Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Micro-services refer to the development of a single small but business-enabled service, each with its own processing and lightweight communication mechanism, that can be deployed on a single or multiple servers.
The goal of the microservice architecture model is to build large, complex, long-running applications as a set of interrelated services, each of which can be easily locally improved.
Currently, most systems are deployed on a remote host in the processes of project management, program development and the like, and a user needs to access the remote host through a local special client or a browser. In the prior art, the remote host is accessed through a browser by a Web application framework based on Spring MVC and is accessed through an HTTP protocol. In a Web application framework based on Spring MVC, M refers to a data model, V refers to a user interface, C refers to a controller, the controller is responsible for processing requests distributed by a front-end controller, data in the user requests are packaged into the data model after being processed by a service processing layer, and then the data model is returned to the corresponding user interface for displaying. However, the configuration of the Web application framework of Spring MVC is complex, and the system response and processing speed is slow, so that the user can access the remote host computer through the browser installed locally on the terminal device.
The main idea of the application is to create an SSH micro-service for establishing a connection between a terminal device and a remote host through a Secure Shell (SSH) based on a micro-service architecture, for example, a Spring Cloud architecture, and a user sends a first message for requesting to acquire identification information of the SSH micro-service to a backend device, for example, a server, through a gateway device; the back-end equipment sends the identification information of the SSH micro-service to the terminal equipment after receiving the message; after receiving the identification information, the client sends a second message comprising the identification information and the remote host information to the back-end equipment; and the back-end equipment controls the terminal equipment to establish connection with the remote host through SSH micro-service according to the identification information and the information of the remote host. By using SSH microservice dedicated to enabling the terminal device and the remote host to establish a connection via secure shell protocol, the efficiency of the terminal device accessing the remote host can be improved.
Fig. 1 is a schematic diagram of an application scenario of a remote host access method provided in the present application, as shown in fig. 1, including at least one terminal device 101, a gateway 102, at least one backend device 103, and at least one remote host 104.
The terminal device 101 may be an electronic device such as a computer or a mobile phone, and the terminal device 101 is in communication connection with the gateway 102. The terminal device 101 is used for communicating with the backend device 103 through the gateway 102; after the terminal device 101 and the remote host 104 establish a connection, the terminal device 101 is also used to communicate with the remote host 104.
The backend device 103 may be a server, and the backend device 103 is communicatively connected to the gateway 102. The backend device 103 deploys at least one micro service, and the at least one micro service includes an SSH micro service, and the SSH micro service is used for enabling the end device and the remote host to establish a connection through SSH.
Remote host 104 may be a server, and remote host 104 is communicatively coupled to gateway 103. Remote host 104 may have deployed thereon a project management system, a program development system, and the like.
The Gateway 102 may be Spring Cloud Gateway, Netflix Zuul, etc., and is not limited specifically. Gateway 102 may also be used for load balancing in addition to the functions described above.
In the micro-service architecture, the granularity of the service is further subdivided, and each service can be independently designed, developed, tested, deployed and managed. In this case, each independent deployment unit may be maintained by different development and test teams, and may be designed using different programming languages and technical platforms, which requires that a language and platform independent service protocol must be used as a communication means, i.e., a gateway, between each unit. The gateway can simplify the calling logic of the front end in the project and simplify the complexity of mutual calling among internal services; the specific function is forwarding service, and all internal and external client calls are received and forwarded; other common functions are authentication of authority, current limit control, etc.
The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flowchart of a remote host access method provided in the present application, where the method is applied to a server, and the server is deployed with an SSH microservice, as shown in fig. 2, the method includes:
s201, receiving a first message sent by the terminal device through the gateway.
The first message is used for requesting to acquire identification information of the SSH micro-service.
The terminal equipment can be electronic equipment such as a mobile phone, a computer and the like. The first message sent by the terminal device through the gateway may be triggered by the user by operating a browser, client, etc. on the terminal device.
The Gateway can be Spring Cloud Gateway, Netflix Zuul, etc. When the terminal device sends a plurality of messages to the server through the gateway, the gateway can route the messages to corresponding services according to different message contents, and the services are deployed on the server so that the server processes the messages through the services. When the gateway is connected with a plurality of servers, after the gateway receives a plurality of messages sent by the terminal equipment, the plurality of messages can be respectively routed to the services corresponding to the plurality of messages on different servers according to the preset rule, and the response speed to the user operation is improved.
The SSH micro-service is a service deployed on a server for establishing a connection between a terminal device and a remote host through an SSH protocol. Services for realizing other services can be deployed on the server, a lightweight system framework can be realized by building a system based on Spring Cloud micro-service architecture on the server, each service can be independently developed, and then the rapid development of SSH micro-services can be realized, and the development efficiency of the service is improved; on the other hand, each service in the micro-service architecture is autonomous, so that the processing efficiency is high, and the efficiency of establishing connection between the terminal equipment and the server can be improved by using the SSH micro-service.
