The SSH protocol can be used for effectively preventing the information leakage problem in the remote management process. The SSH protocol may encrypt the transmitted data.
The HTTP connection means that the client and the server close the connection after making an HTTP request/response.
In one embodiment, as shown in fig. 1, there is provided a remote data interaction method, including the steps of:
and S11, initiating an http connection by the Web console, and carrying out an http request.
In particular, the Web console is a Web-based user interface that has access to all monitoring data and tasks (operations that can be performed on the monitored computer from the operations console).
Specifically, the http request may be understood as a request message from the Web console to the server. The method comprises the following steps: in the message head line, the request method for the resource, the identifier of the resource and the protocol used. In this embodiment, the http request contains data to be transmitted.
And S12, writing the data to be transmitted into a write buffer queue so that the write buffer queue sends the data to be transmitted to a server through an SSH input end for processing, and acquiring the data to be output.
And the data to be output is data obtained after the server side processes the data to be transmitted.
Optionally, an implementation manner of the step S12 (writing the to-be-transmitted data into a write buffer queue, so that the write buffer queue sends the to-be-transmitted data to a server through an SSH input end for processing, and obtains the to-be-output data) may include:

b. And if the data to be transmitted is input, writing the data to be transmitted into a write buffer queue so that the write buffer queue sends the data to be transmitted to a server side through an SSH input end for processing to obtain the data to be output.
Specifically, the web console is a front xterm plug-in for monitoring keyboard events, and when a keyboard click event is monitored, the monitored characters are sent to a back write buffer queue through an http request. The back end monitors whether the write buffer queue has data to be transmitted or not, if so, the data to be transmitted is read to the SSH input end, the SSH input end sends the data to be transmitted to the server end, and the server end processes the data to be transmitted to obtain the data to be output and returns the data to the SSH output end. Xterm is a terminal simulator on the X Window System, and is used to provide multiple independent SHELL inputs and outputs.
And S13, when the situation that the SSH output end generates the data to be output is monitored, writing the data to be output into a read buffer queue.
Specifically, the back end monitors whether the SSH output end has data to be output, and if the SSH output end has data to be output, the back end reads the data to be output at the SSH output end to the read buffer queue.
The data to be transmitted are temporarily stored through the write buffer queue, the data to be output are temporarily stored through the read buffer queue, and under the condition that the network fluctuates, if packet loss occurs, the data can be obtained from the write buffer queue and the read buffer queue, and the lost data packet is reprocessed.
S14, receiving an http response returned by the read buffer queue through http request polling by taking a preset duration as a period; the http response contains data to be output.
Specifically, an http request is sent to the server at preset time intervals, and when it is monitored that the read buffer queue has data to be output, an http response returned from the read buffer queue is received.
In the embodiment of the application, firstly, a Web console initiates http connection to perform an http request, the http request contains data to be transmitted, the data to be transmitted is written into a write buffer queue, so that the write buffer queue sends the data to be transmitted to a server through an SSH input end to be processed, an http response containing the data to be output is obtained, when the SSH output end is monitored to generate data with output, the data to be output is written into a read buffer queue, and the data to be output sent by the read buffer queue is received through http request polling with preset duration as a period. The http short connection is disconnected after data transmission is finished each time, so that data to be transmitted can be obtained from a background write buffer queue when data is transmitted again, the data to be transmitted is sent to the server to be processed to obtain data to be output, the read buffer queue is monitored by taking the preset duration as a period, the data to be output sent by the read buffer queue is received through http request polling, and therefore remote data interaction between the Web control console and the server is achieved through the http short connection, the problem that the stability of remote data interaction between the control console terminal and the server is poor under the condition that packet loss occurs when a network is disconnected is avoided, and the stability of remote control data transmission is improved.
