openbsd-httpd with gunicorn+uvicorn--远程协议错误:请求行非法

Question

我的web部署设置在openBSD上，由前端的httpd和作为后端引擎的guicon+uvicon组成，通过unix套接字连接。

设置是有效的，从这个意义上说，来自httpd的请求通过unix套接字转发到gunicorn。但是，gunicorn/uvicorn无法理解传入的http请求。错误堆栈

我不确定非法请求线路的潜在原因是什么。

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

因此，如果您坚持使用httpd，请找到一种使用FastCGI服务器而不是WSGI(gunicorn(运行应用程序的方法。许多年前，flup是一个流行的选择。

或者，只使用Nginx而不是httpd。
