Background

With the increasing requirements for network environment, more and more clients are capable of shielding web page contents. Such as the screening of illegal contents such as sensitive information, yellow-related information, etc., and also the screening of promotion contents (such as advertisements). However, the promotion content on the web page is an important income source for the web page manager, and the promotion content is also an important channel for marketing, promotion and information dissemination of relevant merchants.

Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 illustrates an exemplary system architecture of an anti-blocking method or apparatus for web page content to which an embodiment of the present invention may be applied.

As shown in fig. 1, the system architecture may include a client and a server. The client installed and running on the terminal device may be a client such as a browser capable of rendering and presenting a webpage to a user. The client may interact with the server over a network. Wherein the network may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few. The terminal device may be various electronic devices capable of installing and operating the client. Including but not limited to smart phones, tablets, smart televisions, and the like.

In the application, the client can request the web page content from the server and render the web page content. The server may embed a web script, such as a js (javascript) script, in the web content sent to the client. The web script can be executed in the terminal device.

The webpage content anti-shielding device can be arranged and operated on the server side, and the server side can also issue partial functions to the webpage script to realize the webpage content anti-shielding device. It may be implemented as a plurality of software or software modules, or may be implemented as a single software or software module, and is not particularly limited herein. The server may be a single server or a server group consisting of a plurality of servers.

Fig. 2 is a flowchart of a main method provided in an embodiment of the present application, and as shown in fig. 2, the method may include the following steps:

in 201, the shielding information of the web page content by the client is analyzed by monitoring the change of DOM (Document Object Model) in the rendered web page content.

This step may be performed by a web script. And after the page is issued to the client, executing the webpage script embedded in the webpage. After rendering the web page content, the client often uses some shielding methods to shield part of the web page content. Therefore, the webpage script conducts DOM monitoring on the rendered webpage content. On one hand, whether the client shields the webpage content or not is determined, and on the other hand, the shielding mode adopted by the client to the webpage content is determined.

In particular, the web script may monitor changes to the DOM through, for example, a MutationObserver interface, which provides the ability to monitor changes made to the DOM tree.

Generally, the shielding modes adopted by a client to shield webpage content mainly include three types:

the first is to remove a DOM node of a specific type, for example, remove a DOM node corresponding to promotion information.

The second method is to change the style of a DOM node of a specific type, for example, to change the style of the DOM node corresponding to the promotion information into transparent.

The third is to intercept a request of a specific path, for example, an access request of a specific domain name.

At 202, a rendering log is collected, the rendering log including client-side shielding information for web page content.

The recording of the rendering log may be performed by a web script. The webpage script records the rendering log according to the rendering condition of the webpage content. Wherein rendering the log may include presenting the log and masking the log. The presentation log may record presentation information of the web content, and the mask log may record information of the web content masked by the client, which may include, for example, a masked web content identifier, client information, and a masking manner.

The maintenance of the rendering log can be executed by a log platform of the server, namely, each webpage script reports the rendering log recorded by the script to the log platform in real time or at regular time. And maintaining and counting by the log platform.

In 203, the rendering log is monitored to replace the anti-shielding policy according to the shielding information of the client on the webpage content.

The step is executed by the server, wherein the monitoring of the rendering log can be executed by a log platform of the server, and the replacement of the anti-shielding strategy can be executed by a configuration platform.

The specific implementation of this step may include, but is not limited to, the following three ways:

the first mode is as follows: the server monitors the rendering log to determine shielded webpage contents with shielded conditions meeting preset first preset requirements, and the shielded webpage contents are replaced by the shielding prevention strategy.

The log platform can monitor the presentation log and the shielding log respectively to determine the shielding rate of the shielded content and determine the shielded webpage content with the shielding rate higher than a preset shielding rate threshold. The presentation log and the number of screening times may also be monitored to determine a presentation rate of the screened content, and to determine the screened web page content having a presentation rate lower than a preset presentation rate threshold. In addition, masked web page content whose masking number exceeds a preset threshold may also be used, and the like, which are not exhaustive herein.

For example, if the number of times a promotional message is displayed and the number of times b a promotional message is masked, the display rate may be

Shielding ratio of

In this way, if a piece of promotional information (e.g., an ad slot) is frequently masked, it indicates that the current anti-blocking policy for the promotional information has been broken by a plurality of clients, and the anti-blocking policy needs to be changed for the promotional information. Namely, when responding to the webpage access request containing the promotion information, the replaced anti-shielding strategy is adopted.

