Embodiment
Below in conjunction with Figure of description, the method for a kind of Web service simulation that the embodiment of the present invention is provided and the embodiment of system and service agency plant thereof and the beneficial effect that can reach thereof are explained in detail.
The framework of a kind of Web service analogue system that the embodiment of the present invention provides when concrete application as shown in Figure 1, comprising:
Service broker's system 11, between service calling system 13 and service provider system 12, it can be both software module, can be also the hardware device that can realize agent functionality;
Fig. 2 is the flow chart of the method for a kind of Web service simulation that provides of the embodiment of the present invention, and the method comprises following step:
S201, service broker's system interception service are called the call request message that terminal is sent, and this service call terminal is the some terminals in service calling system;
Realize the address that this step is revised as the address in the service provider system of the method for request call in this call request message is provided of the target ip address in call request message in service broker's system by service call terminal;
S202, service broker's For Solutions of Systems are separated out this call request message and are comprised Service name, method name, input parameter type;
The method name of each method that S203, service broker's system comprise according to the Service name of each default service, service is, the corresponding relation of the input parameter type of each method and each method analog form is searched analog form corresponding to method that described call request message request is called, if lookup result is whole analog forms, carry out S204, if lookup result is partial simulation mode, carry out S206;
S204, service broker's system generate response message according to the first default simulated templates;
S205, service broker's system are back to service call terminal by the response message generating in S204;
Like this, service call terminal no longer relies on service provider system, can reduce the pressure of service provider system, avoids the unstable of service call that the fault due to service provider system causes;
S206, this call request message of service broker's system forwards are to service provider system;
After S206, carry out S207;
S207, service broker's system receive the response message that service provider system returns;
S208, service broker's system process according to the second default simulated templates the response message receiving in S207;
S209, service broker's system are back to service call terminal by the response message after processing in S208.
Further, the Service name, the method name of each method that comprises of service, the corresponding relation of the input parameter type of each method and each method analog form that in S203, set in advance each service are specifically realized by following manner:
The address of respectively serving corresponding WSDL WSDL that service broker's system access sets in advance, obtains and respectively serves corresponding WSDL description; Or service broker's system receives the WSDL description that the WSDL description document of serving obtains this service; Each serves service broker's system analysis corresponding WSDL and describes, and obtains institute methodical method name, the input parameter type of each method and the parameter name of output parameter, the parameter type comprising in the Service name, this service of this service and stores; Service broker's system is by Service name, the method name of each method comprising, each method analog form corresponding stored of the input parameter type of each method and setting of each service obtaining.
Fig. 3 provided set in advance each service Service name, the method name of each method that comprises of service, the realization flow of the corresponding relation of the input parameter type of each method and each method analog form:
S301, WSDL getter in service broker's system receives WSDL address or the WSDL description document of certain service from operator, if the reception of WSDL getter is WSDL address, carry out S302, if what WSDL getter received is WSDL description document, carry out S304;
S302, the WSDL address that the access of WSDL getter receives, this WSDL address for example can be arranged in service provider system; Then carry out S303;
S303, service provider system returns to the WSDL description document of its request access to WSDL getter;
S304, WSDL getter is sent to the WSDL resolver in service broker's system by the WSDL description document getting;
S305, the WSDL description document receiving in WSDL resolver resolves S304; As all methods, the method name of each method, parameter name, the parameter type of the input parameter type of each method and output parameter that comprise in service;
S306, WSDL resolver is sent to database access object request storage by the result parsing.
S307, the result that database access object goes out WSDL resolver resolves is put into database and is stored;
S308, database returns and adds successful message to operator;
S309, database receives the analog form that operator arranges each method comprising in this service of adding;
S310, the corresponding stored of the analog form of the method name of each method that database comprises the Service name of this service, this service, the input parameter type of each method and each method.
Then, the corresponding relation of the analog form of the method name of each method comprising in this service, the input parameter type of each method and each method is all deposited into after database, the analog form of all methods that comprise in the new service that operator continues to add new service and interpolation is set.
