接口说明

批量翻译API接口提供有道的翻译服务，包含了中英翻译和小语种翻译功能。您只需要通过调用批量翻译API，传入待翻译的内容，并指定要翻译的源语言（支持源语言语种自动检测）和目标语言种类，就可以得到相应的翻译结果。

批量翻译API HTTPS地址：

https://openapi.youdao.com/v2/api

协议须知

调用方在集成批量翻译API时，请遵循以下规则。

接口调用参数

调用API需要向接口发送以下字段来访问服务。

签名生成方法如下： signType=v3； sign=sha256(应用ID+input+salt+curtime+应用密钥)； 其中，input的计算方式为：input=q前10个字符 + q长度 + q后10个字符（当q长度大于20）或 input=q字符串（当q长度小于等于20）；

注意：

1. voice 没有男声的，会输出女声。
2. 发音需要在控制台创建tts应用才能使用，否则点击发音会报110错误。
3. 接口salt+curtime来防重放（即一个请求不可以被请求2次），所以salt最好为UUID。

不同语言获取时间戳，请参看此链接

如果对签名有疑问，可以参看各语言demo。

输出结果

返回的结果是json格式，包含字段与FROM和TO的值有关，具体说明如下：

| 字段名 | 类型 | 含义 | 备注 | |------ |----- |----- |---- | |errorCode |text |错误返回码 |一定存在| |errorIndex |JSONArray |错误结果的序号 |结果部分出错时存在。序号与输入的i字段顺序一一对应，序号从0开始。JSONArray中元素为int类型| |translateResults |JSONArray |翻译结果 |批量请求中存在正确结果时，一定存在。JSONArray中元素为JSONObject类型，JSONObject中一定包含query、translation和type字段（均为String类型），分别表示翻译原句、翻译结果和翻译所用的语言方向。|

示例

{
    "errorCode": 返回结果代码,
    "errorIndex": [
        1 //序号从0开始
    ],
    "translateResults": [
        {
            "query": 第一个q字段中的原文句子,
            "translation": 第一个i字段对应的译文句子,
            "type": 第一个q字段实际翻译语言方向，
            "verifyResult": 第一个q字段语言方向核实结果
            
        }, 
        {
            "query": 第二个q字段中的原文句子,
            "translation": 第二个q字段对应的译文句子,
            "type": 第二个q字段实际翻译语言方向，
            "verifyResult": 第一个q字段语言方向核实结果
        }
    ...
    ]
}

支持语言

下表为各语言对应代码：

其中auto可以识别中文、英文、日文、韩文、法文、西班牙文、葡萄牙文、俄文、越南文、德文、阿拉伯文、印尼文、意大利文，其他语种无法识别，为提高准确率，请指定语种。
