Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
To solve the technical problem mentioned in the background art, an embodiment of the present application provides a message transmission method, specifically referring to fig. 1, where fig. 1 is a schematic flow diagram of a message transmission method provided in an embodiment of the present invention, and the method is executed by a server-side virtual port of a virtual terminal device. Before the method steps are introduced, some preparatory tasks that need to be performed will first be explained.
Specifically, it is necessary to configure the same command parsing environment as a console (console) in a virtual port of the virtual terminal device, to configure a debug management cloud wall, to receive cloud wall status or print information, and the like. The virtual ports are remote login virtual ports vty and vty of a router or a switch, and each virtual port comprises a client and a server. The client is configured with an executable file that is independent of the cloud wall. When the cloud wall is operated, the server side can open a channel to wait for connection of the client side. The channel referred to here is the first message transmission channel.
Therefore, before the following steps are performed, the following operations need to be performed at the server:
creating a thread for performing the following operations:
1 message transmission channel pair is created, which in an alternative example may be a first-in-first-out queue fifo (named pipe) pair, including a first message transmission channel, and a second message transmission channel. In a specific example, the first message transmission channel is client-to-server (c 2 s), and the second message transmission channel is server-to-client (s 2 c). After creation, the fifo pair is opened, waiting for client connection in c2 s.
The created thread is also used to perform the following method steps:
Specifically, the operation instruction is written after the user accesses the cloud wall through the virtual port of the client, and the operation instruction is transmitted to the server through c2 s.
And step 120, analyzing the operation instruction to obtain the analyzed operation instruction.
In a specific example, for the parsing of the operation instruction, the client command may be read character by character and parsed.
Of course, if there is a preset character (special character) in the operation instruction, for example, 'tab'? ' then, response operations are performed on the special character. Specific response operations include, but are not limited to, operations such as a prompt operation, a correlation operation, or an autocomplete operation.
In a specific example, for example, the operation commands are secpolarity add xx, secpolarity delete xxx and secpolarity ad-mod xxx, and after executing secpolarity and then spacing, input? Prompt operation is executed, for example, three pieces of information add delete ad-mod are prompted for subsequent selection of keywords;
continuing to execute secpolarity ad to tap tab, the association operation is executed: associating add and ad-mod for selecting specific keywords;
secpolicy ad-continues to be executed, and tab keys are hit, so that an automatic incomplete operation, such as an automatic completion of the keyword ad-mod, is executed because the keyword only has ad-mod at this time.
Specifically, if the analyzed operation instruction is executed, a corresponding operation result is generated. Then the operation result also needs to be fed back to the client. Therefore, it is necessary to switch the first message transmission channel to the second message transmission channel.
Further optionally, after the communication connection between the client and the server is established, c2s and s2c may be replaced by 0 (stdin) and 1 (stdout). And in the subsequent execution process, the switching process between the first message transmission channel and the second message transmission channel is completed by switching between 0 (stdin) and 1 (stdout). So doing, the code can be multiplexed with existing console commands without any modification. The trouble of workers is avoided, and the operation is more convenient and quicker.
It should be further noted that, in this embodiment, the client does not need to parse any command, all command parsing is performed at the server, and similarly, no code needs to be added, so that additional work of a worker is not added.
And step 140, transmitting the operation result to the client through a second message transmission channel.
Specifically, after the operation result is transmitted to the client through the second message transmission channel, the user is displayed through the client. When the operation result is transmitted to the client through the second message transmission channel, the batch transmission mode is adopted to improve the working efficiency. For example 1024 bytes at a time.
In an alternative example, the information sent by the server to the client uses vt100 standard, so that the user can obtain the same result as the console through vty.
According to the message transmission method provided by the embodiment of the invention, the client and the server transmit the message through the message transmission channel, and the message comprises the operation instruction and the operation result generated according to the operation instruction. The information can be acquired at any time through vty of the virtual terminal equipment. The virtual terminal vty is configured with a command analysis environment in advance, wherein the command analysis environment is the same as that of the console, and is used for analyzing the operation command in the environment, completing subsequent configuration and debugging management of the cloud wall according to the analyzed operation command, receiving the cloud wall state or printing information and the like, and therefore the efficiency of solving the problem is improved, and the cloud wall is easier and more reliable to use.
Further optionally, on the basis of the foregoing embodiment, after the operation result is transmitted to the client through the second message transmission channel, the method further includes:
if the client needs to be informed whether the operation result is transmitted or not, or if the operation result of the server active high-speed client is transmitted or not, the following method steps can be executed:
all message transmission channels in the current message transmission channel pair are closed.
And informing the client that the transmission of the operation result is finished by closing all the message transmission channels in the message transmission channel pair.
Further optionally, if the communication connection with the client needs to be established again, the method may further include:
and reopening the message transmission channel pair when establishing the communication connection next time;
and each time the message transmission channel pair is opened again, configuring a new name for the message transmission channel in the message transmission channel pair according to the preconfigured message transmission channel naming rule so as to distinguish the new name from the name of the message transmission channel when the message transmission channel pair is opened last time.
