Embodiment
Below in conjunction with accompanying drawing, preferred embodiment is elaborated.Should be emphasized that following explanation only is exemplary, rather than in order to limit the scope of the invention and to use.
Fig. 1 is based on the information resources access structure figure of Web Service.Among Fig. 1, the information resource access method based on Web Service provided by the invention uses Web Service technology, realizes the visit to the information resources of distribution isomery.Wherein relate to information resources integration proxy, Web Service service broker, registration center and information resources access agent.
The information resources integration proxy is to point to the service broker that the information resources access agent returns the user inquiring result.Mainly comprise processes such as query parse and Query Result return.
Web Service service broker is meant the Client-initiated query requests is carried out service discovery, selection and binding.Mainly comprise processes such as service discovery, services selection and service binding.
Registration center is meant and is used for the registration of stored information resource and the service centre that releases news.
The information resources access agent is meant to the user provides query interface, and the Query Result that returns is formatd the service broker of processing.Mainly comprise processes such as user inquiring and Query Result format processing.
Fig. 2 is based on the information resource access method flow chart of Web Service.Among Fig. 2, specifically comprise based on the information resource access method of WebService:
Step 1: the user sends Query Information to the information resources access agent.
Step 2: the information resources access agent carries out match query by Web Service service broker with the information resources of Query Information and registration center's registration, selects Web Service service entry.
The information resources of registration center's registration specifically are Web Service descriptive language wsdl documents, and its concrete registration process is:
At first, the data source and the metadata of information resources integration proxy descriptor resource;
Secondly, data source and the metadata of describing is submitted to Web Service service broker;
Then, Web Service service broker utilizes UDDI (Universal Description Discovery and Integration, universal description discovery and integrated) agreement is encapsulated as WSDL (Web Service Describe Language, Web Service descriptive language) file with data source and the metadata of describing;
At last, utilize the wsdl document of UDDI (Universal Description Discovery and Integration, universal description is found and be integrated) after agreement will encapsulate to register and be published to registration center.
Wherein, data source comprises data source numbering, data source server IP address and database-name.The data source numbering is meant that the information resources integration proxy is the numbering that data source is distributed, and is used for distinguishing different data sources.Metadata comprises numbering, title, description, keyword, founder, creation-time, publisher, update time and the language of metadata.
Step 3: in Web Service service broker, judge whether the user has the access rights of the Web Service service entry of selecting, if the user has the access rights of the Web Service service entry of selecting, then execution in step 4; Otherwise, forward step 10 to.
Step 4: have the Web Service service entry of access rights from the user, determine qualified Web Service service entry.
Determine qualified Web Service service entry, need estimate the performance of Web Service service entry, and the method for service evaluation has multiple different algorithm according to the practical application difference.Can select a kind of algorithm according to actual needs, determine qualified Web Service service entry.
Step 5: (Simple Object Access Protocol: Simple Object Access Protocol) agreement generates the service binding file, and qualified Web Service service entry and service binding file are transferred to the preservation of information resources integration proxy to utilize SOAP.
Step 6:Web Service service broker binds information resources access agent and information resources integration proxy according to the service binding file, realizes the direct communication of information resources access agent and information resources integration proxy.
Step 7: the information resources integration proxy is resolved qualified Web Service service entry.
Step 8: the qualified Web Service service entry behind the information resources integration proxy query parse, obtain information resources, described information resources and service binding file are returned to the information resources access agent.
Step 9: the information resources access agent formats the information resources that receive and handles and return to the user.
Step 10: finish.
Fig. 3 is patterned information resources browsing process figure based on Web Service.Among Fig. 3, be example still, the embodiment based on the information resource access method of Web Service is set forth with " intelligent grid " database.
Step 101: user inquiring.
The user imports " electric power system ", " intelligent grid " key word of the inquiry.
Step 102: service discovery.
Web Service service broker inquires about the key word of the inquiry information that the user sends in the wsdl document of registration center, select satisfactory service.The example partial content of inquiring about from wsdl document is as follows:
Step 103: services selection.
Judge access privilege, if the user has this access rights, then continue visit, otherwise stop visit.
According to related algorithm, filter out more qualified Web Service service entry.The Web Service service entry example partial content that meets user's condition is as follows:
Step 104: service binding.
Use soap protocol, information resources access agent and information resources integration proxy are bound, realize the direct communication of information resources access agent and information resources integration proxy.Service binding file example partial content is as follows:
Step 105: query parse.
Information resources integration proxy end carries out data parsing to selected Web Service service entry.
Step 106: Query Result returns.
The information resources and the service binding file that obtain behind the information resources integration proxy end query parse are directly returned to the information resources access agent.
Step 107: the Query Result format is handled.
Information resources access agent end is presented to the user with the information resources that inquire with specific form.The exemplary query result partial content shows below with html format:
