Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1 and 2, an XML parsing module based on XML rules includes the following sub-modules:
database model class submodule: the method comprises the steps of creating an sqilite database according to an XML configuration file, generating a database table contained in the database, and establishing a mapping relation between a database model class and the database table;
the XML configuration file is exemplified by the following:
< Network desc= "Network Settings" > parent node start
< id type= "int" range= "1..5"/> child node number, range 1-5
< interface type= "enum" range= "lan0 lan1 lan2 lan3 lan4" default= "lan0" unique= "true"/> child node interface type, range lan0 lan1 lan2 lan3 lan4, default lan0, unique means non-repeatable configuration, e.g. cannot have both child nodes configured as lan0
< IP type= "ip_addr" default= "192.168.0.1" desc= "IP Address"/> -child node IP Address
< netmask type= "ip_addr" default= "255.255.255.0"/> "child node subnet mask
< mtu type= "int" range= "68..1500" default= "1500" > mtu configuration of child node, range 68-1500
Ending of parent node of network
The configuration file specifies the sequence number of the child node, the interface type, the IP address, the subnet mask, mtu configuration.
The database model class corresponds to a table in the database that defines, for example, which fields are included, but does not include specific data, i.e., the table is empty if there are no objects.
The class object corresponds to a record of the table in the database, and there are 10 data records for 10 objects.
The XML configuration file automatically generates class objects as follows:
class name definition of database
INTERFACE_TYPE_1＝'lan0'
INTERFACE_TYPE_2＝'lan1'
INTERFACE_TYPE_3＝'lan2'
INTERFACE_TYPE_4＝'lan3'
INTERFACE_TYPE_5= 'lan4' lan0-lan5 is an enumeration item, which will be used below
INTERFACE_TYPE_ITEM＝[
(0,INTERFACE_TYPE_1),
(1,INTERFACE_TYPE_2),
(2,INTERFACE_TYPE_3),
(3,INTERFACE_TYPE_4),
(4,INTERFACE_TYPE_5),
Interface type definition, using the enumeration type defined above, indicates that the configuration item can only select items in the enumeration type, otherwise, it is illegal.
id＝models.IntegerField(primary_key＝True,unique＝True,auto_created＝True)
Entry ID field, primary key of database, automatic generation (without user setting), and unrepeatable
interface＝models.IntegerField(choices＝INTERFACE_TYPE_ITEM,default＝0)
The INTERFACE TYPE field can only select the enumeration TYPE defined above, otherwise illegally, default to INTERFACE_TYPE_1, i.e. lan0
ip＝models.IPAddressField(default＝'192.168.0.1')
The IP address field, default to 192.168.0.1
netmask＝models.IPAddressField(default＝'255.255.255.0')
The subnet mask field defaults to 255.255.255.255.0
mtu＝models.IntegerField(default＝1500)
Mtu field, default 1500
The parent node of the XML corresponds to a class name, each child node of the XML corresponds to a field, and the enum attribute in the XML corresponds to an enumerated item in the database.
After the class object is generated, executing corresponding commands in the django framework, wherein the commands are two commands of a message.
The configuration parameters of different pages belong to different database tables, namely different XML files are to be built. For example, if a new APP is to be added, the app.xml needs to be newly created.
Serialization class submodule: the method comprises the steps of establishing a mapping relation between json objects transmitted by a front end and database model classes;
the establishment of the mapping relation between json objects and database model classes is the function provided by the django framework, and the data access flow is as follows:
(1) The Web or cli transmits json format data to the Web service through a restful interface (the interface is generated through an interface class submodule);
(2) The Django rest framework component in django converts json data into model objects; the model object is the object of the database model class described above, and represents a record in the database table.
(3) The model object data is saved to the database of step 1 through the ORM.
json objects may be exemplified by the following codes:
the above is a json object, corresponding to one model object in the model class;
from the above analysis, it can be seen that a database table, a database model class, a class object and a database are generated in the database model class submodule according to the XML configuration file;
the serialization class submodule generates a model object according to the json object.
The definition of the database table corresponds to the database model class; one record in the database table corresponds to one model object.
