Rather, embodiments of the present invention may be applied to any scenario where applicable.
The invention will be further explained by the description of the embodiments with reference to the drawings.
As shown in fig. 2, the present embodiment provides a data transmission method, where a main body executing the method in a data transmission system is a service terminal, and the data transmission method includes the following steps:
and S10, establishing connection with the client terminal based on the preset websocket server and the http server.
Specifically, a websocket server and an http server are installed in advance for the service terminal. Based on the websocket protocol, an unlimited bidirectional protocol is established between the service terminal and the client terminal to realize data transmission. Based on the http server, the service terminal and the client terminal are connected in a unidirectional data transmission manner. The http server can only respond when it needs to receive a request sent by the client terminal.
In a first implementation manner of this embodiment, the websocket server and the http server are packaged in separate application programs.
In a second implementation manner of this embodiment, as shown in fig. 3, the websocket server and the http server are stored in an installation package of an application program in the form of a plug-in file, such as AE. AE provides a number of open plug-in interfaces based on which plug-ins with some functionality can be designed. The http server and the websocket server are stored in the program file of the AE in the form of plug-in files. When the AE is started, the program file is scanned, and the http server and the websocket server are obtained and installed.
The client terminal comprises a first connection module, and after the websocket server and the http server are installed, the first connection module can be connected with the service terminal through a protocol, wherein the connection comprises websocket connection and http connection.
http connects as long as through three times handshake can realize, and to the websocket connection needs more detailed information, for the convenience client terminal and the quick convenient connection of establishing of service terminal to and the secret nature of connection, in this embodiment, the process of establishing the websocket connection includes:
a10, when the websocket server is detected, generating connection information corresponding to the websocket server based on preset basic information.
Specifically, when the websocket server is installed and the service terminal detects the websocket server, the corresponding connection information is automatically generated. The service terminal itself stores connection parameters related to the local server and the websocket server, such as IP address and port information. And converting the connection parameter information into connection information.
And A20, sending the connection information to the client terminal.
Specifically, the connection information is then transmitted to the client terminal. In the first transmission mode, the connection information may be transmitted to the client terminal based on a local area network, bluetooth, or the like. In a second transmission mode, the connection parameters are converted into a two-dimensional code image, and the two-dimensional code image is displayed as connection information.
A30, when detecting the connection request sent by the client terminal based on the connection information, establishing connection with the client terminal based on the websocket server.
Specifically, the first connection module of the client terminal includes a photographing unit, an analyzing unit, and a first connection unit. The client terminal is provided with a camera, and the photographing unit can control the camera to photograph the two-dimension code image to obtain the two-dimension code information. And then the analyzing unit analyzes the two-dimension code information to obtain a connection parameter for realizing the connection with the websocket server. And finally, based on the connection parameters, the first connection unit sends a connection request to the websocket server, and meanwhile, the connection parameters are stored locally as historical parameters.
And when detecting a connection request sent by the client terminal based on the connection information, the websocket server responds to the connection request to establish websocket connection between the service terminal and the client terminal.
Further, after the websocket connection is established, since the communication between the service terminal and the client terminal depends on the stability of the websocket connection, if data transmission is not needed for a while, the websocket service maintains the connection with the client terminal for a long time, which also results in resource waste. Therefore, in this embodiment, the websocket server also adopts a heartbeat mechanism to avoid waste of resources during the connection process to the client terminal. The process is as follows:
and B10, acquiring the terminal information of the client terminal, and recording the terminal information in a preset mass sending list.
Specifically, a mass texting list is set in advance, and terminal information of each client terminal connected to the websocket server is recorded in the mass texting list. Whenever the websocket server establishes a websocket connection with a client terminal, the websocket server requests terminal information of the client terminal from the newly connected client terminal. The terminal information is information having an identification function such as an IP address of the client terminal. And recording the terminal information in a mass sending list every time one terminal information is obtained.
B20, based on the websocket server, sending ping signaling to the client terminal corresponding to the mass sending list.
Specifically, an access interval is preset, and ping signaling is continuously sent to the client terminal through the websocket server.
And B30, for each client terminal, determining that the client terminal is available when the pong signaling sent by the client terminal according to the ping signaling is detected according to the preset detection time.
Specifically, the client terminal includes a heartbeat module, and taking a single client terminal as an example, after sending the ping signaling to the client terminal based on the group sending list, if the heartbeat module is running, the heartbeat module feeds back the pong signaling to the service terminal based on the ping signaling; and if the heartbeat module stops running, the heartbeat module cannot feed back the pong signaling.
A detection time is set for each client terminal in advance, and all the client terminals can adopt the same detection time or carry out different detection times according to the frequency used by the client terminals. And aiming at the latter, calculating the use frequency of each client terminal according to the terminal information and the use time, and determining the detection time corresponding to each client terminal according to the use frequency. The higher the frequency of use, the longer the detection time.
And after sending the ping signaling, the service terminal waits for the pong signaling fed back by the client terminal based on the detection time. When the pong signaling sent by the client terminal according to the ping signaling is detected according to the detection time, it indicates that the heartbeat module of the client terminal is still running and needs to continue to send data stably, thus determining that the client terminal is available.
B40, when the ping signaling is not detected according to the detection time, deleting the terminal information corresponding to the client terminal in the group sending list.
