FIG. 2 is a schematic structural diagram of a file sharing system according to an embodiment of the present invention.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is a flowchart of a file sharing method provided by an embodiment of the present invention.

The executive body of the file sharing method provided by the present invention can be a corresponding file sharing system, and the file sharing system can be set on the first computer, and the file sharing system can realize file sharing based on the NAS file system.

A file sharing method provided by an embodiment of the present invention may include the following steps:

Step S1: establishing a file sharing connection with the first computer.

Since the shared files of the first computer need to be accessed, the file sharing system needs to establish a file sharing connection with the first computer, and the first computer provides the shared files for other computers to access.

Step S2: Receive a login request sent by the second computer.

After the file sharing system establishes a connection with the first computer that provides the shared file, it needs to connect with the second computer that accesses the shared file of the first computer, so that the second computer realizes an indirect connection with the first computer, and only the first computer is connected. After establishing a connection with the second computer, the second computer can access the shared files of the first computer. Here, the second computer is connected to the first computer by logging in to the file sharing system. The advantage of doing so is that the second computer can be indirectly connected to the first computer, so as to realize the access to the shared files of the first computer, so that the first computer can be accessed. The second computer does not need to establish a connection with the first computer by means of mapping, which avoids that the second computer cannot access the shared files of the first computer due to its own problems and prompts that the second computer and the first computer have realized the mapping connection but the actual connection has not been established. The problem.

Step S3: Perform identity verification on the second computer based on the login request, and if the verification is passed, allow the second computer to log in and access the shared files of the first computer that has established a connection.

Here, the file sharing system may directly authenticate the second computer, or the file sharing system may send the login request to other terminals, and the other terminals will analyze the information according to the received login request, and then the file sharing system will perform information analysis according to the received login request. The information analysis result performs identity verification on the second computer, which is not specifically limited in the present invention.

Only when the authentication of the second computer is passed, the second computer is allowed to log in and access the shared files provided by the first computer, so that the second computer is indirectly connected to the first computer by logging in to the file sharing system. , after the connection is established, the second computer can access the shared files of the first computer. If the identity verification of the second computer fails, the login of the second computer can be directly rejected, or the verification result can be sent to the second computer, and the corresponding identity verification can be performed again after the second computer changes the login request. Of course, in the case that the authentication of the second computer fails, other operations may also be performed, which is not specifically limited in the present invention.

In the file sharing method provided by the present invention, the file sharing system first establishes a connection with the first computer for file sharing, and then connects to the second computer under the condition that the login request of the second computer is passed, so that the second computer can share the file by logging in to the computer. The system accesses the shared files of the first computer, realizes the indirect connection between the first computer and the second computer, and avoids the file sharing process caused by the problem of the second computer itself or prompting that the two computers are directly connected but not actually connected. unstable situation. In conclusion, the file sharing method provided by the present invention solves the technical problem of how to ensure the stability of file sharing between computers.

In a file sharing method provided by an embodiment of the present invention, step S1: establishing a connection for file sharing with the first computer may include:

receiving a connection request for file sharing with the first computer input from the outside world, where the connection request carries the service name of the first computer;

Parse the connection request, obtain the service name of the first computer, and send the CIFS request to the server corresponding to the service name of the first computer;

Receive the verification result returned by the server, and the verification result is sent after the server receives the CIFS request and verifies the CIFS request;

The verification result is analyzed, and if the verification result indicates that the server has passed the verification of the CIFS request, it is determined to realize the establishment of a file sharing connection with the first computer.

The service name of the first computer mentioned here may be the IP address of the server of the first computer, or the domain name of the server of the first computer, etc., which is not specifically limited in the present invention. The file sharing system sends a CIFS request to the server. After the server receives the CIFS request, it can determine the sender of the CIFS request, that is, the file sharing system. If the server allows the establishment of a file sharing connection with the file sharing system, verify that the CIFS request passes, otherwise , then verify that the CIFS request fails; that is, if the server verifies that the CIFS request is passed, it means that it is allowed to establish a file sharing connection based on the CIFS protocol with the file sharing system.

