C++ Protobuf to/from JSON conversion [closed]

问题:

Is anyone familiar with a stable C++ solution (library, code snippet etc.) which converts protobuf messages to/from JSON?

回答1:

This one is better IMO: https://github.com/shramov/json2pb

it does conversion in both directions and handles extensions

回答2:

I've made a bootstrap implementation of a JSON parser for protobuf generated types, using the its reflection mechanism, and adapting the parse I've made previously for CORBA IDL generated types.

You can find it at http://corbasim.googlecode.com/svn/trunk/protobuf2json_exported.zip

By this way for each protobuf defined message, you will be able to parse its instances by doing:

Foo foo;

const std::string json_foo = "{\"text\": \"Hello world\"}";

protobuf2json::json::parse(foo, json_foo);

It's just an initial implementation, and it just support string fields, but it's easy to implement all kind of fields.

pbjson is another one, which built on rapidjson, maybe faster.

回答4:

pb2json is another C++ library that can do this.
