Golang创建简单的http/https服务

HTTP服务

package main

import (
    "net/http"
    "fmt"
    "log"
)

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request){
        fmt.Fprint(w, "Hello world")
    })
    log.Fatal(http.ListenAndServe(":5001", nil))
}

HTTPS服务

package main

import (
    "log"
    "net/http"
)

func handler(w http.ResponseWriter, req *http.Request) {
    w.Header().Set("Content-Type", "text/plain")
    w.Write([]byte("This is an example server.\n"))
}

func main() {
    http.HandleFunc("/", handler)
    log.Printf("About to listen on 10443. Go to https://127.0.0.1:10443/")
    // One can use generate_cert.go in crypto/tls to generate cert.pem and key.pem.
    // ListenAndServeTLS always returns a non-nil error.
    err := http.ListenAndServeTLS(":10443", "cert.pem", "key.pem", nil)
    log.Fatal(err)
}
