微信开发-生成带参数的二维码及简单使用

// 配置微信

function getWechatAccessToken(){
$appid = appid;
$appsecret = appsecret;
$url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$appid.'&secret='.$appsecret; //获取access_token
$srt = $this->curl('POST',$url);
$strjson=json_decode($srt);
return $token = $strjson->access_token;
}

// 获取access_token
