[0085] The following description of exemplary embodiments of the present invention is made in conjunction with the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0086] The acquisition, storage, use, and processing of data in this application's technical solution comply with relevant national laws and regulations.

[0087] Figure 1 FIG. 1 is a schematic diagram of the main process of the method for printing a file according to the first embodiment of the present invention. As an embodiment of the present invention, Figure 1 As shown, the method for printing a file may include:

[0088] Step 101: Receive a print request, where the input parameters of the print request include a service serial number and an installation mode.

[0089] First, a print request from the front end is received, wherein the input parameters of the print request include at least a business serial number and an installation mode, so that file printing can be realized through the business serial number and the installation mode in subsequent steps.

[0090] Step 102 , querying the print file record table according to the business serial number to determine whether the business serial number exists in the print file record table; if so, executing step 103 ; if not, executing step 104 .

[0091] In this step, the print file record table is queried according to the service serial number to determine whether the service serial number exists in the print file record table; wherein the print file record table stores each service serial number and its corresponding session identifier and storage timestamp.

[0092] Step 103: Obtain the session identifier corresponding to the service serial number from the print file record table.

[0093] If the business serial number in the print request input parameter exists in the print file record table, the session ID corresponding to the business serial number is directly obtained from the print file record table. Optionally, if there are multiple session IDs corresponding to the business serial number in the print file record table, the session ID with the most recent timestamp is obtained so that the front-end displays the most recent file.

[0094] It should be pointed out that if the business serial number in the print request input parameter exists in the print file record table, it means that the file has been printed. In order to avoid duplicate printing, the front end can directly obtain the printed file for display.

[0095] Step 104 : acquiring data to be printed, generating a file according to the installation mode and the preset printing mode, and thereby generating a session identifier or uniform resource locator corresponding to the file.

[0096] If the business serial number in the print request input parameter does not exist in the print file record table, it means that the file has not been printed yet. Therefore, it is necessary to obtain the data to be printed based on the business serial number, and then generate a file based on the installation mode in the print request input parameter and the pre-configured print mode. Then, a session identifier or uniform resource locator (URL) corresponding to the file is generated. Optionally, the pre-configured print mode is Flash mode or PDF mode, and the business personnel can configure the print mode as needed.

[0097] In the embodiment of the present invention, different processing methods are used for different installation modes. The installation mode can be configured when initiating a print request or when developing a business, and the embodiment of the present invention does not limit this.

[0098] If the installation mode is selected from one of the following: watermark mode, seal mode, watermark and seal mode; then step 104 may include: obtaining the data to be printed according to the business serial number, thereby generating a file according to the installation mode and the preset printing mode; storing the file locally, writing the storage address of the file into the session, thereby generating a session identifier corresponding to the storage address of the file. If the installation mode in the print request input parameter is one of the watermark mode, seal mode, watermark and seal mode, then obtaining the data to be printed according to the business serial number in the print request input parameter, then generating a file according to the loading mode and the preset printing mode (such as flash mode or PDF mode), then storing the generated file locally on the server, and finally writing the storage address of the file into the session, thereby generating a session identifier (session ID) corresponding to the file.

[0099] Optionally, after writing the storage address of the file into the session to generate a session identifier, the method further includes writing the service serial number, the session identifier, and the current timestamp into a print file record table. To avoid duplicate printing of files, the service serial number, the session identifier, and the current timestamp (i.e., the timestamp at which the service serial number and session identifier are written into the print file record table) may be written into the print file record table to facilitate querying whether the file has been printed.

[0100] Optionally, obtaining the data to be printed based on the service serial number, thereby generating a file based on the installation mode and a preset printing mode, includes: obtaining the storage address of the data to be printed based on the service serial number, thereby obtaining the data to be printed; generating a file based on the preset printing mode and the data to be printed; and performing installation processing on the file based on the installation mode; wherein the installation processing includes one of the following: adding a watermark, stamping, or adding a watermark and stamping. Generally speaking, the backend stores the data to be printed locally on the server and stores the storage address of the data to be printed in the session. Therefore, the storage address of the data to be printed can be obtained from the session based on the service serial number, thereby obtaining the data to be printed based on the storage address. A PDF file is then generated based on a preset printing mode (e.g., PDF mode), and finally, the PDF file is subjected to installation processing based on the installation mode. For example, if the installation mode is to add a watermark, a watermark is added to the PDF file; if the installation mode is to stamp, a stamp is stamped on the PDF file; and if the installation mode is to both watermark and stamp, a watermark and a stamp are added to the PDF file.

