Activities of "hiltond"

Hello,

I am working on developing with the ABP Studio microservice template and have a few questions on expected setup for new microservices. I have generated a basic setup using the microservice template (EF Core, MVC, no mobile UI). I follow the add new microservice (EF Core) option here: I get this initial layout:

It doesn’t seem like these microservice templates have proxy support by default (C# or JS). I would like to add this functionality in but have been struggling with how it should be added and what is required for full functionality.

I suspect that we would want to add some dependencies or setup code to the MyServiceModule and MyServiceContractsModule that mimics the HttpApi and HttpApi.Client from the DDD services in the past. I couldn’t glean any information from the other services because they seem to rely on full DDD components through library references.

I was able to generate a static JS proxy but could not understand the correct auth flow it required to work against an authorized endpoint. I could not get the C# proxies to properly generate at all (static or dynamic.)

A few things I would like clarified:

-          What is the minimum implementation to enable proxies (C#, JS, static and dynamic) in the new microservice service template? (I would like to avoid using more project layers than what already exists, this defeats the purpose of using the simpler service template) -          What is required for the Web project to use both the C# proxy through MVC razor and the JS proxy through a web page directly? -          Is anything required for the gateway? -          What is required for proper auth flows using both proxies?

Thanks!

• ABP Framework version: v8.1.1
• UI Type: MVC
• Database System: EF Core (SQL Server)
• Tiered (for MVC) or Auth Server Separated (for Angular): Studio Microservice Template

I have an existing module project that I have built to be a remote service. I am creating a web application project to be the main site. The setup I am going for is the web project has the web application and Identity Server setup, and the module project acts as a remote API that the web project accesses.

My module is in a separate solution and runs via a host project (the one that is generated by the CLI tool). I have removed Identity Server from this solution and would like the module to rely on the Identity Server host in my web project solution. The module handles its own migrations through the host project and has a separate DB from the web project.

For some reason I am struggling to get the dynamic C# client for the module to work in the web project across an authorized API call. I have no problems using it with unauthorized API endpoints. It is giving me a 401 unauthorized response when I attempt to access authorized endpoints. Below I have detailed the setup from a blank project of my web application in hopes of finding where I am going wrong.

Below is my process to create this issue:

1. Using ABP Suite 2.6.2, I generated a new solution using MVC, no mobile, EF Core, and non-tiered.
2. I ran the DbMigrator project to populate and setup the database. Runs successfully and I can confirm the database is populated.
3. Added a reference for RemoteServices in the web project appsettings.json to point at my module project.

  "RemoteServices": {
    "Devices": {
      "BaseUrl": "https://localhost:44375"
    }
  },

4. Added references in the dependencies of the web project for the module dlls for:
   • Application.Contracts
   • Domain.Shared
   • HttpApi.Client
5. Added a test page for accessing the remote API. I’m attempting to pull a single device with the identifier “string” from the remote API and displaying it on the page. The remote endpoint has an [Authorized] tag on it. If I remove the [Authorized] tag the call works, and I see the information on the page. If I have the tag it throws a 401 status response and doesn’t display the page.

Devices.cshtml

@page
@model NowMicro.Dice.Portal.Web.Pages.DevicesModel

<h2>Device Test</h2>
@{ var device = Model.Device; }
<p>Serial Number: </p>
@device.SerialNumber;

DevicesModel.cs

using Microsoft.AspNetCore.Authorization;
using NowMicro.Dice.Devices.Authorization;
using NowMicro.Dice.Devices.DtoModels;
using NowMicro.Dice.Devices.ServiceInterfaces;
using System.Threading.Tasks;
using Volo.Abp.AspNetCore.Mvc.UI.RazorPages;

namespace NowMicro.Dice.Portal.Web.Pages
{
    public class DevicesModel : AbpPageModel
    {
        public DeviceDto Device { get; set; }

        private readonly IDevicesAppService _devicesAppService;
        private readonly IAuthorizationService _authorization;

        public DevicesModel(IDevicesAppService devicesAppService, IAuthorizationService authorization)
        {
            _devicesAppService = devicesAppService;
            _authorization = authorization;
        }

        public async Task OnGetAsync()
        {
            if (!await _authorization.IsGrantedAsync(DevicesPermissions.Devices.Default))
            {
                Redirect("/");
            }
            Device = await _devicesAppService.GetAsync("string");
        }
    }
}

6. In the WebModule.cs file in the web project I added an addition to the DependsOn tag at the top for: typeof(DevicesHttpApiClientModule) which is the HttpApiClient module for the remote API module.
7. Added a nuget reference to Volo.Abp.Http.Client in the web project to fix this error:

[FTL] Host terminated unexpectedly!
System.IO.FileNotFoundException: Could not load file or assembly 'Volo.Abp.Http.Client, Version=2.6.2.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

8. I run the project and in Identity Management > Users I give the admin user permissions to the remote API permission set.
9. In the Identity Server > Api Resources section I created a new resource for the remote API.
   • Name: Devices
   • Display Name: Devices API
   • Owned Claims: sub, name, email, role
10. In the module appsettings.json I make sure the Authority url is that of the web project.
11. I attempt to go to the devices page while both module and web projects are running and I get an unauthorized result as found in the web project logs:

I’ve had no luck in figuring out why I continue to get unauthorized results. Any help in deciphering this is much appreciated. Let me know if you need any more information from me.
