How to multiplex requests for different domains to different servers using Go?
问题
我想在同一台机器上托管多个域名，使用不同端口运行多个服务器。我正在尝试编写一个多路复用器，它将把对域名"A"的请求重定向到本地运行在"portA"上的服务器，将对域名"B"的请求重定向到运行在"portB"上的服务器。如何在保持对用户和搜索引擎机器人透明的同时路由这些请求？
目前，我使用类似以下的代码：
package main
import (
"net/http"
"log"
)
func main() {
mux := http.NewServeMux()
mux.Handle("mydomainA.com", http.RedirectHandler("http://localhost:1234", 302))
mux.Handle("mydomainB.com", http.RedirectHandler("http://localhost:4567", 302))
log.Fatal(http.ListenAndServe(":8080", mux))
}
英文:
I want to host multiple domains on the same machine, with multiple servers running on the same machine and different ports. I am trying to write a multiplexer which will redirect requests for domain "A" to the server running locally on "portA", and requests for domain "B" to the server running on "portB". How can I route those requests, while making this redirect transparent to the user and search-engine bots?
Currently, I use something like this:
package main
import (
"net/http"
"log"
)
func main() {
mux := http.NewServeMux()
mux.Handle("mydomainA.com", http.RedirectHandler("http://localhost:1234", 302))
mux.Handle("mydomainB.com", http.RedirectHandler("http://localhost:4567", 302))
log.Fatal(http.ListenAndServe(":8080", mux))
}

你想要使用 httputil.ReverseProxy 类型，它来自于 net/http/httputil 包。

(just posting @james-odoherty's comment as an answer since he hasn't)
You want to use the httputil.ReverseProxy type from the net/http/httputil package.
