reactjs - 如何在Prod中使用Docker和Nginx运行React？

Question

我正在尝试在Docker Prod envir中运行动态路由，但在控制台检查器/空白页面中却收到404。为了使页面正常工作，我没有注释几行，您将在下面看到。我在网上找到了几个资源，并按照他们的设置进行了精确设置，但是没有用，这里是one。在localhost:3000上运行仅适用于某些页面，但不适用于动态路由...

Answer 1

我认为这个问题可能在这里:

location ~ ^.+\..+$ {
        try_files $uri =404;
}

我不是nginx专家，但是在我看来，它喜欢检查特定请求的位置是否存在适当的文件，如果不存在，则返回404。
对于React应用程序来说，这将是一件坏事，因为它是一个spa，所有请求都应重定向到index.html(js和媒体文件除外)。
我会尝试将其注释掉并查看效果。
如果不起作用，请尝试将 =404放入 index.html
休息看起来不错。
