Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below. The technical features of the embodiments of the invention can be combined correspondingly on the premise of no mutual conflict.
In the description of the present invention, it will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be indirectly connected with intervening elements present. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.
In the description of the present invention, it should be understood that the terms "first" and "second" are used solely for the purpose of distinguishing between the descriptions and not necessarily for the purpose of indicating or implying a relative importance or implicitly indicating the number of features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.
As shown in fig. 1, in the embodiment of the present invention, a rich text copying method at a browser end based on cloud service is provided, where the method can copy rich text contents containing a large number of multimedia files in carriers such as WORD and PPT at a local end, and paste the rich text contents into a rich text editing page of a web application at the browser end in batches, so as to solve the problem that the web application cannot read the local file and cannot copy the rich text contents in batches due to browser limitation. The specific implementation method of the cloud service-based browser-side rich text copying method is described in detail below in combination with the steps S1-S3.
S1, registering a monitoring event on a rich text editing page of a browser end, and acquiring paste content information from a system paste board when a user is monitored to execute paste operation in a rich text editor.
It should be noted that, the manner of obtaining the paste content information from the system paste board belongs to the prior art, and will not be described again. The copy source of the rich text content in the invention can be local WORD, PPT and other files, and can be theoretically web page content without limitation.
In addition, in order to facilitate the use of the common user, the browser end monitors the registration of the event, and the realization can be realized by installing a special client end on the local end by the user. Of course, the client may not necessarily only realize the single function of registering the monitoring event, and the functions of analyzing data, processing file byte stream, uploading the server, packaging the HTML file and the like in the subsequent steps may also be uniformly realized by the client. When a user opens an editing page of the rich text editor to edit contents, the client can establish a communication relationship with a locally established monitoring service by using a WebSocket immediately after the user opens the current editing page, and if the connection is successful, the installed client of the user is prompted to enter a monitoring state, and the monitoring event comprises message receiving, communication channel closing and communication failure.
S2, analyzing the paste content information obtained in the S1, respectively extracting text content and all multimedia files from the text content, respectively generating abstract information of each multimedia file, checking whether each multimedia file is uploaded through a request cloud server interface, directly acquiring a network resource address of the multimedia file on a cloud server if one multimedia file is uploaded, and calling certificates required by a cloud storage service to upload the multimedia file to the cloud server and then acquiring the network resource address of the multimedia file if the multimedia file is not uploaded.
It should be noted that, when the rich text content is copied from different carriers, the format of the paste content information may be different, so that the specific manner of parsing the paste content information needs to be adjusted according to the actual format of the paste content information. The pictures and the videos are the most common multimedia files, so in the embodiment of the invention, when the pasted content information is analyzed, analysis and verification rules of the pictures and the videos can be respectively set.
For pictures, they are typically created and recorded with a local protocol file address when copied. Therefore, in the embodiment of the invention, when the paste content information is analyzed, whether a multimedia file in a picture form (the format of the picture includes, but is not limited to png, tif, jpg and the like) exists or not can be matched through a regular expression, if the picture exists, the picture byte data is obtained through the local protocol file address of the picture existing in the paste content information, and then the abstract information of the picture is generated and sent to the cloud server interface for verification.
For example, when copying the rich text content of the picture contained in the local word file to the web application, the obtained paste content information in the paste event in the system paste board is generally in HTML format, the read HTML content can be transmitted to the local client through the websocket communication technology, the client analyzes the HTML text, including the HTML tag and url address, and the picture temporary path is identified through the regular expression so as to obtain the picture file, so that the picture file is conveniently sent to the cloud server.
For video, a compressed ole file is generally generated when the video is copied, and the ole file is decompressed to obtain a file named "[ 1] ole10 native", in which path information in the video byte file and byte data of the source video are recorded. Therefore, in the embodiment of the invention, when the paste content information in the system paste board is analyzed, whether the ole file exists can be judged, if so, the multimedia file byte data in the form of video is extracted from the ole file, meanwhile, the position of each video in the original paste content information is determined, and then the abstract information of the video is generated and sent to the cloud server interface for verification.
An important function of the cloud server in the invention is to store mass multimedia files in rich texts, and in a scene where a large number of users access, the cloud server can use object storage services (oss) to store files, thereby meeting the requirements of mass storage and security of uploading files by platform users and having elastic expansion capability.
In the invention, the fingerprint calculation is designed for the file byte stream and binding with the uploading record so as to improve the pasting performance and reduce the file repeated uploading space waste, thereby being capable of carrying out uploading uniqueness judgment by considering the repeatability and redundancy of a large number of multimedia files during storage. Specifically, summary information of each multimedia file needs to be generated in advance, and then whether each multimedia file is uploaded or not is checked by requesting a cloud server interface. In specific implementation, the summary information of each file can be obtained through a summary calculation function, and the summary information can be generated by using MD4, MD5, SHA1, SM3, and the like.
