[0055] In order to facilitate the understanding and explanation of the technical solutions provided by the embodiments of the present application, the background technology of the present application will be described below.

[0056] When a user uses a client to browse a web page, the page may be a white screen. The white screen does not include valid information. When the client displays a white screen, it is difficult for the user to continue to access the page, and the user can only revisit the page to try, which reduces the user's experience. At present, when the client detects that the user triggers the display of a new page, the displayed page is detected as a white screen. This type of method can only perform white screen detection on newly visited pages. However, during the operation of the page, the page may also be a white screen. The above-mentioned method for performing white screen detection on newly visited pages is difficult to detect the white screen that appears during the operation of the page, and it is impossible to fully detect the problem of the page being a white screen. In addition, the current method of white screen detection needs to record the changes in HTML (Hyper Text Markup Language) during a period of time when the page is displayed, which consumes a large amount of client operating resources.

[0057] Based on this, an embodiment of the present application provides a white screen detection method. In this method, in response to detecting a change in a page element, the client determines a white screen score based on the page elements included in the currently displayed page. If the white screen score meets the initial judgment condition, the client sends the page information of the page used to judge again to determine whether the page is a white screen to the server. The server can determine whether the page is a white screen by using the page information of the acquired page. By detecting changes in page elements, the client can achieve a more comprehensive white screen detection during the page display process. In addition, the client performs an initial white screen detection on the page, which can reduce the resources consumed by the client to detect the white screen and reduce the cost of the client to detect the white screen. The client and the server perform white screen detection on the page in turn, which can improve the confidence of the white screen detection and reduce the false alarm rate of the white screen detection.

[0058] In order to facilitate understanding of the white screen detection method provided in the embodiment of the present application, the white screen detection method provided in the embodiment of the present application is described below in conjunction with the accompanying drawings. Figure 1 See the example scenario shown in the figure. Figure 1 As shown, this figure is a schematic diagram of an exemplary application scenario provided in an embodiment of the present application.

[0059] Those skilled in the art will understand that Figure 1 The schematic diagram shown is only an example in which the embodiments of the present application can be implemented. The scope of application of the embodiments of the present application is not limited in any aspect by this framework.

[0060] The white screen detection method provided in the embodiment of the present application is applied to a client and a server. The client is used to display a page. The server is connected to the client to detect the white screen.

[0061] The client pre-configures the Blank Screen SDK (Software Development Kit). The Blank Screen SDK is used to detect the white screen. The Blank Screen SDK encapsulates the white screen detection algorithm module. The Blank Screen SDK calls the white screen detection algorithm module when detecting a change in the page elements. The Blank ScreenDetect algorithm module is used to determine the white screen score based on the page elements included in the currently displayed page. Among them, the white screen score is used to measure the complexity of the page elements. Based on the white screen score, it is possible to make an initial judgment on whether the page is a white screen. If the white screen score meets the initial judgment condition, the client sends the page information of the page to the server. The page information, for example, includes a page image obtained by the client screenshot module encapsulated by the Blank Screen SDK for performing a screenshot operation on the page, or includes an HTML string of the page. In the case where the page information includes an HTML string, the server uses the configured server image generation SDK to render the page based on the HTML string, and takes a screenshot of the page to obtain a page image. The server uses the white screen detection model to process the page image to obtain a white screen detection result of the page.

[0062] In order to facilitate understanding of the technical solution provided in the embodiment of the present application, the white screen detection method provided in the embodiment of the present application is described below with reference to the accompanying drawings.

[0063] See also Figure 2 As shown in FIG. 1 , the figure is a schematic diagram of the process of the white screen detection method provided in the embodiment of the present application, such as Figure 2 As shown, the method may include S201-S202:

[0064] S201: In response to detecting a change in a page element, the client determines a white screen score based on page elements included in a currently displayed page.

[0065] The client is a client that displays web pages, such as a browser.

[0066] The client detects changes in page elements during page display. Page elements are elements that constitute a page. Page elements include, for example, text, buttons, controls, and other elements displayed on the page. Changes in page elements, as an example, include changes in page elements displayed by a page caused by a page jump. A page jump may be, for example, a page jump triggered by a user, or a page jump automatically triggered by a client. As another example, changes in page elements include changes in page elements triggered by user operations on the page or a preset display method when the page has not jumped.

[0067] The embodiments of the present application do not limit the implementation method of the client detecting changes in page elements.

[0068] In a possible implementation, the client detects the structure of the DOM (Document Object Model) tree of the page. Figure 3 As shown, this figure is a flow chart of a white screen detection method provided by an embodiment of the present application. DOM is a programming interface for HTML documents and XML (EXtensible Markup Language) documents. DOM defines a standard method for accessing and manipulating HTML documents. HTML DOM expresses HTML documents in a tree structure. The DOM tree is used to describe the hierarchical structure of page elements included in the page. The DOM tree includes DOM nodes at different levels. The DOM nodes correspond to the page elements included in the page. If the page elements included in the page change, the structure of the DOM tree corresponding to the page will change. The client detects the changes in the page elements by detecting the structure of the DOM tree of the page. The embodiment of the present application does not limit the method of detecting the structure of the DOM tree of the page. In one implementation method, the MutationObserver (change observer) API (Application Programming Interface) is used to detect changes in the structure of the DOM tree of the page.

[0069] In another possible implementation, the client detects the Uniform Resource Locator (URL) of the displayed page. When it is detected that the URL of the page has changed, it is determined that the page has jumped and the page elements of the page have changed. Alternatively, the client detects the user's operation. If it is detected that the user has triggered an operation on the page element, it is determined that the page element of the page has changed.

[0070] When the client detects changes in page elements, it determines the white screen score of the currently displayed page. This enables a more comprehensive white screen detection and determines the white screen that appears during the page operation.

[0071] The currently displayed page is the page displayed after the page elements are changed. The white screen score of the page is used to measure the complexity of the page elements included in the page.

[0072] See also Figure 3 As shown, it is determined whether the white screen score meets the initial judgment condition. If the white screen score meets the initial judgment condition, it means that there is a possibility that the page is a white screen, and it is necessary to further determine whether the page is a white screen. If the white screen score does not meet the initial judgment condition, it means that the page is not a white screen, and the white screen detection of the page is ended.

[0073] The initial judgment condition is a pre-set condition for judging whether a page is a white screen using a white screen score. As an example, the initial judgment condition is that the white screen score is less than or equal to the score threshold. The score threshold can be pre-set based on the business services provided by the page. If the white screen score is less than or equal to the score threshold, it means that the page elements included in the page are relatively simple, and there is a possibility that the page is a white screen, and it is necessary to continue to judge whether the page is a white screen.

[0074] The embodiment of the present application does not limit the implementation method of determining the white screen score of the page.

[0075] As an example, the white screen score of the page is determined using the DOM tree of the page.

[0076] The DOM tree includes multiple DOM nodes. Each DOM node corresponds to a page element included in the page. The node score of the DOM node is determined based on the number of layers of the DOM node in the DOM tree and the display ratio of the DOM node. The number of layers of the DOM node in the DOM tree can reflect the complexity of the DOM tree, that is, the complexity of the hierarchical relationship between the page elements. The display ratio of the DOM node is the ratio of the display area of ​​the page element corresponding to the DOM node in the page to the display area of ​​the page element corresponding to the parent node of the DOM node in the page. The display ratio of the DOM node can reflect the display ratio of the page element corresponding to the DOM node in the page.

[0077] As an example, the node score of a DOM node is calculated by formula (1):

[0078]

[0079] Where depth is the number of layers of the DOM node in the DOM tree. height is the display height of the page element corresponding to the DOM node. innerheight is the display height of the page element corresponding to the parent node of the DOM node. width is the display width of the page element corresponding to the DOM node. innerwidth is the display width of the page element corresponding to the parent node of the DOM node.

[0080] The obtained node score of the DOM node is used to determine the white screen score, which is, for example, a statistical value of the node score of the DOM node.

[0081] As an example, the white screen score is the sum of the node scores of the DOM nodes.

[0082] In one possible calculation method, the node score of each DOM node included in the DOM tree is calculated respectively. Then the sum of the node scores of each DOM node is calculated to obtain the white screen score. As an example, a breadth first search method is adopted to traverse each DOM node to determine the node score of each DOM node.

[0083] Another possible calculation method is that the node score of the DOM node is not a negative number. The initial judgment condition is that the white screen score is less than or equal to the score threshold.

[0084] After obtaining the node score of a DOM node each time, the sum of the node scores of the determined DOM nodes is calculated to obtain the intermediate score. Determine whether the intermediate score meets the initial judgment condition. If the intermediate score no longer meets the initial judgment condition, the sum of the node scores of all DOM nodes also does not meet the initial judgment condition, and there is no need to continue calculating the node scores of other DOM nodes. Use the intermediate score as the white screen score. If the intermediate score meets the initial judgment condition, continue to calculate the node scores of the DOM nodes and update the intermediate score until all DOM nodes included in the DOM tree are calculated, or the intermediate score does not meet the initial judgment condition.

[0085] The following is a possible implementation method for calculating the white screen score, including A1-A2:

[0086] A1: Among the DOM nodes included in the DOM tree, the DOM node that is ranked first in a preset order is used as the target DOM node.

[0087] The preset order is the order in which the DOM nodes are calculated. As an example, the preset order is from top to bottom and from left to right. The target DOM node is the DOM node for which the node score is calculated this time.

[0088] A2: Loop the following operations until the next DOM node of the target DOM node indicated by the preset order is empty, or the middle score does not meet the initial judgment condition, and use the middle score as the white screen score:

[0089] Determine the node score of the target DOM node;

[0090] Determine an intermediate score based on the node scores of the DOM nodes included in the determined DOM tree;

[0091] The next DOM node of the target DOM node indicated by the preset sequence is used as the target DOM node.

[0092] In this way, when the intermediate score does not meet the initial judgment condition, the calculation of the node score of the DOM node can be ended, thereby saving computing resources for calculating the node score and improving the speed of calculating the white screen score.

[0093] S202: If the white screen score meets the initial judgment condition, the client sends page information of the page to the server.

[0094] When the white screen score meets the initial judgment condition, the server needs to judge whether the page is a white screen again to obtain the final judgment result of whether the page is a white screen.

[0095] In some possible implementations, after determining that the white screen score meets the initial judgment condition, before the client sends the page information of the page to the server, it is also determined that the page is not a preset security page. The preset security page is a page that is determined not to be a white screen. As an example, a page whitelist is pre-established. The page whitelist includes preset security pages.

[0096] The embodiment of the present application does not limit the implementation method of determining that a page is not a preset security page. As an example, a filtering HTML tag for a security page is preset. Figure 3 As shown, it is determined whether the DOM of the page includes a filter HTML tag. If the DOM of the page does not include a filter HTML tag, it means that the page is not a safe page and there is a possibility of a white screen. The filter HTML tag is, for example, an interactive HTML tag or a custom HTML tag. The interactive HTML tag is, for example, <textarea>< / textarea> Label or <input> If the DOM of the page includes the filtered HTML tag, it means that the page is a safe page and the page is not a white screen, and the white screen detection of the page ends.

[0097] The client obtains the page information of the page. The page information is used to determine whether the page is a white screen.

[0098] As an example, the page information of a page includes a page image obtained by taking a screenshot of the page. Figure 3 As shown, the client takes a screenshot of the page to obtain a page image. For example, the client calls HTML2Canvas to convert the DOM nodes included in the DOM tree corresponding to the page into an image to obtain the page image.

[0099] As another example, the DOM nodes included in the DOM tree corresponding to the page are relatively complex. If the client takes a screenshot of the page, it will affect the normal operation of the client main thread.

[0100] The client obtains the HTML string of the page and sends the page information including the HTML string of the page to the server. The HTML string is used to render the page. The server can render the page based on the obtained HTML string. This can reduce the cost of white screen detection on the client.

[0101] As an example, an HTML string is a string obtained by concatenating the string corresponding to the DOM node of the page and the style tag string, and deleting the script tag. The string corresponding to the DOM node is used to determine the page elements included in the page. The style tag is used to define the style of the page element. The script tag is used to define the client script. Deleting the script tag can improve the stability of the server when rendering the page using the HTML string.

[0102] In addition, after generating the HTML string of the page, you can also compress the HTML string. For example, compress the HTML string using zip (a compression method) to obtain a binary file. Figure 3 As shown, the client sends a compressed HTML string, that is, a binary file, to the server. As an example, the main thread of the client generates an HTML string and sends the HTML string to the Web Worker through IPC (Inter-Process Communication). WebWorker implements the compression of the HTML string. Web Worker is an independent thread running on the client except the main thread. In this way, the resource occupation of the client main thread by white screen detection can be reduced, the impact of white screen detection on the client display page can be reduced, the efficiency of the client display page can be improved, and the jamming of the display page can be reduced.

[0103] After obtaining the page information of the page, the server determines whether the page is a blank screen based on the page information of the page. As a possible implementation method, the embodiment of the present application provides an implementation method for the server to use the page information of the page to determine whether the page is a blank screen, including the following steps:

[0104] B1: The server obtains the page information sent by the client.

