Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the prior art, the web page conversion process transcodes an input file into an available web page file through a corresponding file transcoding web page system. And the user sends the file to be transcoded to the file transcoding webpage system through the client, and then the webpage conversion process is completed through the file transcoding webpage system, so that the webpage file is finally generated. Because of the limited number of types of web page file formats, strict format requirements are placed on the input file prior to transcoding.
In the actual use process, the format of the input file uploaded by the user through the client is complex and various, but the input file format supported by the current file transcoding webpage system is less, so that the transcoding requirements of the input files in various formats are difficult to meet. The problem that the requirement on the format of an input file is high in the existing webpage conversion process is caused, and the success rate of webpage transcoding is further improved.
Based on the above, the embodiment of the invention provides a method, a system and an electronic device for converting a file format, which are used for finally converting the file format into a file format which can be supported by a file transcoding webpage system through preprocessing operation on an input file, so that the format requirement on the original input file in the webpage conversion process is reduced, and the success rate of webpage transcoding is improved.
For the sake of understanding the present embodiment, a method for converting a file format disclosed in the present embodiment will be described in detail.
Referring to a flowchart of a method for converting a file format shown in fig. 1, the method includes the steps of:
step S101, acquiring a resource locator of a file to be transcoded; the resource locator of the file to be transcoded contains file format information of the file to be transcoded.
The resource locator of the file to be transcoded is obtained by the user via the client. Specifically, the files to be transcoded are stored in the corresponding file storage systems in advance, and the resource locators are stored in the corresponding cache databases. And the user sends a request to the cache database through the client, and then the resource locator of the file to be transcoded can be obtained. And for the file to be transcoded locally at the user client, the file to be transcoded can be directly uploaded to the file storage system, and after the uploading is successful, the cache database is updated, and the corresponding resource locator is obtained.
The resource locator of the file to be transcoded contains file format information of the file to be transcoded, for example: the end field of the resource locator contains the format, name information of the file to be transcoded. The file format information is used as key information for determining the file format to be transcoded for use in subsequent steps.
Step S102, downloading the file to be transcoded by using a resource locator of the file to be transcoded, and marking the downloaded file to be transcoded as a first file to be processed; the file format information of the first file to be processed is the same as the file format information of the file to be transcoded.
The step is a file downloading step, the file to be transcoded is downloaded through the resource locator to serve as original processing data, and the original processing data is marked as a first file to be processed, so that the description of the subsequent steps is facilitated. It should be noted that the file format information of the first file to be processed is the same as the file format information of the file to be transcoded, so as to prevent the occurrence of an abnormality in the downloading process.
Step S103, converting the first to-be-processed file into a second to-be-processed file meeting the requirement of the file transcoding webpage according to the file format information of the first to-be-processed file.
The requirements of file transcoding web pages include two categories: format and content. In the implementation process, the format conversion can be firstly carried out on the first file to be processed, and the converted target format is a format supported by a file transcoding webpage system. Because the file has uncertainty in the format conversion process, the content of the converted first to-be-processed file needs to be scanned and judged after the conversion is completed, so that the requirement of the file transcoding webpage on the file format is met.
For example, according to the file format information of the first file to be processed, judging whether the file format meets the requirements of a file transcoding webpage system by judging the file header, the content, the file extension name and the like in the file format information; if format conversion is needed, the first file to be processed is converted into a format supported by the file transcoding webpage system through the corresponding file format conversion service system.
After the format conversion is completed, whether the content of the file to be processed meets the standard of a file transcoding webpage system or not needs to be judged, and if the content does not meet the standard, the file transcoding webpage system is repaired. For example, converting fonts in the file to be processed into fonts supported by a file transcoding webpage system; and formatting the file to be processed in the JSON (JavaScript Object Notation, JS object numbered musical notation) format according to the JSON format.
The first to-be-processed file obtains a second to-be-processed file through format conversion and content restoration, and the second to-be-processed file at the moment meets the requirements of the file transcoding webpage.
