Protection scope within.
PHP (Hypertext Preprocessor, HyperText Preprocessor) is a kind of general open source scripting language, is inhaled
The characteristics of having received C language, Java and Perl is conducive to study, using extensive.The unique grammer of PHP be mixed with C language, Java,
Perl and PHP can more quickly perform dynamic web page than CGI or Perl from the grammer of wound；With other programming languages
It compares, PHP is to be embedded into program in HTML (application under standard generalized markup language) document to go to execute, execution efficiency
CGI than generating HTML markup completely is many higher；PHP can also be performed compiled code, and compiling can achieve encryption and excellent
Change code operation, makes code operation faster.Due to these advantages of PHP, PHP is used in the equipment such as server.It is existing
When communicating with destination server, PHP server and destination server pass through TCP for a kind of application PHP server
(Transmission Control Protocol, transmission control protocol) agreement establishes a communication connection, and data are sent completely
Afterwards, this communication connection is just disconnected.However, PHP server with destination server when being communicated, it may be necessary to repeatedly be counted
According to transmission, so that PHP server need to repeatedly establish communication connection with destination server, Internet resources are wasted, reduce PHP clothes
The stability of business device.The stability of PHP server can be improved in data transmission method provided by the present application.
The application provides a kind of data transmission method, is applied to PHP server.
Referring to Fig.1, Fig. 1 is the flow diagram of the application first embodiment.
In the first embodiment, this method may comprise steps of:
Step S101: using the long connection between destination server pre-established, data are sent to destination server
Request.
In practical application, PHP server can be first with the long connection between destination server pre-established, to mesh
Mark server send request of data so that destination server respond the request of data and obtain PHP server needed for data.
The time and mode that long connection is established between PHP server and destination server can be determine according to actual needs.
Step S102: the data that destination server is sent are received using long connection.
In practical application, PHP server is after being sent to destination server for request of data using long connection, target clothes
Business device can search data corresponding with the request of data, and the data found are sent to PHP service by length connection
Device, correspondingly, the long connection of PHP server by utilizing receives the data that destination server is sent.
A kind of data transmission method provided by the present application is applied to PHP server, utilizes pre-establish and destination service
Long connection between device, sends request of data to destination server；Utilize the long data for connecting and receiving destination server and sending.This
A kind of data transmission method provided is provided, the length between destination server that PHP server by utilizing pre-establishes connects, to
Destination server sends request of data, and receives the data namely PHP server and mesh that destination server is sent using long connection
Data are exchanged by long connection between mark server, it, can repeatedly and target in this way after PHP server establishes vice-minister connection
Server is communicated, and compared with prior art, reduces the number that PHP server disconnected, re-established connection, is improved
The stability of PHP server.
In the first embodiment, the condition that PHP server pre-establishes the long connection between destination server can basis
Actual needs determines, for example can periodically establish length connection, and length connection etc., concrete application field are established under extraneous control
Jing Zhong, PHP server send data to destination server and ask using the long connection between destination server pre-established
Before asking, long it can also be connected when needing to destination server request data, establish between destination server.Namely
PHP resettles the long connection between destination server when needing to destination server request data, correspondingly, the external world can lead to
Cross to the instruction that PHP server is sent to destination server request data and give PFP server, with control PHP server establish with
Long connection between destination server etc..
In the first embodiment, it establishes for the ease of PHP server and is connected the length between destination server, and in order to just
It can establish when length of the PHP server between foundation and destination server connects in management of the PHP server to long connection
Long connection middleware；Establish the long connection between long connection middleware and destination server.Namely PHP server is creating itself
Long connection middleware, and the length established between long connection middleware and destination server connects, in this way, subsequent PHP server exists
When needing to communicate with destination server, length connection middleware can be called directly and communicated with destination server, and
When not needing to keep be long and connecting, can directly destroy length connection middleware and then disconnect long connection namely PHP server can be with
By long connection Middleware implementation to the centralized management of long connection.
In concrete application scene, PHP server is connected using the length between destination server pre-established, to mesh
When marking server transmission request of data, request of data can be sent to long connection middleware, so that the long middleware that connects is using length
It connects to destination server and sends request of data；It, can be with correspondingly, when receiving the data that destination server is sent using long connection
Receive the data from destination server of long connection middleware forwarding.
In concrete application scene, PHP server can be according to practical need in the type of the long connection middleware itself created
It flexibly to determine, for example the type of long connection middleware can be the process etc. in PHP server, then PHP server is being established
When long connection middleware, the long connection middleware that type is process can establish；Correspondingly, sending number to long connection middleware
When according to request, request of data can be sent to long connection middleware by Unix domain socket agreement.It can certainly
Request of data etc. is sent to long connection middleware by port numbers agreement.
In the first embodiment, in order to improve the stability of PHP server, PHP server can keep long connection to continue
In connected state, in addition, being easy to appear disconnection after the long connection between PHP server and destination server continues for some time
The case where, it is based on such situation, in order to guarantee that long connection is continuously in connected state, and is kept to mitigate PHP server
Long junction in the service pressure of connected state, PHP server using long connection receive data that destination server is sent it
Afterwards, the accumulation duration not carried out data transmission between destination server can also be accumulated；Judge to accumulate whether duration is more than or equal to
Preset duration；If so, send detection data packet to destination server, and the transmission result judgement based on detection data packet is long connects
It connects and whether is in an off state, if long junction re-establishes long connection in off-state.Preset duration and detection data packet
Can flexibly it determine according to actual needs.
On the other hand, the application provides a kind of data transmission system, is applied to PHP server.
