有些地方的栏目链接不按套路出牌，可以使用**ChannelFunc**自定义栏目
```
package main
import (
articleSpider "github.com/PeterYangs/article-spider/v3"
)
func main() {
f := articleSpider.Form{
Host: "https://www.shouyouzhijia.net",
ChannelFunc: func(form *articleSpider.Form) []string {
return []string{
"/xinwen_1/",
"/xinwen_2/",
"/xinwen_3/",
"/xinwen_4/",
"/xinwen_5/",
"/xinwen_6/",
"/xinwen_7/",
"/xinwen_8/",
"/xinwen_9/",
}
},
PageStart: 1,
Length: 3,
ListSelector: "body > div.main.newex.clearfix > div.LC_lef > div.lef_content > dl",
HrefSelector: " dd > h3 > a",
DetailFields: map[string]articleSpider.Field{
"title": {Types: articleSpider.Text, Selector: "body > div.Min-cent.W1200 > div.Min_L > div.Left_top > h1"},
},
}
s := articleSpider.NewSpider(f, articleSpider.Normal)
s.Start()
}
```