The second mode is as follows: the server monitors the rendering log to determine the client type of which the shielding condition of the webpage content meets a second preset requirement.

Similarly, the log platform can monitor the display logs and the shielding logs, count the shielding condition of each client type on the specific webpage content, and change the anti-shielding strategy for the client type if the shielding rate of a certain client type on the specific webpage content is higher than a preset shielding rate threshold value. Or if the presentation rate of a certain client type to specific webpage content is lower than a preset presentation rate threshold, replacing the anti-shielding strategy for the client type. Or if the shielding times of a certain client type to specific webpage contents exceed a preset shielding time threshold, replacing the anti-shielding strategy for the client type. And so on.

Because the shielding modes of the same type of client for specific webpage content such as promotion information are generally consistent, if the promotion information is frequently shielded by a certain type of client, the anti-shielding policy for the type of client is considered to be invalid, and the anti-shielding policy needs to be replaced for the type of client. Namely, when responding to the webpage access request of the client, the replaced anti-shielding strategy is adopted.

The third mode is as follows: the server monitors the rendering log and counts the shielding condition of each type of client to each webpage content; and if the shielding condition of a certain client type on certain webpage content meets a third preset requirement, replacing the anti-shielding strategy aiming at the access request of the client type on the webpage content.

Due to the fact that shielding capabilities of the client sides are stronger and stronger, the client sides can often adopt different shielding modes according to different webpage contents, and therefore shielding conditions of various webpage contents can be counted according to various client side types. For example, if the blocking rate of the client type 1 on the ad spot a exceeds a preset blocking rate threshold, or the presentation rate of the client type 1 on the ad spot a is lower than a preset presentation rate threshold, or the like, the anti-blocking policy may be changed for the combination of the client type 1 and the ad spot a. Namely, when responding to the webpage access request containing the advertisement space a by the client type 1, the replaced anti-shielding strategy is adopted.

In this step, the mode of replacing the anti-shielding strategy can adopt, but is not limited to, the following two modes:

the first mode is as follows: and issuing the replaced anti-shielding strategy configuration information through the configuration platform, reading the configuration information by the webpage script and executing the replaced anti-shielding strategy.

The configuration platform may configure the replaced anti-blocking policy configuration information for the masked web content, the configuration information is sent along with the web page, and the web script reads the configuration information and executes the replaced anti-blocking policy.

When the anti-shielding strategy configuration information is sent, the configuration field can be added. For example, the format of the configuration field is:

${type}_${num}_${value}

the type value may be 0 or 1,0 representing a general policy mechanism and 1 representing a policy mechanism customized by the developer. The num value is used for indicating the identification of the anti-shielding strategy, and the value is the content of the anti-shielding strategy.

That is, some general anti-shadowing strategies may be employed in the system for use and selection. In addition, developers can flexibly develop some private anti-shielding strategies according to actual conditions and then issue the strategies through a configuration platform.

The second mode is as follows: and issuing a webpage script adopting the replaced anti-shielding strategy in the webpage.

The log platform, the configuration platform, and the like are logically divided, and may be implemented by being installed on one server of the server, or by being installed on a plurality of servers.

The "client" referred to in the embodiments of the present application may be a browser, or may be other clients capable of rendering and presenting web page content. In the following embodiments of the present application, a browser is described as an example.

The web content targeted by the anti-blocking in the present application may be a specified type of web content, and the following embodiments of the present application are described by taking the popularization content as an example.

Fig. 3 is a flowchart of a detailed method provided by an embodiment of the present application, and as shown in fig. 3, the method may include the following steps:

in 301, after the webpage is sent to the browser for rendering, the webpage script monitors DOM changes corresponding to the rendered promotion content to analyze whether the browser shields the promotion content; if not, executing 302, namely recording the display log, uploading to a log platform, and turning to 304; if so, 303 is performed.

The webpage script can monitor DOM changes corresponding to the rendered promotion content through the MutationObserver interface, so as to determine whether the promotion content is shielded and a specific shielding mode.

And if the browser does not shield the promotion content, recording a display log. For example, an identification of the promotional content, a browser identification, a presentation time, etc. may be recorded.

In 303, the webpage script analyzes the shielding mode adopted for the promotion content, records the shielding log, and uploads the shielding log to the log platform.

