I’m trying to implement Any, including proper JSON and protobuf encoding, and the following scenario has me stumped:
Consider the following example from the google/protobuf/any.proto source file: Sample proto file: // package google.profile; // message Person { // string first_name = 1; // string last_name = 2; // } Resulting JSON encoding: // { // "@type": "type.googleapis.com/google.profile.Person", // "firstName": <string>, // "lastName": <string> // } The scenario I’m trying to understand involves three systems: Originating system: * Knows google.profile and writes out the JSON above Middle system: * Reads the JSON example above * Does *not* know google.profile (doesn’t have the descriptor and has no way to get it) * Writes out protobuf Receiving system: * Knows google.profile and reads the protobuf In particular: What is the protobuf serialization between the middle and receiving systems? Without the descriptor, the middle system cannot poduce the “real" protobuf binary format (it doesn't have the field numbers), so the only option would seem to be to serialize the JSON data as a protobuf Struct, which would have interesting implications for the receiving system. Am I missing some other option? Tim P.S. Nice work on the conformance test suite, by the way! That answered a *lot* of questions about the expected handling for protobuf JSON format. -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
