Heroku python flask应用程序无法运行，但在本地主机上运行良好？

python sqlite flask heroku

Heroku python flask应用程序无法运行，但在本地主机上运行良好？,python,sqlite,flask,heroku,Python,Sqlite,Flask,Heroku,基本上我的网站上有些人的标题是这样的：当我尝试登录时，什么也没有发生，我填写了Recpatca输入正确的详细信息，但页面只是刷新，什么也不做，但是当我在本地主机上进行时，它工作正常，我可以登录并正常完成所有事情。 我也尝试过删除recaptcha的内容，在本地主机上运行良好，但在heroku上仍然存在相同的问题。希望有更多知识的人能帮忙。如果需要，我可以链接我的github repo。最初我遇到一个错误，python告诉我安装python dotenv，所以我安装了它并将其添加到requirem

我还在heroku命令行上设置了env变量，我看到了您的存储库，您正在使用site.db means sqlite。问题是。您应该使用heroku中的插件来存储数据

转到概述选项卡>单击配置加载项>搜索heroku postgres>选择加载项类型（免费或付费）>如果要查看
数据库URL
>用此替换
SQLALCHEMY\u数据库URI
，请转到设置中的配置变量

SQLALCHEMY_DATABASE_URI = os.environ.get('SQLALCHEMY_DATABASE_URL')
安装
psycopg2
并添加到requirements.txt。

当代码运行时，您应该在文件中写入或记录一些信息，以查看执行的代码部分以及变量中包含的内容。也许这样你会发现问题的根源。也许问题不在于ReCaptcha，而在于数据库或邮件。你没有显示
视图
，因此我们不知道你在对表单中的数据做什么。如果你看一下，我可以向你显示我的视图。我的网站昨天写得很好。我已将登录视图添加到question@furas这是完整的代码我追踪到了网站上的所有其他工作，但是在heroku上，登录和注册没有任何作用，就像它只是刷新和保持不变一样，也没有flash消息，但是在我的本地主机上，一切都很好，我该怎么做呢，idk为什么现在不使用数据库它在herokuyep上工作吗？我昨天部署的它似乎工作得很好，现在我测试它，只是不做任何事情。你可以访问我的网站并尝试我的github还有链接。该网站的代码是flask应用程序，我想问题出在第42行users/routes.py上。代码似乎从未执行过，它执行第53行第42行下面的代码，并打印一条语句来验证它。
