Embodiment

Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.

Embodiment one

With reference to Fig. 1, it illustrates the schematic flow sheet of the method that a kind of browser information of the present invention is shared.Specifically can comprise:

Step 110, after browser current inner triggers download link, obtains failed download list;

In embodiments of the present invention, a failed download list can be built, this failed download list is after a kernel of double-core or multi-core browser triggers download link, download link is switched to the download component of other kernels from current inner, or when downloading from the download component that current inner is switched to independent of browser, if failed download, then for this link, the situation of its handoff failure can be recorded in described failed download list.

Certainly, failed download list of the present invention can maintain cloud server, is upgraded the failed download list of described cloud server by the record of the handoff failure of magnanimity client browser.Each client browser regularly can obtain failed download list update to this locality from described cloud server in use.

So in embodiments of the present invention, for the download link that browser current inner triggers, then first obtain described failed download list, enter step 120.

Step 120, according to described failed download list, selects to determine whether the download component switching another kernel or the download component be switched to independent of browser, performs downloading process according to described download link;

For the failed download list got, the embodiment of the present invention, then by described download link, carries out the matching analysis with the situation of the handoff failure for each download link recorded in failed download list.

If judge the download link triggered for current inner, do not adopt the download component of current inner, and be switched to other download component go perform downloading process will failure time, then adopt the download component of current inner to perform downloading process the download link that current inner triggers, be no longer switched in other download component and perform downloading process.In embodiments of the present invention, then can judge for described download link, be switched to after other download component A failed download number of times a certain reach unsuccessfully threshold value, then determine no longer to be switched to download component A to perform downloading process according to described download link.Other situations by that analogy.

If for the download link that current inner triggers in described failed download list, there is no the record of failed handoff scenario, then continue to be switched in other download component relative with current inner download component and perform downloading process.

Step 130, after the download component after employing one switches performs downloading process failure according to described download link, by the state updating of failed download in described failed download list.

For the download link that current inner is triggered, after being switched to other download component, if judge that other download component perform downloading process failure by described download link, such as cannot be linked to server, download the structure of the expression failed downloads such as time-out, then can switch the failed download state updating of download component in aforementioned failed download list.

The state of described failed download comprises: the download component identity after download link, the kernel triggering download link, switching.Such as download link is www.aaa.com/abnx.ij/101020/3.mp3, and the kernel triggering download link is ie kernel, and the download component identity after switching is the download component of Chrome kernel.So in failed download list, then with above-mentioned download link for keyword, the failed download state after its switching can be upgraded, such as follows at the table one before time failed download:

Table one

Upgrade namely to the failed download number of times+1 being switched to the download component of Chrome kernel of www.aaa.com/abnx.ij/101020/3.mp3 after so aforementioned failure, so in table one, corresponding " 3 " are revised as " 4 ".

Preferably, preferably, described after the download component after employing one switches performs downloading process failure according to described download link, the state updating of failed download is comprised to described failed download list:

Sub-step 131, with the download link of current inner for critical field, the number of times of failed download after record is switched to another download component in described failed download list.

In embodiments of the present invention, if just switch the download link of ie kernel, so failed download list can be optimized for table two:

Table two

Trigger because all download link are ie kernel, so the first hurdle directly can enter statistics using network address as keyword, after this network address, can record the failed download number of times switching to other download component.Such as www.aaa.com/abnx.ij/101020/3.mp3, the download component failed download number of times switching to Chrome kernel is 3, and the failed download number of times switching to sudden peal of thunder download component is 4, if also have the frequency of failure of other download component, then can carry out record later successively.For www.bbb.com/aaaa/101, the download component failed download number of times switching to Chrome kernel is 0, the failed download number of times switching to sudden peal of thunder download component is 5, if also have the frequency of failure of other download component, then can carry out record later successively.

So, circulation like this, the download link of certain kernel of record handoff failure that can be intelligent, again follow-up encounter same download link after, if judge that the download component frequency of failure after the switching of the corresponding record in described failed download list reaches threshold value, be not then switched to corresponding download component and perform downloading process.

Certainly, in embodiments of the present invention, the failed download situation of each browser client record can be uploaded to cloud server, by the unified failed download list upgrading it and safeguard of cloud server, namely as table one or table two, the failed download situation of same download link is carried out adding up and upgrading.

According to the embodiment of the present invention, can record in the failed download list of browser by the download link of a browser kernel be switched to another download component perform downloading process time failure situation, so after certain follow-up kernel triggers download link, determine whether current download link to be switched to the download component of another kernel according to failed download list or perform downloading process independent of in the download component of browser, be switched to the download component of other kernels by current inner for what record in failed download list or be switched to independent of the failed situation of the download component execution of browser, can select not switch, solve thus to a certain be linked at switch kernel download time, download the problem that meeting is always failed, achieve after kernel triggers download link, switching action for possibility failed download will not perform, avoid switching download component and cause failed download, and the beneficial effect that can intelligent revise switching state.

