为什么PHP的cURL在发送https请求的时候可以不用设置CURLOPT_SSL_VERIFYPEER也能请求成功呢？

//下面代码用于更改公众号菜单

public function changeMenu(){

    $wad = new WeixinAdvance();

    $access_token = $wad->access_token;

    $url = 'https://api.weixin.qq.com/cgi-bin/menu/create?access_token='.$access_token;

    $filePath = $_SERVER['DOCUMENT_ROOT']."/../cache2/json/menuconfig.json";

    $json = file_get_contents($filePath); //这是需要传输的json数据哈



    //开始curl请求的各种设置哈

    $curl = curl_init();

    curl_setopt($curl, CURLOPT_URL, $url);

    curl_setopt($curl, CURLOPT_HEADER, 1);

    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);



    curl_setopt($curl, CURLOPT_POST, 1);

    curl_setopt($curl, CURLOPT_POSTFIELDS, $json);



    $output = curl_exec($curl);

    if(curl_errno($curl)){

        echo "存在错误代码：".curl_errno($curl);

    }

    curl_close($curl);

    return $output;

}
