+   若接口调用不成功，建议使用try/catch语句捕获代码中可能出现的错误信息。例如：
+
+    ```
+    try {
+      sensor.once(sensor.sensorType.SENSOR_TYPE_ACCELEROMETER,function(data) {
+          console.info("Data obtained successfully. data=" + data);//获取数据成功，打印对应传感器的数据
+      });
+    } catch (error) {
+      console.error(error);
+    }
+    ```
