在.net core 2.0应用程序中反序列化后,我面临显示数据的问题。这就是我想要做的: 1-解压缩POST请求发送的文件(DONE) 2-建立资料模型(完成) 3-显示数据(不正确)
这是我的控制器:
ValuesController
using System;
using System.Collections.Generic;
using System.IO;
using System.IO.Compression;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
using HelloWorld.Models;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json;
// For more information on enabling Web API for empty projects, visit https://go.microsoft.com/fwlink/?LinkID=397860
namespace HelloWorld.Controllers
{
[Route("")]
public class ValuesController : Controller
{
// POST api/<controller>
[HttpGet]
[Route("/Values/Index")]
public IActionResult Index()
{
using (StreamReader r = new StreamReader("c:\\temp\\inplay-soccer.json"))
{
string json = r.ReadToEnd();
var objects = JsonConvert.DeserializeObject<Goalserve>(json);
return View(objects);
}
}
[HttpPost]
[Consumes("application/gzip")]
public async Task<IActionResult> PostAsync(IFormFile file)
{
WebClient Client = new WebClient();
Client.DownloadFile("http://inplay.goalserve.com/inplay-soccer.gz", "C:\\temp\\inplay-soccer.gz");
using (var inputFileStream = new FileStream("c:\\temp\\inplay-soccer.gz", FileMode.Open))
using (var gzipStream = new GZipStream(inputFileStream, CompressionMode.Decompress))
using (var outputFileStream = new FileStream("c:\\temp\\inplay-soccer.json", FileMode.Create))
{
await gzipStream.CopyToAsync(outputFileStream);
}
return Ok();
}
// PUT api/<controller>/5
[HttpPut("{id}")]
public void Put(int id, [FromBody]string value)
{
}
// DELETE api/<controller>/5
[HttpDelete("{id}")]
public void Delete(int id)
{
}
public class Value
{
public int Id { get; set; }
}
}
}
这是模型:

现在,如何在视图中显示数据?
我创建了一个名为“ Index.cshtml”的对应视图,并尝试使用ViewData,但我不知道该怎么做。这是我的查看代码
Index.cshtml
@page
@model HelloWorld.Models.Goalserve
@{
var objects = ViewData["Objects"];
}
<table>
<tr>
test
<td>@objects.ToString()</td>
</tr>
</table>
我知道查看代码“索引”是错误的。我应该怎么做才能显示反序列化的JSON提要(例如,每行中的每个信息)? (我需要在[Route(“ / Values / Index”)]中显示数据)
谢谢!

答案 0 :(得分:1)
请如下修改您的index.cshtml:
@model HelloWorld.Models.Goalserve
@{
var objects = Model; //ViewData["Objects"];
}
<table>
<tr>
test
<td>@objects.ToString()</td>
</tr>
请如下修改您的Goalserve和事件:
public partial class Goalserve
{
[JsonProperty("updated")]
public string Updated { get; set; }
[JsonProperty("updated_ts")]
public long UpdatedTs { get; set; }
[JsonProperty("events")]
//public Events Events { get; set; }
public Dictionary<string, Events> Events { get; set; }
public override string ToString()
{
return string.Format($"Updated={this.Updated} and UpdatedTs={this.UpdatedTs} and EventsCount={this.Events.Count}");
}
}
public partial class Events
{
//[JsonProperty("84586848")]
public The84586848 The84586848 { get; set; }
}
请修改您的Converter使其也包括ParseStringConverter:
internal static class Converter
{
public static readonly JsonSerializerSettings Settings = new JsonSerializerSettings
{
MetadataPropertyHandling = MetadataPropertyHandling.Ignore,
DateParseHandling = DateParseHandling.None,
Converters =
{
InfoEnumConverter.Singleton,
ParseStringConverter.Singleton,
new IsoDateTimeConverter { DateTimeStyles = DateTimeStyles.AssumeUniversal }
},
};
}
然后最后修改您的Controller Action以使用您的自定义设置,如下所示:
using (StreamReader r = new StreamReader("c:\\temp\\inplay-soccer.json"))
{
string json = r.ReadToEnd();
objects = JsonConvert.DeserializeObject<Goalserve>(json, Converter.Settings);
return View(objects);
}
上面的代码可以与您附加的示例json(文本文件)一起正常工作。您附加的json在事件集合下没有与键84586848匹配的对象。
侧面但相关的注意事项:如果要让NewtonSoft Json使用camelCase,则可以使用ContractResolver = new CamelCasePropertyNamesContractResolver()而不是在属性中添加[JsonProperty]批注。例如
internal static class Converter
{
public static readonly JsonSerializerSettings Settings = new JsonSerializerSettings
{
MetadataPropertyHandling = MetadataPropertyHandling.Ignore,
DateParseHandling = DateParseHandling.None,
ContractResolver = new CamelCasePropertyNamesContractResolver(),
Converters =
{
InfoEnumConverter.Singleton,
ParseStringConverter.Singleton,
new IsoDateTimeConverter { DateTimeStyles = DateTimeStyles.AssumeUniversal }
},
};
}
答案 1 :(得分:1)
为您提供json文件:
84586848
的模型属性,但您的json不包含此类属性。switch-case
中有InfoEnumConverter
条语句。它有三种可能,如果是另一种类型,它将引发异常。您需要设置默认的返回值而不是引发异常。(注意:您需要将[JsonConverter(typeof(InfoEnumConverter))]
添加到InfoEnum Info
属性中
)要适合您的json文件,您需要更改模型,如下所示:
public partial class Goalserve
{
[JsonProperty("updated")]
public string Updated { get; set; }
[JsonProperty("updated_ts")]
public long UpdatedTs { get; set; }
[JsonProperty("events")]
public Dictionary<string, The84586848> Events { get; set; }

return;
}
throw new Exception("Cannot marshal type InfoEnum");
}
public static readonly InfoEnumConverter Singleton = new InfoEnumConverter();
}
您的看法:
您没有将数据存储到ViewData["objects"]
,因此会出现错误,您可以进行如下修改:
1.Controller:
[HttpGet]
public IActionResult Index()
{
using (StreamReader r = new StreamReader("c:\\temp\\inplay-soccer.json"))
{
string json = r.ReadToEnd();
var objects = JsonConvert.DeserializeObject<Goalserve>(json);
return View(objects);
}
}
2。视图:
@model Goalserve
@{
var data = Model.Events.Keys.ToArray();
}
<table class="table">
<tr>
<td>@Model.Updated</td>
</tr>
<tr>
<td>@Model.UpdatedTs</td>
</tr>
<tr>
@for (var i = 0; i < data.Count(); i++)
{
<td>@Model.Events[data[i].ToString()].Core.Updated</td>
<td>@Model.Events[data[i].ToString()].Core.UpdatedTs</td>
<td>@Model.Events[data[i].ToString()].Info.Points</td>
<td>@Model.Events[data[i].ToString()].Info.Score</td>
//more property...
}
</tr>
</table>
注意:这种方式将数据显示到视图上并不容易,也很复杂。如果您不想更改模型,建议您也可以生成如下所示的json文件,由于您只有一个Event
(public Events Events { get; set; }
)在您的Goalserve
模型中:
