Embodiment
The present invention is based on the request-response model of HTTP(Hypertext Transport Protocol), and relies on increase income module and message-oriented middleware of HTTPD and realize the function that service end is required.Here said " request " refers to the HTTP message that sends from client, and " response " refers to from service end and return HTTP message to the Request Processing of client.
Core concept of the present invention is: be written as the WEB application quantity body customization server script command statement of embedded device and be stored in service end according to predefined fairly simple syntax rule; When service end receives the HTTP request message, carry out mutual resource file and export target file according to this message and background function module to carry out corresponding service processing or analysis request, then result and/or file destination are returned to client.
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In the present embodiment, the structure of embedded script generation module comprises as shown in Figure 1: http protocol parsing module, data interaction module and script parsing module, wherein,
The http protocol parsing module is used to resolve the received HTTP request message of described service end, for data interaction module and script parsing module provide the processing foundation;
The data interaction module is used for carrying out data interaction according to the parsing content and the service end corresponding background functional module of HTTP request message, carries out corresponding service by this background function module and handles and return result;
The script parsing module is used for according to the parsing content of HTTP request message client institute of institute requested resource file being resolved the export target file.
In the present embodiment, the method that embedded script generates may further comprise the steps as shown in Figure 1:
Before handling, must write the server script command statement and be stored in service end according to predefined grammer, dispose above-mentioned embedded script generation module in service end simultaneously; This syntax rule has defined embedded script command statement and has been made up of beginning identifier, command word, parameter, end identifier, wherein begin the start-stop that identifier and end identifier are used to define order, in the present embodiment, adopt "＜? " "?〉" be identifier and end identifier to start with respectively; Also can nested another command statement in the command statement, for example＜? command word ...＜? command word ...? ...?; Command word is the part of most critical in the order, in order to operation and the employed method of determining to carry out, the number of parameters of different command words is different, even identical command word is under different condition judgment, number of parameters also can be different, in the present embodiment, command word comprises get, mget, objget, setvar, setvaronce, if, include, echo, error.
201, in service end, its HTTPD module of increasing income is carried out activity as a resident process, and the HTTP/HTTPS port is monitored;
202, increase income module when listening to the HTTP request that sends from client as HTTPD, the HTTP request message is decomposed one by one and pass to embedded script generation module as environmental variance decomposing the result who comes out; The HTTP request message is made up of request row, request head, null and four parts of request msg.
203, the http protocol parsing module of embedded script generation module is resolved the HTTP request message, determines the type of HTTP request and gets parms according to the type according to environmental variance; When request type was the GET mode, required parameter was all directly obtained from environmental variance; When request type was the POST mode, a parameters needed part was obtained from environmental variance, and another part obtains from the standard input;
Above-mentioned GET mode and POST mode are two kinds of the most frequently used request types; When client will read document from server, use the GET mode usually, require server that the resource of URL location is placed on the data division loopback of response message to client; When client provides information can use the POST mode more for a long time to server, the POST mode is encapsulated in required parameter in the HTTP request msg, can transferring large number of data.
204, according to the parameter of obtaining, the data interaction module of embedded script generation module is passed through message-oriented middleware, carry out data interaction with corresponding background function module, carry out corresponding service processing by this background function module, and obtain the result of success/failure of returning from message-oriented middleware; Perhaps, according to the parameter of obtaining, the script parsing module of embedded script generation module is resolved and the export target file client institute requested resource file.
205, the HTTPD of the service end module of increasing income generates HTTP request response message and above-mentioned result and/or file destination is packaged in wherein, and client is given in loopback afterwards.
In the above-mentioned steps 204, before resource file is resolved, need earlier resource file to be resolved to be put into buffer zone, because the limited storage space system of buffer zone, when the size of resource file to be resolved surpasses buffer zone big or small, this resource file can be divided into a plurality of parts and handle; When resolving, find out the embedded script command statement in the resource file to be resolved earlier, resolve back output for the embedded script command statement in the resource file, for then former state output of the non-embedded script command statement in the resource file; As shown in Figure 3, this process may further comprise the steps:
301, the script parsing module reads resource file to be resolved from buffer zone, because resource file belongs to source file, so wherein may comprise a large amount of embedded script commands;
302, from the original position of resource file to be resolved, one by one the beginning identifier in the chracter search resource file "＜? " Judge whether to search the beginning identifier "＜? ", if search, then execution in step 303; If not search, then execution in step 306;
303, from the beginning identifier that searched "＜? " the position begin the end identifier in the search text content "?〉"; Judge whether to search end identifier "?〉", if search, then execution in step 304; If do not search, then execution in step 307;
304, from search nearest beginning identifier "＜? " the position begin, search beginning identifier between an end identifier that searches "?〉" "＜? ", if search, then execution in step 305; If do not search, then execution in step 308;
305, from searching the position of nearest end identifier "?〉", the end identifier in the search text content "? ", if search, then return execution in step 304, if do not search, then execution in step 307;
306, call output function all resource file former state output;
307, call output function first begin identifier "＜? " content of text former state output before, and read untreated resource file again and fill up buffer zone, and be back to 302;
308, call analytical function and resolve beginning and end identifier matching complete and the longest script command statement that is found, and content is resolved in output.If resolve successfully, then read the resource file content that has been untreated again and fill up buffer zone, enter the text resolution of next round; If resolve failure, then output error message.
In the above-mentioned steps 308, the parsing of script command statement is comprised following step:
Step 1, command word and parameter in the whole script command statement are separated, be stored in the structure.For example, for the script command statement＜? echo $var:test?, echo wherein is a command word, the meaning of expression is the value of query interface; Var:test represents a undefined or defined variable for the parameter of order echo.
Step 2, according to the command word of being obtained in the step 1, enter corresponding command word and handle in the function;
Step 3, enter after corresponding command word handles function,, carry out following operation according to the parameter of being obtained in the step 1:
1) whether judges in the parameter nested sub-script command; If be nested with sub-script command, then former state is exported whole sub-script command statement;
2) judge whether there is variable in the parameter,, then variable is replaced if there is variable; If there is not variable, then skip processing;
Wherein, variable has two kinds: first kind is the User Defined variable, and second kind is the variable that system generates automatically.For the User Defined variable, generally can directly replace processing, for example, for custom variable var:test, script command＜? echo$var:test? in, can directly replace with 1 (value of supposing variable var:test here is 1); For the automatic variable that generates of system, because being system, this variable generates automatically, so this variable is represented that with adding two numerals wherein first digit is expressed as the nested number of plies, which variable second digit is expressed as, and for example expression is when the 2nd variable of anterior layer.
After step 4, script command were replaced and finish, this script returned with the form of whole text, because this text may also include script command, needed to be continued to resolve.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
