The first embodiment is as follows:
as shown in fig. 1-3, a distributed KVM agent collaboration graph pushing method includes the following steps:
s1: acquiring an instruction sent by the outside, and establishing connection with a background server to acquire information of all users;
specifically, after the KVM seat output module is started, a connection needs to be established with the background server to obtain information of all users, where the information of the users refers to information of user names, user numbers, and the like recorded by the server, and after the KVM seat output module is connected with the background server, the background server sends information of all the users to the KVM seat output module to update the user list interface of the control panel, in this embodiment, S1 is specifically implemented by the following steps:
s11: acquiring a starting instruction sent by the outside;
specifically, the user sends a start instruction to the KVM agent output module, and in this embodiment, the KVM agent output module starts to operate normally by pressing a power key or starting by other means.
S12: initiating internal authentication;
specifically, a software control module is further installed inside the KVM seat output module, and the software control module is linked with the KVM seat output module through power on. In this embodiment, the internal authentication is specifically implemented as follows:
acquiring a first certificate sent by a software control module;
specifically, the software control module initiates a handshake request to the KVM agent output module and starts to send the first authentication information to the KVM agent output module.
Sending the first authentication information and the second authentication information stored in the storage to the software control module;
specifically, after obtaining the first authentication information sent by the software control module, the KVM agent output module feeds back the second authentication information and the first authentication information, which are generated in advance and stored in the storage, to the software control module.
Acquiring second authentication information sent by the software control module;
specifically, after the software control module obtains the first authentication information and the second authentication information, the software control module verifies the first authentication information first, if the first authentication information passes the verification, the second authentication information is fed back to the KVM agent output module, and if the second authentication information does not pass the verification, the authentication is restarted.
And judging whether the second authentication information sent by the software control module is the same as the second authentication information in the memory, if so, finishing the authentication, establishing the connection, and executing S13, otherwise, executing S121 again.
Specifically, after the KVM agent output module obtains the second authentication information, the KVM agent output module verifies the second authentication information, compares the obtained second authentication information with the second authentication information in the storage, determines that the authentication of the KVM agent output module and the software control module is completed if the obtained second authentication information and the second authentication information in the storage are consistent, establishes a connection between the KVM agent output module and the software control module, and restarts the authentication if the obtained second authentication information and the obtained second authentication information are not consistent until the authentication is passed and the connection can be established.
Further, when the second authentication information obtained by the KVM agent output module does not match the second authentication information in the storage, the timer is triggered to limit that the KVM agent output module and the software control module cannot perform authentication within a predetermined time (for example, 5 seconds, ten seconds, or one minute), and after the timer finishes timing, the KVM agent output module and the software control module restart authentication, so that specific brute force cracking is avoided.

specifically, after the internal authentication of the KVM agent output module is completed, the TCP connection is performed between the KVM agent output module and the server through the WebSocket frame by using the background server IP address, so as to meet the requirement of real-time updating of the layout change of the graphical screen.
S14: judging whether the connection with the background server is successful, if not, executing S13, if so, sending a request for acquiring information of all users to the background server, and executing S15;
specifically, if the connection between the KVM agent output module and the backend server fails, the connection is reconnected until the connection is successful, and after the connection is successful, the KVM agent output module sends a request for acquiring information of all users to the backend server to acquire the information of all users.
S15: and acquiring information of all users, updating a user list interface of the control panel by analyzing the information of all users, and hiding the finished control panel.
Specifically, after the background server acquires the request for acquiring the information of all the users, which is sent by the KVM seat output module, the information of all the users is sent to the KVM seat output module, so that the KVM seat output module acquires the information of all the users, analyzes the information, and updates the data obtained by analysis to the user list interface of the control panel, so far, the KVM seat output module completes the initial loading of the user information, and basically updates the layout change of the existing graphical screen to the control panel, so that the subsequent scheduling and pushing are more accurate and effective, the working efficiency of the users is improved, and then the control panel can be hidden.

