go通过编码缩短字符串的长度实现方法步骤

package main

import (
"fmt"
"math/big"
)

// DecimalToHexadecimal 将十进制字符串转换为十六进制字符串
func DecimalToHexadecimal(decimalString string) (string, error) {
decimalBigInt := new(big.Int)
_, ok := decimalBigInt.SetString(decimalString, 10)
if !ok {
return "", fmt.Errorf("无效的十进制字符串")
}

return decimalBigInt.Text(16), nil
}

func main() {
decimalString := "1091108850771175743505511773475768112554397104776811510987102671075169102571117911978781114812210010067656897545178757189878312082485784116897512173"
hexString, err := DecimalToHexadecimal(decimalString)
if err != nil {
fmt.Println(err)
return
}
fmt.Println("十六进制字符串:", hexString)
}

// HexadecimalToDecimal 将十六进制字符串转换为十进制字符串
func HexadecimalToDecimal(hexString string) (string, error) {
    hexBigInt := new(big.Int)
    _, ok := hexBigInt.SetString(hexString, 16)
    if !ok {
        return "", fmt.Errorf("无效的十六进制字符串")
    }

    return hexBigInt.Text(10), nil
}

func main() {
    // 假设这是之前转换得到的十六进制字符串
    hexString := "e3a5a9d0d99c18aa3a3b5c4b75b8c1e5cd3cd999c05e2a1f48fa"
    decimalString, err := HexadecimalToDecimal(hexString)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println("还原的十进制字符串:", decimalString)
}
