go一个简单的爬虫，豆瓣

最近在学习go语言爬虫，写了个小demo

package main

import (
        "fmt"
        "io/ioutil"
        "net/http"
        "regexp"
        "strconv"
)

type Movie struct {
        name   string
        mark   string
        person string
        time   string
        url    string
}

func main() {
        chs := make([] chan int, 10)
        sliceList := []int{1291841,26761416,1309220,1300741,1293172}
        for i,v:=range sliceList{
                go child(v, chs[i])
        }
        for _, ch := range chs {
                <-ch
        }
}

func child(id int, ch chan int) {
        url := "https://movie.douban.com/subject/" + strconv.Itoa(id) + "/"
        resp, err := http.Get(url)
        if err != nil {
                panic(err)
        }
        defer resp.Body.Close()
        sHtml, _ := ioutil.ReadAll(resp.Body)

        movie := new(Movie)

        movie.name = GetValue(`<span\s*property="v:itemreviewed">(.*)</span>`, &sHtml)
        movie.mark = GetValue(`<strong\s*class="ll\s*rating_num"\s*property="v:average">(.*)</strong>`, &sHtml)
        movie.person = GetValue(`<a href="/celebrity/[0-9]+/" rel="v:directedBy">(.*)</a>`, &sHtml)
        movie.time = GetValue(`<span property="v:runtime" content="(.*)">.*</span>`, &sHtml)
        movie.url = GetValue(`<a href="(.*)" target="_blank" rel="nofollow">.*</a>`, &sHtml)

        fmt.Println(movie)

        ch <- 1
}

func GetValue(rule string, sHtml *[] byte) string {
        reg := regexp.MustCompile(rule)
        result := reg.FindAllStringSubmatch(string(*sHtml), 1)
        return result[0][1]
}
