I'm reverse engineering some JSON that seems to be using anonymous field names. For example:
{
"1": 123,
"2": 234,
"3": 345
}
BTW - it's not simply using "1" and "2" and "3" because they represent userids that are at a minimum int32's.
Is there some way such as using tags to properly Unmarshal the JSON?
I've tried:
package main
import (
"encoding/json"
"fmt"
)
type MyStruct struct {
string `json:",string"`
}
func main() {
jsonData := []byte("{\"1\":123,\"2\":234,\"3\":345}")
var decoded MyStruct
err := json.Unmarshal(jsonData, &decoded)
if err != nil {
panic(err)
}
fmt.Printf("decoded=%+v
", decoded)
}
Just decode the data into a map (map[string]int):
jsonData := []byte("{\"1\":123,\"2\":234,\"3\":345}")
var decoded map[string]int
err := json.Unmarshal(jsonData, &decoded)
if err != nil {
panic(err)
}
You'll then be able to iterate over and access the elements by the user ID key:
for userID, _ := range decoded {
fmt.Printf("User ID: %s
", userID)
}
