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. 2, a flowchart of steps of a vehicle-mounted message transmission method according to an embodiment of the present invention includes steps 101 to 103, where the steps are specifically as follows:
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 intelligent home end, the music end and the like can be changed and modified according to actual application requirements, and the method is not limited herein. The message content refers to content information which needs to be sent to the vehicle-mounted terminal by the sending terminal, wherein the category value refers to a numerical value in the verification of the original traditional message content, and the sub-classification value refers to a corresponding numerical value newly added for sub-category information of each type of message in the technical scheme.
Step 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 determining that the category value and the sub-classification value exist in the information verification rule.
Specifically, corresponding category values and sub-classification values are preset in the information verification rule, and when the corresponding relation between the category values and the sub-classification values carried in the message content sent by the sending end is consistent with the numerical corresponding relation in the information verification rule, the message content is considered to be legal. In the verification of 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, which is not limited herein. In this technical solution, the information verification rule may include an information verification table or a different type of file existing in other forms.
And step 103, after the message content is determined to be legal, processing the message content according to the message type.
Specifically, various sending terminals send messages to the vehicle terminal through a message channel based on a message protocol, the vehicle terminal is provided with a special push SDK for receiving the messages sent by the sender, and when the vehicle terminal receives the messages, the vehicle terminal judges and processes the legality, if the legality is legal, the vehicle terminal displays the legality according to the design scheme. Fig. 3 is a schematic diagram of an information verification rule according to an embodiment of the present invention. First, sub-classification values (subtypes) are allocated to each message under each type of message, and the subtypes are written in a local library of the vehicle machine in advance, and are considered legal and are processed and displayed only when the subtypes of the message bands received by the vehicle machine exist and keep the correspondence with the type values consistent. Taking the smart home class message as an example, the following is the definition case of subtype, wherein the subtype value of the [ scene execution result prompt ] class message is 1, and the subtype value of the [ geofence ] class message is 2. Based on the fact that the intelligent home as a sender uses the value of the figure 3 to send based on the fact that the figure 3 serves as a cloud end and a vehicle side, the vehicle side can pre-store the figure 3 in a local library of the vehicle, when the vehicle receives the message, verification processing is carried out, if the verification is consistent, namely the received type value is 13, and when the sub-classification value is 1, the scene execution result is considered to prompt that the type message is legal to display; another example is: and when the received category value is 13 and the sub-category value is 2, the geofence type message is considered legal for display.
In this embodiment, after the verifying the category value and the sub-category 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 not consistent 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 the illegal message content can prevent redundancy of the data in the message center, and the invalid data is stored too much to reduce the efficiency of data processing, so that the illegal data is deleted timely to ensure the high efficiency of the processing efficiency of the message center, and the validity of the transmission of the message content in the message center can be ensured.
In another embodiment, the message type further includes a flag classification value; before the processing of the message content according to the message type, the method further comprises: 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 determined to be consistent with the information verification rule.
The technical scheme has the advantages that: 1) The method has the advantages that the phenomenon that certain new messages are sent to the vehicle-mounted device on will is avoided, the content of the vehicle-mounted device messages is not compliant, and unsafe experience is caused; 2) For the sub-message scene under a certain type of message, different processing logic exists, and the sub-message scene can be easily realized.
