我正在尝试在我的计算机上使用api.ai从google上的actions上运行sillyNameMaker example。 我用express和ngrok隧道建立了一个nodejs服务器。当我尝试在api.ai上向我的代理发送请求时,我的服务器收到POST请求,但是正文似乎是空的。有没有我没有正确设置?
这是我的index.js文件:
'use strict';
var express = require('express')
var app = express()
const ApiAiAssistant = require('actions-on-google').ApiAiAssistant;
function sillyNameMaker(req, res) {
const assistant = new ApiAiAssistant({request: req, response: res});
// Create functions to handle requests here
const WELCOME_INTENT = 'input.welcome'; // the action name from the API.AI intent
const NUMBER_INTENT = 'input.number'; // the action name from the API.AI intent
const NUMBER_ARGUMENT = 'input.mynum'; // the action name from the API.AI intent
function welcomeIntent (assistant) {
assistant.ask('Welcome to action snippets! Say a number.');
}
function numberIntent (assistant) {
let number = assistant.getArgument(NUMBER_ARGUMENT);
assistant.tell('You said ' + number);
}
let actionMap = new Map();
actionMap.set(WELCOME_INTENT, welcomeIntent);
actionMap.set(NUMBER_INTENT, numberIntent);
assistant.handleRequest(actionMap);
function responseHandler (assistant) {
console.log("okok")
// intent contains the name of the intent you defined in the Actions area of API.AI
let intent = assistant.getIntent();
switch (intent) {
case WELCOME_INTENT:
assistant.ask('Welcome! Say a number.');
break;
case NUMBER_INTENT:
let number = assistant.getArgument(NUMBER_ARGUMENT);
assistant.tell('You said ' + number);
break;
}
}
// you can add the function name instead of an action map
assistant.handleRequest(responseHandler);
}
app.post('/google', function (req, res) {
console.log(req.body);
sillyNameMaker(req, res);
})
app.get('/', function (req, res) {
res.send("Server is up and running.")
})
app.listen(3000, function () {
console.log('Example app listening on port 3000!')
})
我得到的错误:
TypeError: Cannot read property 'originalRequest' of undefined

我正在尝试打印req.body,但它未定义...提前感谢您的帮助。

您和Google上的操作包都在假设您如何使用Express。默认情况下,Express会不填充req.body属性(请参阅reference for req.body)。相反,它依赖于其他中间件,例如body-parser。
您应该可以使用
将身体解析器添加到项目中npm install body-parser
然后使用它将请求正文解析为JSON(API.AI发送和使用google上的操作),并在定义app
以将其附加到Express之后立即添加一些其他行:
var bodyParser = require('body-parser');
app.use(bodyParser.json());
