Detailed description of the invention

Elaborate a lot of detail in the following description so that fully understanding the application.But the application can implement being much different from alternate manner described here, and those skilled in the art can do similar extension when without prejudice to the application intension, therefore the application is by the restriction of following public specific embodiment.

In the embodiment of the present application, three kinds of Internet resources acquisition methods and devices for loading web page and a kind of method and apparatus for buffer network resource are each provided.In order to make it easy to understand, first the technical scheme of the application is described briefly.

The browser of mobile terminal device is when loading web page, it will usually by http protocol from the Internet resources loaded needed for Network Capture, owing to network interaction process ratio is relatively time-consuming, thus causing that web page loading velocity is generally slow.And the technical scheme that the embodiment of the present application provides, the mode carrying out asynchronous process, employing prestrain resource bag and self-defined buffer memory by some blocks the request of page rendering increases the chance obtaining Internet resources from this locality and to modes such as network request low resolution pictures under weak net environment, it is effectively improved the loading velocity of web page, promotes Consumer's Experience.

Internet resources described herein, it is possible to refer to the various resources being stored in network service end, for instance, html file, picture, text, Javascript script, css pattern file etc., generally adopt URL address information to label.Browser uses the URL information of Internet resources to be loaded, obtains corresponding Internet resources from service end, is finally presented the web page comprising Internet resources by render process to user.

Compared with wire transmission mode, wireless network transmissions speed is barely satisfactory all the time, cause that the drawback that web page loading velocity is slow on mobile terminals is more prominent, therefore, the technical scheme of the application is primarily directed to what mobile terminal device proposed, but be not limited to that this application, at the terminal unit adopting wire transmission mode, such as: desktop PC, the technical scheme of equally possible employing the application, to improve the speed of browser loading web page.

The embodiment below the application provided is described in detail one by one.Refer to Fig. 1, its first flow chart being used for loading the embodiment of the Internet resources acquisition methods of web page being the application.Described method comprises the steps:

Step 101: obtain the URL information that request comprises according to the Internet resources from browser, judge whether described request meets following condition: this request is the obstructive request producing page rendering to block, and needs the Internet resources obtained to have no effect on page rendering according to this request；If so, step 102 is performed.

Browser loads the process of web page, usually resolve html document, generation DOM (DocumentObjectModel DOM Document Object Model) tree, render tree and the process drawn out by web page by traversal render tree, commonly referred to as page rendering process.In this process, if it find that contain network resources address in html document, browser will send, to network service end, the request obtaining Internet resources.

Owing to browser typically requires stable DOM tree structure; and the Internet resources obtained from network service end likely change the structure of dom tree or affect render process; such as javascript performs the operations such as document.write; in order to avoid analogue occurs; browser would generally adopt the mode of obstruction to send described request to network service end; that is: the render process of web page is suspended; until being further continued for performing subsequent operation after receiving the response of network service end and obtaining described Internet resources, thus causing that page loading procedure is slow.

But in actual motion, above-mentioned obstruction waits being not all required, for this situation, it is possible to adopt the mode of asynchronous acquisition Internet resources to improve the loading velocity of web page.Specifically, obtain, according to the Internet resources from browser, the URL information that request comprises, it is judged that whether described request can block page rendering and requested Internet resources have no effect on page rendering.Such as, browser adopts the mode blocking page rendering to initiate certain request obtaining Internet resources, is intended merely to one data statistics of acquisition, and this information both will not export at the page, nor affects on the render process of the page.In such a case, it is possible to according to the rule made an appointment, according to some particular content (such as, Hostname etc.) that URL information comprises, forward step 102 to after identifying this kind of request and carry out asynchronous process.

It should be noted that, browser described in this step sends Internet resources acquisition request to network service end and can also include carrying out once mutual with network service end, and really do not obtain the situation (it is believed that being sky from the Internet resources of service end acquisition) of Internet resources, in this case obstructive request also complies with the above-mentioned requirement not affecting page rendering, and asynchronous system can be adopted too to process.

Step 102: return asynchronous process response to browser so that it is proceed page rendering.

Asynchronous process described in this step, is for the method for synchronization waiting network service end return response, i.e. without waiting for the feedback of service end, directly return response to browser, thus browser can proceed page rendering.And real network request operation performs in step 103.

