Dialogflow webhook 实现参数无法访问
[英]Dialogflow webhook fulfillment parameter not accessible
问题描述
I want to get input of a parameter in my webhook fulfillment.
我想在我的 webhook 实现中输入一个参数。
Here is the my code:这是我的代码：
const bodyParser = require('body-parser')
var request = require('request-promise-native');
const { dialogflow } = require('actions-on-google');
const assistant = dialogflow({
clientId: "30xxxxx08407-rv9kxxxxxxxxuuq8f9ul2eg.apps.googleusercontent.com"
});
module.exports = (app) => {
const logger = console;
assistant.intent('Sales', conv => {
const pcode = agent.parameters['PCODE'];
console.log(pcode)
const token = '3369708919812376';
const serviceID = '502';
const P_STATE_CD = 'ALL';
const P_FO_CD = 'ALL';
const P_DISTT_CD = 'ALL';
const P_DATE = '16/12/2019';
const P_PRD_GROUP = 'UREA';
const P_PERSONAL_NO = '106296';
var data = {"token" : token,"serviceID" : serviceID,"P_STATE_CD" : P_STATE_CD,"P_FO_CD" : P_FO_CD,"P_DISTT_CD" : P_DISTT_CD,"P_DATE" : P_DATE,"P_PRD_GROUP" : P_PRD_GROUP,"P_PERSONAL_NO" : P_PERSONAL_NO };
var sdata = JSON.stringify(data);
const options = {
method: 'POST',
uri: 'http://Webservice/resources/webservice/service' ,
body: JSON.parse(sdata) ,
json: true
}
return request(options)
.then( body => {
var unit = body
console.log(body)
unit.intent = "Sales"
unit.value1 = unit.saleInfo[0].QMTD
unit.value2 = unit.saleInfo[0].QYTD
unit.value3 = unit.saleInfo[0].O_UOM
unit.value4 = null
unit.value5 = null
delete unit.saleInfo
var unit2 = JSON.stringify(unit)
console.log(unit2)
conv.ask(unit2);
})
.catch( err => {
console.error( err );
conv.ask('Something went wrong. What should I do now?');
});
})
I tried with const pcode = agent.parameters.PCODE but it is not working.我尝试使用const pcode = agent.parameters.PCODE但它不起作用。 Giving me error:给我错误：
ReferenceError: agent is not defined at assistant.intent.conv (/home/dbalounge/GoogleDF/service.js:15:16) at Function.

agent is not defined anywhere in your code, that's why you're getting: agent没有在您的代码中的任何地方定义，这就是为什么您会得到：
ReferenceError: agent is not defined
In any case if you use assistant.parameters won't work either.在任何情况下，如果您使用assistant.parameters也不会起作用。 Dialogflow intent parameters can be accessed through the second argument of .intent callback. Dialogflow 意图参数可以通过.intent回调的第二个参数访问。
assistant.intent('Sales', (conv, params) => {
const pcode = params.PCODE;
/* ... */
})
