用PHP编写cUrl的另一种方法

我正试图在hook.io上创建一个服务，以便从另一个API加载令牌。

public function loadToken()
        {
            $computedHash = base64_encode(hash_hmac ( 'md5' , $this->authServiceUrl , $this->password, true ));
            $authorization = 'Authorization: Bearer '.$this->username.':'.$computedHash;
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_POST, true);
            curl_setopt($curl, CURLOPT_POSTFIELDS, '');
            curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization ));
            curl_setopt($curl, CURLOPT_URL, $this->authServiceUrl);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
            $result = curl_exec($curl);
            $obj = json_decode($result);
            $info = curl_getinfo($curl);
            curl_close($curl);
            if($info['http_code'] != '200')
            {
                // print error from the server
                echo($obj);
                return NULL;
            }
            return $obj;
        }

但事实证明hook.io在PHP中不支持cUrl。我知道它可以直接用php完成，但我不知道怎么做。

编辑：我现在使用了fileget_contents，它现在给出了一些其他错误。

$username = '';
$password = '';
$authServiceUrl = '';

$computedHash = base64_encode(hash_hmac ( 'md5' , $authServiceUrl , $password, true ));
$authorization = 'Authorization: Bearer '.$username.':'.$computedHash;
// Create map with request parameters

// Build Http query using params

// Create Http context details
$contextData = array ( 
                'method' => 'POST',
                'header' => "Content-Type: application/json". $authorization ,
                 );
// Create context resource for our request
$context = stream_context_create (array ( 'http' => $contextData ));
// Read page rendered as result of your POST request
$result =  file_get_contents (
                  $authServiceUrl,  // page url
                  false,
                  $context);

我在下方的注释中添加了错误

事实上，据我所知，hook.io支持curl。但是，如果您想尝试其他替代方案，可以使用file_get_contents。它支持自定义上下文和参数。

$opts = [
    'http' => [
            'method' => 'POST',
            'headers' => ['Authorization' => 'Bearer ' . $this->username . ':' . $computedHash]
    ]
];
$context = stream_context_create($opts);
$file = file_get_contents('http://www.hook.io/example/', false, $context);
