Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application.
In the present application, the terms "first," "second," and "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated unless otherwise explicitly specified and defined. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, unless explicitly specified otherwise. The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
It should be noted that, the data recording method based on the web page of the present application may be implemented based on a software program, so that the method may be executed on a server or a computer, and the specific use scenario of the method is not limited, as long as the scenario can implement the data recording method based on the web page of the present application.
Fig. 1 is a flowchart of a data recording method based on a web page according to an embodiment of the present application; as shown in fig. 1, the method includes:
step 101: and responding to the task opening instruction, and downloading and acquiring the webpage codes of the graphical interface of the current webpage based on the preset browser.
It should be noted that, in one possible implementation manner, the task opening instruction may be issued by the user according to the use requirement, that is, the task opening instruction is issued by, for example, operating a control, a case, or an input instruction of the related device, which is not limited herein.
It should be noted that, the issuing of the task start instruction may also be implemented based on a software program. In one possible implementation, the task start instruction is a running start instruction of the software program, that is, the task is started after the software starts to run, that is, the method steps in step 101 are started to be executed.
In another possible implementation, the task start instruction is different from the running start instruction of the software program, and in this implementation, after the software program receives the running start instruction, the software program starts to run and waits for the task start instruction; the method steps in step 101 are performed beginning after the task opening instruction is captured.
It should be noted that, the task start instruction may be an instruction set according to time, for example, the task start instruction is sent at a specific time in a timing setting, so that the software program executes the subsequent steps. For example, if the task start command is set to be sent at 01:00:00 pm every day, the method of the application can respond after the task start command is captured at the time. The task opening instruction can also be a trigger condition, namely, after the set condition is met, the task opening instruction is sent, so that the software program starts to operate, and the subsequent steps are executed. For example, after capturing the task opening instruction after opening the specific webpage, the method of the present application may respond after capturing the task opening instruction after opening the specific webpage.
The above is merely an example, and in practical use, other manners of issuing the task start instruction and other forms of task start instruction are possible, which is not limited by the present application.
And after receiving the task opening instruction, downloading and acquiring the webpage code of the graphical interface of the current webpage based on the preset browser.
The application is not limited to the operating system on which the data recording method based on the webpage is based, in a possible implementation manner, the data recording method based on the webpage of the application can be realized based on a Linux (GNU/Linux) system, the above is only an example, in a specific implementation process, other types of operating systems can be selected, the operating systems can compile/support a preset browser, for example, a browser supporting DevTools Protocol, and the application is not limited to the specific operating system type.
The application does not limit the specific type of the preset browser, as long as the browser can be developed for the second time, and in a specific implementation mode, the preset browser can be an open-source chrome browser.
Downloading the web page code to obtain the graphical interface of the current web page may take many forms, for example, in a specific implementation, the chrome browser is set to the handle mode by using an open-source chrome browser, and after the web page is opened (i.e. the web site address is opened, or the uniform resource locator system (uniform resource locator, URL) is opened), the code of the current web page is downloaded.
It should be noted that, the downloading of the code of the current webpage may be downloading all the codes of the current webpage, executing the codes, and obtaining some operation information therein; the downloading of the code of the current webpage may be that after all the webpage codes of the current webpage are downloaded, a preset code is injected into the webpage codes, and the logic of the webpage codes is checked or the recording time is marked. The logic verification of the webpage codes refers to that the preset codes are injected into the downloaded webpage codes, and the logic of the webpage codes is judged according to the feedback or running condition of the webpage so as to evaluate the stability, the safety and the like of the webpage codes. Recording the mark-up time to the web page refers to marking the current recording time with a watermark or other form on the recorded video while recording.
The foregoing is merely an example, and in practical implementation, the code for downloading the current webpage may be other downloaded forms, which is not limited in the present application, so long as the webpage code of the graphical interface of the current webpage is obtained and the preset function operation is implemented.
It should be noted that, if the operation to be performed on the graphical interface of the current page is recorded, the operation may also be performed by replacing the web page code, that is, in response to the task opening instruction, the new replacement data replace the source code data in the web page code of the current web page corresponding to the web page code, so that the web page code of the new graphical interface of the current web page corresponding to the replaced web page code may be invoked, thereby implementing the recording of the web page operation. The new replacement data may be new replacement data input by the user after the task is started, or may be new replacement data stored in advance. The operation effects of clicking, selecting and the like on the current webpage can be achieved by using a mode of replacing codes, and the operation effects are the same as those achieved by a user through the peripheral. The foregoing is merely an example, and other manners of obtaining the operation on the code layer may be provided, which are not limited in this aspect of the present application, and the operation on the graphical interface of the current page may be implemented.
In a specific implementation manner, the replacement data of the code corresponding to the specific position selection operation is prestored in the target webpage, and when the target webpage is detected to be the target webpage of the prestored new replacement data in response to the task opening instruction, the source code data in the webpage code of the corresponding current webpage in the webpage codes is replaced according to the new replacement data, and the response corresponding to the current webpage can be obtained by calling the replaced webpage code, so that the response in the code form of the selection operation is obtained.
