網(wǎng)頁翻譯 API 簡介

概念解釋

網(wǎng)頁翻譯：可對網(wǎng)頁html標(biāo)簽自動識別，翻譯所需內(nèi)容。

說明

Hi，您好，歡迎使用有道智云網(wǎng)頁翻譯API接口服務(wù)。

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)描述網(wǎng)頁翻譯能力相關(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：

商務(wù)郵箱： AIcloud_Business@corp.youdao.com

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。
• 平臺向每個賬戶贈送50元的體驗金，供用戶集成前測試所用，具體資費(fèi)規(guī)則詳見 網(wǎng)頁翻譯服務(wù)報價 。

接口說明

網(wǎng)頁翻譯API接口提供有道的翻譯服務(wù)，可對網(wǎng)頁html標(biāo)簽自動識別，翻譯所需內(nèi)容，支持多語種進(jìn)行翻譯，詳情參考支持的語種列表。

協(xié)議須知

調(diào)用方在集成網(wǎng)頁翻譯API時，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的計算方式為：input=q前10個字符 + q長度 + q后10個字符（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. 接口salt+curtime來防重放（即一個請求不可以被請求2次），所以salt最好為UUID。

不同語言獲取時間戳，請參看此鏈接

如果對簽名有疑問，可以參看各語言demo。

用戶術(shù)語表使用

登錄控制臺，選擇網(wǎng)頁翻譯服務(wù)，點(diǎn)擊右側(cè)的術(shù)語表，選擇新建，填寫表名稱和語言方向，添加需要的術(shù)語表獲取對應(yīng)詞表id即可。

輸出結(jié)果

注意：若列表語言出現(xiàn)不支持的問題，請參文檔下方或者考產(chǎn)品定價列表語種互譯的限制
