Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Referring to fig. 1, a schematic flow chart of a device access method provided in an embodiment of the present invention is applied to a server device, where the method includes:
s101: in the starting process, access information for accessing the client equipment to the server equipment is randomly generated to serve as random access information, and the server equipment is determined to work in a random access information mode.
The access information refers to information that the client device needs to use to access the server device. For example, the access information may be a login password and/or a login user name.
In an embodiment of the present invention, the random access information may be access information that is randomly generated during a first power-on starting process of the server device and is used for the client device to access the server device.
The above-mentioned operation of the server device in the random access information mode can be understood as follows: the client device needs to use the above-mentioned mode of accessing the server device using the random access information.
S102, searching client equipment existing in a local area network where the server equipment is located, and taking the client equipment as first-class client equipment.
A local area network may be understood as a network in which a server device and a client device are communicatively connected.
For example, the server device may be a hard disk recorder, the client device may be a video data acquisition device, and accordingly, the hard disk recorder and the video data acquisition device perform video data interaction in the local area network
The server device may be a router, the client device may be a mobile terminal, and accordingly, the router and the mobile terminal perform data interaction in the local area network.
The server device may start to search for the client device existing in the local area network where the server device is located when a certain condition is satisfied. For example, the server device may search for a client device existing in the local area network in which the server device is located after being successfully started; client equipment existing in a local area network can be searched according to preset interval time; or after receiving the search instruction, searching the client devices existing in the local area network where the client devices are located.
S103, the random access information is sent to the first type of client equipment, so that the first type of client equipment is accessed to the server equipment according to the random access information.
And sending the random access information to first-class client equipment, and after receiving the random access information, the first-class client equipment can access the server equipment by taking the random access information as access information. Therefore, when the station is seen from the client device side, the client device can obtain the access information for accessing the server device without inputting the access information to the client device by a user, and then the device is accessed.
S104: and under the condition that the server-side equipment works in the random access information mode, rejecting the remote access request to the server-side equipment.
Since the access of the client device to the server device also belongs to a case of accessing the server device through a network, that is, a case of remotely accessing the server device, in view of this, in an embodiment of the present invention, the remote access request to the server device may be understood as a remote access request other than an access request to the server device by the client device.
The number of client devices existing in the local area network may exceed the maximum number of client devices that can be accessed by the server device, and thus in one implementation, the step of sending the access information to the first type of client device in the step S103 may include the following steps a 1-A3;
a1, determining whether the number of the first type client devices exceeds the number of the access channels of the server device, if yes, executing the following step a2, and if no, executing the following step A3.
The access channel refers to a channel which is provided on the server device and used for accessing the client device. An access channel is used to access a client device.
A2, selecting client devices with access channels from the first class of client devices, and sending the random access information to the selected client devices.
In one implementation, the server device may randomly select a number of client devices with access channels from the first class of client devices, and send the random access information to the selected client devices.
In another implementation manner, when the server device determines that the number of the first-class client devices exceeds the number of access channels of the server device, the server device may send prompt information for selecting the client device to be accessed to a worker, after the worker sees the prompt information, the worker may select the client device that wants to access the server device through the first-class client devices, and the first-class client devices send information of the client device selected by the user, for example, an identifier of the client device, to the server device, and accordingly, the server device determines the client device to be accessed.
A3, sending the random access information to the first type client device.
When the number of the first type client devices does not exceed the number of the access channels of the server device, the server device is indicated to be capable of allowing all the first type clients to access, and therefore the random access information can be directly sent to the first type client devices.
In an embodiment of the present invention, the server device may need to perform information interaction with a network server of a network end in an operation process, and therefore, the remote access request to the server device may be a remote access request to the server device by the network server. Specifically, the following steps B1-B3 may be utilized to establish a communication connection between the server device and the network server:
b1, obtaining the configuration information for communication connection with the network server.
The configuration information may be understood as information for configuring the network, for example, the configuration information may be an IP (Internet Protocol) address, a MAC (Media Access Control) address, and the like.
B2, determining whether the access information is the random access information, and if the determination result is no, executing the following B3.
Since the random access information is randomly generated by the server device during the starting process, in order to let the staff know the random access information, the server device usually displays the random access information to the staff after starting. However, in practical applications, the inventor finds that when the random access information is presented to the staff, the random access information may be seen by people other than the staff, which causes the random access information to be leaked, and reduces the security of the data interaction system. At this time, if the communication connection with the network server is established, a person other than the worker can access the client device to the server device by using the random access information, so that the data interaction system is remotely attacked. Therefore, the safety of the server-side equipment can be greatly improved in the random access information mode, namely under the condition that the client-side equipment needs to use the random access information for equipment access.
And B3, performing network configuration according to the configuration information, and establishing communication connection with the network server.
