我正在尝试为我的MVC网络应用程序设置一个API，该应用程序将包含很多路由，但每个路由都有很多相同的部分。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

（观察评论中提供的根问题以及Route names must be unique. You cannot have two different routes named delete. Use deleteLocation and deleteContact instead.之类的下方
我也可以做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：
具有相同名称的属性路线＆＃39;删除＆＃39;必须具有相同的模板：
行动：＆＃39; rest.fais.foo.edu.Controllers.aimContactsController.delete（rest.fais.foo.edu）＆＃39; - 模板：＆＃39;目标/ v1 / contacts / delete / {id}＆＃39;
行动：＆＃39; rest.fais.foo.edu.Controllers.aimLocationsController.delete（rest.fais.foo.edu）＆＃39; - 模板：＆＃39;目标/ v1 / locations / delete / {id}＆＃39;
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?}");
});
}
}
我似乎无法解决如何解决此问题的答案。我想解决当前的问题，但欢迎任何建议。

两个路由的名称相同，这在ASP.NET Core MVC中无效。
我不是在谈论命名的方法，而是关于路由命名。您在Name = "delete"属性中调用了两个标识为HttpPost的路由。 MVC中的路由名称唯一标识路由模板。
从我所看到的，你并不需要确定你的路线，只是为了区分不同的URI。因此，您可以自由删除操作方法的Name属性的HttpPost属性。这应该足以让ASP.NET Core路由器匹配您的操作方法。
如果您只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 ...
}
}

另一个可能的解决方案是：
// other solution
[Route("aim/v1/contacts/[Action]")]
public class aimContactsController : Controller
{
[HttpPost("{id}")]
public IActionResult delete(string id)
{
// omitted ...
}
}

具有动态名称的示例：
[Route("api/{lang}/[controller]/[Action]")]
[ApiController]
public class SpatiaController : ControllerBase
{
private readonly ISpatialService _service;
private readonly ILogger<SpatialController> _logger;
public SpatialUnitsIGMEController(ILogger<SpatialController> logger, ISpatialService service)
{
_service = service;
_logger = logger;
}
[HttpGet]
public async Task<ActionResult<IQueryable<ItemDto>>> Get50k(string lang)
{
var result = await _service.GetAll50k(lang);
return Ok(result);
}
[HttpGet("{name}")]
public async Task<ActionResult<ItemDto>> Get50k(string lang, string name)
{
var result = await _service.Get50k(lang, name);
return Ok(result);
}
}
要调用这些端点，将使用以下调用：
https://example.domain.com/api/en/spatial/get50k->我们用英语获取所有数据
https://example.domain.com/api/en/spatial/get50k/madrid->我们获得了英语的马德里数据
https://example.domain.com/api/es/spatial/get50k/madrid->我们获得了西班牙语的马德里数据
