It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
FIG. 1 illustrates an exemplary architecture 100 to which embodiments of the methods of the present disclosure for generating a file or apparatus for generating a file may be applied.
As shown in fig. 1, a system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 is used as a medium to provide communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.
The terminal devices 101, 102, 103 interact with the server 105 via the network 104 to receive or send messages or the like. Various client applications can be installed on the terminal devices 101, 102, 103. For example, search class applications, instant messaging class applications, browser class applications, shopping class applications, social platform software, and the like.
The terminal devices 101, 102, 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices including, but not limited to, smartphones, tablet computers, electronic book readers, laptop and desktop computers, and the like. When the terminal devices 101, 102, 103 are software, they can be installed in the above-listed electronic devices. Which may be implemented as multiple software or software modules (e.g., multiple software or software modules for providing distributed services) or as a single software or software module. The present invention is not particularly limited herein.
The server 105 may be a server providing various services, such as a back-end server responding to file generation requests sent by the terminal devices 101, 102, 103. The server 105 may receive and process a file generation request sent by the client for requesting generation of a PDF file containing the target content, and generate a PDF file required by the client. Further, the server 1005 may return the generated storage address of the PDF file required by the client to the terminal device so that the terminal device may acquire the requested PDF file.
Various applications may also be installed on the server 105. Such as a search class application, an instant messaging class application, a browser class application, etc. The server 105 may complete rendering of the tab page according to the target content indicated by the file generation request sent by the client by using the browser installed therein, to obtain the tab page containing the target content.
It should be noted that, the method for generating a file provided by the embodiment of the present disclosure is generally performed by the server 105, and accordingly, the apparatus for generating a file is generally disposed in the server 105.
The server 105 may be hardware or software. When the server 105 is hardware, it may be implemented as a distributed server cluster formed by a plurality of servers, or as a single server. When server 105 is software, it may be implemented as multiple software or software modules (e.g., multiple software or software modules for providing distributed services), or as a single software or software module. The present invention is not particularly limited herein.
It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for generating a file according to the present disclosure is shown. The method for generating a file comprises the steps of:
in step 201, in response to receiving a file generation request sent by a client, a tag page corresponding to the file generation request is determined.
In this embodiment, the execution subject (e.g., the server 105 shown in fig. 1) of the method for generating a file may receive a file generation request sent by a client (e.g., the terminal devices 101, 102, 103 shown in fig. 1), and determine a tab page corresponding to the question generation request according to the file generation request. The tab page may be a tab page of a browser installed on the execution body.
The file generation request may be used to request generation of a PDF (Portable Document Format ) file containing the target content. The target content can be set by a user of the client according to actual application requirements. For example, the target content may be a piece of text specified by the client, a web page, and so on.
According to different application scenes or actual application requirements, various modes can be flexibly adopted to determine the tag page corresponding to the file generation request.
For example, after receiving the file generation request, a tab page may be created using the browser as the tab page corresponding to the file generation request. For another example, after receiving the file generation request, it may be first determined whether the browser currently has a tab page created that is in an idle state. If so, the currently created tab page in the idle state can be used as the tab page corresponding to the file generation request. If not, a tab page can be created by using the browser as the tab page corresponding to the file generation request.
Step 202, rendering the tab page according to the target content to generate the tab page containing the target content as a target tab page.
In this embodiment, the execution body may render the tab page based on the target content to obtain the tab page for presenting the target content. According to different practical application requirements, different methods can be adopted to complete the rendering process of the label page.
For example, the execution body may complete the rendering of the tab page using the functions provided by the browser installed therein. For another example, the execution body may call a rendering interface corresponding to a preset tab page to complete rendering of the tab page. The rendering interface corresponding to the tab page may be developed and set in advance by a technician.
Step 203, a PDF file corresponding to the target tab page is generated.
In this embodiment, the execution body may generate the corresponding PDF file according to the generated tab page including the target content. According to different practical application requirements, PDF files corresponding to the target tag pages can be generated by different methods.
For example, the execution subject may generate a PDF file corresponding to the target tab page using a function provided by a browser installed therein. For another example, the executing body may generate a PDF file corresponding to the target tab page by using a conversion interface corresponding to the preset tab page. The conversion interface can be developed and set in advance by a technician.
In some optional implementations of the present embodiment, after generating the PDF file corresponding to the target tab page, the generated PDF file may be further stored and a storage address of the PDF file may be acquired. Then, the storage address of the PDF file may be returned to the client so that the client may acquire the generated PDF file according to the storage address.
Alternatively, the generated PDF file may be stored in a file memory.
In some optional implementations of this embodiment, the browser corresponding to the tab page corresponding to the file generation request may be a headless browser.
Since the headless browser does not launch the graphical user interface of the browser, all time to load page styles, render pages, etc. to render pages is saved. Therefore, compared with the tag page of the common browser, the tag page of the headless browser can save all time for presenting the tag page, so that the service efficiency of the tag page is improved, and the efficiency of generating PDF files is further improved.
