boost::asio::ip::address_v6是一个表示IPv6地址的类。要将它转换为两个uint64_t编号,可以使用以下方法:
要将两个uint64_t编号转换回IPv6地址,可以按照以下步骤进行:
下面是一个示例代码,演示了如何将boost::asio::ip::address_v6 IP转换为两个uint64_t编号,并将两个uint64_t编号转换回v6地址:
#include <boost/asio/ip/address_v6.hpp>
#include <iostream>
void convertIPv6ToUint64(const boost::asio::ip::address_v6& ipv6, uint64_t& part1, uint64_t& part2) {
const auto& addr = ipv6.to_bytes();
part1 = (static_cast<uint64_t>(addr[0]) << 48) | (static_cast<uint64_t>(addr[1]) << 32) |
(static_cast<uint64_t>(addr[2]) << 16) | static_cast<uint64_t>(addr[3]);
part2 = (static_cast<uint64_t>(addr[4]) << 48) | (static_cast<uint64_t>(addr[5]) << 32) |
(static_cast<uint64_t>(addr[6]) << 16) | static_cast<uint64_t>(addr[7]);
}
void convertUint64ToIPv6(uint64_t part1, uint64_t part2, boost::asio::ip::address_v6& ipv6) {
boost::asio::ip::address_v6::bytes_type addr;
addr[0] = static_cast<uint8_t>((part1 >> 48) & 0xFF);
addr[1] = static_cast<uint8_t>((part1 >> 32) & 0xFF);
addr[2] = static_cast<uint8_t>((part1 >> 16) & 0xFF);
addr[3] = static_cast<uint8_t>(part1 & 0xFF);
addr[4] = static_cast<uint8_t>((part2 >> 48) & 0xFF);
addr[5] = static_cast<uint8_t>((part2 >> 32) & 0xFF);
addr[6] = static_cast<uint8_t>((part2 >> 16) & 0xFF);
addr[7] = static_cast<uint8_t>(part2 & 0xFF);
ipv6 = boost::asio::ip::address_v6(addr);
}
int main() {
boost::asio::ip::address_v6 ipv6 = boost::asio::ip::address_v6::from_string("2001:db8::1");
uint64_t part1, part2;
convertIPv6ToUint64(ipv6, part1, part2);
std::cout << "Part 1: " << part1 << std::endl;
std::cout << "Part 2: " << part2 << std::endl;
boost::asio::ip::address_v6 convertedIPv6;
convertUint64ToIPv6(part1, part2, convertedIPv6);
std::cout << "Converted IPv6: " << convertedIPv6.to_string() << std::endl;
return 0;
}
请注意,这只是一个示例代码,用于演示如何进行转换。在实际应用中,你可能需要添加错误处理和边界检查来确保转换的正确性和安全性。
