是否可以使用云功能仿真器在本地测试Dialogflow实现Webhook,如果可以,我应该如何格式化请求?
我已经阅读了所有可以找到的文档,包括位于https://firebase.google.com/docs/functions/local-emulator的指南,尤其令人感兴趣的是之前的这个问题,似乎也有相似之处: Unit test Actions on Google Dialogflow locally
我能够使用函数shell调用我的实现函数,但是,无论我如何尝试格式化主体,我似乎都只能触发后备意图或错误捕获意图。
在给定输入“ hello”的情况下,我可以在Google模拟器上的操作上验证我的Webhook是否成功使用默认的欢迎意图进行响应,但是当使用相同的请求JSON数据作为本地函数的输入时,我将被定向到后备意图。
是不是函数仿真器无法在本地执行适当的意图匹配,因此总是触发后备意图,还是我只是没有正确格式化请求?任何帮助将不胜感激!
这是我正在使用的调用格式,以及来自shell的响应:
firebase > fulfillment({method: 'POST',json: true,body:
require("project/collabrec/testData.json")});
Sent request to function.
firebase > info: User function triggered, starting execution
info: Fallback intent triggered.
info: Execution took 15 ms, user function completed successfully
RESPONSE RECEIVED FROM FUNCTION: 200, {
"payload": {
"google": {
"expectUserResponse": true,
"richResponse": {
"items": [
{
"simpleResponse": {
"textToSpeech": "I didn't quite catch that. Could you say that again?"
}
}
]
}
}
}
}
这是testData.json的内容:
{
"user": {
"userId": "ABwppHFR0lfRsG_UM3NkvAptIkD2iUpIUNxFt-ia05PFuPajV6kRQKXu_H_ECMMe0lP_WcCsK64sH2MEIg8eqA",

},

"availableSurfaces": [

{

},
{

}
]
}
],
"requestType": "SIMULATOR"
}
这是我的云函数webhook:
const {dialogflow, Image} = require('actions-on-google');
const admin = require('firebase-admin');
const functions = require('firebase-functions');
const app = dialogflow();
app.catch((conv, error) => {
console.log("Error intent triggered.")
console.error(error);
conv.ask('Sorry, I ran into an error. Please try that again.');
});
app.fallback((conv) => {
console.log("Fallback intent triggered.")
conv.ask("I didn't quite catch that. Could you say that again?");
})
app.intent('Default Welcome Intent', (conv) => {
console.log("Welcome intent triggered.")
conv.ask("Welcome!!");
});
exports.fulfillment = functions.region('europe-west1').https.onRequest(app);
使用Node v8.1.4和软件包版本:
"@google-cloud/common-grpc": "^0.9.0",
"@google-cloud/firestore": "^0.17.0",
"@google-cloud/functions-emulator": "^1.0.0-beta.5",
"actions-on-google": "^2.4.1",
"firebase-admin": "^6.0.0",
"firebase-functions": "^2.0.5"

问题是您使用的是来自AoG Simulator的JSON,但这显示了AoG正在发送给Dialogflow的JSON。 Dialogflow对此进行处理,并向您的Webhook发送不同的JSON,其中包括处理AoG JSON并确定意图,参数和其他信息的结果。
您正在执行的操作应该可以工作-如果您拥有Dialogflow JSON。您有两种方法可以做到这一点:
最直接的方法是将Webhook运行在可以从Dialogflow接收POST的地方,并查看conv.request
对象,该对象应该能够为您提供所需的JSON。
如果您正在本地开发机上运行webhook(如您建议的那样),我倾向于启动ngrok隧道。隧道提供了一个公共HTTPS服务器,该服务器非常有用,并且具有给我一个控制台的副作用,该控制台可用于准确查看请求和响应JSON的内容。
最后,您应该能够进入Dialogflow中的项目设置并打开Cloud Logging。该日志包含发送到您的Webhook的请求以及从中获得的响应。
