看到有很多python 的，然后写了个go 的，可以抓取高清图片
? getp.go
复制代码 代码如下:
package main
import (
??? "io/ioutil"
??? "log"
??? "net/http"
??? "os"
??? "regexp"
??? "strconv"
??? "strings"
??? "sync"
)
var urlist [4]string
var album chan string
var w sync.WaitGroup
var dir string
func main() {
??? dir = "tmp/"
??? err := os.Mkdir(dir, 0777)
??? if err != nil {
??????? isexist := os.IsExist(err)
??????? log.Println(isexist)
??? }
??? album = make(chan string, 200)
??? urlist = [4]string{"http://me2-sex.lofter测试数据/tag/%E7%BE%8E%E5%A5%B3%E6%91%84%E5%BD%B1?page=", "http://me2-sex.lofter测试数据/tag/%E6%AC%A7%E7%BE%8E?page=", "http://me2-sex.lofter测试数据/tag/%E6%A8%A1%E7%89%B9?page=", "http://me2-sex.lofter测试数据/tag/%E7%BE%8E%E5%AA%9B%E9%A6%86?page="}
??? for _, v := range urlist {

??????????? url := v + strconv.Itoa(i)
??????????? w.Add(1)
??????????? go GetAlbum(url)
??????????? w.Wait()
??????? }

}
func GetAlbum(url string) {
??? data := GetUrl(url)