Further, the first simulated templates in step S204 generates in advance by following step:
First, the method name of each method that service broker's system comprises according to the Service name of each service, service is, the corresponding relation of the analog form of the input parameter type of each method and each method finds out the method that is set to whole analog forms;
Then, for each method that is set to whole analog forms, the parameter type of each output parameter of the method being obtained according to parsing by operator arranges corresponding parameter value for it, and then operator is kept at the parameter name of the parameter value of the output parameter of setting and corresponding output parameter, parameter type in database as the first simulated templates.
Below the form of the first simulated templates is illustrated, Fig. 4 has provided a kind of form (the embodiment of the present application is not limited to this kind of form certainly) of serving the first simulated templates of a certain method in the service that is called S, the method F by name of the method, method F comprises two output parameters, its parameter name is respectively parameter S F1 and parameter S F2, the parameter type of parameter S F1 is int, the parameter type of parameter S F2 is float, operator is made as integer A according to the parameter type int of parameter S F1 by its parameter value, according to the parameter type float of parameter S F2, its value is made as to single precision floating datum B.
Further, in step S204, the detailed process that service broker's system generates response message according to the first default simulated templates is:
First service broker's system judges the agreement that call request message is used, the response message of the protocol generation corresponding format of then using according to this call request message, last inserts the content of the first simulated templates corresponding to the method for calling with this call request message request of storage in above-mentioned response message again.
It is example that the service call terminal of take is below used soap protocol to send call request message, illustrates that service broker's system generates the process of response message according to above-mentioned the first simulated templates:
First, to judge the agreement that call request message that service call terminal sends uses be soap protocol to service broker's system; Concrete deterministic process for example can adopt following manner: can be for the different agreements pre-configured different entrances of acting on behalf of of service broker's system, suppose that service broker's system opened two ports 8080,8081, wherein 8080 port bindings soap protocol, 8081 port bindings Transmission Control Protocol, if therefore 8080 ports of service broker's system receive call request message, think that this call request message is used soap protocol.
Then, service broker's system generates the response message of soap protocol form, it comprises a SOAP big envelope, in SOAP big envelope, comprise SOAP header (can have also and can not have) and SOAP message content (must have), wherein SOAP message content is the content being kept in the first simulated templates, and the content of this first simulated templates as shown in Figure 4, so the response message that service broker's system returns to service call terminal as shown in Figure 5.
The method of above-mentioned whole analog forms call the situation that can be applied to not need to be concerned about service provider system interior details, now when service provider system is delayed machine due to hardware fault or other reasons, service broker's system is respond services calling system directly, thereby isolated the impact of service provider system on service calling system, make large at service provider system pressure or delay machine in the situation that, research and development test can continue or provide online service can not be out of order.
In addition, the situation of this whole analog forms can also be applied to research and develop in test environment, thereby by service broker's system, is now that service calling system returns to response message some leaks in examination service calling system easily.With two concrete examples, illustrate below:
In a certain test scene, A system need to be called certain service in B system, and when now A system need to arrange a time-out time t B system is not returned to response message yet so that A system was waited for over the t time after sending call request message, A system can active break request.Otherwise, if A system is waited for the response message of B system always, can affect the processing of A system to other services, if the words that even a plurality of services of A system call all do not meet with a response, in A system, the service of wait-for-response can get more and more so, finally may cause the system failure.
And in test process, need to verify that whether this timeout treatment mechanism is reliable, and therefore service broker's system can be set between A system and B system, A system is by the service of this service broker's system call B system.In the situation that all simulating, the operator of service broker's system can arrange a response wait time t1 in service broker's system, t1>t wherein, be that service broker's system waits for that after receiving call request message t1 returns to response message to A system after the time again, if A system is no longer processed the response message returning, illustrate that A system is provided with timeout treatment mechanism; If A system continues the response message returning to process, illustrate that A system does not arrange timeout treatment mechanism.Like this, can in test, whether be provided with timeout treatment mechanism by service for checking credentials calling system, or whether the timeout treatment mechanism arranging is reliable.