S202, according to the first message, sending identification information of the SSH micro service to the terminal equipment.
Specifically, when the server receives the first message, the server sends identification information of the SSH micro-service to the terminal equipment through the gateway; when the server receives other messages, other information corresponding to the other messages is sent to the terminal equipment through the gateway, and certainly, when the server receives the other messages, the server may not perform any processing or send any information to the terminal equipment; for example, when the server receives a message requesting for querying the remaining memory capacity of the server, the server may send, to the terminal device through the gateway, identification information of the micro service querying the remaining memory capacity of the server.
S203, receiving a second message sent by the terminal device through the gateway.
Wherein the second message includes identification information and information of the remote host.
The information of the remote host may include a name, an Internet Protocol (IP) Address, a domain name, a Media Access Control (MAC) Address, and the like of the remote host, and may further include information such as a model, a brand, a processor model, or a memory size of the remote host.
And after receiving the second message sent by the terminal equipment, the server calls the corresponding micro service according to the second message including the identification information, and processes the second message sent by the terminal equipment through the micro service. For example, after receiving the second message sent by the terminal device, the server invokes the SSH microservice according to the identifier information of the SSH microservice included in the second message, and processes the second message sent by the terminal device through the SSH microservice, where the specific processing procedure refers to the following steps.
And S204, controlling the terminal equipment to establish connection with the remote host through SSH micro service according to the identification information and the information of the remote host.
Specifically, after receiving the identification information of the SSH microservice sent by the terminal device, the server directly calls the SSH microservice to process the second message; after receiving the information of the remote host sent by the terminal equipment, the server can determine the remote host which the terminal equipment requests to be connected through the SSH micro-service and enable the terminal equipment to be connected with the remote host.
In the application, a server receives a first message which is sent by a terminal device through a gateway and used for requesting to acquire identification information of SSH micro-service; according to the first message, sending identification information of the SSH micro service to the terminal equipment; then the server receives a second message which is sent by the terminal equipment through the gateway and comprises the identification information and the information of the remote host; according to the identification information and the information of the remote host, the control terminal equipment is connected with the remote host through the SSH micro-service, and a system based on the micro-service architecture can realize a light-weight system architecture and can realize the rapid development of the micro-service; meanwhile, the SSH micro-service realizes that the terminal equipment is connected with the remote host, so that the response speed of the system can be improved, the service processing capacity of the system can be improved, and the efficiency of accessing the remote host by the terminal equipment can be improved.
Fig. 3 is a schematic flowchart of another remote host access method provided by the present application, where the method is applied to a server, where the server is deployed with an SSH micro service, and fig. 3 further illustrates that, based on the embodiment shown in fig. 2, S204 controls a terminal device to establish a connection with a remote host through the SSH micro service according to identification information and information of the remote host, and as shown in fig. 3, the method includes:
s301, receiving a first message sent by the terminal device through the gateway.
The first message is used for requesting to acquire identification information of the SSH micro-service;
s302, according to the first message, sending identification information of the SSH micro service to the terminal equipment.
S301-S302 are similar to S201-S202, and reference may be made to the description of S201-S202, which is not repeated herein.
And S303, receiving a second message sent by the terminal equipment through the gateway.
The second message comprises identification information, information of the remote host, account information and password information.
The information of the remote host may include a name, an Internet Protocol (IP) Address, a domain name, a Media Access Control (MAC) Address, and the like of the remote host, and may further include information such as a model, a brand, a processor model, or a memory size of the remote host.
The account information may include words, numbers, letters, pictures.
The password information may include words, numbers, letters, pictures.
The account information and the password information may be the same as the information input by the user, or may be information obtained by processing the information input by the user by the terminal device, for example, the account information and the password information input by the user are respectively encrypted by the terminal device to obtain encrypted account information and encrypted password information.
And S304, verifying the account information and the password information.
If the account information and the password information pass the verification, executing S305; and if the account information and the password information are not verified, sending first error prompt information to the terminal equipment.
The first error prompt message is used for prompting that the user account information and the password information are not verified. The first error prompt message can be in any form of characters, pictures, voice and the like or a combination form thereof.
For example, the verification of the account information and the password information may be the verification of whether the account information is registered and whether the account information and the password match.
The method comprises the steps that whether a user is a legal user or not can be determined by verifying account information and password information of the user, and when the account information and the password information corresponding to the user pass verification, the user is determined to be the legal user, so that the subsequent steps can be continued, and the terminal equipment of the user is connected with a remote host computer which requests access; when the account information and the password information corresponding to the user are not verified, the user is determined to be an illegal user, and the server can send first error prompt information to the terminal device to prompt that the account and/or the password of the user are wrong, so that the calculation amount of the server can be reduced, and meanwhile, the safety can be improved.
