The each embodiment of the application utilizes software wireless access point (SoftAP) function of terminal equipment to set up WLAN (wireless local area network) wifi environment, relate to as the operation of the master terminal of hotspot in a local network and create chatroom (also known as room), wait for that visitor's terminal adds, confirms that visitor's terminal adds, chats and dismiss chatroom etc., the operation of corresponding visitor's terminal relates to search chat room, adds chatroom, wait acknowledge, chat and exit chatroom etc.
By reference to the accompanying drawings the application is described in further detail below by specific embodiment.
Embodiment 1:
As shown in Figure 1, the present embodiment provides a kind of LAN communication method, comprises the steps S11-S15:
Networking step S11, master terminal sets up WLAN (wireless local area network) based on software wireless access point function, and arranges from connecting at least one visitor's terminal as hotspot;
Connection Step S13, master terminal creates chatroom and adds for visitor's terminal;
Communication steps S15, master terminal, after visitor's terminal adds chatroom, carries out communication interaction with visitor's terminal.
Above-mentioned steps S11-S15 is more the operating process embodying master terminal side, and visitor's terminal also exists corresponding operating process, and such as, as shown in Figure 2, the operating process of visitor's end side comprises the steps S21-S25:
Networking step S21, visitor's terminal searching hotspot is to enter WLAN (wireless local area network) by hotspot;
Visitor's Connection Step S23, visitor's terminal adds the chatroom being in master terminal establishment in same WLAN (wireless local area network);
Visitor communication steps S25, visitor's terminal carries out communication interaction with the master terminal be in same described WLAN (wireless local area network) and/or other visitor's terminal after adding chatroom.
Above in each step, master terminal and visitor's terminal can be intelligent terminal in such as mobile phone, clustered paging system or the such as terminal such as PC, PDA, and these terminals need to provide SoftAP function and network enabled communication function.In the following description, master terminal (also known as main frame) represents establishment hotspot and sets up the house-owner of chatroom, and visitor's terminal (also known as client computer) represents in WLAN (wireless local area network) other member connecting hotspot.Below for mobile phone as terminal, specifically describe above steps, wherein mobile phone is provided with android system.
For step S11, master terminal is actually the AP function utilizing Android itself, using the network that the signal of master terminal itself connects as other visitor's terminal.In a kind of specific implementation, create one by the mode of programming and specify ssid(Service Set Identifier, service set identification) hotspot, by reflection the setWifiApEnabled function obtained in Wifimanager just can open hotspot.WifiManager provides most of API that management Wifi connects, such as check configured networked lists, the indivedual record of amendment attribute, foundation or close that wifi network connects, the multidate information of inquiry related network state, the scanning result of access point comprised enough information decide needs and what access point connects, etc.; The function of the enable AP function that setWifiApEnabled function then provides for Wifimanager.Concrete establishment focus with reference to existing relevant android development technique, can not describe in detail at this with the mode opening focus.In addition, the AP released due to same manufacturer generally uses identical ssid, once make a stab, the assailant of illegal link utilizes general initialization string to link wireless network, just very easily set up an illegal link, thus bring threat to wireless network, therefore, the present embodiment is when creating the hotspot of specifying ssid, ssid is encoded, adopts base64 coding here.The thought of base64 coding is that the basic ASCII character character of employing 64 carries out recompile to data, specifically with reference to existing base64 coding techniques, can not describe in detail at this process of ssid coding.
The hotspot arranged for finding master terminal, visitor's terminal needs to open wifi module, the startScan function calling WifiManager starts hot spot scanning, the ssid list scanned is obtained by monitoring android system broadcast, then travel through ssid list and base64 decoding is carried out to ssid, and judge whether the naming rule meeting ssid, if met, then think that hotspot corresponding to this ssid is the hotspot needing to search.
After searching hotspot, visitor's terminal calls addNetwork function by WifiManager, and arranges relevant wifi parameter, such as, specify the focus of ssid, just can be connected to this focus to android system application.Now need to monitor android system broadcast, judge wifi state, connect (connected) if wifi state becomes, and the ssid set during ssid and the addNetwork connected is identical, then think that this visitor's terminal has added in WLAN (wireless local area network) corresponding to this hotspot.
For step S13, be the associative operation after master terminal creates focus, as shown in Figure 3, it comprises following sub-step S131-S137:
Room creates sub-step S131, master terminal obtains local IP address and arranges certainly as transmission control protocol server (tcp server after successfully obtaining, Transmission Control Protocol Server), the foundation of tcp server is considered as creating chatroom;
Due to the diversity of Android device, after receiving the AP_ENABLE notice of android system readjustment, can not ensure that one gets local IP address surely, so master terminal needs retry several times after the failure of acquisition local IP address, such as retry 3 times, every minor tick 1 second.If the local IP address of master terminal also cannot be got after retry several times, then determine to create chatroom failure.Master terminal, after successfully getting local IP address, just can set up tcp server.
