Password flow deployment error #392

Esben_Dalgaard created 6 years ago

ABP Framework version: v3.0.5
UI type: Angular
DBType: EFC, modified for MySQL
Tiered (MVC) or Identity Server Seperated (Angular): no
Exception message and stack trace:

Steps to reproduce the issue:
Database with multiple join tables for DB business model
Frontend running on Microsoft Azure App service.
Backend Running on Microsoft Azure App service. Works when contacted by Postman.
CORS in enabled on App service for backend. Appsetting.json: Appsettings.Production.json: Environment.prod.ts:

The frontend is deployed by ng build --prod and uploaded by filezilla to the app services wwwroot folder. Before CORS was enabled on backend, a bearer token was recieved, but it had no effect and did not keep the user logged in.

How do we set up so that the backend and frontend can communicate properly?

Hi,

You can see that invalid_client. I think is your client's callback url has wrong.

Where would I change that? I.e., where is that cutout from?

Find IdentityServerDataSeedContributor in your project or change the IdentityServerClientRedirectUris table directly in the database

Added the code to the HttpApi.Host part of the solution and published to azure, but it had no effect. It still won't keep the user logged in.

using System;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;

namespace AdministrativeDBModel

    public static class SameSiteCookiesServiceCollectionExtensions

            services.Configure<CookiePolicyOptions>(options =>

                options.MinimumSameSitePolicy = Unspecified;
                options.OnAppendCookie = cookieContext =>
                CheckSameSite(cookieContext.Context, cookieContext.CookieOptions);
                options.OnDeleteCookie = cookieContext =>
                CheckSameSite(cookieContext.Context, cookieContext.CookieOptions);
            });

            return services;

I emailed you twice nad contacted abp directly (Sorry about that, I don't mean to be pushy, it's just business critical for us). Was the mail caught in spam?

But sadly no, it has not been resolved. We're also combatting some issues with the new update atm(as are you probably), so I haven't gotten around to see if it persists in this new version. I'll try sending the email again, and hopefully it'l work this time :)
