Proxify

Simple, Fast and reliable Dynamic Proxy for ASP.NET Core 2.0 and later

Getting Started

Use these instructions to get the package and use it.

Install

From the command prompt

dotnet add package Mohmd.AspNetCore.Proxify

or

Install-Package Mohmd.AspNetCore.Proxify

or

paket add Mohmd.AspNetCore.Proxify

Configure

Add service

public void ConfigureServices(IServiceCollection services)
{
  services.AddProxify()
      // add every assembly that might contains interceptors
      .AddAssemblyByType<Startup>()
      .Build()
      // then add services to IoC
      .AddScopedProxyService<ISampleService, SampleService>();

  // you can add services separately.
  services.AddTransientProxyService<ISample2Service, Sample2Service>();
}

Create interceptors this way:

public class ProfilingInsterceptor : IInterceptor
{
    private Stopwatch _stopwatch = new Stopwatch();
    private readonly ILogger _logger;

    public ProfilingInsterceptor(ILogger<ProfilingInsterceptor> logger)
    {
        _logger = logger;
    }

    // we can prioritize interceptors
    public int Priority => 2;

    public async Task Intercept(IInvocation invocation)
    {
        try
        {
            // add codes to run before invoking the target method
            _stopwatch.Start();

            // run next interceptor or invoke the target method
            await invocation.Proceed();

            // if we reach here, it means invoking the target method
            // is finished, now if the target method had a return value
            // we can access it
            var returnValue = invocation.ReturnValue;
        }
        catch (Exception ex)
        {
            // add codes to run on exceptions
        }
        finally
        {
            // add codes to run after invoking the target method
            _stopwatch.Stop();
            _logger.LogInformation($"Invoking {invocation.Method.Name} took {_stopwatch.Elapsed.ToString()} = `{invocation.ReturnValue}`.");
        }
    }
}
