Watson Developer Java-sdk STT

Question

在示例应用程序中获取此错误。

java.net.ProtocolException：预期HTTP响应101但 '401 没有获得许可'

使用这个代码段transalate。

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

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

一旦它执行的应用程序崩溃，我看到在日志此错误。

D/OkHttp: <-- 401 Not Authorized https://gateway.watsonplatform.net/language-translator/api/v2/translate/v2/translate (413ms, unknown-length body)

我不知道太多关于如何沃森SDK的作品，但只要看一下错误，我看到：

com.ibm.watson.developer_cloud.service.exception.UnauthorizedException： 未经授权：由于证书无效，访问被拒绝。提示： 您设置了端点吗？

是说所提供的凭据是无效的。你应该从看这个开始。
