使用 Azure AI 翻译 API

本操作指南介绍如何使用翻译器服务 REST API。 你将从基本示例开始,逐步完成在开发过程中常用的一些核心配置选项,其中包括:

先决条件

  • Azure 订阅 - 免费创建订阅

  • Azure AI 多服务或翻译资源。 获得 Azure 订阅后,在 Azure 门户中创建单服务多服务资源以获取密钥和终结点。 部署后,选择”转到资源”。

  • 可以使用免费定价层 (F0) 试用该服务,然后再升级到付费层进行生产。

  • 需要从资源获取密钥和终结点,以便将应用程序连接到翻译器服务。 稍后将密钥和终结点粘贴到代码示例中。 可以在 Azure 门户的“密钥和终结点”页面上找到这些值:

    屏幕截图:Azure 门户的“密钥和终结点”页面。

重要

完成后,请记住将密钥从代码中删除,并且永远不要公开发布该密钥。 对于生产来说,请使用安全的方式存储和访问凭据,例如 Azure Key Vault。 有关详细信息,请参阅 Azure AI 服务安全性

标头

若要通过 REST API 调用翻译器服务,需要确保每个请求包含以下标头。 别担心,我们会在以下部分的示例代码中包括标头。

标头 条件
Ocp-Apim-Subscription-Key Azure 门户中的翻译器服务密钥。
  • 必需
Ocp-Apim-Subscription-Region 创建资源的区域。
  • 使用 Azure AI 多服务或区域(地理)资源(如“美国西部”)时为必需
  • 使用单服务翻译器资源时是可选的。
Content-Type 有效负载的内容类型。 接受的值为 application/jsoncharset=UTF-8
  • 必需
Content-Length 请求正文的长度
  • 可选
X-ClientTraceId 客户端生成的 GUID,用于唯一标识请求。 如果在查询字符串中使用名为 ClientTraceId 的查询参数包括了跟踪 ID,则可以省略此标头。
  • 可选

设置应用程序

  1. 确保使用最新版本的 Visual Studio IDE

    提示

    如果你不熟悉 Visual Studio,请尝试学习 Visual Studio 简介 Learn 模块。

  2. 打开 Visual Studio。

  3. 在“开始”页上,选择“创建新项目”。

    屏幕截图:Visual Studio 开始窗口。

  4. 在“创建新项目”页面上,在搜索框中输入“控制台”。 选择“控制台应用程序”模板,然后选择“下一步”。

    屏幕截图:Visual Studio 的“新建项目”页。

  5. 在“配置新项目”对话框中,在项目名称框中输入 translator_text_app。 将“将解决方案和项目置于同一目录中”复选框保持未选中状态,然后选择“下一步”。

    屏幕截图:Visual Studio 的“配置新项目”对话框窗口。

  6. 在“其他信息”对话框窗口中,确保选择“.NET 6.0 (长期支持)”。 将“不使用顶级语句”复选框保持未选中状态,然后选择“创建”。

    屏幕截图:Visual Studio 的“其他信息”对话框窗口。

使用 NuGet 安装 Newtonsoft.json 包

  1. 右键单击“translator_quickstart”项目并选择“管理 NuGet 包...”。

    NuGet 包搜索框的屏幕截图。

  2. 选择“浏览”选项卡并键入“Newtonsoft”。

    NuGet 包安装窗口的屏幕截图。

  3. 在右侧的包管理器窗口中选择“安装”并将该包添加到项目。

    NuGet 包安装按钮的屏幕截图。

生成应用程序

注意

  • 从 .NET 6 开始,使用 console 模板的新项目将生成与以前版本不同的新程序样式。
  • 新的输出使用最新的 C# 功能,这些功能简化了你需要编写的代码。
  • 使用较新版本时,只需编写 Main 方法的主体。 无需包括顶级语句、全局 using 指令或隐式 using 指令。
  • 有关详细信息,请参阅新的 C# 模板生成顶级语句
  1. 打开 Program.cs 文件。

  2. 删除现有的代码,包括 Console.WriteLine("Hello World!") 行。 将代码示例复制并粘贴到应用程序的 Program.cs 文件中。 对于每个代码示例,请确保使用 Azure 门户翻译器实例中的值更新密钥和终结点变量。

  3. 将所需代码示例添加到应用程序后,选择 formRecognizer_quickstart 旁边的绿色“开始”按钮以生成和运行程序,或按 F5 键

Visual Studio 中“运行程序”按钮的屏幕截图。

重要

本指南中的示例需要硬编码的密钥和终结点。 请记住完成后将密钥从代码中删除永远不要公开发布该密钥。 对于生产环境,请考虑使用安全的方法来存储和访问凭据。 有关详细信息,请参阅 Azure AI 服务安全性

翻译文本

Translator 服务的核心操作是翻译文本。 在本部分,你将生成一个请求,该请求采用单个源 (from) 并提供两个输出 (to)。 然后,我们将查看一些参数,这些参数可用于调整请求和响应。

using System.Text;
using Newtonsoft.Json; // Install Newtonsoft.Json with NuGet

class Program
{
    private static readonly string key = "<YOUR-TRANSLATOR-KEY>";
    private static readonly string endpoint = "https://api.cognitive.microsofttranslator.com";

    // location, also known as region.
    // required if you're using a multi-service or regional (not global) resource. It can be found in the Azure portal on the Keys and Endpoint page.
    private static readonly string location = "<YOUR-RESOURCE-LOCATION>";

    static async Task Main(string[] args)
    {
        // Input and output languages are defined as parameters.
        string route = "/translate?api-version=3.0&from=en&to=sw&to=it";
        string textToTranslate = "Hello, friend! What did you do today?";
        object[] body = new object[] { new { Text = textToTranslate } };
        var requestBody = JsonConvert.SerializeObject(body);

        using (var client = new HttpClient())
        using (var request = new HttpRequestMessage())
        {
            // Build the request.
            request.Method = HttpMethod.Post;
            request.RequestUri = new Uri(endpoint + route);
            request.Content = new StringContent(requestBody, Encoding.UTF8, "application/json");
            request.Headers.Add("Ocp-Apim-Subscription-Key", key);
            // location required if you're using a multi-service or regional (not global) resource.
            request.Headers.Add("Ocp-Apim-Subscription-Region", location);

            // Send the request and get response.
            HttpResponseMessage response = await client.SendAsync(request).ConfigureAwait(false);
            // Read response as a string.
            string result = await response.Content.ReadAsStringAsync();
            Console.WriteLine(result);
        }
    }
}

成功调用后,应会看到以下响应:

[
   {
      "translations":[
         {
            "text":"Halo, rafiki! Ulifanya nini leo?",
            "to":"sw"
         },
         {
            "text":"Ciao, amico! Cosa hai fatto oggi?",
            "to":"it"
         }
      ]
   }
]

可以在 response headers: x-metered-usage 字段中检查每个请求的消耗量(付费的字符数)。

检测语言

如果需要翻译,但不知道文本的语言,可以使用语言检测操作。 可以通过多种方式来识别源文本语言。 本部分介绍如何通过 translate 终结点和 detect 终结点来使用语言检测。

在翻译过程中检测源语言

如果未在翻译请求中包含 from 参数,则翻译器服务会尝试检测源文本的语言。 在响应中,你将获得检测到的语言 (language) 和置信度分数 (score)。 score 越接近 1.0,意味着检测结果正确的置信度越高。

using System;
using Newtonsoft.Json; // Install Newtonsoft.Json with NuGet

class Program
{
    private static readonly string key = "<YOUR-TRANSLATOR-KEY>";
    private static readonly string endpoint = "https://api.cognitive.microsofttranslator.com";

    // location, also known as region.
// required if you're using a multi-service or regional (not global) resource. It can be found in the Azure portal on the Keys and Endpoint page.
    private static readonly string location = "<YOUR-RESOURCE-LOCATION>";

    static async Task Main(string[] args)
    {
        // Output languages are defined as parameters, input language detected.
        string route = "/translate?api-version=3.0&to=en&to=it";
        string textToTranslate = "Halo, rafiki! Ulifanya nini leo?";
        object[] body = new object[] { new { Text = textToTranslate } };
        var requestBody = JsonConvert.SerializeObject(body);

        using (var client = new HttpClient())
        using (var request = new HttpRequestMessage())
        {
            // Build the request.
            request.Method = HttpMethod.Post;
            request.RequestUri = new Uri(endpoint + route);
            request.Content = new StringContent(requestBody, Encoding.UTF8, "application/json");
            // location required if you're using a multi-service or regional (not global) resource. 
            request.Headers.Add("Ocp-Apim-Subscription-Key", key);
            request.Headers.Add("Ocp-Apim-Subscription-Region", location);

            // Send the request and get response.
            HttpResponseMessage response = await client.SendAsync(request).ConfigureAwait(false);
            // Read response as a string.
            string result = await response.Content.ReadAsStringAsync();
            Console.WriteLine(result);
        }
    }
}

成功调用后,应会看到以下响应:

[
   {
      "detectedLanguage":{
         "language":"sw",
         "score":0.8
      },
      "translations":[
         {
            "text":"Hello friend! What did you do today?",
            "to":"en"
         },
         {
            "text":"Ciao amico! Cosa hai fatto oggi?",
            "to":"it"
         }
      ]
   }
]

在不进行翻译的情况下检测源语言

可以使用 Translator 服务来检测源文本的语言,而不进行翻译。 为此,需要使用 /detect 终结点。

using System;
using Newtonsoft.Json; // Install Newtonsoft.Json with NuGet

class Program
{
    private static readonly string key = "<YOUR-TRANSLATOR-KEY>";
    private static readonly string endpoint = "https://api.cognitive.microsofttranslator.com";

    // location, also known as region.
// required if you're using a multi-service or regional (not global) resource. It can be found in the Azure portal on the Keys and Endpoint page.
    private static readonly string location = "<YOUR-RESOURCE-LOCATION>";

    static async Task Main(string[] args)
    {
        // Just detect language
        string route = "/detect?api-version=3.0";
        string textToLangDetect = "Hallo Freund! Was hast du heute gemacht?";
        object[] body = new object[] { new { Text = textToLangDetect } };
        var requestBody = JsonConvert.SerializeObject(body);

        using (var client = new HttpClient())
        using (var request = new HttpRequestMessage())
        {
            // Build the request.
            request.Method = HttpMethod.Post;
            request.RequestUri = new Uri(endpoint + route);
            request.Content = new StringContent(requestBody, Encoding.UTF8, "application/json");
            request.Headers.Add("Ocp-Apim-Subscription-Key", key);
            request.Headers.Add("Ocp-Apim-Subscription-Region", location);

            // Send the request and get response.
            HttpResponseMessage response = await client.SendAsync(request).ConfigureAwait(false);
            // Read response as a string.
            string result = await response.Content.ReadAsStringAsync();
            Console.WriteLine(result);
        }
    }
}

/detect 终结点响应包含替代检测,并指示检测到的所有语言是否都支持翻译和音译。 成功调用后,应会看到以下响应:

[
   {
      "language":"de",

      "score":1.0,

      "isTranslationSupported":true,

      "isTransliterationSupported":false
   }
]

直译文本

音译是指基于拼音相似性将脚本(表音符号系统)中的单词或短语从一种语言转换为另一种语言的过程。 例如,可以使用音译将“สวัสดี”(thai) 转换为“sawatdi”(latn)。 可以通过多种方式来执行音译。 本部分介绍如何通过 translate 终结点和 transliterate 终结点来使用语言检测。

在翻译过程中进行音译

如果要翻译成一种使用不同于源的字母表(或音素)的语言,则可能需要使用音译。 在此示例中,我们将“Hello”从英语翻译为泰语。 除了获得泰语翻译外,还可以使用拉丁字母获得翻译的短语的音译。

若要从 translate 终结点获取音译,请使用 toScript 参数。

注意

有关可用语言和音译选项的完整列表,请参阅语言支持

using System;
using Newtonsoft.Json; // Install Newtonsoft.Json with NuGet

class Program
{
    private static readonly string key = "<YOUR-TRANSLATOR-KEY>";
    private static readonly string endpoint = "https://api.cognitive.microsofttranslator.com";

    // location, also known as region.
   // required if you're using a multi-service or regional (not global) resource. It can be found in the Azure portal on the Keys and Endpoint page.
    private static readonly string location = "<YOUR-RESOURCE-LOCATION>";

    static async Task Main(string[] args)
    {
        // Output language defined as parameter, with toScript set to latn
        string route = "/translate?api-version=3.0&to=th&toScript=latn";
        string textToTransliterate = "Hello, friend! What did you do today?";
        object[] body = new object[] { new { Text = textToTransliterate } };
        var requestBody = JsonConvert.SerializeObject(body);

        using (var client = new HttpClient())
        using (var request = new HttpRequestMessage())
        {
            // Build the request.
            request.Method = HttpMethod.Post;
            request.RequestUri = new Uri(endpoint + route);
            request.Content = new StringContent(requestBody, Encoding.UTF8, "application/json");
            request.Headers.Add("Ocp-Apim-Subscription-Key", key);
            request.Headers.Add("Ocp-Apim-Subscription-Region", location);

            // Send the request and get response.
            HttpResponseMessage response = await client.SendAsync(request).ConfigureAwait(false);
            // Read response as a string.
            string result = await response.Content.ReadAsStringAsync();
            Console.WriteLine(result);
        }
    }
}

