Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
In the prior art, the definition mode to the relevant schema information of business in WSRP and BPEL is different.Wherein, in WSRP, just utilize wsdl (Web Services Description Language, the web service description language (sdl)) defines general schema information, can not embody the characteristic of specific transactions, thereby in specific service logic, can't directly use this information; In BPEL, the schema information of definition can directly embody the characteristic of specific transactions.Because the definition mode to the relevant schema of business in WSRP and BPEL is different, can't realize the seamless integrated of WSRP and BPEL, this just makes can't realize reusing of user interface and service logic.
Therefore, for realizing reusing of user interface and service logic, the embodiment of the invention one provides a kind of method that realizes combinations of services.As shown in Figure 1, the method for the embodiment of the invention one comprises:
In this step, client is by URL (Uniform Resource Locator, URL(uniform resource locator)) visit composite service, and this URL is the address of the composite service that generates in professional loading procedure.In described business request information, can also include conversation message, service request parameter etc.
Need to prove, the embodiment of the invention mainly is HTTP (the Hyper Text Transfer Protocol that handles from client, HTML (Hypertext Markup Language)) format messages, but not the message of SOAP (Simple Object Access Protocol, Simple Object Access Protocol) form.The process of the message of treatment S OAP form is with of the prior art identical.
Lack professional specific description because the wsdl of present WSRP describes, be not enough to support the combination of user interface and service logic, therefore, to the business description information expansion of WSRP, increase the interface and generate parametric description in embodiments of the present invention.Described interface generates the parameter that parameter is meant need be provided when generating the interface; This parameter can be presented to client with the interface combinations that WSRP provides together.
In addition, portability interface required parameter in business request information, described interface required parameter is meant the parameter that client can be imported in the interface; This parameter sends to combine engine by client.
In this embodiment, for convenience of description, also proposed the notion of interface call parameters, it can comprise: the daughter element of movable input variable is called at the interface, the input variable that perhaps comprises the interface activity of calling comprises that perhaps the interface of the interface activity of calling generates parametric variable.Under different situations, this step can realize by following several modes.
Wherein the process of mode one is:
Step 121, the input variable assignment of WSRP given call movable input variable, and described interface is generated parameter convert the WSRP form to, and the interface after the format conversion is generated the parameter assignment is called the input variable (input) of activity (invoke activity) to the interface daughter element.Corresponding schema can be expressed as following form:
<complexType?name＝″NamedString″>
<sequence>
<element?name＝″value″type＝″xsd:string″minOccurs＝″0″/>
</sequence>
<attribute?name＝″name″type＝″xsd:string″use＝″required″/>
</complexType>
In the process of assignment, the interface after the format conversion can be generated the daughter element that the parameter assignment is given the input variable of invoke activity, for example formParameters element.If this WSRP corresponding page is the homepage of composite service or when not needing to receive the user and importing, then this invoke unbounded is looked unfamiliar into parametric variable, does not then need assignment.
At this, Schema (pattern) is simply introduced.Schema mainly is a kind of language that is used to describe with the logical construction of standard XML document, and the effect of its maximum is exactly the correctness of verifying XML file logical structure.
Step 122, generate the interface message call, in the message call of described interface, comprise the address information of specifying WSRP interface business, and described message is sent to the WSRP server according to described input variable.
At this, mainly be the soap message that calls according to the input message variable generation interface of assembling.
Step 123, reception are called response message by the interface that the WSRP server sends, call at described interface and to comprise corresponding interface information in the response message, wherein said interface information is that the interface of described WSRP server after according to initial page that is provided and described format conversion generates parameter and assemble.
The process of mode two is:
Step 1211, described interface is generated parameter convert the WSRP form to, and the interface after the format conversion is generated the parameter assignment call movable input variable to the interface.
Step 1221, when determining that described interface calls movablely during for the calling of WSRP type, generate interface message call framework according to the input message element of described WSRP.
Step 1231, the xml fragment that insertion generates according to the described input variable of calling movable correspondence in the message call framework of described interface, generation interface message call.
