Description
Technical field
The present invention relates to Internet technical field, relate in particular to a kind of method and system that in the Simple Object Access Protocol soap message, reduce Payload.
Background technology
Simple Object Access Protocol SOAP (Simple Object Access Protocol) is one can allow object mutual industry standard under interactive environment.The original intention of SOAP design is in order to carry out object interaction on the internet, increase the function of remote procedure call RPC (RemoteProcedure Call) in traditional network service.Soap message is to adopt expandable mark language XML (ExtensibleMarkup Language) coding, and the W3C of world wide web alliance tissue is strict with unified to definition XML NameSpace and XML coding rule.
Soap message is made up of following several parts:
1) the XML data is appointed as the envelope Envelope element of soap message.
2) contain the header Header element of the confession selecting for use of header.
3) contain the mandatory message body Body element of requirement and response message.
4) for the wrong Fault element selected for use, if make mistakes during processing messages, it will provide relevant this wrong information.
SOAP mainly uses the transfer mechanism of requests/response messages, and by traditional method, the SOAP application program is packaged into the soap message of HTTP message by the Internet exchange.The SOAP request can be used as HTML (Hypertext Markup Language) HTTP POST (transmission) message or HTTP GET (obtaining) message sends, response then can be used as the http response of standard and obtains, and employed content Content type is text/xml (xml of pure words pattern), application/xml (using the xml of pattern) or application/soap+xml (using the soap+xml of pattern) normally.
The SOAP of current service Network Based is encoded into XML to whole SOAP Payload to send.Described Payload is meant the data of soap message transmission.Design based on XML is that digital coding is complicated nested structure, and according to common mode it is sent by http protocol as character data.
But prior art has the following disadvantages:
At first, along with request and response become increasingly complex, the SOAP Payload that transmits on " soap:Body " element is also increasing.In response message, carry a large amount of information, will inevitably cause generating a huge XML file, and each labelled element in the XML structure has also contained the information such as title and type except the target information of reality.With regard to the form of XML, Payload is not done special coding, sends as a simple character string;
Secondly, concerning the network service that becomes increasingly complex, the SOAP Payload structure of transmitting in " soap:Body " element also becomes increasingly complex.Because many parameter codings must be become a plurality of structures and minor structure, thereby formed the very dark XML tree format of nested degree, along with the level of XML data organization is more and more, in analysis and recover data values and the operand of using when handling also increasing.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method and system that reduce Payload, and these method and system can reduce the Payload of simple object access protocol message, reduces the complexity of Payload.
The objective of the invention is to be achieved through the following technical solutions:
The invention provides a kind of method that reduces Payload, comprising: 1) the simple object access protocol message data are used abstract syntax symbol syntactic representation; 2) the simple object access protocol message data reduction with abstract syntax symbol syntactic representation becomes binary data; 3) embed simple object access protocol message after converting binary data to text formatting.
Further, described step 2) comprise that the use Basic Encoding Rules becomes binary data with the simple object access protocol message data reduction.
Further, described step 2) comprise that the use Packed Encoding Rules becomes binary data with the simple object access protocol message data reduction.
Further, be specially use BASE64 coding in the described step 3) and convert binary data to text formatting.
Accordingly, the invention provides a kind of system that reduces Payload, comprising: memory cell and converting unit; Memory cell is used to store simple object access protocol message; Converting unit is used to change simple object access protocol message; Converting unit with abstract syntax symbol syntactic representation, and is converted into binary data with the simple object access protocol message data of memory cell, embeds simple object access protocol message after converting text formatting again to.
Further, converting unit comprises that the use Basic Encoding Rules becomes binary data with the simple object access protocol message data reduction.
Further, converting unit comprises that the use Packed Encoding Rules becomes binary data with the simple object access protocol message data reduction.
Further, converting unit is specially and uses the BASE64 coding to convert binary data to text formatting.
Above technical scheme as can be seen, the present invention has following effect:
At first, simple object access protocol message The data XML form in the aforementioned prior art, Payload is not done special coding, occupy very large space, and the present invention is with simple object access protocol message data abstract syntax symbol syntactic representation, and be converted into binary data, embed simple object access protocol message after converting binary data to text formatting again, thereby the space that Payload is occupied significantly reduces;
Further, Simple Object Access Protocol The data XML form in the aforementioned prior art, Payload structure more complicated, structure is nested deep, and the present invention takes abstract syntax symbol syntactic representation with the simple object access protocol message data, is to adopt unidirectional navigation form, and nested degree is low, thereby reduced the complexity of Payload, operand reduces when also making deal with data.

