Description

A page updating method and device

technical field

The invention relates to page data processing technology in the field of computers, in particular to a page update method and device.

Background technique

With the continuous development of Internet information technology, more and more smart terminals, such as smart phones, laptops, tablets, smart watches, etc., have been developed and widely used in all aspects of life; Applications (APP, Application) on a terminal can be classified into native applications, web applications, and hybrid applications.

Among them, the native application refers to an application developed specifically for a certain type of smart terminal. For example, an application developed for the IOS operating system or an application developed for the Android operating system can be called a native application, and such applications can be Run directly on the operating system of the corresponding smart terminal; Web application, in simple terms, refers to an application designed and developed based on a browser, and the Web application can use the browser on the smart terminal, such as the IE browser in the windows system , Safari browser in the iPhone to run, and such applications run on various operating systems; and hybrid applications, as the name implies, refer to the combination of native applications and Web applications. It can be seen that hybrid applications have both native and web applications. Applications and web applications are usually characterized by embedding one or more web view (Web View) in the application, and loading web page data through the Web View.

While the APP on the smart terminal is running, the page displayed by the APP client for the user often undergoes various updates, such as the icon, picture or text content displayed on the page currently displayed by the client is updated, etc. , and this situation is more common in hybrid applications and web applications.

At present, in order to achieve the purpose of updating the page displayed by the APP client, it is often necessary for the APP client to request the server for the full amount of data of the updated page, and download the full amount of data of the updated page to the local APP client, and then according to The downloaded page data regenerates the page and loads the updated page for the user. Take the hybrid application as an example. When the user uses the hybrid application, the web application part in the hybrid application will send a request to the server at all times to detect whether the currently displayed page is updated. When it detects that the currently displayed page is updated, the APP client The terminal will request all the data of the updated page from the server, and download all the data to the local APP client, and then regenerate the updated page according to the downloaded page data, and display it to the user.

Obviously, the above-mentioned existing page update method usually needs to download the full amount of data of the updated page every time the page is updated, which will cause a waste of user traffic; in addition, when the user's current network When the environment such as 2G network is poor, it often takes a long time to download the full data of the updated page to the local client, and during the full data download process, the APP client may not be able to display the updated page for the user , or only the page before the update can be displayed to the user, resulting in a poor user experience.

Embodiment one

As shown in Figure 1, the implementation process of the page update method in the embodiment of the present invention includes the following steps:

Step 101: Pre-acquire the full amount of page data stored locally;

Here, the page data can be divided into several different types of data, for example: text type page data, image type page data, style type page data, etc., so that the APP client can Data, determine the style and layout of the display page, and determine the specific display content on the display page according to the text type data and image type data in the page data, so as to render and generate a full display page according to the obtained page data.

After performing this step, the method further includes: dividing the full amount of page data into at least two sub-page data according to different types of page data, and each sub-page data corresponds to a unique identifier.

It should be noted that the unique identifier used here can facilitate the distinction of each subpage data divided in the full amount of page data, that is, a unique identifier can be set for each subpage data in the full amount of page data; the unique identifier can be either a subpage The package name of the compressed package corresponding to the page data can also be a string obtained by encrypting the subpage data through an encryption algorithm such as MD5. Therefore, any variable that can uniquely represent the subpage data can be used as the subpage data. Unique identifier for page data.

Step 102: The APP client sends a query request for updating data to the server, and the query request carries identification information, and the identification information is used for the server to determine whether the page data currently requested by the APP client is updated, and in the Determine the updated page data when it is judged that there is an update;

Here, the query request carries identification information such as unique identifiers of different types of subpage data that have been downloaded to the local APP client, and location identifiers of different types of subpage data in the display page.

Here, this step specifically includes: carrying the unique identifier of each subpage data in the query request, and the unique identifier of the subpage data is used for the server to compare with the unique identifier of the corresponding type of subpage data stored locally , and determine the page data corresponding to the changed unique identifier as the updated page data; or,

The location information of each displayed page after updating is carried in the query request, and the location information is used for the server to compare whether the page data in the same location area of the displayed page before and after the update are the same, and will be changed in the same location area The page data of is determined as the updated page data.

Step 103: The APP client generates an updated display page according to the updated page data and the full amount of locally stored page data.