[0101] If the installation mode is the signature mode; then step 104 may include: obtaining the data to be printed according to the business serial number, thereby generating a file according to the preset printing mode; calling the signature interface, the input parameter of the signature interface is the file; receiving the uniform resource locator returned by the signature interface. In an embodiment of the present invention, if the installation mode is the signature mode, it is implemented by calling a third-party interface. Specifically, the storage address of the data to be printed is obtained from the session according to the business serial number, thereby obtaining the data to be printed according to the storage address, and then generating a PDF file according to the preset printing mode (such as PDF mode), and then calling the signature interface provided by the third party, calling the interface with the input parameter of the PDF file, and finally receiving the URL returned by the signature interface. It should be pointed out that after the third party receives the signature request through the signature interface, it will sign the file and store the processed file in the URL for front-end loading.

[0102] If the loading mode is empty, step 104 may include: obtaining the data to be printed based on the service sequence number, thereby generating a file according to a preset printing mode; storing the file locally; and writing the storage address of the file into the session, thereby generating a session identifier corresponding to the storage address of the file. In an embodiment of the present invention, if the loading mode is empty, the storage address of the data to be printed is obtained from the session based on the service sequence number, thereby obtaining the data to be printed based on the storage address, then generating a PDF file according to a preset printing mode (such as PDF mode), then storing the generated PDF file locally on the server, and finally writing the storage address of the file into the session, thereby generating a session identifier corresponding to the PDF file. Optionally, after writing the storage address of the file into the session, thereby generating a session identifier, the process further includes: writing the service sequence number, the session identifier, and the current timestamp into a print file record table. To avoid duplicate printing of files, the service sequence number, session identifier, and current timestamp (i.e., the timestamp when the service sequence number and session identifier are written into the print file record table) may be written into the print file record table, thereby facilitating querying whether the file has been printed.

[0103] Step 105: Return the session identifier or the uniform resource locator.

[0104] After the session identifier or uniform resource locator is generated, the session identifier or uniform resource locator is returned to the front end, and the front end obtains the corresponding file according to the session identifier or uniform resource locator for display.

[0105] The method provided by the embodiment of the present invention can be encapsulated as an openWin method, and the front end calls the openWin method to implement the technical solution of the present application. The embodiment of the present invention can integrate multiple printing modes and installation modes. After development is completed, each business module only needs to configure parameters to meet the corresponding requirements without affecting the original business module code.

[0106] Based on the various embodiments described above, it can be seen that the embodiments of the present invention query the print file record table based on the business sequence number to determine whether the print file record table contains the business sequence number; if so, obtain the session identifier from the print file record table; if not, obtain the data to be printed, generate the file according to the installation mode and the preset printing mode, and thus generate the session identifier or uniform resource locator. This technical means solves the technical problem of high development costs in the prior art. The embodiments of the present invention implement file printing and secondary installation by dynamically configuring the installation mode and the printing mode. Each business module only needs to call a unified printing method and configure the corresponding parameters to achieve the corresponding requirements and meet the personalized needs of users. This not only reduces development costs but also decouples file printing from business functions.

[0107] Figure 2 Schematic diagram of the main process of the method for printing a file according to the second embodiment of the present invention. As another embodiment of the present invention, Figure 2 As shown, the method for printing a file may include:

[0108] Step 201: Receive a print request, where the input parameters of the print request include a service serial number and an installation mode.

[0109] Step 202, query the print file record table according to the business serial number to determine whether the print file record table contains the business serial number; if so, execute step 203; if not, execute step 204, step 207 or step 210.

[0110] The print file record table stores each service serial number and its corresponding session identifier and storage timestamp. The print file record table is queried to determine whether the service serial number and its corresponding session identifier and storage timestamp in the print request input parameter already exist.

[0111] Step 203: Obtain the session identifier corresponding to the service serial number from the print file record table.

[0112] If the print request input parameter contains the business serial number in the print file record table, it means that the file has already been printed. To avoid duplicate printing, you can directly obtain the session ID corresponding to the business serial number from the print file record table. It should be noted that if the print file record table contains multiple session IDs corresponding to the business serial number, the session ID with the most recent timestamp is obtained so that the front-end displays the most recent file.

[0113] If the installation mode is selected from the following: watermark mode, seal mode, watermark and seal mode, then execute steps 204-206. If the installation mode is signature mode, then execute steps 207-209. If the installation mode is empty, then execute step 210.

[0114] Step 204: Acquire the data to be printed according to the business serial number, thereby generating a file according to the installation mode and the preset printing mode.

