Golang高并发抓取HTML图片

Golang高并发抓取HTML图片

使用准备

1.安装Golang

2.下载爬虫包

go get -v github.com/hunterhug/marmot/util
go get -v github.com/hunterhug/marmot/tool

程序

该程序只能抓取HTML中src="http"中的图片, 必须带有协议头http(s), 其他如data-src和混淆在JS中的无法抓取

See: https://github.com/hunterhug/marmot/blob/master/example/practice/pictures/main.go

package main

import (
	"fmt"
	"github.com/hunterhug/marmot/util"
	"github.com/hunterhug/marmot/tool"
)

// Num of miner, We can run it at the same time to crawl data fast
var MinerNum = 5

// You can update this decide whether to proxy
var ProxyAddress interface{}

func main() {
	// You can Proxy!
	// ProxyAddress = "socks5://127.0.0.1:1080"

	fmt.Println(`Welcome: Input "url" and picture keep "dir"`)
	fmt.Println("---------------------------------------------")
	url := util.Input(`URL(Like: "http://publicdomainarchive.com")`, "http://publicdomainarchive.com")
	dir := util.Input(`DIR(Default: "./picture")`, "./picture")
	fmt.Printf("You will keep %s picture in dir %s\n", url, dir)
	fmt.Println("---------------------------------------------")

	// Start Catch
	err := tool.DownloadHTMLPictures(url, dir, MinerNum, ProxyAddress)
	if err != nil {
		fmt.Println("Error:" + err.Error())
	}
}

解释均写, 运行后:

Welcome: Input "url" and picture keep "dir"

---------------------------------------------
URL(Like: "http://publicdomainarchive.com")

DIR(Default: "./picture")

You will keep http://publicdomainarchive.com picture in dir ./picture
