在 GoLang 中对自定义 struct 体数组进行排序

你可以用sort.Slice美元买那个.它接受您的切片和排序函数. 排序函数本身接受两个索引，如果左边的条目是smaller而右边的条目是smaller，则返回TRUE.

这样，您就可以根据自己的自定义标准进行排序.

package main

import (
    "fmt"
    "sort"
)

type TicketDistribution struct {
    Label        string
    TicketVolume int64
}

type TicketDistributionResponse struct {
    LevelDistribution []*TicketDistribution
}

func main() {
    var response TicketDistributionResponse

    response.LevelDistribution = append(response.LevelDistribution, &TicketDistribution{Label: "John", TicketVolume: 3})
    response.LevelDistribution = append(response.LevelDistribution, &TicketDistribution{Label: "Bill", TicketVolume: 7})
    response.LevelDistribution = append(response.LevelDistribution, &TicketDistribution{Label: "Sam", TicketVolume: 4})

    sort.Slice(response.LevelDistribution, func(i, j int) bool {
        a := response.LevelDistribution[i]
        b := response.LevelDistribution[j]
        return a.TicketVolume > b.TicketVolume
    })

    for _, val := range response.LevelDistribution {
        fmt.Println(*val)
    }
}

在比较函数中使用>对切片进行降序排序，对于升序，您将使用<.
