Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.

The embodiment of the application provides an information acquisition method, an information acquisition device and a storage medium. The information acquisition device may be integrated in a computer device, and the computer device may be a server or a terminal.

For a better understanding of the embodiments of the present application, reference is made to the following terms:

peer-to-peer network: Peer-to-Peer (Peer-to-Peer, abbreviated as P2P) is a distributed application architecture for distributing tasks and workloads among peers (peers), and is a networking or network form formed by Peer-to-Peer computing model in application layer. In a P2P network environment, multiple computer devices connected to each other are in a peer-to-peer status, each computer device has the same function, and there is no master-slave relationship, and one computer device can be used as a server (GO, i.e. group owner) to set shared resources for other computer devices in the network, and also as a workstation (GC, i.e. group user), and the whole network generally does not rely on a dedicated centralized server, nor has a dedicated workstation. Each computer in the network can both act as a requester of network services and provide resources, services and content in response to requests from other computers. Typically these resources and services include: sharing and exchange of information, computing resources (e.g., central processor computing power sharing), storage sharing (e.g., use of cache and disk space), network sharing, printer sharing, and the like.

WiFi-Direct: namely, WiFi direct connection, like WiFi P2P, can enable devices to perform point-to-point direct interconnection through a Wireless Local Area Network (WLAN) without an intermediate access point.

The peer device: in a P2P network environment, multiple computer devices connected to each other are in a peer-to-peer status, and each computer device has the same function, and has no master-slave distinction, so a device establishing peer-to-peer network connection may be called an opposite device.

IP address: the IP Address (Internet Protocol Address) refers to an Internet Protocol Address and is translated into an Internet Protocol Address. The IP address is a uniform address format provided by the IP protocol, and it allocates a logical address to each network and each host on the internet, so as to mask the difference of physical addresses.

MAC address: the MAC Address (Media Access Control Address) translates to a MAC Address, also called a local area network Address (LAN Address), a MAC Address, an Ethernet Address or a Physical Address, which is an Address used to identify the location of the network device. In an Open System Interconnection Reference Model (OSI Model for short), a third layer network layer is responsible for an IP address, and a second layer data link layer is responsible for a MAC address. The MAC address is used to uniquely identify a network card in the network, and if one or more network cards exist in a device, each network card needs to have a unique MAC address.

Socket: sockets are abstractions of endpoints that communicate bi-directionally between application processes on different hosts in a network. A socket is the end of a process's communication over a network and provides a mechanism for application layer processes to exchange data using a network protocol. In terms of the position, the socket uplink application process and the socket downlink network protocol stack are interfaces through which the application program communicates through the network protocol, and are interfaces through which the application program interacts with the network protocol root. May be used to complete the transfer of data between two endpoints, for example, may complete the transfer of data between two applications.

Referring to fig. 1, taking an information obtaining apparatus integrated in a computer device as an example, fig. 1 is a schematic view of an implementation environment scene of an information obtaining method provided in an embodiment of the present application, and includes a terminal a and a terminal B, where the terminal a and the terminal B may be various computer devices capable of performing peer-to-peer network connection, such as a smart phone, a tablet computer, a notebook computer, and a desktop computer, but are not limited thereto. The terminal a and the terminal B may be connected in a WiFi direct communication manner, and after the terminal a and the terminal B are successfully connected, the terminal a serves as a group owner, and the terminal B may be at least one terminal, so as to execute a corresponding information acquisition operation, which is not limited herein.

The terminal A and the terminal B can search target equipment and establish peer-to-peer network connection with the target equipment; receiving target broadcast information, and acquiring peer-to-peer network group information according to the target broadcast information; determining a target MAC address of the target device based on the peer-to-peer network group information; acquiring a neighboring device address list, wherein the neighboring device address list comprises a mapping relation between a media access control address of a device and an internet protocol address; and searching the internet protocol address corresponding to the target media access control address based on the adjacent equipment address list.

