and S120, if so, the browser sends an update request for the first http port to the local server in a Websocket mode, so that the local server updates the port for establishing communication between the browser and the local server to a second http port based on the update request.
In this embodiment of the application, the first http port may be a communication interface pre-established between the browser end and the local service end in a local http manner.
In the embodiment of the application, when the browser end establishes communication with the local server end through the first http port, the browser end may poll each first http port in sequence, and if it is determined that the communication condition of each first http port satisfies the preset reconnection condition, it may be considered that the communication between the browser end and the local server end cannot be established through the first http port.

The browser end can poll each first http port in sequence to initiate a communication request, and meanwhile, the local server end can monitor the communication request and return a communication establishment result to the browser end.
If the communication request is failed to be established or the communication request is over time for T seconds (that is, a preset reconnection condition is met), the N ports (that is, the second http port) may be updated to perform the next round of communication, specifically, after it is determined that the browser supports the communication mode of the Websocket, the N port information (that is, the port information of the second http port) may be negotiated through the communication mode of the Websocket, and the local server may update the second http port.
