PHP通用CURL类，可POST/GET/文件传输

function do_curl($url, $params = array(), $upload = false, $type = 'POST')
{
    $method = strtoupper($type);
    if ($method == 'GET') {
        $url = "{$url}?" . http_build_query($params);
    }

    // //定义请求类型
    //       curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    // curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
    // 是否检测服务器的证书是否由正规浏览器认证过的授权CA颁发的
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    // 是否检测服务器的域名与证书上的是否一致
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    // var_dump($params);die;
    if ($method == 'POST') {
        if ($upload) {        //设置上传文件
            $file = new CURLFile($upload['tmp_name'], $upload['type'], $upload['name']);
            $params[$upload['get_name']] = $file;
        }
        @curl_setopt($ch, CURLOPT_POST, 1);
        @curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
    }
    $result = curl_exec($ch);
    curl_close($ch);
    if ($result === null || $result === false) {
        $this->error('操作出错！');
    } else {
