我对Google Actions documentation about storing data有点困惑，希望有人可以帮助澄清...
文档指出conv.user.storage对象中的数据将“跨会话”保存。我的意思是，如果用户退出对话，则这些值将在下一次与我的操作进行交互时保持不变并可用。这种理解正确吗？
我问的原因是我无法让这种行为在我的行动中发挥作用。
我已经构建了一个简单的动作执行服务（使用Google NodeJS库v2.4.0和Koa v2.5.3上的Actions）。兑现是由Dialogflow中定义的意图触发的（在帐户已与Google登录链接后），并将其值存储在对话存储中。代码如下：
server.js（基本服务器-从本地./actions/目录动态加载操作）
/* Load the environment */
const dotenv = require('dotenv');
const path = require('path');
const packageJson = require('./package.json');
dotenv.config({
silent: true,
path: process.env.ENV_FILE!=undefined && process.env.ENV_FILE.trim()!='' ? path.normalize(process.env.ENV_FILE) : path.join(__dirname, './.env')
});
const SERVER_NAME = process.env.NAME || packageJson.name;
const SERVER_PORT = process.env.PORT||'8080';
const SERVER_HOST = process.env.HOST||'0.0.0.0';
const HANDLERS_PATH = './actions/';
/* Load the dependencies */
const logger = require('utils-general').logger('google-server');
const Koa = require('koa');
const KoaBody = require('koa-body');
const KoaActionsOnGoogle = require('koa-aog');
const fs = require('fs');
const { dialogflow } = require('actions-on-google');
/* Load and initialise the Google Assistant actions */
//Initialise DialogFlow
const action = dialogflow({ debug: process.env.ACTIONS_DEBUG==='true', clientId: process.env.GOOGLE_CLIENT_ID });
//Load the action intent handlers
const handlers = [];
let handlerFiles = fs.readdirSync(HANDLERS_PATH);
handlerFiles.forEach(function loadHandlers(file) {
let handlerImpl = require(HANDLERS_PATH+file);
let handler = {};
handler[handlerImpl.intent] = handlerImpl.action;
handlers.push(handler);
});
//Add the actions intent handlers to DialogFlow
handlers.forEach(item => {
let key = Object.keys(item)[0];
logger.info(`Adding handler for action intent ${key}`);
action.intent(key, item[key]);
});
/* Create the application server to handle fulfilment requests */
logger.info(`Initialising the ${SERVER_NAME} server (port: ${SERVER_PORT}, host: ${SERVER_HOST})`);
//Create the server
const app = new Koa();
//Add default error handler middleware
app.on('error', function handleAppError(err) {
logger.error(`Unhandled ${err.name||'Error'}: ${err.message || JSON.stringify(err)}`);
});
//Add body parsing middleware
app.use(KoaBody({ jsonLimit: '50kb' }));
//Log the request/ response
app.use(async (ctx, next) => {
logger.trace(`REQUEST ${ctx.method} ${ctx.path} ${JSON.stringify(ctx.request.body)}`);
await next();
logger.trace(`RESPONSE (${ctx.response.status}) ${ctx.response.body ? JSON.stringify(ctx.response.body) : ''}`);
});
//Make the action fulfilment endpoint available on the server
app.use(KoaActionsOnGoogle({ action: action }));
/* Start server on the specified port */
app.listen(SERVER_PORT, SERVER_HOST, function () {
logger.info(`${SERVER_NAME} server started at ${new Date().toISOString()} and listening for requests on port ${SERVER_PORT}`);
});
module.exports = app;
storage-read.js（针对“ STORAGE_READ”意图的实现-从会话存储中读取存储的uuid）：
const logger = require('utils-general').logger('google-action-storage-read');
const { SimpleResponse } = require('actions-on-google');
const { getUserId } = require('../utils/assistant-util');
const _get = require('lodash.get');
module.exports = {
intent: 'STORAGE_READ',
action: async function (conv, input) {
logger.debug(`Processing STORAGE_READ intent request: ${JSON.stringify(conv)}`, { traceid: getUserId(conv) });
let storedId = _get(conv, 'user.storage.uuid', undefined);
logger.debug(`User storage UUID is ${storedId}`);
conv.close(new SimpleResponse((storedId!=undefined ? `This conversation contains stored data` : `There is no stored data for this conversation`)));
}
}
storage-write.js（满足“ STORAGE_WRITE”意图-将UUID写入会话存储）：
const logger = require('utils-general').logger('google-action-storage-read');
const { SimpleResponse } = require('actions-on-google');
const { getUserId } = require('../utils/assistant-util');
const _set = require('lodash.set');
const uuid = require('uuid/v4');
module.exports = {
intent: 'STORAGE_WRITE',
action: async function (conv, input) {
logger.debug(`Processing STORAGE_WRITE intent request`, { traceid: getUserId(conv) });
let newId = uuid();
logger.debug(`Writing new UUID to conversation storage: ${newId}`);
_set(conv, 'user.storage.uuid', newId);
conv.close(new SimpleResponse(`OK, I've written a new UUID to conversation storage`));
}
}
此“ STORAGE_WRITE”实现会存储数据并使其在同一会话的各个回合之间可用（即，在同一会话中触发的另一个意图可以读取存储的数据）。但是，当对话关闭时，与同一用户的后续（新）对话无法读取数据（即，当满足“ STORAGE_READ”意图时）-conv.user.storage对象始终为空。
我在我使用的Google帐户/ Home Mini上设置了语音匹配，但是我看不到如何确定语音是否匹配（尽管好像是在开始新的语音匹配时）对话中使用了我的关联帐户）。我在模拟器上也得到了相同的行为。
样品请求/响应（使用模拟器时）如下：

有人可以让我弄清楚我是在误解文档还是在某个地方有错误？
谢谢！

我怀疑您的情况下个人搜索结果已关闭。
您提到您正在Home Mini上进行测试，并且Prisoner能够在设备上复制（在评论中）。
诸如智能扬声器（家用，迷你）和智能显示器之类的共享设备的个人搜索结果默认为禁用。选中this documentation启用它。
请注意，这意味着可以通过设备访问诸如日历条目之类的个人结果。
要检查userStorage是否将持续存在，可以使用GUEST / VERIFIED标志，请参阅documentation here。