Embodiment two

With reference to Fig. 2, it illustrates the schematic flow sheet of the method that a kind of browser information of the present invention is shared, specifically can comprise:

Step 210, after browser current inner triggers download link, obtains failed download list;

In embodiments of the present invention, failed download list corresponding to download link triggered for ie kernel is as table three:

Table three

In embodiments of the present invention, in failed download list with download link place Main Domain for key word switch after failed download situation record.

Step 220, extracts the Main Domain of described download link, is mated by described Main Domain with the Main Domain in failed download list; If the Main Domain in described Main Domain and failed download list does not match, then enter step 221, if the Main Domain in described Main Domain and failed download list matches, then enter step 222;

In embodiments of the present invention, as shown in Table 3, if the download link of the ie kernel triggering that browser is current is " www.aaa.com/abnx.ij/101020/3.mp3 ", so extract the Main Domain " www.aaa.com " in described download link, described Main Domain is mated with the Main Domain in table three; Discovery matches, then enter step 222.

Certainly, if the Main Domain in described Main Domain and failed download list does not match, then step 221 is entered.

Step 221, the download component switching another kernel or the download component be switched to independent of browser, to perform downloading process according to described download link; Enter step 230;

Namely the download link triggered for current inner is described, the download component that it is switched to another kernel without any record declaration or in being switched to independent of browser download component, perform the situation that downloading process can be failed, therefore can adopt the download component of another kernel or be switched in the download component independent of browser, first performing downloading process.

Whether step 222, exist Unrecorded download component under judging Main Domain described in described failed download list; If there is Unrecorded download component, then enter step 223; If there is no Unrecorded download component, then enter step 224;

As in table three, the download component of certain kernel after the switching of crossing for not having failed download, the kernel component of its correspondence of kernel may can not be recorded in table three by it, such as download component C and download component D, only have recorded in table three and switch Chrome failed download number of times and switch sudden peal of thunder download time, do not record download component C completely, the frequency of failure of download component D, and in multiple kernels of browser, also have the kernel supporting download component C and download component D, browser can also call the download component C independent of browser and the download component D independent of browser in other words, the download component D supporting download component C and can call independent of browser is also had in other words in the multiple kernel of browser.So for this kind of situation, step 223 can be entered.

If the kernel of current browser or all records in described download list of the download component independent of browser that can call, then enter step 224.

Step 223, is switched in described Unrecorded download component one to perform downloading process according to described download link; Enter step 230;

In previous example, one can be selected in download component C or download component D, described download link is switched in download component C or download component D, to perform downloading process.

Step 224, judges whether to exist the download component that failed download number of times is less than unsuccessfully threshold value; If there is the download component that failed download number of times is less than unsuccessfully threshold value, enter step 225; If there is no failed download number of times is less than unsuccessfully the download component of threshold value, enters step 226;

The download component of each switchable kernel of all browsers is have recorded in such as download list, and the download component independent of browser that browser can call, whether the frequency of failure after switching under so can judging each kernel is less than unsuccessfully threshold value, in such as table three, if threshold value is failed threshold value is 5, so switch that Chrome failed download number of times is 3, to switch sudden peal of thunder failed download number of times be 3, be less than unsuccessfully threshold value 5, so can enter step 225.

And when the failed download number of times of all records is all greater than unsuccessfully threshold value, then enter step 226.

Step 225, is switched to one that the described frequency of failure is less than unsuccessfully in the download component of threshold value, to perform downloading process according to described download link; Enter step 230;

So, the download component described download link being switched to chrome kernel can be selected, or be switched to sudden peal of thunder download component, perform downloading process.

Step 226, is not switched to another download component, adopts the download component of current inner to perform downloading process to perform downloading process according to described download link;

The download link that current ie kernel is no longer set out is switched in other download component, and adopts the download component of ie kernel itself to perform downloading process according to described download link.

Step 230, after the download component after employing one switches performs downloading process failure according to described download link, extracts the Main Domain of the download link of described current inner;

Step 231, searches in described failed download list whether have this Main Domain; If have described Main Domain in described failed download list, then enter step 232; If there is no described Main Domain in described failed download list, then enter step 235;

Whether step 232, have the described download component field after switching under judging described Main Domain; If there is the described download component field after switching under described Main Domain, then enter step 233; If do not remember the described download component field after having switching under described Main Domain, then enter step 234;

Step 233, the frequency of failure under this download field adds 1;

Step 234, adds described download component field, and records handoff failure number of times under described download component field;

Step 235, adds described Main Domain, and under described Main Domain, add the download component field after described switching, to record handoff failure number of times under described download component field.

