Php Laravel 5.2社交名媛Facebook API登录重定向错误

我的Facebook登录突然停止使用Laravel 5.2的社交名媛软件包。我已经让它完全发挥功能好几天了，现在它似乎已经停止了。我对拉雷维尔是个新手，所以如果这是件容易的事，请给我一些恩典

我得到这个错误：

“www.facebook.com页面不工作。www.facebook.com重定向您的次数太多了。”

我已经尝试重新启动本地服务器，运行类似于

php-artisan-config:clear

的命令。还尝试使用运行版本为“^2.0”“laravel/socialite”的composer进行安装。我忍不住认为这是Facebook开发者应用程序API配置中的一些东西，但一切看起来都很好

我将提供我的代码，以防任何人有时间来帮助，可以发现任何错误。我用这个链接作为出发的指南

对了，如果有人面临这样的问题，我可以相当肯定你的路由或回调URL有点不正确，无论是在你的

developers.facebook.com

帐户还是你的

.env

文件配置中。在我的

.env

中，我的回调带有附加的

'/'

导致重定向问题的原因：

FACEBOOK\u回调\u URL=http://localhost:8000/auth/facebook/

修复了重定向问题：

FACEBOOK_CALLBACK_URL=http://localhost:8000/auth/facebook

来自Facebook的回调追加了

'/callback？code=xxxxx您的令牌xxxxxx'

因此，对于额外的

“/”

，它似乎混淆了导致重定向循环的回调
