Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a schematic diagram of a main flow of a method for remote server management according to an embodiment of the present invention, as shown in fig. 1, the method for remote server management includes the following steps:

step S101: responding to a received login request sent by a foreground, and establishing session connection between the foreground and a target remote server; the login information and the target remote server are indicated in the login request;

step S102: receiving login data corresponding to the login information returned by the target remote server;

step S103: and converting the login data into a data stream, carrying out coding processing on the data stream according to the coding configuration of the foreground, and sending the coded data stream to the foreground so as to enable the foreground to display the coded data stream.

In the embodiment of the present invention, in step S101, a login request sent by a foreground is received, where the login request indicates login information and a target remote server, and the login information includes at least one of a login account, a login password, and the like.

In the embodiment of the present invention, the foreground may be a browser terminal, such as a web browser terminal, and the background may be a server corresponding to the foreground.

Optionally, before receiving the login request sent by the foreground, the foreground receives a selection instruction of the target remote server from the remote server list to determine the remote server. The method comprises the steps that a user configures query conditions according to needs, a remote server list is obtained according to the query conditions, then one or more remote servers are selected from the remote server list, and a selection instruction is sent to a background, so that the background takes the one or more remote servers selected by a foreground as target remote servers.

Optionally, establishing a session connection with the foreground and the target remote server includes: checking the login request, and establishing socket connection with a foreground after the check is passed; and matching the target remote server according to the login request, and establishing remote connection with the target remote server. The foreground and the background establish socket connection, namely websocket connection, so that the foreground and the background establish long connection, send and receive data through the socket connection, and a customized interface can be manufactured according to message content. The remote connection may be a ssh connection, an rdp connection, an rsh connection, etc. The background establishes ssh connection with the target remote server, and sends and receives data through the ssh connection, so that the background can access the target remote server through an ssh protocol, the connection is persistent, and the session connection between the foreground and the target remote server is established.

Optionally, after the socket connection with the foreground is established, the heartbeat detection is timed, that is, the connection state between the background and the foreground is detected regularly, and the validity of the session is detected.

In one embodiment, matching a target remote server according to a login request to establish a remote ssh connection with the target remote server comprises: and obtaining ssh connection with the target remote server according to the login request by adopting an Open-ssh technology.

The ssh is a security protocol created on the basis of an application layer and a transport layer, and provides a traditional network service program of a secure transmission and use environment for the shell of the computer, the ssh connection is based on the ssh protocol, the rdp connection is based on the rdp protocol, and the rsh connection is based on the rsh protocol.

In the embodiment of the invention, the login request is verified, including the login information. The login information comprises a login account, the login account can be verified, whether the login account has the authority of logging in the target remote server or not is judged, and if yes, the verification is passed. Before the login information is verified, a login account list with the authority of logging in the target remote server is configured in advance, and if a login request, namely a login account included in the login information, is in the login account list, the corresponding target remote server can be logged in. For example, a common account list and an administrator account list can be configured in advance, so that the login authority of a login account on a target remote server can be judged, the authority isolation of different user management servers in a test environment is realized, and the management authority of different users on the server is limited.

The target remote server which needs to be authorized may exist in the target remote server, and the authorization code needs to be verified aiming at the target remote server which needs to be authorized, so that the target remote server which does not need to be authorized does not need to be verified by the authorization code. Optionally, the login request further includes an authorization code for the target remote server, the verification of the login request includes the verification of the authorization code, and if the authorization code for the target remote server in the login request is the same as the configured authorization code for the target remote server, the verification passes. The user logs in the target remote server through the authorization code and checks the authorization code to configure the access strategy, so that the management authority of the user on different servers can be limited, the management flexibility is high, the working efficiency can be improved, and the management capability of system services can be improved.

Optionally, after the login information and/or the authorization code in the login request is verified and the verification is passed, the login information and/or the authorization code, the stored login authentication information of the target remote server, the server password and other information are sent to the target remote server to match the target remote server, so that the remote connection with the target remote server is realized. Sensitive information such as login authentication information and server passwords of a target remote server does not need to be input by a foreground, login management is carried out by a background, so that a user has the authority of managing the target remote server in the current session process without knowing the server passwords, the sensitive information of the server cannot be leaked when the user carries out remote server management in public equipment, and safety risks are reduced. The user can obtain the control right of the operation session of the user with the authority on the premise of not mastering the sensitive information.

After session connection is established between the remote server and the foreground, login data corresponding to login information returned by the target remote server are received and returned to the foreground, and the login data are converted or packaged into a data stream (stream) when returned to the foreground, so that sessions are exchanged in a data stream mode, the number of times of sensitive information interaction is reduced, and sensitive information leakage can be effectively avoided. And then, acquiring the coding configuration of the foreground through socket connection, coding the data stream according to the coding configuration of the foreground, and sending the coded data stream to the foreground so as to display the data stream on the foreground.

