Golang：来自URL的Json作为地图

Question

What is the best way to extract json from a url i.e. Rest service from Go? Also it seems most rest client libraries in go force a use of the json.marshall which needs a struct to be used with it.

This doesn't work in the case of unstructured data where you don't fully know what will be coming in. Is there a way to have it all simply come in as a map[string:string]?

Answer 1

Why not to parse it into map[string]string as this code have to do

var d map[string]interface{}
data, err := json.Unmarshal(apiResponse, &d)

You can traverse data in this struct too.

If you suspect, that api response can be not singular object, but the collection of objects, the interface{} also works for arrays.
