In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
See Fig. 1, the present invention is based on the data transmission system of B/S, comprise data analysis system and data management system and database, wherein, data analysis system and data management system are respectively arranged with REST interface, for external call.
Described REST (transfer of Representational State Transfer declarative state) is a kind of design and development mode for network application, the complexity of exploitation can be reduced, the scalability of raising system, REST has five the most basic design concepts and criterions, one: all things on network are all conceptualized as resource (resource); Its two: the corresponding unique resource mark (resource identifier) of each resource; Its three: by general AUI (generic connector interface), resource is operated; Its four: can not resource identification be changed to the various operations of resource; Its five: all operations are all stateless (stateless), and wherein, REST adds three new criteria on original framework: unified interface, hierarchical system and as required code.
The core feature of REST framework style is exactly have a unified interface and unified interface between emphasis component, and in the REST world, things all on network is all conceptualized as resource, and REST is operated resource by general linker interface.The benefit of such design ensures that the service that system provides is all decoupling zero, greatly simplify system, thus improve interactivity and the reusability of system.And REST optimizes for the common situations of Web, REST interface is made to be designed to shift efficiently the hypermedia data of coarsegrain.
Described hierarchical system can improve the independence between various level, and for the complexity of whole system is provided with border, by encapsulating the service left over, make new server from the impact of legacy client, this also just improves the scalability of system.
The core of described code is as required that REST allows to expand client functionality.Such as, by downloading and performing the code of applet or form of scripts, client functionality is expanded.But this is while improving the system expandability, also reduce observability.So it is an optionally constraint of REST.
In addition, REST is the mode based on HTTP request, and HTTP has the convenience of firewall-penetrating, and REST develops simple, flexibly relative to Web Service, and this assures data can fast transport more, and development difficulty is little.
The concrete data flow that the present invention is based on the data transmission system of B/S is as follows:
Data analysis system obtains the data such as the function that calls of all current needs and parameter according to actual conditions, and distributes RSET interface to above-mentioned data, is then encrypted described data, by sending HTTP request, by encrypted data transmission to data management system.
Be decrypted this enciphered data while data management system receives above-mentioned enciphered data, and search the REST interface corresponding with enciphered data, the result according to searching corresponding RSET interface operates accordingly, specific as follows:
If search the REST interface less than correspondence, then return sky data and to the error of transmission of data analysis system reminder-data;
If find corresponding REST interface, then resolve the data of reception, obtain the data such as function and parameter that data analysis system transmits, data management system obtains with it corresponding data according to above-mentioned function and parameter from database, and the data of acquisition is loaded into function and runs function and obtain analyzing data.
After data management system obtains described analysis data, these analysis data stored in database, are distributed REST interface to these analysis data by one side on the other hand, and after being encrypted, by sending HTTP request, are transferred to data analysis system.
Data analysis system receives this HTTP request, and to this decrypt data, and search corresponding REST interface, the result according to searching corresponding RSET interface operates accordingly, specific as follows:
If search the REST interface less than correspondence, then return sky data to data management system, and data management system is pointed out;
If find corresponding REST interface, then resolve the data of reception, obtain analyzing data and showing.
