php5.6+上传公众号素材，由于php版本不同，导致curl也得有变化

php5.5上下的php版本的CURL有差异

php5.5版本(包含)以下:

public function upload_temporary_material($type, $file)
    {
        if (PHP_OS == "Linux"){        //Linux
            $data = array("media"  => "@".dirname(__FILE__).'/'.$file);
        }else{                        //WINNT
            $data = array("media"  => "@".dirname(__FILE__).'\'.$file);
        }
        $url = "https://api.weixin.qq.com/cgi-bin/media/upload?access_token=".$this->access_token."&type=".$type;
        $res = $this->http_request($url, $data);
        return json_decode($res, true);
    }
protected function http_request($url, $data = null)
    {
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
        if (!empty($data)){
            curl_setopt($curl, CURLOPT_POST, 1);
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
        }
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
        $output = curl_exec($curl);
        curl_close($curl);
        return $output;
    }

5.5的会报一个让你用CURLFile()来代替，但是不影响使用

php5.5版本以上:

    public function upload_temporary_m($type, $file)
    {
        $url = "https://api.weixin.qq.com/cgi-bin/media/upload?access_token=".$this->access_token."&type=".$type;
        $res = $this->http_request1($url, $file);
        return json_decode($res, true);
    }
    
    protected function http_request1($url,$path){
        $curl = curl_init();
 
        curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true);
        $data = array('file' => new CURLFile(realpath($path)));//
        curl_setopt($curl, CURLOPT_URL, $url); 
        curl_setopt($curl, CURLOPT_POST, 1 ); 
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data); 
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt($curl, CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']); 
        $result = curl_exec($curl);
        return $result;
    }
