golang中如何使用http长链接（client端）

package main



import (

        "fmt"

        "io"

        "log"

        "net/http"

)



func main() {

        request, err := http.NewRequest("GET", "http://www.example.com/", nil)

        if err != nil {

                log.Fatal(err)

        }



        http_client := &http.Client{}

        response, err := http_client.Do(request)

        if err != nil {

                log.Fatal(err)

        }



        buf := make([]byte, 4096) // any non zero value will do, try '1'.

        for {

                n, err := response.Body.Read(buf)

                if n == 0 && err != nil { // simplified

                        break

                }



                fmt.Printf("%s", buf[:n]) // no need to convert to string here

        }

        fmt.Println()

}
