从 Zendesk 获取门票并插入 SQL

Question

我正在尝试通过 Zendesk v2 API 从控制台应用程序获取 Zendesk 票证，然后插入到 sql 数据库，但出现错误。

Newtonsoft.Json.JsonSerializationException：无法将当前 JSON 对象（例如 {"name":"value"}）反序列化为类型 'System.Collections.Generic.List`1[ZenTrack.Class1+Ticket]'，因为该类型需要 JSON数组（例如 [1,2,3]）以正确反序列化。

错误 crystal 对于理解这一点的人来说是显而易见的...我不是那些人中的一员！我哪里做错了？

所以我的代码是这样的：

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using static ZenGet.Class1;

namespace ZenGet
{
    class Program
    {
        static void Main(string[] args)
        {
            HttpClient client = new HttpClient();
            client.BaseAddress = new Uri("https://myportal.zendesk.com/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Add("Authorization", "Basic xxxxxxxxxxxxxxxxxxxxxx");
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            string path = "api/v2/tickets.json?page=1";

            FileStream fs = new FileStream("c:\Test.txt", FileMode.Create);
            StreamWriter sw = new StreamWriter(fs);

            try
            {
                HttpResponseMessage response = client.GetAsync(path).Result;

                //Http Status code 200
                if (response.IsSuccessStatusCode)
                {
                    //Read response content result into string variable
                    string JSON = response.Content.ReadAsStringAsync().Result;

                    //Deserialize the string(JSON) object
                    var RootObjects = JsonConvert.DeserializeObject<List<Ticket>>(JSON);

                    foreach (var rootObject in RootObjects)
                    {
                        Console.WriteLine(rootObject.id + "-" + rootObject.subject + "-" + rootObject.description + "-" + rootObject.status);

                      // The SQL insert goes here.

                    }

                }
            }
            catch (Exception exception)
            {
                Console.SetOut(sw);
                Console.WriteLine($"Exception: {exception}");

            }
            sw.Close();


        }

    }
}

class 看起来像这样：

using Newtonsoft.Json;

using System.Collections.Generic;

我试过更改行： var RootObjects = JsonConvert.DeserializeObject<列表>(JSON); 到动态而不是 var 并动态 RootObjects = JsonConvert.DeserializeObject(JSON);

我在 class 中从

更改了

        public class Source
        {
            public From from { get; set; }
            public To to { get; set; }
            public object rel { get; set; }

至

        public class Source
        {
            [JsonProperty("from")]   <-- added this 
            public From from { get; set; }
            [JsonProperty("to")]     <-- added this 
            public To to { get; set; }
            [JsonProperty("rel")]    <-- added this 
            public object rel { get; set; }

您尝试将 json 对象反序列化为工单列表。但是您必须将其反序列化为包含票证列表的根对象：

变化：

 var RootObjects = JsonConvert.DeserializeObject<List<Ticket>>(JSON);

收件人：

var RootObjects = JsonConvert.DeserializeObject<Root>(JSON);