Here, after performing this step, the method further includes: loading the updated display page and displaying it to the user.

Here, the APP client can use various existing or new rendering technologies to generate an updated display page according to the updated page data and the full amount of locally stored page data, which is not limited here.

Using the page update method provided by the embodiment of the present invention, when updating the page, only the updated page data needs to be downloaded. Compared with the existing page update method that needs to download the full data of the updated page, the present invention The embodiment obviously saves network traffic and download resources for users, improves page response speed, and greatly improves user experience.

Embodiment two

The specific implementation process of the page update method in the embodiment of the present invention will be further described in detail below.

Fig. 2 provides a schematic diagram of the specific implementation flow of the page update method of the embodiment of the present invention, as shown in Fig. 2, including the following steps:

Step 201: When the APP client is started for the first time, the APP client will send a request for downloading data to the server, and download the full amount of page data from the server;

Generally speaking, the page data mainly includes: the main document page (page), and data related to the display of the display page, for example, cascading style list (CSS, Cascading Style Sheet) data, image data, text data, etc. And these different data can play different functions when the APP generates a display page. Therefore, the page data can be divided into several different types of data, such as text-type page data, image-type page data, and style-type page data. In this way, the APP client can determine the style layout of the displayed page according to the style type data in the downloaded page data, and determine the specific content displayed on the displayed page according to the text type data and picture type data in the page data, thereby Generate a full display page based on the downloaded page data rendering.

For example, after the APP client completes the layout of the display page according to the CSS style file in the page data, it can further load the text type data and picture type data in the page data through Web View, so as to achieve the purpose of generating the display page .

Here, after the full amount of page data is downloaded from the server, the full amount of page data is divided into at least two sub-page data according to different types of the page data.

It should be noted that, in order to facilitate the distinction of each subpage data in the full amount of page data, a unique identifier can be set for each subpage data in the full amount of page data; the unique identifier can be the package of the compressed package corresponding to the subpage data It can also be a string obtained by encrypting the subpage data through an encryption algorithm such as MD5. Therefore, as long as the variable can uniquely represent the subpage data, it can be used as the unique identifier of the subpage data. In addition, when the APP client downloads the full amount of page data from the server, it will correspondingly download the unique identifier of each subpage data included in the full amount of page data, and save the full amount of page data and the unique identifier of each subpage data to the APP client local.

Step 202: When starting the APP again, the APP client sends a query request for updating data to the server;

Here, the query request may carry identification information such as unique identifiers of different types of subpage data that have been downloaded locally to the APP client, and location identifiers of different types of subpage data in the display page.

Step 203: Determine the updated page data according to the identification information carried in the query request;

Step 204: Generate an updated display page according to the updated page data and the full amount of page data downloaded locally in advance;

Specifically, when the APP client sends a query request for updating data to the server, the query request carries the unique identifiers of different types of sub-page data that have been downloaded locally to the APP client. In this way, the server receives the APP After the query request for updating data sent by the client, the unique identifier of the subpage data carried in the query request can be compared with the unique identifier of the corresponding type of subpage data stored locally to determine the current request of the APP client. Whether the page data of the APP client is updated, when there is at least one unique identifier not included in the query request among the unique identifiers of the subpage data saved in the server, it is determined that the page data currently requested by the APP client has been updated, and then the server Send the updated page data to the APP client.

Taking the page data as picture type data as an example, the process of determining the updated page data will be described in detail below.

For example, the APP client sends the query request for updating data to the server to carry the unique identifiers of picture type data as 1, 2, 3, 4, 5, while the unique identifiers of picture type data in the page data saved in the server are 1, 2, and 3, the server compares the unique identifier carried in the query request for updating data with the unique identifier of the picture type data saved in the server, and can determine that the page data currently requested by the APP client has been updated, and also That is to say, the page data uniquely identified as 4 and 5 is the added page data, or incremental page data, which is the updated page data. At this time, the page data corresponding to the unique identification 4 and 5 will be sent to the APP client. Here, the page data corresponding to the unique identifiers 4 and 5 can be displayed on the original page data, that is, above and below the page data corresponding to the unique identifiers 1, 2, and 3, or can be displayed on the page data corresponding to the unique identifiers 1, 2, and 3. The left and right sides of the corresponding page data, the present invention does not specifically limit here, it only needs to make the updated page data corresponding to the unique identifiers 1, 2, 3, 4, 5 complete and neat on the display page of the terminal display.

