基於golang的手機號碼簡易爬蟲

 百度一下手機號碼，隨便進一個網址。利用正則表達式獲取這個網址的所有手機號碼

package main

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

var (
	Phonenumber = `1[3456789]\d{9}`
)

func HandleError(err error, when string) {
	if err != nil {
		fmt.Println(when, err)
		os.Exit(1)
	}
}
func main() {
	resp, err := http.Get("http://www.gdhaoma.com/others/haoduans.asp?haoma=1316178")
	HandleError(err, "http://www.gdhaoma.com/others/haoduans.asp?haoma=1316178")
	bytes, _ := ioutil.ReadAll(resp.Body)
	html := string(bytes)
	//fmt.Println(html)

	re := regexp.MustCompile(Phonenumber)
	allString := re.FindAllStringSubmatch(html, -1)
	fmt.Println(allString)

}