Embodiment
Simple Object Access Protocol SOAP uses available two kinds of pattern work, a kind of document mode that is called as, and a kind of is remote procedure call RPC (Remote Procedure Call) pattern.
Below be a minimum soap message of document mode:
| <xml version="1.0">// version information<soap:Envelope //，xmlsoap xmlns:soap="http://www.w3.org/2001/12/soap-envelope"><soap:Body>// message body element carries and uses self-defining soap message<m:GetItemsLimitByPrice xmlns:m="urn:Prices"><m:Price>100</m:Price>// this node represents that this soap message wants the GetItemsLimitByPrice interface of access server, parameter name is Price, and parameter value is 100</m:GetItemsLimitByPrice></soap:Body></soap:Envelope> |
Below be a minimum soap message of remote procedure call RPC pattern:
| <xml version="1.0">// version information<soap:Envelope //，xmlsoap xmlns:soap="http://www.w3.org/2001/12/soap-envelope"><soap:Body>// message body element carries and uses self-defining soap message<m:GetItemsLimitByPrice xmlns:m="urn:Prices"><m:Price xsi:type="xsd:int">100</m:Price>// this node represents that this soap message wants the GetItemsLimitByPrice interface of access server, parameter name is Price, and parameter value is 100</m:GetItemsLimitByPrice></soap:Body></soap:Envelope> |
The meaning that above-mentioned simple soap message is represented is, the transmit leg of message is thought this remote interface of GetItemsLimitByPrice of far call message receiver, and a parameter is provided is 100.
Can see that soap message is that the XML data are the characters through coding, and have a level recurrence representation with the expandable mark language XML coding.The objective of the invention is from Payload, to remove extra redundant information again, just can dwindle its shared space greatly by introducing the binary coding of character data.Simultaneously, the XML data transaction is become unidirectional navigational structure, and do not use the recurrence representation, just simpler in the decoding of receiving terminal like this.
A kind of method and system that reduces Payload provided by the invention, its core concept is: 1) the simple object access protocol message data are used abstract syntax symbol syntactic representation; 2) the simple object access protocol message data reduction is become binary data; 3) embed simple object access protocol message after converting binary data to text formatting.
Seeing also Fig. 1, is the method flow diagram that the present invention reduces Payload, comprises step:
A1) the simple object access protocol message data are used abstract syntax symbol syntactic representation;
The first step of the present invention is abstract syntax symbol ASN.1 (the Abstract Syntax notation one) grammer that the data reduction of Simple Object Access Protocol soap message is become equivalence.
Soap message is that the XML data are the characters through coding with the expandable mark language XML coding.The basic composition of XML data has label, attribute and value, and these data are all represented with pure character.Because the standard of network service is disclosed, therefore be that each element all adds label and attribute is unnecessary.Why need such data, because this is a kind of means that keep structure and the information that transmits relevant value, and ASN.1 can satisfy these attributes fully.In ASN.1 mechanism, element term information also can be removed in the lump, and can encode to type information with data still less.
Abstract syntax symbol ASN.1 is a standard that involvement aspect is very wide, and it almost can be used for representing any data, for example binary data of integer, floating number, random-length, character and character string etc.Simultaneously, it can also represent the structure that nested degree is very dark easily in the mode of module.The unidirectional navigation of ASN.1 The data of coding makes its easier decoding of data than the multidirectional tree-shaped navigation of representing with XML of employing, thereby has reduced the complexity of extracting useful information.So-called unidirectional navigation is meant that data message is linearly aligned, and like this, decoding is exactly unidirectional, there is no need to move forward and backward.So-called multidirectional tree-shaped navigation is meant that data message divides into groups according to the node of tree, visit the relevant data of certain node, can conduct interviews by a unique path, but when will retrieving relevant information, this representation need on a plurality of directions, move around, so during the informational needs decoding processing of representing like this, need more amount of calculation.
