How to return pure json

Hello,

I want to respond with json without spaces or line breaks.
This is because the size of the large json grows unnecessarily.

PHP Code:

  public function testapi()
  {
    $data = ['test1' => 1, 'test2'=> 2];
    return $this->response->setJSON($data);
  } 


response

Code:

{
    "test1": 1,
    "test2": 2
}

Is there a good way?

Have you tried with your environment set to production? It looks like it will not "pretty print" json in production. I don’t know if there’s a way to change this.

When I put it in production mode, the problem was solved.
Thank you!
