Node.js 当信心低于一定水平时，如何发送信息？

我在玩Wit.ai Facebook Messenger示例（）

当用户的信息不被理解时，是否有方法发送预设响应。我在想，当信心低于某个临界值时，如何停止机智的对话

非常感谢您的帮助。谢谢。

如果需要更精细的控制，您可以直接使用Wit API并跳过所有ui

function getIntent(message) {
  var serviceResult = {};
  var url = 'https://api.wit.ai/message?v=20161006&q='+message;
  var options = {
    uri: url,
    qs: {},
    method: 'POST',
    headers: {},
    auth: {'bearer': process.env.WIT_TOKEN},
    json: true
  };
  request(options, function(error, response, body) {
    if(!error) {
      serviceResult.result = "success";
      // Check for entities
      if(body.entities.contact) {
        serviceResult.entity = body.entities.contact[0].value;
        serviceResult.entityConfidence = body.entities.contact[0].confidence;
      }
      // Check for intent
      if(body.entities.intent) {
        serviceResult.intent = body.entities.intent[0].value;
        serviceResult.intentConfidence = body.entities.intent[0].confidence;
      }
    }
    else {
      serviceResult.result = "fail";
    }
  });
}
