Description
Technical field
The present invention relates to a kind of method of providing services on the Internet based on middleware platform, especially a kind of based on CAR (Component Assembly Runtime, parts dynamically assemble) middleware platform, the method for providing services on the Internet by operation CAR network service agent program on this CAR middleware platform.
Background technology
Along with development of internet technology, the technology of network service will be with SOA (Service OrientedArchitecture, Enterprise SOA) is framework, SOA is a measured tissue and method for designing, it is a protocol frame, it utilizes a series of network share service, makes IT can more closely serve operation flow.By adopting the standard interface that can hide the potential technology complexity, SOA can improve the rate of reusing of IT assets, thus the business service after having accelerated exploitation and having paid new enhancing more reliably.
In general SOA comprises three basic composition elements: service user, ISP and service register center.
Web services technologies based on the SOA notion is that direct To enterprises application program is integrated, for the operation flow of semi-automatic interactive mode and organization internal provides the public data switching plane.The technology that constitutes the network service comprises XML (Extensible Markup Language, autgmentability identifiable language), HTTP (Hypertext Transfer Protocol, HTML (Hypertext Markup Language)), SOAP (Simple ObjectAccess Protocol, Simple Object Access Protocol) and WSDL (Web Service DescriptionLanguage, webserver descriptive language).XML is used for the structure of message between the define grid service, and HTTP is the medium of communication of bottom, and SOAP is the container that exchanges messages, and WSDL is used to describe the network service.
At present, occurred many network service development instruments on the market, these network service development instruments can be divided into following a few class substantially:
The network service development platform of enterprise-level: typical case's representative of such developing instrument comprises Microsoft.NET, Sun J2EE, IBM WebSphere, BEA WebLogic, Systinet Webservices, Apache XML Project:Axis, Oracle 9i Application Server andJDeveloper, Borland JBuilder etc.Such developing instrument provides from programming language, uses class libraries a whole set of solution to running environment etc.Main advantage is the main flow developing instrument of network service at the network service development of enterprise-level.
The network service development instrument of lightweight: typical case's representative of such developing instrument comprises gSOAP, SOAP::Lite, easySOAP etc.The main advantage of such developing instrument is to be simple and easy to bells and whistleses such as usefulness or open source code, and such instrument often can not provide a whole set of network service to use class libraries and development platform.
Except two above class main flow developing instruments, some manufacturers also provide some network service development bags, and typical case's representative is Microsoft SOAP Toolkit (SOAP of a Microsoft kit).
Above-mentioned network service development instrument exists deficiency as described below: on the one hand, though occurred considerable network service development instrument in the market, but these instruments are often based on a whole set of architecture that rebulids, existing software product in the multiplexing original middleware platform of a kind of simple and effective way (for example CORBA, Microsoft DCOM etc.) is not provided.Often be widely used and actual conditions are these middleware platforms, reached sizable scale based on the product of these middleware platforms.On the other hand, though some software vendors have also issued some network service software kits to simplify the workload that the user utilizes original middleware product to provide services on the Internet, for example, the IDL that provides among the Microsoft SOAPToolkit (Interface Definition Language, IDL) file conversion instrument, but when issuing an original software finished product at every turn and be the network service, the developer still needs to finish suitable repeated workload.
Summary of the invention
The objective of the invention is to deficiency and defective at above-mentioned existing network service development instrument existence, a kind of method of providing services on the Internet based on middleware platform is provided, by the existing software product of this method in can multiplexing original middleware platform, and reduce the workload that repeats.
To achieve these goals, the invention provides a kind of method of providing services on the Internet based on middleware platform, this method may further comprise the steps:
The packet of step 1, remote client's the SOAP requested packets or the download request of wsdl document arrives the webserver, and the webserver starts CAR network service agent program on the CAR middleware platform;
Step 2, described CAR network service agent program are resolved the packet of the download request of described SOAP requested packets or wsdl document;
Step 3, described CAR network service agent program are finished the service of the download request of described SOAP request or wsdl document by described CAR middleware platform.
As shown from the above technical solution, the present invention is the support of adopting the CAR component technology that the SOA technology is provided, for the remote client provides services on the Internet.The CAR component technology is the programming model of component-oriented programming, and it has stipulated the standard called mutually between one group of member, makes that the binary system member can self-described, can dynamic link when operation.
