Asp.net Core 3.1- 我如何 return 从控制器到 Razor 页面？

Question

我希望当用户登录到该站点时，在剃须刀页面中转到我想要的地址...

  if (rolename == "User")
       {            
        return RedirectToPage("Dashboard","Profile");
       }

此代码无法正常工作...

错误信息如下：

InvalidOperationException: The relative page path 'Dashboard' can only be used while executing a Razor Page. Specify a root relative path with a leading '/' to generate a URL outside of a Razor Page. If you are using LinkGenerator then you must provide the current HttpContext to use relative pages.

如何做到这一点？

Answer 1

RedirectToPage 有多个不同参数的方法，您所做的与以下方法有关：

        //
    // Summary:
    //     Redirects (Microsoft.AspNetCore.Http.StatusCodes.Status302Found) to the specified
    //     pageName using the specified pageHandler.
    //
    // Parameters:
    //   pageName:
    //     The name of the page.
    //
    //   pageHandler:
    //     The page handler to redirect to.
    //
    // Returns:
    //     The Microsoft.AspNetCore.Mvc.RedirectToPageResult.
    [NonAction]
    public virtual RedirectToPageResult RedirectToPage(string pageName, string pageHandler);

在你的情况下，它应该是：

return RedirectToPage("/Profile/Dashboard");

此外，请务必添加剃刀页面路由：

 public void ConfigureServices(IServiceCollection services)
 {
     services.AddRazorPages(); 
 }

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
 {
        //...

     app.UseEndpoints(endpoints =>
     {               
         endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Privacy}/{phrase?}");

         endpoints.MapRazorPages();

     });          
 }
