laravel - 从 http 请求中获取参数

Question

I want to pass in multiple parameters from my Angular app to my Laravel API, namely the id and choices array supplied by user.

Angular:

http request:

verifyAnswer: function(params) {
    return $http({
        method: 'GET',
        url: 'http://localhost:8888/api/questions/check',
        cache: true,
        params: {
            id: params.question_id,
            choices: params.answer_choices
        }
    });

Laravel 5:

routes.php:

$router->get('/api/questions/check/(:any)', 'ApiController@getAnswer');

ApiController.php:

public function getAnswer(Request $request) {
    die(print_r($request));
}

I thought I should use :any within my URI to indicate I'll be passing in an arbitrary amount of parameters of various data structure (id is a number, choices is an array of choices).

How can I make this request?

Update for Laravel 8:

Sometimes you may want to pass in parameters without using query strings.

EX

Route::get('/accounts/{accountId}', [AccountsController::class, 'showById'])

In your controllers method, you can use a Request instance and access the parameters like so using the route method:

public function showById (Request $request)
{
  $account_id = $request->route('accountId')
  
  //more logic here
}

But if you still wanted to use some query params then you can use that same Request instance and just use the query method

Endpoint: https://yoururl.com/foo?accountId=4490

 public function showById (Request $request)
{
  $account_id = $request->query('accountId');
  
  //more logic here
}

Change this:

$router->get('/api/questions/check/(:any)', 'ApiController@getAnswer');

to

$router->get('/api/questions/check', 'ApiController@getAnswer');

And fetch the values with

echo $request->id;
echo $request->choices;

in your controller. There is no need to specify that you will receive parameters, they will all be in $request when you inject Request to your method.