Broadcast sub-step S133, User Datagram Protocol (udp, the user data protocol) broadcast in master terminal monitoring wireless local area network (LAN), and respond the udp broadcast received, this udp broadcast sends by visitor's terminal the local IP address obtaining master terminal;
The object monitoring udp broadcast is, after visitor's terminal connects focus, need the IP address finding focus founder (i.e. master terminal), master terminal needs reply IP address and listening port to visitor's terminal of specifying after receiving the inquiry broadcast that visitor's terminal sends.If master terminal is monitored unsuccessfully, then determine that master terminal creates chatroom failure.
Socket sub-step S135, master terminal and visitor's terminal are set up socket (socket) and are connected; That is, after master terminal responds the udp broadcast received, wait for that the socket of visitor's terminal connects and determines whether agree to that visitor's terminal connects.
Room request sub-step S137, what master terminal reception and response visitor terminal were sent adds chatroom request.
Master terminal and visitor's terminal are set up after socket is connected, visitor's terminal send request enter chatroom instruction to master terminal, master terminal determines whether agree to that visitor's terminal enters according to demand.If in advance setting can enter the maximum quantity of visitor's terminal of chatroom, the visitor's terminal entering chatroom when request is greater than this maximum quantity, and it is full that master terminal can reply room, or refuse with other reason, then visitor's terminal enters room failure.
Be more than the associative operation of master terminal after establishment focus, certainly, also there is the associative operation after visitor's terminal is connected to AP accordingly, as shown in Figure 4, it comprises following sub-step S231-S237:
IP obtaining step S231, visitor's terminal obtains the machine IP;
Due to the diversity of Android device, after receiving the AP_ENABLE notice of system readjustment, visitor's terminal can not ensure that one gets local IP address surely, so need to carry out several times retry after the failure of acquisition local IP address, such as retry 3 times, every minor tick 1 second.If also cannot local IP address be got after visitor's terminal retry several times, then determine to enter chatroom failure.
Visitor's Broadcast step S233, visitor's terminal sends udp broadcast with the local IP address obtaining master terminal;
Because visitor's terminal does not know the IP address of master terminal, therefore visitor's terminal obtains IP address and the listening port of master terminal by the mode sending udp broadcast, can directly be returned to visitor's terminal after master terminal receives this broadcast.So, if visitor's terminal does not listen to the packet that master terminal is beamed back in the given time, then think that the IP address of searching master terminal is failed, determine that visitor's terminal enters chatroom failure thus.Here the scheduled time can broadcast by sending every the some time udp and repeated several times is determined, such as, sent a udp broadcast every 5 seconds, does not receive packet that master terminal sends yet and then think and search unsuccessfully after repeating 5 times.
Polite formula meets step S235, and visitor's terminal sends to master terminal and sets up socket connection request;
Behind the IP address finding master terminal and listening port, visitor's terminal can initiate IP address and the listening port that socket is connected to master terminal; If socket connection failure, then add chatroom failure.
Request step S237 between guest room, visitor's terminal sends add chatroom request to setting up master terminal that socket is connected with it.
After visitor's terminal is connected to the socket of master terminal, initiates the request adding chatroom, agree to if master terminal is replied, add chatroom success, if master terminal reply room is full or refuse with other reasons, then visitor's terminal adds chatroom failure.In embodiment, if visitor's terminal adds chatroom success, then master terminal can comprise the information about firms of current chat room at the packet that feedback adheres to chatroom, so that guest machine is known.After master terminal agrees to that visitor's terminal adds chatroom, master terminal and visitor's terminal can start session, namely perform step S15.
For step S15, when master terminal and each visitor's terminal carry out communication interaction, if master terminal is as chat messages promoter, then its coding chat messages, and send the chat messages after coding to visitor's terminal; If master terminal is as chat messages transfer person, then the chat messages received is transmitted in WLAN (wireless local area network) except all visitor's terminals except visitor's terminal of chat messages promoter by it.
After master terminal and visitor's terminal carry out communication interaction, also can perform instruction step, namely master terminal detects and characterizes the activity that visitor's terminal entered or left chatroom, then send instruction to other visitor's terminal in WLAN (wireless local area network), to ensure that other visitor's terminal also can simultaneous display visitor's terminal of newly entering chatroom or visitor's terminal of having left.If master terminal cuts out SoftAp function, then represent and dismiss chatroom, or master terminal all visitor's terminals directly can cut out focus after sending the message of cutting out chatroom in local area network (LAN); And the mode that visitor's terminal also connects by disconnecting socket exits chatroom.In another kind of embodiment, between master terminal and visitor's terminal, disconnection detection can also be carried out by the mode sending heartbeat data packets.
The LAN communication method of the present embodiment provides the mode of the social networks in a kind of rapid foundation among a small circle, SoftAp function is utilized to set up hotspot, other user adds emerge WLAN by connecting this focus, master terminal as hotspot is that numerous visitor terminal uses creates a chatroom, under the permission of master terminal, each visitor's terminal using master terminal as agency, realize the communication interaction between visitor's terminal, by this chatroom, local resource is shared to other user between terminal, its data type related to can comprise word, voice, video, picture etc., can select as required in actual applications, and due to direct point-to-point tcp transmission, compare the mode of traditional Bluetooth transmission or the transmission of networking employing special-purpose software, the present embodiment can guarantee the safety and integrity of quality efficiency and the file transmitted.