The shielding mode can include: removing the DOM node corresponding to the promotion content, changing the DOM node style corresponding to the promotion content and intercepting a request of a specific path.

The web script records a shielding log, such as the identification of the promotion content, the identification of the browser, the shielding mode, and the like. In the embodiment of the application, the logs are uploaded to a log platform for unified maintenance no matter the logs are displayed or shielded.

At 304, the log platform maintains rendering logs including presentation logs and mask logs, collects and accounts the rendering logs.

And the log platform monitors the maintained rendering logs and monitors and counts the shielding condition of the popularization content of each browser. The monitoring and counting of the shielding status of the promotion content by each browser may include counting of indexes such as shielding rate, presentation rate, shielding times and the like of the promotion content. In this embodiment, the statistical masking rate is taken as an example.

Statistics may be performed, for example, using the data format shown in table 1 below:

TABLE 1

Browser identification	Promotion content identification	Number of masks	Number of presentations
				Browser 1	Popularization content a	80	20
Browser 1	Popularization content b	2	88
				Browser 2	Popularization content a	60	40
Browser 2	Popularization content b	55	45
				…	…	…	…

In 305, if the shielding rate of a certain type of browser for a certain promotion content exceeds a preset shielding rate threshold, the developer side device is notified of the information of the shielding of the promotion content by the browser of the type.

Continuing with the example shown in table 1, assuming that the preset shielding rate threshold is 80%, it can be seen from table 1 that the shielding rate of the browser 1 on the promotion content a reaches 80%, and then the developer-side device may be notified with a message that the shielding rate of the browser 1 on the promotion content a reaches 80%.

The device at the developer side can be notified by means of a method such as mail, short message, etc., and the identification of the promotion content such as being masked, the identification of the browser, the masking method, etc. are notified.

In 306, the anti-shielding policy is replaced for the access request of the browser to the promotion content, and the configuration platform issues the replaced anti-shielding policy configuration information to the webpage script.

Continuing with the example shown in table 1, the anti-blocking policy may be replaced for the combination of browser 1 and promotion content a, and the replacement of the anti-blocking policy needs to be determined according to the shielding manner adopted by browser 1 for promotion content a. Accordingly, when the browser 1 responds to the webpage access request containing the promotion content a, the replaced anti-shielding strategy is adopted,

the format of the configuration information may be the same as that described in the first embodiment, and is not described herein again. The manner in which the anti-blocking strategy is replaced is described in detail herein, and may specifically include, but is not limited to, the following:

the first mode is as follows: and writing DOM style information of the promotion content in a line. The tags are commonly used tags such as div, span, h 1-h 6, etc., the tags are prohibited from using id or class, etc., and Inline Styles (Inline Styles) are used.

The second mode is as follows: the style name indicating the promotion information is disabled. Usually, when the browser is used for shielding promotion content, matching is performed through a keyword "ad" and the like, so that the style name of the "ad" and the like can be forbidden.

The third mode is as follows: and replacing the label shielded with the promotion information. For example, if the original promoted content uses a div tag, but is recognized and masked by the browser, the promoted content may be replaced with a h1 tag or the like.

The fourth mode is that: the masked web page content is rendered asynchronously. When the promotion content is shielded by a plurality of browsers, the DOM corresponding to the promotion content is changed or removed after the webpage content is rendered. If an asynchronous rendering mode is adopted for the promotion content, namely after rendering is completed on other webpage contents except the promotion content, the promotion content is requested to be obtained and rendered from the server, and therefore the shielding difficulty of the browser on the promotion content is increased.

The fifth mode is as follows: the insertion location of the masked web page content is changed. If the browser shields the promotion content according to the DOM position of the promotion content, the DOM position of the promotion content can be replaced.

At 307, the web script reads the anti-blocking policy configuration information and executes the replaced anti-blocking policy. Proceed to execution 301.

And after the webpage script reads the anti-shielding strategy configuration information, executing the replaced anti-shielding strategy according to the configuration information in the executing process.

In the application, a mode of issuing the anti-shielding policy configuration information by the configuration platform is taken as an example, in addition, a mode of directly issuing a webpage script which adopts the replaced anti-shielding policy can be adopted, so that the replaced anti-shielding policy is executed during execution.

After the anti-blocking policy is changed, the web script proceeds to 301 to perform the process of listening for DOM changes and logging.

The above is a detailed description of the method provided in the present application, and the following is a detailed description of the apparatus provided in the present application with reference to the embodiments.
