解决报错：Unable to resolve service for type 'AspNetCoreRateLimit.IProcessingStrategy' while attempting to activate 'AspNetCoreRateLimit.IpRateLimitMiddleware

Unable to resolve service for type 'AspNetCoreRateLimit.IProcessingStrategy' while attempting to activate 'AspNetCoreRateLimit.IpRateLimitMiddleware

4.x起，需在Startup.cs的ConfigureServices(IServiceCollection services)中注册：

services.AddSingleton<IProcessingStrategy, AsyncKeyLockProcessingStrategy>();
