JSON数组封送处理

Question

I have a function that returns an interface{}. How can I serialize this into a JSON Array without "hardcoding" the fields in a struct. I am using https://github.com/jmoiron/jsonq to return the interface.

json.Unmarshal(resp.Bytes(), &response)
data := map[string]interface{}{}
dec := json.NewDecoder(strings.NewReader(resp.String()))
dec.Decode(&data)
jq := jsonq.NewQuery(data)

results, err := jq.Array("results")

if err != nil {
    log.Fatalln("Unable to get results: ", err)
}
if len(results) == 0 {
    return nil
}
return results // this is returning an interface{}

Answer 1

I should have checked the type I was dealing with. I found out by:

fmt.Println(reflect.TypeOf(results))

which returned: []interface {}

I was then able to iterate over it by using:

for _, event:= range results {
        v, err := json.MarshalIndent(event, "", "  ")
        if err != nil {
            fmt.Println("error:", err)
        }
        fmt.Println(string(v))
    }
