无法将类型* json.RawMessage的表达式转换为golang中的[] byte类型

Question

code and error message

I was experiencing this problem when using golang's elasticsearch client "elastic".

*json.RawMessage is a type of []byte.If I not write []byte() to cast type, it said cannot use 'resp.Source' (type *json.RawMessage) as type []byte.

The environment is go 1.10.3 and elastic 6.x

Answer 1

A *json.RawMesasge is not a []byte. It's a pointer.

Dereference the pointer to convert to a slice of bytes:

 byteSlice := []byte(*pointerToRawMessage)