In some optional implementations of the present embodiment, a preset tab page corresponding to the target content may be determined as a tab page corresponding to the file generation request according to the target content.
At this time, tag pages corresponding to different target contents, respectively, may be preset by a technician. The corresponding relation between the target content and the tab page can be flexibly set according to actual application requirements or different application scenes.
For example, the correspondence relationship between the attribute information of the target content and the tab page may be set in advance. As an example, the attribute information may include information indicating whether the target content includes an image. If the attribute information indicates that the target content includes an image, one tab page may be randomly selected from the tab pages that have been created at present as a tab page corresponding to the target content. If the attribute information indicates that the target content does not include an image, a new tab page can be created by using the browser as a tab page corresponding to the target content.
Alternatively, the page style corresponding to the target content may be determined first, and then a tab page having the page style corresponding to the target content may be determined as the tab page corresponding to the target content.
The page style may be used to indicate front-end design information such as style and layout of the tab page. At this time, the technician may design different page styles for the tab page in advance according to an actual application scenario or an actual application requirement.
The corresponding relation between the target content and the page style can be flexibly set. For example, a page style corresponding to the target content may be determined according to the type of the target content. It should be appreciated that different types of partitioning may be performed for the target content, depending on the application scenario. As an example, the type classification may be performed for the target content according to the domain to which the target content belongs.
At this time, the type of the target content may be determined first, and then the page style of the tab page corresponding to the type of the target content may be determined. A tab page having the determined page style may then be determined as a tab page corresponding to the target content.
With continued reference to fig. 3, fig. 3 is a schematic diagram 300 of an application scenario of the method for generating a file according to the present embodiment. In the application scenario of fig. 3, the user may send a PDF generation request to the server 302 by using the mobile phone 301 used by the user to request to generate a PDF file corresponding to the document. Meanwhile, the user can send the document required to generate the corresponding PDF file to the server 302 using the mobile phone 301 used by the user.
The server 302 may render the tab page in an idle state created in advance by the headless browser 3021 installed thereon to generate a tab page in which the document content is presented. Then, the server 302 may call the PDF conversion function of the headless browser 3021 to convert the generated tab page presenting the document content into a corresponding PDF file.
After that, the server 302 may store the generated PDF file and acquire the storage address 303. The server 302 may then return the storage address 303 to the handset 301 used by the user. Further, the user can acquire a PDF file corresponding to the document according to the storage address 303.
In the prior art, the generation of the PDF file is generally realized by a client. Therefore, functional development for generating PDF files needs to be performed separately for different clients (e.g., clients of different operating systems, etc.). Meanwhile, there may be some differences (e.g., differences in page styles, etc.) between PDF files generated by different clients for the same content. In addition, when updating the function of generating the PDF file provided by the client, a new client needs to be released so that the updated function can be used only by the user downloading and installing the new client.
The method for generating the file provided by the disclosure realizes the generation of the PDF file by using the server. Therefore, the workload of developing each client is eliminated, and the generated PDF files do not have differences for the same content. Meanwhile, the relevant updating of the function for generating the PDF file is also performed at the server side, so that the time for a user to wait for updating the client side can be saved. Thus, stability and efficiency of the entire process of generating the PDF file can be ensured.
With further reference to FIG. 4, a flow 400 of yet another embodiment of a method for generating a file is shown. The process 400 of the method for generating a file comprises the steps of:
in step 401, in response to receiving the file generation request sent by the client, it is determined whether the resource pool includes a tab page corresponding to the file generation request.
In this embodiment, the resource pool may include several tab pages created in advance.
The specific execution process of the tag page corresponding to the file generation request in this step may refer to the related description in the corresponding embodiment of fig. 2, and will not be described herein.
In step 402, in response to determining that the resource pool includes a tab page corresponding to the file generation request, the tab page corresponding to the file generation request is obtained from the resource pool.
In this embodiment, if the resource pool includes the tag page corresponding to the file generation request, the tag page corresponding to the file generation request may be directly obtained from the resource pool, so that the process of creating and loading the tag page may be omitted.
In step 403, in response to determining that the tag page corresponding to the file generation request is not included in the resource pool, the tag page corresponding to the file generation request is created.
Step 404, rendering the tab page according to the target content to generate the tab page containing the target content as the target tab page.
Step 405, a PDF file corresponding to the target tab page is generated.
The specific implementation of steps 404 and 405 described above may refer to the relevant descriptions of steps 202 and 203 in the corresponding embodiment of fig. 2, and will not be repeated here.
In some alternative implementations of the present embodiment, the resource pool may be constructed by:
step one, resource configuration information of each page style in at least one preset page style is respectively obtained.
In this step, at least one page style may be designed and developed by a technician according to an actual application requirement or a specific application scenario. The resource configuration information of the page style may be used to indicate the number of tab pages in the resource pool having a corresponding page style.
