Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described embodiment is only some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of the application protection.
Referring to Fig. 1, it illustrates the flow process of the file online browse embodiment of the method 1 that the application provides.The present embodiment is applied on the server, and server-side is previously provided with picture library, and this picture library is properly termed as default picture library.
Preset that what preserve in picture library is the picture after the file page of file converts.Specifically, file includes some chapters and sections, and each chapters and sections are made up of some file pages, before enforcement, each file page is converted into picture and is saved in the word content in default picture library, in the content of picture and file page.Such as, certain file comprises 3 chapters and sections, and each chapters and sections comprise 5 file pages, then 15 file pages are converted into 15 pictures and are saved in default picture library.
It should be noted that a default picture library can only preserve the picture of a file translations, or, a default picture library can preserve the picture of multiple file translations.
Such as Fig. 1, the present embodiment can specifically include step S101～step S103.
Step S101: if receiving the chapters and sections browse request of the file destination that client sends, extracts target chapters and sections mark from chapters and sections browse request；Wherein, file destination can be divided into some chapters and sections, and each chapters and sections comprise some file pages, and each file page is converted into picture and is saved in default picture library.
Wherein, client can send the chapters and sections browse request of certain file to server, comprises the chapters and sections mark of certain chapters and sections of this document in chapters and sections browse request.Chapters and sections browse request represents that client request browses the content of certain chapters and sections of certain file.For the ease of describing, this document is called file destination, these chapters and sections mark is called that target chapters and sections identify.Certainly, the file page of file destination has been converted into picture and is saved in default picture library.
After server receives the chapters and sections browse request that client sends, therefrom extract target chapters and sections mark, and perform step S102.
Step S102: in default picture library, searches the Target Photo that target chapters and sections mark is corresponding.
Wherein, if each default picture library only preserves the picture after a file translations, then the default picture library that whois lookup file destination is corresponding, in this default picture library, search the picture that the target chapters and sections mark of this file destination is corresponding.If including the picture after multiple file translations in default picture library, then server needs in default picture library, picture that is that search file destination conversion and that be target chapters and sections mark correspondence.For the ease of describe, by whois lookup to picture be called Target Photo.
The Target Photo corresponding in order to search target chapters and sections mark, it is necessary to pre-set the corresponding relation between chapters and sections mark and picture.
Wherein, this corresponding relation can be the corresponding relation between the first pictures of the chapters and sections of chapters and sections mark and the mark expression of these chapters and sections.Such as, certain chapters and sections is designated 1.1, and what these chapters and sections mark represented is chapter 1 first segment, chapter 1, first segment comprises 5 file pages, thus, these chapters and sections comprise 5 pictures in default picture library, and corresponding relation can be the corresponding relation of the first pictures in chapters and sections mark 1.1 and 5 pictures.
Or, this corresponding relation can also be the corresponding relation between whole pictures of the chapters and sections of chapters and sections mark and the mark expression of these chapters and sections.Still being designated example with above-mentioned chapters and sections, the corresponding relation of this kind of form is, the corresponding relation of chapters and sections mark 1.1 and 5 pictures.
In force, multi-form corresponding relation, then the Target Photo found is also different.In the first corresponding relation above-mentioned, the Target Photo found is the first pictures that the chapters and sections that these chapters and sections mark represents comprise, and in the second corresponding relation, the Target Photo of lookup is whole pictures that the chapters and sections that these chapters and sections mark represents comprise.The Target Photo quantity found is different, has different implementation results, describes in detail more below, does not repeat herein.
Step S103: Target Photo is returned client, displays for client.
Wherein, Target Photo previous step found returns to client, and client can be shown to user, it is achieved the online browse of user.
From above technical scheme, this application provides a kind of file online browse embodiment of the method, the present embodiment is applied on the server, server receive that client sends to after the browse request of certain chapters and sections of certain file, the browse request of these chapters and sections is extracted chapters and sections mark, and in default picture library, search the picture that these chapters and sections mark is corresponding, picture is the picture that the file page of these chapters and sections in this document is converted into, and the picture that will find returns client, shows for client.Visible, the present embodiment can realize user's online browse file, and the file browsed is the file after being converted into picture format, and the file of picture format can effectively prevent word content to be replicated, thus avoiding the propagation of file.
