razor路由： https://www.learnrazorpages.com/razor-pages/routing

netcore 伪静态：https://learn.microsoft.com/zh-cn/aspnet/core/fundamentals/url-rewriting?view=aspnetcore-6.0#rrr

找到3中路由方式

1.program.cs 单一映射，其中伪静态2和3 会冲突，只能路由到一个页面

builder.Services.AddRazorPages().AddRazorPagesOptions(options => {
options.Conventions.AddPageRoute("/news/detail", "/news_{id}.html");//伪静态1
options.Conventions.AddPageRoute("/news/list", "/newslist_{id}.html"); //伪静态2
options.Conventions.AddPageRoute("/news/list", "/newslist_{id}_p{pageIndex}.html");//伪静态3
});

2.program.cs 页面路由模型约定,可以一对多路由，解决上面的冲突问题

//Razor路由映射
builder.Services.AddRazorPages().AddRazorPagesOptions(options => {
//一对多路径
options.Conventions.AddPageRouteModelConvention("/news/list", pm =>
{
var routes = new List<string>()
{
　　"/newslist_{id:int}_p{pageIndex:int}.html",
　　"/newslist_{id}.html"
};
int i = 0;
routes.ForEach(temp =>
{
　　pm.Selectors.Add(new Microsoft.AspNetCore.Mvc.ApplicationModels.SelectorModel()
　　{
　　AttributeRouteModel = new Microsoft.AspNetCore.Mvc.ApplicationModels.AttributeRouteModel()
　　{
　　　　Order = i,
　　　　Name = "news_list_" + i,
　　　　Template = AttributeRouteModel.CombineTemplates("", temp)
　　}
　　});
i++;
});

});

});

3.net core Rewrite https://learn.microsoft.com/zh-cn/aspnet/core/fundamentals/url-rewriting?view=aspnetcore-6.0#rrr

引用Microsoft.AspNetCore.Rewrite

using (StreamReader apacheModRewriteStreamReader =
File.OpenText("ApacheModRewrite.txt"))
using (StreamReader iisUrlRewriteStreamReader =
File.OpenText("IISUrlRewrite.xml"))
{
　　var options = new RewriteOptions()
　　//.AddRedirect("redirect-rule/(.*)", "redirected/$1")
　　//.AddRewrite(@"^rewrite-rule/(\d+)/(\d+)", "rewritten?var1=$1&var2=$2",skipRemainingRules: true)
　　.AddApacheModRewrite(apacheModRewriteStreamReader)
　　.AddIISUrlRewrite(iisUrlRewriteStreamReader)
　　.Add(MethodRules.RedirectXmlFileRequests)
　　.Add(MethodRules.RewriteTextFileRequests);
　　app.UseRewriter(options);
}

附:IISUrlRewrite.xml

<rewrite>
<rules>
<rule name="news_detail_id_typeid" stopProcessing="true">
<match url="^news_(.*)_t(.*).html$" />
<action type="Rewrite" url="/news/detail?id={R:1}&amp;typeId={R:2}" appendQueryString="false"/>
</rule>
<rule name="Rewrite segment to id querystring" stopProcessing="true">
<match url="^news_(.*).html$" />
<action type="Rewrite" url="/news/detail?id={R:1}" appendQueryString="false"/>
</rule>
</rules>
</rewrite>