The COM (Component Object Model, The Component Object Model) of the compatible Microsoft of CAR, but compare with the COM of Microsoft, CAR have deleted agreement out-of-date among the COM, forbid the non-self-described interface of user definition COM; The self-described function of complete member and interface thereof has realized the expansion to COM; The user interface of COM has been carried out simplifying packing, be easy to learn and use.
From top definition, we we can say that CAR is the subclass of the COM of Microsoft, while expands the COM of Microsoft again, at " with glad " SDK (Software Development Kit, SDK) under the support of instrument, make advanced component programming technology hard to understand be easy to be understood by the C/C++ programmer and grasp.The programming idea of CAR is the marrow of " with glad " technology, and it is in the realization of whole technique system.
CAR middleware platform (CAR member operation platform) is the level of abstraction of operating system, and operating system realizes by the CAR component technology, and various member services are provided, and various member services are registered as the name service on the CAR middleware platform.Naming service mechanism belongs to the part of CAR component technology, and the CAR component technology provides a kind of issue by naming service mechanism, obtains, and uses the method for CAR member, and the name service is under the jurisdiction of the user interface part of CAR component technology.Name service be a kind of be the service of sign with the character string, it is defined as: the mode that obtains corresponding registered service interface by certain specific name.Service routine can be by API (the Application Programming Interface of operating system, API) function is to the service interface of operating system registration and unregistration oneself, and the user of service then can obtain the service specified interface by api function.
In sum, the invention provides the existing software product in the multiplexing original CAR middleware platform of a kind of simple and effective way, make the remote client on the Internet can be by being registered as the component object of name service on the standard network service agreement visit CAR middleware platform (CAR member operation platform), the developing instrument of having realized other support network services exploitation be multiplexing to the CAR member; And whole issuing process is finished automatically by CAR network service operation environment fully, and transparent fully to the component development person, the person additionally finishes any work also not need the component development, has reduced developer's workload.
Below also the present invention is described in further detail in conjunction with the accompanying drawings by embodiment.

Step 504, read the output parameter value in the parameter stack and return.
Referring to Fig. 6, it is applied each functional module of CAR network service agent program and a correlation schematic diagram in the specific embodiment shown in Figure 3.In the program operation process of reality, the realization of each functions of modules is to finish by dynamic establishment and the example that calls each module.
The applied module of CAR network service agent program comprises CAR network service agent module, HTTP packet read/write modules, SOAP packet read/write modules, coding/decoding module, CAR name service agent module, wsdl document generation module.Respectively each module is described below.
CAR network service agent module: major function is the mutual and Control Network service broker handling process with the webserver.Be used for the whole HTTP packet (packet of the download request of SOAP requested packets or wsdl document) that reception server sends over, and call other modules and handle, and the data that processing is returned are passed to server.
HTTP packet read/write modules: be used for handling and generate HTTP and ask (Request) and result (Response) packet; Handled and generate HTTP packet head by CAR network service agent module invokes; This module package the read-write operation of HTTP packet.Wherein http protocol itself is a standard WWW agreement.
SOAP packet read/write modules: be used for handling and generate SOAP and ask (Request), result (Response) and wrong (Fault) packet; Made by CAR network service agent module and to be used for handling and to generate the SOAP packet; This module is used to encapsulate the read-write operation of SOAP packet.Soap protocol itself also is standard WWW (World Wide Web, the World Wide Web (WWW)) agreement, follow the packing of soap protocol separates the packet format except needs, SOAP packet read/write modules also needs to safeguard the transformational relation between CAR data type and XSD (SOAP) data type: when resolving the SOAP packet, be the CAR data type with the XSD data type conversion of input parameter; When writing the SOAP packet, be the XSD data type with output parameter CAR data type conversion.
At last, consider efficient, be to handle (perhaps writing) while reading during this resume module SOAP packet, rather than once all data reads arrived internal memory while handling.The advantage that adopts this method is the space complexity that can farthest reduce processing procedure under the prerequisite of not obvious increase time complexity.
