C#调用谷歌翻译API
原资料为网上找到的原稿为:http://www.cnblogs.com/marso/p/google_translate_api.html(此处只做个人笔记参考)
主要分两块:通过WebRequest的方式请求内容;获取Get方式的请求参数(难点在于tk的获取)。
以下是TK的JS代码,把以下代码保存存到程序目录下
gettk.js
var b = function (a, b) { for (var d = 0; d < b.length - 2; d += 3) { var c = b.charAt(d + 2), c = "a" <= c ? c.charCodeAt(0) - 87 : Number(c), c = "+" == b.charAt(d + 1) ? a >>> c : a << c; a = "+" == b.charAt(d) ? a + c & 4294967295 : a ^ c } return a } var tk = function (a,TKK) { for (var e = TKK.split("."), h = Number(e[0]) || 0, g = [], d = 0, f = 0; f < a.length; f++) { var c = a.charCodeAt(f); 128 > c ? g[d++] = c : (2048 > c ? g[d++] = c >> 6 | 192 : (55296 == (c & 64512) && f + 1 < a.length && 56320 == (a.charCodeAt(f + 1) & 64512) ? (c = 65536 + ((c & 1023) << 10) + (a.charCodeAt(++f) & 1023), g[d++] = c >> 18 | 240, g[d++] = c >> 12 & 63 | 128) : g[d++] = c >> 12 | 224, g[d++] = c >> 6 & 63 | 128), g[d++] = c & 63 | 128) } a = h; for (d = 0; d < g.length; d++) a += g[d], a = b(a, "+-a^+6"); a = b(a, "+-3^+b+-f"); a ^= Number(e[1]) || 0; 0 > a && (a = (a & 2147483647) + 2147483648); a %= 1E6; return a.toString() + "." + (a ^ h) }
然后在C#程序只引入Json.net(这个我用的版本为net4.5),然后再引入system.wed.dll(文件目录为:C:\WINDOWS\Microsoft.NET\Framework\找到相应版本)
以下为测试程序
using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Net; using System.Text; using System.Text.RegularExpressions; using System.Threading.Tasks; using System.Web; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { google test = new google(); Console.WriteLine(test.GoogleTranslate("RCC_APB2Periph: specifies the APB2 peripheral to gates its clock.This parameter can be any combination of the following values", "auto", "zh-CN")); Console.ReadKey(); } } class google { /// /// 谷歌翻译 /// /// 待翻译文本 /// 自动检测:auto /// 中文:zh-CN,英文:en /// 翻译后文本 public string GoogleTranslate(string text, string fromLanguage, string toLanguage) { CookieContainer cc = new CookieContainer(); string GoogleTransBaseUrl = "https://translate.google.cn/"; var BaseResultHtml = GetResultHtml(GoogleTransBaseUrl, cc, ""); Regex re = new Regex(@"(?<=TKK=)(.*?)(?=\);)"); var TKKStr = re.Match(BaseResultHtml).ToString() + ")";//在返回的HTML中正则匹配TKK的JS代码 var TKK = ExecuteScript(TKKStr, TKKStr);//执行TKK代码,得到TKK值 var GetTkkJS = File.ReadAllText("./gettk.js"); var tk = ExecuteScript("tk(\"" + text + "\",\"" + TKK + "\")", GetTkkJS); string googleTransUrl = "https://translate.google.cn/translate_a/single?client=t&sl=" + fromLanguage + "&tl=" + toLanguage + "&hl=en&dt=at&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t&ie=UTF-8&oe=UTF-8&otf=1&ssel=0&tsel=0&kc=1&tk=" + tk + "&q=" + HttpUtility.UrlEncode(text); var ResultHtml = GetResultHtml(googleTransUrl, cc, "https://translate.google.cn/"); dynamic TempResult = Newtonsoft .Json.JsonConvert.DeserializeObject(ResultHtml); string ResultText = Convert.ToString(TempResult[0][0][0]); return ResultText; } public string GetResultHtml(string url, CookieContainer cookie, string refer) { var html = ""; var webRequest = WebRequest.Create(url) as HttpWebRequest; webRequest.Method = "GET"; webRequest.CookieContainer = cookie; webRequest.Referer = refer; webRequest.Timeout = 20000; webRequest.Headers.Add("X-Requested-With:XMLHttpRequest"); webRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8"; webRequest.UserAgent = " Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0)"; using (var webResponse = (HttpWebResponse)webRequest.GetResponse()) { using (var reader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8)) { html = reader.ReadToEnd(); reader.Close(); webResponse.Close(); } } return html; } /// /// 执行JS /// /// 参数体 /// JavaScript代码的字符串 /// private string ExecuteScript(string sExpression, string sCode) { MSScriptControl.ScriptControl scriptControl = new MSScriptControl.ScriptControl(); scriptControl.UseSafeSubset = true; scriptControl.Language = "JScript"; scriptControl.AddCode(sCode); try { string str = scriptControl.Eval(sExpression).ToString(); return str; } catch (Exception ex) { string str = ex.Message; } return null; } } }
