S202: target web is conducted interviews according to web access requests, and to content distributing network CDN(ContentDelivery Network) acquisition request needs the first web page resources of being carried in target web;

S204: judge whether successfully to obtain the first web page resources, wherein,

If not, step S206 is performed;

S206: obtain second web page resources consistent with the content of the first web page resources from the backup network beyond CDN.

According to the web page resources acquisition methods that the embodiment of the present invention provides, in step s 102, can conduct interviews to target web according to web access requests, and need the first web page resources of being carried in described target web to CDN acquisition request.

Generally speaking, in embodiments of the present invention, the above-mentioned web access requests to target web can come from the identification clicked of the link to the sensing target web in browser or user interface usually, and, as the one of Internet resources, the web page files of above-mentioned target web usually can pass through uniform resource position mark URL (Uniform ResourceLocator) and position, such as, in some embodiments of the invention, namely web access requests can be formed with identification to the seizure of the mouse click action existed in above-mentioned browser or user interface on the passage of URL hyperlink.Certainly, the link of above-mentioned sensing target web also can not appear on word, but on element in other browsers such as icon, picture, video pictures or user interface, the present invention is not construed as limiting this.

It should be noted that, a kind of comparatively common form of expression of the just web access requests described in above-described embodiment, and nonessential execution mode, such as, in some embodiments of the invention, the generation of web access requests also can have nothing to do with the input signal read from computer entry device, such as, this web access requests can be generated automatically by the application run in client, to be formed the ejection page on browser or user interface, as the access of navigation page etc., the present invention is not limited in any way this.

Based on the above-mentioned access request to target web, the access to target web can be realized, but due to form restriction, the web document corresponding with target web self is typically not enough to the full detail content containing and present needed for it.

Generally speaking, target web can show as HTML html(Hypertext MarkupLanguage usually) web document of form, and can by carrying out the different elements edited in this web document, the concrete presentation mode of the objective definition webpages such as such as text, image, audio frequency, video, interactive form, thus dissimilar information can be shown in webpage, and realize and external information mutual.

Wherein, a part in above-mentioned web page element directly can be recorded in the inside of above-mentioned web document, directly loaded by loader, browser or user interface etc., and the mode that another part can be linked by external resource, utilize the chained address being present in the web page resources of the outside of this web document of recording in web document, realize calling these web page resources, and be further advanced by loader, browser or user interface etc. and be loaded in target web, to form above-mentioned web page element.Wherein, the chained address of above-mentioned web page resources also can show as URL usually, but the present invention is not construed as limiting this.

As previously mentioned, in the prior art, the above-mentioned web page resources being present in the outside of web document can leave that data link between web page access terminal is shorter in, on the node of data transmission bauds CDN faster, wherein, this node may be used for representing a territory in computer network, and computer or a server etc. that also can represent wherein have the storage medium of basic data processing function.Wherein, for ease of following description, the above-mentioned web page resources being used for loading to target web left in CDN node can be designated as the first web page resources.

Particularly, corresponding with above-mentioned web page element, first web page resources also can have polytype, such as text, picture, video file etc., and its file format also can have multiple, such as, comparatively common, Javascript script or CSS CSS(Cascading Style Sheet can be comprised) file etc. of type, the present invention does not all do any restriction to this, is interpreted as the web page resources of feasible arbitrary form.

It should be noted that, in embodiments of the present invention, target web can call this first web page resources according to the URL of the first web page resources recorded in web document corresponding with it, but first web page resources corresponding with this URL might not leave preposition in CDN in, such as, by data dump or the renewal rewards theory of CDN server, this the first web page resources can be deleted from CDN, or be updated to other addresses or path, also be, in some embodiments of the invention, client can to CDN acquisition request first web page resources, but this first web page resources also can not be present in above-mentioned CDN.It should be noted that, above-mentioned scene does not affect the enforcement of technical solution of the present invention, should not be construed as yet and forms any restriction to the present invention.

According to the web page resources acquisition methods that the embodiment of the present invention provides, as shown in Figure 2, in step S204, can, above-mentioned after CDN acquisition request first web page resources, judge whether successfully to obtain described first web page resources.

