Guzzle - 400 Bad Request` response：{“error”：“invalid_client”} - 制作令牌请求时

Question

我试图使用guzzle做出令牌请求并收到错误“400 Bad Request”响应：{“error “：” invalid_client “}”。我可以用cURL和HTTP_Request2进行同样的请求，没有任何问题。

<?php 
    require 'vendor/autoload.php'; 
    use GuzzleHttp\Client; 
    use GuzzleHttp\Exception\RequestException; 
    use GuzzleHttp\Psr7\Request; 

    session_start(); 
    if(isset($_GET['code'])){ 
     $code = $_GET['code']; 
     $encodeB64 = base64_encode('{clientID}:{clientSecret}'); 
     $client = new GuzzleHttp\Client(); 
     $response = $client->request('POST', 'https://identity.reckon.com/connect/token',[ 
     ['headers' => ['Content-Type' => 'application/x-www-form-urlencoded'],['Authorization' => 'Basic '.$encodeB64]], 
     ['body' => ['grant_type' => 'authorization_code'],['code' => $code],['redirect_uri' => '{redirectURI}']] 
     ]); 
     $body = $response->getBody(); 
     echo $body; 
    } 

这些是如何使这个API令牌请求的细节：

网址：https://identity.reckon.com/connect/token

类型：POST

身体：grant_type = authorization_code &码= {代码} & redirect_uri = {redirect url}

插头：

• 的Content-Type =应用程序/ x-WWW窗体-urlencoded

• 授权：基本{客户ID：在base64编码的客户端机密}

不知道在哪里，我出错了。

我已经完成了。答案是如下：

<?php 
    require 'C:/Users/Shane/vendor/autoload.php'; 
    use GuzzleHttp\Client; 
    use GuzzleHttp\Exception\RequestException; 
    use GuzzleHttp\Psr7\Request; 

    session_start(); 
    if(isset($_GET['code'])){ 
     $code = $_GET['code']; 
     $encodeB64 = base64_encode('{client id}:{client secret}'); 
     $authbody = 'grant_type=authorization_code&code='.$code.'&redirect_uri={redirect url}'; 
     $client = new GuzzleHttp\Client(); 
     $response = $client->request('POST', 'https://identity.reckon.com/connect/token',['headers' => 
      ['Content-Type' => 'application/x-www-form-urlencoded','Authorization' => 'Basic '.$encodeB64], 
      'body' => $authbody]); 
     $body = $response->getBody(); 
     echo $body;
