Apache Web 服务器不允许我刷新/about 但在 localhost 上它工作正常 [英] Apache web server doesn't allow me to refresh on /about but on localhost its working fine

问题描述

我捆绑了我的一个项目，它运行良好.但是，当在路由/about 上刷新时，它会显示在此服务器上找不到请求的 URL/about .. 但是，当我在我的本地主机上关闭 Web 服务器时，它在刷新和前进/后退按钮上工作正常.我正在使用 react-router 进行客户端路由.

I bundled up one of my projects and it works fine. However when hitting refresh on a route /about, it displays The requested URL /about was not found on this server.. However when I do it on my localhost off a web server it works fine on refresh and forward/back buttons. I'm using react-router for my client side routing.

这里是客户端路由，但我怀疑它的问题

 Router.run(routes, Router.HistoryLocation, function (Handler) {
    React.render(<Handler/>, app);
 });

我的路线就在那里:

let routes = (
<Route>
  <Route name = "App" path="/" handler = {App}>
    <Route name="About" path="/about" handler = {About}/>
    <DefaultRoute name="Projects" handler = {Projects}/>
  </Route>
</Route>
        );

这是我认为我破坏的 APACHE:

<Directory /var/www/>
                # This directive allows us to have apache2's default start page
                # in /apache2-default/, but still have / go to the right place
Require all granted
                #RedirectMatch ^/$ /apache2-default/
        </Directory>

kkotwal.me.conf:

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #
        ServerName kkotwal.me
        ServerAlias www.kkotwal.me
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/kkotwal.me/public_html

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

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

推荐答案

嘿，这其实是很常见的事情.

Hey this is actually a pretty common thing.

发生的事情是你需要让你的 apache 服务器忽略任何嵌套的路径，而是将所有请求 /* 发送到 root.这样你的前端 javascript 就可以在客户端获取路由并显示正确的视图.

What's happening is you need to get your apache server to ignore any nested paths and just send all requests /* to root instead. That way your front-end javascript can pick up the route on the client-side and display the correct view.

这有时在不同的网络服务器中被称为HTML5 模式".

This is sometimes referred to as "HTML5 Mode" in different webservers.

在 apache 中，您这样做的方法是添加如下规则:

In apache the way you do this is add a rule like the following:

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

  RewriteRule ^ /index.html [L]

这样做是告诉 Apache 提供任何存在的文件，但如果它们不存在，则只提供 /index.html 而不是 404 not found.

What this does is to tell Apache to serve any files that exist, but if they dont exist, just serve /index.html rather than a 404 not found.