Embodiment 2:

In the WLAN (wireless local area network) set up by embodiment 1, the chat messages between each terminal (comprising master terminal and visitor's terminal) can be divided into: plaintext message, formatted text message and non-text media message related to resources.Wherein formatted text can be such as Shenzhen Kuaibo Technology Co., Ltd. provide broadcast dedicated resources in player soon as network address, radar, footprint, bookmark etc., non-text media resource can be the media resource that the data volumes such as such as video, music, picture are larger.
The chat messages transmitted between each terminal during specific implementation can adopt message structure body TTChatMessage to represent, it comprises the information such as thumbnail download path of message content, type of message, resource downloading path and resource.For ease of using between multiple system, the encoding and decoding of the message between each terminal can adopt Protobuf storehouse to realize.Protobuf full name Google ProtoBuffer, it is a set of method of data structure being carried out to serializing developed by Google company, it is lower that its message of encoding takies byte number, when multiple platform uses, do not need to re-define message structure, only need to use relevant instrument proto defined file to be generated the correlative code of corresponding language.In embodiment, do not process the Code And Decode of various message in network layer, but place it in SDK layer and carry out, the various network services in SDK layer are all supported to import a decoder into, when receiving message, are carried out the decode operation of being correlated with by decoder.If business upgrades, only need amendment or replace relevant decoder.
For master terminal, contain the connection of all visitor's terminals in local area network (LAN) in its internal memory, during specific implementation, each connection can abstractly be Connection object, and each Connection object contains the method being sent to the other side by Socket.If chat messages initiated by master terminal, it is message call encoder first, is the binary format of specifying, then travels through Connection list object, send a message to visitor's terminal by TTChatMessage object coding.
For visitor's terminal, chat messages between each visitor's terminal carries out transfer by master terminal, namely the chat messages of each visitor's terminal can only be sent to main frame, after master terminal receives message, message is transmitted to other visitor's terminals all in local area network (LAN), the situation of chat messages initiated by the similar master terminal of pass-through mode, master terminal is first resolved after receiving message, to confirm that this message is for chat messages or instruction class message, if chat messages, then forward this chat messages, certainly, master terminal is when forwarding chat messages, need the promoter getting rid of this chat messages.As shown in Figure 5, it illustrates the trend of chat messages between master terminal and visitor's terminal, now master terminal is as tcp server, and visitor's terminal is tcp client(tcp client).The instruction class message produced between master terminal and visitor's terminal can be comprise: request connection, refusal connect, agreement connects, scan lan device, scan hot spot founder, responding scanning, closedown TCP server, room information response, equipment state change, scan A P founder response, heartbeat packet, equipment enters/withdraws from a room, room is full, dismiss room etc.
Due to non-text media resource as the data volume of picture, Voice & Video etc. is usually larger, therefore, can consider not use the TCP channel of master terminal to send for the transmission relating to this kind of media resource, to avoid the transmission of blocking chat and other message instruction.
The present embodiment is the mode using HTTP PULL to the scheme that this adopts, when type of message is non-text media message related to resources, http(Hyper-Text Transfer Protocol opened by each visitor's terminal or master terminal, HTML (Hypertext Markup Language)) service, to be supplied to the download that other visitor's terminal or master terminal carry out file, now, http server(http server is regarded as) as the visitor's terminal initiating non-text media message related to resources, other terminal is regarded as http client(http client), as shown in Figure 6.
Initiate visitor's terminal (i.e. http-server) of non-text media message related to resources when sending this message, the type of message arranging TTChatMessage field is relevant non-text media resource type (as RES_VIDEO, RES_AUDIO etc.), the thumbnail download path of resource downloading path (being such as the reference address of the machine and http server) and resource is set, then relevant message maps is kept in http service, then as transmission plaintext message, message is sent.
As visitor's terminal of message recipient or master terminal (i.e. http client) upon receiving the message, whether the type of message judging TTChatMessage field is non-text media resource type, if, then the relevant information of this message is joined queue management, and carry out the down operation of non-text media resource in suitable, now the interface of terminal may need the information such as display thumbnail, only needs the thumbnail address by comprising in chat messages to carry out downloading.In the http request header (http head) of http client initiation, the GUID(GUID of this http client oneself is included in embodiment) so that it is which http client is at download file that http-server end is known.
In embodiment, according to demand, can set after the file being more than or equal to pre-sizing (such as 10M) needs user to confirm and just start to carry out download transmission, and the file being less than this pre-sizing does not need user to confirm just can automatically download.
Http-server does not carry out too much management to transmit queue, but mapped resource simply.And http client needs to manage transmit queue, such as each http client is maximum can carry out 1 download, so in the queue management of http client, needs transmit queue to be divided into and automatically downloads queue and wait for that user confirms queue.After the download of user to non-text media resource is made and downloaded and confirm, the relevant information of this download will confirm to remove queue from wait user, and add to and automatically download in queue, even can also as first be downloaded preferentially to download.
