AWS ec2 + uvicorn + fastapi，我得到uvicorn错误 [英] AWS ec2 + uvicorn + fastapi, i get uvicorn error

问题描述

我有一台本地运行的服务器.但是，当我在aws ec2上运行它，并在端口8000上从外部发送请求时，出现此错误.

I have a server running locally. But when I run it on aws ec2, and send a request from outside on port 8000, I get this error.

如果您能告诉我如何在80端口上进行操作，那将是非常不错的.我知道了.

And it would be very nice if you could tell me how to do it on port 80. I am getting .

推荐答案

我得到的是相同的奥秘警告:接收到无效的HTTP请求.错误，并且没有有用的堆栈跟踪.我尝试了所有建议的环境变量调整，但均无效果(请参见 FastAPI问题#680， uvicorn问题#441 ).

I was getting the same arcane WARNING: Invalid HTTP request received. error with an unhelpful stack trace. I tried all of the environment variable tweaks recommended and none worked (see FastAPI issue #680, uvicorn issue #441).

我的问题是，当我调用FastAPI微服务时，当我的微服务不支持HTTPS时，我正在使用 https .我将网址从 https 更改为 http ，它开始按预期运行.

My issue was that when I was calling my FastAPI microservice I was using https when my microservice did not have HTTPS support. I changed the url from https to http and it started working as expected.

请注意，如果您的服务需要HTTPS支持，则可以添加HTTPS支持如Ilgizar Murzakov所建议.

Note that if your service requires HTTPS support you can add HTTPS support as Ilgizar Murzakov suggests.
