03/23/2023, 9:36 AMHi. I am trying to find a way to mock protobuf response. I have a json mapping. Want to convert that as protobuf response.
Wondering if wiremock supports that

@Tom Looks like custom matcher is for extensive use. Like if we are looking for something specific in request . However, my requirement is simple: I just look for the URI and header tag. If it matches then it need to return the response back as a protobuf
So, would I still need custom matcher for this?

You’d need to encode the protobuf as base64 then return it as a binary response

__files Copy code
{
"request": {
"method": "POST",
"url": "/proto"
},
"response": {
"status": 200,
"bodyFileName": "my-data.proto" // The name of the file under __files
}

04/01/2023, 8:11 AM@Tom I tried use the suggested way, and I see exception on client side when I deserialize 'EntityResponse response = response.getEntity(EntityResponse.class)'
com.google.protobuf.InvalidProtocolBufferException$InvalidWireTypeException: Protocol message tag had invalid wire type.
The message is encoded and sent as binary. Not sure what am I missing here
