下面的代码在hello world的基础上,使用ioutil库做文件操作也能实现基础的服务了。
package main
import (
"fmt"
"net/http"
"io/ioutil"
)
func handler(w http.ResponseWriter, r *http.Request) {
contents, err := ioutil.ReadFile(r.URL.Path[1:])
if err != nil {
fmt.Fprintf(w, "404")
return
}
fmt.Fprintf(w, "%s!\n", contents)
}
func main() {
http.HandleFunc("/", handler)
http.ListenAndServe(":8080", nil)
}
import (
"fmt"
"net/http"
"io/ioutil"
)
func handler(w http.ResponseWriter, r *http.Request) {
contents, err := ioutil.ReadFile(r.URL.Path[1:])
if err != nil {
fmt.Fprintf(w, "404")
return
}
fmt.Fprintf(w, "%s!\n", contents)
}
func main() {
http.HandleFunc("/", handler)
http.ListenAndServe(":8080", nil)
}
