In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In some embodiments, a file sharing method is provided, and the file sharing method is applied to a home cloud server, as shown in fig. 1, and may include the following steps:
step S102, establishing Wi-Fi direct connection with each terminal device through a home cloud server, so that a plurality of terminal devices can establish a group.
It should be noted that there are two modes of WiFi: infrastructure mode and AD-HOC mode (i.e., AD HOC network mode). In the infrastructure mode, the access point AP (commonly called as a hotspot or a wireless router) and a plurality of stations STA (user terminals such as computers) are provided, and the stations STA are connected by forwarding messages through the access point AP; in AD-HOC mode, without an access point AP, each WiFi interface communicates with each other through direct connections. Wi-Fi direct is a kind of AD-HOC mode, also called WiFi-P2P, and is a protocol for quickly establishing point-to-point WiFi connection proposed by WiFi alliance, which essentially uses two MACs (Media Access Control addresses, i.e. physical addresses) in technology, so that it can achieve non-interference with wlan. The user group network is a logic isolation sub-network established in a network layer for flexibly supporting isolation of application services, different sub-networks are isolated in communication by default, and user network nodes joining the same group can communicate with each other, namely, a plurality of terminal devices and a home cloud server in the group can communicate with each other.
Specifically, when file sharing is performed, wireless connection between the home cloud server and each terminal device in a home can be achieved through Wi-Fi direct connection, so that a plurality of terminal devices form a group, and file sharing is performed in the group. The terminal equipment and the home cloud server are connected directly through Wi-Fi without a wireless router, so that data transmission is more direct, more convenient and faster.
In some embodiments, establishing Wi-Fi direct with each terminal device through the home cloud server to enable a plurality of terminal devices to establish a group includes: and acquiring the request information of each terminal device, authenticating the request information of each terminal device, and adding the authenticated terminal devices into the group. That is to say, when a terminal device requests to join a group, the home cloud server performs security authentication on the terminal device according to the request information of the terminal device, and allows the terminal device to join the group after the security authentication is passed, so that the security of the group is ensured, and leakage or tampering of shared files caused by illegal terminal devices joining the group is avoided.
In some embodiments, obtaining the request information of each terminal device includes: the authentication information is displayed through a home cloud server, wherein each terminal device generates request information by scanning the authentication information; and receiving the request information sent by each terminal device.
Specifically, the home cloud server may display authentication information, which may be a name, an ID, and the like of the home cloud server, the terminal device has a Wi-Fi direct function, a nearby device list having the Wi-Fi direct function is obtained through scanning of the terminal device by the function, the home cloud server to be connected is searched from the list, and after the home cloud server to be connected is searched, request information is generated based on the authentication information of the home cloud server, and the request information is sent to the home cloud server to request to join a group where the home cloud server is located. After receiving the request information sent by the terminal equipment, the home cloud server carries out security authentication on the terminal equipment based on the request information, and allows the terminal equipment to join the group after the security authentication is passed, so that the security of the group is ensured, and leakage or tampering of shared files caused by illegal terminal equipment joining the group is avoided.
In some embodiments, the requesting information includes a first authentication code generated based on the authentication information, and authenticating the requesting information of each terminal device includes: and generating a second authentication code according to the authentication information, comparing the first authentication code with the second authentication code, and judging whether each terminal device passes the authentication according to the comparison result.
Specifically, after finding a home cloud server to be connected from a device list having a Wi-Fi direct function, the terminal device may generate a first authentication code (e.g., a first key) based on authentication information of the home cloud server by using a predetermined algorithm that is the same as that of the home cloud server, generate request information according to the first authentication code, and send the request information to the home cloud server. After the home cloud server obtains the request information, a second authentication code (such as a second secret key) is generated by adopting a predetermined algorithm based on the authentication information of the home cloud server, and is compared and judged with the first authentication code in the received request information, if the authentication code and the first authentication code are the same, the terminal equipment is allowed to join the group where the terminal equipment is located, otherwise, the terminal equipment is not legal, and the terminal equipment is forbidden to join the group where the terminal equipment is located. Therefore, the same authentication code is generated by the terminal device and the home cloud server through the same algorithm, direct connection of the non-pre-negotiation pointing device can be achieved, and it is guaranteed that a third-party device cannot be disguised as the terminal device or the home cloud server, and therefore the security of the group is guaranteed.
Step S104, sending a corresponding file stored in the family cloud server to the terminal device according to the data request of any terminal device in the group, wherein the node address of each terminal device in the group connected to the family cloud server is different from the routing address of each terminal device connected to the wireless router, so that when the corresponding file stored in the family cloud server is sent to the terminal device according to the data request of any terminal device in the group, each terminal device can surf the internet.