Step 1241, reception are called response message by the interface that the WSRP server sends, call at described interface and to comprise corresponding interface information in the response message, wherein said interface information is that the interface of described WSRP server after according to initial page that is provided and described format conversion generates parameter and assemble.
The process of mode three is:
Step 1212, the input message element that the interface service is corresponding call movable input variable as the interface, and described interface is generated parameter convert the WSRP form to, and the interface after the format conversion is generated the parameter assignment call movable interface to the interface and generate parametric variable.
Step 1222, generate parameter and generate the interface message call, in the message call of described interface, comprise the address information of specifying WSRP interface business, and described message is sent to the WSRP server according to described movable input variable and the interface of calling
Step 1232, reception are called response message by the interface that the WSRP server sends, call at described interface and to comprise corresponding interface information in the response message, wherein said interface information is that the interface of described WSRP server after according to initial page that is provided and described format conversion generates parameter and assemble.
Step 131, carry out answer activity (reply activity), and call response message according to described interface and generate service response message.
At this, can at first extract the movable pairing interface information of reply, also promptly extract described interface and call information such as mimeType, markupString in the response message, wherein mimeType is as the HTTP head of described service response message, and markupString is as the HTTP body of described service response message.
Step 132, described client end interface is sent to client by described service response message.
In addition, before described step 132, also can be included in the step of inserting the pairing session information of described composite service in the described service response message, make the later service request of client can both carry this conversation message; And the successor operation address in the described service response message replaced with the step of the address of combine engine, thereby make the subsequent requests of client all handle by described combine engine.
By above description as can be seen, the method of the realization combinations of services of the embodiment of the invention one, making by the interface generation parameter of expanding can be seamless integrated between WSRP and BPEL, thereby BPEL simultaneously combined user interface and service logic, thereby realize reusing of user interface and service logic.
On the basis of embodiment one, the method for the embodiment of the invention two realization combinations of services can comprise as shown in Figure 2:
The WSRP business wherein the universal description that defines, can comprise that also the interface at this specific transactions interface generates parameter, interface required parameter to operation list issuing service descriptor in the WSRP standard.In WSDL describes, in the operation of correspondence describes, except that input message, output message element, also increase UIGenerate message, UIRequest message element.These two element particular contents and WSRP business are closely related, and different WS RP business has different the description.When creating the composite service of zone boundary face, introduce professional WSDL from operation list, comprising the WSDL of web service and WSRP.
According to different situations, in program, can introduce different processing modules.
For example, when need receiving from the message of client and this message, generate receive activity (receive activity) from the WSRP interface, and with the interface required parameter of this WSRP correspondence as the movable corresponding variable of this receive.
For example, in the time of need obtaining the WSRP interface to the user, generate the invoke activity, and the interface of this WSRP correspondence is generated parameter generate variable as the movable corresponding interface of this invoke, with the input message variable of WSRP correspondence as the movable corresponding input variable of this invoke; Perhaps with the input message variable of WSRP correspondence as the movable corresponding input variable of this invoke, the interface of WSRP correspondence is generated the daughter element of parameter as the movable corresponding input variable of this invoke; Perhaps the interface with the WSRP correspondence generates parameter as the movable corresponding input variable of this invoke.
For example, when needing program WSRP interface to give the user, generate the reply activity, and the soap message that returns will call WSRP the time is as the movable corresponding variable of this reply.
At last, the business that loads establishment is to combine engine, and the address of generation composite service, calls for service requester.The address of wherein said composite service both can generate in creation environment, also can generate in combine engine.
In this step, can comprise following process:
Step 221, determine whether that according to described business request information needs create the composite service example again.
Concrete determination methods is: when determine in described business request information, to include described session information, when in combine engine, having found corresponding composite service example, determining does not need to create again the composite service example, obtains the interface required parameter in the described business request information simultaneously.Execution in step 222 then.
And when determining in described business request information, not comprise described session information or determining in described business request information, to include session information but when in combine engine, not finding corresponding composite service example, determine to create the composite service example again.Again create composite service this moment, flow process finishes.