In an object lesson of the present embodiment, described method can be implemented in the UIWebView that iOS operating system is built-in, when initiating the request of acquisition Internet resources to network side every time, method as follows is called in capital, therefore can by the rewriting of the method realizes the technical scheme of the application:

-(id)webView:(id)param1resource:(id)param2willSendRequest:(id)param3redirectResponse:(id)param4fromDataSource:(id)param5

The method is used for realizing the redirection (below the method being called for short reorientation method) of NSURLRequest, and wherein, param3 is the NSURLRequest representing this network request, and return value is NSURLRequest type.

In the method, first pass through param3 and obtain HTTP request mode, because the operation obtaining Internet resources is generally all GET request, if HTTP request mode is POST, then only need to call the parent system approach that the method provides, the URL information of request is otherwise obtained by param3, determine whether to block the request that html page renders by this information, and the resource of this request will not relate to rendering of html page, if, direct return type is the NSURLRequest response of nil, so that the render process of web page continues executing with, without being in blocked state.

Step 103: obtain described Internet resources from service end.

After returning response to browser, then perform to obtain from service end the operation of described Internet resources, obtain described Internet resources specifically by the mode sending HTTP request and reception http response to service end.In the specific implementation; consider that browser would generally send the request of a series of acquisition Internet resources at short notice in the process loading web page; inevitably cause the contention to the network bandwidth; cause and block up; in order to alleviate this situation, the Asynchronous Request operation of this step can take the mode of delay process, for instance; postpone 1 second or several seconds, thus reducing network congestion to improve bandwidth efficiency.

Described above is process obstructive request being carried out to asynchronous process, on this basis, when the judged result of step 101 is "No", the embodiment of the present application also provides for obtaining Internet resources from local prestrain resource bag, obtain Internet resources from local self-defined buffer memory and from such three preferred implementations of the low-definition version of Network Capture picture resource, and these three preferred implementation can be mutually combined, and illustrates one by one below.

(1) Internet resources are obtained from local prestrain resource bag.

Described prestrain resource bag contains stability height (i.e. amendment frequency low) and the higher static resource file of client-access frequency, by these resources are prestored to this locality, thus when loading relevant web page, required Internet resources can be obtained from this locality, avoid sending request to network and receiving the interaction of response, reach to improve the purpose loading web page speed.

Described prestrain resource bag is stored in advance in this locality.In an object lesson of the present embodiment, mobile terminal device, when downloading the client application of built-in browser function from service end, downloads the prestrain resource bag corresponding with described client application in the lump.In order to improve page loading velocity, avoid taking too much memory space simultaneously, in the present embodiment, can only select javascript, css file of the HTML5 homepage relevant to described client application and javascipt, css of comprising and picture and two, three grades of pages, this is because homepage is the page that access frequency is the highest, two, javascript, css file of three grades of pages is the resource file that stability is higher, but two, the picture resource of three grades of pages is dynamically change, and therefore this type of resource is not put in prestrain resource bag.

After obtaining described prestrain resource bag from service end, a series of Internet resources files that prestrain resource bag is comprised, it is stored in advance under prestrain catalogue set in advance, and each Internet resources file is using the MD5 value of the URL information of respective network resource as its filename.

Consider Internet resources often dynamic mapping, renewal, in order to, while improving web page loading velocity, show up-to-date network resource information to user, it is also possible to described prestrain resource bag is dynamically updated as far as possible.

Specifically, according to certain time interval, the edition configuration file of described prestrain resource bag is obtained from service end, the network version number of described prestrain resource bag is extracted from described edition configuration file, namely the version number that described prestrain resource bag is currently up-to-date, then described network version number and the version number of local prestrain resource bag are compared, if it find that the prestrain resource bag of this locality has not been latest edition, the download information then provided according to described edition configuration file, obtains the up-to-date prestrain resource bag corresponding with described network version number.In being embodied as, the interval performing above-mentioned renewal operation can be configured as required, for instance performs once every twenty four hours.

While obtaining the prestrain resource bag of latest edition, generally also can download the MD5 check code of correspondence in the lump, therefore can at the MD5 check code of the prestrain resource bag of local computing redaction, then compare with the MD5 check code downloaded, if it is consistent, the prestrain resource bag that redaction is then described is complete, correct, it is possible to is stored under described prestrain catalogue by the Internet resources file wherein comprised, replaces original Internet resources file under described catalogue；Otherwise, illustrate that the prestrain resource of redaction wraps in network transmission process damaged, in this case, it is possible to reacquire according to the download information that described edition configuration file provides.

