即使在添加 .htaccess 后，反应应用程序中的 Apache 错误 404 [英] Apache Error 404 in react app even after adding .htaccess

问题描述

我在 /var/www/my_webpage/

中有一个生产反应应用程序(构建文件夹的内容)

这是我的虚拟主机配置

服务器名称 www.domain.comServerAlias domain.comDocumentRoot/var/www/my_webpage错误日志 ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log 合并# 将所有 http 请求重定向到 https - 由 CertBot 自动添加重写引擎开启RewriteCond %{SERVER_NAME} =prudent-solutions.co.in [或]RewriteCond %{SERVER_NAME} =www.prudent-solutions.co.in重写规则 ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]</虚拟主机>

和我的 .htaccess 文件在文档根目录 /var/www/my_webpage

选项 -MultiViews重写引擎开启RewriteCond %{REQUEST_FILENAME} !-f重写规则 ^ index.html [QSA,L]

主页运行良好.但是当我访问 domain.com/some_thing 时，我收到来自 Apache
的 404 错误我浏览了许多有关 React 部署的网站和教程.我不明白他们是如何简单地添加一个 .htaccess 文件并使他们的网站正常工作，以及为什么我没有发生同样的事情.我对 Apache mod_rewrite 完全陌生.

另外，我也不想设置单独的 express.js 服务器来将所有请求路由到 index.html 文件或使用 HashRouter 而不是 BrowserRouter.

我的反应路由器

import "./App.css";//导入 react 组件/页面 ----------------------------------从./components/Misc/Revamp"导入改造；从./Shared/Navbar"导入导航栏；//导入路由需求 ----------import { BrowserRouter as Router, Switch, Route } from react-router-dom";功能应用(){返回 (
<路由器><导航栏/><开关><路由组件={Revamp}/></开关></路由器>
);}导出默认应用程序；

我的manifest.json

解决方案

你需要教你的服务器重定向到 index.html错误 404:

# ...DocumentRoot/var/www/my_webpage<目录"/var/www/my_webpage>AllowOverride 无 # 第 1 行ErrorDocument 404/index.html #第2行:这里我们设置ErrorDocument要求所有授予</目录># ...

现在，您需要重新启动 apache2 服务器.

或者，在项目根目录下的.htaccess文件中添加以下行(不要忘记在上面显示的第1行处AllowOverride ALL):

ErrorDocument 404/index.html

I've a production react app (contents of the build folder) in /var/www/my_webpage/

This is my virtual host config

<VirtualHost *:80>

        ServerName www.domain.com
        ServerAlias domain.com
        DocumentRoot /var/www/my_webpage


        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

# redirect all the http requests to https - added automatically by CertBot
        RewriteEngine on
        RewriteCond %{SERVER_NAME} =prudent-solutions.co.in [OR]
        RewriteCond %{SERVER_NAME} =www.prudent-solutions.co.in
        RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

And my .htaccess file in the document root /var/www/my_webpage

Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.html [QSA,L]

The home page is working fine. But when I go to domain.com/some_thing, I get a 404 Error from Apache
I've went through many websites and tutorials for react deployment. I can't understand how they simply add a .htaccess file and make their website work and why the same is not happening for me. I'm completely new to Apache mod_rewrite.

Also I'm not interested to setup a separate express.js server to route all the requests to index.html file or use HashRouter instead of BrowserRouter.
Screenshot of the error

My react-router

import "./App.css";

// Importing react components/Pages ----------------------------------
import Revamp from "./components/Misc/Revamp";
import Navbar from "./Shared/Navbar";
// Importing Route requirements ----------
import { BrowserRouter as Router, Switch, Route } from "react-router-dom";

function App() {
  return (
    <div className="App">
      <Router>
        <Navbar />
        <Switch>
          <Route component={Revamp} />
        </Switch>
      </Router>
    </div>
  );
}

export default App;

My manifest.json

{
  "short_name": "React App",
  "name": "Create React App Sample",
  "homepage": ".",

解决方案

You need to teach your server to redirect to index.html on error 404:

<VirtualHost *:80>

  # ...

  DocumentRoot /var/www/my_webpage

  <Directory "/var/www/my_webpage">
    AllowOverride None # Line 1
    ErrorDocument 404 /index.html # Line 2: Here we set ErrorDocument
    Require all granted
  </Directory>

  # ...

Now, you need to restart the apache2 server.

Or, add below line in .htaccess file under project root directory (don't forget to AllowOverride ALL at Line 1 shown above):

ErrorDocument 404 /index.html
