Detailed Description
In order to make the technical scheme, the technical problems to be solved and the technical effects of the present invention more clearly apparent, the following technical scheme of the present invention is clearly and completely described with reference to the specific embodiments.
The first embodiment is as follows:
with reference to fig. 1, this embodiment provides a method for printing an OFFICE template of a unified government affairs service, which includes the following steps:
and S1, forming a plurality of printing templates by a client of the business application system through local OFFICE software, and storing the printing templates in a server of the business application system.
And S2, carrying out API packaging operation by the service application system to form a local HTTP service, and further forming instruction data to be transmitted to the server.
The API wrapping operation specifically includes a bookmark operation and a table operation. And bookmark updating operation or table updating operation carried out by the service system respectively forms instruction data, and the instruction data are transmitted to the server side for storage.
And S3, calling an API (application program interface) by the client of the service application system, selecting a printing template meeting the requirement, and initiating a request to the server. The requested content includes the name fileName of the selected printing template, the token corresponding to the selected printing template, and the printing device code machineCode to be used for printing the printing template, and at this time, the code sent by the API interface is as follows:
the fileName content is a template used by the service to be printed, and the server may store a plurality of printing templates (e.g., business license, food and drug administration license), and which one is to be used is specified by the parameter; the maschineCode is printed through a server, a plurality of client machines are called, parameters are required to explain which machine is processing, for example, a No. 1 machine and a No. 2 machine are simultaneously used for printing business license, and the operations of the two machines cannot be influenced mutually; the token is the unique identifier of the binding operation, the subsequent series of operations are connected in series by the parameter, and one complete process uses the same token.
It should be added that, with reference to fig. 2, before the client of the service application system calls the API interface to select a printing template meeting the requirement,
a client of the service application system calls an API (application program interface) interface and sends an instruction for opening a printing template to a server;
the server receives the instruction and calls OFFICE software to open the printing template;
the OFFICE software returns a token generated correspondingly to the opened printing template to the server;
and the server receives the token and calls the API (application programming interface) to return the instruction relationship between the printing template and the token to the client.
And S4, the server of the business application system receives the request, and modifies and stores the printing template according to the instruction data.
And S5, the service end of the service application system processes the modified printing template and returns base64 content and a PNG picture of each page to the client.
And S6, uniformly previewing and printing the returned PNG pictures by the client of the service application system.
After printing is finished, the client of the service application system calls an API (application program interface) interface and sends an instruction for closing the printing template to the server;
and the server receives the instruction, calls OFFICE software to close the printing template, and clears the cache.
Based on the bookmark operation and the form operation of the present embodiment,
(A) After the printing template is selected, with reference to fig. 3, the specific process of the business system performing bookmark updating operation to form instruction data is as follows:
a client of the business application system calls an API (application program interface) interface and sends updated bookmark contents to a server;
the server receives the updated bookmark content, calls OFFICE software to open the selected printing template, obtains a token generated by the corresponding printing template, calls the updated bookmark content and updates the printing template;
and after all bookmark updating operations are executed, processing the updated printing template so as to return the PNG picture of each page to the client.
When the above specific process is implemented, the codes sent by the API interface are as follows:
wherein token is a random character string which is consistent with the printing template selected to be opened; the bookmark is the name of the bookmark, one printing template file has a plurality of bookmarks, and the position of which bookmark the content is to be placed in must be clearly indicated; text represents text content that needs to be inserted in the print template.
(B) After the printing template is selected, the specific process of the business system for performing form updating operation to form instruction data is as follows:
a client of the business application system calls an API (application program interface) interface and sends updated table contents to a server;
the server receives the updated table content, calls OFFICE software to open the selected printing template, acquires a token generated by the corresponding printing template, calls the updated table content and updates the printing template;
and after all the form updating operations are completed, processing the updated printing template to return the PNG picture of each page to the client.
The specific implementation code of the PNG picture returned by the API is as follows:
{
token, a randomly generated uuid string,
"printName": A4 Printer name "
}
The service end returns data after operating the OFFICE software
{
"Succ":1,
"data": base64 content ",
}
wherein, token is a random character string which is consistent with that used when the printing template is opened; the printName is a printer name used at the time of printing, and this parameter may not be used (default printer);
returning to the explanation: succ represents whether the instruction is executed successfully or not, if the instruction is executed successfully, 1 is returned, otherwise, 0 is returned, and all instructions have the return of Succ; the data represents the content of the file.
In summary, the OFFICE template printing method of the unified government affair service does not need to additionally install components related to debugging, reduces the implementation workload of a business application system, solves the problem that the original printing components limit the browser, and improves the compatibility of the browser.
The foregoing has outlined rather broadly the principles and embodiments of the present invention in order that the detailed description of the invention that follows may be better understood. Based on the above embodiments of the present invention, those skilled in the art should make any improvements and modifications to the present invention without departing from the principle of the present invention, and all such modifications and modifications should fall within the scope of the present invention.
