Question

我正在尝试使用Microsoft Azure的文本转换器在控制台中构建基本的文本转换器。但是，我的订阅密钥根本不起作用。我已经多次生成它们，以及手动输入它们。请协助。我留下了进一步的说明。感谢您的阅读和帮助。

代码生成此错误：

请尝试下面的代码，它对我有用：

using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
// Install Newtonsoft.Json with NuGet
using Newtonsoft.Json;

    public class TranslationResult
    {
        public DetectedLanguage DetectedLanguage { get; set; }
        public TextResult SourceText { get; set; }
        public Translation[] Translations { get; set; }
    }

    public class DetectedLanguage
    {
        public string Language { get; set; }
        public float Score { get; set; }
    }

    public class TextResult
    {
        public string Text { get; set; }
        public string Script { get; set; }
    }

    public class Translation
    {
        public string Text { get; set; }
        public TextResult Transliteration { get; set; }

            object[] body = new object[] { new { Text = inputText } };
            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", subscriptionKey);

                // 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();
                TranslationResult[] deserializedOutput = JsonConvert.DeserializeObject<TranslationResult[]>(result);
                // Iterate over the deserialized results.
                foreach (TranslationResult o in deserializedOutput)
                {
                    // Print the detected input languge and confidence score.
                    Console.WriteLine("Detected input language: {0}\nConfidence score: {1}\n", o.DetectedLanguage.Language, o.DetectedLanguage.Score);
                    // Iterate over the results and print each translation.
                    foreach (Translation t in o.Translations)
                    {
                        Console.WriteLine("Translated to {0}: {1}", t.To, t.Text);
                    }
                }
            }
        }


        static void Main(string[] args)
        {
            MainAsync(args).GetAwaiter().GetResult();
            Console.ReadKey();
            Console.WriteLine("press anykey to exit");
        }

        static async Task MainAsync(string[] args)
        {

             string route = "/translate?api-version=3.0&to=de&to=it&to=ja&to=th";
            // Prompts you for text to translate. If you'd prefer, you can
            // provide a string as textToTranslate.

            string textToTranslate = "Hello, Tommy.";
            await TranslateTextRequest(subscriptionKey, endpoint, route, textToTranslate);

        }



    }
}

在运行此控制台应用程序之前，请在此处用您自己的键值替换“ subscriptionKey”的值：
