BackendReturnObject(Return Value)
BackendReturnObject is a class that stores the value passed due to communication.
All functions requested to the server using BACKND SDK are returned as a BackendReturnObject class format.
| Value | Type | Description |
|---|---|---|
| statusCode | string | Status code passed from the server |
| errorCode | string | Code that signals error information |
| message | string | Details of success/failure passed from the server |
| returnValue | string | Data delivered in JSON format by the server when the request succeeds |
BackendReturnObject contains the response to the request in returnValue. This is in JSON format.
The JSON library uses LitJson, and you can check the api here.
Example
BackendReturnObject bro= Backend.BMember.AuthorizeFederation("AccessToken", FederationType.Google);
if(bro.IsSuccess() == false) {
// 서버에 에러가 리턴되었다면
Debug.Log(bro.ToString()); // 에러 정보 확인
return;
}
// Convert the server's response to a JSON object
var json = bro.GetFlattenJson();
