Unity IBM Watson Translation，使用具有正确凭证的示例场景不起作用，但也不会显示任何错误消息

Question

我正在使用IBM Watson SDK for Unity（2019.2.11f1）建立一个简单的翻译场景。首先，我尝试了来自ibm watson现场翻译的示例代码，其中的翻译场景已经存在。基本上，您只需要添加IAMKey和我所做的URL。当我开始（播放）场景时，没有任何反应。我没有收到任何错误消息，该错误消息告诉我密钥和URL是正确的，但仍然没有任何反应。

任何人都面临类似的问题，并且知道我做错了什么，或者如果我缺少什么吗？

我尝试过的脚本之一是：

namespace LangaugeTranslatorDemo
{
    public class LanguageTranslatorSample : MonoBehaviour
    {
        #region PLEASE SET THESE VARIABLES IN THE INSPECTOR
        [Space(10)]
        [Tooltip("The service URL (optional). This defaults to \"https://gateway.watsonplatform.net/langauge-translator/api\"")]
        [SerializeField]
        private string serviceUrl;
        [Tooltip("Text field to display the results of translation.")]
        public Text ResultsField;
        [Header("IAM Authentication")]
        [Tooltip("The IAM apikey.")]
        [SerializeField]
        private string iamApikey;
        [Header("Parameters")]
        // https://cloud.ibm.com/apidocs/language-translator#list-models
        [Tooltip("The translation model to use. See https://cloud.ibm.com/apidocs/language-translator#list-models.")]
        [SerializeField]
        private string translationModel;
        #endregion

        private LanguageTranslatorService languageTranslator;

        void Start()
        {
            if (string.IsNullOrEmpty(iamApikey))
                throw new IBMException("Please set the Language Translator iamApikey in the inspector.");
            if (string.IsNullOrEmpty(translationModel))
                throw new IBMException("Please set the translationModel in the inspector.");
            //  Start coroutine to create service
            StartCoroutine(CreateService());
        }

        private IEnumerator CreateService()
        {
            //  Create authenticator
            Authenticator languageTranslatorAuthenticator = new IamAuthenticator(
                apikey: iamApikey,
                url: serviceUrl
                );

            //  Yield here until we have IAM token data
            while (!languageTranslatorAuthenticator.CanAuthenticate())
                yield return null;

            //  Instantiate service
            languageTranslator = new LanguageTranslatorService(
                versionDate: "2019-09-16", 
                authenticator: languageTranslatorAuthenticator
                );
        }

        //  Call this method from ExampleStreaming
        public void Translate(string text)
        {
            //  Array of text to translate
            List<string> translateText = new List<string>();
            translateText.Add(text);

            //  Call to the service
            languageTranslator.Translate(OnTranslate, translateText, translationModel);
            Translate("Hello");
        }

        //  OnTranslate handler
        private void OnTranslate(DetailedResponse<TranslationResult> response, IBMError error)
        {
            //  Populate text field with TranslationOutput
            ResultsField.text = response.Result.Translations[0]._Translation;
        }
    }
}

您需要使用apikey和服务url来进行语音转文本和语言翻译。您可以在检查器的SpeechToTextSample和LangaugeTranslatorSample中添加凭据。