Step S104, generating a resource locator of the second to-be-processed file, downloading the second to-be-processed file by using the resource locator of the second to-be-processed file, and using the downloaded second to-be-processed file in a process of file transcoding web pages.
The resource locator of the second file to be processed is obtained through a corresponding cache database in a similar process to the file to be transcoded. After the second to-be-processed file is generated, the second to-be-processed file can be uploaded to the file storage system, and the cache database is updated after the second to-be-processed file is uploaded successfully so as to update the resource locator of the second to-be-processed file.
After the resource locator of the second to-be-processed file is obtained, the file can be used for a file transcoding process, the second to-be-processed file is downloaded, and the downloaded second to-be-processed file is used for a file transcoding webpage process.
According to the method for converting the file format provided by the embodiment, the method is used for finally converting the input file into the file format which can be supported by the file transcoding webpage system through preprocessing operation of the input file, so that the format requirement on the original input file in the webpage conversion process is reduced, and the success rate of webpage transcoding is improved.
In some embodiments, according to the file format information of the first to-be-processed file, the step S103 of converting the first to-be-processed file into the second to-be-processed file meeting the requirement of the file transcoding web page, as shown in fig. 2, includes:
Step S201, obtaining a preset input file support type and an output file support type; the input file support type is the type of the input file supported in the process of transcoding the webpage; the output file support type is the type of the output file supported in the process of transcoding the webpage by the file.
The final result of the file transcoding web page process is the web page type, so that the output file support type can be various files which can be supported by the web page. In a specific embodiment, the output file support types include: presentation output file, form output file, text output file, PDF output file and text output file, and one or more corresponding file formats;
the file format corresponding to the demonstration output file comprises: pptx, ppt;
the file format corresponding to the form output file comprises: xls, xlsx;
the file format corresponding to the text output file comprises: doc, docx;
the file format corresponding to the PDF output file comprises: pdf;
the text format corresponding to the text output file comprises: txt.
The output file is used as a final web page file and can be directly played through a browser, so that the output file is usually a text file, an office file and a related file capable of being edited by text.
Similar to the output file support type, the input file support type is the type of input file supported in the process of transcoding the web page. In a specific embodiment, the input file support types include: a presentation input file, a form input file, a text input file, a PDF input file and a text input file, wherein the file formats correspond to one or more of the above files;
the file format corresponding to the input file is demonstrated, which comprises the following steps: pptx, ppt, pot (PowerPoint template File Format), potx (PowerPoint template File Format), pps (PowerPoint presentation File Format), ppsx (PowerPoint presentation File Format), dps (WPS presentation File Format), dpt (WPS presentation File Format), pptm (PowerPoint File Format), potm (PowerPoint File Format), ppsm (PowerPoint File Format);
the file format corresponding to the form input file comprises: xls (format of Excel 1997-2003), xlt (format of Excel template file), et (format of WPS table file), ett (format of WPS table template file), xlsx (format of Excel 2007 and later), xltx (format of Excel 2007 and later), csv (command-Separated Values, comma Separated Values), xlsb (format of table file with macros), xlsm (format of XML-based and macro-enabled Excel 2007 and later), xltm (format of macro-enabled Excel 2007 and later template file);
The file format corresponding to the text input file comprises: doc (Document format), dot (Word template file), WPS (WPS Document mode), wpt (WPS template file), docx (Word 2007 and later), dotx (template file of Word 2007 and later), docm (macro-enabled Word 2007 and later), dotm (macro-enabled Word 2007 and later);
the file format corresponding to the PDF input file comprises: pdf;
the text format corresponding to the text input file comprises: lrc (lyric lyrics file), C (C language source file), cpp (c++ language source file), h (C language header file), asm (Assembly Language, assembly language file), s (assembly language source program file), java (java source code file), asp (Active Server Page, dynamic server page), bat (batch file), bas (VB module file), prg (Points Ranking Game source program file), cmd (linker configuration file), rtf (Rich Text Format), txt (Text Format file), xml (extensible markup language file), json (JavaScript Object Notation, json object numbered musical notation).
