來自外部API和Symfony 3項目的Guzzle HTTP GET的意外$響應

Question

我使用Guzzle在我的Symfony 3項目中執行來自外部API的HTTP GET請求。這裏是我的控制器代碼：

<?php 

namespace AppBundle\Controller; 

use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; 
use Symfony\Component\HttpFoundation\Response; 
use Symfony\Component\HttpFoundation\Request; 
use Psr\Http\Message\ResponseInterface; 
use GuzzleHttp\Client; 

class ScheduleController extends Controller { 

/** 
* @Route("/schedule") 
*/ 

public function getJobs() { 
    // Create a client with a base URI 
    $client = new \GuzzleHttp\Client(['base_uri' => 'http://my.external.api/']); 
    // Send a request to http://my.external.api/site/67/module/1449/item 
    $response = $client->request('GET', 'site/67/module/1449/item', ['auth' => ['****', '****']]); 
    var_dump($response); 
    exit; 
    return $this->json(array($response)); 
} 
} 

我正在以下從我的代碼var_dump($response)：

object(GuzzleHttp\Psr7\Response)#397 (6) { ["reasonPhrase":"GuzzleHttp\Psr7\Response":private]=> string(2) "OK" ["statusCode":"GuzzleHttp\Psr7\Response":private]=> int(200) ["headers":"GuzzleHttp\Psr7\Response":private]=> array(11) { ["Date"]=> array(1) { [0]=> string(29) "Tue, 24 Jan 2017 19:39:17 GMT" } ["Server"]=> array(1) { [0]=> string(6) "Apache" } ["Cache-Control"]=> array(2) { [0]=> string(35) "no-cache, no-store, must-revalidate" [1]=> string(46) "no-cache, no-store, max-age=0, must-revalidate" } ["Pragma"]=> array(2) { [0]=> string(8) "no-cache" [1]=> string(8) "no-cache" } ["Expires"]=> array(2) { [0]=> string(1) "0" [1]=> string(1) "0" } ["X-Content-Type-Options"]=> array(1) { [0]=> string(7) "nosniff" } ["X-XSS-Protection"]=> array(1) { [0]=> string(13) "1; mode=block" } ["X-Frame-Options"]=> array(1) { [0]=> string(4) "DENY" } ["Set-Cookie"]=> array(1) { [0]=> string(64) "SiteIdentifier=67; Expires=Wed, 25-Jan-2017 19:39:17 GMT; Path=/" } ["Transfer-Encoding"]=> array(1) { [0]=> string(7) "chunked" } ["Content-Type"]=> array(1) { [0]=> string(30) "application/json;charset=UTF-8" } } ["headerNames":"GuzzleHttp\Psr7\Response":private]=> array(11) { ["date"]=> string(4) "Date" ["server"]=> string(6) "Server" ["cache-control"]=> string(13) "Cache-Control" ["pragma"]=> string(6) "Pragma" ["expires"]=> string(7) "Expires" ["x-content-type-options"]=> string(22) "X-Content-Type-Options" ["x-xss-protection"]=> string(16) "X-XSS-Protection" ["x-frame-options"]=> string(15) "X-Frame-Options" ["set-cookie"]=> string(10) "Set-Cookie" ["transfer-encoding"]=> string(17) "Transfer-Encoding" ["content-type"]=> string(12) "Content-Type" } ["protocol":"GuzzleHttp\Psr7\Response":private]=> string(3) "1.1" ["stream":"GuzzleHttp\Psr7\Response":private]=> object(GuzzleHttp\Psr7\Stream)#395 (7) { ["stream":"GuzzleHttp\Psr7\Stream":private]=> resource(328) 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) { } } }

當我通過Postman運行HTTP GET，我得到的結果，如：

"fields":[{"options":[{"id":23034,"value":"Ready for scheduling"}],"fieldDefinitionId":16444,"name":"Job Status"}

什麼是$response我目前Ly gets，以及如何從我的外部API獲取我正在尋找的內容的JSON數組響應？

Answer 1

您必須返回一個Symfony的迴應，Symfony的3.1，你可以用the json controller helper：

return $this->json(json_decode($response->getBody())); 

Answer 2

由於他們homepage顯示，獲得響應body：

// 'application/json; charset=utf8' 
echo $response->getBody(); 
// {"type":"User"...' 

// to return from controller 
return json_decode($response->getBody());
