{“代码”：415，“消息”：“ HTTP 415不支持的媒体类型”} PHP

Question

这是我用于POST CURL PHP的代码，同时尝试调用此代码，这给了我错误，我尝试按照API文档将内容类型为application / json，但实际上还是有人帮助我的相同代码，错误出在哪里或错误

$new_Bot_name = "testname";    
$data = array("body" => $new_Bot_name);
$data_string = json_encode($data);
$curl_hpost = curl_init('https://dashboard.chatfuel.com/api/bots/');
curl_setopt($curl_hpost, CURLOPT_HTTPHEADER,
        array(
            'Authorization: KEY_HERE',
            )
    );

    curl_setopt($curl_hpost, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($curl_hpost, CURLOPT_POSTFIELDS, $data_string);
    curl_setopt($curl_hpost, CURLOPT_RETURNTRANSFER, true);

    //execute post
    $result = curl_exec($curl_hpost);

    //close connection
    curl_close($curl_hpost);

    echo $result;

但是结果如下，有人可以帮助我
