Looks to me like you can implement your own marshaler and use a custom content-type to support this. I don't think we'll add first class support for this. Please have a look at https://grpc-ecosystem.github.io/grpc-gateway/docs/customizingyourgateway.html for an example.

@johanbrandhorst the custom marshaler can only get the response message from handle, but the JSONP's response also need the callback function name from the url query. so how can I transfer the value from http.Request to the marshal graceful ?

[johanbrandhorst]

We don't currently have that capability, no, but there was some discussion around adding a ctx parameter to the marshaler for v2, so that things like per-method marshalling could be performed. Would you be interested in contributing something like this?

[t2krew]

yes, of course interested if I can, let me first understand your discussion about the second edition, and then try to do it.
