不带正则表达式的ASP.NET Core 2.1中的URL重写 [英] URL rewriting in ASP.NET Core 2.1 without regex

问题描述

我的收藏夹图标位于/images/favicon.ico，而不是根目录.在Startup.cs中，我可以添加重定向以避免404:

My favicon is at /images/favicon.ico rather than the root. In Startup.cs I can added a redirect to avoid a 404:

app.UseRewriter(new RewriteOptions()
  .AddRedirect("favicon.ico", "images/favicon.ico"));

这很好用，但是当然要依赖重定向. 文档还显示了如何使用重写，因此用户看不到重定向.

That works nicely, but of course relies on a redirect. The docs also show how to use rewriting, so the user doesn't see a redirect.

我尝试了这个，但是得到了404:

I tried this, but get a 404:

app.UseRewriter(new RewriteOptions()
  .AddRewrite("favicon.ico", "images/favicon.ico", skipRemainingRules:true));

所以我认为也许我需要使用一个虚拟正则表达式:

So I thought that maybe I need to use a dummy regex:

app.UseRewriter(new RewriteOptions()
  .AddRewrite("^(favicon.ico)$", "images/favicon.ico", skipRemainingRules:true));

但是我仍然得到404.我该如何进行这项工作?

But I still get a 404. How do I make this work?

推荐答案

根据 Ionix的答案，重写规则必须在调用UseStaticFiles()

As per Ionix's answer, the rewrite rules must be applied before the call to UseStaticFiles()

旧答案，不再相关

按照您的问题，我已经使用AddRewrite方法进行了很多测试，并且尝试了许多受

Following your question I've done a lot of testing with the AddRewrite method and I've tried a lot of things inspired by the official documentation but nothing worked. At best I got a redirect ...

所以我的答案是:你不能！仅重定向有效.如果您找到一种方法来进行真正的重写，请告诉我，但就目前而言，我认为这是不可能的.

So my answer is: you can't ! Only a redirect works. If you find a way to make a true rewrite work, please let me know but for now I'll consider this is impossible.

为什么不简单地使用有效的解决方案重定向?您需要重写吗?

Why not simply use the working solution, the redirect ? Do you need a rewrite ?
