您将Go Web服务与哪个Web服务器一起使用？

If I wanted to create a web service using Go, what web server would I be using?

My web service needs to interact with Mysql, redis and memcached. Are there stable libraries for each?

The net/http package in the standard library is stable and concurrent (goroutine per client).

http.Handle("/foo", fooHandler)

http.HandleFunc("/bar", func(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, %q", html.EscapeString(r.URL.Path))
})

log.Fatal(http.ListenAndServe(":8080", nil))
