我在Magento2订单API连接上遇到错误

Question

可捕获的致命错误：无法在此行上将stdClass类的对象转换为字符串

  

curl_setopt（$ ch，CURLOPT_HTTPHEADER，array（“ Content-Type：   application / json“，”授权：承载“。json_decode（$ token）））;

$userData = array("username" => "xxxx", "password" => "xxxxxx");
    $ch = curl_init("http://magento2.local.com/index.php/rest/V1/integration/admin/token");
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($userData));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Content-Lenght: " . strlen(json_encode($userData))));

    $token = curl_exec($ch);

    $ch = curl_init("http://magento2.local.com/index.php/rest/V1/orders/1");
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Authorization: Bearer " . json_decode($token)));

    $result = curl_exec($ch);

    $result = json_decode($result, 1);
    echo '<pre>';print_r($result);
