如何验证带协议网络地址？

Question

我正试图用戈朗写一个钱包地址验证器。我为ATOM (宇宙)编写了验证器。波段网络也使用宇宙SDK。带网络和原子网络是相似的。

这是我写的宇宙钱包验证器的代码：

package atom_validator

import (
    "regexp"

    "github.com/btcsuite/btcutil/bech32"
)

const allowed_chars = "qpzry9x8gf2tvdw0s3jn54khce6mua7l"
const atomRegex = "^(cosmos)1([" + allowed_chars + "]+)$" // cosmos + bech32 separated by "1"

func IsValidAddress(address string) bool {
    match, _ := regexp.MatchString(atomRegex, address)
    if match {
        return verifyChecksum(address)
    } else {
        return false
    }
}

func verifyChecksum(address string) bool {
    _, decoded, _ := bech32.Decode(address)

    if decoded != nil {
        return len(decoded) == 32
    } else {
        return false
    }
}

我正在寻找一种方法来做同样的验证使用Golang乐队协议。谢谢。

我解决了问题。在regex字符串中将“原子”替换为"band“。

package band_validator


import (
    "regexp"

    "github.com/btcsuite/btcutil/bech32"
)

const allowed_chars = "qpzry9x8gf2tvdw0s3jn54khce6mua7l"
const atomRegex = "^(band)1([" + allowed_chars + "]+)$"

func IsValidAddress(address string) bool {
    match, _ := regexp.MatchString(atomRegex, address)
    if match {
        return verifyChecksum(address)
    } else {
        return false
    }
}

func verifyChecksum(address string) bool {
    _, decoded, _ := bech32.Decode(address)

    if decoded != nil {
        return len(decoded) == 32
    } else {
        return false
    }
}
