当通过React-router的链接组件更改URL时,我的路由工作正常。但是,如果我尝试在浏览器中手动更改URL,则会出现404错误。

以下是routes.js文件

import React from "react";
import {Route, Switch, NotFoundRoute} from 'react-router-dom';
import App from "./components/app.jsx";
import HomePage from "./components/homePage.jsx";
import AboutPage from "./components/about/aboutPage.jsx";
import AuthorPage from "./components/authors/authorPage.jsx";
import ManageAuthorPage from "./components/authors/manageAuthorPage.jsx";
import NotFoundPage from "./components/notFoundPage.jsx";

var routes = (
    <App>
        <Switch>
            <Route name="home" exact path="/" component={HomePage} />
            <Route name="authors" exact path="/authors" component={AuthorPage} />
            <Route name="addAuthor" exact path="/author" component={ManageAuthorPage} />
            <Route name="manageAuthor" path="/author/:id" component={ManageAuthorPage} />
            <Route name="about" exact path="/about" component={AboutPage} />
            <Route component={NotFoundPage} />
        </Switch>
    </App>
);

export default routes;

包含BrowserRouter

的main.js文件
import React from 'react';
import ReactDOM from 'react-dom';
import {BrowserRouter} from 'react-router-dom';
import routes from './routes.jsx';
import InitializeActions from './actions/initializeActions';

InitializeActions.initApp();

ReactDOM.render(<BrowserRouter>{routes}</BrowserRouter>, document.getElementById('app'));

以及包含导航栏的header.jsx文件

import React from 'react';
import {Link} from 'react-router-dom';

class Header extends React.Component {
    render() {
        return (
            <nav className="navbar navbar-default">
                <div className="container-fluid">
                    <Link to="/" className="navbar-brand">
                        <img src="../../images/pluralsight-logo.png"/>
                    </Link>
                    <ul className="nav navbar-nav">
                        <li><Link to="/">Home</Link></li>
                        <li><Link to="authors" ref={(comp) => { window.authorsTab=comp }}>Authors</Link></li>
                        <li><Link to="about">About</Link></li>
                    </ul>
                </div>
            </nav>
        );
    }
}

export default Header;

Gulpfile.js

"use strict";

var gulp = require('gulp');
var connect = require('gulp-connect'); //Runs a local dev server
var open = require('gulp-open'); //Opens a URL in a web browser
var browserify = require('browserify'); //Bundle JS
var reactify = require('reactify'); //Transforms react JSX to JS
var source = require('vinyl-source-stream'); //Use-conventional text streams with gulp
var concat = require('gulp-concat'); //concatnates files
var lint = require('gulp-eslint'); //lint our js files including jsx
var babelify = require("babelify");
var browserSync = require("browser-sync");

var config = {
  port: 9005,
  devBaseUrl: 'http://localhost',
  paths: {
    html: './src/*.html',
    js: './src/**/*.js*',
    images: './src/images/*',
    css: [
      'node_modules/bootstrap/dist/css/bootstrap.min.css',
      'node_modules/bootstrap/dist/css/bootstrap-theme.min.css',
      './src/dependencies/*.css',
      'node_modules/toastr/build/toastr.css'
    ],
    dist: './dist',
    mainJs: './src/main.jsx'
  }
}

//start a local dev server
gulp.task('connect', function() {
  connect.server({
    root: ['dist'],
    port: config.port,
    base: config.devBaseUrl,
    livereload: true
  });
});

//opens the URL in browser
gulp.task('open', ['connect'], function() {
  gulp.src('dist/index.html')
    .pipe(open({uri: config.devBaseUrl + ':' + config.port + '/'}));
});

//get all the html files from 'src', bundle them and place inside 'dist' and reload the server
gulp.task('html', function() {
  gulp.src(config.paths.html)
    .pipe(gulp.dest(config.paths.dist))
    .pipe(connect.reload());
});

gulp.task('js', function() {
  browserify(config.paths.mainJs)
    .transform(babelify, {presets: ["es2015", "react"]})
    .bundle()
    .on('error', console.error.bind(console))
    .pipe(source('bundle.js'))
    .pipe(gulp.dest(config.paths.dist + '/scripts'))
    .pipe(connect.reload());
});

gulp.task('css', function() {
  gulp.src(config.paths.css)
    .pipe(concat('bundle.css'))
    .pipe(gulp.dest(config.paths.dist + '/css'));
});

gulp.task('images', function() {
  gulp.src(config.paths.images)
    .pipe(gulp.dest(config.paths.dist + '/images'))
    .pipe(connect.reload());
});

gulp.task('lint', function() {
  return gulp.src(config.paths.js)
    .pipe(lint({configFile: 'eslint.config.json'}))
    .pipe(lint.format());
});

//watch any changes in html files
gulp.task('watch', function() {
  gulp.watch(config.paths.html, ['html']);
  gulp.watch(config.paths.js, ['js', 'lint']);  
  gulp.watch(config.paths.css, ['css']);  
});

//the default task
gulp.task('default', ['html', 'js', 'css', 'images', 'lint', 'open', 'watch']);

我尝试在多个来源上寻找解决方案,但每个人似乎都遵循与我类似的方法! 请看一看。在此先感谢:)

使用BrowserRouter时,您需要在网络包中添加historApiFallback: true

将此添加到您的webpack配置

devServer: {
    historyApiFallback: true,
  },

gulp等价物将是:

historyApiFallback = require('connect-history-api-fallback')


//start a local dev server
gulp.task('connect', function() {
  connect.server({
    root: ['dist'],
    port: config.port,
    base: config.devBaseUrl,
    livereload: true,
    middleware: [ historyApiFallback() ]
  });
});

如果您使用的是webpack-dev-server。设置:

devServer{
  //...
  historyApiFallback: true
}

它将提供&#39; index.html&#39;取代任何404回复...

如果您已发布到server.make确保您的服务器配置将其重定向到主html

快递:

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

吞-连接:

connect.server({
  root: ['dist'],
  port: config.port,
  base: config.devBaseUrl,
  livereload: true,
  fallback: 'index.html'
});

这对我有用:

  var historyApiFallback = require('connect-history-api-fallback');

  gulp.task('connect', function() {
    connect.server({
      root: ['dist'],
      port: config.port,
      base: config.devBaseUrl,
      livereload: true,
      middleware: function(connect, opt) {
        return [
          historyApiFallback({})
        ]
      }
    });
  });
