- a computer-readable storage medium on which a computer program is stored, and when the program is executed by a processor, the method shown in the first aspect of the present disclosure is implemented.
- the query request for the image in the web page is sent to obtain the query result of the query request, and based on the query result, it is determined whether the image is loaded successfully. Based on this solution, the information about whether the image is loaded successfully can be obtained by initiating an image query request, thereby realizing the monitoring of whether the image is loaded successfully, and realizing the analysis of the web service quality based on whether the image is loaded successfully, and improving the web service quality Provide data support.
- FIG. 1 is a schematic flowchart of a method for monitoring webpage images according to an embodiment of the disclosure
- FIG. 2 is a schematic structural diagram of a webpage image monitoring device provided by an embodiment of the disclosure.
- FIG. 3 is a schematic structural diagram of an electronic device provided by an embodiment of the disclosure.
- a software development kit (Software Development Kit, SDK) is generally used to monitor whether an image in a web page is successfully loaded.
- SDK Software Development Kit
- the business party may place the SDK corresponding code for monitoring whether the image is loaded successfully in the body of the HyperText Markup Language (HTML) file of the web page.
- HTML HyperText Markup Language
- this may cause the SDK to monitor whether the image has been successfully loaded is still not running when the image loading has been completed. At this time, it cannot be obtained that the SDK has been loaded before the above SDK runs. Whether the image of the completed image is loaded successfully, resulting in the omission of information monitoring, and it is impossible to effectively monitor whether the image in the web page is loaded successfully.
- the webpage image monitoring method, device, electronic device, and computer-readable storage medium provided by the embodiments of the present disclosure are intended to solve at least one of the above technical problems in the prior art.
- FIG. 1 shows a schematic flowchart of a method for monitoring webpage images provided by an embodiment of the present disclosure. As shown in FIG. 1, the method may include:
- Step S110 When it is detected that all page resources of the web page have been loaded, sending a query request for the image in the web page;
- Step S120 Obtain the query result of the query request, and determine whether the image is loaded successfully based on the query result.
- a browser loads a web page as an example.
- the page resources may include, but are not limited to, characters, image resources, video resources, etc. in the web page.
- a query request can be generated to query the image resource corresponding to each image in the web page, and the query request can carry an image identifier, which is convenient for distinguishing each image in the web page.
- the image resource of the web page is successfully loaded, the image resource of the web page is cached in the browser cache, and the query result is determined based on the cache content in the browser cache.
- the browser When the browser is loading, it encounters the page resource that needs to be obtained (take picture resource as an example), the browser may issue a picture resource acquisition request to obtain the picture resource, when the picture resource request is successful, the obtained picture resource will be cached To the browser cache; when the image resource request fails, the image resource will not be stored in the browser cache. Therefore, it is possible to determine whether the image is loaded successfully by sending a query request and querying the image resource in the browser cache. When the image resource corresponding to the image is found in the browser cache, it can be determined that the image is loaded successfully; if the image resource corresponding to the image is not found in the browser cache, it can be determined that the image has failed to load.
- the query result can be obtained quickly, without the need to request data from the server through the network, which can avoid traffic waste.
- the image query request is sent when it is detected that all images in the web page have been loaded. Since all image resources have been loaded at this time, it can be ensured that the query results of all query requests are obtained, thereby monitoring the page Whether all the images inside are loaded successfully, to avoid monitoring omissions.
- the browser will load each page resource separately. In the process of loading the page resource, the page resource takes the image as an example. It may happen that some images have finished loading while others have not finished loading. , The image resources corresponding to the images that have not been loaded will not be stored in the local cache. At this time, if the corresponding image is queried in the local cache, the query results will be inaccurate and it is impossible to effectively determine whether the image is loaded successfully.
- sending a query request for the image in the web page can ensure the accuracy of the obtained query result, so that it can accurately determine whether the image in the web page is loaded successfully.
- these images can be analyzed to determine the cause of the load failure, and corresponding processing can be performed to ensure the user experience.
- the method provided by the embodiment of the present disclosure is to send a query request for the image in the web page when all page resources of the web page are loaded to obtain the query result of the query request, and determine whether the image is loaded successfully based on the query result. Based on this solution, the information about whether the image is loaded successfully can be obtained by initiating an image query request, thereby realizing the monitoring of whether the image is loaded successfully, and realizing the analysis of the web service quality based on whether the image is loaded successfully, and improving the web service quality Provide data support.
- the query request is an Extensible Markup Language Hypertext Transfer Protocol request (XML HTTP Request).
- XML HTTP Request Extensible Markup Language Hypertext Transfer Protocol request
- the query request may be an XML HTTP Request, and the query request may also carry request parameters corresponding to the attribute information of the image, and the attribute information may include the image type and/or the image size.
- the above method may further include: extracting attribute information of the image based on the query result.
- the query result is the response information of the query command.
- the response header of the response message contains the attribute information of the image.
- the image attribute information of the image can be extracted from the response header in the response message through regular expressions.
- the monitoring of image attribute information can better analyze the service quality of the webpage through the monitored image attribute information, and provide better data support for improving the service quality of the webpage.
- the query request also carries file location indication information of the image.
- request parameters can also be set in the query request to specify the file location to be queried. For example, when querying images imported from Cascading Style Sheets (CSS) files, you can specify Query in the Style Sheets cached by the browser.
- CSS Cascading Style Sheets
- the foregoing method further includes:
- the onload event corresponding to the HTML file of the web page when all the page resources of the web page are loaded, the onload event corresponding to the HTML file of the web page will be executed.
- the onload event corresponding to the HTML file of the web page can be detected to determine all of the web page. Whether the page resource has been loaded.
- the above method further includes:
- the information about whether the image is loaded successfully can be sent to the server, so that the server can monitor whether the image is successfully loaded in time. In actual use, you can also choose to only upload the image.
- the loading failure information is sent to the server.
- FIG. 2 shows a schematic structural diagram of a webpage image monitoring device provided by an embodiment of the present disclosure.
