Description

Technical Field

[0001] The present application relates to the field of document conversion, and in particular to a file conversion management method, device, equipment and medium for online preview. Background Art

[0002] With the popularity of mobile terminals, the display of various documents on mobile terminals has become a common phenomenon. There are currently three display methods: the first is to download the document to the mobile terminal first, and then read the document through the reading software on the mobile terminal, but this method not only requires the download of the document, but also requires the mobile terminal to be equipped with various reading software. The second is to convert the document into a picture format and read it through the mobile terminal's built-in picture reading function, but this method is not convenient for readers to edit the document. The last one is to convert the document into HTML format online to achieve a pure web page effect. Converting Word documents to pure web pages in real time, the generated page is concise, especially with good adaptation effects on mobile terminals, and considering the reading experience of mobile terminals more while trying to restore the document content. The pictures and tables in Word documents can be handled well, and the content of the document can be perfectly restored. However, in daily life, it is often encountered that a large number of users read the same document in a short period of time. If the document is converted every time, a lot of server resources will be wasted.

[0003] Therefore, there is an urgent need for a document conversion management method for online preview. Summary of the invention

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0021] The technical solutions provided by the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The implementation of the analysis method involved in the embodiments of the present application can be a terminal device or a server, and the present application does not impose any special restrictions on this. For the convenience of understanding and description, the following embodiments are described in detail using the server as an example.

[0022] It should be noted that the server may be a single device or a system consisting of multiple devices, that is, a distributed server, and this application does not make any specific limitation on this.

[0023] like Figure 1 As shown, the embodiment of the present application provides a file conversion management method for online preview, including:

[0024] S101: receiving preview request information of a target document, and establishing a document conversion thread according to the preview request information, wherein the preview request information at least includes a download path, a document name, and a document unique identifier of the target document.

[0025] When a user receives a document, he can choose to download it and then select a mobile application to preview it, but this method is time-consuming and labor-intensive, and cannot guarantee the security of the document. At this time, you can choose to long-press the document to select online preview. The document conversion server will obtain the file content according to the download link, and convert it into a preview file that can be directly opened and return it to the mobile phone. Therefore, the document conversion server first needs to receive the preview request information for the target file sent by the user. In order to facilitate the acquisition of the content of the target document, the preview request information should at least include the download path, document name and document unique identifier of the target document. Among them, the document unique identifier is an identifier generated by the mobile terminal based on the document name and download path of the target document, and is unique. For ease of understanding, it can be understood as the hash value of the target document.

[0026] S102: Determine a preset document identification set, in which the document unique identification corresponding to the document being converted is stored.

[0027] After obtaining the document unique identifier of the target document, various information about the target document in the server can be determined through the document unique identifier, such as whether the target document has been converted in the server or is being converted.

[0028] Before determining various types of information of the target document in the server through the document unique identifier, it is first necessary to determine a preset document identifier set. Since the solution provided by this application is to solve the situation where a large number of users simultaneously send preview requests for the same document in a short period of time, the document identifier set stores the document unique identifiers corresponding to the documents that are in the process of conversion. In other words, the document identifier set only stores multiple document unique identifiers, and the documents corresponding to these document unique identifiers are in the process of conversion. Of course, the document identifier set can also store document unique identifiers corresponding to documents that have been converted.

[0029] S103: traversing the document identification set, querying whether the document unique identification corresponding to the target document is stored in the document identification set.

[0030] After determining the preset document identification set, in order to check whether the target document is in the process of being converted in the server, it is necessary to traverse the document identification set to query whether the document identification set stores the document unique identification corresponding to the target document. If it exists, it means that the user has submitted a preview request for the target document in advance, and the target document is in the process of being converted.

[0031] S104: If the document unique identifier does not exist in the document identifier set, the document unique identifier is stored in the document identifier set, and the format of the target document is converted.

