Guzzle returns stream empty body instead of json body
提问by Emeka Mbah
When I use Postman to make an API call I receive a JSON object..which is what I expected.
当我使用 Postman 进行 API 调用时，我收到了一个 JSON 对象……这正是我所期望的。
However When I make same call with Guzzle like so:
但是，当我像这样与 Guzzle 打相同的电话时：
$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
I get dump below from Guzzle
我从 Guzzle 那里得到了转储

getBody()returns a stream. If you want to get all the content at once you can use getContents()method and decode json while at it (if you need to)
getBody()返回一个流。如果您想一次获取所有内容，您可以使用getContents()方法并在其中解码 json（如果需要）
$payload = json_decode($response->getBody()->getContents());

If $response->getBody()->getContents() doesn't work for you, try:
如果 $response->getBody()->getContents() 对您不起作用，请尝试：
$response->getBody()->__toString();
As mentioned here, sometimes getContents's stream pointer is already at the end of stream and then it returns empty response, but __toString resets it by default.
正如这里提到的，有时 getContents 的流指针已经在流的末尾，然后它返回空响应，但 __toString 默认重置它。