In practical applications, there can be a variety of connection methods for establishing file sharing with the first computer. The simplest one is to establish a connection directly, that is, the server corresponding to the first computer establishes the connection without any verification after receiving the connection request. This makes the process of establishing the connection simple, but because there is no verification process, there is a security problem in the process of establishing the connection. Therefore, in this embodiment, the CIFS request is used to establish a file sharing connection with the first computer. Only when the first computer requests the CIFS The connection can be established only after passing the verification, thus ensuring the security of the connection; and the CIFS protocol corresponding to the CIFS request can enable the program to access the files on the remote computer and request the computer to provide services. In this application, the CIFS protocol is used to make the connection The process is simple and easy to implement, and the time for establishing a connection process for file sharing with the first computer is saved.

In the file sharing method provided by the embodiment of the present invention, the authentication of the second computer based on the login request in step S3 may include:

Parse the login request to obtain the first identity information carried by the login request;

It is judged whether the first identity information is consistent with the preset second identity information, and if so, the verification is passed.

Both the second identity information and the first identity information mentioned here can include one or several parameter items among the service name, share name, user and password, and of course other parameter items can also be set according to actual needs; The parameter items contained in the identity information and the second identity information are consistent, that is, both may include a service name and a shared name, or both may include a user and a password, and the like. The service name refers to the IP address of the server of the first computer; the share name refers to the directory name of the shared file set on the first computer; the user and password refer to the user and password of the shared file set on the first computer.

Since the second computer establishes a connection with the file sharing system by logging in, the second computer needs to be authenticated. The file sharing system can directly perform identity verification on the second computer, first parse the login request to obtain the first identity information carried in the login request, and then determine whether each item of information in the first identity information corresponds to the preset second identity information. The information is the same respectively, if it is, the verification is passed, if not, the verification is not passed. The benefit of the entire process of authenticating directly by the file sharing system is that there is no need to send login requests to other terminals, saving time and increasing efficiency.

Of course, the login request can also be sent to the server corresponding to the first computer; and then the verification result returned by the server corresponding to the first computer is received, and the verification result is that the server corresponding to the first computer verifies whether each item of information carried in the login request is consistent with the pre- The corresponding information in the set identity information is sent after being identical respectively; parsing the verification result, if the verification result indicates that the server corresponding to the first computer verifies each item of information carried in the login request and the preset identity information (that is, the hereinafter mentioned If the corresponding information in the fourth identity information) is the same, the verification passes, otherwise, the verification fails; this can reduce the service pressure of the file sharing system itself. Of course, other settings can also be made according to actual needs, which are not specifically limited in the present invention.

In a file sharing method provided by an embodiment of the present invention, presetting the second identity information may include:

Receive third-party identity information input from the outside world;

sending the third identity information to the server corresponding to the first computer;

Receive the confirmation result returned by the server, where the confirmation result is sent after the server receives the third identity information and confirms whether the third identity information is consistent with the fourth identity information corresponding to the first computer;

The confirmation result is analyzed, and if the analysis result shows that the third identity information is consistent with the fourth identity information, it is determined that the third identity information is the preset second identity information.

Both the third identity information and the fourth identity information mentioned here may include one or more parameter items in the service name, share name, user and password, and generally the parameter items contained in the third identity information and the fourth identity information The same; it can be confirmed whether the third identity information is consistent with the fourth identity information by confirming whether each item of information in the third identity information is consistent with the corresponding information in the fourth identity information. If the corresponding information in the four identity information is consistent, the third identity information is consistent with the fourth identity information, otherwise, the third identity information is inconsistent with the fourth identity information; if the third identity information is consistent with the fourth identity information, it can be determined that the third identity information is consistent with the fourth identity information. The identity information is the preset second identity information, and at this time, the second identity information is also consistent with the fourth identity information. In this way, it can be ensured that the preset second identity information corresponds to the information in the server corresponding to the first computer, and the accuracy of the preset second identity information is enhanced. It can be understood that the two pieces of information are identical in this application.
