Hi,

I'm assuming you have created the Account folder in the Pages folder of the MyProjectName.IdentityServer project :)

CustomLoginModel.cs in Account folder

    [Dependency(ReplaceServices = true)]
    [ExposeServices(typeof(LoginModel))]
    public class CustomLoginModel : LoginModel
    {
        public CustomLoginModel(
            IAuthenticationSchemeProvider schemeProvider, 
            IOptions<AbpAccountOptions> accountOptions, 
            IAbpRecaptchaValidatorFactory recaptchaValidatorFactory, 
            IAccountExternalProviderAppService accountExternalProviderAppService, 
            ICurrentPrincipalAccessor currentPrincipalAccessor, 
            IOptions<IdentityOptions> identityOptions, 
            IOptionsSnapshot<reCAPTCHAOptions> reCaptchaOptions) : 
            base(schemeProvider, 
                accountOptions, 
                recaptchaValidatorFactory, 
                accountExternalProviderAppService, 
                currentPrincipalAccessor, 
                identityOptions, 
                reCaptchaOptions)
        {
            Console.WriteLine("Test QA Question");
        }
    }

Please let us know if it works after you try it.

CustomLoginModel.cshtml in Account folder

        } 
    }

Please let us know if it works after you try it.

I'm a little confused by your response as you mentioned that this should be done in the cshtml file not the class. Could you list exactly what I need to do in order to do this as I've seend some conflicting information in the documentation.

Thanks

To be more specific I want to override the look of of the login page, meaning I don't want the tennant selector and I also want to add/remove items in the login box and do custom code (calling different services) behind the various button clicks.

First of all it will be CustomLoginModel.cs not CustomLoginModel.cshtml :(

So it's my fault that you're confused, I hope I can make up for it :)

If we have to go step by step 👇

Create a new Login.cshtml under Pages\Account folder

Login.cshtml

@page
@using Microsoft.AspNetCore.Mvc.Localization
@using Microsoft.Extensions.Options
@using Owl.reCAPTCHA
@using Volo.Abp.Account.Localization
@using Volo.Abp.Account.Public.Web.Security.Recaptcha
@using Volo.Abp.Account.Settings
@using Volo.Abp.Settings
@model Volo.Abp.Account.Public.Web.Pages.Account.LoginModel
@inject IHtmlLocalizer<AccountResource> L
@inject Volo.Abp.AspNetCore.Mvc.UI.Layout.IPageLayout PageLayout
@inject ISettingProvider SettingProvider
@{
    PageLayout.Content.Title = L["Login"].Value;
    var reCaptchaVersion = await SettingProvider.GetAsync<int>(AccountSettingNames.Captcha.Version);
    if (Model.UseCaptcha)
    {
        await Model.ReCaptchaOptions.SetAsync(reCaptchaVersion == 3 ? reCAPTCHAConsts.V3 :reCAPTCHAConsts.V2);
    }

}

@section scripts
{
    <abp-script src="/Pages/Account/Login.js" />
    @if (Model.UseCaptcha)
    {
        if (reCaptchaVersion == 3)
        {
            <recaptcha-script-v3/>
            <recaptcha-script-v3-js action="login" callback="(function(){$('#@RecaptchaValidatorBase.RecaptchaResponseKey').val(token)})"/>
        }
        else
        {
            <recaptcha-script-v2/>
        }
    }
}

@section styles

Create CustomLoginModel.cs file in the same folder (Pages\Account) CustomLoginModel.cs

using System;
using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Identity;
using Microsoft.Extensions.Options;
using Owl.reCAPTCHA;
using Volo.Abp.Account.ExternalProviders;
using Volo.Abp.Account.Public.Web;
using Volo.Abp.Account.Public.Web.Pages.Account;
using Volo.Abp.Account.Security.Recaptcha;
using Volo.Abp.DependencyInjection;
using Volo.Abp.Security.Claims;