It should be noted that the schematic diagram of the implementation environment scenario of the information obtaining method shown in fig. 1 is only an example, and the implementation environment scenario of the information obtaining method described in the embodiment of the present application is for more clearly explaining the technical solution of the embodiment of the present application, and does not constitute a limitation to the technical solution provided by the embodiment of the present application. As can be known to those skilled in the art, with the evolution of information acquisition and the emergence of new service scenarios, the technical solution provided in the present application is also applicable to similar technical problems.

The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

The embodiment will be described in terms of an information acquisition apparatus, which may be specifically integrated in a computer device, where the computer device may be a terminal, and the application is not limited herein.

Referring to fig. 2, fig. 2 is a schematic flow chart of an information obtaining method according to an embodiment of the present disclosure. The information acquisition method comprises the following steps:

in step 101, a target device is searched for and a peer-to-peer network connection is established with the target device.

Under a native WiFi-Direct framework of an Android system (Android), after two devices establish peer-to-peer network connection successfully, the local device and its peer-to-peer device form a peer-to-peer network group (P2P group), and data transmission between the two devices needs to be performed through Socket connection establishment between the peer-to-peer network groups. The Socket is formed by combining an IP address and a port, and provides a mechanism for transmitting a data packet to an application layer process, so that the IP address of a peer device needs to be acquired in a peer-to-peer network group, and data transmission between two devices can be realized by establishing Socket connection.

When establishing peer-to-peer network connection, the system will automatically create a peer-to-peer network group without creating a peer-to-peer network group, and randomly allocate the role of each device in the peer-to-peer network group, when the local device is in the group user role, the peer device will be in the group owner role, the local device can directly obtain the IP address of the peer device in the group owner role, for example, the IP address of the peer device in the group owner role can be directly obtained through the wifi 2pinfo.

However, when the local device is in the group owner role, the peer device is in the group user role, and at this time, the local device can only directly acquire the MAC information of the peer device and cannot directly acquire the IP address of the peer device. In the prior art, in the case of native WiFi-Direct framework, two approaches are mostly adopted:

(1) when a WiFi-Direct connection is established between two devices, the probability that a local device is assigned to a group user role is increased by setting a group owner proposal value, that is, setting a proposal value of wifip2pconfig.

(2) When the local device is allocated to a role of a group owner, Socket connection is additionally established and monitoring is carried out, at this time, connection of the peer device needs to be waited, when the peer device actively connects, the IP address of the peer device is obtained through a Socket.

Therefore, the existing method for acquiring the IP address of the peer device is complex, needs an active connection request passively depending on the peer device, and cannot guarantee that the IP address of the peer device can be acquired in time.

Therefore, in order to solve the above problem, an embodiment of the present application provides an information obtaining method, where a target mac address of a target device is determined by receiving peer-to-peer network group information carried in target broadcast information, and a neighboring device address list is obtained, and an ip address corresponding to the target mac address is searched in the neighboring device address list according to the target mac address of the target device, so that peer-to-peer can be obtained without depending on a group role of a peer device on the basis of not changing a native WiFi-Direct framework, and meanwhile, obtaining efficiency of the ip address of the target device is improved.

The method comprises the steps that a peer-to-peer network connection service (WifiP2pService) can be created in a system service (SystemServer), the peer-to-peer network connection service is started, and then surrounding P2P devices can be searched through a startSearch () function of the WifiP2pSettings so as to establish peer-to-peer network connection with a searched target device, wherein the device for establishing peer-to-peer network connection is a peer-to-peer device in a peer-to-peer network group, the peer-to-peer network connection mode can be active connection, namely connection with the target device can be selected when the device is searched; the connection can also be passive connection, namely, a peer-to-peer network connection request sent by other P2P devices is received; the connection can also be actively invited, that is, when a peer-to-peer network group already exists, the device in the peer-to-peer network group can invite other devices to join the group, so as to form a peer-to-peer network group formed by two or more P2P devices; accordingly, a passive invitation connection may also be used, that is, a request for inviting devices in other peer-to-peer network groups to join the group is received, and the like, which is not limited herein.

