将 Json 数据传输到 C# 列表

using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json;
using pdrake.Models;

namespace pdrake.Controllers
{
    public class MovieApiController : Controller
    {
        private const string baseUrl = "https://api.themoviedb.org/3/discover/movie?api_key=my_key";
        public List<Movie> Movies { get; set; }
        public async Task<AcceptedResult> GetMovies()
        {
            using (var httpClient = new HttpClient())
            {
                httpClient.BaseAddress = new Uri(baseUrl);
                httpClient.DefaultRequestHeaders.Accept.Clear();
                httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            }
            Movies = JsonConvert.DeserializeObject<List<Movie>>(Json(baseUrl));
            return View(Movies);
        }
    }
}

我整天都在苦苦挣扎，试图弄清楚如何将 Json 从 baseUrl 转移到可以通过 foreach 循环循环的电影列表。

Answer 1

将您的 using 块更改为以下内容，

using (var httpClient = new HttpClient())
{
    var response = await httpClient.GetAsync(baseUrl);
    string data = await response.Content.ReadAsStringAsync();
    return View(JsonConvert.DeserializeObject<List<Movie>>(data));
}

这将调用 baseUrl 并从响应中接收文本/内容。获得数据后，您可以将其反序列化为 List<Movie> 对象并将其作为视图返回。
