Symfony 3.3.6 请求参数

Symfony 3.3.6 request parameters

当我 dump($request->request)

时,我可以看到参数被填充
ParameterBag {#69 ▼
  #parameters: array:1 [▼
    "form" => array:8 [▼
      "phone" => "2042333233"
      "price" => "72"
      "region" => "1"
      "accept_terms" => "1"
      "_token" => "XXX"
    ]
  ]
}

但是当我尝试访问参数时:

$request->get('phone')
$request->request->get('phone')

请求是从 POST 填充的 - 因此后者应该可以工作但结果为 NULL???

试试这个:

$request->request->get('form')['phone']