The coding/decoding module:
Be used for SOAP packet UTF-8, Base64, the coding and decoding of hex format text, wherein UTF-8 is the acquiescence coded system in the system.This module is decoded as the preceding initial data of coding with coded data, and perhaps the data that will transmit are encoded.For example, for transport-type is the parameter of Byte array, just the data content of storing in the array must be transmitted through being included in the SOAP packet after encoding.
CAR names service agent module:
Be used for the call request of transmission network service and obtain the agency service instance metadata; Called by CAR member Agent, be used to carry out mutual with CAR member example.This module is used to encapsulate all visits to CAR name services component example, that is to say, can be not directly in other any module and CAR name services component example produce any alternately, and the function of just calling this module realizes the visit to member name service.Make CAR member Agent not need directly and the CAR middleware platform carries out alternately by this module, thereby shielded the middleware platform characteristic, get ready for being transplanted to other middleware platform later on.
The wsdl document generation module:
This module is used for generating the WSDL format file according to the metadata of the CAR member example of input and webserver information.Specifically, the metadata of interface of CAR name services component example is used to generate the Type Scheme (type declarations) of WSDL document, PortType (port type), Message (message) part; The instance metadata of CAR name services component example is used to generate Port (port) (mainly being meant SOAP Address (the address)) part of WSDL document, adopt following naming rule in the present realization: " http://HOST[:PORT]/CARWSStubPath/SERVICE/INTERFACE.car ", wherein HOST represents Hostname, PORT represents the port that the webserver is monitored, CARWSStubPath represents the path that CAR network service agent program is stored, SERVICE represents CAR name services component title, and INTERFACE represents interface name; Webserver information is used to be provided with the procotol carrier information (http protocol) of Binding (binding) the part use of WSDL document, document Namespace (name space) and the soap protocol version number that uses, coded system (acquiescence is used the RPC mode).
The webserver:
On function, the webserver in this system should be the web application server of a standard, therefore can use in principle and comprise SMTP (Simple Mail Transfer Protocol, Simple Mail Transfer protocol), HTTP is at interior any type of network server, the standard interactive mode that the interactive mode of itself and CAR network service agent program is followed web application server and application program gets final product (for example CGI mode), in the application of reality, the simple HTTP webserver (here and the later content of this paper all discuss based on http protocol) of a componentization realizes based on having created with the CAR network service system of glad 2.0 operating systems, its main cause is: network service standard agreement SOAP and WSDL are the application layer protocols based on XML that is implemented on the procotol (for example HTTP etc.) that has been widely used, all must transmit data as carrier with one of these procotols by the remote request of the Internet, wherein at present by the most widely used be exactly http protocol; With also do not realize or transplant any general or Embedded http server on glad 2.0 operating systems; Orientate embedded OS as with glad 2.0 operating systems, do not need to realize a powerful http server.
The name services component that said method has been simplified on the issue middleware platform is the whole process of network service: on the one hand, need not existing member in the system is carried out any modification; On the other hand, the realization of this process only need move a webserver, need not to carry out complicated configuration.After finishing start-up course, the name services component object on all CAR middleware platforms all can be visited by the remote client by the standard network service agreement automatically.Realized support at present to WSDL and soap protocol.
For the wsdl document download request, according to the network service standard, the network service all should be carried out self-described by the WSDL service description file, and is published to the Internet.Present realization is finished by http protocol, and client can be downloaded wsdl document by HTTP URL form.For example: the HTTPURL form by " http://HOST[:PORT]/CARWSStubPath/SERVICE/INTERFACE.wsdl " is downloaded wsdl document.The WSDL of all name services component examples describes by CAR network service agent program and generates automatically when moving.
Be that an issue adder member example is the specific embodiment of network service below, at first need to create a CAR member example and be registered as the name service that shown in the following code, define an adder CAR member, this member has been realized interface ICalculator.
[
version(1.0)，
urn(calculator.dll)
]
component?calculator
{
interface?ICalculator{
HRESULT?Add([in]long?a，[in]long?b，[out]long*c)；
}
}
Suppose that the user is registered the CAR name service that is called calculator of running after fame (the API EzRegisterService that provides by the CAR naming service mechanism) with an example of this member.Then the user can be by HTTP URL: " http://HOST[:PORT]/CARWSStubPath/cal culator.wsdl " obtains the wsdl document of this service of description.Wsdl document thes contents are as follows:
