Fulfillment (Dialogflow)
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
您的执行方式逻辑可以使用它在每个请求中收到的语言区域字符串,
迎合用户的需求。本指南将为您介绍如何使用
Cloud Functions for Firebase 中的本地化库,以返回
本地响应。
本地化库
下面是一些值得考虑的实用库
针对特定语言区域生成自定义响应:
创建本地化响应
本部分介绍了如何创建经过本地化的字符串资源文件,
包含本地化的字符串以及如何在 Cloud SQL 中使用这些资源文件
Firebase 执行方式的函数。
如要创建本地化响应,请按以下步骤操作:
- 在
package.json
和 index.js
文件所在的目录中,创建
locales
目录,用于存放本地化字符串文件。我们会将其称为
目录指定为 <project-dir>/functions/locales
。
创建一个资源文件,其中包含已翻译的每个语言区域的本地化字符串
支持的大小。例如,如果您想要支持 en-US
、en-GB
、
以及 de-DE
个语言区域(包含本地化的欢迎和日期消息),这些文件
可能如下所示:
<project-dir>/functions/locales/en-US.json
{
"WELCOME_BASIC": "Hello, welcome!",
"DATE": "The date is %s"
}
<project-dir>/functions/locales/en-GB.json
{
"WELCOME_BASIC": "Hello, welcome!",
"DATE": "The date is %s"
}
<project-dir>/functions/locales/de-DE.json
{
"WELCOME_BASIC": "Hallo und willkommen!",
"DATE": "Das Datum ist %s"
}
在 package.json
文件中,将国际化节点和时刻库声明为
依赖项:
{
...
"dependencies": {
"actions-on-google": "^2.7.0",
"firebase-admin": "^7.2.1",
"firebase-functions": "^2.2.1",
"i18n": "^0.8.3",
"moment": "^2.22.1"
}
}
在 index.js
文件中,声明 i18n 节点和时刻的依赖项
库:
const i18n = require('i18n');
const moment = require('moment');
在 index.js
文件中,使用受支持的语言区域配置 i18n- 节点:
i18n.configure({
locales: ['en-US', 'en-GB', 'de-DE'],
directory: __dirname + '/locales',
defaultLocale: 'en-US'
});
使用客户端库中的 conv.user.locale
为库设置语言区域
属性。
app.middleware((conv) => {
i18n.setLocale(conv.user.locale);
moment.locale(conv.user.locale);
});
如需返回本地化响应,请使用本地化字符串调用 ask()
由 i18n 返回。此代码段还包含一个使用时刻的函数
以返回本地化日期:
app.intent('Default Welcome Intent', (conv) => { // must not be async for i18n
conv.ask(i18n.__('WELCOME_BASIC'));
});
app.intent('date', (conv) => { // must not be async for i18n
conv.ask(i18n.__('DATE', moment().format('LL')));
});
下面是一个完整的 index.js 文件示例:
'use strict';
const {dialogflow} = require('actions-on-google');
const functions = require('firebase-functions');
const i18n = require('i18n');
const moment = require('moment');
i18n.configure({
locales: ['en-US', 'en-GB', 'de-DE'],
directory: __dirname + '/locales',
defaultLocale: 'en-US'
});
const app = dialogflow({debug: true});
app.middleware((conv) => {
i18n.setLocale(conv.user.locale);
moment.locale(conv.user.locale);
});
app.intent('Default Welcome Intent', (conv) => { // must not be async for i18n
conv.ask(i18n.__('WELCOME_BASIC'));
});
app.intent('date', (conv) => { // must not be async for i18n
conv.ask(i18n.__('DATE', moment().format('LL')));
});
exports.demoAction = functions.https.onRequest(app);

This guide shows you how to use some third-party\nlocalization libraries within a Cloud Function for Firebase to return\nlocalized responses.\n\nLocalization libraries\n\nHere are some helpful libraries to consider to help you\ngenerate customized responses for specific locales:\n\n- General purpose: [I18n-node](//github.com/mashpie/i18n-node) (our example code snippets use this library)\n- General purpose: [format.js](//formatjs.io/)\n- Timezone/time localization: [moment.js](//momentjs.com/) (our example code snippets use this library)\n- Money/currency: [numeral.js](//numeraljs.com/)\n\nCreate localized responses\n\nThis section shows you how to create localized string resource files that\ncontain localized strings and how to use these resource files in your Cloud\nFunction for Firebase fulfillment.