It is real below in order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand Apply example combination attached drawing to the composition of long connection network data distribution and processing method and system in the IOS systems of the present invention, structure, Connection relation, specific workflow and operation principle, effect and effect, which are specifically described, to be specifically addressed.
Below in the network direct broadcasting in background technology, direct broadcast server carries out long connection by network communication to client (long connection, multiple data packets can be continuously transmitted at one in connection by referring to, during connecting holding, if sent out without data packet Send, both sides needed to send out link detecting packet) it is described in detail the case where sending network data.
Embodiment 1
Fig. 1 is that the step of length connects network data distribution and processing method in the IOS systems in the embodiment of the present invention is shown It is intended to.
As shown in Figure 1, the network data distribution of the present embodiment and processing method have step S1-S5.
Step S1 carries out the network data of long connection using the network interface layer of C++ written in code IOS system clients Transmitting-receiving.
Fig. 2 is the transceiving step schematic diagram for the network data that network interface layer carries out long connection in the embodiment of the present invention.
The present invention be directed to mobile intelligent terminal or desktop computer IOS application programs, in order in the third of network communication Layer transport layer, second layer network layer and first layer network interface carry out the network communication of long connection, need to open using C++ codes The interface of hairnet network transceiving data, i.e., in first layer network interface using C++ code developments data-interface come in different operations It is operated between system, can both make it possible to and executed in different system platforms, while its execution can also be improved Efficiency.The transmitting-receiving for the network data that specific network interface layer carries out long connection includes the following steps:
Step S1-1 creates network socket between reception and the client and server of distribution network data.
Long linked network is carried out by writing socket programs, so firstly the need of a web socket is created socket.The specific then api function int sockfd that are provided by IOS systems:
Int sockfd=socket (AF_INET, SOCK_STREAM, 0);
To be created, wherein
Socket then indicates to create the web socket socket of a streaming.
First parameter AF_INET indicates IPv4Internet agreements.
Second parameter SOCK_STREAM indicates Tcp connections, provide serializing, reliably, the byte that is bi-directionally connected Stream.
It is 0 that third parameter, which is then filled out,.
Step S1-2, the IP address and port numbers of setting network socket.
After setting socket, client needs the IP address and port numbers of inserting server before Connection Service device It is linked, only specifies IP address and corresponding port numbers, specified server program can be linked to.
The present embodiment is to store the addresses ip and the port numbers of setting, network by defining the structure of a network address The structure of address is:
struct sockaddr_in serveraddr;
Serveraddr.sin_family=AF_INET;
Serveraddr.sin_port=port;
Serveraddr.sin_addr.s_addr=ip;
The port and ip wherein inserted is exactly the addresses ip and the port numbers of server.
Step S1-3, client are attached with server.
Start linked server.When creating socket word network socket, after filling in server address, then can go to link Server.IOS systems provide a corresponding function connect and carry out linked server.Function is as follows:
int connect(int sockfd,const struct sockaddr*addr,socklen_t addrlen);
Using the function, the client of TCP networks is connect by connect functions with server-side, is communicated, wherein Sockfd is that the network socket word network socket, Addr that create before are the IP address of the server created before, Addrlen It is the length of IP address data.
Input order in this way:
connect(sockfd,&serveraddr,sizeof(serveraddr));
Connect functions are run, client begins to linked server.
Step S1-4 sends and receivees network data using thread function.
Server message and transmission server message are received to write program using Socket, which is that an IO is (defeated Enter output) it operates, so it will produce blocking operation, in order to which program is capable of the execution of flow, then need establishment one independent Thread function carries out transmitting-receiving operation to internet message, the corresponding api function that is provided using IOS systems in the present embodiment Pthread_create creates thread function.
The function that thread creation is carried out using api function pthread_create is as follows:
int pthread_create(pthread_t*tidp,const pthread_attr_t*restrict_attr, void*(*start_rtn)(void*),void*restrict arg);
Wherein, first parameter pthread_t*tidp is the pointer for being directed toward thread identifier, second parameter const Pthread_attr_t*restrict_attr is for thread attribute, third parameter void* (* start_rtn) is arranged (void*) be thread operation function initial address, the last one parameter void*restrict arg are active thread functions Parameter.
