代码如下：
import (
"math"
)
type Page struct {
CurrentPage int64 //当前页码
PageSize int64 //每页条数
TotalPage int64 //总条数
Nums []int64 //分页序数
PageCount int64 //总页数
}
func (_ Page) CreatePage(currentPage, pageSize, total int64) Page {
if currentPage < 1 {
currentPage = 1
}
if pageSize < 1 {
pageSize = 1
}
this := Page{}
this.CurrentPage = currentPage
this.PageSize = pageSize
this.TotalPage = total
this.PageCount = int64(math.Ceil((float64(total)) / float64(pageSize)))
this.setNum()
return this
}
//设置序号
func (this *Page) setNum() {
this.Nums = []int64{}
if this.PageCount == 0 {
return
}
var begin int64 = 1
var end int64 = 5
if this.PageCount <= 5 {
end = this.PageCount
} else {
begin = this.CurrentPage - 2
end = this.CurrentPage + 2
if begin <= 0 {

end = 5
}
if end >= this.PageCount {

}
}
for i := begin; i <= end; i++ {

}
