Chapter 1 Web framework and implementation

 

Section 1 luci framework

OpenWRT web adopts the luci framework, which adopts the MVC design mode. The luci directory contains three important directories: controller, model, and view. Place the front-end htm file under view, the logical control file under controller, and some templates mapped to generate htm under model.

 

Controller Directory: organizes all the "logical processing" used by registering "Tree nodes. That is to say, all logical processing is organized like the branches and leaves of a tree.

Model: Business processing and htm production templates.

View: htm file.

Section 2 Write a file (*. lua) under the controller

As described in section 1, the controller acts as a logical organization in the luci framework. The encoding is divided into two parts:

1 "branch registration" --- module Registration

2 "leaf registration" --- node Registration

Module 1 Registration

For example, module ("luci. controller. admin. system", package. seeall)

Description: registers a system module under luci/controller/admin /.

 

2-node Registration

Row 1: function index ()

Row 2: entry ({"admin", "system", "system"}, cbi ("admin_system/system"), _ ("System"), 1)

Row 3: end

 

Rows 1 and 3 represent a function block.

Row 2: Indicates registering a system node under the admin/system module. The node sequence is 1 and cbi (discussed later)

Note: The fourth parameter sequence in Row 2 is very important. It will affect the display sequence on the web.

Entry () function analysis:

Parameter 1: The name of the inserted node, for example, {"admin", "system", "heyg1"}, indicates that the node heyg1 is inserted in the system of admin.

Parameter 2: The following methods are usually used to insert the heyg1 node:

Method 1: template Method. When this node is called, the corresponding htm file under view is directly called.

Method 2: The cbi/form method calls the corresponding files under the model for corresponding processing.

Method 3: call method, which calls the function of this file or the imported File

Other methods:

Alias: Indicates link to another node.

Here, the template ("heyg/heyg1") will call the view/heyg/heyg1.htm File

Parameter 3: The name of the inserted node at the corresponding position. The name is displayed in the corresponding menu on the web interface.

Here _ ("heyg1") is displayed as heyg1 in the web menu

Parameter 4: insert different types of nodes of the same level, or distinguish the numerical codes of other nodes of the same level.

Here, 3 cannot be the same as other options at the same level.

In the intermediate menu, the display is from small to large, such as: system (1), Administration (2), heyg1 (3 )....

 

Some attribute parsing of the Entry () function: for inserting a node, this node has some attributes in addition to the corresponding name and processing action, we can manually set its property value similar to entry (). dependent = false

The following attributes are provided on the official website:

Dependent: when the parent node of the node is lost, the node is protected so that it is not accidentally called.

Leaf: if there are other sub-nodes under the node, the sub-nodes will not continue to be parsed when the node is resolved to the end point.

Sysauth: A system account is required for verification when you use this node.

I18n: defines which files will be automatically loaded when a page request is requested.

Other attributes (purely self-guessed. If any error occurs, please do not spray them ):

Index: this node is used as the home page or the first page by default under the same level directory.