Since the random access information may need to be modified, in an embodiment of the present invention, a modification instruction for modifying the random access information may be obtained, and the random access information may be modified according to the modification instruction. After the random access information is modified, the client device can not access the server device by using the random access information, and the server can not be considered to work in the random access information mode any more, so that the server device can be determined to work in the non-random access information mode.
Specifically, the modification instruction may carry modified access information, and after receiving the modification instruction, the server device may analyze the modification instruction to obtain modified access information, and modify the random access information into the modified access information.
In another embodiment of the present invention, the obtaining of the modification instruction may specifically be obtaining a modification instruction which is locally generated by a server device and modifies the random access information. That is, in this case, modifying the random access information is an access information modification performed locally at the server device, that is, the random access information modification can be performed only locally at the server device. Therefore, the random access information can be effectively prevented from being modified because the server-side equipment is subjected to remote attack, and the safety of the server-side equipment is ensured.
On the basis of the above situation, in an embodiment of the present invention, after the random access information is modified according to the modification instruction, the access information may be further processed according to the following steps C1 and C2.
C1, storing the access information before modification and the access information after modification.
Because the client device is accessed to the server device according to the access information, after the access information is modified, the access information in the second type of client device which is successfully accessed to the server device is inconsistent with the modified access information in the server device, and at this time, an access fault may occur between the second type of client device and the server device, the access information before modification can be stored, so that the access information in the server device and the second type of client device is consistent, and the second type of client device can be ensured to be normally accessed to the server device in the access process.
After receiving the modification instruction for modifying the access information, the server device may copy the access information before modification, modify the access information obtained by copying according to the modification instruction to obtain the modified access information, and further store the access information before modification and the access information after modification.
The server-side equipment can also generate new access information according to the modification instruction based on the access information before modification, so as to obtain the modified access information and store the access information before modification and the modified access information.
And C2, sending the modified access information to the second type of client device, so that the second type of client device accesses the server device according to the modified access information when accessing the server device next time.
The second type of client equipment is as follows: a client device that has successfully accessed a server device.
The modified access information is sent to the second type of client side equipment, the second type of client side can access the server side equipment according to the modified access information when the server side equipment is accessed next time, and the second type of client side does not need to perform re-access according to the modified access information after the access information is modified in the current access process, so that the condition that the access process is interrupted can be avoided.
After the client device accesses the server device, the client device may preview data sent by each client device that has successfully accessed the server device in a multi-screen manner, and since the access sequence of the client device accessing the server device may not be the sequence intended by the operator, this may result in that the sequence of data displayed on each preview screen is not the sequence intended by the operator, based on which, in an embodiment of the present invention, the data displayed on each screen may be adjusted by using the following steps D1-D2:
d1, when previewing the data sent by the client device that has successfully accessed the server device in the multi-screen mode, adjusting the client device from which the data displayed on each screen comes.
Wherein, one picture corresponds to one client device.
And D2, previewing the data sent by the client device which has successfully accessed the server device in a multi-screen mode according to the adjustment result.
Specifically, after receiving an adjustment instruction from a worker, the server device may adjust the client device from which the data displayed on each screen comes. For example, currently, 4 data sent by the second type of client devices are previewed in a 4-screen manner, where a screen 1 previews data sent by a client device a, a screen 2 previews data sent by a client device B, a screen 3 previews data sent by a client device C, and a screen 4 previews data sent by a client D, when a worker wants to exchange data displayed on the screens 1 and 4, the worker can click and drag the screen 1 to a position where the screen 4 is located, after determining a drag operation of the worker, the server device displays data sent by the client device D on the screen 1, and displays data sent by the client device a on the screen 4.
The server-side device can also adjust the client-side device from which the data displayed on each picture comes according to the similarity between the data sent by each second-class client-side device, and display the data with high similarity in the adjacent pictures. For example, in a video data interaction system, a plurality of video data acquisition devices are generally used to acquire video data at the same position and at different angles, and the similarity between the video data acquired at the same position and at different angles is very high, so that the server device can adjust the video data acquisition device from which the data displayed by each picture comes according to the similarity between the video data sent by each video data acquisition device, and display the video data acquired by the video data acquisition device and having high similarity through adjacent pictures.
As can be seen from the above, when the solutions provided in the above embodiments are applied to device access, the server device randomly generates access information for the client device to access the server device in a starting process, as random access information, and determines that the mode in which the server device operates in this case is a random access information mode. And then searching client equipment existing in the local area network, and sending the random access information to the searched client equipment, so that the searched client equipment is accessed to the server equipment according to the random access information. In addition, when the server device works in the random access information mode, the remote access request to the server device is refused. It can be seen that, when the solutions provided by the above embodiments are applied to device access, no operation is required by a user in the whole access process, so that the process of inputting access information by the user is not involved, and further the access information is not seen by other users.
