Problems solved by technology

Therefore, according to the type of remote service and remote object, it is necessary to build a local stub in advance to realize the transmission of the object, and it is impossible to realize the dynamic call to the remote service and the transmission of the remote object
In the Web2.0 environment, since the data is mostly semi-structured data, the structure and type of the object cannot be determined in advance, and the definition of the object and the data of the object cannot be completely independent

Embodiment Construction

[0018] The invention utilizes the extension function provided by the ATOM syndication format to realize the encapsulation of the remote object, and utilizes the ATOM release protocol to realize the operation of the remote object in the HTTP-based Web environment, thereby realizing the exchange of the remote object. The overall framework of the entire mechanism is as follows figure 1 .

[0019] Among them, the ATOM document parser is responsible for parsing and separating the structured extension nodes in the ATOM document. The ATOM document generator is responsible for serializing the information such as the object structure, type, and value provided by the mapping module into the ATOM structured extension node, and embedding it into the ATOM document. The mapping module uses the structured extended node information provided in the ATOM document parser to construct local or remote objects, and is also responsible for providing the structure, type, value and other information ...

Abstract

The invention discloses a remote object exchanging method based on an ATOM protocol, which utilizes the expansibility and the generality of the ATOM document format to carry out recursive packaging for a general object on the basis of the object packaging mode of the ATOM document format so as to eliminate the heterogeneity in different languages. On this basis, the object exchanging method based on the ATOM publishing protocol is provided, and the method can be realized with the JavaScript language in a web browser.

Description

technical field [0001] The invention relates to an object exchange method among distributed systems, in particular to a remote object exchange method adapted to the Web2.0 environment, which can be realized by a web page script language, and which takes semi-structured data and strong type language into account. Background technique [0002] With the development of the Internet, traditional desktop applications are gradually transformed into lightweight and easy-to-use Web applications. The Web2.0 and Mash-up concepts promoted by Ajax (Asynchronous JavaScript and XML) and other technologies have led to the rapid development of Web applications, and the user-friendliness and richness of content have been greatly improved. In the environment of Web2.0, the current application of data content stays at the blog and news level, and the main format of the data is RSS, JSON or Atom format. In the traditional remote exchange mechanism, for each remote service, there needs to be a c...
