如何在.net core中重写URL？

Question

I would like this mecanism:

• when user try to access to localhost/pro/details/alias => show this page but with tiny url localhost/alias
• when user try to directly access to localhost/alias => show this page with same url localhost/alias
• when user try to access to *localhost/{controller}/{action}/id => show this page as usual

I tried to modify startup.cs

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseBrowserLink();
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
    }

    var rewrite = new RewriteOptions()
        .AddRewrite(@"([a-zA-Z0-9\-]*)", "pro/details/$1", skipRemainingRules: true);

    app.UseRewriter(rewrite);

    app.UseStaticFiles();

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

It works only for the second bullet.

What's wrong with my code? And how to achieve my goal?

Answer 1

Could you try this approach?

 var rewrite = new RewriteOptions()
     .AddRewrite(@"(P|p)ro/(D|d)etails/(.*)", "$1", skipRemainingRules: true);

Answer 2

In order to achieve my goal, I did following stuff :

First I modify my startup.cs like :

app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");

            routes.MapRoute(
                name: "ProfessionnalAlias",
                template: "{id?}",
                defaults: new { controller = "Professionnals", action = "DetailsAlias" });

        });

So I created a new route, after default route in order to target special action : DetailsAlias (see below)

And I also modify my ProfessionnalsController like :

    /// <summary>
    /// This action have an Integer parameter and redirect to action with alias
    /// </summary>
    /// <param name="id"></param>
    /// <returns></returns>
    public async Task<IActionResult> Details(int? id)
    {
        if (id == null)
        {
            return NotFound();
        }

        var professional = await _context.professional 
            .SingleOrDefaultAsync(m => m.id == id);
        if (professional == null)
        {
            return NotFound();
        }

        RedirectResult redirectResult = new RedirectResult("/"+professional.alias);

        return redirectResult;
    }

    /// <summary>
    /// This action show detail view from alias parameter
    /// </summary>
    /// <param name="id"></param>
    /// <returns></returns>
    public async Task<IActionResult> DetailsAlias(string id)
    {
        if (string.IsNullOrEmpty(id))
        {
            return NotFound();
        }

        var professional= await _context.professional.SingleOrDefaultAsync(m => m.alias == id);
        if (professional== null)
        {
            return NotFound();
        }

        return View("Details", professional);
    }

Conclusion :

• If I tried to hit directly /bob => show 'Bob Detail page' with same URL
• If I tried to hit /professional/Details/1 => show 'Bob Detail page' with /bob Url

Thanks for help
