golang json and slices of interface

Question

I am having trouble iterating over slices of interfaces that contain slices of interfaces.

This problem has arisen through attempting to work with an API call which retu

You can add a switch case which is checking the type of interface for slice of interfaces and then run the same function as recursive until whole json is parsed.

output := make(map[string]interface{})
err = json.Unmarshal(body, &output)

fmt.Println(err)
identify(output)

return err
}

func identify(output map[string]interface{}) {
    fmt.Printf("%T", output)
    for a, b := range output {
        switch bb := b.(type) {
        case string:
            fmt.Println("This is a string")
        case float64:
            fmt.Println("this is a float")
        case []interface{}:
        // Access the values in the JSON object and place them in an Item
        for _, itemValue := range jsonObj {
            fmt.Printf("%v is an interface\n", itemValue)
            identify(itemValue.(map[string]interface{}))
        }
        default:
            return
        }
    }
}

There can be deep nested json. We just needs to create options for each case until json is completely parsed.
