Collyzar - A distributed redis-based framework for colly.

Overview

Collyzar

A distributed redis-based framework for colly.

Collyzar provides a very simple configuration and tools to implement distributed crawling/scraping.

Features

  • Simple configuration and clean API
  • Distributed crawling/scraping
  • Built-in global bloom filter
  • Built-in spider cache
  • Support redis command
  • Multi-machine load balancing
  • Support to pause or stop all crawling machines
  • Pass additional information to the crawler and get it inside the crawler and store it in the database

Installation

Add collyzar to your go.mod file:

module github.com/x/y

go 1.14

require (
        github.com/Zartenc/collyzar/v2 latest
)

Example Usage

See examples folder for more detailed examples.

Crawler cluster machine

SpiderName must be unique.

After running, it will always monitor the redis crawler queue for crawling until it receives a pause or stop signal.

func main(){
    cs := &collyzar.CollyzarSettings{
    		SpiderName: "zarten",
    		Domain:     "www.amazon.com",
    		RedisIp:    "127.0.0.1",
    	}
	collyzar.Run(myResponse, cs, nil)
}

func myResponse(response *collyzar.ZarResponse){
	fmt.Println(response.StatusCode)
}

Control machine

Push url to redis queue

func main(){
	ts := collyzar.NewToolSpider("127.0.0.1", 6379, "", "zarten")

	url := "https://www.amazon.com"
	pushInfo := collyzar.PushInfo{Url:url}

	err := ts.PushToQueue(pushInfo)
	if err != nil{
		fmt.Println(err)
	}
}

Tools

Provide tools including stop crawlers and pause crawlers.

Stop all crawlers
func main() {
	ts := collyzar.NewToolSpider("127.0.0.1", 6379, "", "zarten")

	err := ts.StopSpiders()
	if err != nil{
		fmt.Println(err)
	}
}

Pause all crawlers

For all crawlers, the crawler process is idle after pausing the crawler.
Then you can use the WakeupSpiders method to wake up the crawlers.

func main() {
	ts := collyzar.NewToolSpider("127.0.0.1", 6379, "", "zarten")

	err := ts.PauseSpiders()
	if err != nil{
		fmt.Println(err)
	}
}
