Abstract
The invention provides a WebService service calling method. In the method, the upper limit for calling per second for each client end is agreed on between a server end and each client end for which the server end provides WebService services, each client end is provided with a plurality of calling threads to call WebService interfaces to obtain data on WebService service results from the server end, and the calling threads are limited to call the upper frequency of the WebService interfaces according to the upper calling limit times per second. Therefore, the condition that single client ends call the WebService interfaces without limitations to use a large quantity of resources of the server end so as to cause low operating efficiency of the server end can be effectively prevented, the distribution of the resources of the server end can be more balanced and reasonable and can be reasonably planned and managed, uncontrollable utilization of the resources can be avoided, and maintenance can be greatly facilitated.
Description
Technical field
The present invention relates to Web Service communication technical field, particularly a kind of Web Service service calling method.
Background technology
Web Service is the programmable applications program assembly that can conduct interviews by the Web agreement, can make the information between the website isolated can intercom mutually, share and provide data, services.What Web Service was used is upper unified, the open standard agreement (as HTTP, XML, SOAP, WSDL, UDDI etc.) of Internet, so Web Service can be used in the system platform (as Windows, Linux, Unix etc.) of any these standards of support, and can eliminate the difference existed between the heterogeneous system that uses different component models, operating system and programming language, heterogeneous system can be cooperated mutually becomes single computer network integral body and synthetic operation.Come from this, the ability that Web Service has good open versatility and highly integrates, therefore be widely used in internet communication.
Web Service can carry out inside from simple request to various service functions such as complicated business processings, and a certain Web Service service is in case after disposing, its service result data can be found and call to other Web Service application programs in the same Web Service network system, and, without the specific implementation process that can not know its Web Service service function, namely guaranteed simultaneously good operability and encapsulation property.In a Web Service network system, a side who disposes and provide Web Service service is Web Service server normally, is called as service end; A side who accepts Web Service service can be the terminal that the user uses, can be also these Web Service service result data of application and other servers of new business service externally are provided, be called as client (being also sometimes referred to as the consumption end).When Web Service service is provided, the inner deployment services function program of service end, the computing implementation procedure of providing Web Service service function mainly is provided the service function program, after deployment completes, its Web Service interface of service end external disclosure and needed parameter while calling this Web Service interface.When client obtains this Web Service service at needs, generate the Web Service interface interchange request that meets Web Service interface interchange parameter request, obtain Web Service service result data by calling Web Service interface; The implementation of calling Web Service interface is, client sends the request of Web Service interface interchange to service end, after the request of wait service end response Web Service interface interchange, operation Web Service service function computing return service are receiveed the response, and then the client analysis service is receiveed the response and obtained needed Web Service service result data.
In order to improve the execution efficiency of client, current client is nearly all to call Web Service interface by the mode of multithreading, be that client is provided with a plurality of invokes thread, each invokes thread can independently be carried out Web Service interface interchange and process, but and different invokes thread parallel running, so just in section, call more frequently Web Service interface at one time, in order to complete the multi-task.But the raising of client call efficiency, but to service end, brought larger operating pressure, because the Web Service interface of service end is wide-open, to client call frequency without any restriction, but the ability of service end carrying Web Service interface interchange is limited, thereby the problem that often there will be two aspects: first, the set number of threads of one or several client of service end is more and to call frequency higher if be connected to, easily make the Web Service interface of service end almost by this one or several client " monopolization ", be called, thereby may cause other to call the client call Web Service interface that frequency is lower and occur that on the contrary time delay is long even without situations such as responses, second, service end may take because processing other affairs the system resource of himself, when the occupancy of service end system resource already in higher situation, service end calculation process ability descends and then makes the ability of carrying Web Service interface interchange descend, if the part client is the calling Web Service interface of high frequency and further increase the system loading of service end still, call Web Service interface time delay, can be more serious without situations such as responses.Above-mentioned two aspect problems, make the resource of calling of service end Web Service interface distribute uncontrollable state that is in, and brought difficulty for resource management and the maintenance of service end; Simultaneously, obtain the situation of Web Service service without response, for some client platforms of applying these Web Service service result data and providing promptness service be unallowed (for example, for the client platform that obtains business data and analyzed, obtain the Web Service service of business data without response, probably cause analyzing and unsuccessfully miss business opportunity; Perhaps, for utilizing business datum to the user, to be provided at the client platform of line service service, obtain the Web Service service of business datum without response, can make user's experience sense reduce and cause customer resources to run off; Etc.).
