[0109] Exemplary embodiments of the present application are described below with reference to the accompanying drawings, which include various details of the embodiments of the present application to assist in understanding them. These should be considered as merely exemplary. Thus, those of ordinary skill in the art will recognize various changes and modifications of the embodiments described herein, which do not depart from the scope and spirit of the application. Also, descriptions of known functions and constructions are omitted in the following description for clarity and conciseness.

[0110] Figure 1 is a schematic diagram of the main flow of a remote server management method according to an embodiment of the present application, as shown in Figure 1 The remote server management method comprises the following steps:

[0111] Step S101: In response to receiving a login request sent by a foreground, a session connection between the foreground and a target remote server is established; the login request indicates login information and the target remote server;

[0112] Step S102: Login data corresponding to the login information returned by the target remote server is received;

[0113] Step S103: The login data is converted into a data stream, the data stream is encoded according to an encoding configuration of the foreground, and the encoded data stream is sent to the foreground to enable the foreground to display the encoded data stream.

[0114] In the embodiment of the present application, in step S101, a login request sent by a foreground is received, the login request indicates login information and a target remote server, and the login information comprises at least one of a login account, a login password, etc.

[0115] In the embodiment of the present application, the foreground can be a browser terminal, such as a web browser terminal, and the background can be a server corresponding to the foreground.

[0116] Optionally, before receiving the login request sent by the foreground, a selection instruction of the target remote server from a remote server list by the foreground is received to determine the remote server. That is, a user configures a query condition according to a demand, obtains a remote server list according to the query condition, then selects one or more remote servers from the remote server list, and sends the selection instruction to the background, so that the background takes the one or more remote servers selected by the foreground as the target remote server.

[0117] Optionally, the session connection between the foreground and the target remote server is established by: checking the login request, and establishing a socket connection with the foreground after the check is passed; and matching the target remote server according to the login request, and establishing a remote connection with the target remote server. The foreground establishes a socket connection, i.e. a websocket connection, with the background, so that the foreground and the background establish a long connection, data is sent and received through the socket connection, and a customized interface can be made according to the message content. The remote connection can be an ssh connection, or an rdp connection, an rsh connection, etc. The background establishes an ssh connection with the target remote server, data is sent and received through the ssh connection, so that the background can access the target remote server through the ssh protocol, the connection is persistent, and thus the session connection between the foreground and the target remote server is established.

[0118] Optionally, after the socket connection with the foreground is established, a timing heartbeat detection is performed, i.e. the connection state of the background and the foreground is detected in a timing manner, and the validity of the session is detected.

[0119] In an embodiment, the target remote server is matched according to the login request, and a remote ssh connection is established with the target remote server, including: using the Open-ssh technology, and obtaining the ssh connection with the target remote server according to the login request.

[0120] The ssh is a security protocol created on the basis of an application layer and a transport layer, provides a secure transmission and use environment for a shell of a computer, is a traditional network service program, the ssh connection is a connection based on the ssh protocol, the rdp connection is a connection based on the rdp protocol, and the rsh connection is a connection based on the rsh protocol.

[0121] In the embodiment of the application, the login request is checked, including checking login information. The login information includes a login account, the login account can be checked, and it is judged whether the login account has the permission to log in to the target remote server, if yes, the check is passed. Before the login information is checked, a list of login accounts having the permission to log in to the target remote server is configured in advance, if the login account included in the login information is in the list of login accounts, the corresponding target remote server can be logged in. For example, a list of normal accounts and a list of administrator accounts can be configured in advance, so that the login permission of the login account to the target remote server is judged, the permission isolation of the management server of different users in a test environment is realized, and the management permission of the server of different users is limited.

[0122] The target remote server can exist target servers that need to be authorized, and the authorization code needs to be checked for the target remote servers that need to be authorized, and the target remote servers that do not need to be authorized do not need to be checked for the authorization code. Optionally, the login request further includes the authorization code for the target remote server, and the login request is checked, including checking the authorization code, such as the authorization code for the target remote server in the login request being the same as the configured authorization code for the target remote server, and the checking is passed. By making the user log in to the target remote server through the authorization code and checking the authorization code, the access strategy is configured, the management permission of the user for different servers can be limited, the management flexibility is high, the work efficiency can be improved, and the management ability of the system service is improved.

[0123] Optionally, when the login information and / or the authorization code in the login request are checked and the checking is passed, the login information and / or the authorization code and the stored login authentication information, server password and other information of the target remote server are sent to the target remote server to match the target remote server, and the remote connection with the target remote server is realized. The foreground does not need to input the login authentication information, server password and other sensitive information of the target remote server, and the login management is performed by the background, so that the user has the permission to manage the target remote server in the current session process without knowing the server password, so that when the user performs remote server management on a public device, the leakage of sensitive server information is avoided, and the security risk is reduced. The user obtains the operation session control right of the user with the permission without mastering the sensitive information.