In addition, considering that large files such as pictures and videos are easy to fail in uploading due to unstable networks and the like, the picture byte streams of the large files can be uploaded in a piece by piece in the process of uploading the multimedia files to the cloud server, and the support of breakpoint continuous transmission can be considered. In the embodiment of the invention, when the multimedia file is uploaded to the cloud server, whether the size of the multimedia file exceeds a threshold value is needed to be judged, if so, the multimedia file is required to be fragmented, then whether each fragment of fragment data is uploaded is checked, and if not, the corresponding fragment sequence number and fragment data are uploaded to the server.
It should be noted that, if a multimedia file has not yet been uploaded to the cloud server, it needs to invoke credentials required by the cloud storage service to verify, and the verification may upload the multimedia file to the cloud server to generate its network resource address through the back. Similarly, when the abstract information of the multimedia file is sent to the cloud server interface for verification, if the cloud server requires verification, a data acquisition credential is required to be provided to ensure the safety of cloud data.
In addition, because the invention is a batch of rich text content copying method, if the number of multimedia files to be uploaded to the cloud server is large, the time required for uploading the checksum of the multimedia files can be longer. Therefore, in consideration of user experience, the uploading return state of each multimedia file can be received in real time in the process of uploading the multimedia files to the server, and is transmitted to the browser through the websocket communication technology, and visual display is carried out on the browser section through the progress bar, so that the user can see the whole uploading progress.
S3, replacing the local file by using the network resource address of the multimedia file, and pasting the analyzed text content and the network resource address of each multimedia file into an HTML file and then into a rich text editing page.
In the invention, the original copied local multimedia files are uploaded to the cloud server in the previous step, so that the network resource addresses of the multimedia files can be used for replacing the local multimedia files in the original system paste board, and the analyzed text content and the network resource addresses of the multimedia files are combined into the HTML file again, so that rich text can be directly displayed in the web application of the browser side. In the process, the local client can automatically process the processes of analysis, file acquisition, uploading, network address replacement and the like in the background, so that users do not need to process one by one, and the problem that web applications cannot read local files and further cannot copy rich text contents in batches due to browser limitation is solved.
For multimedia files such as most common pictures and videos, the manner in which the multimedia files are combined to form the HTML file needs to consider the respective positions of the multimedia files in the original file. For example, for the pictures, after the network resource address of each picture on the cloud server is acquired, the corresponding local protocol file address is replaced by the network resource address in the HTML file. For the video, after the network resource address of each video on the cloud server is acquired, the network resource address of each video is placed at a position corresponding to the video in the HTML file.
In addition, in other embodiments of the present invention, in the field of data content sensitivity, considering content security during uploading of rich text content, it is also necessary to perform content security check on text, picture, etc. that are pasted correspondingly while being pasted in combination with cloud storage and cloud content detection services. In an embodiment, a first content detection model for text may be set on the cloud server, before the HTML file is formed and pasted on the rich text editing page, the text content parsed from the pasted content information needs to be called for sensitive information identification by the corresponding first content detection model on the cloud server, and if there is sensitive information, prompt information needs to be returned locally and generation of the HTML file is terminated. The text, image, video and other multimedia files in the rich text content can be respectively subjected to content identification. In an embodiment, a second content detection model for images and videos may be set on the cloud server, and the images and video files parsed from the pasted content information need to call the corresponding second content detection model on the cloud server to identify sensitive information, and if the sensitive information exists, prompt information needs to be returned to the local area and the generation of the HTML file is terminated. When sensitive information exists, the sensitive information in the content can be marked in different forms so as to facilitate the user to locate the sensitive information to be modified. For the sensitive information of the text mode, different color labels can be used for marking, for the sensitive information of the image mode, a corresponding mask color label can be added to the picture, and for the sensitive information of the video mode, sensitive frames in the video can be extracted or marked. Through automatic content detection, the manual auditing cost can be greatly reduced in the batch copying process of rich texts, the content quality is improved, and the platform safety and the user experience are improved.
In order to facilitate understanding of the technical solution provided by the present invention, a preferred embodiment is taken as an example of copying rich text content containing a large number of pictures and videos from a local Word file, so as to describe in detail how to copy Word pictures and texts to corresponding web pages in a local batch without damage for display.