Minimum soap message with above-mentioned listed RPC pattern is an example, and the interface that this soap message will be visited is GetItemsLimitByPrice, and it needs the parameter of an integer type, and parameter is called price.It is used abstract syntax symbol ASN.1 syntactic representation, specific as follows:
| Module-prices DEFINITIONS AUTOMATIC TAGS::=//a module BEGIN defining in the ASN.1 // begin defines the parametric description END that label G etItemsLimitByPrice::={getItemLimitByPrice Price} Price::=INTEGER // interface name and this interface needs // ends and defines label |
Here, the major part of soap message, promptly " soap:Body " element has been converted into abstract syntax symbol syntactic representation.
A2) the simple object access protocol message data reduction with abstract syntax symbol syntactic representation becomes binary data;
The present invention uses Packed Encoding Rules PER (Packed Encoding Rule) or Basic Encoding Rules BER (Basic Encoding Rule) that the simple object access protocol message data reduction is become binary data.
In case the expression of abstract syntax symbol ASN.1 is available, corresponding data just can be encoded according to BER and PER, X.690, these coding rules have detailed description in (BER) and ITU-TX.691 (PER) file at the ITU-T of International Telecommunications Union, use these rules, can convert simple character data to binary data with the XML coding.
Use Packed Encoding Rules PER or Basic Encoding Rules BER to become binary data specific as follows the above-mentioned simple object access protocol message data reduction that has been converted into the abstract syntax symbolic representation:
| ASN.1 syntax: //ASN.1 representation Price:=INTEGER //Price is that (value: // parameter is Price to an integer type Input, and its value is 100 Price:=100 (10 system) Output (encoded data): the binary data of output behind the // process coding |
| BER (16 system) 02 01 64 is BER (2 system) 00,000,010 00,000,001 01100100 PER (2 system) 1100100 |
Need to prove, the present invention uses Basic Encoding Rules BER or Packed Encoding Rules PER that the simple object access protocol message data reduction is become binary data but is not limited thereto, and those skilled in the art also can adopt other coding rules that the simple object access protocol message data reduction is become binary data.
A3) embed simple object access protocol message after converting binary data to text formatting.
The present invention uses the BASE64 coding that the binary number data transaction is become to embed SOAP/XML message behind the character text form that shows.
Because pure binary data can not be used with the XML character data that sends as soap message, therefore require to use the BASE64 coding data transaction to be become the US ASCII or the iso-8859-1 text formatting character set of standard.
To carrying out BASE64 coding by the ASN.1 coded data in the above-mentioned example:
| Carrying out BASE64 according to BER 00,000,010 00,000,001 01100100 is encoded to: AgFk carries out BASE64 according to PER 1100100 and is encoded to: yA== |
Need to prove that the present invention uses the BASE64 coding that the binary data data transaction is become text formatting but is not limited thereto, those skilled in the art also can adopt other codings that the binary data data transaction is become text formatting.
Can directly embed SOAP/XML message through the BASE64 coded data as character string.According to ASN.1 sentence structure coding, can use SOAP type of coding " soap:encodingStyle " attribute of standard in order to represent embedded data.The W3C of world wide web alliance organization prescribed SOAP type of coding attribute is generally used for defining the data type in the XML document of having used this attribute.This attribute can appear in the middle of any one soap message element, is applied in the content of its element or daughter element.
Through after the whole transfer process, soap message converts following form to:
| ＜xml version=" 1.0 "〉// use BER coding soap:Body content＜soap:Envelope xmlns:soap=" http://www.w3.org/2001/12/soap-envelope " 〉 |
| <soap:Body><m:GetItemsLimitByPrice xmlns:m="urn:Prices" soap:encodingStyle="urn:ASN.1BER">// data after this message content uses BER coding AgFk // carry out BASE64 coding are described</m:GetItemsLimitByPrice></soap:Body></soap:Envelope><xml version="1.0">// use PER coding soap:Body content<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope"><soap:Body><m:GetItemsLimitByPrice xmlns:m="urn:Prices" soap:encodingStyle="urn:ASN.1PER">// data after this message content uses PER coding yA==// carry out BASE64 coding are described</m:GetItemsLimitByPrice></soap:Body></soap:Envelope> |
As can be seen, the soap message of representing with XML adopts the inventive method can effectively reduce Payload, is 41 bytes before the soap message conversion, and has only 4 bytes after the conversion.Concrete comparable situation is as follows:
| The situation that the original data of representing with XML are not converted:<m:Price xsi:type="xsd:int">100</m:Price>41bytes, after (byte) converts ASN.1 representation: Price:=100 process BER or PER coding to: the BER coding, (2 system) 00,000,010 00,000,001 01100100 3bytes, (byte) PER coding, (2 system) 1100100 7bits, (bit), (about 1 byte) |
| BER or PER coded data are carried out the BASE64 coding: according to the BER digital coding be: AgFk 4bytes (byte) according to the PER digital coding is: yA==4bytes (byte) |
During if magnanimity XML data are encoded, it is more obvious to adopt the inventive method to reduce the effect of Payload.
