Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
An embodiment of the present application provides a method for generating an identifier of a vehicle-mounted device, and as shown in fig. 1, a flowchart of the method for generating an identifier of a vehicle-mounted device in the embodiment of the present application is provided, where the method is executed by a server, and the method at least includes the following steps S110 to S140:
step S110, receiving a network request of a vehicle end, wherein the network request is used for acquiring an equipment identifier of the vehicle end, and the network request comprises an equipment channel keyword and an original equipment identifier.
The vehicle-mounted device identifier generation method in the embodiment of the application may be executed by a server, and when generating a vehicle-mounted device identifier, a network request of a vehicle end needs to be received first, where the network request may be understood as a request for obtaining a vehicle-mounted device identifier, that is, the vehicle end may request the server to obtain a unique identifier of the vehicle-mounted device according to actual business needs, and the network request needs to carry parameters such as a device channel keyword and an original device identifier, where the device channel keyword may be understood as keyword information for distinguishing different device manufacturers, for example, the device channel keyword of a device manufacturer a is "bydauto", the device channel keyword of a device manufacturer B is "baicmotor", and the original device identifier may be understood as a device unique identifier, that is, device ID, generated by each device manufacturer based on a self-defined coding rule thereof.
The specific equipment manufacturer can be located through the equipment channel keywords, and the specific equipment in the equipment manufacturer can be located through the original equipment identification.
The vehicle-mounted equipment identifier can be an SN (serial number) of the equipment, namely a product serial number, is a concept introduced for verifying 'legal identity of a product', and is an identifier used for guaranteeing the copyright rights and interests of users and enjoying legal services. The vehicle-mounted device identifier may also be an ICCID (integrated circuit card identification, i.e., an SIM card number, which is an identification card equivalent to a Mobile phone number.
Of course, in addition to the above listed several types of device identifiers, the vehicle-mounted device identifier generation method in the embodiment of the present application may also be applied to other more types of device identifiers, and those skilled in the art may flexibly select in the field to maintain the compatibility of the device identifiers.
Step S120, according to the network request, determining whether a global device identifier corresponding to the network request exists in a device identifier database.
After receiving the network request, whether a global device identifier corresponding to the network request exists may be queried in a device identifier database established in advance, where the global device identifier may be understood as a device identifier generated based on the vehicle-mounted device identifier generation method according to the embodiment of the present application, and has global uniqueness.
If the query can be made, it is described that the global unique identifier has been generated for the device of the device vendor before, then, in order to avoid a situation that the same device is assigned with a plurality of different global unique identifiers, at this time, a subsequent device identifier generation operation does not need to be performed, and if the query cannot be made, it is described that the device of the device vendor does not have a corresponding global unique identifier yet, a subsequent device identifier generation operation needs to be performed.
Step S130, in a case that the global device identifier corresponding to the network request does not exist in the device identifier database, generating a global device identifier corresponding to the network request by using a preset global device identifier generation policy.
If the global device identifier corresponding to the network request cannot be queried in the device identifier database, a unique global device identifier may be generated for the device of the device manufacturer by using a global device identifier generation policy set in advance. The preset global device identification generation strategy can be used for unifying the coded digit number, the pattern and the like, and can distinguish different situations by representing different meanings through different numbers, letters or symbols in different digit numbers. Of course, those skilled in the art may also flexibly define the identifier according to actual requirements as long as the generated identifier is globally unique and uniform in format.
And step S140, returning the global device identifier to the vehicle end, and correspondingly storing the global device identifier, the device channel keyword and the original device identifier into the device identifier database.
After the newly generated global device identifier is obtained, on one hand, the newly generated global device identifier needs to be returned to the vehicle end to enable the vehicle end to perform operations such as subsequent service processing, and on the other hand, the newly generated global device identifier needs to be correspondingly stored in the device identifier database together with the device channel keyword and the original device identifier in the network request, that is, a relationship mapping is established between the original device identifier and the newly generated global device identifier. For example, a certain original device id of the device vendor a is BYD1000100001, which may be mapped to a newly generated global device id X0120211203ABCDEFG, where the newly generated global device id can ensure the uniqueness of the device id among all different device vendors, and when the device id of the device is requested again by the subsequent vehicle end, the original device id may be replaced by the newly generated global device id.
