我正在尝试使用koa框架上的google动作。 我无法理解在koa中间件中使用AoG构造函数的请求和响应。
这是我的代码:
const Koa = require( 'koa' )
const koaBody = require('koa-body')
const { DialogflowApp } = require('actions-on-google')
const koaApp = new Koa()
koaApp.use(koaBody())
koaApp.use(async (ctx) => {
const googleAssistant = new DialogflowApp({request: ctx.request, response: ctx.response});
const body = ctx.request.body;
console.log(body)
if (!body.result) ctx.throw(400, 'wrong request')
...
const listItems = []
results.forEach((result, i) => {
listItems.push(
googleAssistant.buildOptionItem('Item'+(i+1))
.setTitle(result.title)
.setDescription(result.text)
)
})
const list = googleAssistant.buildList().addItems(listItems)
console.log('Response to Dialogflow (AoG): ' + JSON.stringify(list))
googleAssistant.askWithList('Here some results', list)
})
const PORT = process.env.PORT || 3000
koaApp.listen( PORT, () => {
console.log( `Listening on ${ PORT }` )
} )
在AoG控制台模拟器上尝试它我收到以下错误:
server error TypeError: this.response_.status is not a function

如果我使用json响应而不是.ask()
,它可以正常工作。在AoG请求的情况下,我只是不确定完全json响应格式的Dialogflow实现