Step 222, judge whether described interface required parameter is XML (Extensible Markup Language, extend markup language) form.When described interface required parameter is the XML form, utilize the schema of the interface required parameter correspondence of movable pairing WSRP described in the described composite service example to verify whether described interface required parameter is legal.If described interface required parameter is not the XML form, also need described interface required parameter is converted to the XML form, and then utilize the schema of the interface required parameter correspondence of movable pairing WSRP described in the described composite service example to verify whether described interface required parameter is legal.
At the form of checking described interface required parameter when whether being legal, at first to obtain the schema information of the WSRP interface required parameter of the movable correspondence of this receive by the composite service of creating, utilize this described interface of schema Information Authentication required parameter whether legal then.
When if described interface required parameter is illegal, flow process finishes.When described interface required parameter is legal, execution in step 223.
The process of step 23-24 is referring to the process prescription of above-mentioned steps 12-13.
The method of the realization combinations of services by the embodiment of the invention two, interface by expansion generates parameter, the interface required parameter makes can be seamless integrated between WSRP and BPEL, thereby BPEL simultaneously combined user interface and service logic, thereby realize reusing of user interface and service logic.
Describe the method for the realization combinations of services of the embodiment of the invention in detail below in conjunction with embodiment three.
In this embodiment three, suppose to have the composite service of a virtual tourism business, this embodiment only analyzes its login part.Mainly comprise two WSRP interfaces in this login part, one is login interface (homepage), and another is the interface of login successfully afterwards.In addition, also comprise a Web Serivce (Web service), be used to provide user profile (user profile), user profile is carried out authentication, and user's current urban information is provided.
Wherein, do not need the interface to generate parameter in the WSRP login interface, but need the interface required parameter.Its median surface required parameter has encapsulated user's login user, login password information.In the operation of this WSRP, increase UIRequest message.For example,
<wsdl:operation?name＝″getMarkup″>
<wsdl:input?message＝″intf:getMarkup″name＝″getMarkup″/>
<wsdl:output message＝″intf:getMarkupResponse″
name＝″getMarkupResponse″/>
<ext:UIRequest?message＝″intf:loginInfo″name＝″loginInfo″/>
</wsdl:operation>
WSRP logins and puts aside the interface required parameter in the successful interface, and its median surface generates the current urban information that parameter has mainly encapsulated the user.In the operation of this WSRP, increase UIGenerate message.
For example:
<wsdl:operation?name＝″performBlockingInteraction″>
<wsdl:input message＝″intf:performBlockingInteraction″
name＝″performBlockingInteraction″/>
<wsdl:output message＝″intf:performBlockingInteractionResponse″
name＝″performBlocking?InteractionResponse″/>
<ext:UIRequest message＝″intf:other″name＝″other″/>
<ext:UIGenerate message＝″intf:cityInfo″name＝″cityInfo″/>
</wsdl:operation>
For this composite service, the combinational logic main contents are as follows:
<bpws:receive?createInstance＝″yes″name＝″initiate″operation＝″initiate″partnerLink＝″eTourPL″portType＝″ns1:eTourPT″variable＝″initiateIn″/>
Wherein, this receive activity mainly is based on the HTTP request that the user receives, creates a composite service example.
<bpws:invoke?inputVariable＝″WSRPHomepageInput″name＝″INV-HomepageWSRP″operation＝″getMarkup″UIGenerate＝″″outputVariable＝″WSRPHomepageOutput″partnerLink＝″WSRPHomepagePL″portType＝″ns2:WSRPHomepagePT″/>
Wherein, this invoke activity mainly is to call homepage WSRP, obtains the homepage of this composite service, and wherein the UIGenerate parameter is empty.
<bpws:reply?name＝″RPL-initiate″operation＝″initiate″partnerLink＝″eTourPL″portType＝″ns1:eTourPT″variable＝″WSRPHomepageOutput″>
Wherein, this reply activity mainly is that the WSRPHomepageOutput variable is changed into HTTP message, and sends to client.
<bpws:receive?name＝″RCV-Login″operation＝″Login″partnerLink＝″eTourPL″portType＝″ns1:eTourPT″variable＝″UIRequestVarLoginInfo″/>
Wherein, this receive activity mainly is the logging request that receives from client, and wherein UIRequestVarLoginInfo is the interface required parameter that homepage WSRP provides.
