Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The remote service calling method that the present invention is provided is applied in client, and client is configured with multiple connection pools, each
Connection pool is each corresponding with a server.It is to be appreciated that the present invention is provided with multiple servers, each server can be achieved
The call request of service calling module.That is, being backuped each other between multiple servers, the negative of service invocation request is realized
Carry balanced.Compared to the call request of application program is realized into module is integrated in for a computer in the prior art, this reality
The stability and security of service call can be improved by applying example.
The system architecture of client and multiple servers based on above-mentioned offer, the embodiments of the invention provide a kind of long-range
Service calling method.Referring to Fig. 1, it illustrates the flow of this method, the flow is specifically included：
Step S101：When receiving the service invocation request of service calling module transmission, in multiple servers,
It is determined that idle destination server.
Wherein, service calling module is a module in client application, when the module needs to call long-range clothes
During module of being engaged in, service invocation request is generated, wherein, the title and ginseng of the service in need called are included in service invocation request
Number.Service invocation request is sent to the executive agent of this method, asked when the executive agent of this method receives the service call
, it is necessary in multiple servers of setting, search a server for being currently at idle condition, be defined as destination service when asking
Device.
Step S102：In the corresponding connection pool of the destination server, idle target length connection is obtained.
Wherein, client is provided with multiple connection pools, each server is corresponding with a connection pool.And each connection
Initialization has multiple long connections in pond.It is determined that the corresponding connection pool of destination server in, search one be currently at sky
The long connection of not busy state, for sending service invocation request to the destination server.It is to be appreciated that idle long connection, refers to
It is that length connection does not take transmission service invocation request by other arbitrary service calling modules.
Step S103：When the target length is connected as effective status, connected using the target length, the service is adjusted
With request send to the destination server, trigger the destination server and call clothes corresponding with the service invocation request
Business, the call result is returned to obtain call result, and trigger the destination server.
Wherein, if network or server break down, target length can be caused to be connected to become down state.In order to improve
The success rate of service invocation request, before service invocation request is sent, it is thus necessary to determine that whether long connection is in effective status.When
When the connection of target length is in effective status, connected using the target length, send service invocation request.Specifically, detection target is long
Whether the method in effective status can be for connection, connected using the target length to destination server and send detection packet,
Assuming that receiving the reply of destination server, determine that target length connection is in effective status.
In the present embodiment, exist before service invocation request is sent, it is necessary to which service invocation request is carried out into serializing post package
In packet, then using the connection of target length, the packet is sent to destination server.Service is provided with destination server
Component is held, after the service end component of destination server receives service invocation request, service invocation procedure is realized, is serviced
Call result.
Specifically, the packet after above-mentioned serializing is carried out unserializing processing by destination server, is obtained needs and is called
Service title and parameter, find corresponding service execution module according to the service name, trigger the service execution module
Service call is performed, call result is obtained, the present embodiment is back to by long connection after the call result is serialized
Executive agent.
Step S104：The call result is sent to the service calling module.
Wherein, the executive agent of the present embodiment is received after the call result, and call result is carried out after unserializing, hair
The service calling module for sending service invocation request is delivered to, service invocation procedure is completed.
Technical scheme more than, the remote service calling method that this implementation is provided, is applied in client, client
Multiple connection pools are provided with, each connection pool is corresponding with a server, multiple servers of setting can complete service and adjust
With process, therefore, before service invocation request is sent, an idle server can be determined in multiple servers of setting.
Compared with only a mode to realize service call is set in the prior art, the set-up mode enhancing of multiple server backups
The stability and security of service call.
Meanwhile, initialization has multiple long connections in connection pool, is sent service invocation request to determining using long connection
Destination server.However, in the prior art, the connection with destination server is realized using short connection.If using short connection,
Client is needed to send before service invocation request to server every time, is required to create short connection, and service call is completed every time
Afterwards, it is necessary to close short connection.So, short connection is created every time to be both needed to expend system resource, overhead is larger, also, can make
Into the delay of service call.The present embodiment client carries out data interaction using long connection and server, because long connection is to begin
The connection communicated is kept with server eventually, unless server end disconnects the connection for various reasons, therefore, client passes through wound
Build vice-minister connection, you can repeatedly send service invocation request using length connection, overhead is smaller, and service call efficiency
It is higher.
In the prior art, client have services cache function, i.e. client can by service execution module (or be referred to as
Service implementation) memory address to be buffered in client local, when client receives the service call of service calling module
After request, first in the local memory address for searching service, and the memory address found is included in the service call generated
In request, server is sent to, the server direct basis memory address determines position of the service execution module in internal memory, entered
And trigger service execution module and realize service invocation procedure.However, services cache method of the prior art, in the clothes of server
After the memory address of business performing module is changed, the invalid of service invocation request can be caused, and then cause the mistake of service call
Lose.
Unlike, in the present embodiment, service name and service parameter are only included in the service invocation request received,
Do not include the memory address of service execution module, but the service invocation request is sent to server, server foundation
The service name and the corresponding relation of the memory address of service execution module pre-set, it is determined that needing the service name pair called
The memory address for the service execution module answered.After being changed due to the memory address of service execution module, server can be therewith
Change the corresponding relation of memory address and service name, therefore, the remote service calling method that the present embodiment is provided be it is dynamic,
That is, being not rely on the memory address for being stored in advance in local service execution module, and then existing skill can be avoided
Service call failure scenario caused by the memory address of service execution module is prestored in art.
