如何使用IAM授权授权IBM服务

Question

我正试图通过IBM授权我的IBM语音到文本服务(IAM授权)。虽然我的API键和服务url是正确的，但我仍然从服务器获得401 not authorized。

这是我的密码：

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)

我没有包括我的语音合成代码，因为它是不相关的。我检查了IBM文档和IAM文档。这就是他们在IBM中指示授权的方式。

我让它起作用了。您不传递url参数，而是将其设置为端点。

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");
