Go’s fake-UserAgent

Some websites will jump to different sites (PC and M) according to the difference of user-Agent, and also give different hints according to different versions, etc., while the change of User-Agent is the basic posture in crawler

Use Go to write web crawler or need to simulate the user-agent of the browser (Request Headers), do you feel very cumbersome, you have to find the user-agent of the Request Headers. I ran into this problem earlier, so I came up with fake-UserAgent to solve your and mine pain points

Project address: github.com/EDDYCJY/fak…

	"log"

	"github.com/EDDYCJY/fake-useragent"
)

func main(a) {
	// Recommended
	random := browser.Random()
	log.Printf("Random: %s", random)

	chrome := browser.Chrome()
	log.Printf("Chrome: %s", chrome)

	internetExplorer := browser.InternetExplorer()
	log.Printf("IE: %s", internetExplorer)

	firefox := browser.Firefox()
	log.Printf("Firefox: %s", firefox)

	safari := browser.Safari()
	log.Printf("Safari: %s", safari)

	android := browser.Android()
	log.Printf("Android: %s", android)

	macOSX := browser.MacOSX()
	log.Printf("MacOSX: %s", macOSX)

	ios := browser.IOS()
	log.Printf("IOS: %s", ios)

	linux := browser.Linux()
	log.Printf("Linux: %s", linux)

	iphone := browser.IPhone()
	log.Printf("IPhone: %s", iphone)

	ipad := browser.IPad()
	log.Printf("IPad: %s", ipad)

	computer := browser.Computer()
	log.Printf("Computer: %s", computer)

	mobile := browser.Mobile()
	log.Printf("Mobile: %s", mobile)
}
Copy the code

custom

You can adjust the maximum number of pages, time interval, and maximum timeout for fetching data sources. If no value is specified, the default value is used.

client := browser.Client{
	MaxPage: 3,
	Delay: 200 * time.Millisecond,
	Timeout: 10 * time.Second,
}
cache := browser.Cache{}
b := browser.NewBrowser(client, cache)

random := b.Random()
Copy the code

Update the browser header’s temporary file cache

client := browser.Client{}
cache := browser.Cache{
	UpdateFile: true,
}
b := browser.NewBrowser(client, cache)
Copy the code

Finally, the general usage is recommended, and the default parameters are sufficient for everyday use

Pay attention to

If used for the first time, fake-UserAgent will collect data and create a file in the temporary directory as a file cache, so be patient for a few seconds