File destination in above file online browse embodiment of the method can be but not limited to normative document, normative document is usually to instruct or certain industry behavior of specification and the file formulated, such as, " marine wind electric field steel structure anti-corrosion technical specification " defines anticorrosive measure, anticorrosion requirement, inspection and acceptance criteria etc..And for example, " power engineering construction project safety in production standard convention and rating scale up to standard " defines the Safety Production Target of power engineering construction project, organization and responsibility, safety in production input, laws and regulations and safety management system, emergency management and rescue, accident report investigation and process etc..
By the explanation of above step S102 it can be seen that chapters and sections mark is different from the corresponding relation of picture, then the picture number returning to client also differs.If according to corresponding relation, for client return is that chapters and sections identify corresponding first pictures, owing to the picture number returned is less, the duration expended is shorter, then client can get first pictures quickly, and displays in time, the waiting time of user, better user experience can be reduced.If after user has browsed first pictures, it is desirable to continue to check follow-up picture, it is possible to by page turn over operation, to the picture that server request is follow-up.Further, generally, user needs only to check the content of certain chapters and sections previous section, without the content of the aft section browsing these chapters and sections, therefore, and the wasting of resources that this kind of mode can avoid the whole pictures returning these chapters and sections to cause.
If according to corresponding relation, what return for client is whole pictures of the chapters and sections that chapters and sections mark represents, then can reduce user end to server and send the number of times of follow-up browse request, follow-up browses thus user friendly.
Certainly, may also take in above two mode and later technical scheme, namely returning the first pictures of the chapters and sections that chapters and sections mark represents and return several pictures after this head pictures simultaneously, wherein, the particular number of several pictures can be arranged flexibly according to practical situation.Such as, chapters and sections are designated 1.1, comprise 5 pictures, then can return the 1st pictures and 2 follow-up pictures in the chapters and sections that these chapters and sections mark represents.
In order to realize above technique effect, this application provides online browse embodiment of the method 2.The present embodiment is equally applied on server, as in figure 2 it is shown, the present embodiment can specifically include step S201～step S203.
Step S201: if receiving the chapters and sections browse request of the file destination that client sends, target chapters and sections mark is extracted from chapters and sections browse request, wherein, target chapters and sections are designated Target Photo numbering, and Target Photo is numbered the picture number of the first pictures of the chapters and sections that target chapters and sections mark represents.
In the present embodiment, the numbering that concrete form is picture of the target chapters and sections mark that server extracts from chapters and sections browse request.For the ease of describing, it is possible to the numbering of the picture extracted is called that Target Photo is numbered.
It should be noted that this Target Photo is numbered the numbering of the first pictures of the chapters and sections that these target chapters and sections mark represents.Such as, client wants the content browsing chapter 2 first segment, chapter 2 first segment comprise 3 convert after picture, and 3 the picture number of pictures be followed successively by 15,16 and 17, the Target Photo comprised in the chapters and sections browse request that then client sends is numbered 15, thus server can extract Target Photo numbering 15 from chapters and sections browse request.
Step S202: in default picture library, searches the picture of picture corresponding to Target Photo numbering and picture number predetermined number after Target Photo is numbered, using the picture that finds as Target Photo.
In the present embodiment, the picture preset in picture library has picture number, and each picture number sorts successively, say, that the picture after the file page conversion of file destination has picture number, and sorts successively according to the sequence of file page.
After server extracts Target Photo numbering, in default picture library, search the picture that Target Photo numbering is corresponding.Be numbered the picture number of the first pictures of certain chapters and sections due to Target Photo, then the picture found is the first pictures of these chapters and sections.It addition, server is except the first pictures searching these chapters and sections, it is also possible to search the picture of sequence predetermined number after this head pictures.Wherein, predetermined number is the numerical value pre-set according to practical situation, and the application is also not specifically limited.
Step S203: Target Photo is returned client, displays for client.
Wherein, the Target Photo found is returned client to show.
From above technical scheme, the file online browse embodiment of the method that the application provides, the picture of predetermined number after the first pictures of certain chapters and sections and this head pictures can be searched, picture after first pictures and first pictures being returned client show, so, first client can show first pictures, browse for user, and the picture after this head pictures of buffer memory, when user's page turning, it is possible to the picture after loading the first pictures of local cache displays.The present embodiment both ensure that client displayed for a user the efficiency of first pictures, also ensure that user's display efficiency when follow-up browsing.
It should be noted that the picture of the predetermined number after first pictures can belong to different chapters and sections from first pictures.
