查询单词信息

在有道云的Demo中，已经很完整的给出了相应的代码~

但是针对是的英-汉等翻译，如何只查询单个单词的详细信息，包含单词的翻译/音标/释义等？例如下图示例信息：

下面修改后封装的查询单词详细信息服务（仅供参考）：

 4     internal class YouDaoApiService
 5     {
 6         const string AppKey = "131b76a4ee1ecd13";//AppKey和AppSecret是本人@Winter申请的账号，仅供测试使用
 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查询出错！"), 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，查询单词信息，en->en路径有道提供的数据不完整，会返回301错误码。联系有道开发后，提供的方案是auto->zhs。

序列化解析的数据类：

[DataMember(Name = "errorCode")]

public string ErrorCode { get; set; }

[DataMember(Name = "query")]

public string QueryText { get; set; }