Step S202, format judgment is performed on file format information of a first file to be processed, and whether the first file to be processed meets an input file support type is determined.
After the input file support type and the output file support type are acquired, preliminary judgment is needed to be carried out on the file format of the first file to be processed, and whether the format of the first file to be processed meets the input file support type and the output file support type is determined.
Specifically, in step S202, a header, a content and an extension of a file included in the file format information of the first file to be processed may be obtained first; and then judging whether the first file to be processed meets the input file support type or not by using the file header, the file content and the file extension of the first file to be processed respectively.
If the format of the first file to be processed meets the input file support type and meets the output file support type, the process of transcoding the file into a webpage can be directly carried out without converting the file;
if the format of the first file to be processed does not meet the input file support type, but meets the output file support type, the file conversion is not needed, and the process of transcoding the file into a webpage is directly carried out on the file;
if the format of the first file to be processed meets the input file support type, but does not meet the output file support type; the first file to be processed needs to be converted, step S203 is performed.
In step S203, if the first to-be-processed file satisfies the input file support type and does not satisfy the output file support type, the first to-be-processed file is converted into a second to-be-processed file satisfying the output file support type.
In some embodiments, after the step S103 of converting the first to-be-processed file into the second to-be-processed file meeting the requirement of the file transcoding web page according to the file format information of the first to-be-processed file, it is required to determine whether the converted second to-be-processed file is abnormal. As shown in fig. 3, the method for converting a file format further includes:
step S301, acquiring a preset file format standard; the file format standard is a format standard required by the file in the process of transcoding the webpage.
The format standard refers to the format standard of the file transcoding webpage system for file requirements, and because uncertain abnormal conditions can occur in the file conversion process, the converted second to-be-processed file needs to be subjected to abnormal verification by utilizing the format standard required by the file transcoding webpage system. Standards for file formats may include fonts, content, coding, and the like.
Step S302, judging whether the second file to be processed meets the file format standard.
Step S303, if not, carrying out format conversion on the second file to be processed according to the file format standard.
For example, the file to be processed is a ppt format type file, wherein the font used is A; the file transcoding web page system does not contain the font library of the font A and only supports the font library of the font B. At this time, it is determined by S302 that the second to-be-processed file does not meet the file format standard, and then, according to step S303, the font a in the second to-be-processed file is converted into the font B.
For example, the file to be processed is a json type file, but the content format of the file is not laid out according to the json tag format; at this time, it is determined by step S302 that the second to-be-processed file does not meet the file format standard, and then, according to step S303, the contents of the second to-be-processed file are formatted and typeset again according to the six constructional characters, the character strings, the numbers and the three literal names included in the json tag.
In some embodiments, before the step S102 of downloading the file to be transcoded by using the resource locator of the file to be transcoded and marking the downloaded file to be transcoded as the first file to be processed, it is required to determine whether the resource locator has been processed, so as to determine whether the file to be transcoded has completed format conversion, as shown in fig. 4, and the method for converting the file format further includes:
In step S401, it is determined whether the conversion of the resource locator of the file to be transcoded is completed.
The result of the conversion can be directly set in the resource locator through the mark, and whether the file to be transcoded is converted is judged through judging the mark. If the file to be transcoded has completed conversion, the corresponding tag in the corresponding resource locator also needs to be updated.
Step S402, if yes, the resource locator of the file to be transcoded is used for downloading the file to be transcoded, and the downloaded file to be transcoded is used for the process of transcoding the webpage.
If the file to be transcoded has completed the conversion, it is indicated that the file to be transcoded can meet the requirements of the file transcoding web page system, at this time, the subsequent conversion step can be omitted, the file downloading is directly performed by using the resource locator with the transcoded file, and the file to be transcoded is used for the file transcoding web page process.
