In general, in embodiments of the present invention, the above-mentioned web access requests to target webpage usually may come from The identification clicked to the link of the direction target webpage in browser or user interface, also, one kind as Internet resources, The web page files of above-mentioned target webpage can usually pass through uniform resource position mark URL (Uniform Resource Locator) It is positioned, for example, in some embodiments of the invention, to there are URL hyperlink in above-mentioned browser or user interface The capture and identification of mouse click action on passage can form web access requests.Certainly, above-mentioned direction target The link of webpage can also be not present on text, but in other browsers such as icon, picture, video pictures or user interface In element on, this is not limited by the present invention.

It is worth noting that, being a kind of relatively conventional performance shape of web access requests described in above-described embodiment Formula, rather than necessary embodiment, for example, in some embodiments of the invention, the generations of web access requests can also be with The input signal for reading from computer input device is unrelated, for example, the web access requests can be by being currently running in client Application automatically generate, with formed to the pop-up page on browser or user interface, such as the access of navigation page, the present invention couple This is not limited in any way.

Based on the above-mentioned access request to target webpage, the access to target webpage may be implemented, however, since format limits System, web document itself corresponding with target webpage are typically not enough to cover all information content of presentation needed for it.

In general, target webpage can usually show as hypertext markup language html(Hypertext Markup Language) the web document of format, and can by the different elements edited in the web document, such as text, Image, audio, video, interactive form etc. define the specific presentation mode of target webpage, so as to show not in webpage The information of same type, and realize the interaction with external information.

Wherein, a part of inside that can be directly recorded in above-mentioned web document in above-mentioned web page element, by loader, Browser or user interface etc. are loaded directly into, and another part can utilize web document in such a way that external resource links The calling to these web page resources is realized in the chained address of the web page resources of the outside for being present in the web document of middle record, And be further advanced by loader, browser or user interface etc. and be loaded into target webpage, to constitute above-mentioned web page element.Its In, the chained address of above-mentioned web page resources can generally also show as URL, however this is not limited by the present invention.

As previously mentioned, in the prior art, the web page resources of the above-mentioned outside for being present in web document can be stored in Data link is shorter between web page access terminal, on node of the faster CDN of data transmission bauds, wherein the node can be used In indicating a domain in computer network, it can also indicate that a computer or server therein etc. have basic data The storaging medium of processing function.Wherein, above-mentioned be stored in CDN node can be used for mesh convenient for following description The web page resources of mark webpage load are denoted as the first web page resources.

Specifically, corresponding with above-mentioned web page element, the first web page resources can also there are many type, such as text, picture, Video file etc., and its file format can also there are many, for example, relatively conventional, may include Javascript script or Cascading style sheets CSS(Cascading Style Sheet) type file etc., the present invention do not do any restriction to this, answers It is interpreted as feasible any form of web page resources.

It is worth noting that, in embodiments of the present invention, target webpage can be remembered according in corresponding web document The URL of first web page resources of record calls first web page resources, however the first web page resources corresponding with the URL might not Necessarily be stored in scheduled position in CDN, for example, by the data dump of CDN server or update operation, can by this first Web page resources are deleted from CDN, or are updated and arrived other addresses or path, that is, in some embodiments of the invention, client Can be to the first web page resources of CDN request, however first web page resources can also be not present in above-mentioned CDN.It needs Illustrate, above-mentioned scene has no effect on the implementation of technical solution of the present invention, also should not be construed as constituting the present invention any It limits.

The web page resources acquisition methods provided according to embodiments of the present invention, as shown in Fig. 2, in step S204, Ke Yi After above-mentioned the first web page resources to CDN request, judge whether successfully to obtain first web page resources.

In general, the acquisition request of above-mentioned first web page resources can be shown as through corresponding URL to first The access of web page resources is called in other words, wherein for ease of description, by the above-mentioned chained address for being used to position the first web page resources It is defined as the first URL.

Specifically, in the above scenario, CDN for the response of above-mentioned web page resources acquisition request generally may include with Lower four kinds of situations:

1) CDN responds web page resources acquisition request, and sends client for the first web page resources；

2) CDN responds web page resources acquisition request, and there are the first web page resources corresponding with the first URL, but Client is sent by the first web page resources not successfully；

3) CDN responds web page resources acquisition request, but the first web page resources corresponding with the first URL are not present；

4) CDN does not respond web page resources acquisition request.

Wherein, for the first situation, it can be determined that going out successfully to obtain first web page resources namely client can be with Web page resources normally are obtained from CDN and realize the access to complete target webpage, obtain webpage money from CDN in view of client The scheme in source belongs to technical solution mature in the prior art, and the present invention does not make tired state herein.

For second case, specifically, in some embodiments of the invention, can pacify from the network of client Full setting, such as firewall, downloading shielding, the limitation of resource access being arranged in client or the domain locating for it etc., to lead Cause CDN after the acquisition request for receiving the first web page resources, the browsing that the first web page resources can not be sent in client Device or user interface etc., so as to judge to obtain first web page resources not successfully.

For the third situation, as previously mentioned, in some embodiments of the invention, the first web page resources can be stored in Position other than first URL, for example, the access path of the first URL is changed in the update operation of CDN server, Deng the first web page resources can not be sent to client so as to cause CDN, also may determine that obtain first net not successfully Page resource.

It, specifically, in some embodiments of the invention, can be from storage the first webpage money for the 4th kind of situation The access of node in the CDN in source is arranged, for example, visit of the user other than the white list for forbidding the node to be arranged to the node It asks, fails to make a response the acquisition request of the first web page resources so as to cause CDN, should also be judged as and obtain described not successfully One web page resources.

For above situation, it can be judged respectively to obtain whether successfully obtain first web page resources Judging result, however, on the other hand, the above-mentioned judgement operation for whether successfully obtaining first web page resources can also with Family setting is unrelated with network environment, for example can be monitored in the port that client is specified, and is sending web page resources with detection After acquisition request, if success receives the first web page resources from CDN.

Certainly, above embodiments are a kind of example, in embodiments of the present invention, can also by other means to whether Success obtains the first web page resources and is judged, optionally, as shown in figure 3, step S204 may include:

S302: judge whether that successfully the first web page resources are loaded into target webpage, wherein

If so, S304 is thened follow the steps,

If it is not, thening follow the steps S306；

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

S306: judge to obtain the first web page resources not successfully.

In general, browser or loader will be according to target webpage institutes during accessing to target webpage Corresponding web document pulls the first web page resources, and after successfully obtaining the first web page resources, is loaded into and is in In target webpage in present browser or user interface, thus, in embodiments of the present invention, the first web page resources can be passed through Load success or not judgement as a result, to determine whether success from CDN obtain the first web page resources, wherein if target webpage The first required web page resources are loaded successfully into target webpage, then may determine that load operation before client at Function obtains the first web page resources from CDN, if the first web page resources needed for target webpage are loaded into target webpage not successfully, The reason of then no matter loading unsuccessfully comes from the failure of the acquisition to the first web page resources in CDN or browser or loader Load failure can be considered as the first web page resources of acquisition that fail, so as to turn to backup network in step S206 The second web page resources of request.

It is worth noting that, in some embodiments of the invention, the load for the web page resources based on html label Mode, loading action synchronous with the acquisition request of web page resources can carry out, specifically, for example, for the first web page resources For the situation of Javascript script file, can by html label as follows to the Javascript script file into Row load:

Wherein, "<script></script>" can be used to indicate that in html label<script>label, which can With the file for defining script type, wherein

Type attribute can be used for providing the multipurpose internet mail extensions MIME (Multipurpose of the script file Internet Mail EXtensions) type, wherein " javascript " can be used to indicate that the type of the script file is Javascript script file;

Charset attribute can be used for providing the character code mode of the Javascript script file, for example, above-mentioned " utf-8 " can be used to indicate that Unicode coding mode;

Src attribute can be used for being directed toward external script files namely the Javascript script file, and can pass through The assignment of Src attribute provides the access path of the Javascript script file, wherein the access path is usually expressed as this The URL of Javascript script file, " script.js " as escribed above.