成功调用后,应会看到以下响应。 请记住,translate 终结点的响应包含检测到的源语言和一个置信度分数、使用输出语言的字母表的翻译,以及使用拉丁字母的音译。

[
  {
    "detectedLanguage": {
      "language": "en",
      "score": 1
    },
    "translations": [
      {
        "text": "หวัดดีเพื่อน! วันนี้เธอทำอะไรไปบ้าง ",
        "to": "th",
        "transliteration": {
          "script": "Latn",
          "text": "watdiphuean! wannithoethamaraipaiang"
        }
      }
    ]
  }
]

在无翻译的情况下进行音译

你还可以使用 transliterate 终结点来获取音译。 使用音译终结点时,必须提供源语言 (language)、源脚本/字母表 (fromScript) 以及输出脚本/字母表 (toScript) 作为参数。 在此示例中,我们将获取 สวัสดีเพื่อน! วันนี้คุณทำอะไร 的音译。

注意

有关可用语言和音译选项的完整列表,请参阅语言支持

using System;
using Newtonsoft.Json; // Install Newtonsoft.Json with NuGet

class Program
{
    private static readonly string key = "<YOUR-TRANSLATOR-KEY>";
    private static readonly string endpoint = "https://api.cognitive.microsofttranslator.com";

    // location, also known as region.
   // required if you're using a multi-service or regional (not global) resource. It can be found in the Azure portal on the Keys and Endpoint page.
    private static readonly string location = "<YOUR-RESOURCE-LOCATION>";

    static async Task Main(string[] args)
    {
        // For a complete list of options, see API reference.
        // Input and output languages are defined as parameters.
        string route = "/transliterate?api-version=3.0&language=th&fromScript=thai&toScript=latn";
        string textToTransliterate = "สวัสดีเพื่อน! วันนี้คุณทำอะไร";
        object[] body = new object[] { new { Text = textToTransliterate } };
        var requestBody = JsonConvert.SerializeObject(body);

        using (var client = new HttpClient())
        using (var request = new HttpRequestMessage())
        {
            // Build the request.
            request.Method = HttpMethod.Post;
            request.RequestUri = new Uri(endpoint + route);
            request.Content = new StringContent(requestBody, Encoding.UTF8, "application/json");
            request.Headers.Add("Ocp-Apim-Subscription-Key", key);
            // location required if you're using a multi-service or regional (not global) resource.
            request.Headers.Add("Ocp-Apim-Subscription-Region", location);

            // Send the request and get response.
            HttpResponseMessage response = await client.SendAsync(request).ConfigureAwait(false);
            // Read response as a string.
            string result = await response.Content.ReadAsStringAsync();
            Console.WriteLine(result);
        }
    }
}

成功调用后,应会看到以下响应。 与对 translate 终结点的调用不同,transliterate 只返回 text 和输出 script

[
   {
      "text":"sawatdiphuean! wannikhunthamarai",

      "script":"latn"
   }
]

获取句子长度

使用 Translator 服务,你可以获取一个句子或一系列句子的字符计数。 响应以数组的形式返回,包含检测到的每个句子的字符计数。 可以通过 translatebreaksentence 终结点获取句子长度。

在翻译过程中获取句子长度

可以使用 translate 终结点获取源文本和翻译输出的字符计数。 若要返回句子长度(srcSenLentransSenLen),必须将 includeSentenceLength 参数设置为 True

using System;
using Newtonsoft.Json; // Install Newtonsoft.Json with NuGet

class Program
{
    private static readonly string key = "<YOUR-TRANSLATOR-KEY>";
    private static readonly string endpoint = "https://api.cognitive.microsofttranslator.com";

    // location, also known as region.
   // required if you're using a multi-service or regional (not global) resource. It can be found in the Azure portal on the Keys and Endpoint page.
    private static readonly string location = "<YOUR-RESOURCE-LOCATION>";

    static async Task Main(string[] args)
    {
        // Include sentence length details.
        string route = "/translate?api-version=3.0&to=es&includeSentenceLength=true";
        string sentencesToCount =
                "Can you tell me how to get to Penn Station? Oh, you aren't sure? That's fine.";
        object[] body = new object[] { new { Text = sentencesToCount } };
        var requestBody = JsonConvert.SerializeObject(body);

        using (var client = new HttpClient())
        using (var request = new HttpRequestMessage())
        {
            // Build the request.
            request.Method = HttpMethod.Post;
            request.RequestUri = new Uri(endpoint + route);
            request.Content = new StringContent(requestBody, Encoding.UTF8, "application/json");
            request.Headers.Add("Ocp-Apim-Subscription-Key", key);
            // location required if you're using a multi-service or regional (not global) resource.
            request.Headers.Add("Ocp-Apim-Subscription-Region", location);

