dropwizard 应用程序中的配置更改以使用 react browserHistory [英] Configuration changes in dropwizard application to work with react browserHistory

问题描述

我有一个 react 应用程序在 dropwizard 服务器上运行.bundle.js 在/ui 上提供.当我在/ui 上打开 url 并导航应用程序(并转到/ui/content)时，它工作正常.但是当我尝试刷新像/app/content 这样的特定页面时，它给出了 404.

I have a react app running on a dropwizard server. The bundle.js is served on /ui. When I open the url on /ui and navigate the app(and goto /ui/content), it works fine. But when I try to refresh a specific page like /app/content, it gives a 404.

我了解客户端渲染和服务器端渲染，而且我需要为/ui 执行 GET 调用并在客户端路由其余部分，但我找不到任何相关文档如何在 dropwizard 中做到这一点.

I know about client side rendering and server side rendering and also that I need to do a GET call for /ui and route the rest on client side, but I couldn't find any documentation for how to do it in dropwizard.

我也知道使用 hashHistory 代替 browserHistory 会起作用(因为 url 的哈希部分不会发送到服务器)，但我想知道是否这可以通过 browserHistory 来完成.

I also know using hashHistory in place of browserHistory will work(as the hash part of the url is not sent to the server), but I wanted to know if this can be done with browserHistory.

有关于如何配置 express 服务器的文档，但我找不到 jetty/dropwizard 的任何内容.

There is documentation on how to configure an express sever but I could not find anything for a jetty/dropwizard.

推荐答案

在 Dropwizard 级别，您可以使用 servlet 过滤器来重写 URL.一种流行的实现是 Tucky UrlRewriteFilter.您将按如下方式实现它:

At the Dropwizard level, one thing you can use a use servlet filter to rewrite the URL. One popular implementation is the Tucky UrlRewriteFilter. You would implement it as follows:

1. 使用 Dropwizard 注册过滤器:

1. Register the filter with Dropwizard:

@Override
public void run(ExampleConfiguration configuration, Environment environment) {
    FilterRegistration.Dynamic registration = environment.servlets()
            .addFilter("UrlRewriteFilter", new UrlRewriteFilter());
    registration.addMappingForUrlPatterns(null, true, "/*");
    registration.setInitParameter("confPath", "urlrewrite.xml");
}

将urlrewrite.xml配置文件添加到你的src/main/resources，添加重写规则

Add the urlrewrite.xml configuration file to your src/main/resources, adding a rewrite rule

<urlrewrite>
    <rule>
        <from>^/(?!(api|static/|manifest.json|assets-manifest.json|favicon.ico)).*$</from>
        <to type="forward">/index.html</to>
    </rule>
</urlrewrite>

上述规则规定，如果请求路径与上述正则表达式匹配，则将请求转发到index.html文件.我用来测试的是 create-react-app，其中输出是匹配器中列出的文件很少.这些文件不应转发.

The above rule states that if the request path matches the above regex, then forward the request to the index.html file. What I used to test was the create-react-app, where the output is a few of those files listed in the matcher. Those files should not be forward.

正则表达式使用否定前瞻，所以它就像一个否定.看起来我的意思是如果路径与这些文件匹配，则向前，但实际上恰恰相反.如果您没有使用 create-react-app，那么您的正则表达式看起来会有所不同.关键是要否定你不想转发的文件.

The regex uses a negative lookahead, so it's like a negation. It may look like I'm saying that if the path matches those files, then forward, but it's actually the opposite. If you are not using the create-react-app, then your regex will look different. The point is to negate the files you don't want forwarded.

我整理了一个工作演示.查看 GitHub 存储库.

I put together a working demo. Check out the GitHub repo.
