当我尝试启动应用程序时，在heroku中“无法确定Firebase数据库URL”错误是什么意思？

Posted 2023-02-18

我刚刚完成了我的第一个反应应用程序，在这个应用程序中，有一个由Algolia服务生成的搜索栏。因此，我需要创建一个应用程序来记录我的数据库中的每个更改（我使用Firebase）。所以我按照Algolia提出的this tutorial创建了这个应用程序。在本地，当我运行我的应用程序时，一切正常。但是我需要在Heroku上部署这个应用程序，在完成上传到Heroku之后，我使用命令行“heroku open”但是我有一个错误。所以我在我的控制台中启动命令行“heroku logs --tail”，我有以下分析：

似乎这来自我与firebase的连接失败了，虽然我已经在我的.env文件中指定了路径，并且通过指定变量直接在Heroku中指定了路径（有疑问......）

这是我第一次尝试在Heroku上传应用程序。不知道能帮到我吗？

答案

它可以是任何东西，但最有可能的原因如下：

您在本地环境中使用的process.ENV变量在Heroku中不起作用。

在Heroku中，您必须设置所有process.ENV变量，如下所示：

heroku config:set FIREBASE_DATABASE_URL='https://abcd.firebaseio.com'

如果您有更多process.ENV变量，则可以在结尾处设置所有添加空间：

heroku config:set FIREBASE_DATABASE_URL='https://abcd.firebaseio.com'  FIREBASE_API_KEY: '1234'  FIREBASE_AUTH_DOMAIN: 'abc'

或者您可以在Heroku Dashboard中执行此操作：

看看this Heroku web-page两者。