From the above, it can be seen that passing through above-mentioned html<script>label to as the first web page resources During Javascript script file is loaded, due to defining the Javascript script file by Src attribute Access path, and it can be accessed and be called according to the path, so as to be considered as while load to first Web page resources propose the request of acquisition.

It is worth noting that, for the loading method of the web page resources based on static html label, since it is difficult to The stress state of accurate judgement script, so that in some embodiments of the invention, JS (Javascript) load can be used Device loads Javascript script file, in the above scenario, as shown in figure 4, optionally, step S302 can wrap It includes:

S402: judge whether that the Javascript script file is successfully loaded into the target webpage by loader In.

Wherein, common JS loader has very much, for example, can be the loader based on script DOM mode, it can also Think the loader based on ajax eval mode and other feasible can be used for judging that Javascript script file is The loader that no success loads, this is not limited by the present invention.

Similarly, it is the situation of CSS file for the first web page resources, again may be by html label and it is added It carries, for example, the html label can be with are as follows:

< link rel=" stylesheet " href="/css/master.css " type=" text/css " Media=" screen " chaset=" utf-8 " >,

Wherein, "<link>" can be used to indicate that<link>label in html label, the label can be used for defining net Relationship between page document and the web page resources of outside, and it is commonly used for link shape table, such as CSS file, wherein

Type attribute can be used for providing the mime type of the external web page resource, wherein " text/css " can be used for Indicate that the linked web page resources are CSS file；

Rel attribute can be used for providing the linking relationship between above-mentioned web document and the CSS file, wherein " stylesheet " can be used to indicate that link shape table；

Media attribute can be used for providing that the linked CSS file will be shown in what kind of equipment, for example, Above-mentioned " screen " can be used to indicate that be shown in PC equipment；

Charset attribute can be used for providing the character code mode of the CSS file, for example, above-mentioned " utf-8 " can be with For indicating Unicode coding mode；

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

Similarly, by above-mentioned html<link>label the CSS file as the first web page resources is being loaded In the process, it due to defining the access path of the CSS file by Href attribute, and can be accessed according to the path to it And calling, the request of acquisition is proposed to the first web page resources while load so as to be considered as.

As shown in figure 5, being the situation of CSS file for the first web page resources, step S302 can in embodiments of the present invention To include:

S502: the predetermined time period after needing the first web page resources to be loaded into CDN request target webpage It is interior, judge in target webpage specify document dbject model DOM node whether successfully load recorded in CSS file with The corresponding the preset style of DOM node,

If so, S504 is thened follow the steps,

If it is not, thening follow the steps S506；

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

S506: judge to load CSS file not successfully in target webpage.

Wherein, DOM is as a kind of standard programming interface, referring to its regulation, in embodiments of the present invention, in web document Each ingredient can be considered as a DOM node, for example, the DOM node can be the entirety of web document, or on That states is used to link the html label of external web page resource, can also be the web page element recorded in web document, such as wherein Text or html attribute, etc..

In embodiments of the present invention, it can be the specified pattern of one or more DOM node settings in CSS file, make For above-mentioned the preset style, and the indicator for successfully loading the CSS file is judged whether with the preset style, attempting to this After CSS file is loaded, whether successfully acted in target webpage according to indicator, to determine whether CSS file loads into Function.Specifically, for example, the sentence pair of the following form in CSS file can be passed through as one of optional embodiment DOM node is configured:

Object { visibility:hidden },

Wherein, whether visible visibility attribute can be used for regulation object element, wherein " hidden " can be used In indicating that the element is invisible, for example, being the situation of " head " for object, can set the pattern of title to can not See, so as to pass through the inspection of the pattern to the title in the predetermined time period after request loads the CSS file It surveys to judge whether the CSS file successfully loads, wherein if the title is invisible, may determine that CSS file successfully adds Carry, if the title as it can be seen that if may determine that CSS file loads not successfully.

