接口说明

网页翻译API接口提供写逸的翻译服务，可对网页html标签自动识别，翻译所需内容，目前支持中英、中日、中韩双向共6个语言方向。

网页翻译API HTTPS地址：

https://openapi.youdao.com/translate_html

协议须知

调用方在集成网页翻译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. 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。
