查詢單詞信息

在有道雲的Demo中，已經很完整的給出了相應的代碼~

但是針對是的英-漢等翻譯，如何只查詢單個單詞的詳細信息，包含單詞的翻譯/音標/釋義等？例如下圖示例信息：

 

 

下面修改后封裝的查詢單詞詳細信息服務（僅供參考）： 

 1     /// <summary>
 2     /// 有道詞典API
 3     /// </summary>
 4     internal class YouDaoApiService
 5     {
 6         const string AppKey = "131b76a4ee1ecd13";//AppKey和AppSecret是本人@Winter申請的賬號，僅供測試使用
 7         const string LangEn = "en";
 8         const string AppSecret = "KX9hLrgSMhfKkvIqS6nhwtwMcRymJqEA";
 9 
10         public static async Task<YouDaoTranslationResponse> GetTranslatioAsync(string queryText, string from = LangEn, string to = LangEn)
11         {
12             var requestUrl = GetRequestUrl(queryText, from, to);
13 
14             WebRequest translationWebRequest = WebRequest.Create(requestUrl);
15 
16             var response = await translationWebRequest.GetResponseAsync();
17 
18             using (Stream stream = response.GetResponseStream())
19             {
20                 using (StreamReader reader = new StreamReader(stream ?? throw new InvalidOperationException("有道Api查詢出錯！"), Encoding.GetEncoding("utf-8")))
21                 {
22                     string result = reader.ReadToEnd();
23                     var youDaoTranslationResponse = JsonConvert.DeserializeObject<YouDaoTranslationResponse>(result);
24 
25                     return youDaoTranslationResponse;
26                 }
27             }
28         }
29 
30         private static string GetRequestUrl(string queryText, string from, string to)
31         {
32             string salt = DateTime.Now.Millisecond.ToString();
33 
34             MD5 md5 = new MD5CryptoServiceProvider();
35             string md5Str = AppKey + queryText + salt + AppSecret;
36             byte[] output = md5.ComputeHash(Encoding.UTF8.GetBytes(md5Str));
37             string sign = BitConverter.ToString(output).Replace("-", "");
38 
39             var requestUrl = string.Format(
40                 "http://openapi.youdao.com/api?appKey={0}&q={1}&from={2}&to={3}&sign={4}&salt={5}",
41                 AppKey,
42                 HttpUtility.UrlDecode(queryText, System.Text.Encoding.GetEncoding("UTF-8")),
43                 from, to, sign, salt);
44 
45             return requestUrl;
46         }
47     }

 注：值得一提的是，查詢單詞信息，en->en路徑有道提供的數據不完整，會返回301錯誤碼。聯系有道開發后，提供的方案是auto->zhs。

序列化解析的數據類：

[DataContract]

    public class YouDaoTranslationResponse

    {

        [DataMember(Name = "errorCode")]

        public string ErrorCode { get; set; }

 

        [DataMember(Name = "query")]

        public string QueryText { get; set; }

 

        [DataMember(Name = "speakUrl")]

        public string InputSpeakUrl { get; set; }

 

        [DataMember(Name = "tSpeakUrl")]

        public string TranslationSpeakUrl { get; set; }

 

        /// <summary>

        /// 首選翻譯

        /// </summary>

        [DataMember(Name = "translation")]

        public List<string> FirstTranslation { get; set; }

 

        /// <summary>

        /// </summary>

        [DataMember(Name = "basic")]

        public TranslationBasicData BasicTranslation { get; set; }

 

        ///// <summary>
