问题描述
我是 C# 新手，Android 是我的过去。如果我没有正确解释或理解，很抱歉。
试图弄清楚如何在视图中显示多个 JSON 响应。这是我使用 shtml 的类：
public class Artist@R_392_4045@ion : IEnumerable
{
[display(Name = "Song Title:")]
public string Name { get; set; }
[display(Name = "Album Title:")]
public string Album { get; set; }
[DataType(DataType.Url)]
public string Image { get; set; }
}
shtml：
<div class="form-group col-md-offset-3 col-md-5">
<h2>Forecast for the selected city</h2>
<label asp-for="Name"></label>
<span class="badge">@Model.Name</span>
<br />
<label asp-for="Album"></label>
<span class="badge">@Model.Album</span>
<br />
<label asp-for="Image"></label>
<div class="display-field">
<img src="@Url.Content(Model.Image)/>"
<br />
</div>
这是我的控制器，我在其中硬编码了要显示的第一个位置以确保其正常工作：
public IActionResult Artist@R_392_4045@ion(string artistName)
{
ArtistInfoResponse artistResponse = _musicRepository.GetArtistResponse(artistName);
Artist@R_392_4045@ion viewmodel = new Artist@R_392_4045@ion();
if (artistResponse != null)
{
viewmodel.Name = artistResponse.Data[1].Title;
viewmodel.Album = artistResponse.Data[1].Album.Title;
viewmodel.Image = artistResponse.Data[1].Album.Cover;
}
return View(viewmodel);
}
现在我想在我的整个回复中重复这个观点。我已经阅读了 IEnumerable，但如果这是我需要的，我无法理解如何申请。
这里是我使用 RestSharp 获取 JSON 响应的地方：
ArtistInfoResponse IMusicRepository.GetArtistResponse(string artistName)
{
artistName = (char)34 + artistName + (char)34; //ensure the string is wa
RestClient client = new RestClient($"https://api.deezer.com/search?q=artist:{artistName}");
RestRequest request = new RestRequest(Method.GET);
IRestResponse response = client.Execute(request);
if (response.IsSuccessful)
{
// Deserialize the string content into JToken object
// var content = JsonConvert.DeserializeObject<JToken>(response.Content);
var content = JsonConvert.DeserializeObject<IEnumerable<ArtistInfoResponse>>(response.Content);
// Deserialize the JToken object into our ArtistInfoResponse Class
return content.ToObject<ArtistInfoResponse>(); // this line doesn't work Now
}
return null;
}
}
编辑添加类****************************
public class ArtistInfoResponse : IEnumerable
{
public SongInfo[] Data { get; set; }
public int Total { get; set; }
public string Next { get; set; }
public IEnumerator GetEnumerator()
{
throw new NotImplementedException();
}
}
public class SongInfo
{
public int Id { get; set; }
public bool Readable { get; set; }
public string Title { get; set; }
public string Title_short { get; set; }
public string Title_version { get; set; }
public string Link { get; set; }
public int Duration { get; set; }
public int Rank { get; set; }
public bool Explicit_lyrics { get; set; }
public int Explicit_content_lyrics { get; set; }
public int Explicit_content_cover { get; set; }
public string Preview { get; set; }
public string Md5_image { get; set; }
public Artist Artist { get; set; }
public Album Album { get; set; }
public string Type { get; set; }
}
public class Artist
{
public int Id { get; set; }
public string Name { get; set; }
public string Link { get; set; }
public string Picture { get; set; }
public string Picture_small { get; set; }
public string Picture_medium { get; set; }
public string Picture_big { get; set; }
public string Picture_xl { get; set; }
public string Tracklist { get; set; }
public string Type { get; set; }
}
public class Album
{
public int Id { get; set; }
public string Title { get; set; }
public string Cover { get; set; }
public string Cover_small { get; set; }
public string Cover_medium { get; set; }
public string Cover_big { get; set; }
public string Cover_xl { get; set; }
public string Md5_image { get; set; }
public string Tracklist { get; set; }
public string Type { get; set; }
}
}
解决方法
你必须遍历你的数据，因为它是一个列表。
@foreach (var item in Model)
{
<div>@item.Name</div>
<div>@item.Album</div>
}
我最终摆脱了类视图来填充 shtml，因为我想我不完全了解这个基础结构。我还删除了序列化对象本身的 IEnumerable 是 IEnumerable（我认为）。我现在有这样的 shtml：
@model MyMusicApp.Models.ArtistInfoResponse
@{ ViewData["Title"] = "艺术家信息"; }
<div class="container">
<div class="form-group col-md-offset-3 col-md-5">
<h2>Song Titles and Albums for @Model.Data[1].Artist.Name</h2>
@foreach (var item in Model.Data)
{
<span class="badge">@item.Title</span>
<br />
<span class="badge">@item.Album.Title</span>
<br />
<img src="@Url.Content(item.Album.Cover)" />
<hr />
}
</div>
</div>
<div class="container">
<div class="form-group col-md-offset-3 col-md-5">
<form method="get">
<button asp-controller="Home" asp-action="SearchArtist" class="btn btn-success">Return</button>
</form>
并填充它，将其从控制器传递到视图：
public IActionResult ArtistInformation(string artistName)
{
ArtistInfoResponse artistResponse = _musicRepository.GetArtistResponse(artistName);
return View(artistResponse);
}
我的客户在一个单独的类中，其中包含 GetArtistResponse：
ArtistInfoResponse IMusicRepository.GetArtistResponse(string artistName)
{
artistName = (char)34 + artistName + (char)34;
var client = new RestClient($"https://api.deezer.com/search?q=artist:{artistName}");
var request = new RestRequest(Method.GET);
IRestResponse response = client.Execute(request);
if (response.IsSuccessful)
{
// Deserialize the string content into JToken object
var content = JsonConvert.DeserializeObject<JToken>(response.Content);
// Deserialize the JToken object into our ArtistInfoResponse Class
return content.ToObject<ArtistInfoResponse>();
}
return null;
}
}
}
