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:

C# 有道API翻译 查询单词详细信息-LMLPHP

下面修改后封装的查询单词详细信息服务(仅供参考):

     /// <summary>
/// 有道词典API
/// </summary>
internal class YouDaoApiService
{
const string AppKey = "131b76a4ee1ecd13";//AppKey和AppSecret是本人@Winter申请的账号,仅供测试使用
const string LangEn = "en";
const string AppSecret = "KX9hLrgSMhfKkvIqS6nhwtwMcRymJqEA"; public static async Task<YouDaoTranslationResponse> GetTranslatioAsync(string queryText, string from = LangEn, string to = LangEn)
{
var requestUrl = GetRequestUrl(queryText, from, to); WebRequest translationWebRequest = WebRequest.Create(requestUrl); var response = await translationWebRequest.GetResponseAsync(); using (Stream stream = response.GetResponseStream())
{
using (StreamReader reader = new StreamReader(stream ?? throw new InvalidOperationException("有道Api查询出错!"), Encoding.GetEncoding("utf-8")))
{
string result = reader.ReadToEnd();
var youDaoTranslationResponse = JsonConvert.DeserializeObject<YouDaoTranslationResponse>(result); return youDaoTranslationResponse;
}
}
} private static string GetRequestUrl(string queryText, string from, string to)
{
string salt = DateTime.Now.Millisecond.ToString(); MD5 md5 = new MD5CryptoServiceProvider();
string md5Str = AppKey + queryText + salt + AppSecret;
byte[] output = md5.ComputeHash(Encoding.UTF8.GetBytes(md5Str));
string sign = BitConverter.ToString(output).Replace("-", ""); var requestUrl = string.Format(
"http://openapi.youdao.com/api?appKey={0}&q={1}&from={2}&to={3}&sign={4}&salt={5}",
AppKey,
HttpUtility.UrlDecode(queryText, System.Text.Encoding.GetEncoding("UTF-8")),
from, to, sign, salt); return requestUrl;
}
}

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:

     [DataContract]

public string ErrorCode { get; set; } [DataMember(Name = "query")]
public string QueryText { get; set; } [DataMember(Name = "speakUrl")]
