Send nested array via Laravel Http Client

Question

I want to send request to an API website containing nested params via Laravel Http Client (Laravel 7.x)

$params = [
   'type' => 'books',
   'variables' => [
      'color' => 'red',
      'size' => 'large'
   ]
]

I want my url to like this:

http://example.com/?type=books&variables={"color":"red","size":"large"}

encoded above url:

http://example.com/?type=books&variables=%7B%22color%22%3A%22red%22%2C%22size%22%3A%22large%22%7D

But when I use:

Http::get('http://example.com', $params);

The API server returns error.

But when I use:

Http::get('http://example.com/?type=books&variables={"color":"red","size":"large"}');

It works well.

So how can I convert my params array into url ?

(I don't have access to API server)

Answer 1

try json_encode()

 $params = [
            'type' => 'books',
            'variables' => json_encode([
               'color' => 'red',
               'size' => 'large'
            ])
         ]

$url = "http://example.com?".http_build_query($params);

Http::get($url);
