如何在Lua中将IPv6地址解析成字节数组？

local socket = require("socket")

-- 定义IPv6地址
local ipv6Address = "2001:0db8:85a3:0000:0000:8a2e:0370:7334"

-- 使用socket库的inet_pton函数将IPv6地址解析成字节数组
local function ipv6ToByteArray(ipv6)
  local bytes = {}
  local parts = {ipv6:match("([a-fA-F0-9]+):")}
  local doubleColonIndex = ipv6:find("::")

  if doubleColonIndex then
    local firstPart = ipv6:sub(1, doubleColonIndex - 1)
    local secondPart = ipv6:sub(doubleColonIndex + 2)

    local firstParts = {firstPart:match("([a-fA-F0-9]+):")}
    local secondParts = {secondPart:match("([a-fA-F0-9]+):")}

    for i = 1, #firstParts do
      bytes[#bytes + 1] = tonumber(firstParts[i], 16) // 256
      bytes[#bytes + 1] = tonumber(firstParts[i], 16) % 256
    end

    local missingParts = 8 - (#firstParts + #secondParts)

    for i = 1, missingParts do
      bytes[#bytes + 1] = 0
      bytes[#bytes + 1] = 0
    end

    for i = 1, #secondParts do
      bytes[#bytes + 1] = tonumber(secondParts[i], 16) // 256
      bytes[#bytes + 1] = tonumber(secondParts[i], 16) % 256
    end
  else
    for i = 1, #parts do
      bytes[#bytes + 1] = tonumber(parts[i], 16) // 256
      bytes[#bytes + 1] = tonumber(parts[i], 16) % 256
    end
  end

  return bytes
end

-- 调用函数将IPv6地址解析成字节数组
local byteArray = ipv6ToByteArray(ipv6Address)

-- 打印字节数组
for i = 1, #byteArray do
  print(byteArray[i])
end