The foregoing describe the process at locally stored prestrain resource bag and regular update, due to locally stored prestrain resource bag, therefore when the judged result of step 101 is "No", can determine whether whether locally stored prestrain resource bag comprises described Internet resources, namely, URL information according to requested Internet resources, calculate corresponding MD5 value (that is: MD5 character string), and by described MD5 character string as filename, under described prestrain catalogue, search whether there is corresponding document.

If existing, then illustrate locally stored prestrain resource bag comprises described Internet resources, so avoid the need for again from Network Capture, it is possible to directly from the corresponding document found under described prestrain catalogue, obtain described Internet resources, and be supplied to the browser loading procedure for web page.

In the object lesson that the present embodiment step 102 provides, in the reorientation method of described UIWebView, after judging locally stored prestrain resource bag comprises described Internet resources, the corresponding document found in this locality is utilized to build NSURLRequest response, and by the type identification of this response be: resource is obtained from this locality, being then back to this response, browser will obtain described Internet resources and load from this locality.

(2) from local self-defined buffer memory, Internet resources are obtained.

Why adopt self-defined buffer memory, it is based on considered below: major part browser all possesses caching function at present, but a lot of buffer memorys carrying out Internet resources all without the cache-time specified according to http protocol, such as: although the UIWebView of iOS system carries system cache (i.e. NSURLCache), but it is because mobile terminal device internal memory and disk is limited, in order to save resource, cache-time is generally much less than the cache-time that http protocol scheme provides, if twice HTTP request is slightly larger for interval time, so system cache will discharge cache resources, cause that local hit rate declines.

For this problem, the present embodiment achieves the self-defined buffer memory of this locality according to the principle of http protocol buffer memory: for the Internet resources obtained, it is stored in the form of a file in the self-defined CACHE DIRECTORY that this locality pre-sets, and follow http protocol and carry out setting and the management of cache-time, such that it is able to improve Internet resources in local hit rate.

In order to realize above-mentioned functions, it is possible to the Internet resources obtained from service end are stored in local self-defined buffer memory, specifically includes: receive http response information, calculate the expired time point of buffer memory and storage Internet resources file these three processing procedure.Illustrate separately below.

1) the http response information comprising Internet resources that service end returns is received.

Described http response generally comprises response head and response body part, response head comprises the information such as type of server, date-time, content type and length, response body part generally comprises requested Internet resources, for instance: html source file or other kinds of resource data.

2) effective duration of the buffer network resource comprised according to described http response information, calculates the expired time point of buffer memory of Internet resources described in buffer memory.

In the specific implementation, can before calculating the expired time point of buffer memory, from http response head, first extract the information of mark resource type, judge whether the type of Internet resources obtained is type set in advance, if, then calculate the expired time point of buffer memory and perform further cache operation, if it is not, the Internet resources not comprised in http response information described in local cache.Described type set in advance may include that text/css, image/png, application/x-javascript, image/jpeg, image/gif etc..

Effective duration of the buffer network resource that described http response information comprises refers to, the value of the max-age field in http response head, this information in seconds, is a relative time span, and http protocol adopts the duration that the Internet resources of this information instruction body part can be buffered.

Therefore can extract the value of max-age field the value according to this field from http response information, calculate the absolute time that described Internet resources are expired, it may be assumed that the expired time point of buffer memory described herein.

In specific implementation process, it is also possible to do some sweetly disposition.Such as, some static CDN resource expired time that http protocol provides may be one month even 1 year, if carrying out buffer memory fully according to http protocol, too many memory space can be taken, particularly the disk resource of mobile terminal device is more limited, consider page loading velocity and taking memory space, if the buffer memory duration that http response provides (value of max-age field) is more than the largest buffered time set in advance, such as: 7 days, the described largest buffered time then can be adopted as buffer memory duration, and calculate the expired time point of corresponding buffer memory.Certainly, 7 days given here is a specific example, in different implementation processes, it is possible to be adjusted correspondingly according to concrete demand.

In specific implementation process, the largest buffered time can also be pre-set, for instance, it is possible to it is set to 7 days, when the buffer memory duration obtained from http response information is more than the described largest buffered time, then adopt the expired time point of buffer memory described in described largest buffered Time Calculation.

3) the described Internet resources that described http response information comprises are stored in described self-defined CACHE DIRECTORY in the form of a file, and expired for described buffer memory time point are write in the attribute field being used for recording last modification time of described file.

