无法使用 react-router 和 webpack-dev-server 直接进入动态路由 [英] Cannot go directly to dynamic route with react-router and webpack-dev-server

问题描述

启动webpack-dev-server后，可以直接进入静态路由(如http://localhost:3456/one)，但不能直接进入动态路由(如http://localhost:3456/two/1234).

我相信我在 webpack-dev-server 配置中遗漏了一些东西，但不确定是什么.

浏览器控制台输出这个错误:

GET http://localhost:3456/two/dev-bundle.js 404(未找到)拒绝执行来自 'http://localhost:3456/two/dev-bundle.js' 的脚本，因为它的 MIME 类型('text/html')不可执行，并且启用了严格的 MIME 类型检查

webpack.config.js

const path = require("path")const HtmlWebpackPlugin = require('html-webpack-plugin');const webpack = require("webpack")模块.出口 = {模式:发展"，开发工具:评估源地图"，入口: ["./index.js",],输出: {文件名:dev-bundle.js"，},模块: {规则: [{测试:/\.jsx?$/,loader: "babel-loader",排除:/node_modules/，},],},插件: [新的 HtmlWebpackPlugin({模板:path.join(__dirname, "dev.html")}),新的 webpack.NamedModulesPlugin(),新的 webpack.HotModuleReplacementPlugin()],开发服务器:{historyApiFallback: 真,热:真的，端口:3456，统计数据:最小"}}

app.js

import React, { Component } from "react"从react-hot-loader"导入{热}import { BrowserRouter as Router, Switch, Route } from "react-router-dom"从./components/ComponentOne"导入 ComponentOne从./components/ComponentTwo"导入 ComponentTwoconst MyApp = () =>(<div><路由器><开关><路由精确路径="/" component={ComponentOne}/><路由精确路径="/one" component={ComponentOne}/><Route path="/two/:id" component={ComponentTwo}/></开关></路由器>

)导出默认热(模块)(MyApp)

ComponentTwo.js

import React, { Component } from "react"从react-router-dom"导入{链接}导出默认类 ComponentTwo 扩展组件 {使成为() {返回 (<div><h1>ComponentTwo 用于 {this.props.match.params.id}</h1>

)}}

感谢任何帮助.

解决方案

我能够通过更新 webpack 配置的一部分来解决这个问题:

输出:{文件名:dev-bundle.js"，publicPath: "/",//添加了这一行},

控制台错误仍然存​​在，但至少页面已加载.

After starting webpack-dev-server, I can go directly to a static route (e.g. http://localhost:3456/one), but I cannot go directly to a dynamic route (e.g. http://localhost:3456/two/1234).

I believe I am missing something in my webpack-dev-server config, but not sure what.

The browser console outputs this error:

GET http://localhost:3456/two/dev-bundle.js 404 (Not Found)
Refused to execute script from 'http://localhost:3456/two/dev-bundle.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled

webpack.config.js

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

module.exports = {
  mode: "development",
  devtool: "eval-source-map",
  entry: [
    "./index.js",
  ],
  output: {
    filename: "dev-bundle.js",
  },
  module: {
    rules: [
      {
        test: /\.jsx?$/,
        loader: "babel-loader",
        exclude: /node_modules/,
      },
    ],
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: path.join(__dirname, "dev.html")
    }),
    new webpack.NamedModulesPlugin(),
    new webpack.HotModuleReplacementPlugin()
  ],
  devServer: {
    historyApiFallback: true,
    hot: true,
    port: 3456,
    stats: "minimal"
  }
}

app.js

import React, { Component } from "react"
import { hot } from "react-hot-loader"
import { BrowserRouter as Router, Switch, Route } from "react-router-dom"
import ComponentOne from "./components/ComponentOne"
import ComponentTwo from "./components/ComponentTwo"

const MyApp = () => (
  <div>
    <Router>
      <Switch>
        <Route exact path="/" component={ComponentOne} />
        <Route exact path="/one" component={ComponentOne} />
        <Route path="/two/:id" component={ComponentTwo} />
      </Switch>
    </Router>
  </div>
)

export default hot(module)(MyApp)

ComponentTwo.js

import React, { Component } from "react"
import { Link } from "react-router-dom"

export default class ComponentTwo extends Component {
  render() {
    return (
      <div>
        <h1>ComponentTwo for {this.props.match.params.id}</h1>
      </div>
    )
  }
}

Any help is appreciated.

解决方案

I was able to resolve this by updating part of the webpack config:

output: {
  filename: "dev-bundle.js",
  publicPath: "/",    // added this line
},

The console error remains, but at least the page loads.
