Abstract
The invention provides a network message passing method which comprises a server and a plurality of clients, wherein the server is in interactive connection with each client; the server monitors all client ports and determines whether a client request exists or not, if the client request exists, data of a sending end is received, and messages extracted from the data are sent to a receiving end; and the clients are used for sending and receiving data, when the data is received, whether the data in a package is that required by a user is determined according to information content, if yes, the data is processed according to information types, and otherwise, the data is abandoned automatically. Compared with the prior art, the plurality of clients are connected to the server, and then the messages are transmitted through the server internet, so that safety and reliability of data passing are guaranteed, and the network message passing method is easy to popularize.
Description
Technical field
The present invention relates to a kind of ICT (information and communication technology) field, specifically a kind of fail safe, reliability that has guaranteed that data are transmitted by connecting the clients to service end, passed through a kind of method of network delivery message by service end.
Background technology
Along with data interaction between the present software becomes more and more frequent, each data interaction all needs to write the data-interface program and could realize, does not have a kind of special software service method can be for carrying out data interaction between a plurality of softwares.The software of data interaction is a lot of if desired, and data interaction will be very loaded down with trivial details so, is inconvenient to operate; in addition; fail safe and the reliability of data can't be protected when carrying out data interaction between the mutual software of general data and transmitting, thereby cause loss of data easily, are difficult for promoting.
Summary of the invention
Technical assignment of the present invention is in the deficiencies in the prior art, and a kind of internet message transmission method that guarantees the data interaction fail safe is provided.
Technical scheme of the present invention realizes that in the following manner this a kind of internet message transmission method comprises server end and some clients,
Described server end all is connected alternately with each client, and this server end is monitored all client ports, and judges whether the request of client, if having then the data of receiving end/sending end, the message that extracting data is gone out sends to receiving terminal;
Described client is used for sending data and receives data, judges according to the information content whether these bag data are data of own needs when receiving data, if handle according to information type, if not then losing automatically.
Described server end comprises the destination address that sends from transmitting terminal and message header, information type port numbers from the extracting data outbound message.
The service request that described server end is monitored client at each port refers to, service processes is in resting state always, up to there being a client that this service has been proposed connection request, service thread " was waken up " also and was created a thread separately for client this moment, set up the virtual interface channel of a special use, finish the exchange of data by tunnel.
Described " waking up " process refers to: server end is opened a listening port, be responsible for monitoring the request of client, send the reception circulation with server and take out each client process successively from accepting formation, connect the back and generate new port, create this client of subprocess special disposal then, parent process is then closed new port, continues to handle next client process; And the port of server monitoring usefulness is useless to subprocess, so subprocess is closed it, with the new port and the customer interaction information that produce, closes this connection up to the other side, and subprocess stops.
The data that above-mentioned server receives client at first are saved in the internal memory stream, come segmentation to send data according to the spatial cache size then, till sending, empty internal memory stream again, wait for that send next time; Equally, when client computer receives, judge the size of the stream that receives, if the size of stream is less than or equal to the spatial cache size, then sends and continue that server continues to send the spatial cache size, the client computer circulation receives, till having passed.
The beneficial effect that the present invention compared with prior art produces is:
A kind of internet message transmission method of the present invention is connected to server end with a plurality of clients, and then carry out pass-along message by the server end network, fail safe and reliability that data are transmitted have been guaranteed, the client of mutual some band interactive softwares simultaneously, data exchange process is simple, and is easy to operate.
Description of drawings
Accompanying drawing 1 is structural representation block diagram of the present invention.
Accompanying drawing 2 is realization flow schematic diagrames of the present invention.
Embodiment
Below in conjunction with accompanying drawing a kind of internet message transmission method provided by the present invention is done following detailed description the in detail.
The present invention is primarily aimed at the situation of data interaction inconvenience between a plurality of softwares, and a kind of internet message transmission method based on port communication is provided, and is used for finishing quickly and easily mutual between the data.The present invention includes server end and some clients, structure chart as shown in Figure 1, wherein said server end all is connected alternately with each client, this server end is monitored all client ports, and judge whether the request of client, if have then receive the data of transmit leg, the destination address that sends from the extracting data outbound message and message header, information type port numbers send to data the data receiving software then.
Described client is used for sending data and receives data, judges according to message header or port numbers whether these bag data are data of own needs when receiving data, if handle according to information type, if not then losing automatically.
Server-side application is in the request of a port monitoring to service, that is to say that service processes is in resting state always, up to there being a client that this service has been proposed connection request, service thread " was waken up " also and was created a thread separately for client this moment, set up the virtual interface channel of a special use, finish the exchange of data by tunnel.
To read data not blocked for client computer and server when guaranteeing a plurality of software transmission, the multi-process technology is used in this invention, when in a single day server end receives the request of client, just build an independent process for using the family instead specially, carry out the visit interactive operation of data.
Its concrete data transfer as shown in Figure 2, server end is opened a listening port, be responsible for monitoring the request of client, send the reception circulation with server and take out each client process successively from accepting formation, connect the back and generate new port, create this client of subprocess special disposal then, parent process is then closed new port, continues to handle next client process; And the port of server monitoring usefulness is useless to subprocess, so subprocess is closed it, with the new port and the customer interaction information that produce, closes this connection up to the other side, and subprocess stops.
The data that above-mentioned server receives client at first are saved in the internal memory stream, come segmentation to send data according to the spatial cache size then, till sending, empty internal memory stream again, wait for that send next time; Equally, when client computer receives, judge the size of the stream that receives, if the size of stream is less than or equal to the spatial cache size, then sends and continue that server continues to send the spatial cache size, the client computer circulation receives, till having passed.
The number of connection of server end and client is dynamic, follows a new client-requested, and it is corresponding with this client to produce a new port, carries out independent communication.