In some embodiments, the node addresses of each terminal device in the group connected to the home cloud server are in the same network segment, for example, the network segment of the group is: 17.0.8.0/21, the home cloud server can be used as group owner, its node address (i.e. IP address) can be 17.0.8.1, the terminal device can be used as group member, its node address can be 17.0.8.2, 17.0.8.3, 17.0.8.4, etc., so that the data transmission is more direct, convenient and fast.
In some embodiments, the node address of each terminal device in the group connecting to the home cloud server is different from the routing address of each terminal device connecting to the wireless router, for example, the network segments of the group are: 17.0.8.0/21, the network segments of the route are: 17.0.5.0/24, to avoid the conflict between node address and routing address to affect the file sharing and the network experience.
In some embodiments, before sending the file stored by the home cloud server to any terminal device in the group according to the data request of the terminal device, the method further includes: and receiving and storing the file uploaded by each terminal device in the group.
Specifically, after a Wi-Fi direct connection is established with each terminal device through a home cloud server, so that a plurality of terminal devices establish a group, bidirectional data transmission can be performed in a group manner, for example, after the home cloud server receives a data request of any terminal device in the group, a stored corresponding file is sent to the terminal device according to the data request; and if the terminal equipment sends the files needing to be backed up to the home cloud server, the files are stored and backed up through the home cloud server.
In the embodiment, the home cloud server is wirelessly connected with each terminal device in a home in a short distance and quickly by Wi-Fi direct connection, and the file sharing between the home cloud server and each terminal device is realized by adopting a group mode, so that the convenience of file sharing is improved, mass data sharing is supported, the bandwidth of a home wireless local area network is not occupied, and the internet experience of the terminal devices is not influenced; meanwhile, safety certification is carried out when the group is established, and the safety of the group is guaranteed.
In some embodiments, after the home cloud server establishes Wi-Fi direct with each terminal device, the method further comprises: receiving a group building request of a user; and establishing a specific group with corresponding terminal equipment establishing Wi-Fi direct connection with a family cloud server according to a group establishment request of a user. Further, after the ad-hoc group is established, the method further comprises: and allocating the node addresses to the terminal devices in the specific group, so that the node addresses of the terminal devices in the specific group are in the same sub-network segment.
Specifically, after the family cloud server and each terminal device establish Wi-Fi direct connection, so that a plurality of terminals establish a group, a user can also send a group establishment request to the family cloud server through any terminal device in the group, after receiving the group establishment request of the user, the family cloud server establishes a specific group for the corresponding terminal device establishing Wi-Fi direct connection with the family cloud server according to the group establishment request, and allocates node addresses to the terminal devices in the specific group, so that the node addresses of the terminal devices in the specific group are in the same sub-network segment. For example, the segments of the group are: 17.0.8.0/21, the family cloud server may be a group owner with a node address of 17.0.8.1, terminal device 1 as member 1, a node address of 17.0.8.2, terminal device 2 and terminal device 3 as member 1's group member 1 and group member 2, respectively, and a node address of 17.0.8.4, 17.0.8.5, respectively, wherein terminal devices 1, 2 and 3 form a specific group of the group. That is, a specific group can be established in the group according to the requirement, so as to perform the file sharing in the specific group.
In some embodiments, the corresponding file stored by the home cloud server is sent to the terminal device based on the node address, and the file uploaded by each terminal device in the group is received.
Specifically, take an example of sending a corresponding file stored by the home cloud server to the terminal device. Determining a target terminal device, specifically a node address of the target terminal device, by the home cloud server according to the data request, and generating a Virtual Private Network (VPN) message with quintuple information by corresponding the node address of the target terminal device to a target group, a target member and a target group member, wherein the target terminal device determines whether the file is sent to itself or not based on a Network segment of the group, the node address of an original member or the node address of the original group member, the node address of the target member or the node address of the target group member, if so, reconstructing the Network segment of the group and verifying, and if not, discarding the VPN message.
For example, as shown in fig. 2, assuming that the left side is a home cloud server and the right side is a terminal device, when the home cloud server sends a file to the terminal device, the home cloud server may obtain a node address of the terminal device according to a data request sent by the terminal device, determine an IP header according to the node address, and generate a VPN packet having quintuple information according to the IP header and data to be sent, where the quintuple information includes the IP header, the data to be sent, a VPN Frame packet header, a VPN public header, and a physical IP header, and send the VPN packet to the terminal device through Wi-Fi direct connection. After receiving a VPN message sent by a home cloud server, a terminal device acquires an IP head from the message, determines whether the VPN message is sent to the terminal device according to the IP head, replaces the group IP with the IP of the message head to send the IP to a VPN layer if the VPN message is sent to the terminal device, enables an inner core to check the IP and then acquires data to be sent in the VPN message, and discards the VPN message if the VPN message is not sent, so that file sharing is achieved.
It should be noted that, for the terminal device uploading a file to the home cloud server and sharing the file among the terminal devices in the specific group, the process may refer to sending a corresponding file stored by the home cloud server to the terminal device, and details are not repeated here.