            // Send the request and get response.
            HttpResponseMessage response = await client.SendAsync(request).ConfigureAwait(false);
            // Read response as a string.
            string result = await response.Content.ReadAsStringAsync();
            Console.WriteLine(result);
        }
    }
}

成功调用后,应会看到以下响应。 除了检测到的源语言和翻译以外,还将为源 (srcSentLen) 和翻译 (transSentLen) 的每个检测到的句子获取字符计数。

[
   {
      "detectedLanguage":{
         "language":"en",
         "score":1.0
      },
      "translations":[
         {
            "text":"¿Puedes decirme cómo llegar a Penn Station? Oh, ¿no estás seguro? Está bien.",
            "to":"es",
            "sentLen":{
               "srcSentLen":[
                  44,
                  21,
                  12
               ],
               "transSentLen":[
                  44,
                  22,
                  10
               ]
            }
         }
      ]
   }
]

在不翻译的情况下获取句子长度

Translator 服务还允许使用 breaksentence 终结点请求句子长度,无需翻译。

using System;
using Newtonsoft.Json; // Install Newtonsoft.Json with NuGet

class Program
{
    private static readonly string key = "<YOUR-TRANSLATOR-KEY>";
    private static readonly string endpoint = "https://api.cognitive.microsofttranslator.com";

    // location, also known as region.
   // required if you're using a multi-service or regional (not global) resource. It can be found in the Azure portal on the Keys and Endpoint page.
    private static readonly string location = "<YOUR-RESOURCE-LOCATION>";

    static async Task Main(string[] args)
    {
        // Only include sentence length details.
        string route = "/breaksentence?api-version=3.0";
        string sentencesToCount =
                "Can you tell me how to get to Penn Station? Oh, you aren't sure? That's fine.";
        object[] body = new object[] { new { Text = sentencesToCount } };
        var requestBody = JsonConvert.SerializeObject(body);

        using (var client = new HttpClient())
        using (var request = new HttpRequestMessage())
        {
            // Build the request.
            request.Method = HttpMethod.Post;
            request.RequestUri = new Uri(endpoint + route);
            request.Content = new StringContent(requestBody, Encoding.UTF8, "application/json");
            request.Headers.Add("Ocp-Apim-Subscription-Key", key);
            // location required if you're using a multi-service or regional (not global) resource.
            request.Headers.Add("Ocp-Apim-Subscription-Region", location);

            // Send the request and get response.
            HttpResponseMessage response = await client.SendAsync(request).ConfigureAwait(false);
            // Read response as a string.
            string result = await response.Content.ReadAsStringAsync();
            Console.WriteLine(result);
        }
    }
}

成功调用后,应会看到以下响应。 与对 translate 终结点的调用不同,breaksentence 只返回名为 sentLen 的数组中源文本的字符计数。

[
   {
      "detectedLanguage":{
         "language":"en",
         "score":1.0
      },
      "sentLen":[
         44,
         21,
         12
      ]
   }
]

字典查找(替代翻译)

使用终结点,可以获取字词或短语的替代翻译。 例如,将单词“sunshine”从 en 翻译成 es 时,此终结点将返回“luz solar”、“rayos solares”和“soleamiento”、“sol”以及“insolación”。

using System;
using Newtonsoft.Json; // Install Newtonsoft.Json with NuGet

class Program
{
    private static readonly string key = "<YOUR-TRANSLATOR-KEY>";
    private static readonly string endpoint = "https://api.cognitive.microsofttranslator.com";

    // location, also known as region.
   // required if you're using a multi-service or regional (not global) resource. It can be found in the Azure portal on the Keys and Endpoint page.
    private static readonly string location = "<YOUR-RESOURCE-LOCATION>";

    static async Task Main(string[] args)

疑难解答

常见的 HTTP 状态代码

HTTP 状态代码 说明 可能的原因
200 OK 请求已成功。
400 错误的请求 必需参数缺失、为空或为 null。 或者,传递给必需参数或可选参数的值无效。 常见问题是标头太长。
401 未授权 请求未授权。 检查确保你的密钥或令牌有效并且在正确的区域中。 另请参阅身份验证
429 请求过多 超出了订阅允许的配额或请求速率。
502 错误的网关 网络或服务器端问题。 也可能表示标头无效。

Java 用户

如果遇到连接问题,可能是因为你的 TLS/SSL 证书已过期。 若要解决此问题,请将 DigiCertGlobalRootG2.crt 安装到专用存储中。