Fig. 3 is the step schematic diagram that the embodiment of the present invention thread function sends and receivees network data.
So important is then thread function, and the present embodiment defines a SocketRun as thread function, the thread Function sends and receivees the step of network data and includes:
Step S1-4-1, SocketRun monitor the event of network socket as thread function, by life below Code is enabled to realize:
Thread function can then write while cycles the event of socket is monitored and be handled.
Step S1-4-2, according to monitor the case where, judge that current network socket is readable using seletct functions State still can write state.
By to socket, using select functions, judge receiving the message of server by current sokcet, be in can Read states still can write state, select functions are:
Ret=Select (socket);
Judge that current socket socket is can to read by select functions, still can write.
Step S1-4-3 receives the network data that server is sent when being judged as readable state by recv functions.
If it is determined that readable state, then illustrate to have received the message that server is sent to client, just pass through recv letters It counts to receive the message of server:
recv(socket,(char*)buf,len,0);
Wherein first parameter socket is the socket created before, and second parameter (char*) buf is that storage receives The message of the server arrived, third parameter len are the length of the data received, and it is 0 that the 4th parameter, which does not use,.
Step S1-4-4, when be judged as can write state when, network data is sent to server by send functions.
If it is determined that can write state, then illustrate that current socket can send data to server, just pass through system The send functions of offer send a message to server:
send(socket,(char*)buf,(size_t)(len),0);
Wherein first parameter socket is the socket created before, and second parameter (char*) buf is to have write The data for needing to be sent to server are entered, third parameter (size_t) (len) is the length of data in buf, the 4th ginseng It is 0 that number, which does not use,.
Thread function can then write while cycles, this cycle then can constantly handle the message data for receiving server, and And server is sent data to, so far, the processing of client network data transmit-receive is achieved that by the step.
Step S2 is decrypted and unpacks to the network data received.
Server sends a message to client, for safety, needs that message is encrypted.And client exists After the message for receiving server, need that operation is decrypted to message, while after the completion of decryption, the message of outbound message can be decrypted Type, to carry out the transmission of message by type and handle in next step.
Decryption and the detailed process unpacked are:
First, it is decrypted using enciphering and deciphering algorithm TEA.
The TEA enciphering and deciphering algorithm functions of lightweight are used for internet message encryption and decryption the present embodiment:
TEA.Decrypt(encryptbuf,len);
Wherein TEA.Decrypt is the interface function of TEA ciphertext datas, and parameter encryptbuf is the net that server is sent Network data, that is, encrypted data are wanted, parameter len is the length of data.
Then, parsing operation is carried out after the completion of decryption, parses the corresponding type of message of the network data and information Content.
After the completion of decryption, de-packaging operation is carried out to message, so as to parse the type of outbound message, this message is assorted , use unpacking function unpack:
Type=unpack (encryptbuf, len);
Wherein, unpack is corresponding unpacking function, wherein the parameter encryptbuf inputted is then the clothes decrypted before Business device message, parameter len is then the length for the server message decrypted before.By type it is known that current network disappears What breath is, specifically which classification.
So far, the process that the message of server is decrypted and is parsed is achieved that by the step.
The network data that C++ layer networks receive is transmitted to the object-c code layers of application layer by step S3.
In order to be preferably managed to the distribution of message and processing, the present embodiment is write one at C++ layers and abstract is connect Mouthful, it is supplied to application layer object-c, abstraction interface then to define the interface and parameter type of PUSH message, by C++ layer networks The process that the network data received is transmitted to the object-c code layers of application layer is the call back function carried by IOS systems What callback and Push functions were realized.
Call back function callback is specifically named as ICallback, specific code is as follows:
An empty ICallback is write, to prevent RAM leakage, wherein interface name is a class, ICallback。
Define Push functions:OnPush, Function Format are:
Virtual void OnPush (const char*type, const char*message)=0;
}
A pure virtual function OnPush is defined, is the interface function that the present embodiment is write, wherein parameter const Char*type indicates that the type of message, parameter const char*message indicate message.Re-define an interface function SetCallback is used to be arranged the specific example of this interface to object-c:
void SetCallback(ICallback*callback);
This interface function is used to the specific example of application layer setting ICallback.
