Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.
Because the label containing the identity mark keyword attribute, namely the identity mark keyword attribute label, possibly exists in the current extensible markup language file, and the label containing the identity mark keyword attribute label plays a role of link, the object data marked by the label with the identity mark keyword attribute label is not an available value with practical significance, and further, when the object data of the extensible markup language file is stored through a corresponding class, the corresponding object data cannot be obtained through the class object of the identity mark keyword attribute label, so that the overall reliability of the obtained vehicle diagnostic data is difficult to ensure, and the accuracy of the analysis result of the vehicle diagnostic data is further reduced.
The core of the application is to provide a data acquisition method, so as to relatively ensure that the object data under the identification keyword attribute label in the extensible markup language file is normally acquired, and further ensure the overall reliability when the data in the extensible markup language file is acquired. Another core of the present application is to provide a data acquisition apparatus, device, and medium.
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
Fig. 1 is a flowchart of a data acquisition method according to an embodiment of the present application. Referring to fig. 1, the data acquisition method specifically includes the steps of:
step S10: and receiving an acquisition instruction for the data in the identification keyword attribute tag.
Step S11: and searching a class object of a common label corresponding to the identification keyword attribute label in the extensible markup language file in a preset corresponding relation.
It should be noted that the extensible markup language (XML, extensible Markup Language), a subset of the standard generic markup language, is a markup language used to mark electronic files to be structured.
The method comprises the steps of searching a class object of a common label corresponding to an identification keyword attribute label in a preset corresponding relation when acquiring object data under the identification keyword attribute label in an extensible markup language file, namely responding to a data acquisition instruction for acquiring the object data under the identification keyword attribute label, wherein the identification keyword attribute label refers to the extensible markup language label with the identification keyword attribute parameter. It can be understood that, because the id keyword attribute tag plays a role of linking, the object data under the id keyword attribute tag should be identical to the object data under the corresponding normal tag, where the normal tag refers to an extensible markup language tag different from the id keyword attribute tag in the extensible markup language file. The key point of the step is that the corresponding relation between the identification keyword attribute label and the class object corresponding to the common label is recorded in advance, and then when the object data under the identification keyword attribute label is obtained, the class object of the common label corresponding to the identification keyword attribute label is searched through the corresponding relation.
The class object in the above step refers to an instantiation object generated by a class (class), which may be specifically a class instance object generated by a class, a class derivative object, and the like, where a class is a collection of things or events that have common features to a group, and a class object is an actual application object of the class, and has actual data access capability. Currently, corresponding classes are generated in advance according to the labels in the extensible markup language file and are used for storing the data objects under the labels by the class objects of the classes, so when the data objects under the common labels corresponding to the identification key attribute labels are obtained in the step, the class objects corresponding to the common labels are obtained, and further the corresponding data objects are obtained through the class objects.
Step S12: and acquiring the data object under the common label through the class object.
Step S13: and outputting the data object to a data acquisition result.
The above steps are that after the class object of the common label corresponding to the attribute label of the identification key is searched in the corresponding relation, the data object of the common label, namely the data object corresponding to the attribute label of the identification key, is obtained through the class object.
According to the data acquisition method, an acquisition instruction of data in the identification keyword attribute tag is received, a class object of a common tag corresponding to the identification keyword attribute tag in the extensible markup language file is searched in a preset corresponding relation, and then the data object under the common tag is acquired through the class object, and the data object is output as a data acquisition result. The method is characterized in that the corresponding relation between the identity mark keyword attribute label and the corresponding common label is recorded in advance, and then the real data object source of the identity mark keyword attribute label to be acquired is searched according to the corresponding relation, namely the class object of the corresponding common label, and the data object corresponding to the identity mark keyword attribute label is acquired as a data acquisition result, so that the method can relatively ensure that the object data under the identity mark keyword attribute label in the extensible markup language file is normally acquired, and ensure the overall reliability when the data in the extensible markup language file is acquired.
Fig. 2 is a flowchart of another data acquisition method according to an embodiment of the present application. Referring to fig. 2, the data acquisition method specifically includes the steps of:
step S20: and receiving an acquisition instruction for the data in the identification keyword attribute tag.
Step S21: and retrieving a base class pointer object of a common label corresponding to the identification keyword attribute label in the extensible markup language file in a preset corresponding relation.
It should be noted that, in this embodiment, an association relationship between an attribute tag of an identification keyword and a base class pointer object of a common tag is recorded in a preset corresponding relationship, where the base class pointer object is a pointer object generated by a base class, and the base class refers to a class (class) type that includes commonalities of all entities, that is, the base class can be converted into other classes.
In addition, the value of the pointer object directly points to (points to) a certain address in the computer memory, and as the variable unit where the required data object is located can be found through the address, the data object in the variable unit can be directly obtained, and thus the operations of initializing the class, distributing a block area in the memory, assigning values to member variables and the like do not need to be performed in advance, and the overall efficiency of obtaining the data object is relatively improved. In addition, because the pointer directivity of the pointer object can be modified according to the requirement, the same pointer object can point to the variable unit where different data objects are located, and the purpose of acquiring different data objects through the same pointer object is further achieved.
