php - PHP 放置请求 Philips Hue

Question

我有以下代码来设置飞利浦灯泡的颜色。

<?php

$arrData['hue'] = 46920;
$arrData['sat'] = 254;
$arrData['bri'] = 254;

$data = json_encode($arrData);
echo $data;

$url = "http://MYSITE/api/1234567890/lights/1/state";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PORT, 8078);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");

$response = curl_exec($ch);
echo $response; 

?>

我基本上想向 http://MYSITE:8078/api/USER/lights/1/state 发出 PUT 请求{"hue":46920,"sat":254,"bri":255}，除非它只是超时。这是剪辑 API 调试器的输出

我在做什么不正确？
