Hey guys,
The code where i call the marshal
I have been trying to decode a json object into a struct with nested structs. When the struct is 1 level deep it does not create problems, but if i have a struct with an attribute that is a struct i get the error present in the title. Here is part of the code :
Json :
Code :
{ "seasonId": 8, "queueId": 420, "gameId": 3239663966, "participantIdentities": [ { "player": { "currentPlatformId": "EUW1", "summonerName": "MineManuDeYutu", "matchHistoryUri": "/v1/stats/player_history/EUW1/219194561", "platformId": "EUW1", "currentAccountId": 219194561, "profileIcon": 1666, "summonerId": 68726031, "accountId": 219194561 }, "participantId": 1 }, { "player": { "currentPlatformId": "EUW1", "summonerName": "Just Deadly", "matchHistoryUri": "/v1/stats/player_history/EUW1/205050256", "platformId": "EUW1", "currentAccountId": 205050256, "profileIcon": 1666, "summonerId": 47317494, "accountId": 205050256 }, "participantId": 2 }, { "player": { "currentPlatformId": "EUW1", "summonerName": "CougarHunting", "matchHistoryUri": "/v1/stats/player_history/EUW1/36397748", "platformId": "EUW1", "currentAccountId": 36397748, "profileIcon": 1666, "summonerId": 32741461, "accountId": 36397748 }, "participantId": 3 }, { "player": { "currentPlatformId": "EUW1", "summonerName": "Loca111", "matchHistoryUri": "/v1/stats/player_history/EUW1/231580371", "platformId": "EUW1", "currentAccountId": 231580371, "profileIcon": 1665, "summonerId": 96106805, "accountId": 231580371 }, "participantId": 4 }, { "player": { "currentPlatformId": "EUW1", "summonerName": "BoostedRiven420", "matchHistoryUri": "/v1/stats/player_history/EUW1/231287442", "platformId": "EUW1", "currentAccountId": 231287442, "profileIcon": 1665, "summonerId": 95496854, "accountId": 231287442 }, "participantId": 5 }, { "player": { "currentPlatformId": "EUW1", "summonerName": "Hroom", "matchHistoryUri": "/v1/stats/player_history/EUW1/217895755", "platformId": "EUW1", "currentAccountId": 217895755, "profileIcon": 1665, "summonerId": 66941009, "accountId": 217895755 }, "participantId": 6 }, { "player": { "currentPlatformId": "EUW1", "summonerName": "Nyss3", "matchHistoryUri": "/v1/stats/player_history/EUW1/22525212", "platformId": "EUW1", "currentAccountId": 22525212, "profileIcon": 1665, "summonerId": 19693763, "accountId": 22525212 }, "participantId": 7 }, { "player": { "currentPlatformId": "EUW1", "summonerName": "Number2333", "matchHistoryUri": "/v1/stats/player_history/EUW1/225600988", "platformId": "EUW1", "currentAccountId": 225600988, "profileIcon": 1665, "summonerId": 82017867, "accountId": 225600988 }, "participantId": 8 }, { "player": { "currentPlatformId": "EUW1", "summonerName": "Asianpowerbabe", "matchHistoryUri": "/v1/stats/player_history/EUW1/204195645", "platformId": "EUW1", "currentAccountId": 204195645, "profileIcon": 1665, "summonerId": 45862904, "accountId": 204195645 }, "participantId": 9 }, { "player": { "currentPlatformId": "EUW1", "summonerName": "DynastyBeast", "matchHistoryUri": "/v1/stats/player_history/EUW1/39635851", "platformId": "EUW1", "currentAccountId": 39635851, "profileIcon": 1666, "summonerId": 36712797, "accountId": 39635851 }, "participantId": 10 } ], "gameVersion": "7.12.190.9002", "platformId": "EUW1", "gameMode": "CLASSIC", "mapId": 11, "gameType": "MATCHED_GAME",
Code :
type DetailedMatch struct { SeasonId int
QueueId int
GameId int
ParticipantIdentities []ParticipantIty
GameVersion string
PlatformId string
GameMode string
MapId int
GameType string
Teams []Team
Participants json.RawMessage
GameDuration int
GameCreation int
}
type ParticipantIty struct {
ParticipantId int
Player []Player
}
type Player struct {
CurrentPlatformId string `json:"currentPlatformId"`
SummonerName string `json:"summonerName"`
MatchHistoryUri string `json:"matchHistoryUri"`
PlatformId string `json:"platformId"`
CurrentAccountId int `json:"currentAccountId"`
ProfileIcon int `json:"profileIcon"`
SummonerId int `json:"summonerId"`
AccountId int `json:"accountId"`
}
The code where i call the marshal
func GetMatchById(matchId string, server string) (*DetailedMatch, error) { var Response, err = http.Get(fmt.Sprintf(ENDPOINT_MATCH_BY_GAME_ID, server, matchId, string(KEY))) var Details = DetailedMatch{}
if err != nil { fmt.Println(123) return &Details, err } else { var ByteResponse, ByteError = ioutil.ReadAll(Response.Body) if ByteError != nil { fmt.Println(124) return &Details, ByteError } else { var UnmarshalError = json.Unmarshal(ByteResponse, &Details) if UnmarshalError != nil { fmt.Println(UnmarshalError) return &Details, UnmarshalError } else { return &Details, nil } } } }
