Abstract
The invention discloses the communication means of a kind of client based on socket and server-side, steps are as follows: the listening thread for starting server-side monitors specified port numbers, while starting detection thread；Client creates socket, is connected to specified services end；After both sides establish connection, client numbers the unique client of oneself, is sent to server-side；After server-side receives client number, by client number, client ip address, client end slogan and the time preservation for receiving client data；According to the circulation time of setting, thread is detected to client address and sends detection information；After client receives detection information, client is returned immediately and is numbered to server-side；Server-side numbers the data for updating and saving in server-side according to the client of return.The present invention is because there is client number, and orientable which client determine connection be.Can know that specifically which client there is a problem when a problem occurs, be accurately positioned, solves rapid.
Description
Technical field
The present invention relates to field of communication technology, specifically a kind of client and server-side based on communication keeps the side of connection
Method.
Background technique
Socket (socket) is the intervening software abstraction layer of application layer and TCP/IP protocol suite communication, is that its one group connects
Mouthful.Comprising carrying out the necessary information of network communication.
Multiple TCP connections or multiple program process may be needed through the same Transmission Control Protocol port transmission data,
In order to distinguish different program process and connection, operating system provides for application program and TPC/IP protocol interaction
socket.Application layer and transport layer can be distinguished logical from different application process or network connection by socket
Letter realizes the concurrent services of data transmission.
The system communicated on internet using TCP, can all face frequent disconnection, network topology is numerous and complicated
It is complicated and multiple switch, router, firewall etc. hardware device may be passed through between client to server-side, often
The related setting of a hardware device also disunity, along with congestion, the delay etc. being likely to occur in network, so that we are being handled
It is very intractable when going offline.
In order to solve delay and congestion problems, currently existing scheme is on Socket by the inspection built in ICP/IP protocol layer
Whether survey method survives to judge to connect, for example, setting detection in 2 seconds is primary, the throw exception when detection more than 10 seconds fails.Root
According to actual test, this setting can solve a part of problem, but still suffer from some connections upon opening, considerably beyond 10
Second, which is just perceived, to go offline.Moreover, that server-side can not determine connection is that visitor if the address client ip changes
Family end.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiency of the prior art, and provide it is a kind of can be accurate
Positioning and the client and server-side communication means based on socket that can promptly and accurately detect.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of communication means of client and server-side based on socket, which is characterized in that step are as follows:
S1 starts the listening thread of server-side, monitors specified port numbers, while starting detection thread；
S2 client creates socket, is connected to specified services end；
After S3 both sides establish connection, client numbers the unique client of oneself, is sent to server-side；
After S4 server-side receives client number, following data is saved, data include that the client of client is compiled
Number, client ip address, client end slogan and the time for receiving client data；
S5 is according to the circulation time of setting, and the data that detection thread taking-up saves, send to client address and client is arranged
Good detection information；
After S6 client receives detection information, client is returned immediately and is numbered to server-side；
S7 server-side receives the client number of return, and the data for updating and saving in server-side are numbered according to the client of return.
The circulation time that detection thread is set, detection thread was sent according to the circulation time of setting to client as 5-60 seconds
One-time detection information.
The detection information is { action:1;Model:1 }).
The time of detection thread loops can freely set according to the actual situation, such as set 5 seconds circulation primaries, then detect thread
Every five seconds sends a data to client.
If some client there is a problem, the corresponding data of the client (time) cannot be more in database
Newly, it is easy to judge whether go offline.At this moment technical staff, which can be contacted, goes to given client end to check problem.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
1. because there is client number, orientable which client determine connection be.It can know that when a problem occurs
Specifically which client there is a problem, be accurately positioned, and solve rapid.
2. detection time in time, accurately, is not in the phenomenon that being not detected after connection disconnects.
3. being not necessarily limited the ip and port numbers of client, more flexibly.
4. the time of cycle detection freely configures, it is applicable in various occasions.
Detailed description of the invention
Fig. 1 is the flow diagram of communication means of the present invention.
Specific embodiment
With reference to the accompanying drawing, it elaborates to the present invention:
The present invention is based on the communication means of the client of socket and server-side, detailed process is as follows:
S5 starts the listening thread of server-side, monitors specified port numbers (such as 8543), while starting detection thread；
S2 client creates socket, is connected to specified services end, such as (127.0.0.1:8543)
After S3 both sides establish connection, client oneself number (unique encodings that client and server-side have been appointed, such as
({ code:10001 }), is sent to server-side.
After S4 server-side receives data, the number of client, IP address, port numbers receive the time guarantor of data
It stores away (such as: { code:10001;ip:192.168.30.86:1230;Time:2019-01-18 09:00:00 }).
S5 detects thread and takes out the data saved, sends detection information (as sent { action:1 to client address;
Model:1 }).
S6 client (such as has received { action:1 after receiving detection information;Model:1 }), it returns message to immediately
Server-side (such as { code:10001 }).
S7 server-side, which receives, returns to message ({ code:10001 }), according to returning to message, the information in more new database, such as
({ code:10001;ip:192.168.30.86:1230;Time:2019-01-18 09:00:05 }).
The time of detection thread loops can freely set according to the actual situation (as set 5 seconds circulation primaries, then detects thread
Every five seconds sends a data, general setting 5-60 seconds or so to client), the step of S5-S7 is repeated according to the time of setting later
Suddenly.
If a certain client do not replied for a long time (it is time that such as 10001 client last time, which receive the time of information:
2019-01-18 09:00:00, now 2019-01-18 09:00:30), then it is assumed that connection there is a problem, the client
End has gone offline, and will send a warning message to technical staff (such as: short message push).At this moment technical staff can go to given client end
Check problem.
