Fig. 3 is the process flow diagram of the update method of a kind of e-book according to an exemplary embodiment.Perform for terminal and server the method that disclosure embodiment provides alternately, as shown in Figure 3, the method that disclosure embodiment provides comprises the following steps.

In step S301, terminal to server sends e-book update request, and wherein, e-book update request carries the mark of e-book.

Particularly, when terminal needs to upgrade the e-book that it stores, trigger by sending e-book update request to server.In order to make the clear and definite terminal of server need to upgrade which e-book, in e-book update request, carry the mark of e-book.Wherein, e-book identifies for distinguishing different e-books, the mark of the e-book that e-book correspondence overall situation is unique.

Send the trigger condition of e-book update request about terminal to server, can have a variety of.Such as, after server determines that this e-book upgrades, the notification message of e-book renewal can be sent to terminal.After terminal receives this notification message, send e-book update request to server.Or terminal, according to the operation of user, sends e-book update request to server.Wherein, terminal can provide e-book more new option.On this basis, when user upgrades e-book, can by choose this e-book more new option realize.Particularly, user choose e-book more new option time, can by click, double-click or long by this e-book more new option realize.

In addition, whether terminal can also there occurs renewal by periodic test e-book, and when determining that e-book occurs to upgrade, sends e-book update request.Wherein, terminal, can by periodically realizing to the renewal apply for information of server transmission e-book when whether periodic test e-book occurs to upgrade.The mark of e-book is carried, so that server determination terminal needs to inquire about which e-book whether there occurs renewal in this renewal apply for information.About the cycle that terminal checks, can be 3 days, 5 days etc., disclosure embodiment do concrete restriction to this.

In step s 302, after the e-book update request that server receiving terminal sends, according to the mark of e-book, the first framework file of the local e-book stored is returned to terminal, wherein, first framework file comprises the frag info of each fragment of e-book of server stores, and frag info at least comprises fragment identification.

In the disclosed embodiments, upgrade e-book for the ease of terminal, e-book can be divided into multiple fragment by server in advance, and generates the framework file of this e-book, and this framework file comprises the frag info of each fragment of e-book.On this basis, when terminal needs to upgrade e-book, upgrade needing the fragment upgraded according to framework file.Wherein, server, when generating the framework file of e-book, includes but not limited to be realized to step 4 by following step one:

Step one: e-book is divided into multiple fragment by server.

Wherein, e-book, when splitting e-book, can be divided into multiple fragment according to the catalogue of e-book by server.Now, chapters and sections of e-book can a corresponding fragment.In addition, the often appointment numerical value page of e-book according to the number of pages of e-book, can also be divided into a fragment by server.Such as, a fragment is divided into by every 50 pages, 100 pages of e-book.

Step 2: server is each fragment allocation fragment identification.

For the ease of distinguishing each fragment, server is the unique fragment identification of each fragment allocation overall situation, to be different from the fragment identification of other fragment.

Step 3: according to the content of each fragment, generates the fragment cryptographic hash of each fragment.

Wherein, e-book, when upgrading, may occur that the partial content of a certain fragment has carried out more news.Such as, upgrade because content is before wrong in some chapters and sections.In order to make terminal when upgrading e-book, determine whether because the content of some fragments changes and upgrade this fragment, server according to the content of each fragment, can generate the fragment cryptographic hash of each fragment.Wherein, server, when generating the fragment cryptographic hash of each fragment, can realize by specifying cryptographic algorithm according to the content of each fragment.This appointment cryptographic algorithm includes but not limited to as MD5 (Message-Digest Algorithm 5, message digest algorithm 5).

Particularly, after for each fragment allocation fragment identification, terminal can determine whether there is non-existent fragment relative to the e-book of server stores in the local e-book stored according to fragment identification, or whether has the deleted fragment of server.When after the fragment cryptographic hash generating each fragment, according to fragment cryptographic hash, terminal can determine whether the content of a certain fragment upgrades.

