We work on a mircroservice applicaction.
I have a function on service 2 (for sending message) that can be use from UI (user can send message) or via backgroud job (every x mins check if I've message to send).
If I try to send message via UI my user is valid and I can pass the token from service 1 -> service 2 but when I try to run it on background job it doesn't work. So it works correctly because background is different process/thread so it don't have an authenticated context.
My question wich is the correct configuration for allow my service 1 work for users and jobs? Is it possibile or I need to move my job in a different service?

Hi,
You can change the current user context. For example:
public class MyBackgroundJob : AsyncBackgroundJob<MyBackgroundJobArgs> { private readonly ICurrentPrincipalAccessor _principalAccessor; private readonly IdentityUserManager _identityUserManager; public MyBackgroundJob(ICurrentPrincipalAccessor principalAccessor, IdentityUserManager identityUserManager) { _principalAccessor = principalAccessor; _identityUserManager = identityUserManager; } public override async Task ExecuteAsync(MyBackgroundJobArgs args) { // get messages.... var messages = ....; using (_principalAccessor.Change(await CreateUserClaimsPrincipalFromMessagesAsync(messages))) { //send messages here... } } private async Task<ClaimsPrincipal> CreateUserClaimsPrincipalFromMessagesAsync(messages...) { var user = await _identityUserManager.FindByNameAsync(messages.UserName); var roles = await _identityUserManager.GetRolesAsync(user); var claims = new List<Claim> { new Claim(AbpClaimTypes.UserId, user.Id.ToString()), new Claim(AbpClaimTypes.UserName, user.UserName), new Claim(AbpClaimTypes.Email,user.Email), new Claim(AbpClaimTypes.TenantId,user.TenantId?.ToString()), }; claims.AddRange(roles.Select(x => new Claim(AbpClaimTypes.Role, x))); return new ClaimsPrincipal(new ClaimsIdentity(claims)); } } -

Hi
great suggestion to solve this case.
But generally speaking which is the best practice to execute operation via backgroud job in a microservice env?
In my case my service has complete different db so it doesn't access to abpUser / abpRole table
