在路由中使用可选参数

Question

I want to use same route in 2 scenarios,

1. use route without passing parameter
2. use route with parameter

So, is it possible & how to do it?

Answer 1

You can optional parameters like this

Route::get('my-method/{param?}', function ($param= null) {
// your code here
});

Answer 2

In Web Php

Route::get('find-services/{service_name?}', 'commonController@find_services')->name('find-services');

and handle the parameters in commonController.php

public function find_services($service_name = null) {// Do something here}

Or Simple use the get method and check parameter in Controller

public function find_services() {
    $input = Request::all();
    if (isset($input['service_name']) AND ! empty($_GET['service_name'])) {
        // Code
    }
}
