hello dear.
this problem solved when i access project in localhost by add some configuration like this.
Configure<AbpDistributedCacheOptions>(options =>
{
options.GlobalCacheEntryOptions = new DistributedCacheEntryOptions()
{
//AbsoluteExpiration = DateTimeOffset.UtcNow.AddSeconds(60),
SlidingExpiration = TimeSpan.FromSeconds(60)//20 mins default
};
});
but when i access project from external api permissions does not updated without restarting bool why ?

Hi,
You can configure the
ApplicationConfigurationDtoCacheAbsoluteExpiration: https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.AspNetCore.Mvc.Client/Volo/Abp/AspNetCore/Mvc/Client/AbpAspNetCoreMvcClientCacheOptions.csBut it was added in version
7.1, if you don't want to upgrade your project version. you need to replace theMvcCachedApplicationConfigurationClientservice:[ExposeServices(typeof(ICachedApplicationConfigurationClient))] public class MyMvcCachedApplicationConfigurationClient : ICachedApplicationConfigurationClient, ITransientDependency { protected IHttpContextAccessor HttpContextAccessor { get; } protected AbpApplicationConfigurationClientProxy ApplicationConfigurationAppService { get; } protected ICurrentUser CurrentUser { get; } protected IDistributedCache<ApplicationConfigurationDto> Cache { get; } public MyMvcCachedApplicationConfigurationClient( IDistributedCache<ApplicationConfigurationDto> cache, AbpApplicationConfigurationClientProxy applicationConfigurationAppService, ICurrentUser currentUser, IHttpContextAccessor httpContextAccessor) { ApplicationConfigurationAppService = applicationConfigurationAppService; CurrentUser = currentUser; HttpContextAccessor = httpContextAccessor; Cache = cache; } public async Task<ApplicationConfigurationDto> GetAsync() { var cacheKey = CreateCacheKey(); var httpContext = HttpContextAccessor?.HttpContext; if (httpContext != null && httpContext.Items[cacheKey] is ApplicationConfigurationDto configuration) { return configuration; } configuration = await Cache.GetOrAddAsync( cacheKey, async () => await ApplicationConfigurationAppService.GetAsync(), () => new DistributedCacheEntryOptions { AbsoluteExpirationRelativeToNow = TimeSpan.FromSeconds(20) // the cache time } ); if (httpContext != null) { httpContext.Items[cacheKey] = configuration; } return configuration; } public ApplicationConfigurationDto Get() { var cacheKey = CreateCacheKey(); var httpContext = HttpContextAccessor?.HttpContext; if (httpContext != null && httpContext.Items[cacheKey] is ApplicationConfigurationDto configuration) { return configuration; } return AsyncHelper.RunSync(GetAsync); } protected virtual string CreateCacheKey() { return MvcCachedApplicationConfigurationClientHelper.CreateCacheKey(CurrentUser); } } -

how can i use this class to refresh permission cache
-

When the cache expires, it will get the latest permissions from the remote.

Hi,
For the
Tieredsolution:The MVC application loads the application configuration(permissions, settings... etc from remote(HttpApi.Host) and store it in the Redis cache. by default, the cache time is 5 mins.
That's why let you use this class because it changes the cache time to 20s(you can use any time span you want.)
Maybe I misunderstood something, please let me know.

hi i change AbsoluteExpirationRelativeToNow to 60 seconds (AbsoluteExpirationRelativeToNow = TimeSpan.FromSeconds(60)) it's works fine ,but i want to know if this configuration affect the performance of project ? and AbsoluteExpirationRelativeToNow refresh cache every 60 seconds or when i update permission it takes 60 seconds for the web to refresh ???

but i want to know if this configuration affect the performance of project
Yes, it may have some effect
and AbsoluteExpirationRelativeToNow refresh cache every 60 seconds or when i update permission it takes 60 seconds for the web to refresh
Yes, refresh every 60 seconds.
If you care about performance and want to refresh the web permission immediately, You can consider manually deleting the cache using Redis API.
In the HttpApi.Host project
public class MvcCurrentApplicationConfigurationCacheResetEventHandler : ILocalEventHandler<CurrentApplicationConfigurationCacheResetEventData>, ITransientDependency { protected IConfiguration Configuration { get; } public MvcCurrentApplicationConfigurationCacheResetEventHandler(IConfiguration configuration) { Configuration = configuration; } public virtual async Task HandleEventAsync(CurrentApplicationConfigurationCacheResetEventData eventData) { var redis = await ConnectionMultiplexer.ConnectAsync(Configuration["Redis:Configuration"]!); redis.GetDatabase().KeyDeleteAsync(...) // remove all application configuration caches. } }- In this way, you don't need to replace the
MvcCachedApplicationConfigurationClient

Hi could you tell me how can i manually deleting the cache (Permission cache ) in HandleEventAsync method ??

Hi,
For example:
var redis = await ConnectionMultiplexer.ConnectAsync(Configuration["Redis:Configuration"]!); foreach (var endPoint in redis.GetEndPoints()) { var keys = redis.GetServer(endPoint).Keys(pattern: "*ApplicationConfiguration*").ToArray(); await redis.GetDatabase().KeyDeleteAsync(keys.ToArray()); }