Summary of the invention
For above shortcomings in prior art, the invention provides a kind of Web Service service calling method, avoid single client to call " monopolization " of service end Web Service interface, and then cause the long-time situation without response of other client call Web Service interface.
For achieving the above object, the present invention has adopted following technological means:
A kind of Web Service service calling method, is characterized in that, the per second that each client is provided between service end and its each client that provides Web Service to serve calls upper limit number of times; Each client is provided with a plurality of invokes thread and calls Web Service interface from service end acquisition Web Service service result data, and according to its per second, calls upper limit number of times and limit the upper limiting frequency that its a plurality of invokes thread are called Web Service interface.
Further, in said method, it is described that " each client is provided with a plurality of invokes thread and calls Web Service interface from service end acquisition Web Service service result data, and according to its per second, call upper limit number of times and limit the upper limiting frequency that its a plurality of invokes thread are called Web Service interface " be specially, each client is respectively arranged with a plurality of invokes thread, and be respectively arranged with the call number counter and move the invokes thread counter, it is 0 that the count value of described call number counter automatically reset at interval of 1 second, the count value initial condition of described operation invokes thread counter is 0, each client by its separately Web Service interface interchange request queue to be sent form request queue separately, Web Service interface interchange request in a plurality of invokes thread read request queues of client is also carried out Web Service interface interchange and is processed, thereby obtains Web Service service result data from service end,
Wherein, each invokes thread of any client is called Web Service interface as follows:
1) count value of judgement current time call number counter, call upper limit number of times S if its count value equals the per second of service end and this client agreement, performs step 2); If its count value is less than S, perform step 3);
2) this invokes thread dormancy is 1 second, then returns to execution step 1);
3) count value of call number counter adds 1, the count value of operation invokes thread counter adds 1, then this invokes thread is from reading out the most forward Web Service interface interchange request of queuing request queue, carrying out Web Service interface interchange processes, and the execution duration of calling Web Service interface is carried out to timing, until call Web Service interface, be finished, remember that it is T that this invokes thread is this time called the execution duration of Web Service interface, if carry out duration T, be less than or equal to 1/S second, perform step 4); Otherwise, this invokes thread execution step 5);
4) count value of operation invokes thread counter subtracts 1, and then this invokes thread dormancy (1/S-T) second returns to execution step 1);
5) count value that records current time operation invokes thread counter is N, and the count value of then moving the invokes thread counter subtracts 1, this invokes thread dormancy X second, X (0, T/N] between random value, then return to execution step 1).
Further, in step 5), described X (0, T/N] between the probability of random value be normal distribution.
Than prior art, the present invention has following beneficial effect:
1, the inventive method is called upper limit number of times by each client and service end agreement per second, and limit the upper limiting frequency of each client call Web Service interface with this, effectively prevented single client from unrestrictedly calling Web Service interface and taken in a large number the situation appearance that the service end resource causes the service end operational efficiency to reduce, having made the service end resource distribute more balanced, reasonable;
2, per second calls upper limit number of times and is limited voluntarily and managed by client, makes to call the frequency management task and be dispersed, and has removed the call trouble that upper limiting frequency carry out loaded down with trivial details management of service end to each client from, is conducive to reduce the operating cost of service end;
3, service end is called upper limit number of times by the different per second of the agreement of the client from different, can reasonably plan and manage its resource distribution, thereby avoids the appearance of the uncontrollable situation of the utilization of resources, convenient maintenance;
If 4 service ends are former thereby overall operation efficiency reduction because of certain, the execution duration that causes each invokes thread of client to call Web Service interface extends, adopt the client of the inventive method operation namely can self adaptation reduce the frequency of calling to Web Service interface after the invokes thread operation is saturated, alleviate the load that calls of Web Service interface, the helping service end recovers normal operational efficiency, solves service end and because operational efficiency is too low, causes the problem of client call Web Service interface without response.
The accompanying drawing explanation
Fig. 1 is the structural representation of the Web Service network system in the embodiment of the present invention;
Fig. 2 is the FB(flow block) that in the inventive method, each invokes thread of client is called Web Service interface.
Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is further described.
In prior art, because calling Web Service interface, do not limited the multithreading to client, and the Web Service interface of service end is wide-open, thereby be easy to concentrate and call Web Service interface within a period of time because of one or several client, the calling task that makes service end Web Service interface carry within a period of time is overweight, and can't respond in time the Web Service interface interchange request of other clients, cause other client calls Web Service interface delay long even without situations such as responses.For this reason, the present invention proposes a kind of Web Service service calling method, allow the per second that each client is provided between service end and its each client that provides Web Service to serve call upper limit number of times, each client is when calling Web Service interface by a plurality of invokes thread, according to its per second, call upper limit number of times and limit the upper limiting frequency that its a plurality of invokes thread are called Web Service interface, avoid thus one or several client unconfined concentrate within a period of time call Web Service interface and form " monopolization " and call, make the Web Service Service Source that service end provides obtain more balanced distribution to each client.Below by embodiment, practical application of the present invention and effect are described further.