In the preferred embodiment of the present invention, the user first needs to install a client (including but not limited to a local client implemented by java, c++, python, etc.) in the personal computer, the client will monitor a port (e.g. 13332) in the local computer of the user after installation, when the user opens the rich text editor to edit the content, the client establishes a communication relationship with a locally established monitoring service by using WebSocket when the user opens the current editing page, and if the connection is successful, the installed client of the user is prompted to enter a monitoring state, and the monitoring event includes receiving a message, closing a communication channel, and failing to communicate. When the current page is initialized, a monitoring event is registered in the current rich text editing page, when a pasting event occurs on the page, content information of a system pasting board is obtained through a front-end code, text data (text/HTML format) of clipboardData in the pasting event is obtained, and when an obtained data tag is < w: wordDocument >, tag content, operation type (meaning that Word content needs to be pasted) and credential information (appKey, appSecret) needed by a remote cloud storage service are sent to a local client through a websocket. The local client receives the sent message, analyzes and acquires the credential information and the text information and the operation type in the sticky board to be processed, and when the operation type transmitted currently is a word text sticky event, the text information and the non-text multimedia information (picture and video) need to be respectively extracted and processed.
When extracting the picture, the local client can match all picture information in the text file through a regular table format (such as "< img \s [ ] src \s = \s [ '\" ] ([ +\ "]) [' ] ]", and acquire a file protocol file address (such as: file:// C: \Users \addmin\Pictures \640. Png), and then acquire corresponding picture file byte data based on IO capability of the local client.
Similarly, for video information in the rich text content copied from the Word file, ole file information with the type of text/rtf can be obtained from the paste content data of the system paste board, the ole file is decompressed to obtain a [1] ole10native file, the [1] ole10native file contains path information in the file and byte data of the original multimedia file, and therefore the original multimedia file can be obtained through extraction of the [1] ole10native file, and then the original multimedia file is transmitted to a cloud server through a local client to be replaced to obtain a network resource address of a cloud.
In addition, when the pictures and the video files are uploaded to the cloud server, the abstract information of each file can be obtained through an abstract calculation function. The summary information is generated by MD4, MD5, SHA1, SM3, etc. After obtaining all the abstract information of the multimedia files, processing the individual files in a circulating mode, wherein the steps are as follows: and using abstract information of the current file to request a server interface, checking whether the current file is uploaded, if so, using a network resource address returned by the cloud server, if not, judging the size of the current file, if so, slicing the file if the file is greater than a configured slicing uploading threshold value, checking whether byte data after current slicing is uploaded, if not, uploading the slicing, if not, uploading the corresponding slicing serial number and the slicing data to the server, and then using the network resource address returned by the cloud server. The remote file storage service provided by the cloud server may use cloud object storage service (oss) for file storage.
In addition, in the preferred embodiment, content inspection is also performed on text content and uploaded multimedia files.
The content security check for the paste text is as follows: the local client performs label interception processing on the acquired text, for example, the originally acquired text is "< p > < div > and gives dominance to the earnings of the public area owned by the owner according to the management regulations of the community, each person XXX needs to participate in the community management < div > </p >", if the 'XXX' is sensitive information, the acquired text can be processed into the 'according to the management regulations of the community and gives dominance to the earnings of the public area owned by the owner, each person XXX needs to participate in the community pipe', then the text after processing is subjected to sensitive information detection by calling a text content detection model API of the cloud server, different color types are adopted for the keywords in the text according to the returned detection result, for example, the 'XXX' is detected to belong to the sensitive information, and different color labels are used for prompting the 'XXX'. The display of "XXX" as using a red label causes the text to be converted into: < p > < div > according to the management regulations of communities, the income of public areas owned by owners is dominated, and each person < SPAN STYLE = "color: red; text-decoration: line-through" > XXX </span > needs to participate in community management </div > </p >.
In addition, after the picture or video file is obtained, the file can be safely detected through a content detection model API of the picture or video provided by the cloud server, a corresponding mask color label is added to the picture with the sensitive information according to the returned risk detection type, and the sensitive frame extraction and marking are carried out on the video with the sensitive information so as to remind a user whether the multimedia file is illegal or not.
In addition, in the preferred embodiment, in order to visualize the file uploading progress, the client synchronizes the processing progress of the file to the browser end based on websocket every time one file uploading is completed. In particular, when the browser monitors the processing of the message, and when the client sends the message with the progress type, the front end displays the uploading progress through the progress bar. After the current file is uploaded, the network resource address (such as https:// aliyun.files.wpsf042.Tmp. Png) returned by the remote server can be used to replace the original local file protocol address.
When all the files are processed, the client sends the HTML text information with the address replaced and the processed signals to the browser, and when the browser monitors the processed signals, the data transmitted by the client are analyzed, and then the processed HTML is pasted into the rich text editing page of the corresponding text application.
In addition, it should be noted that, the browser-side rich text copying method based on the cloud service in the above embodiment may be essentially executed by a computer program.
