Description

Web resource loading method and device

Technical field

The present invention relates to the field of mobile communication technologies, and in particular, to a webpage resource loading method and apparatus.

Background technique

With the popularity of smart mobile terminals, more and more users browse the web through the mobile terminal browser. In view of the fact that China's wireless network has not been fully covered, users use data traffic for network connection in many areas, such as in public places or during the ride.

Usually, a web page is composed of an html file and a css style file, a js style file, a picture, and the like. The html file is a main resource, and other files are sub-resources. When the mobile terminal browser is used to browse a certain webpage for the first time, the webpage file needs to be all loaded onto the mobile terminal from the server through the network for display. After the first browsing, part of the content of the webpage can be cached on the mobile terminal. Among them, because the html file changes faster, the mobile terminal browser sets the html file as a non-cacheable file, and the cacheable files are css style files, js style files, and picture files. When you browse the page again, you can only load the resources of the uncached html file part, which can increase the loading speed and save some traffic.

However, the average size of an html file in a web page is 37.55 KB, which is 12% of the page size. Therefore, although the html file is only reloaded when browsing the web page again, the loading takes a long time and the data traffic consumed is very large.

Summary of the invention

In view of this, the embodiment of the present invention provides a method and a device for loading a webpage resource, which can prevent the webpage from being repeatedly loaded when the webpage of the mobile terminal browses the webpage again, which can not only shorten the loading time but also save traffic.

In a first aspect, an embodiment of the present invention provides a method for loading a webpage resource, where the method includes: receiving request information sent by a client, where the request information includes a webpage address corresponding to the webpage resource and an original identifier corresponding to the webpage resource. The middleware server obtains the webpage resource corresponding to the webpage address, and determines the identifier of the latest version corresponding to the webpage address; when the original identifier is different from the identifier of the latest version, the original webpage corresponding to the original identifier is calculated. The difference data of the new webpage resource corresponding to the latest version of the identifier; the difference data is sent to the client, and the new webpage resource is generated by using the difference data and the original webpage resource for loading.

A second aspect, a method for loading a webpage resource, comprising: sending request information to a middleware server, where the request information includes a webpage address corresponding to the webpage resource and an original identifier corresponding to the webpage resource; and receiving the return of the middleware server The identifier of the latest version corresponding to the webpage resource, and the difference data of the original webpage resource and the new webpage resource; generating the new webpage resource by using the difference data and the original webpage resource for loading.

detailed description

In order to make the technical solution of the present invention more applicable, the present invention introduces a middleware server, which is a proxy server of a client, and puts a modification of a client and a server into the middleware server, so that the technical solution of the present invention Has good compatibility.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of a method for loading a webpage resource according to a first embodiment of the present invention. The method includes:

Step S101: Receive request information sent by the client.

When the client requests to access the A webpage for the first time, the request information includes the webpage address of the A webpage, and the middleware server obtains the webpage resource of the A webpage according to the webpage address; when the client is Nth (N is greater than or equal to 2) When accessing the A webpage, the request information includes not only the webpage address of the webpage of A, but also the identifier corresponding to the webpage resource when the webpage was last visited. The webpage address corresponding to the A webpage in the middleware server can store multiple versions of webpage resources, and each version of the webpage resource corresponds to one identifier. In the present invention, the identifier included in the request information is used as the original identifier, and the original identifier corresponds to the original identifier. The web resource is used as the original web resource.

It should be noted that the embodiment of the present invention can satisfy various application scenarios, and the client can be an intelligent mobile terminal, an IPAD, a computer, etc.; the middleware server can be set in a network that establishes a communication connection with the client.

Step S102: Determine an identifier of the latest version corresponding to the webpage resource.

The webpage resource of the A webpage is continuously updated, and each updated version generates an identifier uniquely corresponding to the webpage resource of the version. When the client accesses the webpage again, the middleware server may store multiple updated versions of the webpage A. Web resources, each updated version corresponds to an identifier. Of course, the webpage resources of the A webpage may not have an updated version at this time, and the original webpage resource is the current latest version of the webpage resource.