Generally speaking, the acquisition request of above-mentioned first web page resources can show as is called in other words by the access of URL to the first web page resources corresponding with it, wherein, for ease of describing, the above-mentioned chained address for locating the first web page resources is defined as a URL.

Particularly, under above-mentioned scene, the response that CDN obtains request for above-mentioned web page resources generally can comprise following four kinds of situations:

1) CDN obtains request to web page resources and makes response, and the first web page resources is sent to client;

2) CDN obtains request to web page resources and makes response, and there is first web page resources corresponding with a URL, but unsuccessful first web page resources is sent to client;

3) CDN obtains request to web page resources and makes response, but there is not first web page resources corresponding with a URL;

4) CDN does not obtain request to web page resources and makes response.

Wherein, for the first situation, can judge successfully to obtain described first web page resources, also namely client can normally obtain web page resources from CDN and realize the access to complete target web, the scheme obtaining web page resources from CDN in view of client belongs to technical scheme ripe prior art, and the present invention does not do tired stating at this.

For second case, particularly, in some embodiments of the invention, the network security that can derive from client is arranged, such as fire compartment wall, the restriction etc. of resource access of downloading shielding, arranging in client or the territory residing for it, thus cause CDN after the acquisition request receiving the first web page resources, the first web page resources cannot be sent to browser or user interface etc. in client, thus described first web page resources of unsuccessful acquisition can be judged.

For the third situation, as previously mentioned, in some embodiments of the invention, first web page resources can leave the position beyond a URL in, such as, in the renewal rewards theory of CDN server, the access path of the one URL is changed, Deng, thus cause CDN the first web page resources cannot be sent to client, also can be judged as described first web page resources of unsuccessful acquisition.

For the 4th kind of situation, particularly, in some embodiments of the invention, the access that can derive from the node in the CDN depositing the first web page resources is arranged, such as, user beyond the white list forbidding this Node configuration to the access of this node, thus causes CDN to fail to respond to the acquisition request of the first web page resources, also should be judged as described first web page resources of unsuccessful acquisition.

For above situation, can judge to draw to it judged result whether successfully obtaining described first web page resources respectively, but, on the other hand, the above-mentioned judgement operation whether successfully obtaining described first web page resources also can arrange with user and network environment has nothing to do, the port such as can specified in client is monitored, and to detect after transmission web page resources obtains request, whether success receives the first web page resources from CDN.

Certainly, above embodiment is a kind of example, and in embodiments of the present invention, can also judge whether successfully obtaining the first web page resources by other means, alternatively, as shown in Figure 3, step S204 can comprise:

S302: judge whether successfully the first web page resources to be loaded in target web, wherein,

If so, then step S304 is performed,

If not, then step S306 is performed;

S304: judge successfully to obtain the first web page resources;

S306: judge unsuccessful acquisition first web page resources.

Generally speaking, in the process that target web is conducted interviews, web document corresponding to target web pulls the first web page resources by browser or loader, and after successfully obtaining the first web page resources, be loaded in the target web be presented in browser or user interface, thus, in embodiments of the present invention, the result of the judgement of success or not can be loaded by the first web page resources, judge whether successfully to obtain the first web page resources from CDN, wherein, if the first web page resources needed for target web is successfully loaded in target web, then can judge that client success obtains the first web page resources from CDN before load operation, be loaded in target web if the first web page resources needed for target web is unsuccessful, then no matter loading failed reason comes from the acquisition of the first web page resources in CDN failed, or the loading failure of browser or loader, all can be considered as acquisition first web page resources that fails, thus backup network acquisition request second web page resources can be turned in step S206.

It should be noted that, in some embodiments of the invention, for the load mode of the web page resources based on html label, its loading action synchronously can be carried out with the acquisition request of web page resources, particularly, such as, be the situation of Javascript script file for the first web page resources, can be loaded this Javascript script file by html label as follows:

Wherein, " <script></script > " may be used for representing the <script> label in html label, this label may be used for the file defining script type, wherein

Type attribute may be used for multipurpose internet mail extensions MIME (the MultipurposeInternet Mail EXtensions) type specifying this script file; wherein, " javascript " may be used for representing that the type of this script file is Javascript script file;

Charset attribute may be used for the character code mode specifying this Javascript script file, and such as, above-mentioned " utf-8 " may be used for representing Unicode coded system;

Src attribute may be used for pointing to external script files, also i.e. this Javascript script file, and the access path of this Javascript script file can be specified by the assignment of Src attribute, wherein, this access path is usually expressed as the URL of this Javascript script file, " script.js " as escribed above.

