如何使用必应翻译 API？

Question

我正在尝试使用必应翻译 API，但我很困惑。 似乎有很多可能性（旧的和新的），但我不明白我必须做什么。

有人可以帮帮我吗？

我想发送一个像http://api.microsofttranslator.com/V2/Ajax.svc/Translate?appId=<AppId>&to=de&text=World 这样的HTTP 请求并获得翻译。从哪里获取 AppId？

到目前为止我做了什么：

1. 已登录以免费使用 API (https://datamarket.azure.com/dataset/bing/microsofttranslator)
2. 创建了一个应用程序：https://datamarket.azure.com/developer/applications

现在我有了 Client_ID 和 Client_Secret，还有一个帐户密钥（在此处可见 https://datamarket.azure.com/account）

现在该怎么办？

非常感谢或任何帮助！

Answer 1

AppID 已弃用。您需要如何执行以下步骤：

1. 在https://datamarket.azure.com注册您的clientID、clientSecter
   
2. 那么您的代码必须获取访问令牌才能登录 BingTranslator API
   

在http://msdn.microsoft.com/en-us/library/dd576287.aspx上阅读更多详细信息

NB Microsoft Translator 已被 Bing Translate 取代，它似乎没有现成的 API。

Answer 2

点击http://api.microsofttranslator.com 上的链接。 API 采用 appid 参数中的访问令牌。请参阅文档中的“获取访问令牌”部分以了解如何获取该令牌。

Answer 3

请随意使用此说明（如果您使用的是 php）：

定义您的密钥

$apis['azure']['id'] = 123456789
$apis['azure']['key'] = 'abcde123456';

电话

echo get_translate_single('horse', 'en', 'es'); //this will print 'caballo'

或

echo get_translate(array('horse', 'house'), 'en', 'es'); //this will print array('caballo', 'casa')

就是这样，玩得开心记得关注terms of service。