The vehicle-mounted equipment identifier generation method provided by the embodiment of the application generates globally unique equipment identifiers with uniform format aiming at the vehicle-mounted equipment of different equipment manufacturers, and solves the problems that the equipment unique identifiers of multiple equipment manufacturers are possibly repeated, services or applications which need to run on multiple equipment do not have globally unique equipment identifiers, and the like.
In one embodiment of the present application, before receiving the network request from the vehicle, the method further includes: registering equipment channel keywords for each vehicle end; distributing equipment channel identification for each vehicle end according to the equipment channel keyword of each vehicle end; and correspondingly storing the equipment channel keywords of each vehicle end and the equipment channel identification into the equipment identification database.
In the embodiment of the present application, before generating the global device identifier, corresponding device channel information may be established for different device manufacturers to serve as a basis for subsequently generating the global device identifier, as shown in fig. 2, which provides a schematic diagram of a construction process of the device channel information in the embodiment of the present application.
Firstly, a corresponding equipment channel is newly established for the vehicle machines of different equipment manufacturers, for example, a channel of a newly established equipment manufacturer A and a channel of an equipment manufacturer B. Then, corresponding device channel keywords are registered for different device channels, for example, the device channel keyword is "bydauto" for the device manufacturer a channel, the device channel keyword is "baicimotor" for the device manufacturer B channel, and only the registered device channel keywords can generate subsequent global device identifiers.
Then, an equipment channel identifier is allocated to each equipment channel keyword, and the generation rule of the equipment channel identifier may be customized, for example, the equipment channel identifier "X01" is allocated to the equipment channel keyword "bydauto", the equipment channel identifier "X02" is allocated to the equipment channel keyword "basic", and so on. And finally, correspondingly storing the obtained equipment channel keywords and the equipment channel identification into an equipment identification database, thereby completing the construction process of the equipment channel information.
In one embodiment of the present application, after receiving the network request from the vehicle, the method further includes: determining whether the device channel keyword exists in the device identification database; if yes, determining whether a global device identifier corresponding to the network request exists in a device identifier database according to the network request; if not, returning error prompt information.
After receiving a network request of a vehicle end, the embodiment of the application can firstly query the device identification database by using the device channel keywords carried in the network request, and if the query can be made, the device manufacturer corresponding to the request can register the corresponding device channel keywords, and then the subsequent global device identification generation operation can be further executed. If the device channel keyword cannot be inquired, the device manufacturer does not register the device channel keyword, and then subsequent global device identifier generation operation cannot be executed, so that the error prompt information is directly returned.
In an embodiment of the application, the generating a global device identifier corresponding to the network request by using a preset global device identifier generation policy includes: determining a corresponding equipment channel identifier in the equipment identifier database according to the equipment channel keyword; acquiring the system time of a current server; and generating a global device identifier corresponding to the network request according to the device channel identifier and the current server system time.
The embodiment of the application provides a preset global device identifier generation strategy, and specifically, a corresponding device channel identifier is firstly queried in a device identifier database according to a device channel keyword, for example, a device channel identifier corresponding to a device channel keyword "bydauto" is queried in the device identifier database to be "X01", the device channel identifier is used for distinguishing different device channels or device manufacturers in an identifier form, and specifically, the preset global device identifier generation strategy can be flexibly defined according to actual service requirements.
Then, the server system time when generating the global device identifier can be added behind the device channel identifier, and finally, the global device identifier corresponding to the network request is generated according to the device channel identifier and the current server system time, so that no matter how many kinds of values of the code of the original device identifier exist, the correspondence can be found in a new rule, and the condition that the global device identifier is not repeated is ensured. For example, the newly generated global device ID may be in the format of X × 20211101 × and the middle time portion will always be different as time goes by, thus ensuring that the newly generated global device ID can never be repeated, similar to the self-increment of the ID.
In an embodiment of the present application, the generating a global device identifier corresponding to the network request according to the device channel identifier and the current server system time includes: processing the original equipment identification based on a preset abstract algorithm to obtain a random character string; and generating a global equipment identifier corresponding to the network request according to the equipment channel identifier, the current server system time and the random character string.
Based on the foregoing embodiment, for the last part of "X × 20211101 × may be generated according to the original device identification, and it may be referred to using a digest algorithm, such as md (message digest) message digest, sha (secure Hash algorithm), mac (message Authentication code) message Authentication code, and so on, to generate a random string with a fixed length, which has higher generation efficiency than the ordinary random string generation method.