\n\nTo create localized responses:\n\n1. In the same directory as your `package.json` and `index.js` files, create a `locales` directory for your localized string files. We'll refer to this directory as `\u003cproject-dir\u003e/functions/locales`.\n2. Create a resource file that contains localized strings for every locale that\n you want to support. For example, if you want to support `en-US`, `en-GB`,\n and `de-DE` locales with localized welcome and date messages, those files\n might look like this:\n\n **`\u003cproject-dir\u003e/functions/locales/en-US.json`** \n\n {\n \"WELCOME_BASIC\": \"Hello, welcome!\",\n \"DATE\": \"The date is %s\"\n }\n\n **`\u003cproject-dir\u003e/functions/locales/en-GB.json`** \n\n {\n \"WELCOME_BASIC\": \"Hello, welcome!\",\n \"DATE\": \"The date is %s\"\n }\n\n **`\u003cproject-dir\u003e/functions/locales/de-DE.json`** \n\n {\n \"WELCOME_BASIC\": \"Hallo und willkommen!\",\n \"DATE\": \"Das Datum ist %s\"\n }\n\n3. In the `package.json` file, declare the i18n-node and moment libraries as\n dependencies:\n\n {\n ...\n \"dependencies\": {\n \"actions-on-google\": \"^2.7.0\",\n \"firebase-admin\": \"^7.2.1\",\n \"firebase-functions\": \"^2.2.1\",\n \"i18n\": \"^0.8.3\",\n \"moment\": \"^2.22.1\"\n }\n }\n\n4. In the `index.js` file, declare the dependencies for the i18n-node and moment\n libraries:\n\n ```gdscript\n const i18n = require('i18n');\n const moment = require('moment');\n ```\n\n \u003cbr /\u003e\n\n5. In the `index.js` file, configure the i18n-node with your supported locales:\n\n ```css+lasso\n i18n.configure({\n locales: ['en-US', 'en-GB', 'de-DE'],\n directory: __dirname + '/locales',\n defaultLocale: 'en-US'\n });\n ```\n\n \u003cbr /\u003e\n\n6. Set the locale for the libraries using `conv.user.locale` from the client library\n property.\n\n ```text\n app.middleware((conv) =\u003e {\n i18n.setLocale(conv.user.locale);\n moment.locale(conv.user.locale);\n });\n ```\n\n \u003cbr /\u003e\n\n7. To return a localized response, call `ask()` with a localized string\n returned by i18n. This snippet also contains a function that uses moment\n to return a localized date:\n\n ```scdoc\n app.intent('Default Welcome Intent', (conv) =\u003e { // must not be async for i18n\n conv.ask(i18n.__('WELCOME_BASIC'));\n });\n\n app.intent('date', (conv) =\u003e { // must not be async for i18n\n conv.ask(i18n.__('DATE', moment().format('LL')));\n });\n ```\n\n \u003cbr /\u003e\n\nHere's a complete index.js file as an example: \n\n```gdscript\n'use strict';\nconst {dialogflow} = require('actions-on-google');\nconst functions = require('firebase-functions');\nconst i18n = require('i18n');\nconst moment = require('moment');\n\ni18n.configure({\n locales: ['en-US', 'en-GB', 'de-DE'],\n directory: __dirname + '/locales',\n defaultLocale: 'en-US'\n});\n\nconst app = dialogflow({debug: true});\n\napp.middleware((conv) =\u003e {\n i18n.setLocale(conv.user.locale);\n moment.locale(conv.user.locale);\n});\n\napp.intent('Default Welcome Intent', (conv) =\u003e { // must not be async for i18n\n conv.ask(i18n.__('WELCOME_BASIC'));\n});\n\napp.intent('date', (conv) =\u003e { // must not be async for i18n\n conv.ask(i18n.__('DATE', moment().format('LL')));\n});\n\nexports.demoAction = functions.https.onRequest(app);\n```\n\n\u003cbr /\u003e"]]