In step 102, target broadcast information is received, and peer-to-peer network group information is obtained according to the target broadcast information.

The system broadcast receiver may be registered during initialization, and receive broadcast information through the broadcast receiver, and when target broadcast information is received, peer-to-peer network group information (i.e., WifiP2pGroup) is acquired according to the target broadcast information, where the target broadcast information carries status information of peer-to-peer network connection. The Broadcast is a cross-process communication mode in the Android system, and the Broadcast Receiver (Broadcast Receiver) is a standard component in the Android system and can receive information representing the change of the connection state of the peer-to-peer network.

In an embodiment, in order to ensure the accuracy of obtaining the peer-to-peer network group information, before obtaining the peer-to-peer network group information, it may be determined whether the peer device is successfully connected. Specifically, when receiving the target broadcast information, the target network information carried by the broadcast information may be acquired by calling a network information request function, and then the connection state of the device performing peer-to-peer network connection may be acquired by using the target network information. Specifically, the target NETWORK information (NetworkInfo) attached to the target broadcast information may be requested to be acquired through wifip2pmanager.extra _ NETWORK _ INFO, and it may be determined through an isConnected () function of the NetworkInfo whether the currently received target broadcast information is successfully sent out by the device in the peer-to-peer NETWORK group or sent out when the device is disconnected. When the target broadcast information is successfully sent out by the equipment in the peer-to-peer network group, the peer-to-peer equipment is indicated to be successfully connected, and then the peer-to-peer network group information is obtained.

In an embodiment, after it is confirmed that the peer device has completed the connection, the peer-to-peer network GROUP information carried by the target broadcast information may be requested to be acquired through wifip2pmanager.extra _ WIFI _ P2P _ GROUP, and the peer-to-peer network GROUP information may also be acquired through wifip2pmanager.requestgroupinfo () method.

In step 103, a target MAC address of the target device is determined according to the peer-to-peer network group information.

Reading the peer-to-peer network group information, determining the group role of the target device, further acquiring the peer-to-peer network device information of the target device according to the group role, and inquiring the device address information in the peer-to-peer network device information to obtain the target media access control address of the target device.

In an embodiment, the peer-to-peer network group information may be read by calling a role determination function to obtain call information, and a group role of the target device is determined according to the call information, specifically, the group role of the local device, that is, the isGroupOwner () function of the WifiP2pGroup, may be determined by executing the role determination function, so that the call information is received, and when the call information is "True", it indicates that the local device is a group owner role, and the peer device, that is, the group role of the target device is a group user role; when the call information is "False", it indicates that the local device is in the group user role, and the group role of the target device is in the group owner role.

In an embodiment, when the role type of the target device is a group owner role, the peer-to-peer network device information (WifiP2pDevice) of the target device may be acquired by calling a first acquisition function, i.e., the getOwner () function of WifiP2pGroup, and when the role type of the target device is a group user role, the peer-to-peer network device information (WifiP2pDevice) of the target device may be acquired by calling a second acquisition function, i.e., the getClientList () function of WifiP2 pGroup. And inquiring the device address information in the peer-to-peer network device information to obtain the target media access control address of the target device.

In step 104, a list of neighboring device addresses is obtained.

Wherein the list of neighboring device addresses may be generated by executing a target internet protocol command of the network configuration tool. The neighboring device address list includes a mapping between the mac address and the ip address of the device. The target internet protocol command is an ip command in a network configuration tool of a Linux operating system or a Linux-like operating system, and may be, for example, a neighbor option in the ip command, where the neighbor option may also be in an abbreviated form, that is, may be written as a neighbor option, an n option, and the like, and a neighbor device address list may be obtained through the target internet protocol command, and the MAC address of the device in the unified local area network may be checked through the neighbor device address list, and meanwhile, the neighbor device address list includes a mapping relationship between the media access control address of the device and the internet protocol address.

In step 105, the ip address corresponding to the target mac address is searched based on the neighboring device address list.

