一段解析M3u8预加载ts的go代码

package main

import "fmt"
import "net/http"
import "io/ioutil"
import "strings"
import "bufio"

func httpGet() {
resp, err := http.Get("")
if err != nil {
// handle error
}

defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
// handle error
}
src := string(body)
//fmt.Println(src)

sReader := strings.NewReader(string(src))
bReader := bufio.NewScanner(sReader)
bReader.Split(bufio.ScanLines)
for bReader.Scan() {
line := bReader.Text()
if !strings.HasPrefix(line, "#") {
tsFileName := line
fmt.Println(tsFileName)
tsFileUrl := fmt.Sprintf("%s", tsFileName)
fmt.Println(tsFileUrl)
downloadTS(tsFileUrl)
}
}
}

func downloadTS(tsFileUrl string) {
fmt.Println("downloading: ", tsFileUrl)
resp, err := http.Get(tsFileUrl)
if err != nil {
fmt.Println("download ts ", tsFileUrl, "failed,", err)
return
}
defer resp.Body.Close()
//fmt.Println(resp.Body)
}

func main() {
httpGet()
//fmt.Printf("hello, world\n")
}
