Netty Http Client -配置DNSResolution超时

Question

我得到这个错误与WebClient。根据我的配置，这是预期的。但是如何通过netty http客户端配置dns名称解析的超时?

Caused by: io.netty.resolver.dns.DnsNameResolverTimeoutException: [/127.0.0.11:53] query via UDP timed out after 5000 milliseconds (no stack trace available)

Answer 1

默认情况下，DNS查询超时时间为5秒(DEFAULT_QUERY_TIMEOUT)，但如果需要，您可以自定义下划线NettyHttpClient

HttpClient httpClient = HttpClient.create()
.resolver(spec -> spec.queryTimeout(Duration.ofSeconds(10)));
WebClient client = WebClient.builder()
.clientConnector(new ReactorClientHttpConnector(httpClient))
.build();
