1.开通百度翻译服务

在官网 百度翻译开放平台 开通通用翻译API

2.查看ID和Key

在管理控制台 -> 开发者信息 -> 申请信息栏中记下ID和密钥

3.使用官网Demo

将Demo中的appID和secretKey更改为自己的，运行后即可在控制台输出“苹果”的Unicode编码。

            // 原文
            string q = "apple";
            // 源语言
            string from = "en";
            // 目标语言
            string to = "zh";
            // 改成您的APP ID
            string appId = "2015063000000001";
            Random rd = new Random();
            string salt = rd.Next(100000).ToString();
            // 改成您的密钥
            string secretKey = "12345678";
            string sign = EncryptString(appId + q + salt + secretKey);
            string url = "http://api.fanyi.baidu/api/trans/vip/translate?";
            url += "q=" + HttpUtility.UrlEncode(q);

            url += "&appid=" + appId;
            url += "&salt=" + salt;
            url += "&sign=" + sign;
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Method = "GET";
            request.ContentType = "text/html;charset=UTF-8";
            request.UserAgent = null;
            request.Timeout = 6000;
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream myResponseStream = response.GetResponseStream();
            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));
            string retString = myStreamReader.ReadToEnd();
            myStreamReader.Close();
            myResponseStream.Close();
            Console.WriteLine(retString);
            Console.ReadLine();
        }
        // 计算MD5值
        public static string EncryptString(string str)
        {
            MD5 md5 = MD5.Create();
            // 将字符串转换成字节数组
            byte[] byteOld = Encoding.UTF8.GetBytes(str);
            // 调用加密方法
            byte[] byteNew = md5.ComputeHash(byteOld);
            // 将加密结果转换为字符串
            StringBuilder sb = new StringBuilder();
            foreach (byte b in byteNew)
            {
                // 将字节转换成16进制表示的字符串，
                sb.Append(b.ToString("x2"));
            }
            // 返回加密的字符串
            return sb.ToString();
        }
    }
}

开发

• Unicode码字符串转中文字符串：Regex.Unescape(unicode)
• 判断字符串相等：string.Compare(str1,str2) == 0
• 判断字符串中含有中文Regex.IsMatch(str, "[\u4e00-\u9fbb]")
• 字符串裁剪

int i = retString.IndexOf("dst");
int j = retString.IndexOf("}");
retString = retString.Substring(i + 6, j - i - 7);
