文檔翻譯 API 簡(jiǎn)介

說(shuō)明

Hi，您好，歡迎使用有道智云文檔翻譯API接口服務(wù)。

本文檔主要針對(duì)需要集成HTTP API的技術(shù)開(kāi)發(fā)工程師，詳細(xì)描述文檔翻譯能力相關(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(guò)以下方式聯(lián)系我們：

溫馨提示：

• 本文檔主要針對(duì)開(kāi)發(fā)人員，接入測(cè)試前需要獲取應(yīng)用ID和應(yīng)用密鑰；如果您還沒(méi)有，請(qǐng)按照新手指南 獲取。
• 平臺(tái)向每個(gè)賬戶贈(zèng)送50元的體驗(yàn)金，供用戶集成前測(cè)試所用，具體資費(fèi)規(guī)則詳見(jiàn) 文檔翻譯服務(wù)報(bào)價(jià) 。

接口說(shuō)明

文檔翻譯API接口提供有道的文檔翻譯服務(wù)。您只需要通過(guò)調(diào)用文檔翻譯API，傳入文檔的Base64編碼，指定源語(yǔ)言與目標(biāo)語(yǔ)言，通過(guò)POST請(qǐng)求方式，就可以將文檔中的文字內(nèi)容進(jìn)行翻譯。

文檔翻譯 API HTTPS地址：

• 文檔上傳接口

https://openapi.youdao.com/file_trans/upload

• 進(jìn)度查詢接口

https://openapi.youdao.com/file_trans/query

• 文檔下載接口

https://openapi.youdao.com/file_trans/download

協(xié)議須知

調(diào)用方在集成文本翻譯API時(shí)，請(qǐng)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(lái)訪問(wèn)服務(wù)。

• 文檔上傳接口

• 進(jìn)度查詢接口

• 文檔下載接口

簽名生成方法如下：

sha256(應(yīng)用ID + input + salt + curtime + 應(yīng)用密鑰)

其中，input的計(jì)算方式為：

• 文檔上傳接口

input = Base64（q）字符串（當(dāng)Base64（q）長(zhǎng)度小于等于20）
或
input = Base64（q）前10個(gè)字符前10個(gè)字符 + Base64（q）長(zhǎng)度 + Base64（q）后十個(gè)字符（當(dāng)Base64（q）長(zhǎng)度大于20）

• 其它接口

input = flownumber字符串（當(dāng)flownumber長(zhǎng)度小于等于20）。
或
input = flownumber前10個(gè)字符前10個(gè)字符 + flownumber長(zhǎng)度 + flownumber后十個(gè)字符（當(dāng)flownumber長(zhǎng)度大于20）

不同語(yǔ)言獲取時(shí)間戳，請(qǐng)參看 此鏈接

如果對(duì)簽名有疑問(wèn)，可以參看文檔末尾各語(yǔ)言demo。

輸出結(jié)果

返回的結(jié)果是json格式，具體說(shuō)明如下：

• 文檔上傳

• 進(jìn)度查詢接口

• 文檔下載接口
  若Content-Type為application/json，表示下載失敗，返回值為json，否則返回值為文件流。

示例

• 文檔上傳接口

返回結(jié)果：

{
    "errorCode": "0",   //錯(cuò)誤碼
    "flownumber": "C9193F8204484E51B7DDA604137AEE3D"   //文檔流水號(hào)
}

• 進(jìn)度查詢接口

返回結(jié)果：

{
    "errorCode": "0",   //錯(cuò)誤碼
    "status": 1,   //狀態(tài)碼
    "statusString": "上傳中'   //狀態(tài)描述
}

• 文檔下載接口

失敗時(shí)返回結(jié)果：

{
    "errorCode": "0"   //錯(cuò)誤碼
}

支持的語(yǔ)言表

下表為各語(yǔ)言對(duì)應(yīng)代碼：
