Question

我正在尝试反序列化 AchievementConfigurations：从此处列出 REST 响应 https://developers.google.com/games/services/publishing/api/achievementConfigurations/list。

问题是这一行只填充了顶级对象，而列表仍然是空的。不会抛出任何错误消息，这使得很难追踪正在发生的事情。我使用一个网站生成了 json 结构化 classes，然后我删除了不必要的重复项。

响应看起来像这样，我已经删除了 achievementConfiguration 资源，因为它真的很长但是可以在这里找到 https://developers.google.com/games/services/publishing/api/achievementConfigurations#resource

{
  "kind": "gamesConfiguration#achievementConfigurationListResponse",
  "nextPageToken": string,
  "items": [
    achievementConfigurations Resource
  ]
}

我创建了一系列 classes 以镜像从 AchievementConfigurationListResponse class

开始的数据

public class AchievementConfigurationListResponse
    {
        public string kind = "gamesConfiguration#achievementConfigurationListResponse";
        public string nextPageToken = "";

        List<AchievementConfigurationResource> items = new List<AchievementConfigurationResource>();
    }

接下来是 AchievementConfigurationResource，它是列表中的一个项目，它有几个嵌套对象

public class AchievementConfigurationResource
    {
        public static string[] types = new string[] { "STANDARD", "INCREMENTAL" };
        public static string[] states = new string[] { "REVEALED", "HIDDEN", "UNLOCKED" };

        public string kind = "gamesConfiguration#achievementConfiguration";
        public string token = "";
        public string id = "";
        public string achievementType = types[0];
        public string initialState = states[0];

        public int? stepsToUnlock;

        public AchievementConfigurationDetail draft = new AchievementDataResource();
        public AchievementConfigurationDetail published = new AchievementDataResource();
    }

那些嵌套对象属于此类 AchievementConfigurationDetail

public class AchievementConfigurationDetail
    {
        public string kind = "gamesConfiguration#achievementConfigurationDetail";
        public LocalizedStringBundle name = new LocalizedStringBundle();
        public LocalizedStringBundle description = new LocalizedStringBundle();
        public int pointValue = 5;
        public string iconUrl = "";
        public int sortRank = 1;
    }

其中包含几个LocalizedStringBundles

public class LocalizedStringBundle
    {
        public string kind = "gamesConfiguration#localizedStringBundle";
        public List<Translation> translations = new List<Translation>();

        public class Translation
        {
            public string kind = "gamesConfiguration#localizedString";
            public string locale = "en-US";
            public string value = "";
        }
    }

我在 json 上使用以下行调用它：

   AchievementConfigurationListResponse res = JsonConvert.DeserializeObject<AchievementConfigurationListResponse>(content);

这是响应的副本，删除了敏感数据，但密钥和结构都完好无损。这个文件只包含一条记录，因为整个文件大约有 5000 行长。

{
 "kind": "gamesConfiguration#achievementConfigurationListResponse",
 "items": [
  {
   "kind": "gamesConfiguration#achievementConfiguration",
   "token": "Unique Token",
   "id": "Unique ID",
   "achievementType": "STANDARD",
   "initialState": "REVEALED",
   "draft": {
    "kind": "gamesConfiguration#achievementConfigurationDetail",
    "name": {
     "kind": "gamesConfiguration#localizedStringBundle",
     "translations": [
      {
       "kind": "gamesConfiguration#localizedString",
       "locale": "en-US",
       "value": "Name"
      }
     ]
    },
    "description": {
     "kind": "gamesConfiguration#localizedStringBundle",
     "translations": [
      {
       "kind": "gamesConfiguration#localizedString",
       "locale": "en-US",
       "value": "Description"
      }
     ]
    },
    "pointValue": 5,
    "iconUrl": "Icon url",
    "sortRank": 1
   },
   "published": {
    "kind": "gamesConfiguration#achievementConfigurationDetail",
    "name": {
     "kind": "gamesConfiguration#localizedStringBundle",
     "translations": [
      {
       "kind": "gamesConfiguration#localizedString",
       "locale": "en-US",
       "value": "Name"
      }
     ]
    },
    "description": {
     "kind": "gamesConfiguration#localizedStringBundle",
     "translations": [
      {
       "kind": "gamesConfiguration#localizedString",
       "locale": "en-US",
       "value": "Description"
      }
     ]
    },
    "pointValue": 5,
    "iconUrl": "Icon url",
    "sortRank": 1
   }
  }
 ]
}

Answer 1

Json.NET 默认不序列化私有成员。因此，您需要使 AchievementConfigurationListResponse.items 成为 public:

public List<AchievementConfigurationResource> items = new List<AchievementConfigurationResource>();

或者，用 [JsonProperty] 标记它，启用私有成员的序列化：

[JsonProperty]
List<AchievementConfigurationResource> items = new List<AchievementConfigurationResource>();
