Embodiment
The method of downloading page information of the present invention and device thereof, a kind of service end can improve the speed of client downloads page info, and user experience is relatively good.
Below in conjunction with accompanying drawing specific embodiment of the present invention is done a detailed elaboration.
The method of downloading page information of the present invention like Fig. 1, comprises step:
The data connection request that S101, service end are sent according to client is set up and is connected with the data of said client; This data connect and can set up through WIFI or 3G network, and promptly client and service end can radio communications; Client can be that handheld electronic reader or portable terminal are such as mobile phone etc.;
The page request information that S102, service end are sent according to said client is obtained page info; At the various page infos that the service end client needs, service end can be obtained the page info of client needs according to the page request information that client is sent, and this page request information can be the chained address of webpage; Page info can be the book information of e-book and so on;
S103, lteral data in the page info that obtains and the location coordinate information of lteral data in the page are used the JSON protocol code;
JSON (JavaScript Object Notation) is a kind of data interchange format of lightweight; The JSON protocol description ultimate principle of page info is that each screen elements is described respectively; Every kind of style information such as positions of elements coordinate is in another pattern file; This is in order to present displaying contents and pattern separately; Make to the different shared contents of screen ability, conveniently switch pattern, introduce the pattern description document of similar CSS;
JSON has following these forms:
To as if unordered " ' name/value ' a to " set.An object finishes with " { " (left parenthesis) beginning, " } " (right parenthesis).": " (colon) of each " title " heel; Use ", " (comma) to separate between " ' name/value ' to ";
Array is the ordered set of value (value), and an array finishes with " [" (left bracket) beginning, "] " (right bracket).Use ", " (comma) to separate between the value;
Value (value) can be character string (string), numerical value (number), true, false, null, object (object) or the array (array) that double quotation marks brackets, and these structures can be nested;
Character string (string) is by the set of any amount Unicode character of double quotation marks encirclement, uses the backslash escape, and a character (character) i.e. is an independent character string (characterstring);
Numerical value (number) is also closely similar with the numerical value of C or Java;
Use the JSON protocol code, can realize the efficient communication of client and service end, avoid client to use built-in browser; The communication that is client and service end is adopted http protocol in application layer; Be the JSON agreement on the http protocol layer, when client during to page info of service end request, service end is used the JSON protocol code to the lteral data in the page info; After client is received lteral data; At first use JSON decoder decode data, obtain the string data of the page, can reduce according to the location coordinate information of lteral data in the page and obtain the page;
Because JSON protocol description data, succinct efficient, transmission speed is fast, is particularly suitable for the network data transmission of this hand-held terminal device of client;
S104, lteral data and the location coordinate information of lteral data in the page after will encoding send to client;
S105, said client are decoded to the lteral data and the location coordinate information of lteral data in the page that receive, show decoded lteral data according to the location coordinate information of decoded lteral data in the page.
In the specific implementation; Step S103 also comprises: if comprise picture in the page info that obtains; Service end is used the JSON protocol code with this picture with Base64 coding and with the location coordinate information of picture in the page, and the picture after will encoding and the location coordinate information of picture in the page send to client;
This moment, step S105 also comprised: said client is decoded to the picture and the location coordinate information of picture in the page that receive, shows decoded picture according to the location coordinate information of decoded picture in the page.Owing to can encode to the picture in the page info, then further improved data rate, increased user experience.
In order page info to be carried out the version protection, prevent that unauthorized user from arriving service end downloading page information, can carry out copyright protection to the page info of storage in service end.Even unauthorized user has been downloaded page info like this, owing to there is not encryption key, the page info e-book of still not opening has played the effect of copyright protection.For authorized user; Can obtain the occupancy permit file from service end through client; Contain the key behind the public key encryption of useful this client in the occupancy permit file, client can be used the private key deciphering of oneself, obtains encryption key; Thereby the deciphering page info obtains original page info and reads.The concrete realization as follows:
Before the page request information that said service end is sent according to said client is obtained page info; Lteral data and/or picture in the page info that said service end use encryption keys is obtained are according to the sign generation occupancy permit file of said encryption key and said client; And after the page request information of sending according to said client is obtained page info, said occupancy permit file is sent to said client; Be that service end is used encryption keys in advance to lteral data and/or picture in the page info of storage; After client and service end are set up data and are connected; Sign and encryption key according to this client generate the occupancy permit file, also this occupancy permit file are sent to client when lteral data after will encoding and/or picture send to client;
Said client is before decoding to the lteral data that receives and/or picture and lteral data and/or the location coordinate information of picture in the page; Decipher said occupancy permit file according to the private key of said client self; Obtain said encryption key, decipher lteral data and/or the picture that receives according to this encryption key.
Corresponding with the method for above-mentioned downloading page information, the invention also discloses a kind of device of downloading page information, like Fig. 2, it comprises: service end and client,
