An Abp module helps you control how often your service is used.

1. Install the following NuGet packages. (see how)

   • EasyAbp.Abp.AspNetCoreRateLimit.AspNetCoreRateLimit
   • EasyAbp.Abp.AspNetCoreRateLimit.AspNetCoreRateLimit.Client
   • EasyAbp.Abp.AspNetCoreRateLimit.AspNetCoreRateLimit.Ip

2. Add DependsOn(typeof(AbpClientLimiterModule)) and DependsOn(typeof(AbpIpLimiterModule)) attribute to configure the module dependencies. (see how)

3. Extends IHostBuilder with Limiter configuration methods.

   IHostBuilder.UseAspNetCoreRateLimitIp();
   IHostBuilder.UseAspNetCoreRateLimitClient();

4. Register the middleware below within the OnApplicationInitialization() method of AppModule.cs "before" the UseRouting() middleware:

   app.UseIpRateLimiting();
   app.UseClientRateLimiting();

5. Add the following code at ConfigureServices() method

   context.Services.AddLimiterService<MemoryCacheRateLimitCounterStore>(service =>
   {
       service.AddLimiterIpService<MemoryCacheIpPolicyStore>();
       service.AddLimiterClientService<MemoryCacheClientPolicyStore>();
   });

Rate limiting based on client ID

• Setup and configuration
• Defining rate limit rules
