可以看到，利用GET请求方式，带入某些参数，就会返回一个json数组，QueryString参数如下：
同样的，我们只需要传入这三个参数，就可以获得我们想要的翻译内容，公开方法，代码如下。
1 static string TranslateGoogleString(string translateContent, string fromLanguage = "zh-CN", string toLanguage = "en") 2 { 3 string transRetHtml = string.Empty; 4 5 string encodedStr = HttpUtility.UrlEncode(translateContent); //URL编码 6 string url = string.Format("http://translate.google.cn/translate_a/single?client=t&sl={0}&tl={1}&hl={0}&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t&dt=at&ie=UTF-8&oe=UTF-8&ssel=6&tsel=3&kc=0&tk=522626|172097&q={2}", fromLanguage, toLanguage, encodedStr); 7 8 try 9 { 10 var bytes = new WebClient().DownloadData(url); 11 transRetHtml = Encoding.UTF8.GetString(bytes); 12 13 var index = transRetHtml.IndexOf("]],"); 14 transRetHtml = transRetHtml.Substring(0, index + 1).Replace("[[", ""); 15 transRetHtml = transRetHtml = transRetHtml.Replace("[\"", ""); 16 transRetHtml = transRetHtml.Substring(0, transRetHtml.IndexOf("\"")); 17 18 } 19 catch (Exception ex) 20 { 21 } 22 23 return transRetHtml; 24 }
我们来试一试：
1 static void Main(string[] args) 2 { 3 string str = TranslateGoogleString("梦想"); 4 Console.WriteLine(str); 5 Console.ReadLine(); 6 }
