    private function curlPost($url, $post_vars = '', $referer = null)
    {

        $this->lastURL = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
        $this->lastStatus = curl_getinfo($ch, CURLINFO_HTTP_CODE);

        return $html;
    }
}

并通过以下方式调用：

<?php
$new = $_GET['t'];
include_once('nest.php');
$nest = new Nest('usr', 'pwd');
$nest->temperature_set($new);
?>

如果我用一个数字替换$ new然后调用它可以工作的函数但不是当前形式。我已经尝试使用该类来调用外部变量，试图只是调用但不能解释它在哪里以及为什么它不起作用。

我怀疑它无法正常工作，因为您的设备已配置为使用Celsius。

PHP是一种动态类型语言，JavaScript也是如此，但有时人们会忘记两者都会根据上下文更改类型（有时类型转换会产生意外结果）。

所有$ _REQUEST变量都是字符串。尝试更改：

$target_temp_celsius = $temp;

要

$target_temp_celsius = $temp + 0;

（JSON是强类型的）

引用实例中的变量