Step S22: the data object under the common label is obtained through the derived class pointer object converted by the base class pointer object.
The method for acquiring the data object is provided by adopting the base class pointer object, the data object of the corresponding type can be acquired by converting the single base class pointer object into different derivative class pointer objects, and the polymorphism mode is utilized to improve the diversity and the high efficiency flexibility of acquiring the data object by the user.
Step S23: and outputting the data object to a data acquisition result.
On the basis of the foregoing embodiment, as a preferred implementation manner, the receiving an instruction for obtaining data in the identifier key attribute tag, and searching, in a preset correspondence, a base class pointer object of a common tag corresponding to the identifier key attribute tag in the extensible markup language file, includes:
and receiving an acquisition instruction of the data in the identification keyword attribute tag, and searching a base class pointer object corresponding to the identification keyword attribute tag in the extensible markup language file in a preset association array.
The key point of the embodiment is that the basic class pointer object corresponding to the identification keyword attribute tag in the extensible markup language file is searched in a preset association array, namely, the corresponding relation between the identification keyword attribute tag and the basic class pointer object is recorded in the association array in advance.
It should be noted that, the structure of the association array is Map < Key, value >, where Key is a Key, value is a Value, the association array is an object that maps a Key to a Value, one mapping cannot contain repeated keys, and each Key can only be mapped to one Value at most. Because the association array has the advantages of high flexibility, easy expansion and low coupling, the association array can store the numerical mapping relation, so that the maintainability and the modification flexibility of the numerical mapping relation are improved while the accuracy of the numerical mapping relation is ensured, and the overall reliability of the data acquisition process is ensured.
In addition, as a preferred embodiment, before retrieving the class object of the common tag corresponding to the identification keyword attribute tag in the extensible markup language file in the preset correspondence, the method further includes:
judging whether the acquisition instruction is legal or not;
if yes, the step of searching the generic object of the common label corresponding to the identification keyword attribute label in the extensible markup language file in the preset corresponding relation is executed.
It should be noted that, since the acquiring instruction is transmitted by the user and is used for acquiring the corresponding data object, and the data objects that can be accessed are different for users with different authorities, in order to avoid users with lower authorities accessing the data object with high authority requirements, the embodiment determines whether the acquiring instruction is legal before executing the step of searching the generic object of the generic tag corresponding to the identification keyword attribute tag in the extensible markup language file in the preset corresponding relationship, and if so, the step of searching the generic object of the generic tag corresponding to the identification keyword attribute tag in the extensible markup language file in the preset corresponding relationship can be successfully executed, so as to ensure the access security of the data object.
Furthermore, as a preferred embodiment, after outputting the data object as a data acquisition result, the method further includes:
and storing the data acquisition result according to the field classification.
It should be noted that, in this embodiment, after the data object is output as the data acquisition result, the data object is stored according to the field classification of the data acquisition result, so that the data acquisition result can be repeatedly used, and meanwhile, the acquisition efficiency of the data acquisition result after the data acquisition result is stored can be improved.
On the basis of the above-described series of embodiments, as a preferred embodiment, the data object includes vehicle diagnostic data based on an open diagnostic data exchange system.
It should be noted that the open diagnostic data exchange system (ODX, open Diagnostic data eXchange) is an extensible markup language data format for describing vehicle diagnostic related data, and is mainly used for exchanging diagnostic data between an OEM and its provider. There is now an increasing trend for OEMs to build standardized diagnostic procedures that are centered on the open diagnostic data exchange system format.
Because the research and development based on the automobile diagnosis standard at present belongs to the emerging field, the acquisition of the corresponding data object according to the identification keyword attribute tag is a new technology related to the automobile diagnosis research and development field of the open diagnosis data exchange system, and therefore the problem of acquiring the corresponding object according to the identification keyword attribute tag is not related in the existing business field. According to the embodiment, the data object corresponding to the identification keyword attribute tag can be directly obtained according to the identification keyword attribute contained in the extensible markup language tag of the open diagnosis data exchange system in the field of automobile diagnosis research and development of the open diagnosis data exchange system, and the overall reliability of obtaining the automobile diagnosis data in the field of automobile diagnosis research and development of the open diagnosis data exchange system is ensured.
In addition, the application also provides an embodiment under a specific application scene of data acquisition, which comprises the following specific steps:
the first step: defining a base class containing virtual functions and a global Map taking an identity mark keyword attribute tag and a base class pointer object as a key value pair;
and a second step of: in the extensible markup language tag analysis link related to the ID attribute, inserting an ID keyword attribute tag and a base class pointer object into a global Map;
and a third step of: in the link of calling the identity mark key word, map [ identity mark key word attribute label ] is used to obtain a base class pointer object;
fourth step: strongly converting the base class pointer object into a specific derivative class pointer object;
fifth step: and accessing the data object corresponding to the identification key attribute tag through the derivative class pointer object.