It should be noted that, in this embodiment, the identifier of the latest version refers to the identifier corresponding to the current latest version of the webpage resource. In the embodiment of the present invention, the latest version of the identifier may be determined from all the identifiers read by reading all the identifiers corresponding to the webpage address of the A webpage in the middleware server. It can be seen that the setting of the logo can be clearly cleared. Chu indicates whether there is an update of the webpage resource, and it is more convenient and quick to find the webpage resources of different versions by looking up the identifier.

Step S103: When the original identifier is different from the identifier of the latest version, calculate difference data of the new webpage resource corresponding to the original webpage resource corresponding to the original identifier and the latest webpage resource according to the preset rule.

Since the identifier is generated according to the content of the webpage resource, when the original identifier is different from the identifier of the latest version, the new webpage resource corresponding to the identifier of the latest version is different from the original webpage resource content corresponding to the original identifier, that is, the new webpage resource is The current version of the webpage resource, and then calculating the difference data between the new webpage resource and the original webpage resource according to a preset rule or algorithm, thereby accurately and conveniently obtaining the updated part of the webpage resource and the updated content. In this embodiment, by comparing the original identifier with the new identifier, it is determined whether the webpage resource is updated. Compared with directly comparing the webpage resources, the compared content is greatly reduced, which makes the comparison process more convenient and quick, and the operation process is simpler.

Step S104: Send the difference data to the client.

In this embodiment, only the difference data including the updated part and the updated content is sent to the client, and the client obtains the new webpage resource on the basis of the original webpage resource by using the same preset rule or algorithm as the difference data. Compared with the traditional way of loading all the updated web resources, not only can the loading time be shortened, but also the loading traffic can be greatly saved.

It should be noted that when the middleware server sends the difference data to the client, the latest version identifier corresponding to the new webpage resource may be sent to the client. When the client calculates the new webpage resource, the latest version of the identifier is used to mark the new webpage. Resources. When the client requests access to the A webpage again, the latest version of the identifier is sent to the middleware server as the original identifier.

According to the above embodiment, the webpage resource loading method provided by the embodiment of the present invention determines the webpage address when the middleware server receives the request information of the webpage address and the original identifier corresponding to the original webpage resource sent by the client. Corresponding to the latest version of the logo. When the original identifier is different from the latest version of the identifier, the new webpage resource corresponding to the latest version of the identifier is updated compared to the original webpage resource, and the difference between the original webpage resource and the new webpage resource is calculated. Data, the difference data is sent to the client. The difference data and the original webpage resource are used to generate, by the client, the new webpage resource according to the preset rule. Compared with the prior art, when the webpage resources requested by the client are updated, only the difference data of the updated part is loaded, which not only shortens the loading time but also saves traffic.

In order to enable those skilled in the art to understand the technical solutions of the present invention in more detail and clearly, the present invention is as follows. The embodiments describe the technical solutions of the present invention in detail.

FIG. 2 is a flowchart of a method for loading a webpage resource according to a second embodiment of the present invention, where the method includes:

Step S201: Receive request information sent by the client.

When the client sends the request information for the first time to access the A webpage, the middleware server searches whether the webpage resource corresponding to the webpage address is stored according to the webpage address of the webpage included in the request information, and if the webpage resource is valid, The webpage resource and its corresponding identifier are sent to the client, and details about whether the webpage resource is valid are described in the following description of the embodiment. The client saves the webpage resource and its corresponding identifier. When the client requests to access the webpage resource of the webpage again, the webpage address and the stored identifier are sent to the middleware server, when the webpage resource has a new version of the webpage resource with the updated version. The received identifier is used as the original identifier to search for the corresponding original webpage resource, and the difference data between the original webpage resource and the new webpage resource is calculated.

It should be noted that the identifiers in the embodiments of the present invention are generated by using a hash algorithm or other computer algorithms according to the content of the webpage resources. Therefore, different webpage resources correspond to unique identifiers. The generation of the identification by a hash algorithm or other computer algorithm is a technique well known to those skilled in the art, and the present invention will not be described herein.

Step S202: It is determined whether a valid webpage resource corresponding to the webpage address is stored; when it is stored, step S203 is performed; otherwise, step S211 is performed.

