Webpack开发服务器有一个选项可以启用此功能。打开包。Json和添加——history-api-fallback。 这个解决方案对我很有效。

我也遇到过同样的问题，这个解决方案对我们很有效……

背景:

我们在同一台服务器上托管多个应用程序。当我们刷新服务器时，它不知道该在目标文件夹的哪个位置查找特定应用程序的索引。上面的链接将把你带到我们的工作…

我们正在使用:

文件package.json:

"dependencies": {
  "babel-polyfill": "^6.23.0",
  "ejs": "^2.5.6",
  "express": "^4.15.2",
  "prop-types": "^15.5.6",
  "react": "^15.5.4",
  "react-dom": "^15.5.4",
  "react-redux": "^5.0.4",
  "react-router": "^3.0.2",
  "react-router-redux": "^4.0.8",
  "redux": "^3.6.0",
  "redux-persist": "^4.6.0",
  "redux-thunk": "^2.2.0",
  "webpack": "^2.4.1"
}

我的webpack.config.js文件:

/* eslint-disable */
const path = require('path');
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const babelPolyfill = require('babel-polyfill');
const HTMLWebpackPluginConfig = new HtmlWebpackPlugin({
  template: __dirname + '/app/views/index.html',
  filename: 'index.html',
  inject: 'body'
});

module.exports = {
  entry: [
    'babel-polyfill', './app/index.js'
  ],
  output: {
    path: __dirname + '/dist/your_app_name_here',
    filename: 'index_bundle.js'
  },
  module: {
    rules: [{
      test: /\.js$/,
      loader: 'babel-loader',
      query : {
          presets : ["env", "react", "stage-1"]
      },
      exclude: /node_modules/
    }]
  },
  plugins: [HTMLWebpackPluginConfig]
}

我的index.js文件

import React from 'react'
import ReactDOM from 'react-dom'
import Routes from './Routes'
import { Provider } from 'react-redux'
import { createHistory } from 'history'
import { useRouterHistory } from 'react-router'
import configureStore from './store/configureStore'
import { syncHistoryWithStore } from 'react-router-redux'
import { persistStore } from 'redux-persist'

const store = configureStore();

const browserHistory = useRouterHistory(createHistory) ({
  basename: '/your_app_name_here'
})
const history = syncHistoryWithStore(browserHistory, store)

persistStore(store, {blacklist: ['routing']}, () => {
  console.log('rehydration complete')
})
// persistStore(store).purge()

ReactDOM.render(
    <Provider store={store}>
      <div>
        <Routes history={history} />
      </div>
    </Provider>,
  document.getElementById('mount')
)

我的app.js文件:

var express = require('express');
var app = express();

app.use(express.static(__dirname + '/dist'));
// app.use(express.static(__dirname + '/app/assets'));
app.set('views', __dirname + '/dist/your_app_name_here');
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');

app.get('/*', function (req, res) {
    res.render('index');
});

app.listen(8081, function () {
  console.log('MD listening on port 8081!');
});

通过以下对nginx配置的简单更改，我能够克服硬刷新web应用程序中断和手动URL输入web应用程序中断。

React版本:17.0.2 Web服务器:nginx 操作系统:Ubuntu Server 20.04 (Focal Fossa)

之前

location / {
    try_files $uri $uri/ =404;
}

后

location / {
    try_files $uri /index.html;
}

也许还有其他的解决方法，但是这个方法对我来说非常快速和节省时间。

为乔舒亚·戴克的答案添加更多信息。

如果你正在使用Firebase，并且想同时使用根路由和子目录路由，你需要在你的Firebase .json中添加以下代码:

{
  "hosting": {
    "rewrites": [
      {
        "source": "*",
        "destination": "/index.html"
      },
      {
        "source": "/subdirectory/**",
        "destination": "/subdirectory/index.html"
      }
    ]
  }
}

例子:

你正在为客户建立一个网站。您希望网站的所有者在https://your.domain.com/management中添加信息，而网站的用户将导航到https://your.domain.com。

在这种情况下，您的火源。Json文件是这样的:

{
  "hosting": {
    "rewrites": [
      {
        "source": "*",
        "destination": "/index.html"
      },
      {
        "source": "/management/**",
        "destination": "/management/index.html"
      }
    ]
  }
}

将此添加到webpack.config.js:

devServer: {
    historyApiFallback: true
}

刷新DOM组件后无法得到403错误，这很简单。

只需在Webpack配置中添加这一行，'historyApiFallback: true '。这帮了我一整天的忙。
