像这种文本里面带【多图】的,想要把这种后缀去掉可以用**ConversionFunc**
```
package main
import (
articleSpider "github.com/PeterYangs/article-spider/v3"
"strings"
)
func main() {
f := articleSpider.Form{
Host: "https://www.shouyouzhijia.net",
Channel: "/xinwen_[PAGE]/",
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", ConversionFunc: func(data string, resList map[string]string) string {
return strings.Replace(data, "[多图]", "", -1)
}},
},
}
s := articleSpider.NewSpider(f, articleSpider.Normal)
s.Start()
}
```
>[info]**ConversionFunc** 第一个参数是当前字段的结果，第二个参数是所有字段的结果map
