利用bing圖片搜索接口開發圖片搜索應用程序

概述：通過bing的圖片搜索引擎，開發自己的圖片搜索應用程序。bing的圖片搜索接口是收費的，但是初次注冊使用，key可以免費試用30天

程序運行效果如下

一，代碼如下

static SearchResult BingImageSearch(string searchQuery)
        {
            // Construct the URI of the search request
            var uriQuery = uriBase + "?q=" + Uri.EscapeDataString(searchQuery);
            // Perform the Web request and get the response
            WebRequest request = HttpWebRequest.Create(uriQuery);
            request.Headers["Ocp-Apim-Subscription-Key"] = accessKey;
            HttpWebResponse response = (HttpWebResponse)request.GetResponseAsync().Result;
            string json = new StreamReader(response.GetResponseStream()).ReadToEnd();
            // Create result object for return
            var searchResult = new SearchResult()
            {
                jsonResult = json,
                relevantHeaders = new Dictionary<String, String>()
            };

            // Extract Bing HTTP headers
            foreach (String header in response.Headers)
            {
                if (header.StartsWith("BingAPIs-") || header.StartsWith("X-MSEdge-"))
                    searchResult.relevantHeaders[header] = response.Headers[header];
            }
            return searchResult;
        }

通過該方法返回一個json格式的搜索結果

二、點擊搜索的時候

private void Button_Click(object sender, RoutedEventArgs e)
        {
            searchInfo.List.Clear();
            string searchTerm = searchInfo.SearchTerm;
            SearchResult result = BingImageSearch(searchTerm);
            JObject jo = (JObject)JsonConvert.DeserializeObject(result.jsonResult);
            IJEnumerable<JToken> values = jo["value"]; ;
            foreach (JToken jk in values)
            {
                string imageUrl = jk["contentUrl"].ToString();
                string imageTitle = jk["name"].ToString();
                SearchItemResult sr = new SearchItemResult();
                sr.Url = imageUrl;
                sr.Title = imageTitle;
                searchInfo.List.Add(sr);
            }

把搜索結果添加到list里面。
        }
