用户授权出现The key "access_token" could not be empty

[iScript]

我用的环境

PHP 版本：7
overtrue/wechat 版本：3.1

问题及现象

[2016-11-22 00:00:32] local.ERROR: InvalidArgumentException: The key "access_token" could not be empty. in /home/www/wt-game/vendor/overtrue/socialite/src/AccessToken.php:33

平常测试基本没出现，都能正常运行。但每天看laravel的错误日志都有几千条这样的错误日志。
都是同一个方法里的， 以下是详细错误日志：

我也遇到了这个情况，我用的中间件，应该是用户在授权失败页面刷新导致的。

[overtrue]

那是错误的使用啊，授权失败就不应该刷新啊，那我也解决不了啊

[iScript]

应该不是重复刷新导致的。
我在oauth页面Session::put('fo', '1');
在callback页面 判断了，重复刷新会自动跳转到oauth页面。
function callback(){
if(!Session::get('fo')){
return redirect("/wechat/oauth");
}
Session::forget("fo");
}

可还是会出现这错误

[xiaohuilam]

我也出现，并非授权失败。

环境：SwooleFramework，PHP 7.09
经过测试，没有调用到overtrue/wechat/src/Core/AccessToken
网络出流量抓包，给微信的请求的access_token没有带

此为bug~

[overtrue]

@iScript @Sunappnio @xiaohuilam 请更新版本：

$ composer update overtrue/socialite -vvv

[iScript]

我看了下请求微信的日志，code倒是每次都有带的， 不知道是不是微信有时会2次redirect回来的原因。有什么好的解决办法。。
