Apache Web 服务器不允许我刷新 on/about，但在 localhost 上它工作正常

Question

我捆绑了我的一个项目，它运行良好。但是，当在路由/about 上点击刷新时，它会显示请求的 URL/about 在此服务器上找不到。但是，当我在 Web 服务器上的本地主机上执行此操作时，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。

这是客户端路由，但我怀疑这是问题

 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>

嘿，这实际上是一件很常见的事情。

发生的情况是，您需要让 apache 服务器忽略任何嵌套路径，而只是将所有请求 /* 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 View 。

这有时在不同的网络服务器中称为“HTML5 模式”。

在 apache 中，执行此操作的方法是添加如下规则:

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

  RewriteRule ^ /index.html [L]

它的作用是告诉 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 find。