The method for converting the file format according to the above embodiment can be known, where the method first obtains a resource locator of a file to be transcoded; the resource locator of the file to be transcoded comprises file format information of the file to be transcoded; then, downloading the file to be transcoded by using the resource locator of the file to be transcoded, and marking the downloaded file to be transcoded as a first file to be processed; the file format information of the first file to be processed is the same as the file format information of the file to be transcoded; according to the file format information of the first file to be processed, converting the first file to be processed into a second file to be processed which meets the requirements of the file transcoding webpage; and then generating a resource locator of the second to-be-processed file, downloading the second to-be-processed file by using the resource locator of the second to-be-processed file, and using the downloaded second to-be-processed file in a process of file transcoding web pages. According to the method, through preprocessing operation on the input file, the input file is finally converted into a file format which can be supported by a file transcoding webpage system, so that the format requirement on the original input file in the webpage conversion process is reduced, and the success rate of webpage transcoding is improved.
Corresponding to the above method embodiment, the embodiment of the present invention further provides a system for converting a file format, where the system is used for a process of transcoding a web page from a file, and a schematic structure of the system is shown in fig. 5, and the system includes:
a file resource locator obtaining module 510, configured to obtain a resource locator of a file to be transcoded; the resource locator of the file to be transcoded comprises file format information of the file to be transcoded;

For a brief description, reference is made to the corresponding content of the preceding method embodiments, where the examples section is not mentioned.
The following describes a file format conversion process in conjunction with a schematic structural diagram of another file format conversion system, as shown in fig. 6.
The client 610 sends the URL of the file to be transcoded to the file transcoding web system 620 for transcoding; the file transcoding web system 620 sends the received URL of the file to be transcoded to the conversion system 630 of the file format for format conversion.
If the URL to be transcoded has been processed, the conversion system 630 in the file format returns the URL of the file directly from the cache database 690 and performs the transcoding process using the file transcoding web system 620.
If the URL to be transcoded is not processed, the conversion system 630 in the file format downloads the file according to the URL to be transcoded, marks the downloaded file to be processed as the first file to be processed, and performs type judgment on the first file to be processed through the file format judgment service system 640. Specifically, the file format determining service system 640 determines whether the file is the input file type supported by the file transcoding web system 620 by reading the file header, the content, and the file extension of the first file to be processed.
If the first to-be-processed file is an input type supported by the file-transcoding web-page system 620, but not an output file type supported by the file-transcoding web-page system 620, the first to-be-processed file is converted into a second to-be-processed file of the file type outputted by the file-transcoding web-page system 620 using the file format conversion service system 650.
The converted second to-be-processed file passes through the file exception checking service system 660 to determine whether the content of the second to-be-processed file meets the file standard of the file transcoding web system 620. And if not, repairing the second to-be-processed file by using the file repairing service module 670. If the second to-be-processed file is a ppt type file and the file font library is not supported by the file transcoding web system 620, converting the fonts in the second to-be-processed file into default fonts supported by the file transcoding web system 620; if the second file to be processed is a json file, but the content format of the file is not laid out according to the json tag format, the content of the second file to be processed is formatted and typeset again according to six construction characters, character strings, numbers and three literal names contained in the json tag.
The second pending file is uploaded to the distributed file storage system 680 and the URL of the second pending file is obtained, where the second pending file meets the output file type of the file transcoding web system 620. While saving the URL to the cache database 690 and returning the URL to the file transcoded web system 620.
The file-transcoding web-page system 620 downloads the file from the distributed file-storage system 680 according to the URL of the second pending file and uses the file for subsequent processes of the file-transcoding web-page.
According to the conversion system of the file format, which is mentioned in the embodiment, the system can finally convert the file format into the file format which can be supported by the file transcoding webpage system through preprocessing operation on the input file, so that the format requirement on the original input file in the webpage conversion process is reduced, and the success rate of webpage transcoding is improved.