In this embodiment, in order to improve the utilization rate of the middleware server, the middleware server can establish a connection with multiple clients, so that the middleware server can store webpage resources of a plurality of different webpages, and each webpage corresponds to multiple different versions. Web resources. Due to the limited storage space of the middleware server and the different update speeds of some web pages, for example, the update frequency of Sina Weibo is very high, and the update frequency of the NetEase portal website is relatively low. Therefore, the webpage resources stored in the middleware server are all set to have an expiration date. In the present application, the webpage resource in the validity period is called a valid webpage resource, and when the expiration date is exceeded, the webpage resource is considered to be in an invalid state, and is called an invalid webpage resource. After the webpage resource is in an invalid state for a preset time, the middleware server clears the webpage resource, and not only can reasonably utilize the storage space of the middleware server, but also can timely update the webpage resource in the middleware server. The webpage resources corresponding to the same webpage address have the same validity period.

It should be noted that the validity period of the webpage resource can be set by the duration, and the effective duration of the webpage resources of different webpages can be set differently. For example, the effective duration of the webpage can be set to one week, and the effective duration of the microblogging website can be set to ten minutes. Similarly, the preset time to clear after the web resource is invalid can also be set by itself. Duration setting The invention can be set according to the update frequency of the webpage and the number of times of browsing, and the present invention does not limit this.

After receiving the request information of the A webpage, the middleware server searches whether the webpage resource is stored according to the webpage address, and when the webpage resource is stored, determines whether the stored webpage resource is valid, and takes different measures according to different states of the webpage resource. .

Step S203: Find all the identifiers corresponding to the webpage address.

When the webpage resource stored in the middleware server is valid, all the updated versions of the A webpage to the current reading are determined. As can be seen from the above description, many webpage resources are updated very quickly, and each time a user browses, the user must browse the latest webpage resources that the user browses. When the original webpage resource of the stored A webpage is in a valid state, the middleware server sends the currently stored valid original webpage resource to the request when receiving the request information of the other client requesting access to the A webpage for the first time. The client causes the middleware server to fail to get the latest version of the webpage resource in the state where the stored webpage resources of the A webpage are valid. In order to ensure that the user can read the latest version of the webpage resource, the middleware server periodically interacts with the target server of the A webpage during the validity period of the webpage resource of the A webpage, and when the webpage resource of the webpage has an updated version, The updated version is sent to the middleware server, and when the webpage resource of the A webpage has no updated version, the notification information is sent to the middleware server.

In this embodiment, all the identifiers corresponding to the webpage address can be found by the webpage address of the A webpage included in the request information. For example, when storing, the webpage address of the webpage can be used as the root directory, and when the webpage resource received by the terminal server is the webpage resource under the webpage address, the webpage resource is stored in the webpage address directory. When it is necessary to find all the identifiers corresponding to the webpage address, the webpage address may be first found, and then all the identifiers under the webpage address are searched, which is convenient and quick. Of course, the foregoing is only a preferred example, and the method for the present invention to find all the identifiers of the A webpage includes but is not limited thereto.

Step S204: Extract the identifier of the latest version from all the identifiers found.

In order to facilitate the extraction of the identifier corresponding to the latest version of the webpage resource of the A webpage, the middleware server can simultaneously save the time of storing each version of the webpage when storing the webpage resource, and extract the webpage resource with the latest storage time when extracting the latest version of the identifier. Corresponding identifier. At the same time, the storage time can also be used as the start time of the validity period. Or, in the storage, according to the update time of the A webpage, the identification sequence of the updated version of the webpage resource is sequentially labeled, and when the latest version of the identifier is extracted, the identifier with the largest number is directly extracted. Of course, the above is only a preferred example of the embodiment of the present invention, and imposes any limitation on the technical solution of the present invention.

Step S205: determining whether the original identifier is the same as the identifier of the latest version, if the original identifier and the identifier The identification of the latest version is different, and step S206 is performed; otherwise, step S210 is performed.

