附录：

第一个函数：weixin_upload

public function weixin_upload($type = 'image',$filepath = './')

	$access_token = $this->get_token();
	$filedata = array('media' => "@".$filepath);

	$url = "http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token=$access_token&type=$type";
	$res = https_request($url,$filedata);
	return json_decode($res);
}

 public function https_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, 1);
      $output = curl_exec($curl);
      curl_close($curl);
      return $output;
  }

第三个函数：get_token;

public function get_token(){
	 $this->_appid = '你的appid';
	 $this->_sercet = '你的appsercet';
	 $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->_appid&secret=$this->_sercet";
	 //当然 这里 最好做个缓存 
	 $res = file_get_contents($url);
	 $res = json_decode($res);

	 return $res->access_token;
 }

public function weixin_download($media_id='',$type='jpg'){
     
	 $token = $this->get_token();
	 $url = "http://file.api.weixin.qq.com/cgi-bin/media/get?access_token=$token&media_id=$media_id";
	 $filedata= file_get_contents($url);
	 $newpath = 你的文件存放路径."文件名.".$type;
 	 file_put_contents($newpath,$filedata);
 }
