        }        
        $data1 = \[

        $result = self::https\_request($url,$data1);        
        echo 'success';
    }

   //上传素材到微信
    public static function uploadImg($img,$access\_token)

        $url = 'https://api.weixin.qq.com/cgi-bin/media/upload?access\_token='.$access\_token.'&type=image';

下面的都是通用代码

    //获取access\_token
    public static function getAccessToken()
    {
        $appid = Yii::$app->params\['miniAppid'\];        
        $appsecret = Yii::$app->params\['miniSecret'\];        
        $url = 'https://api.weixin.qq.com/cgi-bin/token?grant\_type=client\_credential&appid='.$appid.'&secret='.$appsecret;        
        $result = self::httpGet($url);        
        $access\_token = json\_decode($result,true)\['access\_token'\];        
        return $access\_token;
    }

    //get方法获取内容
    private static function httpGet($url)
    {
        $curl = curl\_init();
        curl\_setopt($curl, CURLOPT\_RETURNTRANSFER, true);
        curl\_setopt($curl, CURLOPT\_TIMEOUT, 500);
        curl\_setopt($curl, CURLOPT\_SSL\_VERIFYPEER, 2);
        curl\_setopt($curl, CURLOPT\_SSL\_VERIFYHOST, 2);
        curl\_setopt($curl, CURLOPT\_URL, $url);        
        $res = curl\_exec($curl);
        curl\_close($curl);        
        return $res;
    }

    //http请求
    public static 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;
    }