In actual applications, the Target Photo that server returns can be the Target Photo after overcompression and encryption.It is to say, in each file online browse embodiment of the method above-mentioned, Target Photo is returned client, the specific implementation displayed for client may comprise steps of A1.
Step A1: obtain compressed package after compression goal picture, and return client after compressed package is encrypted, display for client.
Specifically, using any one file compression method existing, Target Photo being compressed, thus obtaining compressed package.It is possible to further compressed package is encrypted, the password of encryption can be the account of user login services device, or the device identification of the client with this account relating, or random number etc. has the password of uniqueness.
Above in each application file online browse embodiment of the method on the server, the chapters and sections browse request that the client received sends is all the chapters and sections browse request generated when client obtains bibliographic structure.Specifically, client shows this bibliographic structure after obtaining bibliographic structure, and user can select certain chapters and sections in bibliographic structure, is sent the chapters and sections browse request of these chapters and sections by user end to server.
Certainly, server is before receiving the chapters and sections browse request of certain file, it is possible to receive the browse request to this document, thus the bibliographic structure of this document is returned client.
Specifically, as it is shown on figure 3, this implementation is on the basis of above-mentioned file online browse embodiment of the method 1, it is also possible to include step S301～step S303.
Step S301: if receiving the browse request of the file destination that client sends, extracts the file destination mark of file destination from browse request.
Wherein, if user wants to browse certain file, it is possible to sent the browse request of this document by user end to server, return this document for request server.Server is after receiving this browse request, first from browse request, extract the mark of this document, for the ease of describing, this document is called file destination, this file destination can be the file destination in each file online browse embodiment of the method above-mentioned, it is also possible to be alternative document.It addition, the mark of file is properly termed as file destination mark.
Step S302: search the bibliographic structure that file destination mark is corresponding, and in default picture library, according to the corresponding relation between the file identification pre-set and browsing pictures, search the target browsing pictures that file destination mark is corresponding；Wherein, target browsing pictures comprises the picture of the predetermined number after the first pictures of file destination and first pictures.
In this implementation, picture that the first file page of what server returned is this document converts and the bibliographic structure of this document.Wherein, generally, first file page can be the strip of paper used for sealing page of file.
Therefore, before enforcement, the bibliographic structure of correspondence is set for file in advance.Bibliographic structure can include the title of catalogue, the title of catalogue can show in client, to facilitate user to understand, which chapters and sections file comprises, and user can click certain chapters and sections in bibliographic structure, to trigger the execution of each file online browse embodiment of the method above-mentioned, so that picture corresponding to these chapters and sections of user being asked of server returns to client and show.
After server extracts file destination mark, in the bibliographic structure pre-set, search the bibliographic structure that file destination mark is corresponding.
From described above, server is except Returning catalogue structure, in addition it is also necessary to return the picture (headed by can being called for short pictures) that the first file page of file destination converts, therefore, server also needs in default picture library, searches the first pictures of file destination.So, first client can show the first pictures of this document.
In actual applications, usually, the strip of paper used for sealing page that first pictures is file that user browses to, next user will trigger page turn over operation in client, to continue to check follow-up file page.Therefore, client also needs to send the browse request to follow-up file page to server, will increase the waiting time of user, and browse efficiency is slower.
Therefore, after server receives the browse request to file, the picture of return not only includes first pictures, it is also possible to include the picture of predetermined number after first pictures.In order to realize this kind of technique effect, it is necessary to before enforcement, pre-setting the corresponding relation between file identification and browsing pictures, namely this browsing pictures needs the picture returned according to the browse request to file of client.Such as, the picture that the file identification of certain file 1 is corresponding includes three pictures after first pictures and this head pictures.
So, server just can identify according to file destination, searches the browsing pictures that this file destination mark is corresponding, i.e. target browsing pictures.Target browsing pictures not only comprises first pictures, also includes the picture of predetermined number after first pictures.
Step S303: bibliographic structure and target browsing pictures are returned client.
Wherein, the bibliographic structure of file destination and the browsing pictures return client of correspondence are shown by server.Certainly, first client can show the first pictures of file destination, when user triggers page turn over operation, then is shown successively by the picture of the predetermined number after this head pictures.
It addition, bibliographic structure can be shown in the side of client display interface with various forms such as suspension window, hide windows.Such as, the bibliographic structure of " 330kV～750kV overhead transmission line exploration specification " is shown in the side of the clients such as mobile phone, and after user clicks hidden icons, it is possible to bibliographic structure is hidden.
