Detailed Description
In the prior art, the paper invoice is printed by calling internal logic after invoicing by relying on third-party software and equipment, but for users who only need to perform simple operations such as single printing or previewing on existing invoice data at other front ends, the learning cost and the operation complexity of the users are increased, and the invoice printing efficiency and convenience are reduced. In order to overcome the technical problem, the application provides the printing method easy to call by the front end, the relevant printing operation can be realized by calling by the front end, and the printing efficiency is improved.
The embodiment of the application discloses an invoice printing method, and as shown in fig. 1, the method may include the following steps:
step S11: and acquiring a printing service request sent by a WEB front end and/or a client through a POST interface.
In this embodiment, the print service request sent by the WEB front end and/or other clients is obtained through the POST interface, and specifically, the print service request may be obtained through the POST interface provided by the local print service. For example, as shown in fig. 2, when the print service (i.e., NPrintService) is started, the WEB front end and/or the client sends a print service request through the POST interface to call the print service.
Step S12: and calling a printing program based on the printing service request to execute the printing operation corresponding to the printing service request.
In this embodiment, after receiving the print service request, a print program is called according to the print service request, so that the print operation corresponding to the print service request is executed by running the print program. For example, as shown in fig. 2, after the WEB front end and/or other clients send print service requests to invoke print services, the print services invoke corresponding print logic methods according to the print service requests to process corresponding print jobs.
Step S13: and acquiring a printing execution result and sending the printing execution result to the corresponding WEB front end and/or the client.
In this embodiment, after the printing program is run to implement the corresponding print task, the printing program returns a print processing result to the printing service, and the printing service sends the print processing result to the corresponding WEB front end and/or the client, so as to implement printing or previewing of the target file. Therefore, the printing result statistics can be facilitated for the user. It can be understood that, the embodiment provides a logic structure convenient for the invocation of the WEB front end and/or the client, and the printing operation can be realized through the invocation of the WEB front end and/or the client, and can be the printing of a paper invoice, and can also be the printing of other files; and the printing is convenient and fast, the method is suitable for the existing printing scenes needing to print data, and can be adapted to the calling of different front ends.
In this embodiment, the invoice printing method may further include: receiving a printing instruction of a target invoice sent by the WEB front end and/or the client; wherein the print instructions comprise a print instruction based on a command prompt and a print instruction based on a link address; the link address is an address determined by inquiring the href attribute of the label a in the registry; and operating the printing program according to the printing instruction to print the target invoice. The printing operation is realized by directly calling a printing program by receiving a printing instruction based on a command prompt, which can be a CMD command, and a printing instruction based on a link address, which are sent by a WEB front end and/or a client. For example, as shown in fig. 2, the WEB front end and/or the client may also directly call the printing program to implement the printing operation by sending a CMD command or accessing a connection address obtained by using an href attribute of an a tag of a hypertext language (HTML) tag; specifically, the connection address may be obtained by querying a corresponding key value preset in the registry. However, the print result cannot be fed back to the WEB front end and/or the client by the two types of instruction calling methods.
As can be seen from the above, in this embodiment, a print service request sent by a WEB front end and/or a client is obtained through a POST interface; then calling a printing program based on the printing service request to execute the printing operation corresponding to the printing service request; and finally, acquiring a printing execution result and sending the printing execution result to the corresponding WEB front end and/or the corresponding client. Therefore, the printing service requests sent by different front ends and other local clients can be directly obtained through the POST interface, and then the printing program is called according to the printing service requests to execute the printing operation, so that the WEB front end and other clients can conveniently call the printing tool to preview and print the invoice, third-party software and equipment are not needed, the usability and operability of the printing function are improved, and the invoice printing efficiency is improved.

step S21: receiving a printing service request sent by a WEB front end and/or a client by using a POST (POST on the fly) interface through running a locally installed printing service executable file; the printing service executable file comprises a printing service program created based on a Windows communication development platform and a RESTful architecture.
In this embodiment, a POST interface may be provided to the WEB front end and/or the client by running the print service executable file installed locally, so that the print service request sent by the WEB front end and/or the client is received through the POST interface; the printing service executable file comprises a printing service program created based on a Windows communication development platform and a RESTful architecture. It is understood that the print client will automatically run the print service executable file to start the print service after installation, or may start the print service by double-clicking the print service executable file under the installation target. Therefore, the printing service program created based on the Windows communication development platform and the RESTful architecture can provide a POST interface capable of realizing printing function calling for a WEB front end and/or a client.
Step S22: and acquiring target metadata of a target program set through reflection technology according to the printing service request so as to call the printing program.
In this embodiment, after receiving a print service request sent by a WEB front end and/or a client by accessing the POST interface, the print service obtains target metadata in a target program set by using a program set reflection technology, so as to call the print program to implement a print function.
Step S23: and acquiring a printing execution result and sending the printing execution result to the corresponding WEB front end and/or the client.
For the specific process of the step S23, reference may be made to corresponding contents disclosed in the foregoing embodiments, and details are not repeated here.
In the embodiment, a print service request sent by a WEB front end and/or a client is received by a POST interface through running a locally installed print service executable file; the printing service executable file comprises a printing service program established based on a Windows communication development platform and a RESTful architecture; then, target metadata of the target set is acquired by the reflection technique in accordance with the print service request to call the printing program. Therefore, by running the printing service program created based on the Windows communication development platform and the RESTful framework, a POST interface capable of realizing printing function calling can be provided for the WEB front end and/or the client, so that a corresponding printing service request is received, the printing program is called through program set reflection, printing operation is realized, the WEB front end and/or the client can be called to realize printing related operation, extra application and external dependence do not need to be started according to the single printing requirement of a user, and the usability of the printing related operation is greatly enhanced.
