Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings. It is only noted that the invention is intended to be limited to the specific forms set forth herein, including any reference to the drawings, as well as any other specific forms of embodiments of the invention.
FIG. 1 is a general flowchart of the classroom interaction cross-platform synchronization method of the present invention, including:
s101, establishing a first connection channel between the server and the fixed terminal, and generating an encrypted connection identifier.
And S102, establishing a second connection channel between the server and the mobile terminal according to the encrypted connection identifier.
S103, acquiring a first operation instruction sent by the mobile terminal through the second connecting channel.
And S104, judging whether the sending terminal of the first operation instruction is of a first preset type.
And S105, if the operation instruction is judged to be yes, executing the first operation instruction, and forwarding the first operation instruction to the fixed terminal through the first connecting channel so as to drive the fixed terminal to perform synchronous operation according to the first operation instruction.
S106, acquiring a second operation instruction sent by the fixed terminal for synchronous operation through the first connecting channel;
and S107, judging whether the sending terminal of the second operation instruction is of a second preset type.
And S108, judging that the second operation instruction is not executed and is not forwarded if the judgment result is yes.
