使用 Fast API 收到无效的 HTTP 请求

Question

我有一个 React 前端向运行 FastAPI 的 Discord.py 机器人发出请求。在我的测试环境中一切都很好，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()

    event = self._reader(self._receive_buffer)

另外，如果我通过邮递员提出请求，一切都会恢复正常。这是我的主机的问题，还是我缺少的一些 uvicorn 配置的问题？

当微服务不支持HTTPS时更改url为httpshttp
