Abstract

The invention discloses a data real-time calling method of a WEB server, which comprises the steps as follows: a trigger module is arranged in a database, and the trigger condition is that the information of a communication server is received or the time of keeping link is set to be 30s; the personnel at the seat end accesses the WEB server and sends a request by an Internet network; and the WEB server receives the request to call an event message from the database, wherein three conditions exist. According to the invention, the request data is sent once every 3s to every 30s, so that the space and data flow are saved; and when a CTI (computer telephony integration) server sends the event message to the database, the WEB server immediately sends the event message to the personnel at the seat end by the Internet network, so that the real-time property and high efficiency of the event are realized.

Description

A kind of WEB server data real-time calling method

Technical field

The present invention relates to communication technical field, particularly relate to a kind of WEB server data real-time calling method.

Background technology

Existing WEB server data calling method is, as Fig. 1: seat end uses computer to connect WEB server by Internet network, WEB server and the middle connection data storehouse of cti server; Event stores in a database by cti server, and seat end uses computer within every 3 seconds, to go data base call once by Internet network, and in 3 seconds, when there being event, WEB server is called event and waited until the 3rd second and returns seat end computer from database; When there is no event, also waiting until the 3rd second, returning without event signal;

No matter whether this kind of WEB server data calling method, have event, and within every 3 seconds, call once, flexibility is low, poor real, and the occupancy of frequency range is high, thus form cost waste.

Summary of the invention

The present invention proposes a kind of WEB server data real-time calling method, can be real-time from database, call event information;

The concrete steps of the method are:

Database is provided with trigger module, and trigger condition is that to receive the time that the information of the communication server or setting maintain link be 30 seconds;

1. seat end personnel connect WEB server by Internet network, send request;

2.WEB server receives request and removes data base call event information, point four kinds of situations:

A., within 30 second time, if database does not receive the event information that cti server sends, then, when 30 second time arrived, WEB server sends without event information by Internet network to seat end personnel;

If b. while database receives WEB server solicited message, database receives the event information that cti server sends simultaneously, and WEB server then sends event information by Internet network to seat end personnel immediately;

If after c. database receives WEB server solicited message 30-n second, 0 < n≤30, n is arbitrary value, cti server sends event information to database, and WEB server then sends event information by Internet network to seat end personnel at 30-n second;

If d. within 30 second time, database returns in event timeout or return data wrong, perform event timeout or exception, first close the long of last time and connect, stop current event, then carry out disconnection reconnecting, again accept WEB server request.

Beneficial effect of the present invention:

1. send a request msg from every 3 seconds to every 30 seconds, save space and data flow;

2., when cti server sends event information to database, WEB server then sends event information by Internet network to seat end personnel immediately, and achieve the real-time of event, efficiency is high.

Embodiment

To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.

The invention provides a kind of WEB server data real-time calling method, can be real-time from database, call event information;

The concrete steps of the method are:

1. seat end personnel connect WEB server by Internet network, send request;

Analyze below in conjunction with embodiment:

The implementation model of seat client is the mode by the long poll (long-polling) based on AJAX.

First Client end sends Ajax request to Server end, sets up long connection.The request of Server end process Client end, until there are data to need to return (having event), or wait timeout (without event), Server end will hold return data to Client.The data that Client holds treatment S erver to return, after having processed, send Ajax request to Server end again.

The method mainly consider in the design following some:

1.C language feature and advantage

C language is a kind of computer programming language.It had both had the feature of high-level language, again there is the features such as high-performance, in the execution efficiency of server programming overriding concern program, compare the language such as java, php, C directly can use Installed System Memory, the API directly calling more bottom also just makes to use C language coding flexible and efficient, and thing followed shortcoming is exactly need careful control routine quality.

2. realize http long connection server end code basic structure;

3.epoll mode is introduced

Epoll is linux kernelfor processing the poll that handle in enormous quantities has been done to improve, be the enhancing version of multiplexed I/O interface select/poll under Linux, it can significantly reduce program only have in a large amount of concurrent connection a small amount of active system CPU utilance.

Epoll is particularly suitable in the system of Large Copacity short-time duty, and because call center needs support 2000 seat Concurrency Access, we adopt epoll mechanism.

The handling process of the method is:

0. seat client logs, sends to bottom and logs in Login operation;

After seat logins successfully, perform telephony initialization Phone.init (), send long connection request (pollEvent) to bottom, set up long connection; The wherein long connection event code of seat client: phone.js

login-＞init-＞pollEvent＜-＞pushEvent-＞eventTimeout-＞login

1. bottom layer treatment request, waiting event (as ring ringing, init state initstatus etc.), if without any event after 30 seconds, returns and keeps heartbeat to connect keeplive event;

2. the propelling movement event (pushEvent) that returns of seat client process bottom, completes follow-up supervention and send long connection request pollEvent, then performs the 2nd step;

If 3. bottom returns in event timeout or return data wrong, perform event timeout or abnormal enventTimout, first close the long of last time and connect (dieEvent), stop current event, then carry out disconnection reconnecting, perform step 0;

4. exit seat client, perform and stop current event dieEvent, close long connection;

Key code is resolved and is comprised:

Mainly contain three functions, send Ajax request to bottom: pollEvent;

Treated Base returns and then sends request: pushEvent;

Process abnormal and overtime, disconnection reconnecting: eventTimeout

1. client sends request to bottom

This.xhrEvent.get () is that client sends AJAX request to bottom, in this.xhrEvent.get (), four parameters respectively: the URL of request, ask successful call back function pushEvent, failed call back function eventError and the call back function oTimeout of request timed out, time-out time is 35 seconds.Wherein eventError and oTimeout finally can call eventTimeout function.

URL form is as follows:

http://172.16.203.179：8080/hotline/requestaction/？action＝waiteve nt&accountno＝861000000&username＝2000&password＝e10adc3949ba59abbe56e0 57f20f883e&time＝1329967593287

2. bottom request is successfully adjusted back

If bottom has event to return or bottom wait timeout, will adjust back pushEvent function, this function is equivalent to the reception of long connection event.First in pushEvent, a series of inspection is carried out to return data, if return data is incorrect, calls eventTimeout function and carry out disconnection reconnecting, if data are correct, then can call corresponding event handling function according to the event difference of returning: obj_evt [newEvt.toLowerCase ()]; Wherein obj_evt is the array of call back function, and key is function name.

After finally processing bottom event, in pushEvent, again send pollEvent, send request to bottom.

3. bottom request timed out and failed readjustment

If send long connection event time-out or wrong generation, disconnection reconnecting function eventTimeout will be called.The long connection before being stopping mainly being operated in eventTimeout, again login request is sent to bottom, set up new connection, if again there is time-out or mistake in reconnect procedure, then can eject disconnection reconnecting prompting frame in seat client, shielding user operation, and then send login request, until reconnect successfully, prompting frame disappears automatically.

4, data format

The data format that long connection event returns is XML

In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