In the embodiment of the present invention, after performing encoding processing on a data stream according to encoding configuration of a foreground and sending the encoded data stream to the foreground, the method further includes: receiving a code change message sent by a foreground; determining the changed coding configuration of the foreground according to the coding change message; coding the data stream according to the changed coding configuration of the foreground to generate a coding changed data stream; and sending the data stream with the changed codes to a foreground so that the foreground displays the data stream with the changed codes.

In the embodiment of the invention, the data stream with the changed codes is obtained by coding the data stream according to the code configuration changed by the foreground, so that the foreground can normally display the data stream, and the code configuration of the character set of the login data returned by the target remote server is changed at the browser end. The encoding is character set encoding, the encoding processing is character set encoding in the encoding configuration for converting the data stream into the foreground, the character set encoding can be utf-8 encoding, can also be Chinese character set encoding such as gbk and gb2312, and can also be expanded multi-language character set encoding.

In the embodiment of the present invention, before sending the data stream after the encoding process to the foreground, the method includes: and responding to the changed row and column numerical values of the display window sent by the receiving foreground, and adjusting the row and column numerical values in the data stream after the coding processing according to the changed row and column numerical values of the display window, wherein the changed row and column numerical values of the display window are obtained by the receiving foreground through monitoring an event indicating the change of the row and column numerical values of the display window.

Monitoring an event of a change of a row and column value of a display window by a foreground, for example, when a user changes the size of a display window of a browser, triggering a resize event, monitoring and capturing the resize event in real time by the foreground, then analyzing the row and column value of the display window from the resize event, namely the row number and column number of the display window, sending the row and column value of the changed display window to the background by the foreground, obtaining the row and column value of the changed display window through socket connection before sending a data stream after encoding processing to the background, and then adjusting the row and column value in the data stream after encoding processing, so that the adjusted data stream after encoding processing is adapted to the size of the display window of the foreground, thereby realizing adaptive adjustment.

In one embodiment, the foreground shows the encoded data stream, including: js, displaying the coded data stream received by the socket connection to the browser by the foreground, and adaptively adjusting the displayed row and column numerical values.

In the embodiment of the invention, when the background establishes session connection with the foreground and the remote server, namely under the condition that the session connection is effective, the foreground and the target remote server can perform file transmission, including file uploading, file downloading and the like. Specifically, a file transmission instruction which is sent by the foreground and aims at the target remote server is received, wherein the file transmission instruction indicates a file to be transmitted and a remote path; and sending a file transmission request to the target remote server based on the file transmission instruction so as to enable the target remote server to transmit the file to be transmitted to the position specified by the remote path. When the file is transmitted, a user selects a file to be transmitted and a remote path, the foreground sends the file to be transmitted to the background, the background sends a file transmission request to a target remote server after receiving the file to be transmitted, and the file transmission request is transmitted to a position designated by the remote path, so that file list information and file permission information can be checked. Alternatively, the file transfer request may be an sftp request, where sftp is a secure file transfer protocol, a secure method of transferring a file over a network.

In an embodiment of the present invention, the method further includes: and receiving a change request aiming at the remote server list sent by the foreground, and changing the remote server list based on the change request. Optionally, the change request for the remote server list may be a change of information of the remote server in the remote server list, or a change of the number of the remote servers in the remote server list, where the change may be one or more of addition, modification, and deletion. Alternatively, the changes may be to one or more pieces of remote server information. When the information of the remote server is newly added, the foreground directly imports the file (such as an excel format file) of the information of the newly added remote server, the user judges whether the file has the information needing to be modified, if so, the file can be modified on the page, and if not, the file is sent to the background, so that the batch management of the information of the remote server is realized. When a piece of remote server information in the remote server list needs to be deleted, the information is selected to be deleted from the list; when a piece of remote server information needs to be newly added, the user fills in the remote server information; and if one piece of information needs to be modified, directly selecting the piece of information for modification, receiving a change request sent by a foreground, and obtaining a changed remote server list.

The method of the embodiment of the invention realizes the change of the remote server list by receiving the change request of the remote server list sent by the foreground, so that the information of the remote server can be maintained singly or in batch by the foreground.

In the embodiment of the invention, after the coded data stream is sent to the foreground, namely under the condition of session connection, when an operation instruction aiming at a target remote server sent by the foreground is not received within preset time, the session connection with the foreground and the remote server is disconnected. If the user does not respond after time out, if the user does not trigger the keyboard time for a long time, the system considers the conversation to be invalid, and the conversation connection is disconnected.
