Я пытаюсь запросить объект json из базы данных через API.Но возвращенный результат был jsonArray.Поэтому я пытаюсь преобразовать объект jsonArray в объект json для печати пользователю.
Я пробовал два разных метода, но он выдает ошибку.
Метод 1:
public static async Task<JobModel> LoadJobIndex1(string specificValue)//Posting Type
{
string url = $"https://data.cityofnewyork.us/resource/kpav-sd4t.json?$limit=1&posting_type={ specificValue }";
using (HttpResponseMessage response = await ApiHelper.ApiHelper.ApiClient.GetAsync(url))
{
if (response.IsSuccessStatusCode)
{
var client = new WebClient();
var result = client.DownloadString("https://data.cityofnewyork.us/resource/kpav-sd4t.json?$limit=1&level=1");
JobResultModel results = JsonConvert.DeserializeObject<JobResultModel>(result);
}
else
{
throw new Exception(response.ReasonPhrase);
}
}
}
Метод 2:
public static async Task<JobModel> LoadJobIndex2(string specificValue)//Job Difficulty
{
string url = $"https://data.cityofnewyork.us/resource/kpav-sd4t.json?$limit=3&level={ specificValue }";
using (HttpResponseMessage response = await ApiHelper.ApiHelper.ApiClient.GetAsync(url))
{
if (response.IsSuccessStatusCode)
{
JobResultModel result = await response.Content.ReadAsAsync<JobResultModel>();
return result.Results;
}
else
{
throw new Exception(response.ReasonPhrase);
}
}
}
Я пытаюсь создать модель для хранения ответа.
public class JobResultModel
{
public List<JobModel> Results { get; set; }
}
public class JobModel
{
public string Business_title { get; set; }//Name of the job
public string Posting_type { get; set; }//Internal/External
public string Level { get; set; }//Diffculty of the job
public string Full_time_part_time_indicator { get; set; }
public string Salary_range_from { get; set; }
public string Salary_range_to { get; set; }
public string Job_description { get; set; }
public string Minimum_qual_requirements { get; set; }
public string Preferred_skills { get; set; }
public string To_apply { get; set; }
}
После этого я пытаюсь распечатать результат для пользователя.
var job = await GetJobDialog.LoadJobIndex1(specficValue);
await context.PostAsync($"Job Search Result : {Environment.NewLine}{JsonConvert.SerializeObject(job)}");
Вот пример результата
