具有不同控制器但具有相同操作名称的路由无法生成所需的URL

Question

我正在尝试为我的MVC网络应用程序设置一个API,它将包含很多路由,但每个路由都有相同的部分.基本上每个区域的CRUD.我也将它设置为版本.我已经设置了两个控制器,每个控制器都有一个简单的操作来启动并立即接收冲突.我得到的错误是

我追随这些网址

• https://foo.bar/aim/v1/contacts/delete/11111
• https://foo.bar/aim/v1/locations/delete/11111
• 等等

MVC会让你拥有一个

• https://foo.bar/home/index/
• https://foo.bar/contacts/index/
• 等等

所以我正在寻找一个不必要地命名的东西,contacts_delete并locations_delete产生像这样的URL

• https://foo.bar/aim/v1/contacts/contacts_delete/11111
• https://foo.bar/aim/v1/locations/locations_delete/11111

• 等等

  (这是在评论中提供的根本问题的观察结果以及以下类似的情况Route names must be unique. You cannot have two different routes named delete. Use deleteLocation and deleteContact instead.)

我不妨这样做,https://foo.bar/aim/v1/contacts_delete/11111但这对我来说似乎毫无意义.如果MVC可以做到这一点,我必须相信有一种方法可以实现这一点.

我得到的错误是:

具有相同名称"delete"的属性路由必须具有相同的模板:

行动:'rest.fais.foo.edu.Controllers.aimContactsController.delete(rest.fais.foo.edu)' - 模板:'aim/v1/contacts/delete/{id}'

行动:'rest.fais.foo.edu.Controllers.aimLocationsController.delete(rest.fais.foo.edu)' - 模板:'aim/v1/locations/delete/{id}'

对于我设置的控制器

[EnableCors("SubDomains")]
[ResponseCache(NoStore = true, Duration = 0)]
[Produces("application/json")]
[Route("aim/v1/contacts/[action]")]
[ProducesResponseType(typeof(errorJson), 500)]
public class aimContactsController : Controller
{
    private readonly IHostingEnvironment _appEnvironment;
    private readonly AimDbContext _aim_context;
    private readonly UserManager<ApplicationUser> _userManager;

    public aimContactsController(IHostingEnvironment appEnvironment,
        AimDbContext aim_context,
        UserManager<ApplicationUser> userManager)
    {
        _appEnvironment = appEnvironment;
        _userManager = userManager;
        _aim_context = aim_context;
    }



    [HttpPost("{id}", Name = "delete")]
    public IActionResult delete(string id)
    {

        return Json(new
        {
            results = "deleted"
        });
    }

}


[EnableCors("SubDomains")]
[ResponseCache(NoStore = true, Duration = 0)]
[Produces("application/json")]
[Route("aim/v1/locations/[action]")]
[ProducesResponseType(typeof(errorJson), 500)]
public class aimLocationsController : Controller
{
    private readonly IHostingEnvironment _appEnvironment;
    private readonly AimDbContext _aim_context;
    private readonly UserManager<ApplicationUser> _userManager;

    public aimLocationsController(IHostingEnvironment appEnvironment,
        AimDbContext aim_context,
        UserManager<ApplicationUser> userManager)
    {
        _appEnvironment = appEnvironment;
        _userManager = userManager;
        _aim_context = aim_context;
    }



    [HttpPost("{id}", Name = "delete")]
    public IActionResult delete(string id)
    {

        return Json(new
        {
            results = "deleted"
        });
    }

}

对于Startup.cs我有

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        loggerFactory.AddConsole(Configuration.GetSection("Logging"));
        loggerFactory.AddDebug();
        //RolesData.SeedRoles(app.ApplicationServices).Wait();

        app.UseApplicationInsightsRequestTelemetry();

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseDatabaseErrorPage();
            app.UseBrowserLink();
        }
        else
        {
            //app.UseExceptionHandler("/Home/Error");
        }

        app.UseIdentity();
        app.UseDefaultFiles();
        app.UseStaticFiles();

        //app.UseResponseCompression();

        // Add external authentication middleware below. To configure them please see http://go.microsoft.com/fwlink/?LinkID=532715
        app.UseSession();

        // custom Authentication Middleware
        app.UseWhen(x => (x.Request.Path.StartsWithSegments("/aim_write", StringComparison.OrdinalIgnoreCase) || x.Request.Path.StartsWithSegments("/rms", StringComparison.OrdinalIgnoreCase)),
        builder =>
        {
            builder.UseMiddleware<AuthenticationMiddleware>();
        });

        // Enable middleware to serve generated Swagger as a JSON endpoint.
        app.UseSwagger();

        // Enable middleware to serve swagger-ui (HTML, JS, CSS etc.), specifying the Swagger JSON endpoint.
        app.UseSwaggerUI(c =>
        {
            c.RoutePrefix = "docs";
            //c.SwaggerEndpoint("/docs/v1/wsu_restful.json", "v1.0.0");swagger
            c.SwaggerEndpoint("/swagger/v1/swagger.json", "v1.0.0");
        });


        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "javascript",
                template: "javascript/{action}.js",
                defaults: new { controller = "mainline" });
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
            routes.MapRoute(
                name: "AIMApi",
                template: "aim/v1/{action}/{id?}",
                defaults: new { controller = "aim" });
            routes.MapRoute(
                name: "AIMContactsApi",
                template: "aim/v1/contacts/{action}/{id?}",
                defaults: new { controller = "aimContactsController" }
            );
            routes.MapRoute(
                name: "AIMLocationsApi",
                template: "aim/v1/locations/{action}/{id?}",
                defaults: new { controller = "aimLocationsController" }
            );
            routes.MapRoute(
                name: "RMSApi",
                template: "{controller=rms}/v1/{action}/{id?}");
        });
    }
}

我似乎无法谷歌答案如何解决这个问题.我想解决眼前的问题,但欢迎任何建议.

您的两个路由都命名相同,这在ASP.NET Core MVC中不起作用.

我不是在谈论命名方法,而是关于路由命名.您Name = "delete"在HttpPost属性中调用了两个具有相同标识符的路由.MVC中的路由名称唯一标识路由模板.

从我所看到的,你不需要确定你的路线,但只是为了区分不同的URI.因此,您可以自由删除操作方法Name的HttpPost属性属性.这应该足以让ASP.NET Core路由器匹配您的操作方法.

相反,如果您仅使用属性路由进行还原,则最好将控制器更改为以下内容:

// other code omitted for clarity
[Route("aim/v1/contacts/")]
public class aimContactsController : Controller
{
    [HttpPost("delete/{id}")]
    public IActionResult delete(string id)
    {
        // omitted ...
    }
}
