获取网卡信息

要获取网卡信息,可以使用Boost库的asio和system模块。以下是一个示例代码,可以获取网卡名称、MAC地址和IP地址:
```c++
#include <boost/asio.hpp>
#include <boost/system/error_code.hpp>
#include <boost/asio/ip/address.hpp>
#include <boost/asio/ip/network_v4.hpp>
#include <boost/asio/ip/network_v6.hpp>
#include <iostream>
using namespace boost::asio;
int main()
{
io_service io;
boost::system::error_code ec;
// 获取所有网卡信息
ip::tcp::resolver resolver(io);
ip::tcp::resolver::query query(host_name(), "");
ip::tcp::resolver::iterator iter = resolver.resolve(query, ec);
if (ec) {
std::cerr << "Error: " << ec.message() << std::endl;
return 1;
}
// 循环遍历每个网卡
for (; iter != ip::tcp::resolver::iterator(); ++iter) {
ip::address addr = iter->endpoint().address();
// 忽略非IPv4和IPv6地址
if (addr.is_v4() || addr.is_v6()) {
std::cout << "Interface: " << iter->interface_name() << std::endl;
std::cout << "MAC Address: " << addr.to_string() << std::endl;
// 获取IP地址
if (addr.is_v4()) {
ip::address_v4::bytes_type ipv4_bytes = addr.to_v4().to_bytes();
ip::network_v4 network(ipv4_bytes, ip::address_v4::netmask(ec));
if (ec) {
std::cerr << "Error: " << ec.message() << std::endl;
return 1;
}
std::cout << "IP Address: " << network.address().to_string() << std::endl;
}
else {
ip::address_v6::bytes_type ipv6_bytes = addr.to_v6().to_bytes();
ip::network_v6 network(ipv6_bytes, ip::address_v6::prefix_length(ec));
if (ec) {
std::cerr << "Error: " << ec.message() << std::endl;
return 1;
}
std::cout << "IP Address: " << network.address().to_string() << std::endl;
}
std::cout << std::endl;
}
}
return 0;
}
```
在上面的代码中,我们使用了`ip::tcp::resolver`类来获取所有网卡的信息。然后,我们循环遍历每个网卡,获取其名称、MAC地址和IP地址。获取IPv4地址时,我们还使用了`ip::network_v4`类来计算子网掩码,从而得到IP地址。获取IPv6地址时,我们使用了`ip::network_v6`类来计算前缀长度,从而得到IP地址。
