使用更改密钥反序列化JSON？

Question

我从服务中获得了以下JSON。

查看三个记录的样本：

{"[email protected]":[{"action":"open","timestamp":"2018-09-05 20:46:00","url":null,"ip":"66.102.6.98"}]}

{"[email protected]":[{"action":"open","timestamp":"2018-09-05 18:01:29","url":null,"ip":"66.102.8.129"}]}

{"[email protected]":[{"action":"open","timestamp":"2018-09-05 15:08:26","url":null,"ip":"66.102.6.109"}]}

第一个键总是在变化，那么将它转换为.NET对象的最佳方法是什么？

Answer 1

当它的密钥不同时，我不确定是否还有其他方法可以反序列化json。当密钥不同时，它被认为是另一种类型。您可以使用正则表达式剥离Json的常量部分并对其进行反序列化。

试试这是否有帮助

    public class CommonPart
{

    [JsonProperty("action")]
    public string action { get; set; }

    [JsonProperty("timestamp")]
    public string timestamp { get; set; }

    [JsonProperty("url")]
    public object url { get; set; }

    [JsonProperty("ip")]
    public string ip { get; set; }
}

public class EmailPart
{
    public string Email { get; set; }
    public IList<CommonPart> Model { get; set; }
}

然后使用方法获取如下所示的json

public EmailPart GetFromJson(string json)
    {
        var pattern = @"\[(.*?)\]";
        var regex = new Regex(pattern);
        var response = regex.Match(json);
        var test1GmailCom = response.Value;
        var responseModel = JsonConvert.DeserializeObject<List<CommonPart>>(test1GmailCom);

        var ex = new EmailPart();
        ex.Model = responseModel;

        var pattern2 = @"\'(.*?)\'";
        var regex2 = new Regex(pattern2);
        var email = regex2.Match(json).Value.Replace("'", string.Empty);

        ex.Email = email;

        return ex;

    }

我不认为这是最好的方式。最好是你可以更新Json，可能如下

{“Data”：{“[email protected]”：[{“action”：“open”，“timestamp”：“2018-09-05 20:46:00”，“url”：null，“ip” ：“66.102.6.98”}]}}

使用Cinchoo ETL（一个开源库），您可以将JSON加载到.NET对象，如下所示

.net对象定义

public class ActionMessage
{
    public string Action { get; set; }
    public DateTime Timestamp { get; set; }
    public string Url { get; set; }
    public string IP { get; set; }

}

JSON解析代码

string json = @"{
    ""[email protected]"": [
        {
            ""action"": ""open"",
            ""timestamp"": ""2018-09-05 20:46:00"",
            ""url"": ""http://www.google.com"",
            ""ip"": ""66.102.6.98""
        }
    ]
}";
using (var p = ChoJSONReader<ActionMessage>.LoadText(json)
    .WithJSONPath("$.*")
    )
{
    foreach (var rec in p)
    {
        Console.WriteLine("action: " + rec.Action);
        Console.WriteLine("timestamp: " + rec.Timestamp);
        Console.WriteLine("url: " + rec.Url);
        Console.WriteLine("ip: " + rec.IP);
    }
}

输出：

action: open
timestamp: 9/5/2018 8:46:00 PM
url: http://www.google.com
ip: 66.102.6.98