After obtaining the expired time point of buffer memory of the Internet resources that http response provides, the MD5 value of the URL information of described Internet resources can be calculated, and using described MD5 value as filename, the Internet resources that described http response information comprises are stored in described self-defined CACHE DIRECTORY in the form of a file.

After Internet resources described in buffer memory, also should store the expired time point of buffer memory of these Internet resources, in order to when obtaining Internet resources from this locality, can interpolate that whether effectively (not out of date) described Internet resources.Memory buffers expired time point has multiple method, in order to save disk resource, present embodiments provide a kind of preferred implementation, in attribute field that expired for the buffer memory of described Internet resources time point is stored in respective file, that be used for recording last modification time, namely in NSFileModificationDate field, thus both having reached the purpose of record buffer memory expired time point, avoid again taking additional storage space.

Further, in order to avoid taking too much memory space, the present embodiment additionally provides the mechanism of the cleaning to self-defined buffer memory.Specifically, according to certain time interval (or when starting the application program using self-defined buffer memory) every time, each file in described self-defined CACHE DIRECTORY is checked: from the attribute field (that is: NSFileModificationDate field) being used for recording last modification time of described file, extract the expired time point of buffer memory；Judge the expired time point of described buffer memory whether early than or equal to current time；If so, from described self-defined CACHE DIRECTORY, described file is deleted.Adopt in this way, it is possible to delete the scratch file in self-defined buffer memory in time, thus the file ensured in self-defined buffer memory is all valuable.

By above-mentioned 1), 2), 3) three processing procedures, achieve the function of buffer network resource in local self-defined buffer memory, therefore when the judged result of step 101 is "No", can determine whether whether described Internet resources store and not out of date in local self-defined buffer memory, namely, URL information according to requested Internet resources, calculate corresponding MD5 value (i.e. MD5 character string), and by described MD5 character string as filename, under the catalogue that described self-defined buffer memory is corresponding, search corresponding document.

If finding, buffered described Internet resources in local self-defined buffer memory are described, for recording, the attribute field of last modification time extracts the expired time point of buffer memory from the corresponding document found, judge whether the expired time point of described buffer memory is later than current time, if, the described resource file of storage in local self-defined buffer memory is described and not out of date, it is possible to directly from local self-defined buffer memory, obtain described Internet resources, and be supplied to the browser loading procedure for web page.

In the object lesson that the step 102 of the present embodiment provides, in the reorientation method of described UIWebView, after judging local self-defined buffer memory comprises described Internet resources, the corresponding document found in this locality is utilized to build NSURLRequest response, and by the type identification of this response be: resource is obtained from this locality, being then back to this response, browser will obtain described Internet resources and load from this locality.

(3) from the low-definition version of Network Capture picture resource.

Compared with text or code word resource, picture resource generally ratio is obtained relatively time-consuming from network service end, particularly become apparent under weak net environment, present embodiment by obtaining the mode of low resolution picture resource under weak net environment, network latency can be reduced, can quickly from the picture resource needed for Network Capture, thus improving the speed loading web page.

Described weak net environment is a relative concept, and is not limited to wireless network, it is common that refer to that network transfer speeds or network transmission quality (such as: packet loss) are lower than the network setting threshold value.For mobile terminal device, the network transmission environment being provided without wifi transmission technology may be considered weak net environment, such as, current 2G network transfer speeds is relatively slow, network transmission quality is relatively poor, may be considered vulnerable network, but, along with the development of network technology, defining of vulnerable network also can be varied from.

In the specific implementation, it is possible to the built-in function provided by system or interface function realize the monitoring to weak net environment.Such as, iOS system carries SystemConfiguration.framework storehouse, the interfaces such as informing function when providing acquisition current network conditions, monitor network environment and network state change is set, utilize above-mentioned interface just can know and be currently at wifi or non-wifi network state, thus determining whether weak net environment.

Present embodiment first determines whether whether the URL information of described Internet resources comprises the suffix of the mark picture/mb-type such as jpg, png or jpeg, if comprised, illustrate that described Internet resources are picture resources, then determine whether whether current network transmission environment meets weak net environment set in advance, if meeting, then obtained the low-definition version of described picture resource from service end by following three process.

1) URL information according to described picture resource, adopts matching regular expressions mode to judge whether described picture resource meets replacement condition set in advance；If so, subsequent operation is continued executing with.

