Python AWS ec2&x2B；乌维康+；fastapi，我得到uvicorn错误

我有一台本地运行的服务器。但当我在AWSEC2上运行它，并在端口8000上从外部发送请求时，我得到了这个错误

我也遇到了同样的问题，并通过添加HTTPS支持解决了这个问题。我使用LetsEncrypt证书配置了NGINX。请确保您使用的端口在您的安全组设置中处于打开状态。
我收到了相同的神秘警告：接收到无效的HTTP请求。

错误，堆栈跟踪无效。我尝试了所有envi建议对环境变量进行调整，但没有任何调整有效（请参见）

我的问题是，当我调用FastAPI微服务时，我使用的是

https

，而我的微服务没有https支持。我将url从

https

更改为

http

，它开始按预期工作

请注意，如果您的服务需要HTTPS支持，您可以按照Ilgizar Murzakov的建议进行操作。
