ASP.NET Core默认使用像http://localhost:5000/DashboardSettings/Index这样的CamelCase-Routes。但我想使用由破折号分隔的小写路由:http://localhost:5000/dashboard-settings/index它们更常见且更一致,因为我的应用程序扩展了一个运行Wordpress的网站,该网站还有带破折号的小写网址。
我了解到我可以使用路由选项将网址更改为小写:
services.ConfigureRouting(setupAction => {
setupAction.LowercaseUrls = true;
});
这有效,但给了我的网址没有任何像http://localhost:5000/dashboardsettings/index这样的分隔符,这些分隔符很难读。我可以使用路径属性来定义自定义路由,如
[Route("dashboard-settings")]
class DashboardSettings:Controller {
public IActionResult Index() {
// ...
}
}
但这会导致额外工作并且容易出错。我更喜欢一个自动解决方案,它搜索大写字符,在它们之前插入一个破折号并使大写字母小写。对于旧的ASP.NET来说,这不是一个大问题,但在ASP.NET Core上,我看不到如何处理这个问题的方向。
这是怎么做到这里的?我需要某种接口,我可以生成url(比如标记帮助器),并用dash-delimiters替换CamelCase。然后我需要另一种接口用于路由,以便将破折号分隔符URL转换回CamelCase,以便与我的控制器/动作名称正确匹配。

派对有点晚了但是.. 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,
"(?<!^)([A-Z][a-z]|(?<=[a-z])[A-Z])",
"-$1",
RegexOptions.Compiled)
.Trim()
.ToLower();
}
}
然后在Startup.cs中注册
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc(options => options.Conventions.Add(new DashedRoutingConvention()));
}

我正在使用Asp.NetCore 2.0.0和Razor Pages(不需要显式控制器),所以只需要:
启用小写网址:
services.AddRouting(options => options.LowercaseUrls = true);
创建名为Dashboard-Settings.cshtml
的文件,生成的路由变为/dashboard-settings

在ConfigureServices
类的Startup
方法中:
services.AddRouting(option =>
{
option.ConstraintMap["slugify"] = typeof(SlugifyParameterTransformer);
option.LowercaseUrls = true;
});
SlugifyParameterTransformer
类应如下所示:
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();
}
}
并且路由配置应如下:
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller:slugify}/{action:slugify}/{id?}",
defaults: new { controller = "Home", action = "Index" });
});
这将使/Employee/EmployeeDetails/1
到达/employee/employee-details/1

从ASP.NET Core 2.2 documentation复制:
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc(options =>
{
options.Conventions.Add(new RouteTokenTransformerConvention(
new SlugifyParameterTransformer()));
});
}
public class SlugifyParameterTransformer : IOutboundParameterTransformer
{
public string TransformOutbound(object value)
{
if (value == null) { return null; }
// Slugify value
return Regex.Replace(value.ToString(), "([a-z])([A-Z])", "$1-$2").ToLower();
}
}

感谢您提供相关信息,但是最好过滤选择器,以便跳过那些使用自定义路由模板的信息:例如[HttpGet("/[controller]/{id}")]
foreach (var selector in controllerAction.Selectors
.Where(x => x.AttributeRouteModel == null))
