Watson Speech to Text - 状态：401，错误：未经授权

Question

我正在尝试在我的聊天机器人中集成语音到文本服务，但收到标题中提到的错误。我只是使用了文档中描述的服务。他们将授权方法从用户名+密码更改为api密钥对吗？ 这是我得到的错误：

不过，这就是我的代码的样子：

    SpeechToText stt = new SpeechToText();

    stt.setApiKey("3PHwb6P36A0hgiovasdcqgesVyDZEO7awg2L1be");
    stt.setEndPoint("https://stream.watsonplatform.net/speech-to-text/api");

    try {
        RecognizeOptions recognizeOptions = new RecognizeOptions.Builder()
                  .audio(new File("C:/Users/jvermaet/Desktop/hallo.wav"))
                  .contentType(HttpMediaType.AUDIO_WAV)
                  .build();

        SpeechRecognitionResults srr = stt.recognize(recognizeOptions).execute();
        System.out.println(srr.toString());
                    
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        System.out.println("OO");
    }

我只需要使用 IAmOptions 构造函数。如果您无法导入 IAmOptions，可能是因为您使用的是旧版本的 sdk，这是我的主要问题。

IamOptions options = new IamOptions.Builder()
.apiKey("{apikey}")
.build();
Assistant assistant = new Assistant("{version}", options);
assistant.setEndPoint("{url}");
