使用 Fast API 接收到的 HTTP 请求无效

Question

我有一个 React 前端向运行 FastAPI 的 Discord.py 机器人发出请求。我的测试环境一切正常，但是当我部署到远程主机时，uvicorn 抱怨

    WARNING:  Invalid HTTP request received.
Traceback (most recent call last):
  File "/home/container/uvicorn/protocols/http/h11_impl.py", line 136, in handle_events
    event = self.conn.next_event()

    exc._reraise_as_remote_protocol_error()

    event = self._reader(self._receive_buffer)

    raise LocalProtocolError("illegal request line")
h11._util.RemoteProtocolError: illegal request line

另外，如果我通过 Postman 提出请求，一切都会再次正常运行。这是我的主机的问题，还是我缺少一些 uvicorn 配置？

当微服务不支持 HTTPS 时，将 url 从 https 更改为 http