In another test scene, in SOA, service may be distributed in each system, as A system and B system have respectively the ability that certain service is provided, service in service calling system (A system) request call service provider system (B system), after getting the result that service provider system (B system) returns, can proceed the processing of own service, at this moment just need to consider that the idempotence of the result that service calling system (A system) returns service provider system (B system) is controlled.As having, A system collects the function of certain expense for transfer accounts successful backward client of client, and B system has the service of transferring accounts, A system need to be called the service of transferring accounts of B system, A system is directly deducted fees to client after receiving the successful result of transferring accounts of B system, what need to consider in when test is the same operation of transferring accounts for client, can only deduct fees once after transferring accounts successfully.And in service invocation procedure, B system may repeatedly turn back to A system by the successful result of transferring accounts, and just needs A system to have idempotence to control here, for the same operation of transferring accounts, no matter A system is received the successful result of transferring accounts that B system is returned several times, A system is all only deducted fees once.When whether checking A system has idempotence control, just can be by service broker's system being set between A system and B system, A system is by the service of transferring accounts of service broker's system call B system, B system returns to A system the successful result of transferring accounts by service broker's system, the number of times that returns to the successful result of transferring accounts to A system can be set easily in service broker's system, to simulate B system, the successful result of transferring accounts repeatedly be turned back to the scene of A system.Then according to A system, the same number of times of deducting fees of transferring accounts operation is judged to whether A system has idempotence and control.
Further, in step S206, this call request message of service broker's system forwards to the detailed process of service provider system as shown in Figure 6:
The address that is forwarded to service provider system of the method for S601, service broker's system searching request call;
Its detailed process is, service broker's system, according to the source IP of call request message, Service name, method name and input parameter type, is searched the address that call request message need to be forwarded to service provider system in the corresponding relation of the source IP of pre-stored Service name, method name, input parameter type, call request message and the address of service provider system;
In research and development test, in service provider system and service calling system, may there be a plurality of research and development tasks to carry out simultaneously, for example ought there be two research and development tasks, task 1 and task 2, while carrying out simultaneously, a part of terminal in service provider system provides service call for task 1, another part terminal provides service call for task 2, a part of terminal in service calling system is carried out the research and development of task 1, another part terminal is carried out the research and development of task 2, research and development tester wishes when processing service call, the call request message being sent by research and development task 1 is only processed by the system of research and development task 1, the call request message being sent by research and development task 1 is only processed by the system of research and development task 1, therefore when searching call request message repeating to the address of service provider system, just need to know the source IP of call request message, and owing to may comprising two methods that method name is identical in same service, these two unique differences of method are that their input parameter type is different, so service provider system must could judge which method is service call terminal will call actually according to Service name, method name, three kinds of information of input parameter type.Therefore, the address that is forwarded to service provider system of the method that search request is called in this step can not only be searched according to method name, and will be first according to the source IP of call request message, judge that this call request message will those terminals in service provider system process, again according to Service name, first method name and input parameter type judge which method service calling system will call actually, and then in service provider system, process the address of searching the method for processing this request call in those terminals of this call request message.
If find, perform step S602, if search less than, perform step S603;
In step S602, service broker's system forwards call request message is to the address of the service provider system finding;
In step S603, service broker's system judges whether to have set in advance acquiescence forwarding address, if so, performs step S604, if not, performs step S605;
In step S604, service broker's system forwards call request message is to giving tacit consent to forwarding address;
In step S605, service broker's system is returned to fault alarm information to service call terminal.
