HTTP server

Context

Go’s net/http package makes it easy to build HTTP servers. Use http.HandleFunc and http.ListenAndServe.

Example

A simple server that responds with “Hello, World”.

Code example

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, %s!", r.URL.Path[1:])
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

Output (curl http://localhost:8080/Alice)

Hello, Alice!
