View

   .Pdf(p => {
       p.ExportUrl(Url.Action("Export"));
   })
   .Fonts(f =>
   //...
)

Controller

public IActionResult Export(string base64, string fileName) {
    byte[] fileContents = System.Convert.FromBase64String(base64);
    return Ok();
}

Note

If you apply the [ApiController] attribute to your controller, you should add the [FromForm] attribute to parameters in the Export action.

C#

public IActionResult Export([FromForm]string base64, [FromForm]string fileName) {
   byte[] fileContents = System.Convert.FromBase64String(base64);
   return Ok();
}

For Razor Pages web apps only

To use the ExportUrl method in a Razor Pages web app, it is necessary to add the following adjustments.

Disable the AntiForgeryToken option (enabled for Razor Pages web apps by default).

• To disable the AntiForgeryToken for an application, add the following code in the Program.cs file:

  builder.Services.AddMvc().AddRazorPagesOptions(o => {
      o.Conventions.ConfigureFilter(new Microsoft.AspNetCore.Mvc.IgnoreAntiforgeryTokenAttribute());
  });
  

• To disable the AntiForgeryToken for a page, add the following code to a page model.

  [IgnoreAntiforgeryToken]
  public class IndexModel : PageModel {
      public void OnPost() {
      }
  }    
  

Declare a POST action handler to save a document.

C#

 public void OnPostExport(string base64, string fileName) {
    byte[] fileContents = System.Convert.FromBase64String(base64);
 }

Use this handler in the ExportUrl method as follows.

C#

    .ExportUrl("RichEditPage?handler=export")