The mapping relation between the MAC address of the device and the IP address can be included in the neighboring device address list, and the IP address corresponding to the target MAC address can be searched in the neighboring device address list. Specifically, each mac address in the neighboring device address list may be searched according to the target mac address, and when a target mac address corresponding to the target mac address is searched, an ip address in a row where the target mac address is located is obtained. The internet protocol address is the internet protocol address of the target device.

In one embodiment, after obtaining the neighbor address list, in order to facilitate searching the content in the list and thus increase the searching speed, the neighbor address list may be sorted, specifically, since the length of the MAC address is 48 bits (i.e. 6 bytes), where the first 3 bytes represent the number of the network hardware manufacturer, and therefore, each row of address information in the neighbor address list may be sorted according to the network hardware manufacturer number of the MAC address. Furthermore, the target MAC address corresponding to the target MAC address is searched in the MAC address set by acquiring the target MAC address number in the target MAC address, and acquiring the MAC address set of the neighboring device address list, wherein the MAC address is the same as the target MAC address.

As can be seen from the above, in the embodiment of the present application, peer-to-peer network connection is established with a target device by searching the target device; receiving target broadcast information, and acquiring peer-to-peer network group information according to the target broadcast information; determining a target MAC address of the target device based on the peer-to-peer network group information; acquiring a neighboring device address list, wherein the neighboring device address list comprises a mapping relation between a media access control address of a device and an internet protocol address; and searching the internet protocol address corresponding to the target media access control address based on the adjacent equipment address list. Therefore, the target media access control address of the target equipment is determined through the peer-to-peer network group information carried by the target broadcast information, the adjacent equipment address list is obtained, the internet protocol address corresponding to the target media access control address is searched in the adjacent equipment address list according to the target media access control address of the target equipment, and the obtaining efficiency of the internet protocol address of the target equipment is improved.

The method described in the above examples is further illustrated in detail below by way of example.

In this embodiment, the information acquisition apparatus will be described by taking an example in which it is specifically integrated in a computer device. The information acquisition method takes a terminal as an execution main body. Specifically, please refer to fig. 3, and fig. 3 is a schematic flowchart illustrating an information obtaining method according to an embodiment of the present application.

For a better description of the embodiments of the present application, please refer to fig. 3 and fig. 4 together. As shown in fig. 4, fig. 4 is another schematic flow chart of the information obtaining method according to the embodiment of the present application. The specific process is as follows:

in step 201, the terminal searches for a target device, establishes peer-to-peer network connection with the target device, and obtains target network information carried by broadcast information by calling a network information request function when receiving the target broadcast information.

The terminal can create a peer-to-peer NETWORK connection service in a system service, start the peer-to-peer NETWORK connection service, and further search surrounding P2P devices through a startSearch () function of wifi 2pSettings, so as to establish peer-to-peer NETWORK connection with the searched target device, and at the same time, register a broadcast receiver, and further acquire information of peer-to-peer NETWORK connection state change by monitoring broadcast information, where the broadcast information includes target broadcast information carrying the peer-to-peer NETWORK connection state information, and in order to ensure accuracy of acquiring peer-to-peer NETWORK group information, it may be determined whether the peer-to-peer device is successfully connected before acquiring the peer-to-peer NETWORK group information, and specifically, when receiving the target broadcast information, the target NETWORK information carried by the broadcast information may be acquired by calling a NETWORK information request function wifi 2pm manager.

In step 202, the terminal detects the state information of the peer-to-peer network connection according to the target network information, and acquires the peer-to-peer network group information carried by the target broadcast information when the state of the peer-to-peer network connection is a connection state.

Specifically, the target NETWORK information (NetworkInfo) attached to the target broadcast information may be obtained through a wifip2pmanager.extra _ NETWORK _ INFO request, and it may be determined, through an isConnected () function of the NetworkInfo, whether the currently received target broadcast information is sent successfully by a device in the peer-to-peer NETWORK group or when the device is disconnected. When the target broadcast information is successfully sent out by the equipment in the peer-to-peer network group, the peer-to-peer equipment is indicated to be successfully connected, and then the peer-to-peer network group information is obtained.

