Golang Colly Scraping - Website Captcha Catches My Scrape

问题

我为亚马逊产品标题做了爬取,但是亚马逊的验证码抓住了我的爬虫。我尝试了10次运行main.go(8次被抓住,2次成功爬取了产品标题)。

我进行了研究,但没有找到针对golang的解决方案(只有Python的解决方案),是否有适用于我的解决方案?

package main

import (
	"fmt"
	"strings"

	"github.com/gocolly/colly"
)

func main() {

	// 创建一个专门用于 Shopify 的 Collector
	c := colly.NewCollector(
		colly.AllowedDomains("www.amazon.com", "amazon.com"),
	)
	c.OnHTML("div", func(h *colly.HTMLElement) {
		capctha := h.Text
		title := h.ChildText("span#productTitle")
		fmt.Println(strings.TrimSpace(title))
		fmt.Println(strings.TrimSpace(capctha))
	})

	// 启动 Collector
	c.Visit("https://www.amazon.com/Bluetooth-Over-Ear-Headphones-Foldable-Prolonged/dp/B07K5214NZ")
}

I did make Scraping for Amazon Product Titles but Amazon captcha catches my scraper. I tried 10 times- go run main.go(8 times catches me - 2 times I scraped the product title)

I researched this but I did not find any solution for golang(there is just python) is there any solution for me?


package main

import (
	"fmt"
	"strings"0

	"github.com/gocolly/colly"
)

func main() {

	// Create a Collector specifically for Shopify
	c := colly.NewCollector(
		colly.AllowedDomains("www.amazon.com", "amazon.com"),
	)
	c.OnHTML("div", func(h *colly.HTMLElement) {
		capctha := h.Text
		title := h.ChildText("span#productTitle")
		fmt.Println(strings.TrimSpace(title))
		fmt.Println(strings.TrimSpace(capctha))
	})

	// Start the collector
	c.Visit("https://www.amazon.com/Bluetooth-Over-Ear-Headphones-Foldable-Prolonged/dp/B07K5214NZ")
}

如果您不介意使用不同的软件包,我写了一个用于搜索HTML的软件包(实际上是github.com/tdewolff/parse的薄包装):

package main

import (
   "github.com/89z/parse/html"
   "net/http"
   "os"
)

func main() {
   req, err := http.NewRequest(
      "GET", "https://www.amazon.com/dp/B07K5214NZ", nil,
   )
   req.Header = http.Header{
      "User-Agent": {"Mozilla"},
   }
   res, err := new(http.Transport).RoundTrip(req)
   if err != nil {
      panic(err)
   }
   defer res.Body.Close()
   lex := html.NewLexer(res.Body)
   lex.NextAttr("id", "productTitle")
   os.Stdout.Write(lex.Bytes())
}

结果:

Bluetooth Headphones Over-Ear, Zihnic Foldable Wireless and Wired Stereo
Headset Micro SD/TF, FM for Cell Phone,PC,Soft Earmuffs &Light Weight for
Prolonged Waring(Rose Gold)

If you don't mind a different package, I wrote a package to search HTML
(essentially thin wrapper around github.com/tdewolff/parse):

package main

import (
   "github.com/89z/parse/html"
   "net/http"
   "os"
)

func main() {
   req, err := http.NewRequest(
      "GET", "https://www.amazon.com/dp/B07K5214NZ", nil,
   )
   req.Header = http.Header{
      "User-Agent": {"Mozilla"},
   }
   res, err := new(http.Transport).RoundTrip(req)
   if err != nil {
      panic(err)
   }
   defer res.Body.Close()
   lex := html.NewLexer(res.Body)
   lex.NextAttr("id", "productTitle")
   os.Stdout.Write(lex.Bytes())
}

Result:

Bluetooth Headphones Over-Ear, Zihnic Foldable Wireless and Wired Stereo
Headset Micro SD/TF, FM for Cell Phone,PC,Soft Earmuffs &Light Weight for
Prolonged Waring(Rose Gold)
