It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details. In some instances, well known means have not been described in detail so as not to obscure the present invention.
Referring to fig. 2 to 3, an embodiment of the present invention provides a management method for a car machine to request to download an OTA software package, including the following steps:
step S1, the CDN node responds to a received OTA software package downloading request sent by a vehicle machine, and obtains a user account and an IP address of the vehicle machine according to the downloading request; wherein, each vehicle machine is pre-allocated with a unique IP address;
specifically, in the actual application process, a user logs in a user account on a vehicle machine, and operates the vehicle machine to send an OTA software package downloading request in a logging state, wherein the OTA software package downloading request comprises the content of the request for downloading the OTA software package, the user account and the IP address of the vehicle machine;
step S2, the CDN node verifies whether the user account is legal and whether the IP address is a legal IP address;
specifically, the verification of the user account is performed by using a token, for example, that is, a user registers an account in advance to obtain a user account, the user account is assigned with a unique token, and the server stores an association relationship between the token and the user account, when the user logs in the user account to perform interaction with the server, the token is carried in the sent data, and accordingly, after receiving the data sent by the vehicle, the server extracts the token and the user account from the data, and determines whether the user account is legal according to the association relationship between the token and the user account stored by the server. It should be noted that the above is only an example, and the present embodiment is not limited to this, and other authentication methods may be used to authenticate the user account.
Step S31, if the user account is a legal account and the IP address is a legal IP address, the CDN node acquires an OTA software package from an OTA source server and returns the OTA software package to the vehicle machine;
step S32, if the user account is an illegal account, or the IP address is an illegal IP address, the CDN node denies access to the car machine.
The method comprises the steps that double verification is carried out by using a current user account and a vehicle machine IP address of a vehicle machine request for downloading an OTA software package, and if the user account is a legal account and the IP address is a legal IP address, the CDN node acquires the OTA software package from an OTA source server and returns the OTA software package to the vehicle machine; and if the user account is an illegal account or the IP address is an illegal IP address, the CDN node refuses the access of the vehicle machine, so that a legal user can download the OTA software package.
Further, the verifying whether the IP address is a valid IP address in step S2 includes:
and judging whether the IP address is in a preset IP address white list or not, or judging whether the IP address accords with a preset IP rule or not.
Specifically, in an example, referring to fig. 4, the step S2 specifically includes:
the CDN node generates an IP authentication request according to the IP address, and sends the IP authentication request to a serverless computing platform to request the serverless computing platform to verify whether the IP address is a legal IP address or not, and receives an IP authentication result returned by the serverless computing platform; and the IP authentication result comprises whether the IP address is in a preset IP address white list or whether the IP address accords with a preset IP rule.
Specifically, the serverless computing platform is a third-party platform providing computing functions, provides a series of matching services, only needs to write down the table name of the database on the configuration file, then the data can be stored in the corresponding database, and provides a series of function computing templates, only needs to write the required configuration in the configuration file, and can automatically and efficiently complete the computing task. In this embodiment, an IP address white list or an IP rule (also referred to as an IP filtering rule) is written in a configuration file, and a function computation template provided by a serverless computing platform is utilized, so that whether the IP address is in a preset IP address white list or whether the IP address meets the preset IP rule can be determined; the IP address white list refers to a plurality of specific IP addresses, and if the vehicle machine IP address is the same as any one of the IP address white list, the IP address is in a preset IP address white list; the IP rule may be set to an IP address range, i.e., determine whether an IP address is within the IP address range.
Specifically, this embodiment provides 2 IP address verification methods: in the first mode, the server computing platform responds to an IP authentication request received from a CDN node, acquires a corresponding IP address according to the IP authentication request, calls a corresponding function and performs operation to determine whether the IP address is in a preset IP address white list or not; if the answer is positive, the answer is a legal IP address, and true is returned to the CDN node, and if the answer is negative, the answer is an illegal IP address, and false is returned to the CDN node. In a second mode, the serverless computing platform responds to an IP authentication request of a received CDN node, acquires a corresponding IP address according to the IP authentication request, calls a corresponding function and carries out operation to determine whether the IP address accords with a preset IP rule or not; if the answer is positive, the answer is a legal IP address, and true is returned to the CDN node, and if the answer is negative, the answer is an illegal IP address, and false is returned to the CDN node. It is understood that the above two modes can be applied independently or simultaneously.
In another example, the CDN node verifies whether the user account is legal and verifies whether the IP address is a legal IP address, specifically:
the CDN node verifies whether the user account is legal or not, and when the user account is a legal account, the CDN node further verifies whether the IP address is a legal IP address or not; and when the user account is an illegal account, the CDN node refuses the access of the vehicle machine.
It is understood that in this example, the IP address authentication is continued only when the user account is legitimate, and does not need to be performed every time, which in this example is equivalent to a secondary authentication.
