如何将gorilla mux与http.TimeoutHandler一起使用 [英] How to use gorilla mux with http.TimeoutHandler

问题描述

在go中写入的HTTP服务器中，我使用大猩猩/多路复用器进行路由， >
我想使用 http.TimeoutHandler （和/或其他中间件），但我无法理解我可以在哪里适合它们。

In an HTTP server written in go, I use gorilla/mux for routing,
I want to use http.TimeoutHandler (and/or other "middleware") but I can't understand where I can fit them.

为了说清楚：

To make it clear:

1. 我通过创建一个新的路由器， gorillaMux：= mux.NewRouter（）


2. 通过像> gorillaMux.HandleFunc（/，rootHandler） code>


3. 我通过 server：=& http.Server {Addr：：1234}创建服务器和 server.ListenAndServe（）

1. I create a new Router by gorillaMux := mux.NewRouter()
2. add my routes by calls like gorillaMux.HandleFunc("/", rootHandler)
3. I create the server by server := &http.Server{Addr:":1234"} and server.ListenAndServe()

在哪里可以插入 http.TimeoutHandler 或任何其他中间件？

Where can I insert the http.TimeoutHandler or any other middleware for that matter?

推荐答案

可以这样做：

Here is how you can do this:

package main

import (
    "fmt"
    "github.com/gorilla/mux"
    "net/http"
    "time"
)

func rootHandler(w http.ResponseWriter, r *http.Request) {
    time.Sleep(5 * time.Second)
    fmt.Fprintf(w, "Hello!")
}

func main() {
    mux := mux.NewRouter()
    mux.HandleFunc("/", rootHandler)

    muxWithMiddlewares := http.TimeoutHandler(mux, time.Second*3, "Timeout!")

    http.ListenAndServe(":8080", muxWithMiddlewares)
}

如果您有多个HTTP处理程序，您可以将它们堆叠在一起：

If you have more than one HTTP handler, you can stack them up:

// this is quite synthetic and ugly example, but it illustrates how Handlers works
muxWithMiddlewares := http.StripPrefix("/api", http.TimeoutHandler(mux, time.Second*3, "Timeout!"))
