在ClientInterceptor上使用grpc-java在元数据中包含消息哈希吗？

import io.grpc.*;

public class MessageHashInterceptor implements ClientInterceptor {
    private String messageHash;

    public MessageHashInterceptor(String messageHash) {
        this.messageHash = messageHash;
    }

    @Override
    public <ReqT, RespT> ClientCall<ReqT, RespT> interceptCall(
            MethodDescriptor<ReqT, RespT> method,
            CallOptions callOptions,
            Channel next) {
        Metadata metadata = new Metadata();
        metadata.put(Metadata.Key.of("message-hash", Metadata.ASCII_STRING_MARSHALLER), messageHash);

        return next.newCall(method, callOptions.withoutWaitForReady()).start(
                new ClientCall.Listener<RespT>() {
                    // Override listener methods if needed
                }, metadata);
    }
}
