For example: the service model is provided with user data which provides the service capability of a newly added user, the service capability of a deleted user or the service capability of a modified user, and the like, and the data structure of the model is self-defined. The access request carries a user identifier, a model name, a service capability name and a service parameter, the user identifier represents the identity of a user initiating the access request, the model name represents the name of the called target model, the service capability name represents the name of a class object included in the called target model, and the service parameter represents a field and an attribute value transmitted to the class object. The format of the access request may be a URL (Uniform Resource Locator).

For example: when a service capability of a newly added user is requested to the model, an access request is expressed as { vipAddress }/sv/model/system _ user/savetReturn, and service parameters carried by the access request are expressed as: { "username": Zhang III "," gid ": afadccdc525856522060f9b9c9362a3 b", "sex": 1 }; wherein, system _ user represents the model name, and saverturn represents the business capability name.

In one or more possible embodiments, before S201, the computer device creates a model and adds the created model to the model set, and the creating may be:

The method and the device call the class object indicated by the service capability name when the class object is in the running state. For example: according to the example in S201, the determined class objects are bizentitylmodel manager and saverturn, and the fields and attribute values included in the service parameters are introduced into the class objects.

And S204, returning a calling result obtained by the class object responding to the service parameter to the user indicated by the user identifier.

The class object acquires the service parameters in the running state, obtains a calling result based on the service parameters, and then returns the calling result to the caller. Optionally, each model in the model set may be deployed in a distributed cache to improve the response speed of the model.
