After obtaining the stroke data, the first client selects a target protocol, and sends the stroke data to a server through the target protocol so that other second clients can obtain the stroke data from the server. One of the target protocols is a Control (Control) type and one of the Data (Data) types. The control type protocol is mainly used for being related to an auxiliary control type protocol of the whiteboard data type, the data type protocol is mainly related to the whiteboard data protocol, the control type protocol is not required to be adapted to the resolution, and the data type protocol is required to be adapted to the resolution.

after authentication verification, the first client receives an initialization protocol sent by the server, analyzes all whiteboard page IDs in the initialization protocol, and sends a page request protocol to the server based on all whiteboard page IDs;
and receiving a page response protocol based on the page request protocol returned by the server, and analyzing the page response protocol and performing UI rendering by the first client to obtain a target whiteboard page.
3. The method for synchronizing electronic whiteboard data according to claim 1, wherein the step of the first client selecting a target protocol, sending the stroke data to a server through the target protocol, so that other second clients can obtain the stroke data from the server includes:
the first client side obtains an operation type corresponding to the stroke data;
the first client selects the target protocol according to the operation type;
and sending the stroke data to a server through the target protocol so that other second clients can obtain the stroke data from the server.
4. The method for synchronizing electronic whiteboard data according to claim 1, wherein the step of the first client selecting a target protocol, sending the stroke data to a server via the target protocol, so that other second clients can obtain the stroke data from the server, comprises:
and if the first client side is detected to edit the stroke data, carrying out synchronous processing on the edited stroke data.
5. The method for synchronizing electronic whiteboard data according to claim 1, wherein the step of the first client selecting a target protocol, sending the stroke data to a server via the target protocol, so that other second clients can obtain the stroke data from the server, comprises:
and if the synchronous instruction is detected to be closed, closing the communication connection between the first client and the server.
6. An electronic whiteboard data synchronizing device, characterized in that the electronic whiteboard data synchronizing device comprises:
the detection module is used for extracting stroke data based on a synchronization instruction when the first client side detects the synchronization instruction on the electronic whiteboard;
and the sending module is used for selecting a target protocol by the first client and sending the stroke data to a server through the target protocol so as to enable other second clients to obtain the stroke data from the server.
7. An electronic whiteboard data synchronization apparatus, characterized in that the apparatus comprises: memory, a processor and an electronic whiteboard data synchronization program stored on the memory and executable on the processor, the electronic whiteboard data synchronization program when executed by the processor implementing the steps of the electronic whiteboard data synchronization method according to any of claims 1 to 5.
8. A medium having stored thereon an electronic whiteboard data synchronization program, which when executed by a processor implements the steps of the electronic whiteboard data synchronization method according to any one of claims 1 to 5.