namespace TestQABZ.Pages.Account
{
    [Dependency(ReplaceServices = true)]
    [ExposeServices(typeof(LoginModel))]
    public class CustomLoginModel : LoginModel
    {
        public CustomLoginModel(
            IAuthenticationSchemeProvider schemeProvider, 
            IOptions<AbpAccountOptions> accountOptions, 
            IAbpRecaptchaValidatorFactory recaptchaValidatorFactory, 
            IAccountExternalProviderAppService accountExternalProviderAppService, 
            ICurrentPrincipalAccessor currentPrincipalAccessor, 
            IOptions<IdentityOptions> identityOptions, 
            IOptionsSnapshot<reCAPTCHAOptions> reCaptchaOptions) : 
            base(schemeProvider, 
                accountOptions, 
                recaptchaValidatorFactory, 
                accountExternalProviderAppService, 
                currentPrincipalAccessor, 
                identityOptions, 
                reCaptchaOptions)
        {
            Console.WriteLine("Test QA");
        }
    }
}

Add a CSS to play with the existing styles. Create Login.css in the same folder (Pages\Account) Login.css

.container {
    background-color: #d0d08c;
}

.card {
    background: #bccce4;
}

Add a JS to write JavaScript. Create Login.js in the same folder (Pages\Account) Login.js

alert('login page loaded.');

When we do all these, you will have a structure similar to the one below:

Once it's up and running, you can make any changes you want, but if you encounter a problem, please let us know again.

Hi,

I've tried what you suggest and still continue to get an error as shown below.

Spospisil created 3 years ago

Keep in mind I'm trying to override the login page at the 'public' web application level, not Identity Server.

Hi,

In our previous conversations, you did not say that you want to do it on the public web side.

As a solution: Compare the MyProjectNameWebPublicModule in the MyProjectName.Web.Public project with the MyProjectNameIdentityServerModule in the MyProjectName.IdentityServer project and add the missing ones to the MyProjectNameWebPublicModule. As a result, you will reach the view in the image below.

Please let us know if it works after you try it.

Hi,

That resolved what I was trying to accomplish, but I'm still getting other errors. Do you have an working example of a public web site where I can completely override not only the UI aspect of the login page but also put additional logic in the OnPostAsync methed of the login page to do additional processing after the base Volo.Abp.Account.Public.Web.Pages.Account.LoginModel OnPostAsync method runs?

The Volo.EasyCrm real world application does not implement the login page in this same way.

Steve.

Hi,

To do this, you need to override the OnPostAsync method;

        // For example
        public override async Task<IActionResult> OnPostAsync(string action)
        {
            Console.WriteLine("OnPost - Before");
            var result = await base.OnPostAsync(action);
            Console.WriteLine("OnPost - After");

            return result;
        }

Then remove the following two lines from the ConfigureAuthentication method in MyProjectNamePublicWebModule.

    options.DefaultScheme = "Cookies";
    options.DefaultChallengeScheme = "oidc";

The final state should be as in the picture;

Finally, add the following code to the appsettings.json file of the MyProjectName.Web.Public project:

  "ConnectionStrings": {
    "Default": "MY-CONNECTION-STRING"
  }

You can try to run the application and login to the public web side.

Note: If you encounter a problem like the picture below after logging in, remove the relevant places from MyProjectNamePublicMenuContributor.

As a result, you can now login via the Public web application and customize it as you wish.

Ok, I was finally able to get this to work. My question now is how can I interrogate whether or not the user was successfully authenticated after the .base.OnPostAsync(action) result is returned. I don't see an obvious way to determine this.

// For example public override async Task<IActionResult> OnPostAsync(string action) { Console.WriteLine("OnPost - Before"); var result = await base.OnPostAsync(action); Console.WriteLine("OnPost - After");

        return result;
    }

Disregard. It looks like I'm having an issue with identity server and the 'CurrentUser.IsAuthenticated' property is never being set to true.

Actually, I faced the same problem, and deleting the following two lines that I said in my previous answer solved my problem.

Then remove the following two lines from the ConfigureAuthentication method in MyProjectNamePublicWebModule.

    options.DefaultScheme = "Cookies";
    options.DefaultChallengeScheme = "oidc";

I think you can search other places where this is used and delete and test the ones you find one by one.

However, since this issue has been resolved, I'm closing this here.
