Problems solved by technology

[0004] However, the inventor found that the existing data extraction method has at least the following problems: the data extraction method in the traditional technology needs to grab the network data by the control layer object, and then encapsulate the network data according to the data carrier object defined by the model layer, so that the control layer The coupling degree between the layer and the model layer increases, that is, when the class attribute item of the data carrier object needs to be modified, the code of the control layer needs to be modified accordingly, thereby reducing the scalability

Embodiment Construction

[0024] The full name of MVC is Model-View-Controller, which is the abbreviation of model (model), view (view), and controller (controller). It is a software design paradigm for organizing code and using a software that separates business logic and data display. Architecture, the premise of this approach is that if the business logic is gathered into a component, and the interface and user interaction around the data can be improved and customized without rewriting the business logic, MVC is uniquely developed to map the traditional The input, processing and output functions are organized in a logical graphical user interface.

[0025] like figure 1 As shown, the view layer object is used to define the display mode and style of data, the model layer object is used for persistent storage of data, and the control layer object is used to extract data from the model layer object according to the preset reading business logic, and It is sent to the view layer object for expression,...

Abstract

Systems and methods are provided for data extraction based on model- view- controller (MVC). For example, a data extraction request of a control layer object is acquired; network address parameters and a data carrier object corresponding to the data extraction request are acquired; a network data capturing function of the data carrier object is called based on at least information associated with the network address parameters to capture network data; the captured network data is analyzed based on at least information associated with the data carrier object; value assignment is performed on the data carrier object based on at least information associated with the analysis of the network data; and the data carrier object is returned to the control layer object corresponding to the data extraction request.

Description

technical field [0001] The invention relates to the field of computing technology, in particular to an MVC-based data extraction method and device. Background technique [0002] In the traditional MVC (Model-View-Controller, Model-View-Controller pattern) design paradigm, the data flow is controlled by the control layer object, and the control layer object can extract data from the model layer object and send it to the view layer object for processing. It can also receive the input data obtained by the view layer object and store it in the model layer object. [0003] Moreover, the control layer object usually needs to capture network data according to business requirements, and then encapsulate the captured network data into a data carrier object at the control layer, and then send the data carrier object to the view layer for display, and the Data carrier objects are stored into the model layer. [0004] However, the inventor found that the existing data extraction metho...