specifically, the scene and the plan are both set by the user on the control panel according to the self condition, the list of the KVM agent input modules is a summary table of links of each KVM agent input module, the list of the screens is a summary table of links of each screen, and further, the list of the screens may also be a summary table of links of each sub-screen spliced into a screen. After the KVM seat output module is connected to the backend server, the control panel initially completes loading of basic information of all users, but each user has personalized information, and the control panel can enable the personalized information to be displayed on the control panel only after obtaining user personalized data, and after the user logs in, the KVM seat output module can send a request for obtaining the user personalized data to the backend server, in this embodiment, S2 is specifically implemented by the following steps:
s21: acquiring a control panel display instruction sent by the outside, and sending a user login prompt to the outside;
specifically, since the control panel is automatically hidden after the user list is updated, the user needs to display the control panel before logging in, in this embodiment, the S21 is specifically implemented by the following steps:

specifically, the user sends the control panel display instruction to the KVM seat output module through the keyboard or the mouse, for example, the user presses down the display shortcut Ctrl or a through the keyboard, so that the KVM seat output module obtains the control panel display instruction, and then displays the control panel.
S212: accumulating the times of the control panel display instructions continuously sent from the outside and storing the times to a storage;
specifically, in order to avoid the situation that the control panel is displayed due to the fact that the keyboard or the mouse is pressed by mistake, when a user presses a display shortcut key for the first time, the KVM seat output module already captures a control panel display instruction, and starts to accumulate the times of continuously capturing the control panel display instruction; further, when the KVM seat output module starts capturing the control panel display instruction, the timer is started, if the time for continuously capturing the control panel display instruction is less than a preset first time (e.g., 1 second), the control panel display instruction is not counted in the accumulated times, and if the time for continuously capturing the control panel display instruction is greater than a preset second time (e.g., 10 seconds), the control panel display instruction is also not counted in the accumulated times.
S213: and judging whether the frequency of the control panel display instructions continuously sent by the outside is equal to a preset value, if so, displaying the control panel, sending a user login prompt to the outside, and if not, executing S211.
Specifically, when the KVM seat output module starts to capture a control panel display instruction, it is synchronously determined whether the number of times of continuously capturing the control panel display instruction is equal to a preset value (for example, the preset value is equal to 3), and then the user needs to send the control panel display instruction to the KVM seat output module through a keyboard or a mouse for 3 times, so that the control panel is displayed on a display corresponding to the KVM seat output module, and meanwhile, the control panel pops up a user login box to prompt the user to log in, so as to obtain personalized data.
S22: acquiring user login information sent by the outside, and sending the user login information to a background server for verification;
specifically, a user inputs user login information in a user login box through a keyboard or a mouse, and then the KVM seat output module sends the user login information to the background server for verification.
S23: the background server checks whether the user login information is correct or not, if not, the background server sends information of checking failure to the KVM seat output module and executes S22, and if so, the background server sends information of checking passing to the KVM seat output module and executes S24;
specifically, the background server checks the user login information after obtaining the user login information, prompts the user to input the user login information again if the user login information does not pass the check, and sends check passing information to the KVM seat output module if the user login information passes the check, so that the KVM seat output module actively requests the background server for the personalized data of the user, and the personalized information of the user is displayed on the control panel.
S24: and sending a request for acquiring the user personalized data to a background server, so that the background server circularly judges each piece of data in the storage according to the authority of the currently logged-in user, judges whether the user has the authority of the current data, if so, adds the current data into a linked list of the user personalized data, circularly judges the next piece of data, and if not, circularly judges the next piece of data.
Specifically, after the KVM agent output module obtains the information that passes the verification, it indicates that the current user successfully logs in, and at the same time, the KVM agent output module sends a request for obtaining the user personalized data to the background server to request the background server to send the user personalized data, and after the KVM agent output module obtains the information that passes the verification of the user login information, it actively sends a request for obtaining the user personalized data to the background server, so that the background server starts to screen the user personalized data in the storage, thereby screening the user personalized data associated with the current user, and according to the request for obtaining the user personalized data, according to the authority of the currently logged-in user, it performs a cyclic judgment on each piece of data in the storage to judge whether the user has the authority of the current data, if so, it adds the current data into the linked list of the user personalized data, and continuously and circularly judging the next piece of data, if not, indicating that the user has no authority to use the current data, and continuously and circularly judging the next piece of data.
