使用带有秘密的 github 操作来构建/部署 React 应用程序

我正在尝试使用带有秘密的 github 操作来完成构建/部署我的使用 Firebase（目前仅身份验证模块）的 React 应用程序。 对于本地开发，我将 .env 文件与 webpack 和 dotenv-webpack 库一起使用。在本地机器上一切正常。开发服务器从 .env 文件获取环境变量并注入它。但是在 github 操作中构建并在 firebase 托管页面上部署包后，我返回一个错误：

code: "auth/invalid-api-key"
message: "Your API key is invalid, please check you have copied it correctly."

经过一番调查，我发现环境变量没有正确定义：

apiKey: undefined
authDomain: undefined
databaseURL: undefined
messagingSenderId: undefined
projectId: undefined
storageBucket: undefined

主要问题是我是否正确执行变量注入，或者是否有其他方法可以做到这一点？ 我在构建中使用的 webpack 配置：

webpack.build.conf.js

const { merge } = require('webpack-merge');
const baseWebpackConfig = require('./webpack.base.conf');

const buildWebpackConfig = merge(baseWebpackConfig, {
  //!!!
  //CAUTION Production config
  //!!!
  mode: 'production',
});

module.exports = new Promise((resolve, reject) => {
  resolve(buildWebpackConfig);
});

webpack.base.conf.js

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const Dotenv = require('dotenv-webpack');

module.exports = {
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'build'),
    publicPath: '/',
    filename: 'bundle.min.js',
  },
  resolve: {
    extensions: ['.js', '.jsx'],
    alias: {
      '@constants': path.resolve(__dirname, './src/constants'),
      '@components': path.resolve(__dirname, './src/components'),
      '@utils': path.resolve(__dirname, './src/utils'),
      '@styles': path.resolve(__dirname, './src/style'),
    },
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: ['babel-loader', 'eslint-loader'],
      },
      {
        test: /\.less$/,
        use: ['style-loader', 'css-loader', 'less-loader'],
      },
    ],
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: path.resolve('./index.html'),
    }),
    new Dotenv(),
  ],
};

从 .env 文件获取变量的文件：

//Firebase config
export const FB_API_KEY = process.env.REACT_APP_API_FB_KEY;
export const FB_AUTH_DOMAIN = process.env.REACT_APP_FB_AUTH_DOMAIN;
export const FB_DATABASE_URL = process.env.REACT_APP_FB_DATABASE_URL;
export const FB_PROJECT_ID = process.env.REACT_APP_FB_PROJECT_ID;
export const FB_STORAGE_BUCKET = process.env.REACT_APP_STORAGE_BUCKET;
export const FB_MESSAGING_SENDER_ID = process.env.REACT_APP_FB_MESSAGING_SENDER_ID;

管道文件：

name: Firebase Deploy
on:
  push:
    branches:
      - master
jobs:
  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/checkout@master
        env:
          REACT_APP_API_FB_KEY: ${{ secrets.REACT_APP_API_FB_KEY }}
          REACT_APP_FB_AUTH_DOMAIN: ${{ secrets.REACT_APP_FB_AUTH_DOMAIN }}
          REACT_APP_FB_DATABASE_URL: ${{ secrets.REACT_APP_FB_DATABASE_URL }}
          REACT_APP_FB_PROJECT_ID: ${{ secrets.FB_PROJECT_ID }}
          REACT_APP_FB_STORAGE_BUCKET: ${{ secrets.FB_STORAGE_BUCKET }}
          REACT_APP_FB_MESSAGING_SENDER_ID: ${{ secrets.FB_MESSAGING_SENDER_ID }}
      - name: Variable to dotenv
          uses: CallePuzzle/[email protected] /cdn-cgi/l/email-protection
          with:
            variableNamesByFilter: ^REACT_(APP.*)
      - name: Install Dependencies
        run: npm install
      - name: Build
        run: npm run build
      - name: Archive Production Artifact
        uses: actions/upload-artifact@master
        with:
          name: build
          path: build
  deploy:
    name: Deploy
    needs: build
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/checkout@master
      - name: Download Artifact
        uses: actions/download-artifact@master
        with:
          name: build
          path: build
      - name: Deploy to Firebase
        uses: w9jds/firebase-action@master
        with:
          args: deploy --only hosting
        env:
          FIREBASE_TOKEN: ${{ secrets.FIREBASE_TOKEN }}

我找到了解决方案。问题出在Webpack配置。看起来Webpack需要在编译时定义环境变量。为此我用了webpack.DefinePlugin https://webpack.js.org/plugins/define-plugin/

webpack.build.conf.js

const { merge } = require('webpack-merge');
const baseWebpackConfig = require('./webpack.base.conf');
const webpack = require('webpack');

const buildWebpackConfig = merge(baseWebpackConfig, {
  //!!!
  //CAUTION Production config
  //!!!
  mode: 'production',
  plugins: [
    new webpack.DefinePlugin({
      'process.env': {
        REACT_APP_API_FB_KEY: JSON.stringify(process.env.REACT_APP_API_FB_KEY),
        REACT_APP_FB_AUTH_DOMAIN: JSON.stringify(process.env.REACT_APP_FB_AUTH_DOMAIN),
        REACT_APP_FB_DATABASE_URL: JSON.stringify(process.env.REACT_APP_FB_DATABASE_URL),
        REACT_APP_FB_PROJECT_ID: JSON.stringify(process.env.REACT_APP_FB_PROJECT_ID),
        REACT_APP_STORAGE_BUCKET: JSON.stringify(process.env.REACT_APP_STORAGE_BUCKET),
        REACT_APP_FB_MESSAGING_SENDER_ID: JSON.stringify(process.env.REACT_APP_FB_MESSAGING_SENDER_ID),
      },
    }),
  ],
});

module.exports = new Promise((resolve, reject) => {
  resolve(buildWebpackConfig);
});

并且不需要附加 .env 文件。变量在 process.env 中完美传递：

name: Firebase Deploy
on:
  push:
    branches:
      - master
env:
  REACT_APP_API_FB_KEY: ${{ secrets.REACT_APP_API_FB_KEY }}
  REACT_APP_FB_AUTH_DOMAIN: ${{ secrets.REACT_APP_FB_AUTH_DOMAIN }}
  REACT_APP_FB_DATABASE_URL: ${{ secrets.REACT_APP_FB_DATABASE_URL }}
  REACT_APP_FB_PROJECT_ID: ${{ secrets.FB_PROJECT_ID }}
  REACT_APP_FB_STORAGE_BUCKET: ${{ secrets.FB_STORAGE_BUCKET }}
  REACT_APP_FB_MESSAGING_SENDER_ID: ${{ secrets.FB_MESSAGING_SENDER_ID }}
jobs:
  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
      - name: Debug Action
        uses: hmarr/[email protected] /cdn-cgi/l/email-protection
      - name: Checkout Repo
        uses: actions/checkout@master
      - name: Install Dependencies
        run: npm install
      - name: Build
        run: npm run build
      - name: Archive Production Artifact
        uses: actions/upload-artifact@master
        with:
          name: build
          path: build
  deploy:
    name: Deploy
    needs: build
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/checkout@master
      - name: Download Artifact
        uses: actions/download-artifact@master
        with:
          name: build
          path: build
      - name: Deploy to Firebase
        uses: w9jds/firebase-action@master
        with:
          args: deploy --only hosting
        env:
          FIREBASE_TOKEN: ${{ secrets.FIREBASE_TOKEN }}

非常感谢你。