And for C++ layers of bottom, for realizing that SetCallback functions store the mesh of the interface instance of application layer setting 's.
For C++ layers, the setting example that a global ICallback pointer is used to store application program is defined:
ICallback*g_callback=NULL;
Then it is configured in SetCallback.
For the data of network decrypting server and the data of resolution server write before, it is being parsed Afterwards, then this call back function callback can be called to be delivered in the code of the object-c of application layer, specific code It is as follows:
g_callback->OnPush(type,encryptbuf);
Wherein OnPush is then the interface write.
Wherein type is then the type of message.
Wherein encryptbuf be then before the network data that parses after server decryption.
To by calling the data transfer after the OnPush functions network analysis that receives C++ layers to application layer Object-c code layers.
So far, it is achieved that by the step and the net that corresponding interface code receives bottom is write by using C++ Network message data is transmitted in the object-c code layers of application layer.
Network data is pushed to by object-c code layers in the application layer of IOS by step S4.
After network data is pushed to the application layer of IOS, application layer according to the type of information be distributed to different modules come Processing.
For application layer code, the code function for realizing corresponding interface layer is needed, that is to say and write call back function The subclass of ICallback classes, and realize that therein deposit needs Push function OnPush, to receive network data in c++ code layers Afterwards, can be by the OnPush interface codes of calling application layer, it will be in network data transmitting to application layer.
The code for writing the subclass of call back function ICallback classes is:
class CNetCallback public:ICallback
Wherein, CNetCallback is inherited from ICallback, and code is:
{
public:
Interface void OnPush (const char*type, const char*message)
Wherein CNetCallback classes must satisfy the function of realizing OnPush interfaces, in this way in bottom C++ code calls When, what is actually called is then the OnPush interfaces for this CNetCallback class that application layer is write, in this way, being achieved that C+ + data transfer to the object-c code layers of IOS application layers in.
In this OnPush interface function, application layer then can carry out the distribution of message according to the type type of message, I.e. application layer is distributed to different modules to handle according to the type of information.
In the present embodiment, the client is network direct broadcasting client, and the server is network direct broadcasting server, institute In the case of application layer is stated as network direct broadcasting platform, the code write is:If (type==" danmu ")
If type of message is " danmu " barrage message, the barrage display area that barrage is put into application layer is shown Show.
Else if (type==" gift ")
If type of message is " gift " present message, present is shown to the present region of application layer.
Else if (type==" voicelink ")
If type of message is " voicelink " even wheat message, application layer pop-up even wheat setting starts even wheat function.
}
Particularly as being:
When type of message is barrage type, the barrage display area which can be put into application layer by application layer is shown Show,
When type of message is present type, the present display area which can be put into application layer by application layer is shown Show,
When type of message is even wheat type, application layer can the setting of company of pop-up wheat, start company's wheat function.
By above process, after network data is pushed to the application layer of IOS, application layer is distributed according to the type of information It is handled to different modules, in this way, application layer only needs to write the code of the distribution realization of type of message and application program is wanted The respective code of the type of message of processing, and received message, decryption message are then all realized by C++ bottom codes, total As a result it is exactly that the development process of IOS application layers is made to become simple, improved efficiency, and without concern third layer transport layer, second The realization process of layer network layer so that the written in code of the client of IOS systems and the network data distribution procedure of server becomes Simply, without going to consider the problems of how network socket etc. realize in network layer and transport layer.
As a kind of optimization to the present embodiment, in step s 2, when C++ layer networks receive the message of server and right After message has carried out decryption and de-packaging operation, in order to cope with situations such as server being likely to occur does not connect or breaks, meeting There are a judgment step, the content of the network data to decrypting judges:
When the content of message is server mistake, then network socket can carry out network reconnection;
When the content of message is other content, then answering for IOS is pushed to via the object-c code layers of application layer With in layer.
That is, if message content is " server mistake ", the Socket of C++ can carry out network reconnection, otherwise If it is other contents, the code that can be pushed to the object-c of application layer goes to handle and show, e.g. barrage message, The barrage display area that barrage is just put into application layer is shown.
