java.net.SocketAddress . This class performs network requests to resolve address names,
and should only be used in places that are expected to do IO such as the
io.grpc.NameResolver .
In order for gRPC to use a proxy, NameResolver, ProxyDetector and the
underlying transport need to work together.
The NameResolver should invoke the ProxyDetector retrieved from the NameResolver., and pass the returned ProxiedSocketAddress to
NameResolver.. The DNS name resolver shipped with gRPC is already
doing so.
The default ProxyDetector uses Java's standard java. and
java. to detect proxies and authentication credentials and produce
HttpConnectProxiedSocketAddress, which is for using an HTTP CONNECT proxy. A custom
ProxyDetector can be passed to ManagedChannelBuilder#proxyDetector.
The ProxiedSocketAddress is then handled by the transport. The transport needs to
support whatever type of ProxiedSocketAddress returned by ProxyDetector. The
Netty transport and the OkHttp transport currently only support HttpConnectProxiedSocketAddress which is returned by the default ProxyDetector.