In step 203, the terminal reads the peer-to-peer network group information and determines the group role of the target device.

The terminal can read the peer-to-peer network group information by calling a role judgment function to obtain calling information, and determine the group role of the target device according to the calling information, specifically, the group role of the local device, namely, the isGroupOwner () function of the WifiP2pGroup, can be judged by executing the role judgment function, so that the calling information is received, when the calling information is "True", the local device is indicated to be the group owner role, and the peer device, namely, the group role of the target device is the group user role; when the call information is "False", it indicates that the local device is in the group user role, and the group role of the target device is in the group owner role.

In step 204, the terminal obtains the peer-to-peer network device information of the target device by calling a first obtaining function when the role type of the target device is the group owner role, and obtains the peer-to-peer network device information of the target device by calling a second obtaining function when the role type of the target device is the group user role.

When the role type of the target device is the group owner role, the terminal may obtain the peer-to-peer network device information (WifiP2pDevice) of the target device by calling a first obtaining function, that is, the getOwner () function of the WifiP2pGroup, and when the role type of the target device is the group user role, obtain the peer-to-peer network device information (WifiP2pDevice) of the target device by calling a second obtaining function, that is, the getClientList () function of the WifiP2 pGroup.

In step 205, the terminal queries the device address information in the peer-to-peer network device information to obtain the target mac address of the target device.

Wherein, the terminal inquires the device address information (DeviceAddress) in the peer-to-peer network device information to obtain the target media access control address of the target device.

In step 206, a target internet protocol command of the network configuration tool is executed, generating a list of neighboring device addresses.

The terminal may generate the neighboring device address list by executing a target internet protocol command of a network configuration tool of the Linux operating system or the Linux-like operating system. The neighboring device address list includes a mapping between the mac address and the ip address of the device.

In step 207, the terminal searches for each mac address in the neighbor address list according to the target mac address.

The mapping relation between the MAC address of the device and the IP address can be included in the neighboring device address list, and the IP address corresponding to the target MAC address can be searched in the neighboring device address list. Specifically, the terminal searches each MAC address item in the neighboring device address list according to the target MAC address.

In step 208, when the target mac address corresponding to the target mac address is searched, the terminal obtains the ip address of the row where the target mac address is located.

When a target media access control address item corresponding to the target media access control address is searched, the terminal acquires an internet protocol address in a row where the target media access control address item is located, wherein the internet protocol address is an internet protocol address of the target device.

As can be seen from the above, in the embodiment of the present application, a terminal searches for a target device, establishes peer-to-peer network connection with the target device, and obtains target network information carried by broadcast information by calling a network information request function when receiving the target broadcast information; the terminal detects the state information of the peer-to-peer network connection according to the target network information, and when the state of the peer-to-peer network connection is a connection state, the terminal acquires peer-to-peer network group information carried by the target broadcast information; the terminal reads the peer-to-peer network group information and determines the group role of the target device; when the role type of the target equipment is the role of a group owner, the terminal acquires the peer-to-peer network equipment information of the target equipment by calling a first acquisition function, and when the role type of the target equipment is the role of a group user, the terminal acquires the peer-to-peer network equipment information of the target equipment by calling a second acquisition function; the terminal inquires the device address information in the peer-to-peer network device information to obtain the target media access control address of the target device; executing a target internet protocol command of a network configuration tool to generate a neighboring device address list; the terminal searches each MAC address item in the neighboring equipment address list according to the target MAC address; when the target MAC address item corresponding to the target MAC address is searched, the IP address of the row where the target MAC address item is located is obtained. Therefore, the target media access control address of the target equipment is determined through the peer-to-peer network group information carried by the target broadcast information, the adjacent equipment address list is obtained, the internet protocol address corresponding to the target media access control address is searched in the adjacent equipment address list according to the target media access control address of the target equipment, and the obtaining efficiency of the internet protocol address of the target equipment is improved.

In order to better implement the above method, an embodiment of the present invention further provides an information acquisition apparatus, which may be integrated in a computer device, and the computer device may be a terminal.