Specifically, when the ping signaling fed back by the client terminal is not detected according to the detection time, it indicates that the client terminal temporarily does not need to transmit data, so that the client terminal is determined to be unavailable, and the terminal information corresponding to the client terminal in the mass texting list can be deleted. The subsequent service terminal no longer needs to send ping signaling to the client terminal based on the websocket server.
And S20, performing event monitoring on the preset monitored object.
Specifically, the monitored object to be monitored by the service terminal is preset. And after the websocket server and the http server are installed, performing event monitoring on the monitored object. Event monitoring is mainly used for monitoring whether changes of files, such as file updating and file adding, occur.
The embodiment exemplifies a specific process with two types of listening objects. The first monitoring object is a memory, the memory comprises a disk, a hard disk and the like, and the http server provides two interfaces, one is an interface of a file list of the memory, and the file list is composed of information of all files in the memory; one is the interface of all files of the memory. For a memory as a snooping object, the event snooping can directly adopt file snooping, for example, based on a webpack open snoop mode. Based on two interfaces provided by the http server, webpack can poll to determine whether the last editing time of each file changes. For each file, if the last editing time of the file changes, marking the file, and judging whether the file changes in the waiting time based on the preset waiting time. If the file is changed, the changed file is used as an update file; and if the file is not changed, taking the unchanged file as an updated file. Wherein, the waiting time can be freely set, and is recommended to be set to be 200-300 ms. In addition, if a new file exists, that is, the last editing time of the file is after the last polling, the file is also an updated file. In addition, inotify can be adopted for file monitoring. The file can be prevented from being monitored and transmitted in the storage and modification processes, and the accuracy is prevented from being influenced.
Furthermore, as the intermediate cache file is generated in the processes of generating, modifying and the like of partial files, and the format of the intermediate cache file is different from that of the complete file, a screening rule can be preset, and the files in the memory are selectively monitored based on the screening rule. For example, only files in docx, which is the file format, are monitored, while files in other formats are not monitored, and changes in other files are not transmitted to the client terminal.
The second type of interception object is an application, and as in the second implementation, is installed in an application AE, and the interception object is the AE. For the listening application, the generation of the file needs to be realized by function keys such as "save", "save as" and "export", and in this embodiment, events caused by operating these function keys are collectively referred to as export events. These derived events are snooped in advance. As shown in fig. 4, the created clip template is saved locally by the "export" button. When the 'export' key is clicked and the file export exists, the target event can be determined to have occurred. And subsequently, taking the file corresponding to the export event as an update file.
And S30, when the target event corresponding to the monitored object is monitored, generating http information of the update file corresponding to the monitored object according to the target event.
Specifically, the target event that the service terminal desires to monitor, that is, the aforementioned event causing the file change, is set in advance. If the server terminal monitors that the file changes, the changed file needs to be transmitted to the client terminal. For example, a back-end engineer creates a file with different rendering effects by using AE, when the file is stored locally in the service terminal, the service terminal can monitor that an event of a newly added file occurs, and simultaneously, the monitored target event includes the position of the event besides the nature of the event, for example, the file of the newly added file is stored in a C disk. And the service terminal takes the changed file as an update file and generates http information corresponding to the target event according to the target event. Taking the newly added file stored in the C disk as an example, http information of the updated file is generated according to the storage address of the newly added file and the file information of the newly added file.
In the first generation mode, the storage address of the update file and the update file are directly integrated to generate an http address which can be used for data requests. The http address is directly used as http information.
In the second generation mode, in order to better determine the file which needs to be downloaded by the subsequent user in the client terminal, the file information includes information such as the file name, the generation time, and the file type of the newly added file. And packaging the http address and the file information to generate http information.
And S40, sending the http information to the client terminal based on the websocket server.
Specifically, after the http information is obtained, the http information needs to be sent to the client terminal. The websocket server has a bidirectional transmission function, http only can respond passively, and therefore the obtained http information is sent to the websocket server, and then the websocket server is connected with the client terminal through the websocket, and the http information is sent to the client terminal.
And S50, when a downloading request sent by the client terminal according to the http information is detected, sending the update file to the client terminal based on the http server.
Specifically, the client terminal further comprises a processing module and a request module, and when the http information is sent based on websocket connection, the http information is subjected to information extraction, and description of the updated file, namely file information such as a file name, generation time and a file type, is extracted. After the processing module extracts the obtained file information, the file information is displayed on the display screen, as shown in fig. 5, where the displayed file information includes a file name, update time, a file format, and the like.
After the file information is displayed, the user judges whether the file needs to be downloaded. If downloading is required, the user sends a first confirmation instruction to the client terminal through an input device, such as a key or a touch pad. And when a first confirmation instruction sent by the user aiming at the file information is detected, the request module sends a downloading request to the service terminal according to the http address in the http information. The http protocol is a request-response mode, when a download request sent by the client terminal according to http information is detected, the http server can initiate a response, and the http server has a function of requesting a disk to specify a file, so that based on the http address and the http server, the service terminal can send an update file corresponding to the download request to the client terminal.
In the whole process, the webococket server is used for sending short data and has a bidirectional transmission function, so that the information of file change of the service terminal can be quickly and effectively transmitted to the client terminal. If the client terminal needs downloading, the downloading is directly carried out through the http protocol, and the http protocol can support the transmission of large files, so that the files processed by the service terminal are stably and efficiently transmitted to the client terminal. In the process, the service terminal is in an active transmission status, the user does not need to manually select the uploaded object, and the user can obtain the change of the service terminal in real time at the client terminal and can pass through the change
