Node.js 我相信我已经成功地使用heroku CLI进行了构建，但我仍然在URL处遇到应用程序错误

我无法理解为什么我的node/express应用程序不能在Heroku中工作。我相信我已经尝试了文档中的所有建议，而日志似乎对我没有帮助。。。有什么想法吗？我只有邮路。。。没有前端引擎，但邮递员也不工作

赫罗库日志尾

这里的公共git中心：

它是环境变量。。。我明白为什么我要告诉heroku，但我不明白为什么日志中不会出现这样的情况。。。我有大约12个环境变量，所以是的

修复：在应用程序目录/根目录中时

$ heroku config:set JWT_SECRET=[your secret]
$ heroku config:set GOOGLE_CLIENT_ID=[############]
$ heroku config:set FACEBOOK_CLIENT_ID=[########}

再加上十几个。。。在邮递员中工作，预期无法进入/进入浏览器

今天我对heroku和node.js了解了很多

谢谢@JSilv

您有任何环境变量吗？秘密钥匙什么的？确保您现在也为heroku添加了这些内容。在进行heroku配置更改之后，您是否必须添加/commit/push？不管怎么说，只是好奇而已。我知道Heroku可能很敏感，但是一个未定义的env变量会使应用程序崩溃吗？我想那会在某个地方的日志里，对吧？