[0032] If the document unique identifier does not exist in the document identifier set, it means that no user has submitted a preview request for the target document in a short period of time, that is, the target document is not included in the documents that are being converted in format on the server. Therefore, the target document needs to be converted into a document format that can be directly browsed by the mobile terminal. At the same time, in order to avoid other users uploading preview requests for the target document later, causing the server to perform repeated conversion, the document unique identifier of the target document needs to be uploaded to the document identifier set, so that after subsequent users upload preview requests for the target document, the document conversion thread will query the document unique identifier of the target document in the document identifier set, thereby giving up the simultaneous conversion of the target document.

[0033] S105: If the target document is successfully converted into a preview document, the preview document and the document unique identifier are stored in a database.

[0034] If the target document is successfully converted into a preview document that can be directly browsed online on the mobile terminal, the preview document and the document unique identifier of the preview document, ie, the target document, are stored in the database of the server.

[0035] S106: Send the preview document to the client and release the document conversion thread.

[0036] After the preview document is stored, it is also necessary to send the preview document to the mobile terminal so that the user can browse the content of the target file online through the mobile terminal in time. At the same time, it is also necessary to release the document conversion thread so that other tasks can mobilize the thread.

[0037] In one embodiment, since in the technical solution provided by the present application, the document identification collection only stores the document unique identification corresponding to the document being converted, when the conversion of the target document is completed, the document unique identification corresponding to the target document in the document identification collection should be deleted, so as to prevent the document conversion process from being delayed after subsequent users upload preview requests.

[0038] In one embodiment, since multiple document conversions for the same target document in a short period of time will cause a large amount of server resource waste, after querying whether there is a document unique identifier corresponding to the target document in the document identifier set, if there is, it means that a user has previously issued a document conversion request for the target document, and the conversion operation is currently being performed, so the document conversion thread suspends the conversion request for the target document. And after the conversion is completed, the preview document obtained by conversion can be automatically sent to the suspended document conversion thread to prevent the user from performing further operations. At the same time, a preset first time interval can also be determined, and after the first time interval, the document unique identifier corresponding to the target document is queried again. Because when the target document conversion succeeds or fails, the document unique identifier will be deleted from the document identifier set, so it is necessary to query again after a period of time.

[0039] In one embodiment, if the target document has been converted in the server and a user makes a preview request for the same target document, if the target document is converted again at this time, a large amount of server resources will be wasted. Therefore, since the converted preview document and the corresponding document unique identifier have been stored in the database, before querying the document unique identifier in the document identifier set, it is possible to query in the database whether the document unique identifier exists. If so, it means that the document has been converted, that is, the preview document corresponding to the target document exists in the database. At this time, the preview document corresponding to the target document can be directly retrieved from the database, thereby omitting the document conversion process and improving the efficiency of file preview.

[0040] Furthermore, when the server has been in operation for a long time, a large number of preview documents and a large number of document unique identifiers will be stored in the database. At this time, it will take a lot of time to match the document unique identifier of the target document from the database. Therefore, you can first match from the cache of the server within a preset historical time length. For example, query from the cache of the server within one day whether the target document has been converted. If the document unique identifier of the target document exists in the cache, then take out the preview document from the cache; if not, then match from the database to reduce time consumption.

[0041] In one embodiment, since there are many preview files stored in the database, it will take a long time to query the database for the corresponding preview document or document unique identifier. Therefore, the preview times of each document in the database within a preset time range can be counted, and the document unique identifiers in the database can be sorted according to the preview times, so that in the process of traversing the database, each file can be identified in the order of the preview times, thereby reducing the traversal time and improving the preview efficiency of the document.

[0042] In one embodiment, the preview document is a document in HTML format, that is, the target document is converted into a pure web page format to facilitate browsing of the document by mobile terminals. The page generated by the document in HTML format is concise, especially well adapted to mobile terminals, and can also well ensure the security of the document, improve readability, and improve work efficiency.
