更改ASP.NET Core RazorPages中cshtml文件的名称

加载应用程序时,框架会为您加载一组 PageRouteModel 从razor页面文件夹自动生成的。每个这样的模型都包含一组 SelectorModel AttributeRouteModel . 你需要做的就是修改它 AttributeRouteModel.Template

您可以创建一个自定义 IPageRouteModelConvention 针对每个 PageRouteModel AttributeRouteModel.Template ,它可能与其他现有路线重复)。除非您必须管理一组共享的管线模板。相反,您可以创建一个自定义 IPageRouteModelProvider . 它提供了所有 PageRouteModel Index.cshtml 和 Index.generated.cshtml 你想让它摘下来 . 如果生成的视图不存在,则默认为

下面是详细的代码:

public class SuffixedNamePageRouteModelProvider : IPageRouteModelProvider
{
    public SuffixedNamePageRouteModelProvider(string pageNameSuffix, int order = 0)
    {
        _pageNameSuffixPattern = string.IsNullOrEmpty(pageNameSuffix) ? "" : $"\\.{Regex.Escape(pageNameSuffix)}$";
        Order = order;
    }
    readonly string _pageNameSuffixPattern;
    public int Order { get; }

    public void OnProvidersExecuted(PageRouteModelProviderContext context)
    {

    }

    public void OnProvidersExecuting(PageRouteModelProviderContext context)
    {
        if(_pageNameSuffixPattern == "") return;
        var suffixedRoutes = context.RouteModels.Where(e => Regex.IsMatch(e.ViewEnginePath, _pageNameSuffixPattern)).ToList();
        var overriddenRoutes = new HashSet<string>(StringComparer.OrdinalIgnoreCase);
        foreach (var route in suffixedRoutes)
        {
            //NOTE: this is not required to help it pick the right page we want.
            //But it's necessary for other related code to work properly (e.g: link generation, ...)
            //we need to update the "page" route data as well
            route.RouteValues["page"] = Regex.Replace(route.RouteValues["page"], _pageNameSuffixPattern, "");

            var overriddenRoute = Regex.Replace(route.ViewEnginePath, _pageNameSuffixPattern, "");
            var isIndexRoute = overriddenRoute.EndsWith("/index", StringComparison.OrdinalIgnoreCase);

            foreach (var selector in route.Selectors.Where(e => e.AttributeRouteModel?.Template != null))
            {
                var template = Regex.Replace(selector.AttributeRouteModel.Template, _pageNameSuffixPattern, "");
                if (template != selector.AttributeRouteModel.Template)
                {
                    selector.AttributeRouteModel.Template = template;
                    overriddenRoutes.Add($"/{template.TrimStart('/')}");
                    selector.AttributeRouteModel.SuppressLinkGeneration = isIndexRoute;
                }                                                                              
            }
            //Add another selector for routing to the same page from another path.
            //Here we add the root path to select the index page
            if (isIndexRoute)
            {
                var defaultTemplate = Regex.Replace(overriddenRoute, "/index$", "", RegexOptions.IgnoreCase);
                route.Selectors.Add(new SelectorModel()
                {
                    AttributeRouteModel = new AttributeRouteModel() { Template = defaultTemplate }
                });
            }
        }
        //remove the overridden routes to avoid exception of duplicate routes
        foreach (var route in context.RouteModels.Where(e => overriddenRoutes.Contains(e.ViewEnginePath)).ToList())
        {
            context.RouteModels.Remove(route);
        }
    }
}

登记 IPageRouteModelProvider Startup.ConfigureServices :

services.AddSingleton<IPageRouteModelProvider>(new SuffixedNamePageRouteModelProvider("generated"));
