Guzzlehttp-Guzzle 6에서 응답 본문을 얻는 방법은 무엇입니까?

---

회사에서 개발중인 API 주위에 래퍼를 작성하려고합니다. 편안하고 Postman을 사용하여 http://subdomain.dev.myapi.com/api/v1/auth/POST 데이터로 사용자 이름과 비밀번호 를 사용하여 엔드 포인트에 게시 요청을 보낼 수 있으며 토큰이 다시 제공됩니다. 모든 예상대로 작동합니다. 이제 PHP에서 동일한 작업을 수행하려고하면 GuzzleHttp\Psr7\Response객체를 다시 가져 오지만 Postman 요청으로했던 것처럼 내부에서 토큰을 찾을 수없는 것 같습니다.

관련 코드는 다음과 같습니다.

$client = new Client(['base_uri' => 'http://companysub.dev.myapi.com/']);
$response = $client->post('api/v1/auth/', [
    'form_params' => [
        'username' => $user,
        'password' => $password
    ]
]);

var_dump($response); //or $resonse->getBody(), etc...

위의 코드 출력은 다음과 같습니다 (경고, 들어오는 벽).

object(guzzlehttp\psr7\response)#36 (6) {
  ["reasonphrase":"guzzlehttp\psr7\response":private]=>

    }
  }
  ["protocol":"guzzlehttp\psr7\response":private]=>
  string(3) "1.1"
  ["stream":"guzzlehttp\psr7\response":private]=>
  object(guzzlehttp\psr7\stream)#27 (7) {
    ["stream":"guzzlehttp\psr7\stream":private]=>
    resource(40) of type (stream)
    ["size":"guzzlehttp\psr7\stream":private]=>
    null
    ["seekable":"guzzlehttp\psr7\stream":private]=>
    bool(true)
    ["readable":"guzzlehttp\psr7\stream":private]=>
    bool(true)
    ["writable":"guzzlehttp\psr7\stream":private]=>
    bool(true)
    ["uri":"guzzlehttp\psr7\stream":private]=>
    string(10) "php://temp"
    ["custommetadata":"guzzlehttp\psr7\stream":private]=>
    array(0) {
    }
  }
}

Postman의 결과는 다음과 같습니다.

{
    "data" : {
        "token" "fasdfasf-asfasdfasdf-sfasfasf"
    }
}

Clearly I'm missing something about working with the response objects in Guzzle. The Guzzle response indicates a 200 status code on the request, so I'm not sure exactly what I need to do to retrieve the returned data.

Guzzle implements PSR-7. That means that it will by default store the body of a message in a Stream that uses PHP temp streams. To retrieve all the data, you can use casting operator:

$contents = (string) $response->getBody();

You can also do it with

$contents = $response->getBody()->getContents();

The difference between the two approaches is that getContents returns the remaining contents, so that a second call returns nothing unless you seek the position of the stream with rewind or seek .

$stream = $response->getBody();
$contents = $stream->getContents(); // returns all the contents
$contents = $stream->getContents(); // empty string
$stream->rewind(); // Seek to the beginning
$contents = $stream->getContents(); // returns all the contents

Instead, usings PHP's string casting operations, it will reads all the data from the stream from the beginning until the end is reached.

$contents = (string) $response->getBody(); // returns all the contents
$contents = (string) $response->getBody(); // returns all the contents