In addition, it should be noted that, if the original device identifications generated by the two device manufacturers are completely the same, at this time, the random string portions obtained according to the above-mentioned abstract algorithm adopted in the embodiment of the present application may be the same, but since the former "X" portion represents the device channel, even if the latter random string portion is the same, two different global device identifications can still be generated according to the former "X" portion, so that the generation efficiency for the global device identification is higher, and the applicability is more flexible, which is one of the advantages of the preset global device identification generation strategy designed by the present application.
Of course, in addition to the above manner, in the embodiment of the present application, a random character string may also be generated not based on the original device identifier, but an ordinary random character string generation manner may be adopted, and after the random character string is generated each time, whether the generated random character string is repeated with a previously generated random character string may be determined, and if so, the random character string may be regenerated again.
In an embodiment of the present application, after determining whether a global device identifier corresponding to the network request exists in a device identifier database according to the network request, the method further includes: and under the condition that the global equipment identifier corresponding to the network request exists in the equipment identifier database, directly returning the global equipment identifier corresponding to the network request in the equipment identifier database to the vehicle end.
As described above, if the global device Identifier corresponding to the network request already exists in the device Identifier database, then the corresponding global device Identifier is directly returned to the vehicle end, and compared with a manner of using a UUID (universal Unique Identifier), it is possible to ensure that the global device identifiers generated by the same original device Identifier are consistent, thereby avoiding a situation that the same device is allocated with a plurality of different global device identifiers, and facilitating subsequent vehicle end service processing.
In order to facilitate understanding of the foregoing embodiments, as shown in fig. 3, a schematic diagram of a vehicle-mounted device identifier generation flow in the embodiment of the present application is provided. Firstly, a service end receives a network request of a vehicle end, wherein the request carries parameters such as equipment channel keywords, original equipment identification device ID and the like. Then, checking whether the device channel keyword exists in a device identification database, if not, directly returning an error code, if so, further checking whether the device channel keyword and the original device identification correspond to a generated global device identification, if so, directly returning the corresponding global device identification, and if not, generating a new global device identification by using a preset global device identification generation strategy. And finally, correspondingly storing the new global equipment identification, the equipment channel keyword and the original equipment identification into an equipment identification database.
The vehicle-mounted equipment identification generation method solves the problem that equipment unique identifications of multiple equipment manufacturers are possibly repeated, and solves the problem that services needing to be operated on multiple kinds of equipment do not have global unique equipment identifications. For example, a certain vehicle-mounted APP needs to run on the vehicle of the equipment manufacturer a and the vehicle of the equipment manufacturer B simultaneously, and in the equipment and systems such as the automobile data recorder, the service itself does not activate the binding constraint and function, so that a globally unique device identifier is needed to distinguish different users, so as to know which equipment is the service data generated by which user, and the service data is stored to facilitate subsequent query.
In addition, the vehicle-mounted equipment identification generation method further solves the problems that the unique identification digits and the unique patterns are not uniform due to the fact that equipment identification rules of multiple equipment manufacturers are not uniform.
The embodiment of the present application further provides a method for acquiring a vehicle-mounted device identifier, and as shown in fig. 4, a schematic flow chart of the method for acquiring a vehicle-mounted device identifier in the embodiment of the present application is provided, where the method is executed by a vehicle end, and the method at least includes the following steps S410 to S430:

step S420, under the condition that the global device identification of the vehicle-mounted device cannot be obtained from the local of the vehicle end, sending a network request to a server end, wherein the network request is used for obtaining the device identification of the vehicle end, and the network request comprises a device channel keyword and an original device identification;
step S430, receiving the global device identification of the vehicle-mounted device returned by the server and storing the global device identification to the local of the vehicle; the global device identifier of the vehicle-mounted device is obtained based on any one of the vehicle-mounted device identifier generation methods.
As shown in fig. 5, a schematic diagram of an in-vehicle device identifier obtaining flow in the embodiment of the present application is provided. Firstly, the vehicle side preferentially acquires the global equipment identifier of the desired vehicle-mounted equipment from the local storage of the vehicle side, if the local storage does not have the corresponding global equipment identifier, the equipment channel keyword set in the vehicle side APP and the original equipment identifier device ID are used as parameters and transmitted to the server side, so that the global equipment identifier is acquired from the server side, and finally, the global equipment identifier returned by the server side is received and stored locally at the vehicle side for subsequent use. The local storage mode of the vehicle-side APP is not limited, and the vehicle-side APP can be files or Android lightweight data storage SharedPreferences and the like.