[0124] When the session connection with the foreground and the remote server is established, the login data corresponding to the login information returned by the target remote server is received, and the login data is returned to the foreground. When the login data is returned to the foreground, the login data is converted or encapsulated into a data stream (stream), so that the session is exchanged in the form of the data stream, the number of sensitive information interactions is reduced, and the leakage of sensitive information can be effectively avoided. Then, the encoding configuration of the foreground is obtained through the socket connection, the data stream is encoded according to the encoding configuration of the foreground, the encoded data stream is sent to the foreground, and the foreground is displayed.

[0125] In the embodiment of the application, after the data stream is encoded according to the encoding configuration of the foreground and the encoded data stream is sent to the foreground, the method further includes: receiving an encoding change message sent by the foreground; determining the changed encoding configuration of the foreground according to the encoding change message; encoding the data stream according to the changed encoding configuration of the foreground to generate an encoded data stream; and sending the encoded data stream to the foreground to display the encoded data stream.

[0126] In the embodiment of the present application, the data stream is encoded according to the changed encoding configuration of the foreground to obtain an encoded data stream, so that the foreground can be normally displayed, and the encoding 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 converting the data stream into the character set encoding in the encoding configuration of the foreground, the character set encoding can be utf-8 encoding, gbk, gb2312 and other Chinese character set encoding, and can also be extended to multi-language character set encoding.

[0127] In the embodiment of the present application, before the data stream after encoding processing is sent to the foreground, it comprises: in response to receiving the changed row and column values of the display window sent by the foreground, adjusting the row and column values in the data stream after encoding processing according to the changed row and column values of the display window, wherein the changed row and column values of the display window are obtained by the foreground by listening to the event indicating the change of the row and column values of the display window.

[0128] The foreground listens to the event of the change of the row and column values of the display window, for example, when the user changes the size of the browser display window, the resize event is triggered, the foreground listens to and captures the resize event in real time, then parses the row and column values of the display window from the resize event, that is, the number of rows and columns of the display window, then the foreground sends the changed row and column values of the display window to the background, and the background obtains the changed row and column values of the display window through the socket connection before sending the data stream after encoding processing to the foreground, then adjusts the row and column values in the data stream after encoding processing, so that the adjusted data stream after encoding processing adapts to the size of the display window of the foreground, and realizes self-adaptive adjustment.

[0129] In one embodiment, the foreground displays the data stream after encoding processing, comprising: the foreground displays the data stream after encoding processing received by the socket connection to the browser according to xterm.js, and the row and column values of the display are self-adaptively adjusted.

[0130] In the embodiment of the present application, when the background establishes a session connection with the foreground and the remote server, i.e. in the case that the session connection is valid, the foreground can perform file transmission with the target remote server, including file uploading, file downloading, etc. Specifically, a file transmission instruction sent by the foreground to the target remote server is received, the file transmission instruction indicating a to-be-transmitted file and a remote path; based on the file transmission instruction, a file transmission request is sent to the target remote server, so that the target remote server transmits the to-be-transmitted file to a position specified by the remote path. That is, when file transmission is performed, the user selects a to-be-transmitted file and a remote path, the foreground sends the to-be-transmitted file to the background, the background receives the to-be-transmitted file and sends a file transmission request to the target remote server, and the file is transmitted to the position specified by the remote path, so that the file list information and the permission information of the file can be viewed. Optionally, the file transmission request can be an sftp request, where sftp is a secure file transfer protocol, a secure method for transmitting files over a network.

[0131] In the embodiment of the present application, the method further includes receiving a change request for 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 can be a change of remote server information in the remote server list, or a change of the number of remote servers in the remote server list, where the change can be one or more of adding, modifying, and deleting. Optionally, the change can be for one or more pieces of remote server information. When adding remote server information, the foreground directly imports a file (such as an excel format file) of the added remote server information, the user judges whether there is information that needs to be modified in the file, if there is, the file can be modified on the page, if not, it is sent to the background, thereby realizing batch management of remote server information. When a piece of remote server information in the remote server list needs to be deleted, the piece of information is selected and deleted from the list; when a piece of remote server information needs to be added, the user fills in the remote server information; if a piece of information needs to be modified, the piece of information is directly selected and modified, the change request sent by the foreground is received, and the changed remote server list is obtained.

[0132] The method of the embodiment of the present application changes the remote server list by receiving a change request for the remote server list sent by the foreground, so that the remote server information can be maintained by the foreground in single piece or in batch.

[0133] In the embodiment of the present application, after the data stream processed by encoding is sent to the foreground, in the case of session connection, if no operation instruction for the target remote server sent by the foreground is received within the preset time, the session connection with the foreground and the remote server is disconnected. For example, if the user does not respond for a long time, the system considers that the session is invalid and disconnects the session connection.

[0134] As shown in Figure 2 a flowchart of a method for remote server management according to an embodiment of the present application, the method comprises:

[0135] Step S201: receiving a login request sent by the foreground, requesting to establish a socket connection, the login request indicating login information, an authorization code and a target remote server;