It can be seen that the identifiers of the webpage resources of different versions of the A webpage are different. In this embodiment, whether the webpage of the webpage is updated by comparing whether the original logo and the latest version of the logo are the same, if not, the latest version is indicated. The new webpage resource version corresponding to the identifier is a new version, respectively reading the new webpage resource and the original webpage resource, and calculating the difference data of the two; when the original identifier is the same as the latest version of the identifier, the original webpage resource is Currently, the latest version of the web page resource, the client directly reads the original web page resource cached by itself.

The method described in this embodiment does not need to load a large amount of data of a webpage resource regardless of whether the webpage has an updated version of the webpage resource, which saves loading time and saves traffic.

Step S206: It is determined whether the original identifier is stored. If yes, step S207 is performed; otherwise, step S214 is performed.

It can be seen from the above description that the webpage resource is set in the middleware server with a storage expiration date. When a certain client accesses the webpage again, the original webpage resource stored in the middleware server and the original webpage resource corresponding to the original identifier may be invalid, or been deleted. In particular, when the current access time is too long, the original identifier stored in the middleware server and its corresponding original webpage resource have been deleted. At this time, the original identifier is not stored in the middleware server.

It should be noted that, in this embodiment, the execution order of step S206 and step S205 may be replaced with each other. Of course, after the replacement, when the middleware server stores the original identifier, step S205 is performed. When the execution result of step S205 is that the original identifier is different from the identifier of the latest version, step S207 is performed. The execution sequence of step S205 and step S206 does not affect the implementation of the technical solution of the present invention, and will not be described in detail herein.

Step S207: Read the original webpage resource corresponding to the original identifier.

When the original identifier is different from the latest version of the identifier, the new webpage resource corresponding to the A webpage has data update with the original webpage resource. If the original webpage resource is stored in the middleware server, the original webpage resource is read to facilitate calculation of the content updated relative to the original webpage resource.

Step S208: Calculate difference data of the new webpage resource corresponding to the original webpage resource corresponding to the original identifier and the latest webpage identifier according to the preset rule.

The manner of calculating the difference data between the new webpage resource and the original webpage resource may include: calculating the file content and calculating the binary data. For example, the webpage resource corresponding to the A webpage can calculate the difference data through the file content:

The content of a part of the original webpage resource is:

OLD:

Int registerWebView(JNIEnv*env)

The content of this part of the new web resource:

NEW:

Int registerWebView(JNIEnv*env)

The generated difference file is:

@@-3,7+3,7@@WebView(JNIEnv*env,jobject javaWebView, int viewImpl,WTF::String drawableDir,

Int registerWebView(JNIEnv*env)

Wherein, -3 indicates that the original web resource file starts to change the file content on the third line, +3 indicates that the new web resource file starts to add the file content in the third line; the "-" sign indicates that the following content is deleted in the original web resource file, "+ "" indicates that the following content is added to the new web resource file, and the modified file content is the content indicated in "".

Of course, it can also be calculated in a binary manner. There are many calculation methods, and the present invention will not be repeated here, but the difference data obtained finally includes: the starting point of the difference, the length of the difference data in the original web resource file, and the new The length and content of the difference data in the web resource file. If the binary data of the original web resource file is: AAAAAAAA; the binary data of the new web resource file is: AAABAAAA, then the difference file will be recorded as: the difference data starting byte number of the original web resource file: 3, the length of the difference: 1 , the difference data starting byte number of the new web resource file: 3, the length of the difference data: 1, the content of the difference data: B.

Of course, the foregoing is only a preferred example of the present invention, and there are many methods for calculating the difference data, and the present invention will not be described herein.

Step S209: Send the difference data to the client.

It can be seen from the above embodiment that after receiving the difference data, the client obtains the new webpage resource by calculating the difference data and the original webpage resource of the A webpage according to the inverse operation of the difference data, which is not described in this embodiment.

