Go Web App：如何从Golang将PHP脚本路由到PHP-FPM

Question

I have one main web site and numerous small web sites. I'm currently using Nginx & PHP for all of this. My plan is to do away with both and build a single web app in Go that will serve everything, which will hopefully reduce load and memory (especially since some of the pages are very computationally heavy.)

My issue is that it would be a serious waste of time for me to try to port things like rarely used PHPBB forums to Go. So I'd like to have the main web site all served from the Go web app, but some of the other sites can remain as PHP.

My question is: can I use the Go web app to route requests for PHP scripts to PHP-FPM?

I would like it so that I can do away with Nginx, the web app will handle all of the incoming traffic and serve the main site directly from its own code, but for less important sites that are still in PHP these can be served by the Go app routing these requests to PHP-FPM (along with all the full request info including cookies, POST vars, etc.)

Any ideas?

To redirect to another url you can use httputil.HostReverseProxy

    origin := "http://php.website.com"
    originUrl, err := url.Parse(origin)
    if err != nil {
        log.Fatal(err)
    }

    proxy := httputil.NewSingleHostReverseProxy(originUrl)
    prev := proxy.Director

    proxy.Director = func(req *http.Request) {
        prev(req)
        req.Host = originUrl.Host
    }

    http.HandleFunc("/php", proxy.ServeHTTP)
