c#：使用百度翻译API

来源：互联网发布：线切割加工编程时编辑：程序博客网时间：2024/05/17 02:55

首先先在百度翻译开放平台上注册一下，然后得到两个关键值：App Id 和秘钥，有了这俩就可以直接写程序了。

写程序的时候参考一下开发手册

因为最后的返回结果是这样的

{"from":"en","to":"zh","trans_result":[{"src":"hello","dst":"\u4f60\u597d"}]}

先定义一个Translation.cs用了存放结果中的trans_result

public class Translation{    public string Src { get; set; }    public string Dst { get; set; }}

再定义一个TranslationResult存放上面结果的反序列化的结果

public class TranslationResult{    public string Error_code { get; set; }    public string Error_msg { get; set; }    public string From { get; set; }    public string To { get; set; }    public string Query { get; set; }    public Translation[] Trans_result { get; set; }}

之后是主体功能：拼接URL并访问然后得到结果
我现在使用的版本URL拼接格式是：
http://api.fanyi.baidu.com/api/trans/vip/translate?q=apple&from=en&to=zh&appid=2015063000000001&salt=1435660288&sign=f89f9594663708c1605f3d736d01d2d4
也就是百度翻译网址+要翻译的字符串+源语言+目的语言+appid+随机数字+md5校验值
这个有可能会变，反正这些帮助文档上写的都很详细

public static TranslationResult GetTranslationFromBaiduFanyi(String source, Language from = Language.Auto, Language to = Language.Auto){    String jsonResult = String.Empty;    String languageFrom = from.ToString().ToLower();    String languageTo = to.ToString().ToLower();    String appId = "123321123321";    String randomNum = System.DateTime.Now.Millisecond.ToString();    String md5Sign = GetMD5HashFromFile(appId + source + randomNum + "09090909090909");    Console.WriteLine(appId + source + randomNum + "Cxdi54XVRAnuMAbOjCMr");    String url = String.Format("http://api.fanyi.baidu.com/api/trans/vip/translate?q={0}&from={1}&to={2}&appid={3}&salt={4}&sign={5}",        HttpUtility.UrlEncode(source, Encoding.UTF8),        languageFrom,        languageTo,        appId,        randomNum,        md5Sign        );    Console.WriteLine(url);    WebClient wc = new WebClient();    try    {        jsonResult = wc.DownloadString(url);    }    catch (Exception e)    {        jsonResult = string.Empty;        Console.WriteLine(e.Message);    }    JavaScriptSerializer jss = new JavaScriptSerializer();    TranslationResult ret = jss.Deserialize<TranslationResult>(jsonResult);    return ret;}

上面用到的MD5在我之前的博客或者网上都能找到

还用到了一个枚举定义语言类型

public enum Language{    Auto = 0,    ZH = 1,    JP = 2,    EN = 3,    KOR = 4,    SPA = 5,    FRA = 6,    TH = 7,    ARA = 8,    RU = 9,    PT = 10,    YUE = 11,    WYW = 12,    DE = 13,    NL = 14,    IT = 15,    EL = 16}

调用时

private static void Main(String[] args){    TranslationResult result = TranslateUtil.GetTranslationFromBaiduFanyi("hello", TranslateUtil.Language.EN, TranslateUtil.Language.ZH);    for (int i = 0; i < result.Trans_result.Length; i++)    {        Console.WriteLine(result.Trans_result[i].Dst);    }}