The application does not limit the specific content contained in the page code of the graphical interface, and the code related to the presentation mode and effect of the graphical interface belongs to the range of the page code of the graphical interface. In practical application, the content contained in the page code of the graphical interface can be flexibly set according to practical use and recording requirements.
Step 102: and converting and acquiring current interface data in a preset format according to the webpage codes.
It should be noted that the application can finally record the data of the web page and then synthesize the video, and transmit the video to the terminal for display, and the different terminals have different requirements on the format, resolution, frequency, code rate and the like of the video. Thus, when responding to the task opening instruction, the current interface data in the preset format can be obtained, wherein the preset format comprises, but is not limited to, preset resolution, preset frame rate, preset code rate and the like. In the present application, the codes are downloaded and acquired in step 101 and step 102, so that the current interface refers to the interface encoded data.
It should also be noted that the preset format may be set by a developer in a software program, for example, classifying common web pages: setting different preset formats for the video type web page, the image type web page and the text type web page in comparison with the same type web page, and acquiring the preset formats of the web page by acquiring the classification of the web page after responding to the task opening instruction; the preset format may also be manually set by the developer when issuing a task open command. The foregoing is merely an example, and in a specific implementation process, other manners may be used to set the preset format, for example, a default value meeting most of the use needs may be set, and after the corresponding task is started, the default value is the preset format of the web page, which is not limited in the present application.
In one possible implementation, the current web page is a video type web page, and the preset format set by the developer is: the preset resolution is a x b pixel, the preset frame rate is cHz, the preset code rate is dbit/s, the format of the current interface data obtained through conversion is a x b pixel, the frame rate is cHz, and the code rate is d bit/s (a, b, c, d is larger than 0). For example, in a specific implementation, the current web page is a video type web page, and the preset format set by the developer is: the preset resolution is 1280 x 720 pixels, the preset frame rate is 10Hz, and the preset code rate is 1Mbit/s. The format of the current interface data obtained by conversion is 1280 x 720 pixels in resolution, 10Hz in frame rate and 1Mbit/s in code rate.
Step 103: and storing the current interface data in a preset format into a memory.
And storing the current interface data in the preset format obtained in the step 102 into a memory for subsequent calling.
In summary, an embodiment of the present application provides a data recording method based on a web page, including: responding to a task opening instruction, and downloading and acquiring a webpage code of a graphical interface of a current webpage based on a preset browser; according to the webpage codes, converting to obtain current interface data in a preset format; and storing the current interface data in a preset format into a memory. Compared with the prior art of recording web pages based on a graphical interface, the method has the advantages that on one hand, the consumption of the codes to a CPU and a memory is less, smooth and efficient data transmission is facilitated, and the software program is stably operated; the operation can be realized by utilizing codes, so that the webpage recording based on the image interface can be automatically operated without manual duty. On the other hand, the format of the obtained current interface data meets the requirement of a preset format, so that the current interface data can be used without denoising, rendering, processing and the like, and the requirement of recording webpage data of diversified users can be met.
Optionally, on the basis of fig. 1, the present application further provides a possible implementation manner of a data recording method based on a web page, and fig. 2 is a flowchart of a data recording method based on a web page according to another embodiment of the present application; as shown in fig. 2, after storing the current interface data in the preset format into the memory, the method includes:
step 201: extracting current interface data from the memory at a preset frequency;
for the current interface data stored in the memory in step 103, the secondary development tool may be used to extract the current interface data according to the preset frequency when the current interface data needs to be synthesized. It should be noted that, the preset frequency may be set in a software program by a developer, and after responding to a task opening instruction (step 101), the preset frequency of the web page is obtained; the preset frequency can also be set manually by a developer when a task opening instruction is issued. The foregoing is merely an example, and in a specific implementation process, there may be other ways to set the preset frequency, for example, a default value meeting most of the use needs may be set, and after a corresponding task opening instruction, the default value is the preset frequency of the web page, which is not limited in the present application.
For example, assuming the preset frequency is 25 frames/second from default, steps 201 and 202 are accomplished using the open source chrome browser and the secondary development tool browser development suite (Chrome DevTools Protocol). The decimation is performed at a preset frequency of 25 frames/second using Chrome DevTools Protocol.
Step 202: and synthesizing the video file to be transmitted according to the extracted current interface data.
The current interface data extracted in step 201 is synthesized into a video file to be transmitted, and it should be noted that, in a specific implementation manner, the preset format in step 102 further includes an image generating manner for the extracted current interface data to generate an image in the target format. For example, in the preset format, the image generation mode of the current interface data is a JPEG format, which means that the current interface data needs to be subjected to lossy compression, and a picture in the JPEG format meeting the requirement of the preset resolution is generated after redundant image data is removed. Similarly, according to the actual use requirement, the image generation mode of the current interface data can be PNG format, TIF format, etc., which is not limited by the present application.
Extracting the current interface data from the memory at a preset frequency, and generating an image with a corresponding format according to the extracted current interface data according to a set image generation mode of the extracted current interface data. And secondly, video synthesis is carried out on the generated images with the corresponding formats according to the extraction sequence and the preset frequency, so that a video file to be transmitted is obtained.
