Question

在示例应用程序中获取此错误。

java.net.ProtocolException:预期的HTTP101响应，但“401未授权”

使用此代码段进行传输。

TranslateOptions translateOptions = new TranslateOptions.Builder()
                             .addText(params[0])
                             .source(Language.ENGLISH)
                             .target(selectedTargetLanguage)
                             .build();

TranslationResult translationResult = translationService
                             .translate(translateOptions)
                             .execute();

一旦它执行了应用程序，我就会在日志中看到这个错误。

我不太了解watson sdk是如何工作的，但是只要看看我看到的错误：

未经授权的com.ibm.watson.developer_cloud.service.exception.UnauthorizedException：：由于凭据无效而拒绝访问。提示:你设置终点了吗？

是说所提供的凭据无效。你应该从看这个开始。