As can be seen from the above description, in the process Javascript script file as the first web page resources loaded by above-mentioned html<script> label, owing to being defined the access path of this Javascript script file by Src attribute, and can conduct interviews to it according to this path and call, thus the request the first web page resources being proposed to acquisition while loading can be considered as.

It should be noted that, for the load mode of the web page resources based on static html label, because it is difficult to the stress state accurately judging script, thus in some embodiments of the invention, JS (Javascript) loader can be used to load Javascript script file, under above-mentioned scene, as shown in Figure 4, alternatively, step S302 can comprise:

S402: judge whether successfully described Javascript script file to be loaded in described target web by loader.

Wherein, common JS loader has a lot, such as, it can be the loader based on script DOM mode, also can be the loader based on ajax eval mode, and other feasible loaders that may be used for judging whether Javascript script file successfully loads, the present invention is not construed as limiting this.

Similarly, be the situation of CSS file, can be loaded equally by html label to it for the first web page resources, such as, this html label can be:

Wherein, " <link> " may be used for representing the <link> label in html label, this label may be used for defining the relation between web document and the web page resources of outside, and usually may be used for link shape table, such as CSS file, wherein

Type attribute may be used for the mime type specifying this external web page resource, and wherein, " text/css " may be used for representing that this web page resources be linked is CSS file;

Rel attribute may be used for specifying the linking relationship between above-mentioned web document and this CSS file, and wherein, " stylesheet " may be used for representing link shape table;

This CSS file that Media attribute may be used for specifying to be linked shows on the equipment of what type, and such as, above-mentioned " screen " may be used for representing and show on PC equipment;

Charset attribute may be used for the character code mode specifying this CSS file, and such as, above-mentioned " utf-8 " may be used for representing Unicode coded system;

Href attribute may be used for the access path defining this CSS script file, and wherein, this access path is usually expressed as the URL of this CSS file, "/css/master.css " as escribed above.

Similarly, in the process CSS file as the first web page resources loaded by above-mentioned html<link> label, owing to being defined the access path of this CSS file by Href attribute, and can conduct interviews to it according to this path and call, thus the request the first web page resources being proposed to acquisition while loading can be considered as.

As shown in Figure 5, in embodiments of the present invention, be the situation of CSS file for the first web page resources, step S302 can comprise:

S502: in the predetermined time period after need the first web page resources loaded in CDN acquisition request target web, judge whether the document dbject model DOM node of specifying in target web is successfully carried in the preset style corresponding with DOM node recorded in CSS file

If so, then step S504 is performed,

If not, then step S506 is performed;

S504: judge successfully to load CSS file in target web;

S506: judge unsuccessful loading CSS file in target web.

Wherein, DOM is as a kind of standard programming interface, with reference to its regulation, in embodiments of the present invention, each composition in web document all can be considered as a DOM node, such as, this DOM node can be the entirety of web document, can, for the above-mentioned html label for linking external web page resource, can also be also the web page element recorded in web document, such as text wherein or html attribute, etc.

In embodiments of the present invention, the pattern can specified for one or more DOM Node configuration in CSS file, as above-mentioned the preset style, and the designator successfully loading this CSS file is judged whether with this preset style, after trial loads this CSS file, whether successfully act in target web according to designator, judge whether CSS file loads successfully.Particularly, such as, as wherein a kind of optional execution mode, can be arranged DOM node by the statement of the following form in CSS file:

object{visibility:hidden}，

Wherein, whether visibility attribute may be used for regulation object element visible, wherein, " hidden " may be used for representing that this element is invisible, such as, for the situation that object is " head ", can be invisible by the style setting of title, thus can request this CSS file is loaded after predetermined time period in, judge whether this CSS file successfully loads by the detection of the pattern to this title, wherein, if this title is invisible, then can judge that CSS file successfully loads, if this title is visible, then can judge the unsuccessful loading of CSS file.