And step two, for the page style in at least one page style, creating a corresponding number of tab pages with the page style according to the resource configuration information of the page style.
For example, the resource configuration information of the page pattern "a" indicates that the number of tab pages having the page pattern "a" in the resource pool is "N". At this time, the "N" tab pages may be created in advance, and each of the "N" tab pages is loaded with the page style "a".
Alternatively, the resource configuration information of each page style in the at least one page style may be stored in a dynamic configuration file.
Alternatively, the resource allocation values of the page styles may be used to indicate the minimum and maximum numbers of tab pages in the resource pool that have corresponding page styles. Wherein the minimum number may refer to the number of tab pages that the page style requires least occupancy at idle time. The maximum number may refer to the number of tab pages that the page style occupies most when the service is busy.
By setting the minimum number of tab pages corresponding to the page patterns, the instant response of the request of the client at the idle time can be ensured without waiting for the time of creating the tab pages and loading the page patterns by the tab pages. By setting the maximum number of tag pages corresponding to the page style, the file generation request for the same page style can be controlled not to occupy excessive computer resources (such as CPU resources of a central processing unit) of the whole server, so that response processing of file generation requests for other page styles is reserved.
Alternatively, overall total resource configuration information for the entirety of at least one page style may also be obtained. At this time, the total resource configuration information may be used to indicate a maximum total number of tab pages in the resource pool. Therefore, the upper limit of the number of the tag pages in the resource pool is controlled, the utilization rate of the PDF generation function to the computer resources of the server side can be effectively controlled, and the overall performance and service stability of the server side are ensured.
At this time, after the total number of the tag pages in the resource pool reaches the maximum total number, a prompt message may be returned to the client for the file generation request received again, so as to prompt that the current service is busy and the processing cannot be performed.
Optionally, after the total number of the tag pages in the resource pool reaches the maximum total number, the processing capability of the server can be further improved by expanding the computer resources of the server. For example, the number of processing terminals at the server side is increased, etc. At this time, the maximum total number corresponding to the resource pool can be raised.
Alternatively, the at least one page style developed in advance may be stored in the file memory. At this time, when the service of the server is started, the content of the configuration file storing the resource configuration information and the total resource configuration information corresponding to at least one page style may be read, and the configuration of the tag page may be completed according to the read content.
Optionally, the above configuration file may further store a file storage address of at least one page style, so as to facilitate processing of each page style.
As an example, at service start-up of the server, the server may read the content in the configuration file and then download each page style to the local. And then generating a corresponding number of tab pages according to the resource configuration information corresponding to each page style.
Optionally, when the service of the server is started, the server reads the content in the configuration file, downloads each page style to the local, and then can create the local page style file as the symbol link of the page style file in the corresponding file memory, so as to ensure the stability of the process of recording the page style.
Optionally, when the configuration file of the resource pool has an update, or when the page style has an update, each updated page style file may be downloaded again to the local, and then a corresponding number of tab pages are generated or the existing corresponding tab pages are refreshed according to the corresponding resource configuration information. At the same time, the corresponding symbol connection may be updated.
Thus, the real-time updating of various page styles can be realized without the need of upgrading the client. Therefore, the time that the user waits for the client to upgrade and then installs the new version of the client to use the updated page style is saved.
Optionally, after determining the tab page corresponding to the file generation request, the executing body may start a timer to control the total time of the process of rendering the tab page corresponding to the file generation request and generating the corresponding PDF file, so as to avoid congestion situations such as excessively long response time for the file generation request.
Alternatively, after the PDF file is generated, the tag page corresponding to the file generation request may be emptied through an operation such as refreshing the page, that is, the target content in the tag page may be emptied. The tag page after the flush process may then be returned to the resource pool.
Optionally, when the resource pool is utilized to perform management control on the tab pages, after receiving the file generation request, the page style of the corresponding tab page may be determined according to the target content, and then whether the tab page with the page style in an idle state exists is searched in the resource pool. If so, a tab page in an idle state with the page style may be used. If not, it may be determined whether the total number of tab pages in the current resource pool reaches a corresponding upper limit, and whether the number of tab pages having the page style reaches the upper limit. If the upper limit is reached, prompt information for prompting that the current service resources are insufficient and the like can be returned to the client. Otherwise a new tab page with the page style may be created in response to the file generation request.
Optionally, for each page style in the at least one page style, the number of tabbed pages having the page style in the resource pool may be monitored, and in response to determining that the idle time of the tabbed pages having the page style in the resource pool is greater than a preset idle threshold, the tabbed pages may be reclaimed. In response to determining that the total number of tab pages having the page style in the resource pool exceeds the minimum number of tab pages corresponding to the page style, recycling a portion of the tab pages to ensure that the number of tab pages having the page style in the resource pool is the corresponding minimum number.
