如何获取Mongo文档并将其作为JSON API响应返回

I'm writing an API which retrieves Mongo documents and return those documents as a JSON response.

I can certainly do this by creating a struct with the proper field mappings, but since i'm not processing these documents, I simply want to convert the raw data I get from the code below to JSON. My API will then return the JSON as a response.

I have the following code:

var raw []bson.Raw
err = myCollection.Find(
      bson.M{"name": name},
).All(&raw)

I want to convert raw to JSON. How would I do that? Is there a better of this this other than by starting to create a bson.Raw?

Tech stack:
Go 1.1
mgo v1  http://godoc.org/labix.org/v1/mgo
bson v1 http://godoc.org/labix.org/v1/mgo/bson

Thanks.

Unmarshal it into maps instead:

var maps []bson.M
err = myCollection.Find(bson.M{"name": name}).All(&maps)

This way you can provide these same maps to the encoding/json package's Marshal function.
