This article mainly explains in detail the use of the replaced Autofac to implement AOP interception in ASP.NET Core.

Aspect Oriented Programming (AOP) is a hot topic. The main purpose of AOP is to extract the cut-to-face surface in the business processing process, which is faced with a certain step or stage in the processing process to obtain the isolation effect of low coupling between the parts of the logic process.

Introduce class libraries

The nuget command is as follows:


Autofac is used to implement AOP

First, we create an intercept class with the following code:

Here, you need to inherit the IInterceptor and then implement its Intercept method: We directly output the intercepted content to the debug window (official project: Please operate the interception according to the business):

Here I use ILogger to record the operation, as follows:

Find the services we want to intercept, TestService1 and TestService2, and we do it in two ways.

TestService1: Intercepted by a feature
TestService2: Intercept by configuration

The code is as follows:

In the Startup editing method ConfigureServices, block the TestService2 service by configuring it as follows:

The important code is as follows:

Note here that you must add it after the service you injectEnableInterfaceInterceptorsto turn on your interception

The controller code is as follows:

Start the project via the dotnet run command, access the URL, and the console output log is as follows:



We found that the return value intercepted by AOP is the same as that returned to the web page, so we have completed AOP interception with Autofac.

It is best to have the source code of the instance

The project contains sensitive information, so I won't send it, and the tutorial is already very detailed

Is there a framework for this to be implemented? The owner writes his own code? What else is a high-quality response...