It should be noted that, in embodiments of the present invention, to the first web page resources, the loading that such as above-mentioned Javascript script file or CSS file carry out, should be understood to the request loaded, wherein, above-mentioned Javascript script file or CSS file can not be stored in CDN, also can unsuccessfully be obtained or obtain rear to be unsuccessfully loaded in target web by client, thus can be considered as asking unsuccessfully.For above-mentioned scene, should not be construed as to define with the description of technical solution of the present invention and conflict.

In addition; it should be noted that; in the above-described embodiments; action for the loading of the first web page resources synchronously can be carried out with the action obtained; but this does not affect the enforcement of the web page resources acquisition methods according to the embodiment of the present invention; should not be construed as to define with technical solution of the present invention and conflict, also should not be construed as and restriction is constituted to the present invention, and must be considered as within protection scope of the present invention.

According to the web page resources acquisition methods that the embodiment of the present invention provides, in step S206, according to the judged result of step S204, when unsuccessful acquisition the first web page resources, second web page resources consistent with the content of the first web page resources can be obtained from the backup network beyond described CDN.

In embodiments of the present invention, outside first web page resources that can store in CDN, the second web page resources is deposited in backup network, wherein, the content of the second web page resources can be consistent with the first web page resources, such as, in other embodiments of the present invention, second web page resources can leave in backup network as the backup of the first web page resources, but the present invention is not construed as limiting this.

The situation of the first web page resources cannot be obtained from CDN for above-mentioned client, unsuccessful acquisition first web page resources can be judged, thus can in step S206, the second web page resources is obtained from the backup network beyond CDN, wherein, second web page resources can leave in above-mentioned backup network as the backup of the first web page resources in advance, calling in order to target web, thus the optional implementation environment of one of the web page resources acquisition methods according to the embodiment of the present invention can be formed, as shown in Figure 6.

Be similar to the first web page resources, the file format of the second web page resources, the information type comprised and concrete manifestation form thereof also can have multiple choices, generally speaking, can be identical with the first web page resources, so that target web is when obtaining the first web page resources from CDN, can obtains by intimate consistent web page resources acquisition request and web page resources load mode and load the second web page resources.But this and do not mean that the present invention has made restriction to this, such as, in some embodiments of the invention, second web page resources also can show as to the first web page resources be optimized process after leave web page resources in backup network in, such as, through the web page resources of overcompression process or form optimization process, thus be convenient to the storage and management of web page resources in backup network.Certainly, be more than a kind of example, the present invention is not limited in any way this.

On the other hand, as the storage medium of the second web page resources, backup network also can have multiple implementation, it can be embodied in a memory device in the network beyond CDN, also can show as the combination of multiple devices, equipment combines the computer territory that formed or a computer network widely, the present invention is not limited in any way this.

In embodiments of the present invention, the concept of backup network can be corresponding with the second web page resources be pre-stored in wherein, such as, the computer network having the second web page resources can be considered as above-mentioned backup network.Certainly, on the other hand, backup network also can be specified in advance, for depositing multiple second web page resources of the backup as the web page resources needed for target web, wherein, alternatively, backup network can be appointed as the network area at target web place, thus under the prerequisite that can conduct interviews to target web, namely can obtain the second relevant web page resources in consolidated network region, and then reach the technique effect of the reliability improving web page access.

Especially, in some embodiments of the invention, backup network can also refer to be decided to be other CDN outside the above-mentioned CDN depositing the first web page resources, wherein, namely the backup of the first web page resources deposited in other CDN above-mentioned can be considered as the second web page resources, thus when the first web page resources cannot successfully obtain, can from the acquisition of above-mentioned other CDN realization to the second web page resources, wherein, other CDN above-mentioned also can be chosen to be the combination of the CDN node comparatively close with the client in specified network region, thus can under the prerequisite of reliability improving web page access, further reduction obtains the impact of the webpage access speed decline caused because the first web page resources fails.

In addition, should be understood that, technical solution of the present invention can also be combined with each other with other the feasible technological means known to those skilled in the art, to obtain more excellent technique effect, such as, for the orientation of other CDN above-mentioned, also can pass through domain name system DNS (Domain Name System) and realize.It should be noted that, similar to technical solution of the present invention distortion, expand and and the technical scheme that formed of the combination of other common technology means and execution mode all should be considered as within the scope of protection of the invention.