[0105] B2: The server obtains the page image of the page based on the page information.

[0106] The server parses the page information and obtains the page image of the page.

[0107] In a possible implementation, the page information includes a page image, and the server parses the page information to obtain the page image.

[0108] In another possible implementation, the page information includes an HTML string of the page. The server parses the page information to obtain the HTML string. For example, in the case where the page information includes a binary file obtained by compressing the HTML string, see Figure 3As shown, the server can decompress the binary file to obtain an HTML string. The client can use Decompressor (a decompression tool) to decompress the binary file. The server renders the page based on the HTML string and takes a screenshot of the page to obtain a page image. As an example, the server calls puppeteer (a browser without a graphical user interface) to process the HTML string and render the page.

[0109] B3: The server uses the white screen detection model to process the page image and obtain the white screen detection result.

[0110] The white screen detection model is a pre-trained model used to determine the white screen detection result based on the input page image. The white screen detection model is, for example, a deep learning model.

[0111] The server inputs the page image into the white screen detection model and obtains the white screen detection result output by the white screen detection model. The white screen detection result is used to indicate whether the page image is a white screen image. As an example, the white screen detection result is a probability value that the page image is a white screen image. As another example, the white screen detection result is a determination value of whether the page image is a white screen image. The type of the white screen detection result is determined by the training process of the white screen detection model.

[0112] In a possible implementation, the server needs to normalize the image size of the page image before inputting it into the white screen detection model. The processed page image meets the size requirements of the image processed by the white screen detection model and adapts to the size of the input image that the white screen detection model can process.

[0113] As an example, an embodiment of the present application provides a training method for a white screen detection model, including the following steps C1-C2:

[0114] C1: Obtain a training page image and a label corresponding to the training page image. The training page image is a white screen image or a non-white screen image. The label is used to identify whether the training page image is a white screen image.

[0115] A training data set for training a white screen detection model is pre-established. The training data set includes training page images and labels corresponding to the training page images.

[0116] The training page image is a white screen image or a non-white screen image. The training page image included in the training data set is an original white screen image, or an original non-white screen image, and is also, for example, a page image obtained by performing an enhancement operation on the original white screen image or the original non-white screen image. The enhancement operation, for example, includes operations such as inversion and rotation to expand the training page image included in the training data set.

[0117] The label corresponding to the training page image is used to identify whether the training page image is a white screen image. As an example, when the label corresponding to the training page image is 0, it means that the training page image is not a white screen image. When the label corresponding to the training page image is 1, it means that the training page image is a white screen image.

[0118] C2: The white screen detection model is trained using the training page images and the labels corresponding to the training page images.

[0119] The embodiment of the present application does not limit the method of training the white screen detection model using training page images and labels corresponding to the training page images.

[0120] In one possible implementation, the white screen detection model is pre-trained using imageNET (image network). Then, the white screen detection model is trained using the training page images and the labels corresponding to the training page images, and the pre-trained white screen detection model is fine-tuned (Finetune). This can increase the speed of training the white screen detection model and improve the efficiency of training the white screen detection model.

[0121] B4: The server determines whether the page is a white screen based on the white screen detection result.

[0122] As an example, the white screen detection result is used to measure the possibility that the page image is a white screen image. For example, the white screen detection result is a probability value that the page image is a white screen image. The server determines whether the white screen detection result belongs to the numerical interval of the white screen image. If the white screen detection result belongs to the numerical interval of the white screen image, it is determined that the page is a white screen. If the white screen detection result does not belong to the numerical interval of the white screen image, it is determined that the page is not a white screen.

[0123] As another example, the white screen detection result is a determination value of whether the page image is a white screen image. The server can determine whether the page is a white screen according to the determination value.

[0124] In a possible implementation, when the server determines that the page is a white screen, the server calls a white screen processing method to process the page.

[0125] Based on the above content, it can be known that in the white screen detection method provided in the embodiment of the present application, comprehensive detection of the page can be achieved. In addition, the client performs initial white screen detection on the page, which can reduce the resources consumed by the client to detect the white screen and reduce the cost of the client to detect the white screen. The client and the server perform white screen detection on the page in turn, which can improve the confidence of the white screen detection and reduce the false alarm rate of the white screen detection.

[0126] Based on a white screen detection method provided in the above method embodiment, an embodiment of the present application further provides a white screen detection device, which will be described below in conjunction with the accompanying drawings.