Step 230 is to 235 for convenience of description, is described below with several example:

(1), when ie kernel triggers the download link of www.aaa.com/193939/sjsj, and the download component switching to chrome kernel performs downloading process, and after this downloading process failure.First extract in step 230 the Main Domain " www.aaa.com " of download link, in the download list then in step 231 in look-up table three, whether have this Main Domain; Find that there is, after this Main Domain, then search the download component field whether having chrome kernel, find that there is " switching Chrome failed download number of times ", then enter step 233, by the number of times+1 of corresponding " www.aaa.com " under described " switching Chrome failed download number of times ", obtain 4.Obtain the table after upgrading, as table four:

Table four

(2), when ie kernel triggers the download link of www.aaa.com/193939/kkkk, and download component C execution downloading process is switched to, and after this downloading process failure.First extract in step 230 the Main Domain " www.aaa.com " of download link, in the download list then in step 231 in look-up table three, whether have this Main Domain; Find that there is, then after this Main Domain, search whether there is download component C field, find do not have, then enter step 234, add field " switch download component C the frequency of failure ", and described " switching the download component C frequency of failure " " under record handoff failure number of times 1.Obtain the table after upgrading, as table five:

Table five

(3), when ie kernel triggers the download link of www.ccc.com/19lll9/sjsj, and the download component switching to chrome kernel performs downloading process, and after this downloading process failure.First extract in step 230 the Main Domain " www.ccc.com " of download link, in the download list then in step 231 in look-up table three, whether have this Main Domain; Discovery does not have, then step 235, adds described Main Domain, and under described Main Domain, add the download component field after described switching, to record handoff failure number of times under described download component field.Obtain the table after upgrading, as table six:

Table six

Certainly, in embodiments of the present invention, each browser client be by new switching after the state of failed download of download component upload onto the server, then upgrade down loading updating list by server is unified.

According to the embodiment of the present invention, can record in the failed download list of browser by the download link of a browser kernel be switched to another download component perform downloading process time failure situation, so after certain follow-up kernel triggers download link, determine whether current download link to be switched to the download component of another kernel according to failed download list or perform downloading process independent of in the download component of browser, be switched to the download component of other kernels by current inner for what record in failed download list or be switched to independent of the failed situation of the download component execution of browser, can select not switch, solve thus to a certain be linked at switch kernel download time, download the problem that meeting is always failed, achieve after kernel triggers download link, switching action for possibility failed download will not perform, avoid switching download component and cause failed download, and the beneficial effect that can intelligent revise switching state, in addition, failed download list of the present invention can be expanded for the browser of various structure very easily.

Embodiment three

With reference to Fig. 3, it illustrates the schematic flow sheet of the method that a kind of browser information of the present invention is shared, specifically can comprise:

Step 310, judges whether the link that browser current inner triggers is download link.

In the embodiment of the present invention, for the link that browser triggers, first need to judge whether it is download link.

Sub-step 311, the value of the file type field in responding for the HTPP that the HTTP request that current inner sends is fed back according to server, when the value of described file type field be browser kernel can not resolve to the type of showing in the page time, then what judge described correspondence is linked as download link.

When the kernel of browser sends network request, generally first build HTTP request for URL and be sent to server, and server can respond and return to browser kernel by the file generated corresponding according to this URL accordingly, the format sample of this response is roughly:

HTTP/1.0200OK

Date:Mon,31Dec201304:25:57GMT

Server:Apache/1.3.14(Unix)

Content-type:text/html

Last-modified:Tue,17Apr201206:46:28GMT

Content-length:39725426

Content-range:bytes554554-40279979/40279980

Wherein, the first row is protocol name HTTP and version number 1.0, has a three-figure numeral after space, and be the responsive state code of http protocol, 200 represent successfully, and OK is the brief textual description to status code.Status code has 5 classes: 1xx belongs to notice class; 2xx belongs to successfully class; 3xx belongs to redirected class; 4xx belongs to client error class; 5xx belongs to service end mistake class.Content-Length identification data length.Second row Date represents the current GMT time.The third line Server represents server name.Fourth line Content-type represents the file type of client-requested data.Fifth line represents the last modification time of Last-modified server data.6th row Content-length represents content-length.7th row Content-range represents data area.

In the embodiment of the present invention, the data render of correspondence can become webpage to show by the kernel of browser for the data of current correspondence by Content-type field instruction browser, or webpage can not be become to carry out showing the data render of correspondence by the kernel of browser and need to call download component and download.Namely can judge whether the network request of the correspondence that browser sends is download request according to the value of Content-type field, such as Doctype is that text/html represents html document, can be become that the form of webpage is shown, Doctype is that the non-picture of image/jpeg also can become the form of webpage to show by the render engine renders of browser kernel by the render engine renders of browser kernel.And Doctype to be application/octet-stream be expressed as binary stream, cannot be played up by browser kernel and show etc. in webpage, need to download.

Therefore, when judging the value of the file type field in the response that described server feeds back for the HTTP request that browser kernel sends, when the value of described file type field be browser kernel can not resolve to the type of showing in the page time, then judge described HTTP request corresponding be linked as download link.
