如何使用 IAM 授权授权 IBM Cloud Watson 服务

Question

我正在尝试通过 IBM 云 Java SDK 授权我的 IBM Cloud 语音转文本服务（IAM 授权）。尽管我的 API 密钥和服务 url 是正确的，但我仍然从服务器获得 401 not authorized。

这是我的代码：

IamOptions iamOptions = new IamOptions.Builder().apiKey("dummy-api-key").url("dummy-url").build();
SpeechToText speechToText = new SpeechToText(iamOptions);

这是服务器响应（日志）

我没有包含我的语音合成代码，因为它无关紧要。我检查了 IBM Java 文档和 IAM 文档。这就是他们在 IBM Cloud 中指示授权的方式。

我成功了。您不传递 url 参数，而是将其设置为终点。

IamOptions iamOptions = new IamOptions.Builder().apiKey("ElPOiM4sMnO4CzJq7LEx1h-4dgaQcCNS1WgGYsnNi59D").build();
SpeechToText speechToText = new SpeechToText(iamOptions);
speechToText.setEndPoint("https://gateway-syd.watsonplatform.net/speech-to-text/api");
