将字典序列化为JSON的奇怪结果

本文关键字:结果 JSON 字典 序列化 | 更新日期: 2023-09-27 18:11:49

我目前正在考虑将WCF用于REST服务。我遇到的一个问题是序列化作为字典的结果。我使用了这篇文章中建议的包装器类来序列化一个由字符串表示的日期组成的字典。"20.10.2011")和书。当我测试结果时,我看到如下:

{
    "DeparturesResult":
    {
        "_x0032_1.10.2011":true,
        "_x0032_4.10.2011":true,
        "_x0032_6.10.2011":true,
        "_x0032_8.10.2011":true,
        "_x0033_1.10.2011":true
    }
}

. .每个键的第一个字符被写成UTF-8代码。如果我在字符串前加上一个字母,我就不会遇到这个问题。(如d21.10.2011)

下面是我用来序列化字典的代码:公共类FlService: IFlService{#region IFlService Members

    public AjaxDictionary<string, bool> Departures(string from, string to, string portFrom, string portTo)
    {
        var startDate = DateTime.Today; // DateTime.ParseExact(from, "dd.MM.yyyy", null);
        var endDate = DateTime.ParseExact(to, "dd.MM.yyyy", null);
        var client = new Timetables();
        var result = client.GetJourneys(startDate, endDate.AddDays(1), portFrom, portTo);
        var js = result
            .GroupBy(x => x.DepartureTime.CarResToDateTime())
            .Select(x => x.Key)
            .OfType<DateTime>()
            .Select(x => x.Date)
            .Distinct()
            .ToDictionary(x => x.Date.ToString("dd.MM.yyy"), x => true);
        return new AjaxDictionary<string, bool>(js);
    }
    #endregion
    #region Nested type: AjaxDictionary
    [Serializable]
    public class AjaxDictionary<TKey, TValue> : ISerializable
    {
        private readonly Dictionary<TKey, TValue> _dictionary;
        public AjaxDictionary()
        {
            _dictionary = new Dictionary<TKey, TValue>();
        }
        public AjaxDictionary(Dictionary<TKey, TValue> dic)
        {
            _dictionary = dic;
        }
        public AjaxDictionary(SerializationInfo info, StreamingContext context)
        {
            _dictionary = new Dictionary<TKey, TValue>();
        }
        public TValue this[TKey key]
        {
            get { return _dictionary[key]; }
            set { _dictionary[key] = value; }
        }
        #region ISerializable Members
        public void GetObjectData(SerializationInfo info, StreamingContext context)
        {
            foreach (var key in _dictionary.Keys)
                info.AddValue(key is string ? key as string : key.ToString(), _dictionary[key]);
        }
        #endregion
        public void Add(TKey key, TValue value)
        {
            _dictionary.Add(key, value);
        }
    }
    #endregion
}

编辑:给接受的答案添加注释:这对于javascript是正确的,但对于JSON就不是这样了。序列化器似乎有点狂热,不仅序列化为JSON,而且还确保JSON是javascript。添加完整的JSON语法,见https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/JSON

JSON = null
    or true or false
    or JSONNumber
    or JSONString
    or JSONObject

PositiveNumber = DecimalNumber
              or DecimalNumber . Digits

             or OneToNine Digits
ExponentPart = e Exponent
            or E Exponent
Exponent = Digits
        or + Digits
        or - Digits

      or Digits Digit
Digit = 0 through 9

将字典序列化为JSON的奇怪结果

这是因为在JSON(或JavaScript)中键名(或JavaScript中的属性)不能以数字值开头,因此它将这些字符序列化后,以确保它们是正确的JSON格式
