java - 如何使用 Azure 在 Java 或 Android 中使用 Microsoft Translator API

Question

我已经在网上搜索了几个小时，寻找 Microsoft 文本翻译 API 的 Android 或 Java 工作示例，因为它是唯一每月免费提供 200 万个字符翻译的 API。但没有任何效果，因为我发现的大部分内容自 2017 年 3 月以来已被弃用，并且现在已迁移到 azure 认知服务。有谁知道该怎么做吗？我在 C# 中找到了一个工作代码，它在控制台中输出翻译，但我无法自己将其转换为 Java，因为我不喜欢 C#。 TIA。

下面是 C# 的工作代码。

using System;
using System.Net.Http;
using System.Threading.Tasks;

namespace AzureSubscriptionKeySample
{
    class Program
    {
        /// Header name used to pass the subscription key to translation service
        private const string OcpApimSubscriptionKeyHeader = "Ocp-Apim-Subscription-Key";

    /// Url template to make translate call
    private const string TranslateUrlTemplate = "http://api.microsofttranslator.com/v2/http.svc/translate?text={0}&from={1}&to={2}&category={3}";

    private const string AzureSubscriptionKey = "MyAzureSubscriptionKey";   //Enter here the Key from your Microsoft Translator Text subscription on http://portal.azure.com

    static void Main(string[] args)
    {
        TranslateAsync().Wait();
        Console.ReadKey();
    }

    /// Demonstrates Translate API call using Azure Subscription key authentication.
    private static async Task TranslateAsync()
    {
        try
        {
            var translateResponse = await TranslateRequest(string.Format(TranslateUrlTemplate, "안녕하세요 친구", "ko", "en", "general"), AzureSubscriptionKey);
            var translateResponseContent = await translateResponse.Content.ReadAsStringAsync();
            if (translateResponse.IsSuccessStatusCode)
            {
                Console.WriteLine("Translation result: {0}", translateResponseContent);
            }
            else
            {
                Console.Error.WriteLine("Failed to translate. Response: {0}", translateResponseContent);
            }
        }
        catch (Exception ex)
        {
            Console.Error.WriteLine("Failed to translate. Exception: {0}", ex.Message);
        }
    }

    public static async Task<HttpResponseMessage> TranslateRequest(string url, string azureSubscriptionKey)
    {
        using (HttpClient client = new HttpClient())
        { 
            client.DefaultRequestHeaders.Add(OcpApimSubscriptionKeyHeader, azureSubscriptionKey);
            return await client.GetAsync(url);
        }
    }
}
}

您可以通过 REST API 使用 Microsoft Translator Text API。

请引用此official doc了解更多详情。

这里我提供了GetTranslations请求的java代码 fragment ，供大家引用。

import org.apache.commons.io.IOUtils;

import javax.net.ssl.HttpsURLConnection;
import java.net.URL;
import java.net.URLEncoder;

public class Test1 {
    private static String key = "<your translator account key>";

    public static void main(String[] args) {
        try {
            // Get the access token
            // The key got from Azure portal, please see https://learn.microsoft.com/en-us/azure/cognitive-services/cognitive-services-apis-create-account
            String authenticationUrl = "https://api.cognitive.microsoft.com/sts/v1.0/issueToken";
            HttpsURLConnection authConn = (HttpsURLConnection) new URL(authenticationUrl).openConnection();
            authConn.setRequestMethod("POST");
            authConn.setDoOutput(true);
            authConn.setRequestProperty("Ocp-Apim-Subscription-Key", key);
            IOUtils.write("", authConn.getOutputStream(), "UTF-8");
            String token = IOUtils.toString(authConn.getInputStream(), "UTF-8");
            System.out.println(token);

//          Using the access token to build the appid for the request url
            String appId = URLEncoder.encode("Bearer " + token, "UTF-8");
            String text = URLEncoder.encode("Hello", "UTF-8");
            String from = "en";
            String to = "fr";
            String translatorTextApiUrl = String.format("https://api.microsofttranslator.com/v2/http.svc/GetTranslations?appid=%s&text=%s&from=%s&to=%s&maxTranslations=5", appId, text, from, to);
            HttpsURLConnection translateConn = (HttpsURLConnection) new URL(translatorTextApiUrl).openConnection();
            translateConn.setRequestMethod("POST");
            translateConn.setRequestProperty("Accept", "application/xml");
            translateConn.setRequestProperty("Content-Type", "text/xml");
            translateConn.setDoOutput(true);
            String TranslationOptions = "<TranslateOptions xmlns=\"http://schemas.datacontract.org/2004/07/Microsoft.MT.Web.Service.V2\">" +
                    "<Category>general</Category>" +
                    "<ContentType>text/plain</ContentType>" +
                    "<IncludeMultipleMTAlternatives>True</IncludeMultipleMTAlternatives>" +
                    "<ReservedFlags></ReservedFlags>" +
                    "<State>contact with each other</State>" +
                    "</TranslateOptions>";
            translateConn.setRequestProperty("TranslationOptions", TranslationOptions);
            IOUtils.write("", translateConn.getOutputStream(), "UTF-8");
            String resp = IOUtils.toString(translateConn.getInputStream(), "UTF-8");
            System.out.println(resp);
        } catch (Exception e) {
            e.printStackTrace();
        }


    }
}

希望对您有帮助。
