Use grpc gateway to create rest API whose body is a list

[ganeshdipdumbare]

📚 Documentation

I am not able to find documentation as well as any example in case I want to accept list in the body of rest api as follows -
[ { "email": "Hello" }, { "email": "Hello" } ]

I am not sure if it is possible to create proto message to have such a rest api. Please let me know if it is not possible as I am working with api call where 3rd party caller is sending array directly as above.

Lists at the top level will probably require you to use google.protobuf.ListValue as request type. See https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/struct.proto for these types. They have special case handling in the gateway marshaler. I speak briefly about the special case handling of the well known types in my GopherCon UK 2019 talk: https://www.youtube.com/watch?v=Pq1paKC-fXk.

If you need more assistance, please reach out on the #grpc-gateway support channel on Gophers slack.
