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
     
       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
      
       (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。
