需求
net/http写的http服务,没有任何日志,现在需要添加请求日志,每次http请求时在标准输出打印一行日志
自己实现
package main
import (
"log"
"net/http"
"os"
"time"
)
func RequestLogger(targetMux http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
start := time.Now()
targetMux.ServeHTTP(w, r)
log.Printf(
"%s\t\t%s\t\t%s\t\t%v",
r.Method,
r.RequestURI,
r.RemoteAddr,
time.Since(start),
)
})
}
func SayGoodByeWorld(w http.ResponseWriter, r *http.Request) {
html := "Good Bye World"
w.Write([]byte(html))
}
func SayHelloWorld(w http.ResponseWriter, r *http.Request) {
html := "Hello World"
w.Write([]byte(html))
}
func main() {
log.SetOutput(os.Stdout)
http.HandleFunc("/hi", SayHelloWorld)
http.HandleFunc("/bye", SayGoodByeWorld)
http.ListenAndServe(":8080", RequestLogger(http.DefaultServeMux))
}
输入如下
$ go run main.go
2022/08/01 20:04:19 GET /hi [::1]:52536 8.799µs
2022/08/01 20:04:19 GET /favicon.ico [::1]:52536 28.961µs
2022/08/01 20:04:21 GET /bye?a=b&c=d [::1]:52536 5.467µs
第三方库
https://github.com/gorilla/handlers
http.ListenAndServe(":19888", nil)
改为
import "github.com/gorilla/handlers"
http.ListenAndServe(":19888", handlers.LoggingHandler(os.Stdout, http.DefaultServeMux))
输入如下
10.90.34.133 - - [01/Aug/2022:12:02:11 +0000] "GET /devtestops/devtoapi/workflow/logs?team=framework&flowId=devtestops-ci-devto-server-xmjph HTTP/1.1" 200 1575
