在多个意图之间传递参数会触发Dialogflow的实现

Question

我有一个Dialogflow代理，该代理已通过Web钩子进行了设置，该钩子从Firebase数据库中提取信息。我试图让不同的意图在数据库上启动不同的查询。座席从“欢迎意图”中请求一个与数据库匹配的名称（例如，您好，很高兴认识您？您要寻找的名称是什么？）。用户从那里得到一个名称，该名称是一个响应，它触发另一个称为“名称”的意图。该意图具有一个名为“ agent.parameters.defaultName”的参数，该参数传递到实现中并用于查询数据库。以下是Webhook的以下脚本启动：

});
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, 
response) => {

const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + 
JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

//function to request bio info on the db
function handleData(agent) {
const congressName = agent.parameters.congressName;
return admin.database().ref().once("value").then((snapshot) => {
var nameInfo = snapshot.child('Name/' + congressName + '/profile').val(); 
agent.add(nameInfo + "\n  \n Tell me the first and last name of the next 
person you'd like to learn about. Or you can say Twitter to get this 
individual's Twitter info.");
});
 }

//Function to return the name's tweet info
function handleTweet(agent) {
const congressName = agent.parameters.congressName;
return admin.database().ref().once("value").then((snapshot) => {
  var nameTweet = snapshot.child('Name/' + congressName + '/twitter_handle').val(); 
  agent.add(nameTweet);
});
}
// Run the proper function handler based on the matched Dialogflow intent 
name
let intentMap = new Map();
intentMap.set('name', handleData);
intentMap.set('name - custom', handleTweet);
agent.handleRequest(intentMap);

});

这将返回简历，并提示用户说出另一个名字或说Twitter来提取Twitter信息。

如果用户说Twitter，我想触发另一个意图。这个Intent也将具有称为DB的实现，但是这次它将拉动Twitter信息。我遇到问题的地方是我无法激发实现的意图。我想知道我的参数是否在正确的部分，或者是否需要弄清楚如何将其传递给Twitter意图。我不确定我要去哪里。

以下是意图：
