Unity 接入有道翻译接口API

        接入接口前首先需要申请应用ID和应用秘钥，登录有道智云AI开放平台，创建应用，获取应用ID和秘钥。

        定义接口响应类数据结构，接口实际返回内容和官方文档有点出入，大概是文档未更新吧。

以下是官方文档给出的说明：

以下是本人测试获取到的响应结构：

定义该数据结构：

[Serializable]
public class Response
{
    /// <summary>
    /// 单词校验后的结果 主要校验字母大小写、单词前含符号、中文简繁体
    /// </summary>
    public string[] returnPhrase;
    public string query;
    /// <summary>
    /// 错误返回码
    /// </summary>
    public string errorCode;
    /// <summary>
    /// 源语言和目标语言
    /// </summary>
    public string l;
    /// <summary>
    /// 翻译结果发音地址
    /// </summary>
    public string tSpeakUrl;
    /// <summary>
    /// 网络释义 不一定存在
    /// </summary>
    public Web[] web;
    public string requestId;
    /// <summary>
    /// 翻译结果
    /// </summary>
    public string[] translation;
    public URL dict;
    public URL webdict;
    /// <summary>
    /// 词义
    /// </summary>
    public Basic basic;
    public bool isWord;
    /// <summary>
    /// 源语言发音地址
    /// </summary>
    public string speakUrl;
}
[Serializable]
public class Web
{
    public string key;
    public string[] value;
}
[Serializable]
public class URL
{
    public string url;
}
[Serializable]
public class Basic
{
    public string phonetic;
    public string[] explains;
}

封装接口：

public class YoudaoTranslator
{
    //应用ID和应用秘钥 通过在平台创建应用获取
    private static readonly string appKey = "**********";
    private static readonly string appSecret = "********************";

    /// <summary>
    /// 将英文翻译为中文
    /// </summary>
    /// <param name="content">待翻译的文本</param>
    /// <param name="callback">回调函数</param>
    public static void EnglishToChinese(string content, Action<string> callback)
    {
        Translate(content, "en", "zh-CHS", callback);
    }
    /// <summary>
    /// 将中文翻译为英文
    /// </summary>
    /// <param name="content">待翻译的文本</param>
    /// <param name="callback">回调函数</param>
    public static void ChineseToEnglish(string content, Action<string> callback)
    {
        Translate(content, "zh-CHS", "en", callback);
    }
    /// <summary>
    /// 翻译
    /// 中文zh-CHS 英文en 日文ja 韩文ko 法文fr 德文de 俄文ru
    /// 其它语言查阅官方文档
    /// </summary>
    /// <param name="content">待翻译的文本</param>
    /// <param name="from">源语言</param>
    /// <param name="to">目标语言</param>
    /// <param name="callback">回调函数</param>
    public static void Translate(string content, string from, string to, Action<string> callback)
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://openapi.youdao.com/api");
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        //当前UTC时间戳（秒）
        string curtime = ((long)(DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds / 1000).ToString();
        //UUID 唯一通用识别码
        string salt = DateTime.Now.Millisecond.ToString();
        string input = content == null ? null : content.Length <= 20 ? content : (content.Substring(0, 10) + content.Length + content.Substring(content.Length - 10, 10));
        byte[] inputBytes = Encoding.UTF8.GetBytes(appKey + input + salt + curtime + appSecret);
        byte[] hashedBytes = new SHA256CryptoServiceProvider().ComputeHash(inputBytes);
        //签名 sha256(应用ID + input + salt + curtime + 应用秘钥)
        //其中input的计算方式为：input=content前10个字符 + content长度 + cotent后10个字符（当cotent长度大于20）或 input=content字符串（当content长度小于等于20）
        string sign = BitConverter.ToString(hashedBytes).Replace("-", "");
        //签名类型
        string signType = "v3";
        //参数列表
        string args = string.Format("from={0}&to={1}&signType={2}&curtime={3}&q={4}&appKey={5}&salt={6}&sign={7}",
            from, to, signType, curtime, content, appKey, salt, sign);
        byte[] data = Encoding.UTF8.GetBytes(args);
        request.ContentLength = data.Length;
        using (Stream reqStream = request.GetRequestStream())
        {
            reqStream.Write(data, 0, data.Length);
            reqStream.Close();
        }
        HttpWebResponse httpWebResponse = (HttpWebResponse)request.GetResponse();
        Stream stream = httpWebResponse.GetResponseStream();
        using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
        {
            string responseStr = reader.ReadToEnd();
            //Debug.Log(responseStr);
            //反序列化
            var response = JsonUtility.FromJson<Response>(responseStr);
            int errorCode = int.Parse(response.errorCode);
            switch (errorCode)
            {
                case 0: if (response.translation.Length > 0) callback.Invoke(response.translation[0]); break;
                case 102: Debug.LogError($"不支持的语言类型"); break;
                case 103: Debug.LogError($"翻译文本过长"); break;
                case 108: Debug.LogError($"应用ID无效 注册账号登录后台创建应用和实例并完成绑定 可获得应用ID和应用密钥等信息"); break;
                case 113: Debug.LogError($"待翻译文本不能为空"); break;
                //其它错误代码含义查阅官方文档
                default: Debug.LogError($"翻译失败 错误代码[{errorCode}]"); break;
            }
        }
    }
}

测试：

public class Foo : MonoBehaviour
{
    private void Start()
    {
        YoudaoTranslator.EnglishToChinese("Hello everyone.", s => Debug.Log(s));
        YoudaoTranslator.ChineseToEnglish("测试", s => Debug.Log(s));
    }
}
