Token＝HMAC_SHA256(Uri+Timestamp+HTTP body，K2)；
K2＝HMAC_SHA256(N1,SecretKey)；
n1 is a safe random number, and the format is hexadecimal capital;
timestamp: the timestamp of the occurrence of the request is formatted in hexadecimal uppercase.
The HMAC_SHA256 operation is used, a secret key and a secure random number are used as inputs to generate a message digest K2, the message digest K2 is used as a secret key again, and information such as parameters Uri, HTTP body and a time stamp are used as secondary inputs to generate authentication information Token.

It should be noted that, the operation and maintenance system does not need to analyze and configure domain name information, so that persistent storage is adopted, and the storage performance is improved.
The embodiment of the application also provides a service distribution method based on the hybrid management system, which is applied to the edge subsystem.
In this embodiment, the service distribution method includes the following steps:
And transmitting the service information corresponding to the user access request cached by the VCDN edge service node or the CDN edge service node to a user side.
It should be noted that the edge subsystem includes several VCDN edge service nodes and CDN edge service nodes.
When a user terminal initiates a user access request, the user access request is generally sent to a CDN edge service node with the shortest route with the user terminal, and then the CDN edge service node sends the user access request to a portal management and control subsystem.
After determining the edge service node corresponding to the user access request, if the edge service node caches the service information corresponding to the user access request, directly returning the service information to the user side; if the edge service node does not cache the service information corresponding to the user access request, the edge service node initiates a request for the service information corresponding to the user access request to an IP address in domain name configuration information, and after the service information corresponding to the user access request is obtained, the service information corresponding to the user access request is cached to the edge service node by combining with a caching strategy configured by a technician in a self-defining manner and returned to the user side.
It should be noted that, in this embodiment, the edge subsystem actively acquires the VCDN edge service node or CDN edge service node corresponding to the user access request determined by the operation and maintenance subsystem. Thus, independence of the subsystems is better achieved.
The embodiment of the application also provides a service distribution method based on the hybrid management system, which is applied to the scheduling subsystem.
In this embodiment, the service distribution method includes the following steps:
Generating a scheduling queue containing VCDN edge service nodes and CDN edge service nodes or generating a scheduling queue containing CDN edge service nodes according to the characteristic attribute of the VCDN of the area where the user terminal is located and the node information of each edge service node in the edge subsystem, so that the operation and maintenance subsystem can determine the corresponding VCDN edge service node or CDN edge service node of the user access request from the scheduling queue containing the VCDN edge service nodes and the CDN edge service nodes or the scheduling queue containing the CDN edge service nodes according to the configuration information.
According to the characteristic attribute of the VCDN of the area where the user terminal is located and the node information of each edge service node in the edge subsystem, a scheduling queue including the VCDN edge service node and the CDN edge service node is generated, or a scheduling queue including the CDN edge service node is generated, which specifically includes:
When the VCDN of the area where the user is located is in an enabling state, adding a VCDN edge service node and a CDN edge service node which have the load capacity larger than the preset load capacity and the routing distance smaller than the preset routing distance with the user terminal in the edge subsystem into a scheduling queue;
When the VCDN of the area where the user is located is in a deactivated state, adding CDN edge service nodes with the load capacity larger than the preset load capacity and the routing distance smaller than the preset routing distance with the user end in the edge subsystem into a scheduling queue.
The preset loading capacity and the preset routing distance may be customized by a technician, and are not particularly limited in this embodiment.
