curl请求类实现，具体实现如下：

class HttpRequest{
    private $hostUrl = "http://www.xxx.com";
    private $headers;

    protected function __construct(){
        $this->headers = array('content-type: application/x-www-form-urlencoded;charset=UTF-8;');
    }

    /**
     * 发起http请求
     * @param $postData 请求数据
     * @return mixed
     * @throws HttpException
     * @throws \HttpException
     */
    public function curl($postData){
        $curlPostData = $this->getCurlPostData($postData);

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $this->hostUrl);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $this->headers);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPostData);

        $response = curl_exec($ch);

        /*网络通讯失败*/
        if (curl_errno($ch)) {
            throw new HttpException(false, curl_error($ch));
        } else{
            $httpStatusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

                throw new HttpException($response, $httpStatusCode);
            }
        }

        curl_close($ch);

        return $response;
    }
