Question

我有以下课程：

public class Product
{
        [JsonProperty("image")]
        public string ImageURL { get; set; }
        [JsonProperty("superDepartment")]
        public string SuperDepartment { get; set; }
        [JsonProperty("tpnb")]
        public long TPNB { get; set; }
        [JsonProperty("ContentsMeasureType")]
        public string ContentsMeasureType { get; set; }
        [JsonProperty("name")]
        public string Name { get; set; }
        [JsonProperty("UnitOfSale")]
        public int UnitOfSale { get; set; }
        [JsonProperty("description")]
        public IEnumerator<string> LstDescription { get; set; }
        public string Description { get; set; }
        [JsonProperty("AverageSellingUnitWeight")]
        public decimal AverageSellingUnitWeight { get; set; }
        [JsonProperty("UnitQuantity")]
        public string UnitQuantity { get; set; }
        [JsonProperty("id")]
        public long ID { get; set; }
        [JsonProperty("ContentsQuantity")]
        public int ContentsQuantity { get; set; }
        [JsonProperty("department")]
        public string Department { get; set; }
        [JsonProperty("price")]
        public decimal Price { get; set; }
        [JsonProperty("unitprice")]
        public decimal UnitPrice { get; set; }
    }

我在productController上有方法：

    public async Task<ActionResult> MakeRequest(string q)// worked 
    {
        var client = new HttpClient();
        client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "56ac439a92694577a2779f3d0ee0cd85");

        var uri = string.Format("https://dev.tescolabs.com/grocery/products/?query={0}&offset={1}&limit={2}", q, 0, 10);

        var response = await client.GetAsync(uri);          
        string body = await response.Content.ReadAsStringAsync();
        Product myoutput = JsonConvert.DeserializeObject<Product>(body);
        }
        return View(body);
    }

我有下面的模型：

由于某种原因，当我调用方法MakeRequest时，它仅将信息显示为字符串，并显示错误消息，如下图所示，显示服务器错误，我们可以从api中看到信息，但它显示为字符串。 error message 来自api的信息应显示在下表中： table

如何在表格上显示数据？还是更好的如何将json数组转换为网络对象？

我知道我的方法下面的部分缺少一些东西

Product myoutput = JsonConvert.DeserializeObject<Product>(body);

Answer 1

您正在将json字符串而不是反序列化产品传递给View。我认为您的View期望使用的是Product类型的模型。

MakeRequest操作的return语句应为return View(myOutput);

Answer 2

我会简单地告诉你。

您的json模型

-uk --ghs -产品 ----结果

    "ghs" : {

          }
        ],
        "suggestions": []
      }
    }
  }
}

如果您查看上面的json结果，则需要一个更全面的模型。

为此，您可以在此处将json结果输入到模型中。 look here

或通过动态使结果对象保持其当前状态。

   string body = response.Content.ReadAsStringAsync().Result;

            dynamic content = JObject.Parse(body);

            var products = content.uk.ghs.products.results;

调用MakeRequest方法时，我的MVC无法显示正确的视图