[0115] Optionally, step 204 may include: obtaining the storage address of the data to be printed based on the service serial number, thereby obtaining the data to be printed; generating a file based on a preset printing mode and the data to be printed; and performing installation processing on the file based on the installation mode; wherein the installation processing includes one of the following: adding a watermark, stamping, or adding a watermark and stamping. The backend stores the data to be printed locally on the server and stores the storage address of the data to be printed in the session. Therefore, the storage address of the data to be printed can be obtained from the session based on the service serial number, thereby obtaining the data to be printed based on the storage address. The file is then generated based on the preset printing mode, and finally, the file is installed based on the installation mode. For example, if the installation mode is adding a watermark, the file is watermarked; if the installation mode is stamping, the file is stamped; if the installation mode is watermark and stamping, the file is watermarked and stamped.

[0116] Optionally, the file is subjected to installation processing according to the installation mode, including: querying the print file record table according to the business serial number to determine whether the business serial number exists in the print file record table; if so, obtaining the session identifier corresponding to the business serial number from the print file record table; if not, performing installation processing on the file according to the installation mode. In an embodiment of the present invention, files can be subjected to installation processing in a synchronous or asynchronous manner. If the file is subjected to installation processing in an asynchronous manner, it is necessary to determine whether the file has been printed by querying the print file record table to prevent duplicate printing. Therefore, before performing installation processing on the file, first query the print file record table to determine whether the business serial number in the print request input parameter exists. If so, it means that the file has been printed. Then, the session identifier corresponding to the business serial number is directly obtained from the print file record table. If not, the file is subjected to installation processing according to the installation mode in the print request input parameter.

[0117] Step 205: Store the file locally and write the storage address of the file into the session, thereby generating a session identifier corresponding to the storage address of the file.

[0118] Step 206: Write the service serial number, the session identifier, and the current timestamp into the print file record table.

[0119] Step 207: Acquire the data to be printed according to the business serial number, thereby generating a file according to a preset printing mode.

[0120] If the installation mode is the signature mode, it is implemented by calling a third-party interface. Specifically, the signature interface provided by the third party is called to receive the URL returned by the signature interface.

[0121] Step 208: calling a signature interface, wherein the input parameter of the signature interface is the file.

[0122] Step 209: Receive the uniform resource locator returned by the signature interface.

[0123] Step 210, obtaining the data to be printed according to the business serial number, thereby generating a file according to a preset printing mode, storing the file locally, and writing the storage address of the file into the session, thereby generating a session identifier corresponding to the storage address of the file.

[0124] If the loading mode is empty, the storage address of the data to be printed is obtained from the session according to the business serial number, and the data to be printed is obtained according to the storage address. Then, the file is generated according to the preset printing mode, and the generated file is stored locally on the server. Finally, the storage address of the file is written to the session, thereby generating a session identifier corresponding to the PDF file.

[0125] Step 211: Return the session identifier or the uniform resource locator.

[0126] The embodiments of the present invention have the following beneficial effects: when the front-end page display results are modified according to user needs, system changes are reduced, which facilitates system maintenance; and the system is more flexible, and the front-end page can be quickly adjusted to improve system functions; development costs are saved and the response speed to user needs is improved.

[0128] Step 301: Receive a print request, where the input parameters of the print request include a service serial number and an installation mode.

[0129] Step 302 , query the print file record table according to the business serial number to determine whether the business serial number exists in the print file record table; if so, execute step 303 ; if not, execute step 304 .

[0130] Step 303: Obtain the session identifier corresponding to the service serial number from the print file record table.

[0131] Step 304: Acquire the data to be printed according to the business serial number, thereby generating a file according to a preset printing mode.

[0132] Step 305: Obtain the installation mode in the print request input parameter, where the installation mode is selected from one of the following: watermark mode, seal mode, or watermark and seal mode; then proceed to step 306. If the installation mode is signature mode, proceed to step 309. If the installation mode is null, proceed to step 307.

[0133] Step 306: perform installation processing on the file according to the installation mode, such as adding a watermark, stamping, or adding a watermark and stamping.

[0134] Step 307: Store the file locally and write the storage address of the file into the session, thereby generating a session identifier corresponding to the storage address of the file.

[0135] Step 308: Write the service serial number, the session identifier, and the current timestamp into the print file record table.

[0136] Step 309: calling the signature interface, where the input parameter of the signature interface is the file.

[0137] Step 310: Receive the uniform resource locator returned by the signature interface.

[0138] Step 311: Return the session identifier or the uniform resource locator.
