批量翻譯 API 簡介

批量翻譯：支持一次傳入多個(gè)文本進(jìn)行批量翻譯，大幅減少http網(wǎng)絡(luò)應(yīng)答。適合多段文本批量翻譯的場景。

說明

Hi，您好，歡迎使用有道智云批量翻譯API接口服務(wù)。如果您想快速體驗(yàn)服務(wù)，建議您前往翻譯體驗(yàn)中心 或者在體驗(yàn)中心右下側(cè)找到小程序二維碼，掃描進(jìn)行體驗(yàn)。

本文檔主要針對需要集成HTTP API的技術(shù)開發(fā)工程師，詳細(xì)描述批量翻譯能力相關(guān)的技術(shù)內(nèi)容。

如果您有與我們商務(wù)合作的需求，可以通過以下方式聯(lián)系我們：

溫馨提示：

• 本文檔主要針對開發(fā)人員，接入測試前需要獲取 應(yīng)用ID 和 應(yīng)用密鑰 ；如果您還沒有，請按照新手指南 獲取。
• 平臺向每個(gè)賬戶贈送50元的體驗(yàn)金，供用戶集成前測試所用，具體資費(fèi)規(guī)則詳見 批量翻譯服務(wù)報(bào)價(jià) 。

接口說明

批量翻譯API接口提供有道的翻譯服務(wù)，包含了中英翻譯和小語種翻譯功能。您只需要通過調(diào)用批量翻譯API，傳入待翻譯的內(nèi)容，并指定要翻譯的源語言（支持源語言語種自動檢測）和目標(biāo)語言種類，就可以得到相應(yīng)的翻譯結(jié)果。

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

協(xié)議須知

調(diào)用方在集成批量翻譯API時(shí)，請遵循以下規(guī)則。

接口調(diào)用參數(shù)

調(diào)用API需要向接口發(fā)送以下字段來訪問服務(wù)。

簽名生成方法如下： signType=v3； sign=sha256(應(yīng)用ID+input+salt+curtime+應(yīng)用密鑰)； 其中，input的計(jì)算方式為：input=q前10個(gè)字符 + q長度 + q后10個(gè)字符（當(dāng)q長度大于20）或 input=q字符串（當(dāng)q長度小于等于20）；

注意：

1. voice 沒有男聲的，會輸出女聲。
2. 發(fā)音需要在控制臺創(chuàng)建tts應(yīng)用才能使用，否則點(diǎn)擊發(fā)音會報(bào)110錯誤。
3. 接口salt+curtime來防重放（即一個(gè)請求不可以被請求2次），所以salt最好為UUID。

不同語言獲取時(shí)間戳，請參看此鏈接

如果對簽名有疑問，可以參看各語言demo。

輸出結(jié)果

返回的結(jié)果是json格式，包含字段與FROM和TO的值有關(guān)，具體說明如下：

示例

{
    "errorCode": 返回結(jié)果代碼,
    "errorIndex": [
        1 //序號從0開始
    ],
    "translateResults": [
        {
            "query": 第一個(gè)q字段中的原文句子,
            "translation": 第一個(gè)i字段對應(yīng)的譯文句子,
            "type": 第一個(gè)q字段實(shí)際翻譯語言方向，
            "verifyResult": 第一個(gè)q字段語言方向核實(shí)結(jié)果
            
        }, 
        {
            "query": 第二個(gè)q字段中的原文句子,
            "translation": 第二個(gè)q字段對應(yīng)的譯文句子,
            "type": 第二個(gè)q字段實(shí)際翻譯語言方向，
            "verifyResult": 第一個(gè)q字段語言方向核實(shí)結(jié)果
        }
    ...
    ]
}

支持語言

下表為各語言對應(yīng)代碼：

其中auto可以識別中文、英文、日文、韓文、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，其他語種無法識別，為提高準(zhǔn)確率，請指定語種。