It addition, corresponding with the above-mentioned file online browse embodiment of the method being applied in server, present invention also provides the file online browse embodiment of the method being applied in client, explanation specific as follows.
Referring to Fig. 4, this application provides the flow process of the file online browse embodiment of the method 1 being applied in client.Client can be but be not limited to desk computer, portable notebook, mobile phone, PAD etc., client shows the bibliographic structure of file destination, comprises multiple chapters and sections in bibliographic structure.As it is shown in figure 5, the present embodiment can specifically include step S401～step S403.
Step S401: select the operation of target chapters and sections in response to user in multiple chapters and sections of bibliographic structure, it is determined that the target chapters and sections mark that target chapters and sections are corresponding.
Wherein, user in multiple chapters and sections of bibliographic structure, can select certain chapters and sections.For the ease of describing, it is possible to the chapters and sections that user selects are called target chapters and sections.The selection operation of user can be click, the clicking operation such as double-click.
Client it needs to be determined that target chapters and sections corresponding chapters and sections mark, namely target chapters and sections mark.A kind of concrete form of target chapters and sections mark is, the page number of the first file page that target chapters and sections comprise.File page needs transformed picture to be saved in default picture library, picture has the picture number of self, therefore, the another kind of concrete form of target chapters and sections mark is, the picture number of the picture after the first file page conversion that target chapters and sections comprise, it is necessary to explanation, the picture number of the picture after the first file page conversion that target chapters and sections comprise, can also be called, the picture number of the first pictures of target chapters and sections.
Furthermore, another concrete form of target chapters and sections mark is, the title of chapters and sections, and certainly, the title going back chapters and sections needs have uniqueness in the bibliographic structure of file destination.The title of chapters and sections can be shown to the section name of user in bibliographic structure, it is also possible to is the backstage title arranged for chapters and sections in advance.
Step S402: target chapters and sections mark is included in chapters and sections browse request and sends to server.
Wherein, target chapters and sections mark is encapsulated in chapters and sections browse request by client, and sends chapters and sections browse request to server.Certainly, chapters and sections browse request also needs to comprise the mark of file destination, so that server is when preserving multiple file, accurately search the picture of certain file destination of client request.
Step S403: if receiving the Target Photo that server returns, the first pictures in display Target Photo；Wherein, Target Photo is the picture that server arrives according to target chapters and sections identifier lookup.
Wherein, picture, after the picture of the target chapters and sections mark correspondence of file destination, is returned client by whois lookup.For the ease of describing, the picture found is called Target Photo.It should be noted that, Target Photo can comprise the picture after target chapters and sections identify all files page conversion that the chapters and sections represented comprise, it can also be the picture after the first file page that the chapters and sections that target chapters and sections mark represents comprise converts, or, it is also possible to it is the picture after the first file page that the chapters and sections that target chapters and sections mark represents comprise turns and the picture of the predetermined number after this picture.
No matter Target Photo is which kind of form above-mentioned, after client receives, first show the first pictures in Target Photo, the picture after the first file page conversion that the chapters and sections that namely target chapters and sections mark represents comprise.
It can be seen that the specific implementation of this step may is that the operation selecting target chapters and sections in response to user in multiple chapters and sections of bibliographic structure from the explanation of above about step S401, the picture number of the first pictures of target chapters and sections is defined as target chapters and sections mark.
The process that implements of this implementation may comprise steps of B1.
Step B1: select the operation of target chapters and sections in response to user in multiple chapters and sections of bibliographic structure, obtain the page number of the first file page of target chapters and sections, the page number and target difference are added and after, it is thus achieved that Target Photo is numbered, and Target Photo numbering is defined as target chapters and sections identifies；Wherein, target difference is the difference between the page number of file page and the picture number of picture being converted into.
It is understandable that, the file page of file self has the page number, when file page is converted into picture, usually, strip of paper used for sealing etc. is arranged on the content before file page also can be converted into picture, so, the picture number of picture, just will not be identical between picture number and the page number of file page, but there is difference, difference is the numbering that strip of paper used for sealing etc. is arranged on occupied by the content before file page.
Such as, the page number of certain file page is 10, and strip of paper used for sealing and the summary of this document can be converted into 2 pictures, then the picture number of the picture after the conversion of this document page is 12.
Therefore, client is by after the summation of the page of the first file page of target chapters and sections and difference, it is thus achieved that this document page convert after the picture number of picture, and this picture number be encapsulated in chapters and sections browse request send to server.
