默认情况下，ASP.NET Core使用如 http://localhost:5000/HomeIndex 类的大驼峰路由。但是如果想使用小写的路由，并且这些路由用破折号分隔：http://localhost:5000/home-index它们比较常见且一致。
举例.NET常见路由 http://localhost:5000/User/ListPages 想要的效果 http://localhost:5000/user/list-pages
1、如何生成小写的路由可以这样设置
services.ConfigureRouting(setupAction => {
setupAction.LowercaseUrls = true;
});
2、生成带破折号并且小写的路由可以这样设置
[Route("dashboard-settings")]
class DashboardSettings:Controller {
public IActionResult Index() {
// ...
}
}
似乎上面使用特性路由可以解决这个问题。但是我不想使用，因为每个action都要手动去设置，太繁琐也很容易出错。
我想要的效果是在程序中写个扩展类做到可配置处理。
3、解决方案
以下支持Asp.Net Core Version>=2.2
要做到这一点，首先创建SlugifyParameterTransformer类应该如下所示
public class SlugifyParameterTransformer : IOutboundParameterTransformer
{
public string TransformOutbound(object value)
{
// Slugify value
return value == null ? null : Regex.Replace(value.ToString(), "([a-z])([A-Z])", "$1-$2").ToLower();
}
}
3.1 对于Asp.Net Core2.2 MVC:
在StartUp中ConfiregeServices这样配置
services.AddRouting(option =>
{
option.ConstraintMap["slugify"] = typeof(SlugifyParameterTransformer);
});
路由如下配置：
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller:slugify}/{action:slugify}/{id?}",
defaults: new { controller = "Home", action = "Index" });
});
3.2 对于Asp.Net Core2.2 Web API:
在StartUp中ConfiregeServices这样配置
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc(options =>
{
options.Conventions.Add(new RouteTokenTransformerConvention(new SlugifyParameterTransformer()));
}).SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
}
3.3 对于Asp.Net Core>=3.0 MVC:
在StartUp中ConfiregeServices这样配置
services.AddRouting(option =>
{
option.ConstraintMap["slugify"] = typeof(SlugifyParameterTransformer);
});
路由如下配置：
app.UseEndpoints(endpoints =>
{
endpoints.MapAreaControllerRoute(
name: "AdminAreaRoute",
areaName: "Admin",
pattern: "admin/{controller:slugify=Dashboard}/{action:slugify=Index}/{id:slugify?}");
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller:slugify}/{action:slugify}/{id:slugify?}",
defaults: new { controller = "Home", action = "Index" });
});
3.4 对于Asp.Net Core>=3.0 Web API:
在StartUp中ConfiregeServices这样配置
services.AddControllers(options =>
{
options.Conventions.Add(new RouteTokenTransformerConvention(new SlugifyParameterTransformer()));
});
3.5 对于Asp.Net Core>=3.0 Razor Pages:
在StartUp中ConfiregeServices这样配置
services.AddRazorPages(options =>
{
options.Conventions.Add(new PageRouteTransformerConvention(new SlugifyParameterTransformer()));
});
这样会使/Sys/UserList路由变为/sys/user-list
3.6 对于上面MVC项目，路由模板要调整很多，其实还可以通过实现IControllerModelConvention来实现。
public class DashedRoutingConvention : IControllerModelConvention
{
public void Apply(ControllerModel controller)
{
var hasRouteAttributes = controller.Selectors.Any(selector =>
selector.AttributeRouteModel != null);
if (hasRouteAttributes)
{
// This controller manually defined some routes, so treat this
// as an override and not apply the convention here.
return;
}
foreach (var controllerAction in controller.Actions)
{
foreach (var selector in controllerAction.Selectors.Where(x => x.AttributeRouteModel == null))
{
var template = new StringBuilder();
if (controllerAction.Controller.ControllerName != "Home")
{
template.Append(PascalToKebabCase(controller.ControllerName));
}
if (controllerAction.ActionName != "Index")
{
template.Append("/" + PascalToKebabCase(controllerAction.ActionName));
}
selector.AttributeRouteModel = new AttributeRouteModel()
{
Template = template.ToString()
};
}
}
}
public static string PascalToKebabCase(string value)
{
if (string.IsNullOrEmpty(value))
return value;
return Regex.Replace(
value,
"(?
在StartUp中ConfiregeServices这样配置
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc(options => options.Conventions.Add(new DashedRoutingConvention()));
}
