NetCore Grpc拦截

客户端拦截：

    public class ClientLoggerInterceptor : Interceptor
    {
        public override AsyncUnaryCall<TResponse> AsyncUnaryCall<TRequest, TResponse>(
            TRequest request,
            ClientInterceptorContext<TRequest, TResponse> context,
            AsyncUnaryCallContinuation<TRequest, TResponse> continuation)
        {
            var requestStr = request.ToString();
            var requestMethod = context.Method;
            var response = continuation(request, context);
            return response;
        }


        public override AsyncServerStreamingCall<TResponse> AsyncServerStreamingCall<TRequest, TResponse>(TRequest request, ClientInterceptorContext<TRequest, TResponse> context, AsyncServerStreamingCallContinuation<TRequest, TResponse> continuation)
        {
            var requestStr = request.ToString();
            var requestMethod = context.Method;
            var call = base.AsyncServerStreamingCall(request, context, continuation);
            return call;
        }
    }

客户端拦截器注册：

services.AddGrpcClient<T>(options =>
{
    options.InterceptorRegistrations.Add(new Grpc.Net.ClientFactory.InterceptorRegistration(InterceptorScope.Client, s => new ClientLoggerInterceptor()));
});

服务端：

public class ServerLoggerInterceptor: Interceptor
{

    public override Task<TResponse> UnaryServerHandler<TRequest, TResponse>(
        TRequest request,
        ServerCallContext context,
        UnaryServerMethod<TRequest, TResponse> continuation)
    {
          var requestStr = request.ToString();
		  var requestMethod = context.Method;
		  var response = continuation(request, context);
		  return response;
    }
}