As an optional implementation manner of this embodiment, step S13 (writing the data to be output into the read buffer queue when it is monitored that the SSH output end generates the data to be output) may be implemented by:
(1) And monitoring whether the SSH output end generates the data to be output or not when the data to be transmitted is written into the SSH input end through the write buffer queue.
(2) And if the SSH output end generates data to be output, writing the data to be output into a read buffer queue.
Illustratively, the back end monitors whether the write buffer queue has data to be transmitted, if the data to be transmitted is to be transmitted, the data to be transmitted is read to the SSH input end, the SSH input end sends the data to be transmitted to the server, and the server processes the data to be transmitted to obtain the data to be output, and returns the data to the SSH output end.
As an optional implementation manner of this embodiment, step S14 (receiving, by polling with a preset duration as a period, an http response returned by the read buffer queue through an http request; where the http response includes data to be output) may be implemented by:
A. and monitoring whether the read buffer queue has data to be output or not by polling through an http request with a preset duration as a period.
B. And if the read buffer queue has data to be output, receiving an http response sent by the read buffer queue.
For example, the preset time period may be 3 seconds, or may be other reasonable values, which is not specifically limited herein and may be determined according to actual situations in the application. For example, every 3 seconds, a front-end timer sends an http request to acquire data in a read buffer queue, monitors whether the data in the read buffer queue is to be output, and if the data in the read buffer queue is to be output, a web console receives the data to be output sent by the read buffer queue.
In some embodiments, after receiving the data to be output, the data to be output is displayed through a web console.
For example, the web console may also display data to be output, for example, the data to be transmitted may be a console command: netstat-a (displaying all monitoring ports), and processing the console command by the server side to obtain the data to be output, namely the states, local addresses, external addresses and used protocols of all the current monitoring ports.
In some embodiments, before the Web console initiates an http connection and makes an http request, the Web console is opened by obtaining the Web permission.
Specifically, before the Web console initiates http connection and makes an http request, a Web login password is acquired, and the Web console is opened.
In some embodiments, before the write buffer queue sends the data to be transmitted to the server through the SSH input end for processing, the server is remotely connected according to the http request, and an SSH channel is established.
Specifically, SSH (Secure Shell) is a Secure channel protocol, and is mainly used to implement remote login and remote copy functions of a character interface. The SSH protocol encrypts data transmissions of both parties of the communication, including user passwords input during user login, and is a security protocol established on the basis of an application layer and a transport layer. In this embodiment, before sending the data to be transmitted to the server for processing, an SSH channel is first established, and remote data transmission can be implemented through the SSH channel.
In some embodiments, the method can be applied to the security access gateway of the internet of things, and is mainly used for remotely managing the gateway in a command line mode. Illustratively, firstly, logging in a security access gateway page of the Internet of things, acquiring web authority, and opening a web console; then, inputting a control command or a gateway management command at a web console terminal; then, the output result of the control command returned by the server is displayed to the web console terminal; and finally, closing the web console terminal, destroying the session at the back end, and disconnecting the http connection. The control command may be ls (view all files), cd/(jump to root directory), cd dir (switch to specified path), and the like, which are only examples and are not limited specifically. In addition, the gateway management command may be a command such as tail (view dynamic log), tail-f (loop read dynamic log), -ntlp (view port number), and the like, and as such, the gateway command is merely exemplified herein and is not particularly limited. Data interaction is carried out by adopting http connection and increasing a data buffer area, retransmission of lost data can be realized under the condition of poor network conditions, the problem of connection interruption caused by packet loss is avoided, and the stability of remote control data transmission is further improved.
In the embodiment of the application, firstly, a Web console initiates http connection to perform an http request, the http request contains data to be transmitted, the data to be transmitted is written into a write buffer queue, so that the write buffer queue sends the data to be transmitted to a server through an SSH input end to be processed, an http response containing the data to be output is obtained, when the SSH output end is monitored to generate data with output, the data to be output is written into a read buffer queue, and the data to be output sent by the read buffer queue is received through http request polling with preset duration as a period.