S305, determining the access authority corresponding to the account information according to the corresponding relation between the preset account information and the authority.
And determining the access authority corresponding to the account information according to the corresponding relation between the preset account information and the authority, namely determining which host the user can access according to the corresponding relation between the preset account information and the authority. For example, the preset corresponding relationship between the account information and the authority is that the authority of the administrator account can access the remote host a, the remote host B, the remote host C and the remote host D; the authority of the personal account is only to access the remote host bound with the personal account, for example, the personal account 1 only can access the remote host A, the personal account 2 only can access the remote host B, and the like.
By the method, if the remote host which can be accessed by the user is determined, whether the user has the right to access the remote host corresponding to the identification information of the remote host in the second message, namely the remote host which the user requests to access, can be determined according to the remote host which can be accessed by the user.
S306, determining whether the terminal equipment has the authority to access the remote host or not according to the access authority, executing S307 if the terminal equipment has the authority to access the remote host, and sending second error prompt information to the terminal equipment if the terminal equipment does not have the authority to access the remote host.
Wherein the second error prompt message is used for prompting the user that the user has no right to access the remote host which the user requests to access. The second error prompt message can be in any form of characters, pictures, voice and the like or a combination form thereof.
For example, in combination with the above example, assuming that the account information of the user is an administrator and the remote host that the user requests to access is the remote host a, it is determined that the user has the right to access the remote host a; and if the account information of the user is the personal user 2 and the remote host which the user requests to access is the remote host A, determining that the user does not have the right to access the remote host A, and sending second error prompt information to the terminal equipment by the server to prompt the user that the user does not have the right to access the remote host A which the user requests to access.
By the method, if the server determines that the user has the authority to access the remote host requested to be accessed, the server can continue to execute the subsequent steps so as to establish connection between the terminal equipment of the user and the remote host requested to be accessed; if the fact that the user does not have the right to access the remote host requested to be accessed by the user is determined, the server can send second error prompt information to the terminal device to prompt the user that the user does not have the right to access the remote host without continuously executing subsequent steps, and therefore the operation amount of the server can be reduced.
S307, the control terminal device establishes connection with the remote host through SSH micro service.
In this step, one possible implementation manner for the control terminal device to establish a connection with the remote host through the SSH microservice is as follows: sending a third message to the remote host, wherein the third message is used for requesting the remote host to establish connection with the terminal equipment; and receiving a fourth message sent by the remote host, and controlling the terminal equipment to be connected with the remote host according to the fourth message.
Specifically, the server sends a third message to the remote host through the gateway to request the remote host to establish connection with the terminal device, where the remote host is a remote host corresponding to the information of the remote host included in the second message, that is, the server sends the third message to the remote host to which the user requests connection through the gateway to request the remote host to establish connection with the terminal device of the user. If the remote host sends a fourth message to the server, the server controls the terminal equipment to establish connection with the remote host; if the remote host does not send the fourth message to the server, or the remote host does not send the fifth message to the server to indicate that the remote host cannot establish a connection with the terminal device, for example, the remote host is being accessed by other terminal devices, etc., the server may send a prompt message to the terminal device to prompt the user that the remote host is busy, cannot establish a connection, etc.
By the method, the remote host and the terminal equipment can be connected.
Further, optionally, after the server control terminal device establishes a connection with the remote host through the SSH microservice, the server control terminal device may also supervise and control the behavior of the user, and may include the following steps:
s308, acquiring an operation command sent by the terminal equipment to the remote host through the SSH micro-service.
Js and a websocket are connected to build an operation interface of front-end terminal equipment, so that receiving of user shell commands and feedback of host operation are achieved.
For example, the terminal device is connected to a back-end server through a WebSocket on a webpage, and the server is connected to a remote host through an SSH protocol channel to realize a long connection; after the connection is successful, xterm.js simulates a shell terminal in a browser, monitors user operation, and inputs the content input by the user each time into the connected WebSocket; after receiving the operation information through the WebSocket, the server connects the content input by the user to the remote host through the SSH protocol channel for execution; and returning the processing result on the remote host to the server; the server returns the return result to the webpage of the browser on the terminal equipment through the WebSocket; js displays data received from the WebSocket onto the terminal device.
S309, determining whether the operation command meets a preset condition, and if the operation command meets the preset condition, sending first indication information to the remote host.
Optionally, the preset condition includes that the operation command does not belong to the preset operation command set, or the operation command is an instruction triggered by a user and used for disconnecting the remote host from the terminal device.
