google-app-engine - 我如何在 GAE 中设置路由以使用react？在基本 create-react-app 的 GAE 中，通过 URL 直接路由到 react-router-dom 路由失败？

Question

现在回答

这对我来说很难完全正确。通过谷歌的指导方式很少。我希望这对其他人有帮助。

正如 Dan Cornilescu 指出的那样，训练员接受第一场比赛。所以我们从更具体到不太具体。我已经按照 npm run build 创建的文件夹结构解决了这个问题:1.处理js、css、media的子目录。2.处理manifest.json和fav.ico的json和ico请求。3. 将所有其他流量路由到 index.html。

handlers:
  - url: /static/js/(.*)
    static_files: build/static/js/\1
    upload: build/static/js/(.*)
  - url: /static/css/(.*)
    static_files: build/static/css/\1
    upload: build/static/css/(.*)
  - url: /static/media/(.*)
    static_files: build/static/media/\1
    upload: build/static/media/(.*)
  - url: /(.*\.(json|ico))$
    static_files: build/\1
    upload: build/.*\.(json|ico)$
  - url: /
    static_files: build/index.html
    upload: build/index.html
  - url: /.*
    static_files: build/index.html
    upload: build/index.html

欢迎更高效的回答。

Original Question:

Setting GAE app.yaml for react-router routes produces "Unexpected token <" errors.

在开发环境中，所有路由在直接调用时都有效。 localhost:5000 和 localhost:5000/test 产生预期结果。

在 GAE 标准 app.yaml 中，当直接调用 URL www.test-app.com 时，根目录的函数。 www.test-app.com/test 产生 404 错误。

app.yaml #1

runtime: nodejs8
instance_class: F1
automatic_scaling:
  max_instances: 1

handlers:
  - url: /
    static_files: build/index.html
    upload: build/index.html

配置 app.yaml 以接受所有路径的通配符路由失败。 www.test-app.com/和 www.test-app.com/test 产生错误“Unexpected token <”。它似乎正在将 .js 文件作为 index.html 提供。

app.yaml #2

runtime: nodejs8
instance_class: F1
automatic_scaling:
  max_instances: 1

handlers:
  - url: /.*
    static_files: build/index.html
    upload: build/index.html

重现此问题的步骤:

节点:10.15.0npm: 6.4.1

gcloud init 通过 Google Cloud SDK

npm init react-app test-app

npm install react-router-dom

将路由器添加到 index.js:

index.js

import {BrowserRouter as Router, Route} from 'react-router-dom';
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';


ReactDOM.render(
  <Router>
    <App />
  </Router>,
  document.getElementById('root'));
serviceWorker.unregister();

将路由添加到 app.js:

app.js

import {Route} from 'react-router-dom'
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';

class App extends Component {
  render() {
    return (
      <div>
        <Route exact path="/"
          render={() =>  <div className="App">
            <header className="App-header">
              <img src={logo} className="App-logo" alt="logo" />
              <p>
                Edit <code>src/App.js</code> and save to reload.
              </p>
              <a
                className="App-link"
                href="https://reactjs.org"
                target="_blank"
                rel="noopener noreferrer"
              >
                Learn React
              </a>
            </header>
          </div>} />
        <Route exact path="/test"
          render={() =>  <div className="App">
            Hello, World!
          </div>} />
      </div>
    );
  }
}

export default App;

package.json 没有变化:

package.json

{
  "name": "test-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.7.0",
    "react-dom": "^16.7.0",
    "react-router-dom": "^4.3.1",
    "react-scripts": "2.1.3"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

npm 运行构建

gcloud 应用部署

我们如何说服应用引擎允许 React SPA 直接处理路由？

Answer 1

我从 Nathan Shephard 中得到了答案和 Dan Cornilescu并将它们压缩到下面的 app.yaml 中。它似乎适用于我在 GAE 标准上的 React SPA。不需要应用程序服务器(例如:serve.js、ExpressJS 等)。

env: standard
runtime: nodejs10
service: default

handlers:
  - url: /static
    static_dir: build/static

  - url: /(.*\.(json|ico|js))$
    static_files: build/\1
    upload: build/.*\.(json|ico|js)$

  - url: .*
    static_files: build/index.html
    upload: build/index.html
