Question

我尝试了三个小时，但没有找到任何解决方案。我正在用Android Studio和类似的代码编写代码：

 Assistant assistantservice = new Assistant("2018-02-16");
        assistantservice.setUsernameAndPassword("<ASSISTANT_USERNAME>", "<ASSISTANT_PASSWORD>");

    InputData input = new InputData.Builder(inputmessage).build();
    //Worspaces are now Skills
    MessageOptions options = new MessageOptions.Builder("<SKILL_ID>").input(input).context(context).build();
    MessageResponse response = assistantservice.message(options).execute();

我需要在这里写<ASSISTANT_USERNAME>，<ASSISTANT_PASSWORD>和<SKILL_ID>。但是当我搜索时，我可以看到旧的东西。有人可以帮我吗。我所有的MainActivity代码：

已编辑的MainActivity代码。你能纠正我的错误吗？

Answer 1

您应该创建三个服务-Watson Assistant，语音对文本和文本对语音here，并将凭据传递给代码。

传递凭据的示例代码

textService.setUsernameAndPassword("apikey", "xNChLjpjnrmri9sXZcsb3jaD1qdUA7FTZaj3jM0LfP5T");

如果创建了Watson Assistant服务，则可以单击“管理”下的“启动工具”。

点击技能
通过单击“新建”来创建新技能。使用示例技能。
点击技能名称旁边的三个垂直点，然后选择查看API详细信息
您的用户名将是“ apikey”，并且可以在其中看到密码。
作为Watson Assistant的V1。使用WORKSPACE ID代替SKILL ID。

我如何找到ASSISTANT_USERNAME和ASSISTANT_PASSWORD
