没有像 watson 个性洞察演示中那样获取 JSON 输出

Question

使用其 java sdk 构建一个简单的个性洞察 android 应用程序，我无法获得演示中所需的 JSON 输出。

public class Analysis extends AppCompatActivity {

private String textAnalysis;
PersonalityInsights service;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_analysis);

    Intent intent = getIntent();
    textAnalysis = intent.getStringExtra("data");
    Log.i("DATA",textAnalysis+" ff");
    service = new PersonalityInsights();
           service.setUsernameAndPassword(getString(R.string.user_id),getString(R.string.password));


}

@Override
protected void onStart() {
    super.onStart();
    new Thread(new Runnable() {
        @Override
        public void run() {
            Profile profile = service.getProfile(textAnalysis+"").execute();
            Log.i("Analysis",profile.toString());
            Trait trait = profile.getTree();
            Log.i("Analysis","Categories"+trait.getCategory());
            Log.i("Analysis","Name"+trait.getName());
            Log.i("Analysis","Children"+trait.getChildren().get(1).getName());
            Log.i("Analysis","Percentage"+trait.getPercentage());
        }
    }).start();

}
  }                                                                              

但输出与演示不同。它没有 5 大人格特质、需求、价值和其他东西

Answer 1

API 始终返回包含 3 个模型、Big5、需求和价值的配置文件。

在Profile 对象中调用toString() 方法应该打印整个JSON 响应。

我认为这里的问题是您不了解 JSON 输出。看看API Reference，那里描述了JSON输出。

您还可以使用API Explorer 测试 API 并获得实时结果。
