Invoking device services in preset software frameworks

A method for invoking a service, comprising:

• generating, by a first device service in a preset software framework, service invocation request information in response to detecting that current environment meets a condition of invoking a second device service in the preset software framework, wherein the preset software framework is applicable to a gateway device, the preset software framework comprises a plurality of device services registered in advance, and each of the plurality of device services corresponds to a capability of a device associated with the gateway device in the current environment;
• sending, by the first device service, the service invocation request information to the second device service based on a data bus preset in the preset software framework;
• and
• receiving, by the first device service, service invocation response information sent by a second gateway service based on the data bus, wherein the service invocation response information comprises information generated based on an obtained processing result after the second device service performs processing on the service invocation request information that is received;
• wherein generating the service invocation request information in response to detecting that the current environment meets the condition of invoking the second device service in the preset software framework comprises:
• generating the service invocation request information based on a service query result obtained in advance, in response to detecting that the current environment meets the condition of invoking the second device service in the preset software framework, wherein the service query result comprises a result obtained by querying a service in the preset software framework in advance.
