New Features
- support encode object to map and vice versa. #309
The following example shows how that works:
person := Person{
Age: 18,
Sex: true,
}
worker1 := &Worker{
Person: person,
CurJob: JOB{Title: "cto", Company: "facebook"},
Jobs: []JOB{
{Title: "manager", Company: "google"},
{Title: "ceo", Company: "microsoft"},
},
}
e := NewEncoder()
err := e.Encode(worker1)
if err != nil {
t.Error(err)
t.FailNow()
}
data := e.Buffer()
// unRegisterPOJO before decode, so that to decode to map
unRegisterPOJO(person)
unRegisterPOJO(worker1)
unRegisterPOJO(&worker1.Jobs[0])
// strict mode
d := NewDecoder(data)
d.Strict = true // set to strict mode, then the decoding will return error for class not being registered.
res, err := d.Decode()
if err == nil {
t.Error("after unregister pojo, decoding should return error for strict mode")
t.FailNow()
}
// non-strict mode, decode to map for class not being registered.
d = NewDecoder(data)
res, err = d.Decode()
if err != nil {
t.Error(err)
t.FailNow()
}
worker2, ok := res.(map[string]interface{}) // the response is a map
if !ok {
t.Fatalf("res:%#v should be a map for non-strict mode", res)
}
// encode the map to object again, note the worker2 is a map.
e = NewEncoder()
err = e.Encode(worker2)
if err != nil {
t.Error(err)
t.FailNow()
}
data = e.Buffer()
// register pojo again, so that there are class definitions, which are used to encode map to object.
RegisterPOJO(person)
RegisterPOJO(worker1)
RegisterPOJO(&worker1.Jobs[0])
// decode the encoded map data to struct object.
d = NewDecoder(data)
res, err = d.Decode()
if err != nil {
t.Error(err)
t.FailNow()
}
worker3, ok := res.(*Worker) // worker3 is a Worker
if !ok {
t.Fatalf("res:%#v should be a worker type", res)
}
if !reflect.DeepEqual(worker1, worker3) {
t.Fatal("worker1 not equal to worker3!")
}
