[protobuf] Re: Protobuf over HTTP
Thanks Marc, Just one more question. Can I use protobuf-net for RPC Services If Yes can these services be written and driven by WCF services, with WsHttpBinding or TCPBinding ???

Re: [protobuf] Re: Protobuf over HTTP
WCF can provide RPC, and protobuf-net can elbow it's way inside WCF *for some scenarios*. One option here is simply with some WCF configuration changes: http://marcgravell.blogspot.com/2009/11/controlling-wcf-protobuf-net-at.html It isn't specific to any particular binding - but works best for bindings that are happy with binary - my /preferred/ binding here is basicHttpBinding with MTOM enabled. But : any other RPC mechanism that allows binary transports should be usable in some way or another. At the simplest level, an HTTP post with a binary payload, or a simple socket server (if you are happy to wrap your own dispatcher on the end).

[protobuf] Encoding/Decoding extension
Hi,
I've done some experiment using protocol buffers extension but I kind
of wondering if I am doing things the right way. For the encoding I've
seen some explanation on the multi message encoding, and what I am
doing seems ok. On the other hand I am kind of suspicious about my
decoding routine.
my .proto file is pretty straightforward
message Message {
extensions 5 to max;
}
message Dummy {
optional float x = 1;
optional float y = 2;
}
message Foo {
optional int v = 1;
}
extend Message {
optional Dummy dummy = 5;
}
extend Message {
optional Foo foo = 50001;
}
My encoding code look like :
int fd = open(argv[1], O_CREAT|O_RDONLY|O_WRONLY);
google::protobuf::io::ZeroCopyOutputStream* raw_output = new
google::protobuf::io::FileOutputStream(fd);
google::protobuf::io::CodedOutputStream* coded_output = new
google::protobuf::io::CodedOutputStream(raw_output);
ns_message::Message message;
ns_message::Dummy* dummy =
message.MutableExtension(ns_message::dummy);
dummy-set_x(5);
int size = message.ByteSize();
coded_output-WriteVarint32(size);
message.SerializeToCodedStream(coded_output);
message.ClearExtension(ns_message::dummy);
ns_message::Foo* zoom = message.MutableExtension(csi_message::zoom);
[encoding the same way]
For the decoding here is what I am doing:
int fd = open(argv[1], O_RDONLY);
google::protobuf::io::ZeroCopyInputStream* raw_input = new
google::protobuf::io::FileInputStream(fd);
google::protobuf::io::CodedInputStream* coded_input = new
google::protobuf::io::CodedInputStream(raw_input);
ns_message::Message message;
google::protobuf::uint32 size;
while ( coded_input-ReadVarint32(size) ) {
int previous = coded_input-PushLimit(size);
message.ParseFromCodedStream(coded_input);
coded_input-PopLimit(previous);
std::vectorconst google::protobuf::FieldDescriptor* fields;
const google::protobuf::Reflection* reflection =
message.GetReflection();
reflection-ListFields(message, fields);
for (int i = 0; i fields.size(); ++i) {
if (fields[i]-is_extension()) {
getExtensionMessage(message, fields[i]);
}
}
}
getExtensionMessage doesn't do anything fancy for the moment
if(field-name() == dummy) {
csi_message::* Dummy = dummy.MutableExtension(ns_message::dummy);
print(*dummy);
}
Thanks in advance for your comments.
