有道云C#Demo :
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）：
1 ///2 /// 有道词典API 3 /// 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 TaskGetTranslatioAsync(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。
序列化解析的数据类：