In a specific example, the new c2s and the old c2s are named differently, namely c2s _ e and c2s _ o, e stands for even, o stands for odd, and 0 is used as a starting sequence number, and the new c2s and the old c2s are incremented by 1 each time, namely, the new c2s is opened for the first time to be c2s _ e (0), the new c2s is opened for the second time to be c2s _ o (1), the third time to be c2s _ e (2), the fourth time to be c2s _ o (3), and so on.
Different c2s/s2c pairs are opened through the odd-even sequence number, and the boundary perception from the server side to the client side information is achieved.
Further optionally, when it is detected that the client disconnects the communication connection with the server, the names of the message transmission channels in the message transmission channel pairs are reinitialized.
That is, after the client is disconnected, the server resets the starting sequence number 0, and waits for the client to connect again.
In another embodiment of the present application, another message transmission method is further provided, specifically referring to fig. 2, fig. 2 is a schematic flow chart of a message transmission method provided by an embodiment of the present invention, where the method is executed by a client virtual port of a virtual terminal device, and before introducing steps of the method, a preparation operation executed at a client is first described, where the preparation operation includes: creating a thread for the following:
the method comprises the following steps: 2 threads are created, one thread is used for reading in a user command and sending the command to a server side through c2s fifo; and the other is used for reading in the server-side execution result through s2c fifo and displaying the server-side execution result.
In particular, see the following method steps:
Specifically, as described above, the client is an executable file that is independent of the cloud wall and is run to connect to the cloud wall. Therefore, when the first object opens the client virtual port, the cloud wall is already opened, and the cloud wall can be accessed. And after the first object writes the operation instruction, the client sends the operation instruction written by the first object through a first message transmission channel established with the server. The client reads the user commands one by one, and sends the commands to the server through c2s, and the client can be used for realizing prompting, association or completion functions.
Or, in step 220, after the operation result fed back by the server end is monitored in the second message transmission channel, the operation result is read and displayed.
Wherein the first message transmission channel and the second message transmission channel form a message transmission channel pair.
Specifically, after reading the operation instruction, the client uses a batch reading mode, for example, 1024 bytes are read at a time, and the result is displayed (stdout), and the batch reading mode is used to provide work efficiency.
The message transmission method provided by the embodiment of the invention monitors whether an object accesses the cloud wall through the virtual port of the client of the virtual terminal device in real time, and sends the operation instruction written by the first object through the first message transmission channel established with the server after detecting that the first object accesses the cloud wall through the virtual port of the virtual terminal device. Or, after the operation result fed back by the server end is monitored in the second message transmission channel, the operation result is read and displayed. By the method, the user can easily access the cloud wall through the virtual port of the virtual terminal device, and the operation is convenient. The client and the server establish a communication link through the message transmission channel pair, so that a transmission channel which is simple, convenient and efficient and can be used for transmitting a large amount of data is provided.
Based on the foregoing embodiment, further optionally, after detecting that the first object accesses the cloud wall through the virtual port of the virtual end device, the method further includes the following method steps, which are specifically shown in fig. 3.
In step 310, a first markup file corresponding to a first object is obtained.
And step 340, controlling the first object to exit the access, allowing the second object to access the cloud wall, and storing the second identification file in a preset position.
Specifically, in order to simplify the implementation and the problem of multi-user concurrent access, the vty only allows a single user to log in and is implemented by using a pid file. That is, when the user 1 opens vty to access the cloud wall, the pid of vty is written into a specific file, when the user 2 tries to open vty, it is detected that another process pid is accessing, the user 1 is forcibly quitted, a prompt is given at the user 1 terminal, the user 2 process pid is written into the pid file, and finally, the cloud wall is accessed.
The cloud wall management is generally performed by a controller, vty is convenient to debug, and most users are developers, so that the cloud wall management is designed to be in a single-user mode, and the implementation process is simplified.
Further optionally, as described above, since the client does not perform any processing on the user input command, but only performs a relay function, the ctrl + c is used as a method for exiting vty, and a corresponding signal processing function is set.
Further optionally, the method further comprises:
the termios attribute, - (ICANON | ECHO) is set, the former makes the user input in the non-line mode, the latter removes the playback, i.e. the user input is only played back after the server-side processing.
Further optionally, corresponding to the server side, at the client side, the execution process is summarized as follows:
firstly, a fifo pair is opened according to a starting sequence number (the initial value is 0), connection is established with a server terminal, and user input (stdin) is waited. Reading user commands one by one, and sending the commands to a server through c2 s; waiting for the server to respond; read s2c server-side response, 1024 bytes at a time, and display the result (stdout). And continuously waiting for the input of the user, and repeatedly executing the process.
Certainly, if the client needs to acquire result transmission completion information, the read returns to 0 after the reading is completed, because the server closes the current s2c and opens the new s2c, the client does the same action at this time, closes the current s2c/c2s, updates the starting sequence number, opens the new s2c/c2s to establish connection with the server, and repeatedly executes subsequent operations after the connection is established.
When the client disconnects, the termios attribute is restored and the current c2s and s2c are closed.
Fig. 4 illustrates the whole flow blocks of the server-side thread, the client-side thread, and the user input/output, etc., because the above processes are described in detail in the foregoing, they are not described in detail here.