It should be noted that in embodiments of the present invention, to the first web page resources, such as above-mentioned Javascript script text The load that part or CSS file carry out, it should be understood that the request of load, wherein above-mentioned Javascript script file or CSS text Part can be not stored in CDN, be loaded into target webpage not successfully after can also being obtained or be obtained by client not successfully, from And request failure can be considered as.For above-mentioned scene, it should not be construed as the description with technical solution of the present invention and form to conflict.

Furthermore it is noted that in the above-described embodiments, for the first web page resources load movement can with obtain The movement taken is synchronous to be carried out, however this has no effect on the implementation of web page resources acquisition methods according to an embodiment of the present invention, does not answer It is interpreted as foring with technical solution of the present invention and conflict, also should not be construed as constituting the present invention restriction, and still should be regarded as Within protection scope of the present invention.

The web page resources acquisition methods provided according to embodiments of the present invention can be according to step S204 in step S206 Judging result, not successfully obtain the first web page resources when, from other than the CDN backup network obtain with the first webpage provide Consistent second web page resources of the content in source.

In embodiments of the present invention, it except the first web page resources that can be stored in CDN, is stored in backup network Second web page resources, wherein the content of the second web page resources can be consistent with the first web page resources, for example, of the invention another In some embodiments, the backup that the second web page resources can be used as the first web page resources is stored in backup network, however this hair It is bright that this is not construed as limiting.

The situation of the first web page resources can not be obtained from CDN for above-mentioned client, it can be determined that go out failed to obtain the One web page resources, so as to obtain the second web page resources from the backup network other than CDN, wherein second in step S206 The backup that web page resources can be used as the first web page resources is stored in advance in above-mentioned backup network, in case the tune of target webpage With so as to form a kind of optional implementation environment of web page resources acquisition methods according to an embodiment of the present invention, such as Fig. 6 institute Show.

Similar to the first web page resources, the file format of the second web page resources, the information type for being included and its specific table Existing form can also there are many selections, it is however generally that, can be identical as the first web page resources, so that target webpage is can not be from When CDN obtains the first web page resources, it can be obtained by intimate consistent web page resources acquisition request and web page resources loading method It takes and loads the second web page resources.However this is not meant to that the present invention has made restriction to this, for example, of the invention some In embodiment, the second web page resources can also show as to the first web page resources optimize processing after be stored in backup network In web page resources, for example, the web page resources by compression processing or format optimization processing, consequently facilitating webpage in backup network The storage and management of resource.Certainly, above only a kind of example, the present invention are not limited in any way this.

On the other hand, the storaging medium as the second web page resources, backup network can also there are many implementation, The storage equipment that can be embodied in the network other than CDN, can also show as combination, the equipment group of multiple devices Conjunction is formed by computer domain or a wider computer network, the present invention are 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 therein are pre-stored in, For example, the computer network for having the second web page resources can be considered as above-mentioned backup network.Certainly, on the other hand, back up Network is it may be specified beforehand that multiple second webpages for storing the backup as web page resources needed for target webpage provide Source, wherein optionally, backup network can specify as the network area where target webpage, thus can be to target webpage Under the premise of accessing, it can obtain relevant second web page resources in consolidated network region, and then reached raising net The technical effect of the reliability of access to web page.

Particularly, in some embodiments of the invention, backup network can also be appointed as in above-mentioned the first webpage of storage Other CDN except the CDN of resource, wherein the backup for the first web page resources stored in other above-mentioned CDN can be considered as Second web page resources can be realized to the from other above-mentioned CDN thus in the case of the first web page resources can not be obtained successfully The acquisition of two web page resources, wherein what other above-mentioned CDN also can be selected as being closer to the client of specified network area The combination of CDN node, so as under the premise of improving the reliability of web page access, further decrease since the first webpage provides Source, which fails, obtains the influence of caused webpage access speed decline.

