使用Microsoft Azure Text Translator API翻译示例文本的示例Java程序

Question

我正在尝试使用Microsoft Azure Text Translator API通过Java程序将示例文本从一种语言翻译成另一种语言。

请为我提供步骤，为Microsoft Azure Text Translator API创建appId，Secret密钥，并提供示例Java程序，将示例文本从一种语言转换为另一种语言。

提前致谢。

根据我的理解，我认为您希望在Java程序中使用Microsoft DataMarket中的Microsoft Translator - Text Translation，但似乎不知道如何开始使用它。

首先，您需要通过https://datamarket.azure.com/developer/applications/register注册申请才能获得client_id＆amp;登录Microsoft DataMarket后client_secret

然后，请参阅以下文档，了解如何获取access_token＆amp;翻译API。

1. 获取访问令牌，https://msdn.microsoft.com/en-us/library/hh454950.aspx
2. 使用HTTP接口https://msdn.microsoft.com/en-us/library/ff512387.aspx
3. 翻译语言代码，https://msdn.microsoft.com/en-us/library/hh456380.aspx

作为参考，这是我的Java库示例代码apache commons-io＆amp; fastjson

package sample;

import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLEncoder;
import java.nio.charset.StandardCharsets;

import org.apache.commons.io.IOUtils;

import com.alibaba.fastjson.JSON;

public class TextTranslatorTest {

    public static String getAccessToken(String charset, String clientId, String clientSecret, String scope,
            String grantType) throws MalformedURLException, IOException {
        String url = "https://datamarket.accesscontrol.windows.net/v2/OAuth2-13";
        String paramsTemplate = "client_id=%s&client_secret=%s&scope=%s&grant_type=%s";
        String params = String.format(paramsTemplate, URLEncoder.encode(clientId, charset),
                URLEncoder.encode(clientSecret, charset), scope, grantType);
        System.out.println(url);
        HttpURLConnection conn = (HttpURLConnection) new URL(url).openConnection();
        conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=" + charset);
        conn.setRequestProperty("Accept-Charset", charset);
        conn.setRequestMethod("POST");
        conn.setDoOutput(true);
        IOUtils.write(params, conn.getOutputStream(), "UTF-8");;
        String resp = IOUtils.toString(conn.getInputStream(), "UTF-8");
        System.out.println(resp);
        String accessToken = JSON.parseObject(resp).getString("access_token");
        return accessToken;
    }

    public static String translate(String charset, String accessToken, String text, String from, String to) throws MalformedURLException, IOException {
        String url = "http://api.microsofttranslator.com/v2/Http.svc/Translate?text=" + URLEncoder.encode(text, charset) + "&from=" + from + "&to=" + to;
        HttpURLConnection conn = (HttpURLConnection) new URL(url).openConnection();
        conn.setRequestProperty("Authorization", "Bearer" + " " + accessToken);
        String resp = IOUtils.toString(conn.getInputStream(), "UTF-8");
        return resp;
    }

    public static void main(String[] args) throws MalformedURLException, IOException {
        String charset = StandardCharsets.UTF_8.name();
        String clientId = "peter-translator-test";
        String clientSecret = "xxxxxxxxxxxxxxxxxx";
        String scope = "http://api.microsofttranslator.com";
        String grantType = "client_credentials";
        String accessToken = getAccessToken(charset, clientId, clientSecret, scope, grantType);
        System.out.println(accessToken);
        String text = "happy";
        String from = "en";
        String to = "de";
        String resp = translate(charset, accessToken, text, from, to);
        System.out.println(resp);
    }
}

请注意，根据页面https://translatorbusiness.uservoice.com/knowledgebase/articles/1078534-microsoft-translator-on-azure，您只需在2017年4月30日之前使用上述答案。然后，您需要按照新文档http://docs.microsofttranslator.com/text-translate.html在Azure上使用Text Translator API。但是Azure上的Text Translator的新服务似乎还没有通过我的测试准备好。所以我只列出以下简单步骤作为参考。

1. 获取Azure访问令牌，请参阅http://docs.microsofttranslator.com/oauth-token.html。要获得<your-key>，您可以参考新文档的第12步到Go to the Keys option and copy your subscription key to access the service。

   //使用标头传递密钥 curl --header'Ocp-Apim-Subscription-Key：' - data“”'https://api.cognitive.microsoft.com/sts/v1.0/issueToken' //使用查询字符串参数传递密钥 curl --data“”'https://api.cognitive.microsoft.com/sts/v1.0/issueToken?Subscription-Key='

2. 要拨打/Translate HTTP接口，请参阅http://docs.microsofttranslator.com/text-translate.html#!/default/get_Translate。