It should be noted that when the A webpage requested by the client is a HyperText Markup Language (html) main document, it is represented by c.html in this embodiment. When the corresponding webpage resource of c.html is not stored in the middleware server, in order to avoid downloading the data of all c.html webpage resources, the client searches for an html main document with a similar webpage address under the same server that has been visited, In this embodiment, the document is recorded as d.html. The request information sent by the client includes the web address of c.html and the original identifier of d.html. The middleware server sends the webpage address of c.html to the target server, and obtains the webpage resource of c.html, and then calculates the difference data of the webpage resource of the d.html corresponding to the original webpage of the c.html webpage resource, and obtains the difference data. . The client can obtain the web resource of c.html according to the difference data and the web resource of d.html. The webpage resource of the d.html stored by the client is used as the original webpage resource, and the corresponding identifier is used as the original identifier, and the webpage resource of the received c.html is used as the new webpage resource, and the downloading c is avoided compared with the prior art. All webpage resource data of html.

Step S210: Send notification information to the client.

It can be seen from the above embodiment that when the identifier of the latest version is the same as the original identifier, the webpage resource is not updated. In order to reduce unnecessary loading, thereby reducing traffic waste, the middleware server sends a notification message to the client, notifying the client that the webpage resource is not updated, and the client reads the original webpage resource stored by itself according to the notification information.

Step S211: Send the webpage address to the server.

In this embodiment, the middleware server does not store the effective webpage resource finger, and the middleware server stores the webpage resource corresponding to the A webpage, but the stored webpage resource is invalid, or the middleware server does not store the corresponding webpage of the A webpage. Web resources. In either case, the available web resources corresponding to the A webpage are not stored in the middleware server. In order to update the webpage resources in the middleware server in time, the middleware server needs to reacquire the webpage to the target server corresponding to the webpage A. Web resources.

Step S212: Receive a new webpage resource sent by the server;

Since the target server updates the webpage resource and only stores the latest version of the webpage resource, when the middleware server sends the webpage address of the webpage to the target server, the target server sends the new webpage resource of the latest version.

Step S213: Generate an identifier of the latest version according to the new webpage resource, and execute step S205.

The target server sends the new webpage resource corresponding to the A webpage to the middleware server, and the middleware server generates the latest version of the identifier according to the content of the new webpage resource, and stores the new webpage resource and the latest version of the identifier. After the middleware server extracts the latest version of the identifier, the step of comparing the latest version of the identifier with the original identifier is performed.

Step S214: Send the new webpage resource to the client.

When the original webpage resource is not stored in the middleware server, the middleware server cannot obtain the original webpage resource according to the original identifier. When the webpage resource corresponding to the A webpage accessed this time has an updated version, the client may not be calculated based on the last access of the client. The updated part of the web resource. Even if other versions of the webpage resources are stored, the difference data obtained by other versions of the webpage resources cannot be obtained by the same rules or algorithms on the basis of the original webpage resources. Therefore, when the middleware server does not store the original identifier, the new webpage resource can only be sent to the client, and the latest version of the identifier corresponding to the new webpage resource is sent to the client, so that the client requests the next access. Used when using A webpage.

The solution described in this implementation points out that when the middleware server does not store new webpage resources, or the stored network When the page resource is invalid, the middleware server interacts with the target server, and calculates the difference data between the new webpage resource and the original webpage resource. It can be seen that as long as the original webpage resource is stored in the middleware server, when there is a new webpage resource, the client can load only the difference data of the new webpage resource and the original webpage resource without loading all the webpage resources.

Corresponding to the implementation method of the middleware server side, the present invention also shows a webpage resource loading method of the client. As shown in FIG. 3, the figure shows a flow chart of a method for loading a webpage resource loading method according to a third embodiment of the present invention.

The method includes:

Step S301: Send the request information to the middleware server.

This step corresponds to the implementation manner of the foregoing embodiment, and has been described in detail in the foregoing embodiment, and is not described herein again.

Step S302: Receive difference data sent by the middleware server.

Corresponding to the above embodiment, when the webpage resource requested by the client requests the latest version of the new webpage resource, the client only loads the data of the updated part. Certainly, the client receives the difference data and also receives the identifier of the latest version corresponding to the new webpage resource, so that the currently stored webpage resource and the identifier can accurately correspond.

Step S303: Calculate the difference data and the original webpage resource according to a preset rule to obtain a new webpage resource.