In the conventional technology, if the database is to be directly operated, a developer is required to write SQL sentences for operation. According to the technical scheme, through the ORM technology, a developer can directly complete the adding, deleting and checking operation of the database by operating one model object in an object-oriented mode without writing SQL sentences.
Interface class submodule: the method comprises the steps of generating a restful interface according to an XML configuration file;
taking the xml configuration file as an example, generating a Restful interface according to django rest framework and the xml configuration file, wherein django rest framework component is open source software developed by a third party organization aiming at the django framework, and the Restful interface can be generated according to class definition;
the operation process is as follows:
the django rest framework component generates two class codes according to the XML configuration file and generates a url route registration code, namely, the restful interface can be automatically generated by the framework.
The following are class codes
class NetworkSerializer (serialisers. ModelSerializer): serialization class definition, conversion between json and model.
class Meta, meta definition
model = Network bound model class
field= "__ all __" is bound to a field of the model class, __ all __ identifies that all fields are bound.
class NetworkViewSet (views. ModelViewset): view class definition, interact with restful interface
serialiser_class = networkserialiser bound serialization class
queryset=network.
filter_class = NetworkFilter binding filter class, used to filter data.
Below # in the url. Py file is the routing rule
router=defaultrouter () route definition
Router. Register ('network', network ViewSet) binds the restful interface to the view class
The route generation rule is only responsible for the two latter rows, the view class is responsible for interacting with the restful interface, and the rear-end json data is acquired through the seriizer class and filtered and displayed to the front end, or the received front-end data is transferred to the sirializer class.
Page routing rule generation sub-module: and generating page routing rules for the restful interface registration according to the XML configuration file.
The matching relation of the sub-modules is as follows:
the configuration of the pages of any embedded device can be managed through an XML configuration file in the embodiment, and the database model submodule firstly generates a database based on the XML configuration file, wherein the database consists of database tables; the database model class and the database represent the corresponding relation;
the page routing rule generation submodule generates a restful interface and a routing rule according to the XML configuration file;
the front end calls the interface and the routing rule to send the json object to the serialization class submodule;
the serialization class submodule converts the json object into a model object;
the database model submodule writes the model object into a database table in the database, so that the xml configuration file of the front-end page is expressed;
in the maintenance process, maintenance personnel need to upload the XML configuration file of the changed configuration, so that the front-end page can be managed and maintained.
When a user changes the relevant configuration of the page, one or more json objects are generated, the json objects are converted into model objects through the serialization class submodule, and the database model submodule writes the model objects into a database table to realize modification of the database.
The innovation point of the invention is that:
automatically generating a database table, a database model class, a restful interface and a page route based on an XML page configuration file; the conversion between json objects and model objects is an open source prior art; through the automatic generation of the database table, the database model class, the restful interface and the page route based on the XML page configuration file, when a user modifies the front-end page data, through the conversion between json objects and model objects, the model objects and the database model class have mapping relations, the database model class and the database table have mapping keys, the model objects can be filled in the database table, so that the update of the database file is realized, and the operation of adding, checking, modifying and deleting the front-end page functions is realized.
In addition, the embodiment also provides a management method of the configuration data of the internet of things device based on the XML parsing module, referring to fig. 3 and 4, which includes the following steps:
step 1: the front-end application acquires the page routing rule from the page routing rule generation submodule;
step 2: registering a restful interface according to a page routing rule, and sending configuration data to a serialization class sub-module through the restful interface in a json object mode; the serialization class submodule establishes a mapping from the json object to the database model class to obtain the database model class;
step 3: the database model submodule maps the database model class into a database table in the database, and realizes the operations of adding, checking, modifying and deleting the configuration data in the database table.
In this embodiment, the page routing rule in step 1, the restful interface in step 2, the database model class and the mapping relation between the database tables are automatically generated according to the XML page configuration file, and the software developer does not need to write the database tables, the interface configuration file and the routing rule manually, which can effectively reduce the working strength of the operator.
And combining with the CN201910596120.5 and CN201910682579.7 patents, the whole flow function of configuration management can be finished, and a user can finish the configuration of front-end pages, CLI and the like and the parameter management in the equipment by only defining XML rules.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