As shown in Figure 6, under above-mentioned scene, when client is difficult to obtain the first web page resources from CDN, can by obtaining second web page resources consistent with the content of the first web page resources from backup network, solve in prior art when client be difficult to cause when obtaining web page resources from CDN be difficult to load the web page element corresponding with this web page resources target web thus being difficult to of causing carries out normal technical problem of accessing to target web, realize technique effect target web being carried out to normal access, and improve the reliability of web page access.

It should be noted that, in embodiments of the present invention, the first above-mentioned web page resources should be considered as obtaining with the web page resources sent to CDN asking corresponding concept, also be, the web page resources to CDN acquisition request that it is benchmark that first web page resources is interpreted as with the web page element loaded needed for target web, therefore, web page resources in CDN carry out upgrading or other types data processing after the change for the first web page resources that occurs, such as, when the first web page resources is deleted, still consistent second web page resources corresponding to the content of the first deleted web page resources preserved in backup network, still be interpreted as the second web page resources met described by technical solution of the present invention, do not affect implementation condition of the present invention, also should not be construed as and restriction is constituted to the present invention.

Alternatively, as a kind of concrete execution mode, as shown in Figure 7, in step S206, above-mentioned backup network beyond CDN obtains second web page resources consistent with the content of the first web page resources and can comprise:

S702: the URL being used for locating the first web page resources is updated to the 2nd URL, wherein, the 2nd URL is for locating the second web page resources be pre-stored in backup network;

S704: obtain the second web page resources by the 2nd URL.

By above embodiment, provide a kind of second web page resources is carried out and accurately locate the execution mode also obtained further, particularly, can by upgrading the URL for locating the first web page resources, and realize access to the second web page resources and acquisition by what formed after upgrading for the 2nd URL locating the second web page resources.

In embodiments of the present invention, a URL and the 2nd URL is respectively used to location first web page resources and the second web page resources, and in addition, the present invention is not limited in any way for the concrete form of a URL and the 2nd URL.

In addition, in embodiments of the present invention, renewal rewards theory described in step S702 also can have various ways, such as, as the optional mode of one, the tables of data for recording the corresponding relation between a URL and the 2nd URL can be had in client, particularly, the two can correspondingly stored in above-mentioned tables of data, and judge unsuccessful when obtaining the first web page resources by a URL in step S204, the second web page resources can be obtained by corresponding with a URL the 2nd URL from backup network.

Certainly, above-described embodiment exemplarily provides, and does not form restriction to the present invention, and such as, in embodiments of the present invention, above-mentioned renewal rewards theory can also realize by other means, and wherein, alternatively, as shown in Figure 8, step S702 can comprise:

S802: the Main Domain domain name in a URL being replaced with the territory at target web place, to form the 2nd URL, wherein, the second web page resources is pre-stored in position corresponding with the 2nd URL in the territory at target web place.

To be described in detail step S802 by a specific embodiment below.

Wherein, the access path set by the web document that target web is corresponding obtains the first web page resources in CDN, namely also a URL can as shown below:

http://cdn.com/myproject/js/10/abc.js，

Wherein, " http " may be used for representing that Data Transport Protocol is HTTP http(HypertextTransport Protocol); " cdn.com " is the domain name part in a URL, the host address for depositing the first web page resources can be represented, " myproject/js/10/ " may be used for the position that expression first web page resources is deposited in above-mentioned main frame, also namely in cdn.com territory to the path that the first web page resources conducts interviews, " abc.js " may be used for the filename representing this first web page resources, and wherein suffix " .js " can represent that the type of this file is Javascript script file.

The Main Domain in the territory at hypothetical target webpage place is " www.qq.com ", then according to step S802, an above-mentioned URL can be updated to the 2nd URL as follows:

http://www.qq.com/myproject/js/10/abc.js，

Easily notice, domain name part " cdn.com " in one URL is replaced by " www.qq.com ", if prestore the second web page resources in the position corresponding with the 2nd URL, then can judge unsuccessfully to obtain the first web page resources by a URL from CDN in step S204, also, namely after this abc.js file, identical abc.js file can be obtained by the 2nd URL from the main territory at target web place.
