Refer to Fig. 1, Fig. 1 is the flow chart of a kind of chat method preferred embodiment based on intelligent terminal home server provided by the present invention.As shown in Figure 1, it comprises the following steps:
S101, client and network server end connect, and send IP address and user profile to network server end, then obtain IP address and the user profile of at least one the good friend's client stored in network server end.
In the present embodiment, when user need chat with the one or more good friends in the buddy list that added in client, need first client and network server end to be connected, and the IP address of client and user profile are sent to network server end, user corresponding to informing network server end client is in line states.Afterwards, then from the one or more good friends the buddy list added, and from network server end the IP address of good friend's client that corresponding acquisition has stored and user profile, namely have selected the object for sending message (also namely for chatting).Wherein, whether online user profile at least include the current information of user.
Preferably, the IP address of the good friend's client stored in described network server end and good friend's client corresponding to user profile are the client connected with network server end.That is, the IP address of the good friend's client stored in described network server end and good friend's client corresponding to user profile are online client.
According to the user profile of described good friend's client, S102, client judge that whether good friend's client is online, then connect according to the IP address of described good friend's client when online, the message receiving user again sends instruction, sends enciphered message to good friend's client home server.
When user have selected the object for sending message, first need judge that whether the other side is online, just can determine whether to connect with the client of the other side.When according to the user profile of the described good friend's client obtained from networking client, client judges that good friend's client is online, then connect according to the IP address of described good friend's client and good friend's client, the message receiving user again sends instruction, sends enciphered message to good friend's client home server.
Client in the present invention and good friend's client all carry home server, the message namely sent between client no longer carries out transfer and storage by network server end (namely background server of the prior art), but by the transfer of client home server and storage, this increase the transfer rate of message, and improve Information Security.
S103, good friend's client home server receive described encrypting messages, are sent to good friend's client and are decrypted and show.
When client is connected with good friend's client home server, namely establishes with good friend's client simultaneously and be connected, now client and good friend's client can mutually send message and chat.In chat process, constantly repeat step S102-S103, when client sends message, be then still the Client(client computer in C/S structure) and the Server(server do not converted in C/S structure); When client receipt message because client home server has received also storing message, then convert the Server(server in C/S structure to).That is, each client is Server in C/S structure, is also the Client in C/S structure simultaneously.
As the preferred embodiment of the present invention, as shown in Figure 2, described step S102 specifically comprises:
According to the user profile of described good friend's client, S201, client judge that good friend's client is whether online, then connect according to the IP address of described good friend's client and ICP/IP protocol and good friend's client home server when online.

Connection in the present invention and communication process all adopt SOCKET to communicate, and observe TCP/IP connection protocol.
The essence of SOCKET communication is exactly write/read/close, and these three actions are mainly used for File operation.A port is opened in the effect of SOCKET, reads write port information, has carried out communication work.Connection procedure between SOCKET can be divided into three steps: server is monitored, client-requested, connects and confirms.
1) server is monitored: be server end SOCKET and the concrete client SOCKET of delocalization, but the state to be connected such as to be in, real-time monitoring state of network.
2) client-requested: refer to and propose connection request by the SOCKET of client, the target that connect is the SOCKET of server end.For this reason, first the SOCKET of client must describe the SOCKET of the server that it will connect, and points out address and the port numbers of server end SOCKET, then just proposes connection request to server end SOCKET.
3) confirmation is connected: refer to when server end SOCKET listens to the connection request receiving client SOCKET in other words, it is with regard to the request of customer in response end SOCKET, set up a new thread, client is issued in the description of server end SOCKET, describe once client confirms this, connect and just established.And server end SOCKET keeps listening state, continue the connection request receiving other client SOCKET.
ICP/IP protocol (Transmission Control Protocol/Internet Protocol, transmission control protocol/internet protocol) is the most basic agreement of Internet.Transmission Control Protocol is reliable and stable interlinkage agreement, and the both sides intercomed mutually will carry out three-way handshake.Main process:
1) user end to server sends a SYN J;
2) server is to client end response SYN K, and carries out confirmation ACK J+1 to SYN J;
3) client rethinks server and sends out a confirmation ACK K+1.
Connection establishment completes, and after communication linkage, just can communicate.IP agreement is all assigned with an IP address for each client, and the IP address that to be network unique, the IP address that each client is assigned with.
S202, client receive the input instruction of user, input message to be sent, and message to be sent is encrypted for encryption key according to the pet name first in the user profile of rear four and the client of the IP address of client, obtain the encrypting messages of message to be sent.
When client need send message to selected good friend's client, need first input message to be sent.Now, if be not encrypted message to be sent, then likely obtained by other client illicit interception, Information Security is lower.Therefore the present invention in the specific implementation, adopt and for encryption key, message to be sent is encrypted with the pet name first in the user profile of rear four and the client of the IP address of client, obtain the encrypting messages of message to be sent, to improve Information Security.Preferably, described message to be sent comprises packet header, good friend's pet name, identifying code and chat content information.
