Data acquisition method, system and device, server and storage medium

The invention relates to a data acquisition method, system and device, a server and a storage medium. The method comprises the following steps: in response to a data acquisition request of a target application service for target data, detecting whether target data is stored in a single local cache deployed for a server in advance; deploying at least two application services in the server, wherein the at least two application services comprise a target application service, the local cache is used for providing data caching service for at least two application services; and under the condition that the target data is stored in the local cache, obtaining the target data from the local cache, and returning the obtained target data to the target application service. According to the method and the device, a single local cache is set for the server deployed with a plurality of application services, and the local cache service can be provided for the plurality of application services, so that the same cache data can
