将子域映射到ASP.Net Core 3中的区域

本文介绍了将子域映射到ASP.Net Core 3中的区域的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

尽可能将我的普通域(例如 example.com )映射到任何区域.
映射我的子域，例如 blog.example.com 转到名为 blog 的区域.

Mapping my normal domain e.g. example.com to no area if possible.
Mapping my subdomain e.g. blog.example.com to a area named blog.

实际上有很多关于该主题的文章，特别是将子域映射到区域.

There are actually quite a lot of posts regarding to this topic, especially mapping subdomains to areas.

从SO:

area-and-subdomain-routing
asp-net-core-mapping-subdomains-to-area

其他:

danylkoweb.com
benjii.me
web.archive.org

可能还有更多.

但是有一个大问题，在ASP.Net Core 3中，他们更改了很多内容，其中之一是常规的路由，请参见 mircosoft的devblog .基本上，他们已对其进行了更改，因此现在所有内容都应该是端点.

But there is one big problem, in ASP.Net Core 3 they changed a lot of things, one of them being the routing in general, see mircosoft's devblog. Basically they changed it so everything should now be endpoints.

所有类，例如 MvcRouteHandler 和接口，例如至少从我的理解来看， IRouter 现在基本上已经过时了.过了一会儿，在GitHub仓库中四处搜寻和挖掘后，我找不到任何有用的东西.

All the classes e.g. MvcRouteHandler and interfaces e.g. IRouter are basically obsolete now, at least from my understanding. After a while googling around and diggin' in the GitHub repositories I couldn't find anything useful.

我正在使用 SDK 3.0.100-preview6-012264 ，但尝试升级到尽快 SDK 3.0.100-preview7-012821 .
我正在使用备用代理(nginx)，它将请求传递给ASP.Net Core Server.

推荐答案

要对整个情况进行更新，随着.Net Core 3的发布，您现在可以使用 RequireHost 方法

To give an update to this whole situation, with the release of .Net Core 3 you can now make use of the RequireHost method.

这看起来类似于以下内容:

This would look something like the following:

app.UseEndpoints(endpoints =>
{
    endpoints.MapAreaControllerRoute(
                name: "Home",
                areaName: "Home",
                pattern: "{controller=Home}/{action=Index}")
             .RequireHost("localhost:5001", "sub.domain.com");
}

如果像示例中那样删除pattern参数中的 Area ，则可以实现该目标.它仍然有些骇人听闻，但干净得多.请注意，您必须在所有端点上放置一个 RequireHost ，以获取正确的默认路由匹配.

If you remove the Area in the pattern parameter, like in the example, you can achieve exactly that. It is still somewhat hacky, but a lot cleaner.Note, that you would have to put a RequireHost on all of the endpoints in order to get proper default route matching.
