Fig. 1 shows a schematic flowchart of an update method for a data port provided in an embodiment of the present application, and as shown in fig. 1, the method mainly includes:
step S110, when the browser establishes communication with a local server through a first http port, determining whether the communication condition of the first http port meets a preset reconnection condition;
and step S120, if the request is met, the browser sends an updating request for the first http port to the local server in a Urlscheme mode, so that the local server updates the port for establishing the communication between the browser and the local server to a second http port based on the updating 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.
In practical use, the reconnection condition may include that all the first http ports fail to establish communication, or that all the first http ports fail to establish communication within a preset time period.
The number of the ports of the first http port and the preset duration are selected to take user experience into consideration, the number of the ports of the first http port is suggested to be 5-10, and the value of the preset duration is less than 2 seconds.
In the embodiment of the application, when the communication condition of each first http port meets the preset reconnection condition, the communication ports may be allocated again in an Urlscheme communication manner, specifically, the browser may send an update request for the first http port to the local server in the Urlscheme manner, and the local server updates the port for establishing the communication between the browser and the local server to the second http port based on the update request.
According to the method provided by the embodiment of the application, when the browser end establishes communication with the local server end through the first http port, if the communication condition of the first http port meets the preset reconnection condition, the browser end sends an update request for the first http port to the local server end in a Urlscheme mode, so that the local server end updates a port for establishing communication between the browser end and the local server end to the second http port based on the update request. Based on the scheme, when the communication between the browser end and the local server end cannot be established through the first http port, the communication port is distributed again in the Urlscheme communication mode, the first http port is updated, and a foundation is provided for establishing normal communication between the browser end and the local server end through the updated communication port.
In an optional manner of the embodiment of the present application, the method further includes:
and the browser end establishes communication with the local server end through the second http port.
In the embodiment of the application, the browser terminal can retry to establish communication with the local server terminal through the updated second http port.
Specifically, the browser side may poll each of the second http ports in turn.
In an optional manner of the embodiment of the present application, when the communication with the local server is established through the second http port, if the communication condition of the second http port satisfies the reconnection condition, the method further includes:
and taking the second http port as a first http port, repeatedly executing the browser to send an update request to the first http port to the local server in an Urlscheme manner, so that the local server updates a port for establishing communication between the browser and the local server to the second http port based on the update request, and the browser establishes communication with the local server through the second http port until a preset stop condition is met.
In this embodiment of the application, if it is determined that the communication condition of each second http port satisfies the preset reconnection condition, it may be determined that the communication between the browser side and the local server side cannot be established through the second http port, and the first http port may be used to repeatedly execute the operation of updating the communication port in the manner of Urlscheme until the preset stop condition is reached.
The communication between the browser end and the local service end is established through the updated communication port, and the success rate of establishing communication between the browser end and the local service end can be improved. In practical use, in order to avoid that a lot of time is occupied by updating the communication port for many times and establishing communication by using the updated communication port, and a long-time waiting for a user is caused, a stop condition can be preset to finish the process of establishing communication.
In an optional manner of the embodiment of the present application, the stop condition may include: the repeated execution times reach the preset times.
In the embodiment of the application, the maximum repeated execution times can be preset, when the repeated execution times reach the preset times, the repeated execution is not continued, and a prompt message for communication establishment failure is sent to a user.
In an optional manner of the embodiment of the application, the local server updates a port for establishing communication between the browser and the local server to the second http port based on the update request, and the method includes:
and the local server updates the port for establishing the communication between the browser terminal and the local server terminal into the second http port based on the port information of the second http port carried by the update request.
In the embodiment of the application, the browser end can determine the port information of the second http port and send the update request based on the port information of the second http port, and the local server end can update the port for establishing communication between the browser end and the local server end to the second http port.
In an optional manner of the embodiment of the present application, the sending, by the browser end, an update request for the first http port to the local server end in a manner of Urlscheme includes:
determining whether the current operating system supports Urlscheme;
if the first http port is supported, the browser end sends an update request of the first http port to the local server end in a Urlscheme manner
In the embodiment of the application, before the communication port is updated, whether the current operating system of the device supports the Urlscheme communication mode or not can be determined, and if so, the communication port can be updated; if not, the process of establishing communication can be stopped.
Fig. 2 shows a flowchart of a specific implementation manner provided by an embodiment of the present application, and as shown in fig. 2, a browser end may set initial information such as a port (i.e., a first http port) and a maximum timeout T seconds (i.e., a preset duration) in a local http manner in advance.
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) can be updated to perform the next round of communication, specifically, N port information (that is, port information of the second http port) is negotiated through a communication mode of the Urlscheme, and the local server can update the second http port. And then, waiting for the local server to try to establish communication through the second http port, if a reconnection condition is met, retrying the operation step for updating the communication port until the retrying time is greater than C times (namely greater than a preset time), ending the process, and sending a prompt message of communication establishment failure to the user.
