also want to grab all the remaining uri params and pass them as 
            // arguments to your helper function
            $helper_method();
        }
    }
}

You can create a wrapper controller to access those functions exclusively and use your routes to utilize said URL's

Example: yoursite.com/helper/geo/citiesNearZip/90210

class helperController extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
        $this->load->helper($this->uri->segment(1)); // geo helper in this example

        if($this->uri->segment(2))
        {
            $helper_method = $this->uri->segment(2);
        }
        else
        {
            show_404();
            return false;
        }

        // check if helper has function named after segment 2, function citiesNearZip($zip) in this example...
        if(function_exists($helper_method)
        {
            // Execute function with provided uri params, xss filter, secure, etc...
            // You would also want to grab all the remaining uri params and pass them as 
            // arguments to your helper function
            $helper_method();
        }
    }
}
