Guzzle 返回流空正文而不是 json 正文

当我使用Postman进行API调用时，我会收到一个JSON对象。这是我所期望的。

然而，当我像这样与Guzzle进行相同的通话时：

$client = new \GuzzleHttp\Client(['base_uri' => 'https://api.dev/']);

$response = $client->request('GET', 'search', [
    'verify' => false,
]);

var_dump($response->getBody()); //null

var_dump($response); //returns below

我从Guzzle那里得到了下面的垃圾场
