在dialogflow v2 api中使用app.setContext（）？ [英] app.setContext() in dialogflow v2 api?

问题描述

v2 API中来自v1的dialogflow的app.setContext（）等价于什么？给定迁移指南概述的设置（如下），当在下面的演示代码中触发欢迎意图时，您会打电话（例如）设置上下文？

What is the equivalent of dialogflow's app.setContext() from v1 in the v2 API? Given the setup that the migration guide outlines (below), what call would you make to--for example--set a context when the welcome intent is triggered in the demo code below?

// v2
const functions = require('firebase-functions');
const { dialogflow } = require('actions-on-google');

const app = dialogflow();

app.intent('Default Welcome Intent', conv => {
  conv.ask('How are you?');
});

exports.factsAboutGoogle = functions.https.onRequest(app);

推荐答案

像这样设置上下文：

    const parameters = { // Custom parameters to pass with context
      welcome: true,
    };

    conv.contexts.set('welcome-context', 5, parameters);

第二个参数是上下文寿命。

The second parametr is for context lifespan.

在您的示例代码中：

const functions = require('firebase-functions');
const { dialogflow } = require('actions-on-google');

const app = dialogflow();

app.intent('Default Welcome Intent', conv => {
  conv.ask('How are you?');
  const parameters = { // Custom parameters to pass with context
      welcome: true,
    };
  conv.contexts.set('welcome-context', 5, parameters);
});

exports.factsAboutGoogle = functions.https.onRequest(app);

然后，您可以使用以下内容访问上下文：

Then you can access the contexts with:

const contexts = conv.contexts;
