Big talk Domain Driven Design -- presentation layer and others

summary

The presentation layer is also called the user interface layer , Pages containing applications 、 Components etc. UI Elements .

The service layer provides HTTP API Interface , contain MVC Controller And related components .

ABP Although the framework provides many components in the presentation layer , But these and DDD It doesn't matter much in itself . And with the popularity of front-end and back-end separation architectures , We seldom use ABP Presentation layer functions provided , So this chapter , Do not give a detailed description of its usage .

This chapter , I will focus on the class libraries mentioned in the previous chapter ,ABP Other class libraries under the template, including the presentation layer, are divided and used .

overview

The presentation layer ：

Web： yes ABP One of the MVC project , If we don't separate the front and rear ends , Use this item as the presentation layer . Include all interfaces under the project .

HttpApi.Host： yes ABP One of the WebAPI project , It is used to separate the front and back end architectures WebAPI service . Contains pipe model configuration 、 Basic codes such as service settings , Does not include a user interface , It also does not include the Controller.‍

Service layer ：

HttpApi： This project contains custom Controller, If dynamic is not used WebAPI Instead, we want the controller to be written by ourselves , It needs to be written in the project .

Client agent ：

HttpApi.Client： Is a client dynamic proxy project , If our service is by another ABP Project call ,ABP The framework automatically generates the proxy function called by the client , The client only needs to reference this project , And make corresponding configuration , That is, you can quickly invoke services by relying on injection . In the last chapter 《ABP Detailed tutorial of microservice architecture 》 In the implementation of the aggregation service layer , We used this mechanism .

Conclusion

This series ends here , In this series , I am interested in the strategic and tactical design of Domain Driven Design and ABP The framework explains the usage of basic components for tactical design .

Back , I'm going to open another series as ABP Supplementary tutorials on various uses of the framework .