However, it should be understood that technical solution of the present invention can also with known to those skilled in the art other are feasible Technological means be combined with each other,, can also be with for example, for the orientation of other above-mentioned CDN to obtain more preferably technical effect Pass through domain name system DNS (Domain Name System) Lai Shixian.It should be noted that similar to technical solution of the present invention Deformation, expand and its and the combinations of other common technology means be formed by technical solution and embodiment is regarded as in this hair Within the scope of bright protection.

As shown in fig. 6, in the above scenario, when client is difficult to obtain the first web page resources from CDN, can by from Consistent second web page resources of content with the first web page resources are obtained in backup network, are solved in the prior art when client hardly possible Be difficult to load corresponding with web page resources web page element in target webpage caused by when obtaining web page resources from CDN thus It is caused to be difficult to the technical issues of normally being accessed target webpage, realize that the technology normally accessed target webpage is imitated Fruit, 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 and send to CDN The corresponding concept of web page resources acquisition request, that is, the first web page resources are interpreted as with the webpage of load needed for target webpage The web page resources to CDN request on the basis of element, therefore, the web page resources in CDN are updated or other types Data processing after the change for the first web page resources that occurs, it is standby such as in the case of the first web page resources are deleted Consistent second web page resources corresponding with the deleted content of the first web page resources still saved in part network, it should be appreciated that To meet the second web page resources described in technical solution of the present invention, implementation condition of the invention is had no effect on, also should not be understood To constitute restriction to the present invention.

Optionally, as a kind of specific embodiment, as shown in fig. 7, in step S206, it is above-mentioned other than CDN Backup network is obtained may include: with consistent second web page resources of content of the first web page resources

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

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

By above embodiments, a kind of implementation second web page resources being accurately positioned and further obtain is provided Mode can specifically be formed by being updated to the first URL for positioning the first web page resources, and after passing through update Access and acquisition of the 2nd URL realization to the second web page resources for position the second web page resources.

In embodiments of the present invention, the first URL and the 2nd URL is respectively used to the first web page resources of positioning and the second webpage money Source, in addition to this, the present invention are not limited in any way the concrete form of the first URL and the 2nd URL.

In addition, in embodiments of the present invention, the operation of update described in step S702 can also there are many mode, for example, As a kind of optional mode, can there be the number for recording the corresponding relationship between the first URL and the 2nd URL in client According to table, specifically, the two can be stored in above-mentioned tables of data correspondingly, and judge to pass through first not successfully in step S204 When URL obtains the first web page resources, the can be obtained from backup network by the 2nd URL corresponding with the first URL Two web page resources.

Certainly, above-described embodiment is provided as example, and limiting the invention, for example, in the embodiment of the present invention In, above-mentioned update operation can also be realized by other means, wherein optionally, as shown in figure 8, step S702 may include:

Domain name in first URL: being replaced with the Main Domain in the domain where target webpage by S802, to form the 2nd URL, In, the second web page resources are pre-stored in position corresponding with the 2nd URL in the domain where target webpage.

Step S802 will be described in detail by a specific embodiment below.

Wherein, the corresponding web document of target webpage carries out obtaining set access to the first web page resources in CDN Path namely the first URL can be as shown below:

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

Wherein, " http " can be used to indicate that Data Transport Protocol is hypertext transfer protocol http(Hypertext Transport Protocol)；" cdn.com " is the domain name part in the first URL, can be indicated for storing the first webpage money The host address in source, " myproject/js/10/ " can be used to indicate that the position that the first web page resources are stored in above-mentioned host It sets, namely the path to access in the domain cdn.com to the first web page resources, " abc.js " can be used to indicate that first net The filename of page resource, wherein suffix " .js " can indicate that the type of this document is Javascript script file.

It, then, can will be above-mentioned according to step S802 assuming that the Main Domain in the domain where target webpage is " www.qq.com " First URL updates the 2nd URL being as follows:
