Brief description of the drawings
Fig. 1 is the normalized system block diagram of DTO protocol datas described according to embodiments of the present invention；
Fig. 2 is the normalized method flow diagram of DTO protocol datas described according to embodiments of the present invention.
Specific embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground description.
As shown in figure 1, the present invention provides a kind of normalized system and method for DTO protocol datas, for solving association at present
The complexity of parsing is discussed, different agreement data requirement is melted into a kind of unified structure, the agreement number after will standardizing by the present invention
It is stored in element object according to according to tree, facilitates the lookup and extraction of data.So, other functions module is needed to use
During the protocol data, data directly can be read from E objects, without parsing original agreement packet again.
Element object is customized common data structure of the invention, for storing normalized protocol data.The data
Inside configuration includes three basic elements：Node text, attribute list, child list.Meanwhile, the data class of the subsidiary node
Type, parent information etc..
DTO full name Data Transfer Object, i.e. data transfer object, are commonly used in far call.It is first when using
Required each item data first is included with the object, then far call is carried out as single parameter, finally locally divided
Solve each item data.Relative to traditional Remote call method, DTO reduces the number of times of far call, improves the speed of data acquisition
Degree, reduces network bandwidth requirement.
How DTO protocol datas are resolved to element object structure by the detailed description of the invention, specific as follows：
As shown in figure 1, a kind of normalized system of DTO protocol datas described in embodiments in accordance with the present invention, for inciting somebody to action
DTO protocol datas resolve to element object structure, and normalized system includes type identification module and data resolution module；
The type identification module is for judging that packet is to ask also to be in response to and corresponding according to the call by result for judging
Process of analysis；
Specifically, being request data if the data header in packet is c..m；If the data header of packet
It is that r.. is then response data (wherein .. is two invisible characters of byte).Then by type (request/response), adjust respectively
Use request/response process of analysis.
It is request data if the data header in packet is c..m；If the data header of packet is r..
It is response data (wherein .. is two invisible characters of byte).Then by type (request/response), respectively call request/
Response process of analysis.
The solid data type that the data resolution module is used to parse in DTO protocol datas is solved into element object structure
In separating out the corresponding attribute of the DTO protocol datas type and adding the element object structure.
Further, the data resolution module includes object oriented processing module, data type judge module and data
Extraction module.
The object oriented processing module is used to obtain DTO object orienteds.Only request data just has DTO object names
Claim, acquisition modes are exactly to obtain the first character string behind request mark c..m, are added to the node text of currentElement object
In this；
The data type judge module is used to judge the data type of current markers.Such as S identification strings, its data structure
It is S+2 byte characters string length+string content into form；I identifies integer, and its data form of the composition is I+4 byte datas；T
Mark Boolean true；F mark Booleans false；Vt identify array, its data form of the composition be Vt+4 bytes membership+
Member's description etc..
The data extraction module is used for the data type drawn according to data type judge module, extracts the type
Then these data are set up element object structure by data and length respectively, and numerical value is assigned to the node text of the element object
Or attribute list (single number is assigned to node text, and compound type is assigned to attribute list), and using these element objects as
The child node of upper strata element object is assigned to the child list of father node.
Constantly repeat the above-mentioned type to judge and data extraction, until data are parsed, thus construct multiple E objects
Tree, so far, be formed general E object structure data.
As shown in Fig. 2 the invention also discloses a kind of normalized method of DTO protocol datas, for by DTO protocol datas
Element object structure is resolved to, is comprised the following steps：
1) judge that packet is request data package or response data packet, according to the corresponding resolution flow of structure choice for judging
Journey；
Specifically, being request data if the data header in packet is c..m；If the data header of packet
It is that r.. is then response data (wherein .. is two invisible characters of byte).Then by type (request/response), adjust respectively
Use request/response process of analysis.
2) the solid data type in DTO protocol datas is parsed into element object structure, parses the DTO agreements number
According to the corresponding attribute of type and add the element object structure.
Further, step 2) comprise the following steps：
2.1) when packet is request data package, DTO object orienteds are obtained first, then followed the steps below, work as number
When being in response to packet according to bag, directly follow the steps below.Only request data just has DTO object orienteds, and acquisition modes are just
It is to obtain the first character string behind request mark c..m, is added in the node text of currentElement object；
2.2) data type of current markers is judged；Such as S identification strings, its data form of the composition is S+2 byte characters
String length+string content；I identifies integer, and its data form of the composition is I+4 byte datas；T mark Booleans true；F is identified
Boolean false；Vt identifies array, and its data form of the composition is Vt+4 bytes membership+member's description etc..
2.3) according to step 2.2) data type judged extracts the type data and length, then to these data point
Do not set up element object structure, by numerical value be assigned to the element node text or attribute list (single number be assigned to node text
This, compound type is assigned to attribute list), and it is assigned to father node using these element objects as the child node of upper strata element object
Child list.
Constantly repeat the above-mentioned type to judge and data extraction, until data are parsed, thus construct multiple E objects
Tree, so far, be formed general E object structure data.
In sum, it is of the invention compared to general protocol analysis mode, DTO protocol datas parsing side of the invention
Method, can be normalized into unified form, it is thus possible to meet various protocols data processing needs by protocol data, and lifting makes
Convenience, while solving the complexity of conventional method, repeatability, reduces development cost.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
