带有gunicorn+uvicorn的openbsd httpd --远程协议错误:非法的请求行

Question

我的web部署设置在openBSD上，由前端的httpd和后端的guicorn + uvicorn引擎组成，通过unix socket连接。

设置是有效的，因为来自httpd的请求是通过unix套接字转发给gunicorn的。但是，gunicorn/uvicorn无法理解传入的http请求。错误堆栈

我不确定非法请求行的潜在原因是什么。

httpd不支持http代理。它支持为静态文件和FastCGI提供服务。和错误消息，指示您的httpd尝试使用FastCGI与gunicorn通信。

因此，如果你坚持使用httpd，那么就找到一种方法来使用FastCGI服务器而不是WSGI (gunicorn)来运行你的应用程序。许多年前，flup是一个流行的选择。

或者，只使用Nginx而不是httpd。
