问题 I am struggling with deserializing a integer into a string struct field. The struct field is a string and is expected to be assignable from users of my library. That's why I want it to be a string, since for the purpose of writing it to the database I actually don't care about the value inside. The users can supply text, but some just assign integers. Consider this struct: type Test struct { Foo string } Sometimes I end up with a JSON value that is valid but won't deserialize into the struct

问题 If I create a "photo" without any tags it is stored in dynamodb as "tags": { "NULL": true }, But when I query and unmarshal the record I would expect that it converts this into an empty slice instead I get this: [{"photo_id":"bmpuh3jg","tags":null}] Is it possible to have it convert it into an empty slice instead? e.g. [{"photo_id":"bmpuh3jg","tags":[]}] CODE EXAMPLE My struct type Photo struct { Id string `json:"photo_id"` Tags []string `json:"tags"` } Query photo := &Photo{} input :=
