反应生产版本404未找到 [英] react production build 404 not found

问题描述

您好，我需要部署React应用.

Hello i need to deploy react app.

要实现这一点，我要运行:"npm run build"

To achieve that i run : "npm run build"

在那之后，我在vhost.conf中添加了vhost

after that in my vhost.conf i've added vhost

<VirtualHost *:80>
ServerName hello.local
DocumentRoot c:/wamp64/www/hello_world/build
<Directory  "c:/wamp64/www/hello_world/build">
             Options Indexes FollowSymLinks MultiViews
             AllowOverride All
             Require all granted
</Directory>

我还添加了etc/hosts hello.local

i've also added to etc/hosts hello.local

我当然已经在httpd.conf中启用了mod重写

of course i've enabled mod rewrite in httpd.conf

当我运行我的react应用程序的hello.local/主页时，显示正确，但是当我想转到react-react路由路径hello.local/example时，我收到404 not found错误.请帮助可能是什么? Apache配置问题或react-router有一些错误?问候

When i run hello.local/ main page of my react app display properly, but when i want to go to react-react route path hello.local/example i received 404 not found error. Please help what can it be ? It's problem with apache configuration or react-router has some mistake ? Regards

推荐答案

这是SPA常见的问题.在SPA中，路由主要发生在客户端.在您的情况下，大多数情况下react-router应该可以完成这项工作.由于整个js捆绑为一个文件并在index.html中提供，因此您需要为服务器中non-existing的所有路径提供index.html.

This is a common issue that comes up for SPA. In SPA, mostly the routing happens on client side. In your case, mostly react-router should be doing the job. Since the whole js is bundled as a single file and is served in index.html, you need to serve index.html for all paths that is non-existing in your server.

您必须添加一个这样的配置

You have to add a config like this

RewriteEngine On  
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^ - [L]

RewriteRule ^ /index.html [L]

因此，如果服务器中没有匹配的路径，则将提供index.html.然后，javascript将执行，react-router(客户端路由)将接管并显示该路由的正确组件.

So, if there is no matching path in your server, the index.html would get served. Then the javascript would execute and react-router(client side routing) will take over and display the correct component for the route.

对于大多数SPA都是如此，因为路由在客户端进行.

This is true for most SPA, where the routing happens on client side.