In the disclosed embodiments, the frag info of each fragment at least comprises the fragment identification of each fragment and the fragment cryptographic hash of each fragment.Certainly, the frag info of fragment can also have other content, and disclosure embodiment does not limit the particular content of frag info.Such as, frag info can also comprise the mode that e-book is divided, and this dividing mode comprises by chapter construction or according to number of pages division etc.

Step 4: according to the frag info of all fragments, generates the first framework file.

In order to identify the frag info of all fragments of e-book, server, according to the frag info of all fragments, generates the first framework file.In the disclosed embodiments, the first framework file refers to the current architecture file of the e-book of server stores.Wherein, after e-book upgrades, server upgrades the framework file that server this locality stores, to obtain the first framework file in real time.Therefore, the first framework file is used in reference to the up-to-date framework file of the e-book of server stores.

As shown in table 1, it is a kind of signal table of the first framework file.

Table 1

Fragment identification	Fragment cryptographic hash
		1st fragment	Cryptographic hash 1

2nd fragment	Cryptographic hash 2
		……	……
N-th fragment	Cryptographic hash n

Certainly, the data in table 1 only for citing, can not form the restriction to disclosure embodiment.

In conjunction with foregoing, in order to make which fragment of clear and definite this e-book of terminal there occurs renewal, this first framework file is back to terminal by server.

In step S303, after first framework file of the e-book that terminal reception server returns, according to the first framework file and the second framework file, determine the fragment identification of the fragment to be updated of the local e-book stored, wherein, the second framework file comprises the frag info of local each fragment of e-book stored.

In the disclosed embodiments, the second framework file refers to the framework file of this e-book that terminal local stores.In order to determine to upgrade which fragment, terminal, according to the first framework file and the second framework file, determines the fragment identification of the fragment to be updated of the local e-book stored, and upgrades the local e-book stored at the follow-up fragment identification according to fragment to be updated.

Wherein, when terminal determines the fragment identification of the fragment to be updated of the local e-book stored, following several situation has been included but not limited to:

The first situation: when the first framework file exists newly-increased fragment identification relative to the second framework file, using the fragment identification of newly-increased fragment identification as fragment to be updated.

Particularly, when some fragment identification are present in the first framework file, and be not present in the second framework file, then illustrate in the e-book of server stores to there is newly-increased fragment.In order to this newly-increased fragment is kept at terminal local, terminal determines that this newly-increased fragment identification is the fragment identification of fragment to be updated.

The second situation: when the first framework file has deleted fragment identification relative to the second framework file existence, will delete the fragment identification of fragment identification as fragment to be updated.

Particularly, when some fragment identification are not present in the first framework file, and be present in the second framework file, then illustrate in the e-book of server stores and deleted fragment corresponding to this fragment identification.Now, terminal can be determined to need to delete this fragment in this locality, and therefore, terminal determines that this has deleted the fragment identification that fragment identification is defined as fragment to be updated.

The third situation: when the first framework file is all identical with all fragment identification in the second framework file, and when in the first framework file, arbitrary fragment cryptographic hash is different from the homologous segment cryptographic hash in the second framework file, using the fragment identification of fragment identification different for fragment cryptographic hash as fragment to be updated, frag info also comprises fragment cryptographic hash.

Particularly, when the first framework file is all identical with all fragment identification in the second framework file, then the not newly-increased fragment of the e-book of server stores is described, does not also delete fragment.But, when fragment cryptographic hash arbitrary in the first framework file is different from the homologous segment cryptographic hash in the second framework file, then illustrate that the content of this fragment there occurs renewal, therefore, terminal is using the fragment identification of fragment identification different for this fragment cryptographic hash as fragment to be updated.

Such as, if the fragment identification of Segment A is identical with the fragment identification of Segment A in the first framework file in the second framework file, and the fragment cryptographic hash of Segment A is " 222345 " in the first framework file, in second framework file, the fragment cryptographic hash of Segment A is " 222346 ", then the server update content of Segment A is described.Now, terminal is using the fragment identification of Segment A as fragment to be updated.

In step s 304, terminal, according to the fragment identification of fragment to be updated, upgrades the e-book that this locality stores.