The difference data and the original web resource are obtained by using a preset rule or algorithm to obtain a new web resource. Wherein, if the preset rule for obtaining the difference data is an algorithm, the calculation of the new webpage resource by using the difference data is an inverse operation of the unified preset rule of the algorithm. The specific method for calculating the difference data has been described in detail in the above embodiments, and the operation method for performing the inverse operation on the difference data is a technique well known to those skilled in the art, and the present invention will not be described herein.

Step S304: Display content of the new webpage resource.

After receiving the new webpage resource, the client displays the new webpage resource, and writes the new webpage resource and the latest version of the identifier into the cache. When accessing again, the identifier of the latest version stored in this time is sent to the middleware server as the original identifier. If the webpage resource has an updated version, the difference data is obtained based on the newly stored webpage resource, and the amount of the difference data can be reduced. To further save load traffic.

Corresponding to the foregoing embodiment, in the embodiment, displaying the new webpage resource includes the following three situations: first, when receiving the difference data sent by the middleware server, according to the difference data and the original webpage resource stored by the client Generating a new webpage resource and reading the new webpage resource; secondly, when receiving the notification information sent by the middleware server, it indicates that the webpage resource requested by the client does not have an updated version, and the client directly reads the original webpage stored by the client. The resource can be; thirdly, when receiving the new webpage resource sent by the middleware server, the client directly reads the new webpage resource and simultaneously stores the new webpage resource.

As can be seen from the embodiment, only when the middleware server does not store the webpage resources requested by the client, the client needs to load the complete webpage resource, and the webpage resources frequently accessed by the user are stored in the middleware server. That is to say, in the webpage resource loading method of the embodiment of the present invention, even if the update frequency of the webpage resource with a high user access rate is high, the webpage resource data is not required to be loaded frequently, and the amount of data loaded is greatly reduced, thereby further reducing the amount of data loaded. The traffic consumption of the client.

The above description shows that the webpage resource loading method provided by the embodiment of the present invention determines that the webpage address corresponds to when the middleware server receives the request information including the webpage address and the original identifier corresponding to the original webpage resource sent by the client. The latest version of the logo. When the original identifier is different from the latest version of the identifier, the new webpage resource corresponding to the latest version of the identifier is updated compared to the original webpage resource, and the difference between the original webpage resource and the new webpage resource is calculated. Data, the difference data is sent to the client. The difference data and the original webpage resource are used to generate, by the client, the new webpage resource according to the preset rule. Compared with the prior art, when the webpage resources requested by the client are updated, only the difference data of the updated part is loaded, which not only shortens the loading time but also saves traffic.

Corresponding to the foregoing implementation method, the embodiment of the present invention further provides a webpage resource loading device, as shown in FIG. 4, which is a schematic structural diagram of a first embodiment of a webpage resource loading device according to an embodiment of the present invention. The device includes: a receiving unit 11, a determining unit 12, a calculating unit 13, and a sending unit 14, wherein the receiving unit 11 is configured to receive request information sent by the client, where the request information includes a webpage corresponding to the original webpage resource. An original identifier corresponding to the original webpage resource; the determining unit 12, configured to determine an identifier of a latest version corresponding to the webpage address; the calculating unit 13 is configured to: when the original identifier and the latest version When the identifiers are different, the difference data of the new webpage resources corresponding to the original webpage resource corresponding to the latest version of the original identifier is calculated according to the preset rule; the sending unit 14 is configured to send the difference data to The client, the difference data and the original webpage resource are used to generate, by the client, the new webpage resource according to the preset rule.

The implementation process of the functions and functions of each unit in the device is described in the corresponding implementation process in the above method. This will not be repeated here.

The webpage resource loading device of the embodiment determines the identifier of the latest version corresponding to the webpage address when the middleware server receives the request information of the webpage address and the original identifier corresponding to the original webpage resource sent by the client. When the original identifier is different from the latest version of the identifier, the new webpage resource corresponding to the latest version of the identifier is updated compared to the original webpage resource, and the difference between the original webpage resource and the new webpage resource is calculated. Data, the difference data is sent to the client. The difference data and the original webpage resource are used to generate, by the client, the new webpage resource according to the preset rule. Compared with the prior art, when the webpage resources requested by the client are updated, only the difference data of the updated part is loaded, which not only shortens the loading time but also saves traffic.