Embodiment:
The present embodiment be take a simple Web Service network system and is example, and Web Service service calling method of the present invention is illustrated.As shown in Figure 1, in this Web Service network system, it is a Web Service server that the service end of Web Service service is provided, this Web Service server receives six different clients calling its Web Service interface of automatic network, six clients are all these Web Service service result data of application and the business platform server of new business service externally is provided, be respectively business platform server A ~ F, and these six clients adopt all the mode of multithreading to call Web Service interface.
Because the disposal ability of Web Service server is limited, suppose that Web Service server per second under up-time efficiency can carry Web Service interface interchange 10K time, K is positive integer, if adopt existing Web Service service calling method, if business platform server A is provided with 100K invokes thread and calls together Web Service interface at synchronization, this 100K time Web Service interface interchange will be queued up and continue in service end and be carried out 10 second time, within this 10 second time, because the Web Service interface of service end is called by business platform server A " monopolization ", other business platform server is again called Web Service interface and all can not be responded in time, must queue up after 100K Web Service interface interchange waiting until business platform server A finished dealing with and can be responded and process.Clearly, the Web Service service resource allocation that service end provides is unbalanced, and business platform server A concentrates and calls the interests that Web Service interface has damaged business platform server B ~ F, also is unfavorable for the resource management of service end.
Now adopt Web Service service calling method of the present invention, as the Web Service server of service end respectively and between business platform server A ~ F the per second of each business platform server of agreement call upper limit number of times; And for business platform server A ~ F, no matter the invokes thread quantity of its setting is how many, all according to its per second, calls upper limit number of times and limits the upper limiting frequency that its a plurality of invokes thread are called Web Service interface.Each client per second calls the value of upper limit number of times, can specifically according to system handling property, the service end of service end, determine the situations such as regulatory requirement of system resource; Therefore, the per second of each client calls upper limit number of times can be consistent with each other, also can be different.For example, in the present embodiment, the per second that can arrange business platform server A calls upper limit number of times S
A=4K, the per second of business platform server B call upper limit number of times S
B=2K, the per second of business platform server C call upper limit number of times S
C=K, the per second of business platform server D call upper limit number of times S
D=2, the per second of business platform server E calls upper limit number of times S
E=K, the per second of business platform server F call upper limit number of times S
F=K.And per second calls upper limit number of times, a plurality of invokes thread being called to the restriction of the upper limiting frequency of Web Service interface, is by each invokes thread of client, the special method of calling of Web Service interface to be realized in the methods of the invention.In the specific implementation, each client is provided with call number counter and operation invokes thread counter, and it is 0 that the count value of call number counter automatically reset at interval of 1 second, and the count value initial condition of operation invokes thread counter is 0; Each client by its separately Web Service interface interchange request queue to be sent form request queue separately, Web Service interface interchange request in a plurality of invokes thread read request queues of client is also carried out Web Service interface interchange and is processed, thereby obtains Web Service service result data from service end; Wherein, each invokes thread of any client is called Web Service interface as follows:
1) count value of judgement current time call number counter, call upper limit number of times S if its count value equals the per second of service end and this client agreement, performs step 2); If its count value is less than S, perform step 3);
2) this invokes thread dormancy is 1 second, then returns to execution step 1);
3) count value of call number counter adds 1, the count value of operation invokes thread counter adds 1, then this invokes thread is from reading out the most forward Web Service interface interchange request of queuing request queue, carrying out Web Service interface interchange processes, and the execution duration of calling Web Service interface is carried out to timing, until call Web Service interface, be finished, remember that it is T that this invokes thread is this time called the execution duration of Web Service interface, if carry out duration T, be less than or equal to 1/S second, perform step 4); Otherwise, this invokes thread execution step 5);
4) count value of operation invokes thread counter subtracts 1, and then this invokes thread dormancy (1/S-T) second returns to execution step 1);
5) count value that records current time operation invokes thread counter is N, and the count value of then moving the invokes thread counter subtracts 1, this invokes thread dormancy X second, X (0, T/N] between random value, then return to execution step 1).
