Examples with DnsClient org.rx.net.dns.DnsClient used on opensource projects

Example 1 with DnsClient

use of org.rx.net.dns.DnsClient in project rxlib by RockyLOMO.

the class Sockets method injectNameService.

@SneakyThrows
public static void injectNameService(List<InetSocketAddress> nameServerList) {
    DnsClient client = CollectionUtils.isEmpty(nameServerList) ? DnsClient.inlandClient() : new DnsClient(nameServerList);
    nsLock.lock();
    try {
        if (nsClient == null) {
            Class<?> type = InetAddress.class;
            try {
                Field field = type.getDeclaredField("nameService");
                Reflects.setAccess(field);
                field.set(null, nsProxy(field.get(null), client));
            } catch (NoSuchFieldException e) {
                Field field = type.getDeclaredField("nameServices");
                Reflects.setAccess(field);
                List<Object> nsList = (List<Object>) field.get(null);
                nsList.set(0, nsProxy(nsList.get(0), client));
            }
        }
        nsClient = client;
    } finally {
        nsLock.unlock();
    }
}

Example 2 with DnsClient

the class SocksTester method dns.

    // 注入变更 InetAddress.getAllByName 内部查询dnsServer的地址，支持非53端口
    Sockets.injectNameService(Collections.singletonList(localNsEp));
    List<InetAddress> wanResult = DnsClient.inlandClient().resolveAll(host_devops);