Further, the second simulated templates in step S208 generates through the following steps:
First, the method name of each method that service broker's system comprises according to the Service name of each service, service is, the corresponding relation of the analog form of the input parameter type of each method and each method finds out the method that is set to partial simulation mode;
Then, for each method that is set to partial simulation mode, first operator determines that those output parameters in whole output parameters of the method need simulation, and then for needing the output parameter of simulation, according to its parameter type, corresponding parameter value is set, finally the corresponding parameter value of parameter name, parameter type and the setting of the output parameter of needs simulation is saved as to the second simulated templates.
Fig. 7 has provided the form (the embodiment of the present application is not limited to this kind of form certainly) of the second simulated templates of a certain method in the service of serving S by name, the method M by name of the method, comprise three output parameters, its parameter name is respectively parameter S M1, parameter S M2 and parameter S M3, the parameter type of parameter S M1 is int, the parameter type of parameter S M2 is float, the parameter type of parameter S M3 is double, first, operator determines in all output parameters of the method M only needs to simulate SM3, therefore operator is made as double-precision floating points D according to the parameter type double of parameter S M3 by its parameter value, therefore the second simulated templates of the method M has only been preserved service S, the parameter name of method M and output parameter SM3, the content of parameter type and parameter value.
Further, in step S208, the detailed process that service broker's system processes according to the second default simulated templates the response message receiving in step S207 is:
The modify parameteri of the output parameter that the parameter name of the output parameter comprising with the second simulated templates that service broker's system comprises this response message is consistent for the second simulated templates in parameter value corresponding to the parameter name of this output parameter.
Still with service call terminal, use soap protocol to send call request message below, the method for request call, for the method M in service S is example, illustrates the process of the response message that service broker's system receives in S207 according to the second simulated templates processing:
The response message that the service provider system that service broker's system receives in S207 returns as shown in Figure 8, wherein the content of SOAP message comprises parameter name, parameter type and the corresponding parameter value of service S, method M and three output parameters, the parameter type of parameter S M1 is int, its parameter value is integer J, the parameter type of parameter S M2 is float, its parameter value is single precision floating datum K, and the parameter type of parameter S M3 is double, and its parameter value is double-precision floating points L.
Then, it is the parameter value double-precision floating points D that parameter S M3 arranges that service broker's system 11 replaces with operator by the parameter value of the parameter S M3 in the response message receiving in S207 by double-precision floating points L according to the second simulated templates shown in Fig. 7, the SOAP message after processing according to the second simulated templates shown in Fig. 7 as shown in Figure 9, before processing, be that the parameter value of parameter S M3 is different with the difference of SOAP message after processing, before processing, the parameter value of parameter S M3 is L, and after processing, the parameter value of parameter S M3 is D.
In when application for complicated service; the output parameter of a method conventionally can be many; operator will completely arrange the whole output parameter workloads of simulation can be larger; therefore the response message returning by service provider system here; operator only need arrange the output parameter that oneself needs simulation; the integrality that can guarantee so on the one hand the output parameter that returns, has also overcome the more loaded down with trivial details problem of all output parameters of simulating on the other hand.
With a concrete example, illustrate below: A system can provide a kind of service AS, the output parameter of this service has ASF1, ASF2, wherein ASF1 processes the True Data that this service obtains, and the result phase of ASF2 for this service is processed, may have several return values of ASF21, ASF22; And when B system need to be called the service AS of A system, B system need to be processed calling the various result phases that AS may occur, and B system is not understand the specific implementation details of the service AS of A system in actual applications, if desired the various result phases of simulating AS service when there is no service broker's system certainly will need to drop into understands realizing details and can accurately simulating out of AS service, and if the modes that adopt all simulations are because the output parameter ASF1 content of method AS may be very complicated, all simulate, setting up can be very loaded down with trivial details.Therefore adopt partial simulation, the output parameter that needs simulation is only set, the content of all the other output parameters is still generated when responding the method by A system, thereby simplifies template-setup, raises the efficiency.
For example, the service AS that A system provides is the service of checking user account remaining sum, during the service AS of B system call A system, A system is returned to the remaining sum (corresponding output parameter ASF1) of checked user account to B system, and to B system, return to the state (corresponding output parameter ASF2) of this user account, as when this user account, Sorry, your ticket has not enough value 10 yuan time, to B system, return to the information that Sorry, your ticket has not enough value (corresponding A SF21), and when the remaining sum of this user account surpasses a certain regulation amount, to B system, return to the information (corresponding A SF22) that remaining sum transfinites, because B system need to be processed calling the various result phases that AS may occur, therefore between A system and B system, service broker's system is set, A system returns to B system by the output parameter ASF1 of the service AS of B system call and ASF2 by agency plant, adopt the mode of partial simulation, service broker's system can be revised the value of ASF2 so that the various result phases of analog service AS, whether check B system can make correct processing to different result phases, while receiving as B system the information that Sorry, your ticket has not enough value, whether can point out user to supplement with money, or when receiving the information that remaining sum transfinites, whether can point out user to process account so that remaining sum no longer transfinites.And to serving the output parameter ASF1 of AS, the value that agency plant can directly adopt A system to generate when processing this service, needn't be at the parameter value of simulation ASF1.
In software test procedure, adopting the advantage of service broker's system is to simulate easily the various state values of serving AS Output rusults in A system, with check B system, to all result phases of returning of service AS, can correctly process, the probability occurring to reduce leak, this leak refers to that the result phase that B system is returned service AS can not correctly process.Service broker's system can be more convenient the various result phases of returning that obtain serving AS, thereby improve efficiency of research and development, conventionally test mode also can be done test simulation so far as Debug, but its simulated cost can be very high.
Preferably, the method of a kind of Web service simulation that the embodiment of the present invention provides also comprises that the method for request call in call request message is set to the situation of non-analog form, in this case, service broker's system directly forwards call request message to service provider system, detailed process and the process shown in Fig. 6 of its forwarding are similar, do not repeat them here; Service provider system, after receiving the call request message of forwarding, carries out normal process, then to service broker's system, returns to response message, and service broker's system is not made any extra process to this response message and is directly forwarded to service call terminal.
The Web service of take below based on SOAP is example, illustrates that the method for a kind of Web service simulation that the embodiment of the present invention provides is served the process of simulation when concrete application, and as shown in figure 10, this process comprises the following steps:
Certain service call terminal in S1001, service calling system is sent the call request message based on soap protocol,
Because service calling system is revised as the address in service broker's system by the address in the service provider system of needs access, therefore service calling system sends after call request message, is actually SOAP call request message and directly sends to the receiver address in service broker's system;
Message blocker interception SOAP call request message in S1002, service broker's system;
S1003, message blocker send SOAP call request message to the packet parsing device 102 in service broker's system;
S1004, packet parsing device take out source IP and the soap message wherein of call request message and resolve this soap message, obtain Service name, method name and input parameter type, and the method name of each method comprising according to the Service name of pre-stored each service in database (not shown in Figure 10), service is, the corresponding relation of the analog form of the input parameter type of each method and each method finds out the analog form of the method for request call;
The analog form of the method for Service name, method name, the input parameter type of the request call that S1005, packet parsing device send SOAP call request message, source IP, parse and the request call finding is to the message repeating device in service broker's system;
If the method for request call is set to whole analog forms and carries out S1006; If the method for request call is set to partial simulation or non-analog form is carried out S1007;
S1006, message repeating device forward SOAP call request message to the message constructor in service broker's system;
S1007, message repeating device find out the address that is forwarded to service provider system of the method for the request call that is set to partial simulation mode or non-analog form according to the source IP of pre-stored Service name in database, method name, input parameter type, call request message and the corresponding relation that is forwarded to the address of service provider system;
S1008, message repeating device forward SOAP call request message to the address finding in S1007; If do not find the address that is forwarded to service provider system in S1007, and the also default address of Non-precondition, to service calling system, return to fault alarm information, this situation is not shown in Figure 10;
