微软认知服务网络搜索API - DeSerialization问题

Question

我想学习认知服务Web搜索API，所以我开始创建一个bot应用程序。我已经有一个帐户，子键和其他所需的信息，我还阅读了许多文章，并观看了2016年的建设视频，以及，我有困难，同时反序列化的结果。我无法找到我可以使用的代理类。我使用的url是https://api.cognitive.microsoft.com/bing/v5.0/search/，我为以前的api版本找到了一个代理类。有人能告诉我如何在VS 2015中获得这些服务的api请求/响应的代理类吗？

我的代码是这样的：

  string BingSearchUrl =  "https://api.cognitive.microsoft.com/bing/v5.0/search/";
   const string bingKey = "Key";

    public static  async Task<string> Search(string query)
    {
        var client = HttpClientFactory.Create();
        var queryString = BingSearchUrl + "?q=" + query + "&count=10";        
        // Request headers
        client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", bingKey);
        client.DefaultRequestHeaders.Add("Accept", "application/json");

        // Request parameters
        string r = await client.GetStringAsync(queryString);
        var jsonResult = JsonConvert.DeserializeObject<Bing.ExpandableSearchResult>(r);

        return jsonResult.Web.First().Title;

Answer 1

有了这个模型，我就能得到预期的结果。另一个答案中提出的模型在我的情况下是行不通的。

namespace BingSearchBot
{
    public class RootObject
    {
        public string _type { get; set; }
        public WebPages webPages { get; set; }
        public RelatedSearches relatedSearches { get; set; }
        public RankingResponse rankingResponse { get; set; }
    }
    public class WebPages
    {
        public string webSearchUrl { get; set; }
        public int totalEstimatedMatches { get; set; }
        public List<Value> value { get; set; }
    }
    public class Value
    {
        public string id { get; set; }
        public string name { get; set; }
        public string url { get; set; }
        public List<About> about { get; set; }
        public string displayUrl { get; set; }
        public string snippet { get; set; }
        public List<DeepLink> deepLinks { get; set; }
        public string dateLastCrawled { get; set; }
        public List<SearchTag> searchTags { get; set; }
    }
    public class About
    {
        public string name { get; set; }
    }

    public class DeepLink
    {
        public string name { get; set; }
        public string url { get; set; }
        public string snippet { get; set; }
    }

    public class SearchTag
    {
        public string name { get; set; }
        public string content { get; set; }
    }
    public class Value2
    {
        public string text { get; set; }
        public string displayText { get; set; }
        public string webSearchUrl { get; set; }
    }

    public class RelatedSearches
    {
        public string id { get; set; }
        public List<Value2> value { get; set; }
    }

    public class Value3
    {
        public string id { get; set; }
    }

    public class Item
    {
        public string answerType { get; set; }
        public int resultIndex { get; set; }
        public Value3 value { get; set; }
    }

    public class Mainline
    {
        public List<Item> items { get; set; }
    }

    public class RankingResponse
    {
        public Mainline mainline { get; set; }
    }
}

Answer 2

试试下面的代码

  public string BingSearchUrl = "https://api.cognitive.microsoft.com/bing/v5.0/search/";
        const string bingKey =[KEY];

        public async void Search()
        {
            var client = new HttpClient();
            var queryString = HttpUtility.ParseQueryString(string.Empty);

            // Request headers
            client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", bingKey);

            // Request parameters
            queryString["q"] = "microsoft";
            queryString["count"] = "10";
            queryString["offset"] = "0";
            queryString["mkt"] = "en-us";
            queryString["safeSearch"] = "Moderate";
            var uri = "https://api.cognitive.microsoft.com/bing/v5.0/news/search?" + queryString;

            var response = await client.GetStringAsync(uri);
            var jsonResult = JsonConvert.DeserializeObject<BingJson>(response);

            string title = jsonResult.value[0].name.ToString();

        }

使用jsonResult.value[0]，您可以循环查看结果。第一个结果是在[0]位置。

我创建了一个模型类，查看bing搜索响应json。看上去，

 public class BingJson
    {
        public string _type { get; set; }
        public Instrumentation instrumentation { get; set; }
        public string readLink { get; set; }
        public int totalEstimatedMatches { get; set; }
        public Value[] value { get; set; }
    }

    public class Instrumentation
    {
        public string pingUrlBase { get; set; }
        public string pageLoadPingUrl { get; set; }
    }

    public class Value
    {
        public string name { get; set; }
        public string url { get; set; }
        public string urlPingSuffix { get; set; }
        public Image image { get; set; }
        public string description { get; set; }
        public About[] about { get; set; }
        public Provider[] provider { get; set; }
        public DateTime datePublished { get; set; }
        public string category { get; set; }
    }

    public class Image
    {
        public Thumbnail thumbnail { get; set; }
    }

    public class Thumbnail
    {
        public string contentUrl { get; set; }
        public int width { get; set; }
        public int height { get; set; }
    }

    public class About
    {
        public string readLink { get; set; }
        public string name { get; set; }
    }

    public class Provider
    {
        public string _type { get; set; }
        public string name { get; set; }
    }
