选择项目后，Firebase 工具会开始设置 Functions
询问你要使用什么语言使用箭头键进行选择，然后
按 Enter 键继续。
=== Functions Setup A functions directory will be created in your project with a Node.js
package pre-configured. Functions can be deployed with firebase deploy.
? What language would you like to use to write Cloud Functions? (Use arrow keys)
> JavaScript
TypeScript
选择是否要使用 ESLint 捕获可能出现的 bug 并强制执行样式
输入 Y 或 N：
? Do you want to use ESLint to catch probable bugs and enforce style? (Y/n)
在提示符中输入 Y 来获取项目依赖项：
? Do you want to install dependencies with npm now? (Y/n)
设置完成后，您将看到类似于以下内容的输出：
✔ Firebase initialization complete!
安装 actions-on-google 依赖项：
cd <cloud_function_dir>/functions
npm install actions-on-google
获取 fulfillment 依赖项并部署 fulfillment 函数：
npm install
firebase deploy --only functions
部署需要几分钟时间。完成后，您将看到
与以下代码类似。您需要输入函数网址
Dialogflow。
✔ Deploy complete! Project Console: https://console.firebase.google.com/project/exampleproject-123/overview
Function URL (cloudFunctionName): https://us-central1-exampleproject-123.cloudfunctions.net/cloudFunctionName

Note that the final\nsteps in the process below differ based on whether you use Dialogflow or the\nActions SDK.\n| **Note:** Your fulfillment must respond within 5 seconds or the Assistant ends your conversation due to a timeout.\n\nDeploy to Cloud Functions for Firebase\n--------------------------------------\n\n1. [Download and install Node.js](https://nodejs.org/).\n2. Set up and initialize the Firebase CLI. If the following command fails with\n an `EACCES` error, you may need to\n [change npm permissions](https://docs.npmjs.com/getting-started/fixing-npm-permissions).\n\n npm install -g firebase-tools\n\n3. Authenticate the Firebase tool with your Google account:\n\n firebase login\n\n4. Navigate to your Action project directory and initialize Firebase. You'll be\n asked to select which Firebase CLI features you want to set up for your\n Actions project. Choose `Functions` and other features you might want to use,\n like Firestore, then press Enter to confirm and continue:\n\n cd \u003ccloud_function_dir\u003e\n firebase init\n\n5. Associate the Firebase tool with your Actions project by selecting it using\n the arrow keys to navigate the projects list:\n\n | **Note:** You can skip this step by selecting **\\[don't setup a default project\\]** , but then you will need to do this association later using the command **firebase use --project**.\n6. After choosing the project, the Firebase tool starts the Functions setup\n asking you what language you want to use. Select using the arrow keys and\n press Enter to continue.\n\n ```\n === Functions Setup\n\n A functions directory will be created in your project with a Node.js\n package pre-configured. Functions can be deployed with firebase deploy.\n\n ? What language would you like to use to write Cloud Functions? (Use arrow keys)\n \u003e JavaScript\n TypeScript\n ```\n7. Choose if you want to use ESLint to catch probable bugs and enforce style\n typing `Y` or `N`:\n\n ```\n ? Do you want to use ESLint to catch probable bugs and enforce style? (Y/n)\n ```\n8. Get the project dependencies by typing `Y` to the prompt:\n\n ```\n ? Do you want to install dependencies with npm now? (Y/n)\n ```\n\n Once the setup is completed, you'll see an output similar to the following: \n\n ```\n ✔ Firebase initialization complete!\n ```\n9. Install the **actions-on-google** dependency:\n\n cd \u003ccloud_function_dir\u003e/functions\n npm install actions-on-google\n\n10. Get the fulfillment dependencies and deploy the fulfillment function:\n\n npm install\n firebase deploy --only functions\n\n The deployment takes a few minutes. Once completed, you'll see output\n similar to the following. You'll need the **Function URL** to enter in\n Dialogflow. \n\n ```\n ✔ Deploy complete!\n\n Project Console: https://console.firebase.google.com/project/exampleproject-123/overview\n Function URL (cloudFunctionName): https://us-central1-exampleproject-123.cloudfunctions.net/cloudFunctionName\n ```\n\nConnect the webhook to your Action\n----------------------------------\n\n**If you're using Dialogflow:** In the\n[Dialogflow console](https://console.dialogflow.com), go to\n**Fulfillment** , toggle the **Webhook** button to **ENABLED** , and replace\nthe url in the **URL** field with your **Function URL**.\n\n\n**If you're using Actions SDK:** Create an object\ninside the `conversations` object to declare your fulfillment in your Action\npackage: \n\n```text\n{\n \"actions\": [\n {\n \"description\": \"Default Welcome Intent\",\n \"name\": \"MAIN\",\n \"fulfillment\": {\n \"conversationName\": \"myFulfillmentFunction\"\n },\n \"intent\": {\n \"name\": \"actions.intent.MAIN\",\n \"trigger\": {\n \"queryPatterns\": [\n \"talk to myFulfillmentFunction\"\n ]\n }\n }\n }\n ],\n \"conversations\": {\n \"myFulfillmentFunction\": {\n \"name\": \"myFulfillmentFunction\",\n \"url\": \"https://us-central1-myprojectname-ab123.cloudfunctions.net/cloudFunctionName\"\n }\n },\n \"locale\": \"en\"\n}\n```\n| **Note:** You sometimes might want to do development and testing locally on your development machine for quicker iterations. However, your fulfillment must be addressable from the internet. To work around this, you can use a tool like [ngrok](https://ngrok.io), which allows you to create a tunnel from the internet into your development machine. Be aware that this makes your machine vulnerable to attacks, so use caution if you choose this development model."]]