Regular expression, also known as conventional expressing method (RegularExpression), use single character string to describe, mate a series of character string meeting certain syntactic rule, in a lot of text editors, regular expression is usually used to retrieval, replaces the text meeting certain pattern, and many programming languages are all supported to utilize regular expression to carry out string matching operation.

In actual applications, picture resource has been done the cutting of various sizes size by a lot of CDN server, the picture resource of corresponding various resolution is provided, the URL information simultaneously adopting specific format identifies this kind of resource, URL information according to requested picture resource in this step, matching regular expressions mode is adopted to judge whether described picture resource meets replacement condition set in advance, i.e. to judge whether described picture resource is the resource with low-definition version.

In the above-mentioned object lesson of the present embodiment, replacement condition set in advance is: the host corresponding for URL of described picture resource is any one in www.taobaocdn.com, www.tbcdn.cn or www.alicdn.com these three CDN server, and URL is with the ending of "-digital-digital " form, the width value of two numerals representative pictures respectively therein and height value.The URL information of requested picture resource is: http://img.taobao.com/bao/uploaded/i3/TB1WwKyFVXXXXbjXXXXdBVzVF XX-630-418.jpg, adopt regular expression that the form of above-mentioned URL information is mated, meet replacement condition set in advance, therefore can continue executing with follow-up operation.

2) URL information of corresponding low resolution picture resource is generated according to Substitution Rules set in advance.

According to 1) in carry out matching regular expressions as a result, it is possible to extract resolution information from the URL information of described picture resource, for instance, the width value of described picture resource and height value；Then, described width value and height value are respectively divided by proportionality coefficient set in advance, obtain new width value and height value；According to described new width value and height value, choose corresponding resolution parameter according to picture tailoring rule set in advance；Finally, generate the URL information of described picture resource according to selected resolution parameter, namely obtain the URL information of described corresponding low resolution picture resource.

In the above-mentioned object lesson of the present embodiment, the width of described picture resource is 630, height is 418 (unit of width and height is all pixel), proportionality coefficient set in advance is 2 (adopting the strategy that resolution reduces by half), therefore obtaining new width value is 315, and new height value is 209；Picture resource is divided into multiple rank according to resolution by image cropping set in advance rule, each rank has different width values and height value, search wherein with new width value 315 and new peak angle value 209 closest to scheme, obtain this resolution of 200x200, thus generating the URL information of low resolution picture resource as follows: http://img.taobao.com/bao/uploaded/i3/TB1WwKyFVXXXXbjXXXXdBVzVF XX-630-418.jpg_200x200.jpg.

3) newly-generated URL information is used to obtain the picture resource of described low resolution to service end.

Picture resource to Network Capture low resolution, specifically, send the HTTP request obtaining picture resource to service end, this request use 2) the middle URL information generated, and receive the http response that service end returns, wherein comprise the low-definition version of described picture resource.

Certainly, if described Internet resources are not pictures or are unsatisfactory for above-mentioned replacement condition set in advance or current network conditions is not weak net environment, then directly described Internet resources can be obtained to network service end.

So far, the present embodiment is on the basis that obstructive request carried out asynchronous process, it is further provided three kinds of preferred implementations.In specific implementation process, these three preferred implementation can individually be implemented, it is also possible to combines enforcement, for instance, if Internet resources obtain request and are unsatisfactory for adopting the condition of asynchronous process, then can first judging whether local prestrain resource bag has described Internet resources, if having, loading from this locality, otherwise judge whether local self-defined buffer memory has described Internet resources again, if having, loading from this locality, otherwise continuing to attempt to the low-definition version from Network Capture picture resource.

In sum, the Internet resources acquisition methods for loading web page that the present embodiment provides, if it is determined that Internet resources obtain request, for obstructive request, requested Internet resources have no effect on page rendering, then directly return asynchronous process response to browser, continue to carry out page rendering, then obtain described Internet resources from service end again, such that it is able to reduce browser to wait the time of network answer, improve the loading velocity of web page.Simultaneously on the basis of above-mentioned Asynchronous Invocation, the present embodiment additionally provides the mode obtaining described Internet resources in local prestrain resource bag and self-defined buffer memory, and the mode from Network Capture low resolution picture resource, such that it is able to significantly more improve the loading velocity of web page, effectively promote Consumer's Experience.

After the method provided by the present embodiment is implemented in the client application adopting iOS operating system, the speed that built-in browser is loaded web page by tester has carried out strict test, test result shows, under weak net environment, the loading velocity of web page improves 3 times, and under wifi environment, the loading velocity of web page improves 2 times.