<bpws:invoke?inputVariable＝″UIRequestVarLoginInfo″name＝″INV-authenticate″operation＝″authenticate″outputVariable＝″citiInfo″partnerLink＝″authenticatePL″portType＝″ns4:authenticatePT″/>
Wherein, this invoke activity is mainly called the authentication business user is authenticated, and returns the user and give tacit consent to urban information.
<bpws:invoke?inputVariable＝″WSRPLoginSuccessInput″UIGenerate＝″citiInfo″name＝″INV-LoginSuccessWSRP″operation＝″performBlockingInteraction″outputVariable＝″WSRPLoginSuccessOutput″partnerLink＝″WSRPLoginSuccessPL″portType＝″ns3:WSRPLoginSuccessPT″/>
Wherein, this invoke activity mainly will be logined the interface generation parameter input message parameter combinations formation WSRP recalls information corresponding with WSRP of successful interface WSRP.
<bpws:reply?name＝″RPL-Login″operation＝″Login″partnerLink＝″eTourPL″portType＝″ns1:eTourPT″variable＝″WSRPLoginSuccessOutput″>
Wherein, this reply activity mainly is that the WSRPLoginSuccessOutput variable is changed into HTTP message, and sends to client.
As shown in Figure 3, the method for the realization combinations of services of the embodiment of the invention three can comprise following process:
Step 31, client are by HTTP message http://ip:port/eTour visit homepage.
Step 33, combine engine are carried out the invoke activity of homepage WSRP, call homepage (being login interface) WSRP.Because it is empty that the interface generates parameter UIGenerate, therefore direct input message element according to the WSRP correspondence generates the SOAP request.
Step 34, homepage WSRP extract corresponding interface after receiving described SOAP request.Because the interface required parameter is empty, so do not need the interface reorganization.
Step 35, described homepage WSRP are included in interface information in the soap message and return.
Step 36, combine engine are carried out the reply activity, extract mimeType in the described soap message as the http head, extract markupString as the http body, generate HTTP message.
Owing to carry follow-up register in the interface,, make follow-up login through combine engine with the address that the address is made as combine engine of submitting of register.Simultaneously in HTTP message, insert session information, form http response message.
Step 37, combine engine return to client by described http response message with login interface.
Step 38, client are inputed user name, password and are submitted.
Step 39, client are asked to combine engine according to the address transmission HTTP that submits after replacing.Does this HTTP ask similar http://ip:port/eTour/login? user=admin﹠amp; Password=admin.Wherein in this request, also comprised session information mutual in the step 36.
Step 310, combine engine are carried out the receive activity, extract the session information of HTTP request, find corresponding composite service according to session information.Convert this HTTP request to the xml form simultaneously, as follows.
<login><user>admin</user><password>admin</password></login>
While is verified by the BPEL variable of back assignment to the receive correspondence according to the HTTP request message that the schema of the interface required parameter of the current needs processing of composite service verifies this xml form.
Step 311, combine engine are carried out web service and are called activity (invoke), and user profile is verified.
After step 312, checking are passed through, return user's acquiescence urban information, for example＜city〉shenzhen＜/city 〉.
Step 313, combine engine are carried out WSRP invoke activity, the interface is generated parameter (promptly giving tacit consent to the city variable) convert the WSRP form to, and be as follows:
<formParameters?name＝″city″><value>shenzhen</value></formParameters>。Simultaneously the input element according to activity generates interface message call framework, and the interface behind the format transformation is generated parameter is inserted in the interactionParams element in the message framework, and generates logining the recalls information of successful WSRP.
Step 315, WSRP server return the successful interface of login, and the current city of explicit user.
Step 317, combine engine are returned the successful interface of login and are given client.
The method of the realization combinations of services by the embodiment of the invention three, interface by expansion generates parameter, the interface required parameter makes can be seamless integrated between WSRP and BPEL, thereby BPEL simultaneously combined user interface and service logic, thereby realize reusing of user interface and service logic.