In the present embodiment, all adopt said method to call Web Service interface as the business platform server A of client ~ F, just the per second of the business platform server A ~ F value of calling upper limit number of times S is respectively S

F.From said method, seeing, due to client by its separately Web Service interface interchange request queue to be sent form request queue separately, be equivalent to first the request of Web Service interface interchange be formed to a buffer queue client one side, and the count value of call number counter at interval of 1 second, to automatically reset be 0, while often having an invokes thread to start Web Service interface interchange process from request queue, reading out the request of a Web Service interface interchange preparation, the count value of call number counter can add 1, therefore, if reaching per second, the count value of call number counter calls upper limit number of times S, within showing in this client 1 second, called Web Service interface S time, now each invokes thread was not all restarted the operation of new Web Service interface interchange dormancy 1 second, reached and limited the purpose that a plurality of invokes thread are called Web Service interface upper limiting frequency.For example, at a time, even business platform server A prepares to carry out 100K Web Service interface interchange, but because the per second of service end and business platform server A agreement calls upper limit number of times S
A=4K, therefore business platform server A can only call upper limiting frequency 4K time with it/second the soonest, divide and completed this 100K time Web Service interface interchange in 25 seconds, and Web Service server per second under up-time efficiency can carry Web Service interface interchange 10K time, therefore other business platform server still can obtain Web Service service from service end normally, has avoided the business platform server A excessively high-frequency Web of calling Service interface and forms " monopolization " to service end Web Service Service Source.As can be seen here, the inventive method suppresses to call the client that frequency is high to be called " monopolization " of service end Web Service interface, and guaranteeing to call the client that frequency is low can normal call Web Service interface.Meanwhile, the per second of client calls upper limit number of times and is limited voluntarily and managed by client, so just will call the frequency management task has been distributed on each client individuality, this management role can't increase pressure and the cost of its system operation for each client, but for service end, but removed the trouble that upper limiting frequency is carried out loaded down with trivial details management of calling to each client from, operating cost is minimized.In addition, can see from the method running, the per second of business platform server A ~ F calls upper limit number of times S

FIn, value mean more greatly its corresponding business platform server from Web Service server system resource, be assigned to call upper limiting frequency higher, the Web Service interface interchange resource that only can be assigned to is also just more; And, S

FThe summation of value is larger, means that the load that calls of the Web Service interface bearing of Web Service server may be heavier.Therefore, service end can be called upper limit number of times by the different per second of the agreement of the client from different, reasonably plans and manages its resource and distribute, and to avoid the appearance of the uncontrollable situation of the utilization of resources, so also makes later maintenance get up more convenient.
In addition, Web Service service calling method of the present invention, also make each client possess the ability of self adaptation adjustment Web Service interface interchange frequency when the service end operation efficiency reduces, according to invokes thread, call Web Service interface and carry out the frequency that the length of duration is adjusted invokes thread startup call operation, while making the service end operation efficiency reduce, client namely can adaptive reduction after invokes thread operation is saturated to the frequency of calling of Web Service interface, to alleviate the load of service end Web Service interface, the helping service end recovers up-time efficiency, and then avoid service end because operational efficiency is too low, to cause client call Web Service interface to occur without the situation of response.Self adaptation is adjusted Web Service interface interchange frequency, is to realize according to the dormancy time that the length that the invokes thread of client is called the execution duration of Web Service interface is adjusted invokes thread.If within certain period, service end is because the load of Web Service interface interchange is overweight or taken the too much reasons such as service end system resource because processing other affairs, the Web Service service function operation efficiency of service end descends, the execution duration T that makes the single invokes thread of client call Web Service interface is greater than 1/S second (S is that the per second of client calls upper limit number of times), the system resource load that shows service end in the current period is higher, to such an extent as to be difficult to, meet the requirement of S the Web Service interface interchange operation of execution that the client per second is complete, in the case, each invokes thread that the execution duration T that client initiatively will be called Web Service interface is greater than 1/S second extends dormancy X second, X (0, T/N] between random value, when the invokes thread operation of client is saturated, means that its all invokes thread all can extend dormancy, and then make it totally call the frequency reduction.Extend the X second of dormancy, X is (0, T/N] between the probability of random value can adopt random probability distribution arbitrarily, but for better embodiment now extends sleep time and the relevance of calling the execution duration T of Web Service interface, in the inventive method X (0, T/N] between the probability of random value be preferably normal distribution probability.Herein, the dormancy time X of prolongation be (0, T/N] between random value, can also play the effect of upsetting client call thread dispatching order, make the invokes thread resource of client self distribute more balanced.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not breaking away from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
