step S101, after the SFTP service is started, the remote file server is connected with a system server.

In step S101 of the embodiment of the present specification, the SFTP command is executed on the premise that the SFTP service is started, and then the remote file server is connected to the system server by using the configured user name and password through the SFTP command.

Step S102, storing the files in cache regions of the system servers, wherein each cache region of the system server corresponds to one cache path.

In step S102 of this embodiment, the file is first stored in a cache on the system server after being uploaded.

And step S103, uploading the files in the cache region of the system server to the cache regions of the remote file servers by calling an SFTP command according to the cache paths corresponding to the files in the cache region of the system server, wherein each cache region of each remote file server corresponds to one cache path.

And step S104, if the page corresponding to the file needs to be loaded, downloading the file from the cache region of the remote file server to the cache region of the system server by calling an SFTP command according to the cache path corresponding to the file in the cache region of the remote file server.

In step S104 in this embodiment of the present description, if a user needs to load a certain page, the user needs to download a file stored in the cache area of the remote file server to the cache area of the system server, so that the content of the file can be displayed on the page, for example, when the file is a picture, the user can only view the picture from the cache area of the remote file server to the cache area of the system server.

The embodiment of the specification stores the files on the remote file server in a unified manner, and establishes connection with the remote file server through the system server, so that the files are encrypted and mutually transmitted safely, and the operating pressure of the system server is reduced.

Corresponding to the first embodiment of the present specification, fig. 2 is a schematic flowchart of a file management method based on SFTP provided in the second embodiment of the present specification, where the following steps may be executed by a file management system in the embodiment of the present specification, and the specific steps may include:

step S201, after the SFTP service is started, the remote file server is connected with the system server.

In step S201 of the embodiment of the present specification, the SFTP command is executed on the premise that the SFTP service is started, and then the remote file server is connected to the system server by using the configured user name and password through the SFTP command.

Step S202, storing the file in a cache area of the system server, wherein the cache area of each system server corresponds to one cache path.

In step S202 of this embodiment, the file is first stored in a cache on the system server after being uploaded.

Step S203, uploading the files in the cache area of the system server to the cache areas of the remote file servers by calling an SFTP command according to the cache paths corresponding to the files in the cache area of the system server, wherein each cache area of the remote file server corresponds to one cache path.

Step S204, inserting record data into the file, and setting the state of the record data to be 0.

In step S204 of the embodiment of the present specification, a state of 0 may indicate that the cache area uploaded to the remote file server has been uploaded. The recorded data of the file can be seen in table 1.

TABLE 1

Step S205, after the form is submitted and saved, change the state of the recorded data to 1.

In step S205 of the embodiment of the present specification, the state may also be a save state of the current file, where 0 is uploaded and not saved, and 1 is saved. The form submission save may be a save of a file.

An embodiment of the present application further provides a file management medium based on SFTP, in which computer-executable instructions are stored, where the computer-executable instructions are configured to:

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functionality of the units may be implemented in one or more software and/or hardware when implementing the present application.

As will be appreciated by one skilled in the art, embodiments of the present invention may be provided as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.

It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.

Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data.
