Dictionary 在cunston类型中使用interator属性

我在编写Go代码时，使用basemap[string]int创建了一个类型，我需要创建一个返回映射、反转键和值的方法。我开始编写代码，但无法迭代我创建的类型

到目前为止，我已经编写了以下代码：

package constants

type Month map[string]int;

// LongMonth is a relationship with string and date value (int)
var LongMonth = Month{
    "Janary":1,
    "February":2,
    "March":3,
    "April":4, 
    "May":5,
    "June": 6,
    "July": 7,
    "August": 8,
    "September": 9,
    "Octuber": 10,
    "Novenber": 11,
    "Decenber": 12,
}

// ShortMonth is a relationship with a resume string and date value (int)
var ShortMonth = Month{
    "Jan":1,
    "Feb":2,
    "Mar":3,
    "Apr":4, 
    "May":5,
    "Jun": 6,
    "Jul": 7,
    "Aug": 8,
    "Sep": 9,
    "Oct": 10,
    "Nov": 11,
    "Dec": 12,
}

func (m* Month) Reverse() map[int]string {
    n:=make(map[int]string);
    for k, v := range m {
        n[v] = k
    }
    return n
};
// LongMonthReverse is a relationship with string and date value (int)
// var LongMonthReverse = reverseMonth(LongMonth);
// ShortMonthReverse is a relationship with string and date value (int)
// var ShortMonthReverse = reverseMonth(ShortMonth);

---

我需要函数Reverse返回Reverse emonth。例如：month={Jan:1…”Dec:12}和month.Reverse（）返回{1:“Jan”…12:“Dec”}

您不能迭代指针，或者将

func（m*month）Reverse（）map[int]string

的方法接口更改为

func（m month）Reverse（）map[int]string

，或者您需要在

Reverse（）的内部使用
*m

您不能迭代指针，或者将
func（m*Month）Reverse（）map[int]string
的方法接口更改为
func（m Month）Reverse（）map[int]string
，或者您需要在
Reverse（）的内部使用
*m

您不能使用
m
作为范围的值，因为其类型是
*月份
。我建议将该方法的签名更改为
func（m Month）Reverse（）map[int]string
您不能将
m
用作范围的值，因为其类型为
*Month
。我建议将方法的签名更改为
func（m月）Reverse（）map[int]string
package main

import "fmt"


type Month map[string]int

// LongMonth is a relationship with string and date value (int)
var LongMonth = Month{
    "Janary":1,
    "February":2,
    "March":3,
    "April":4,
    "May":5,
    "June": 6,
    "July": 7,
    "August": 8,
    "September": 9,
    "Octuber": 10,
    "Novenber": 11,
    "Decenber": 12,
}

// ShortMonth is a relationship with a resume string and date value (int)
var ShortMonth = Month{
    "Jan":1,
    "Feb":2,
    "Mar":3,
    "Apr":4,
    "May":5,
    "Jun": 6,
    "Jul": 7,
    "Aug": 8,
    "Sep": 9,
    "Oct": 10,
    "Nov": 11,
    "Dec": 12,
}

func (m* Month) Reverse() map[int]string {
    n:=make(map[int]string)
    // this is the fix
    for k, v := range *m {
        n[v] = k
    }
    return n
}


func main() {
  fmt.Println(ShortMonth.Reverse())
}