After terminal determines the fragment identification of fragment to be updated, then specify which fragment needs to upgrade, therefore, terminal, according to the fragment identification of fragment to be updated, upgrades the e-book that this locality stores.

Particularly, in conjunction with the above-mentioned content determining the fragment identification of fragment to be updated, terminal, according to the fragment identification of fragment to be updated, when upgrading the e-book of this locality storage, has included but not limited to following several situation:

The first situation: when the fragment identification of fragment to be updated is the different fragment identification of newly-increased fragment identification or cryptographic hash, terminal needs to carry out newly-increased fragment by the fragment identification downloading fragment to be updated or upgrade the content of some fragment.In that case, when terminal upgrades the segment contents of these fragments, can be realized by step S3041 to step S3044:

In step S3041, terminal to server sends content update request, and wherein, the fragment identification of fragment to be updated is carried in content update request.

Particularly, need for the ease of server determination terminal which fragment upgrading e-book, the fragment identification of fragment to be updated is carried in the content update request that terminal to server sends.Disclosure embodiment does not limit the mode that terminal to server sends content update request.

In step S3042, after server receives this content update request, obtain the chained address of the fragment identification corresponding content of fragment to be updated, and return to the chained address of the fragment identification corresponding content of fragment to be updated to terminal.

Determine the content which chained address to download fragment to be updated to enable terminal, server obtains the chained address of the fragment identification corresponding content of fragment to be updated, and returns to the chained address of the fragment identification corresponding content of fragment to be updated to terminal.Now, terminal can be downloaded from this chained address and obtain content corresponding to the fragment identification of fragment to be updated.

Certainly, server also can return the content of fragment corresponding to fragment identification to be updated directly to terminal, but, because the content of certain fragment may be many, the segment contents directly returning fragment to be updated may be more consuming time, therefore, in the disclosed embodiments, server upgrades content corresponding to the fragment identification of fragment to be updated, to save the e-book update time of terminal preferably by carrying out triggering terminal to terminal back link address.

In step S3043, behind the chained address that terminal reception server returns, download content corresponding to the fragment identification of fragment to be updated according to chained address.

Wherein, disclosure embodiment does not limit the mode that terminal downloads content corresponding to the fragment identification of fragment to be updated according to chained address.During concrete enforcement, terminal in the click of detection user on this chained address, double-click or long by when operating, can trigger the content that the fragment identification of download fragment to be updated is corresponding.

The second situation: when the fragment identification of fragment to be updated is for deleting fragment identification, terminal can obtain in the local e-book stored and delete content corresponding to fragment identification, and delete in the e-book that terminal local stores and deleted content corresponding to fragment identification, thus to be consistent with the content of the e-book of server side.

Such as, when fragment B is for deleting fragment identification, terminal, from the e-book that this locality stores, obtains the content of fragment B, and deletes the content of fragment B.

In step S305, terminal, according to the fragment identification of fragment to be updated, upgrades the second framework file.

Particularly, after upgrading the local e-book stored, terminal according to the fragment identification of fragment to be updated, can also upgrade the second framework file.When follow-up renewal e-book, can realize according to the second framework file after renewal.

Wherein, this newly-increased fragment identification, when renewal second framework file, for newly-increased fragment identification, is added in local the second framework file stored by terminal; For deleting fragment identification, deleting this in the first framework file that terminal stores in terminal local and deleting fragment identification; For the fragment identification that cryptographic hash is different, then the fragment cryptographic hash that the fragment identification that local this cryptographic hash stored of change is different is corresponding.

The method that disclosure embodiment provides, first framework file of the e-book that terminal returns at reception server, and after determining the fragment identification of fragment to be updated according to the second framework file that the first framework file and terminal local store, fragment identification according to fragment to be updated upgrades the e-book that terminal local stores, when making the e-book when server side occur to upgrade, the fragment that terminal only needs update content to change, and without the need to upgrading whole e-book, improve renewal speed and efficiency.In addition, when renewal e-book needs the content again downloading fragment to be updated, and the content downloading these fragments is when needing data traffic, by upgrading the flow waste that individual segments can be avoided causing because upgrading whole e-book, thus data traffic can be saved.
