The invention discloses a method for
copying and pasting among cloud application programs of a plurality of cross-
cloud server host sessions. The method comprises the following steps: S1, setting a
clipboard proxy program on each
cloud server host; S2, creating a subscription
queue on a
message queue server; S3, enabling the
clipboard agent program in the session A to broadcast the copy operationinformation, and enabling other cloud
clipboard agent to program set respective
system clipboard by using
declaration; and S4, executing a pasting operation on the session B by the user, and putting the obtained clipboard data into a
system clipboard of the
cloud server host for a window initiating a pasting behavior to obtain. According to the clipboard grouping and sharing technology, the same user can be connected to a plurality of cloud
server hosts at the same time, cloud application windows running on a plurality of remote hosts are opened and used concurrently, user-level clipboard
copying and pasting operation is carried out on the cloud application windows crossing the cloud
server hosts, the speed is high, and secret divulging is prevented.