In a specific implementation manner, the image generation mode of the current interface data in the preset format is a JPEG format, the preset frequency is 25 times/second, and the secondary development tool Chrome DevTools Protocol is used for generating a picture in the JPEG format, which meets the requirement of the preset resolution, on the extracted current interface data. And secondly, video synthesis is carried out on the generated images with the corresponding formats according to the extraction sequence and the frequency of 25 pieces/second, so as to obtain the video file to be transmitted.
The conversion from the code to the video of the current webpage recording is realized by extracting the current interface data from the memory and then synthesizing the video file with transmission, the conversion mode is simple, the frame rate can be set and adjusted according to the use requirement of a user, and the method has high flexibility.
Optionally, on the basis of fig. 2, the present application further provides a possible implementation manner of a data recording method based on a web page, and fig. 3 is a flowchart of a data recording method based on a web page according to another embodiment of the present application; in some embodiments, the recorded object includes a sound source, that is, some audio content, as shown in fig. 3, the method includes:
step 301: responding to a task opening instruction, and acquiring a sound source corresponding to a current webpage;
it should be noted that, after responding to the task opening instruction, there may be various ways to obtain the audio source corresponding to the current web page. In one possible implementation manner, the manner of acquiring the sound sources corresponding to the current webpage may be that the operating system automatically performs identification and acquisition, for example, N sound sources (N > 0) are in the operating system, after a task opening instruction, the state of M sound sources (n+.m0) is changed (from an inactive state to an active state), and then the operating system identifies the M sound sources as the sound sources corresponding to the current webpage.
In another possible implementation manner, the method of acquiring the sound source corresponding to the current webpage may be to manually input the number of the sound source corresponding to the current webpage, where each sound source has a unique number in the operating system, and the user may manually input the number to acquire the information of the sound source.
In another possible implementation manner, the manner of acquiring the sound source corresponding to the current webpage may be a default sound source, that is, one or a plurality of default sound sources are set in the operating system, and the plurality of sound sources are acquired as the sound source corresponding to the current webpage in response to the task opening instruction. In another possible implementation manner, the manner of acquiring the sound source corresponding to the current webpage may be controlled through a webpage interface, and the sound source expected by the user is selected.
The above is merely an example, and the specific implementation manner of obtaining the sound source corresponding to the current webpage is not limited in the present application, and the obtaining of the sound source corresponding to the current webpage may be achieved.
In one specific implementation, a Ubuntu operating system is used that, in response to a task start instruction, obtains sound source information from a browser and an audio console (pulseaudio), determines the source of the sound source information, and confirms the sound source corresponding to the current web page therefrom.
Step 302: if the number of the sound sources is one, sound data of the sound sources are acquired.
After judging the sound source corresponding to the current webpage, the operating system acquires the sound data of the sound source if only one corresponding sound source exists.
In one specific implementation, the Ubuntu operating system confirms that there is only one corresponding sound source and transmits the sound data of that sound source to an audio console (pulseaudio).
By acquiring the sound source corresponding to the current page, the recording of the audio data in the webpage data recording is realized, wherein the sound source can be automatically identified through the system, so that the webpage-based data recording method is more intelligent and more convenient.
Optionally, on the basis of fig. 3, the present application further provides a possible implementation manner of a data recording method based on a web page, where the method includes:
if the number of the sound sources is a plurality of, mixing the sound of the plurality of sound sources to obtain mixed sound data.
It should be noted that, if the sound data corresponding to the current web page is stereo, there are two sound sources generally; if the sound data corresponding to the current webpage is 5.1 sound, five sound sources are usually available; i.e. the number of sound sources is different for different sound data types. After judging the sound sources corresponding to the current webpage, the operating system determines the number of the sound sources corresponding to the webpage and specific sound source numbers, then the operating system calls an interface of an audio console through software to realize sound mixing, and sound data after sound mixing is obtained.
In a specific implementation manner, after confirming that five corresponding sound sources exist in the Ubuntu operating system, calling an interface of the audio console through software, transmitting sound data of the five sound sources to the audio console (pulseaudio), and performing mixing processing on the sound data of the five sound sources by the audio console.
When the number of the sound sources is multiple, sound of the multiple sound sources is mixed, sound data after sound mixing is obtained, and quality of sound data corresponding to the current webpage is guaranteed.
Optionally, on the basis of the foregoing embodiment and fig. 3, the present application further provides a possible implementation manner of a data recording method based on a web page, where the method includes: and synthesizing a new video file to be transmitted according to the video file to be transmitted and the sound data.
And synthesizing the video file to be transmitted and the sound data acquired in the subsequent steps through the step 202, and synthesizing to obtain a new video file to be transmitted. The video file to be transmitted obtained in step 202 essentially comprises a plurality of picture files and a predetermined frequency. In one possible implementation, when the video file to be transmitted and the sound data are synthesized, the audio/video portability can be performed by using a software program, for example, the playing time of the video file to be transmitted and the playing time of the sound data are aligned. The foregoing is merely illustrative, and in practical implementation, other synthesis manners may be available, and the present application is not limited to a specific synthesis manner, and may be capable of implementing synthesis of a video file and sound data to be transmitted.
