When I use an interceptor to authenticate clients (in bi-directional
streaming scenarios), if unauthenticated clients refuse to shutdown their
channels, how can I forcefully close connections and reclaim opened file
descriptors?
Here's the code for the interceptor (assuming that I reject all gRPC calls)
and it doesn't work.
@Overridepublic <ReqT, RespT> ServerCall.Listener<ReqT> interceptCall(
ServerCall<ReqT, RespT> call,
final Metadata requestHeaders,
ServerCallHandler<ReqT, RespT> next) {
call.close(Status.CANCELLED, requestHeaders);
return new ServerCall.Listener() {
};
}
