微信公众号开发最近和前端配合出现的问题

前面我在微信测试号后台设置的auth认证的域名是后台的,自己去获取code,自己授权都是没问题的,忘了前端请求如果使用重定向到前端就是不行,关键点来了:

首先应该是前端自己去请求微信获取到code,auth域名认证配置前端的域名,前端截取到code后,授权已经结束了,把code传到后台,让后台去后去数据就可以了,后台将用户数据获取到写入数据库,直接return给前端就好了,php代码只要一个接口就好了

报token跨域在harder头添加

header("Access-Control-Allow-Headers:token,DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type, Accept-Language, Origin, Accept-Encoding");

 public function getuseropenid()
    {
        //回调地址会传回一个code，则我们根据code去获取openid和授权获取到的用户信息
        $code = $_GET['code'];
        error_log("\n******" . date("Y-m-d H:i:s") . "********\n" . print_r($code, 1) . "\n*************\n", 3, 'messag_event.log');

        $appid = Config::get('weixin.appid');
        $secret = Config::get('weixin.appsecret');

        $url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=" . $appid . "&secret=" . $secret . "&code=" . $code . "&grant_type=authorization_code";