As another example, Figure 3 shows a schematic diagram of a display page before updating. As shown in Figure 3, the APP display page in the figure includes 7 pictures from A to G. Here, A to G can be used as distinguishing pictures unique identifier of . When the APP is started for the first time, the client corresponding to the APP has downloaded the data about the pictures A~G from the server. When using the APP later, the pictures on the display page can be generated according to the data of the pictures A~G downloaded in advance. A~G. Assuming that during a certain page update process, picture A is updated to picture 1. Here, the area occupied by picture A and picture 1 is the same size, and pictures B~G remain unchanged. After the update, when the user starts the APP again , the APP client will first send an update data query request to the server to check whether the display page of the APP has been updated. After the server determines that the APP has been updated and the updated page data is picture 1, The APP only needs to download the page data used to generate picture 1 from the server, and then based on the newly downloaded data of picture 1 and the data of pictures B~G downloaded to the local area in advance, it can be rendered and generated as shown in Figure 4 The updated display page.

Here, various existing or new rendering technologies can be used to generate updated display pages according to the newly downloaded data of picture 1 and the data of pictures B-G downloaded locally in advance, which is not limited here.

In addition, it needs to be pointed out that, for the case where the area occupied by picture A and picture 1 is different in size, after updating picture A to picture 1, the terminal system needs to automatically calculate the positions of the updated pictures 1, B-G Re-adjust the page layout so that the display page of the terminal can be displayed perfectly and neatly. Here, various existing or new adjustment methods may be used to adjust the page layout of the updated pictures 1, B-G positions, which are not limited here.

It should be noted that the page data is still image type data as an example, except that the unique identifier carried in the query request for updated data can be compared with the unique identifier of the corresponding type of page data saved in the server to determine the updated In addition to the page data, the updated page data can also be determined according to the location area of the picture on the display page. Wherein, the position area where the picture is located on the display page refers to the position area occupied by each complete picture in the display page generated by the APP.

Specifically, when the page data saved in the server is updated, the server can determine the location area occupied by each picture in the updated display page according to the updated page data, and the APP can also determine the location area occupied by each picture in the updated display page according to the locally saved page data before the update. Page data to determine the location area occupied by each picture in the display page before updating, and then when the APP client sends a query request for updating data to the server, it can carry the occupied area of each picture in the display page before updating in the query request By comparing the image data in the same location area on the displayed page before and after the update to determine whether the updated page data is the same.

Similarly, the style of the APP display page can also be updated according to the above method. For example, the display page of an APP before updating is shown in Figure 3. The display page includes 7 pictures from A to G, as well as "Home", There are 4 application icons of "Order", "Favorites" and "My". If when Christmas is approaching, the research and development personnel responsible for the APP designed a Christmas-style display page style for the APP, and uploaded the update package to the background server of the APP client, then when the user starts the APP again after the update, The APP client will send a query request for updating data to the server to download the Christmas-style display page style that needs to be updated this time from the server, and render the incremental page data downloaded after the update and the display page style data pre-saved locally. The updated display page is generated, as shown in Figure 5, in which the four application icons of "Home", "Order", "Favorites" and "My" in Figure 5 are updated to Christmas-style icons.

What needs to be emphasized here is that the above is an example of restarting the APP after the display page of the APP is updated, and introduces the page update method provided by the embodiment of the present invention, but it can be understood that the method provided by the embodiment of the present invention The page update method can be implemented not only when the APP is started, but also when the page of the already started APP is refreshed. For example, during the use of the APP, assuming that the background server corresponding to the APP updates the display page of the APP, then The user can refresh the page so that the APP downloads the updated page data from the server through the above-mentioned page update method provided by the embodiment of the present invention when refreshing the page, and then can download the updated page data according to the updated page data and the locally saved page data. , rendering and generating an updated display page, and displaying the updated display page after the page is refreshed, which will not be described in detail here.

Step 205: the APP client refreshes and loads the updated display page, and presents the updated display page to the user.

Using the page update method provided by the embodiment of the present invention, when updating the page, only the updated page data needs to be downloaded. The example obviously saves network traffic and download resources for users, improves page response speed, and greatly improves user experience.
