go-从html中读取img的src

从html中读取img的src，剩下的交给迅雷

package main

import (

    "fmt"

    "github.com/PuerkitoBio/goquery"

    "io/ioutil"

    "log"

    "strings"

)

func main() {

    dat, err := ioutil.ReadFile("jkf.html")

    r := strings.NewReader(string(dat))

    doc, err := goquery.NewDocumentFromReader(r)

    if err != nil {

        log.Fatal(err)

    }

    doc.Find("img").Each(func(i int, s *goquery.Selection) {

        src, _ := s.Attr("src")

        fmt.Printf("%s\n", src)

    })

}
