The application discloses a
data synchronization method, device and equipment and medium, the
data synchronization method comprises the following steps: when a service request is initiated to a
server, first starting a
delay message, and then sending the service request to the
server; after starting a
message queue, querying the service state of the service request according to the
message queue; determining whether the data is synchronized with the
server according to the service state; if not, performing a corresponding synchronization operation. According to the application, when a service request is initiated to a server, a
delay message is first started, and after a
specific time delay, the
client can actively query whether the data is synchronized with the server according to the
message queue, and perform a corresponding synchronization operation according to the service state, so that the data inconsistency caused by a long communication exception interval can be automatically processed, the
client actively performs a synchronization operation to achieve
data consistency, and the needs of the
client can be more effectively met, and the stability and practicability of
data transmission are improved.
