我将PHP请求库用于http请求：
$url = Qrcode_url;
$data = array(
'amount'=> 12,
'currency'=>'USD',
'reference'=>'123456765432',
'ipn_url'=>'http://website.com/ipn'
);
// $token
$headers = array("Authorization" => "Bearer 123456", 'Content-Type' => 'application/json');
$options = $data;
$request = Requests::post($url, $headers, array());
echo '<pre>';
print_r($request);
这是我屏幕上的输出：
Requests_Response Object

上面是错误，您看到我在请求中将Content-Type标头更改为application/json，但是为什么会出现上面的错误？
令牌正确，请注意，错误打印中的请求标头仍为text/html。我该如何解决我的问题？
