有的网站会根据 User-Agent 的不同,跳转到不同(PC、M)的站点,也有根据版本的不同给出不一样的提示等等,而 User-Agent 的变化更是爬虫里的基础姿势
使用 Go 编写网络爬虫或需要模拟浏览器头(User-Agent)的时候,你是否会觉得很麻烦,获取请求头(Request Headers)的 User-Agent 还得找来找去,挺繁琐。先前我也遇到了这个问题,因此有了这个项目 fake-useragent,用来解决你我的痛点
$ go get github.com/EDDYCJY/fake-useragent
package main
import (
"log"
"github.com/EDDYCJY/fake-useragent"
)
func main() {
