当我发布params时，Postman无法得到响应，永远加载

Question

这里是我的控制器

  $http = new \GuzzleHttp\Client; $response = $http->post('http://127.0.0.1:8000/oauth/token', [
            'form_params' => [
                'grant_type' => 'password',
                'client_id' => 2,
                'client_secret' => 'vZ2wi8dOIJLueXRzP4Dqvraad0V1GBj3DDy8RaXj,
                'username' => $request->username,
                'password' => $request->password,
            ]
        ]);
  return $response->getBody();

当我发布如下所示的参数时

未得到答复。 请帮助我