It is to be appreciated that in the above-described embodiments, the concrete mode that client configures multiple servers, which is that record is each, to be serviced
The port numbers of the IP address of device and each server process service invocation request.In addition, server is provided with service execution module,
Server calls service execution module obtains service call result to realize service invocation request.Service execution module is in service
Address in device internal memory needs to be registered in server operating component, and registration process is by the title of service and service execution mould
The memory address of block sets up corresponding relation, so, and server is received after service invocation request, according in service invocation request
Service name and the corresponding relation of foundation, it may be determined that the memory address of service execution module, and then find service execution mould
The core position of block, realizes service invocation procedure.
Alternatively, the step S101 in above-described embodiment is in multiple servers, it is determined that idle destination server
Specific implementation can be：Using polling algorithm, in multiple servers, it is determined that idle destination server.
Specifically, polling algorithm refers to judging whether each destination server is in idle condition successively.Assuming that multiple
The mark of server is stored in queue, is obtained first server identification from row are first, is judged the corresponding service of the server identification
Whether device is in idle condition, if so, the corresponding server of server identification that this gets then is defined as destination server,
Otherwise, the server identification got is put into the tail of the queue of queue, next server identification is obtained from head of the queue successively, repetition is obtained
The step of taking, until getting the server of free time.If the corresponding server of whole server identifications preserved in queue is not
In idle condition, the service invocation request is set to wait for whether leisure service occur in state, and real-time judge queue
Device, when occur in queue free time server after, will the idle server be defined as destination server.
Certainly, the mode that the present invention does not limit determination idle server is to utilize polling algorithm, can also utilize weight
Algorithm, that is, pre-set the weighted value of each server, will be currently at the maximum clothes of weighted value in the server of idle condition
Business device is defined as destination server.
Fig. 2 is referred to, it illustrates another flow of remote service calling method provided in an embodiment of the present invention.It is optional
Ground, the mark of destination server device can be stored in storehouse, therefore, and step S101 is in multiple servers, it is determined that empty
The specific implementation of not busy destination server can be step S201：When the service call for receiving service calling module transmission
During request, in the first storehouse pre-set, it is determined that idle destination server；Wherein, include in first storehouse
Multiple destination servers.
In addition, understanding in the above description, the connection of target length is likely to occur abnormality, now shows that client can not
It is normally carried out communicating with destination server, therefore, sees Fig. 2, on the basis of the remote service calling method that above-described embodiment is provided,

Step S205：When the target length is connected as abnormality, the destination server is moved to from the first storehouse
In the second storehouse pre-set.
In the present embodiment, two storehouses are previously provided with, the first storehouse is used to store the normal server of connection, the second heap
Stack is used to store the abnormal server of connection.Therefore, when target length is connected as abnormality, it is necessary to which target length is connected into correspondence
Server be that destination server is moved to from the first storehouse in the second storehouse, thereby may be ensured that determined in the first storehouse it is empty
During not busy server, it is ensured that the idle server determined is the normal idle server of connection, and then improves service call mistake
The accuracy of journey.
Step S206：When any one length in destination server correspondence connection pool is connected as effective status, by institute
State destination server and move to first storehouse from second storehouse.
Wherein, when the state for occurring any one long connection in destination server correspondence connection pool is effective status, show
The connection of client and destination server is changed into normal condition again, therefore, and the mesh server is placed back in the first storehouse
In, it is ensured that it can be by normal call.
It is to be appreciated that when the target length is connected as abnormality, the connection for showing the destination server it is abnormal, it is necessary to
New destination server is determined for service invocation request, i.e., after step S205, can also be included：Return to step S201
In the first storehouse pre-set, it is determined that idle destination server.As can be seen that being mutual between the multiple servers set
For redundancy, the server of failure can't influence the realization of client service call request.
Alternatively, in each above-mentioned embodiment of the method in the corresponding connection pool of the destination server, the free time is obtained
What target length was connected, which implements process, to be：Using polling algorithm, in the corresponding connection pool of the destination server, obtain
Take the target length connection of free time.
Specifically, the process of polling algorithm is to judge whether multiple long connections in connection pool are in idle condition successively.
An alternative long connection in connection pool is obtained, judges whether the alternative long connection is in idle condition, if so, then that this is standby
Select long connection to be defined as the connection of target length, otherwise, obtain next alternative long connection in connection pool, repeat above-mentioned deterministic process,
Until determining that target length is connected.And then, obtain the transmission that the target length connection determined carries out service invocation request.
Certainly, obtain the mode of target length connection, can also any one mode in the prior art, the present invention do not limit
It is fixed.
, it is necessary to initialize connection pool in each above-mentioned inventive embodiments.Connection pool is initialized, is to be set up in connection pool
Long connection.Wherein, initializing the quantity of long connection can pre-set.When all long connections in connection pool are in using shape
During state, new long connection can be created at any time, the new length connection of establishment is defined as the connection of target length.
