Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.
Example one
Referring to fig. 2, a flowchart of steps of a method for transmitting a vehicle-mounted message according to an embodiment of the present invention includes steps 101 to 103, where the steps specifically include:
step 101, receiving message data sent by a sending end, wherein the message data comprises message content and message type, and the message type comprises a category value and a sub-classification value.
Specifically, the transmitting end may include: the flow end, the smart home end, the music end and the like can be changed and modified according to the actual application requirements, and the method is not limited herein. The message content refers to content information which is required to be sent to a vehicle end by a sending end, wherein the category value refers to a numerical value in original traditional message content verification, and the sub-classification value refers to a corresponding numerical value which is newly added for the sub-category information of each category of messages in the technical scheme.
And 102, verifying the category value and the sub-classification value in the message data through a preset information verification rule, and determining that the message content is legal when the category value and the sub-classification value are determined to exist in the information verification rule.
Specifically, the information validation rule is preset with a corresponding category value and a sub-classification value, and when the correspondence between the category value and the sub-classification value carried in the message content sent by the sending end is consistent with the numerical correspondence in the information validation rule, the message content is considered to be legal. In the process of verifying the category value and the sub-category value, the verification order of the category value and the sub-category value may be performed simultaneously or separately, and is not limited herein. In this embodiment, the information verification rule may include an information verification table or different types of files in other forms.
And 103, processing the message content according to the message type after the message content is determined to be legal.
Specifically, various sending ends send messages to a vehicle end through a message channel based on a message protocol, the vehicle end is provided with a special pushing SDK for receiving the messages sent by the sending end, when the vehicle end receives the messages, the legality judgment and processing are carried out, and if the messages are legal, the messages are displayed according to a design scheme. Fig. 3 is a schematic diagram of an information verification rule in the embodiment of the present invention. Firstly, each message under each type of message is assigned with a sub-classification value (subtype), the subtypes are written in a local library of the vehicle machine in advance, and only when the subtype of the message band received by the vehicle machine already exists and is consistent with the corresponding relation between the subtype and the category value, the message band is considered to be legal and is processed and displayed. Taking the smart home class message as an example, the following is a definition case of a subtype, where [ scene execution result prompt ] a subtype value of the class message is 1, and [ geo-fence ] a subtype value of the class message is 2. Based on the agreement between the cloud and the vehicle end in fig. 3, the smart home as the sender sends the value in fig. 3, the vehicle end prestores the value in fig. 3 in the vehicle local library, and when the vehicle receives the message, the vehicle verifies the message, if the message is verified to be consistent, that is, the received type value is 13, and the sub-classification value is 1, the scene execution result prompts that the type message is legal to display; for another example: if the received category value is 13 and the sub-category value is 2, the geo-fence type message is considered to be legitimately displayed.
In this embodiment, after the verifying the category value and the sub-classification value in the message data by a preset information verification rule, the method further includes: and when the corresponding relation between the category value and the sub-classification value is determined to be inconsistent with the information verification rule, determining that the message content is illegal.
In this embodiment, after the determining that the message content is illegal, the method further includes: and deleting the message data. The action of deleting after the message content is determined to be illegal can prevent data from causing redundancy in the message center, and the efficiency of data processing can be reduced due to excessive invalid data storage, so that the efficiency of the processing efficiency of the message center can be ensured by deleting illegal data in time, and on the other hand, the legality of the transmission of the message content in the message center can also be ensured.
In another embodiment, the message type further comprises a tag classification value; before the processing the message content according to the message type, the method further includes: and verifying the mark classification value through a preset information verification rule, and displaying a mark image corresponding to the mark classification value when the corresponding relation among the mark classification value, the category value and the sub-classification value is consistent with the information verification rule.
The technical scheme has the advantages that: 1) the situation that unsafe experience is caused due to the fact that some new messages are sent to the car machine randomly and the content of the car machine messages is not in compliance is avoided; 2) for a sub-message scene under a certain type of message, different processing logics are available, and the method can be easily realized.
