create callback url in asp.net core api-CodePudding

I try to use Identity in asp.net core API, everything works fine except I couldn't find a way to create call back url for email confirmation. I searched a lot, but no one implemented Identity with email confirmation in ASP.NET core API.

Here's my RegisterUser code:

var user = new ApplicationUser
        {
            Name = model.Name,
            Email = model.Email,
            UserName = model.Email
        };

var result = await _userManager.CreateAsync(user, model.Password);

if (result.Succeeded)
{
    await _userManager.AddToRoleAsync(user, "User");

    var token = await _userManager.GenerateEmailConfirmationTokenAsync(user);
    var callbackurl = Url.RouteUrl("ConfirmEmail", new { userId = user.Id, token = token }, protocol: Request.Scheme);
    var message = new Message(
              new string[] { model.Email },
              Messages.Email_Confirmation,
               Messages.Email_CreateUser_Body   "<a href=\""   callbackurl   "\">link</a>"
            );

    _emailSender.SendEmail(message);

    return Ok();
}

The above code 'callbackurl' return null. I tried other methods for creating url but it won't work.

Thanks in advance for your help

CodePudding user response：

I found the root cause, it is because you are missing routing configuration.

In .net6, program.cs

...
app.MapControllers();

// add this code
app.MapControllerRoute(
    name: "ConfirmEmail",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

This is just my test code, I reproduce the issue in my local, and I faced the issue, and after add app.MapControllerRoute, it works.