Need to prove that though through such conversion, the soap message that forms remains and meets the W3C proposed standard fully, can transmit by HTTP as usual.
In addition, the transmission of messages after the conversion is behind receiving terminal, and receiving terminal obtains the value of Payload at first the BASE64 data decode that extracts thereby according to the specification of ASN.1 data are further decoded then from soap message.Decode procedure is as follows:
| decode_soap_body ( ) //soap begin // if ( soap:encodingStyle present ) then //soap:encodingStyle if ( soap:encodingStyle eq”urn:ASN.1BER” ) then //urn:ASN.1BER decode_content_using_BASE64 ( ) //BASE64 continue_decode_using_ASN1BER ( ) //ASN1BER else if ( soap:encodingStyle eq”urn:ASN.1BER” ) then //urn:ASN.1PER decode_content_using_BASE64 ( ) //BASE64 continue_decode_using_ASN1PER ( ) //ASN1PER else // follow_character_decoding ( ) else //soap:encodingStyle, follow_character_decoding ( ) end // |
Above-mentioned a kind of method that reduces Payload provided by the invention is described in detail, corresponding, the invention provides a kind of system that reduces Payload, see also the system schematic that Fig. 2 the present invention reduces Payload.
Soap message is that the XML data are the characters through coding with the expandable mark language XML coding.The basic composition of XML data has: label, attribute and value, these data are all represented with pure character.Because the standard of network service is disclosed, therefore be that each element all adds label and attribute is unnecessary.Why need such data, because this is a kind of means that keep structure and the information that transmits relevant value, and ASN.1 can satisfy these attributes fully.In ASN.1 mechanism, element term information also can be removed in the lump, and can encode to type information with data still less.
Abstract syntax symbol ASN.1 is a standard that involvement aspect is very wide, and it almost can be used for representing any data, for example binary data of integer, floating number, random-length, character and character string etc.Simultaneously, it can also represent the structure that nested degree is very dark easily in the mode of module.The converting unit 202 of system of the present invention is with the simple object access protocol message data of memory cell 201 abstract syntax symbol ASN.1 syntactic representation, the unidirectional navigation of ASN.1 The data, make its easier decoding of data, thereby reduced the complexity of extracting useful information than the multidirectional tree-shaped navigation of representing with XML of employing.So-called unidirectional navigation is meant that data message is linearly aligned, and like this, decoding is exactly unidirectional, there is no need to move forward and backward.So-called multidirectional tree-shaped navigation is meant that data message divides into groups according to the node of tree, visit the relevant data of certain node, can conduct interviews by a unique path, but when will retrieving relevant information, this representation need on a plurality of directions, move around, so during the informational needs decoding processing of representing like this, need more amount of calculation.
Converting unit 202 comprises uses Basic Encoding Rules BER or Packed Encoding Rules PER that the simple object access protocol message data reduction is become binary data.
Need to prove, the present invention uses Basic Encoding Rules BER or Packed Encoding Rules PER that the simple object access protocol message data reduction is become binary data but is not limited thereto, and those skilled in the art also can adopt other coding rules that the simple object access protocol message data reduction is become binary data.
Because pure binary data can not be used with the XML character data that sends as soap message, so converting unit 202 comprises and embeds simple object access protocol message after using the BASE64 coding that the binary data data transaction is become text formatting.
Need to prove that the present invention uses the BASE64 coding that the binary data data transaction is become text formatting but is not limited thereto, those skilled in the art also can adopt other codings to convert binary data to text formatting.
