Fig. 2 is the first flow diagram for the document down loading method that this specification one or more embodiment provides, Fig. 2 In method can be executed by the file scanning device in Fig. 1, as shown in Fig. 2, this method at least includes the following steps:

S201 is detected and is uploaded the target text that policy uploads file to be uploaded with the presence or absence of file under specified store path Part；

Wherein, above-mentioned specified store path can be file upload side and file reception side and make an appointment and upload files to finger The specified path for determining the SFTP server of special line, it is first when file upload side needs a certain file being transferred to file reception side This document is uploaded under specified store path by first file upload side, and then file reception side downloads under specifying store path from this This document；For example, being directed to Third-party payment mechanism payment transaction related to bank's progress, need to carry out in many ways after the completion of payment The application scenarios that fund is calculated, file to be uploaded are fund clearing information, the money that Third-party payment mechanism will need bank to check Gold clearance information is uploaded under specified store path, and banking institution downloads the fund clearing information under specified store path and goes forward side by side Row verification；

Wherein, since file to be uploaded has certain file size, text to be uploaded is uploaded to since the file to be uploaded Part upload, which finishes, needs certain uplink time, during the upload of file to be uploaded, the attribute information of the file destination of upload with The variation of uplink time and constantly update, after detecting file destination, supporting paper upload side has started upper transmitting file；

If it exists, then S202 is executed, the current attribute information of file destination is obtained according to prefixed time interval；

Specifically, in the case where detecting specified store path there are after file destination, with a certain trace interval by pair File destination carries out multiple timing and scans to obtain its current attribute information, wherein the current attribute information can be file destination Newest file size can also be the newest modification time of file destination；

S203 judges whether file to be uploaded uploads and finishes according to the current attribute information of file destination；

Wherein, after file upload side uploads file to be uploaded, the attribute information of file destination is remained unchanged, i.e., The attribute information that present scan obtains is identical as the attribute information that last scanning obtains, at this time the file size of file destination with The file size of file to be uploaded is identical, the file content for including in file destination and the file content for including in file to be uploaded It is identical, therefore, text to be uploaded can be determined in conjunction with the attribute information of the file destination scanned according to prefixed time interval Whether part, which uploads, finishes；

If so, executing S204, file reception side's downloading object file is triggered；Wherein, in the upper transmitting file in file upload side Later (after detecting the file destination for existing under specified store path and being uploaded for file to be uploaded for the first time) and file Recipient download file before (i.e. determine file uploaded finish before), believed by the attribute of timing scan file destination Breath finishes to judge whether file upload side uploads, after the completion of determining that file upload side uploads file to be uploaded, text Part recipient downloads file under specified store path and uploads the file destination that policy uploads file to be uploaded, can guarantee The integrality of file download, and downloading object file is triggered in the first time for determining that file upload is completed, it can guarantee text The timeliness of part downloading.

In this specification one or more embodiment, after file upload side starts upper transmitting file, and file reception side is opened Begin to determine before downloading file by the current attribute information of Multiple-Scan file destination, and in conjunction with the current attribute information After file to be uploaded has uploaded, the file destination is just downloaded, to realize that file uploads under the first time triggering completed File destination is carried, reaches under the premise of the integrality for the file destination that confirmation has uploaded, executes file download operation in time Purpose can ensure file download timeliness and file download integrality simultaneously in this way.

Wherein, judging whether file uploads the process finished, Multiple-Scan is needed to obtain the current attribute of file destination Information is based on the current attribute information of file destination after scanning obtains current attribute information every time whether to determine file Upload finishes, and after determining that file uploads, stops scanning, after determining that file does not upload, continues timing scan, is based on This, as shown in figure 3, current attribute information of the above-mentioned S203 according to file destination, judges whether file to be uploaded uploads and finishes, tool Body includes:

S2031, judges whether the current attribute information of file destination meets the preset termination condition of scanning, wherein the attribute Information can be file size, can also be filemodetime, be also possible to file size and filemodetime, either The continually changing attribute information of alternative document upload procedure；Corresponding, which can be attribute information guarantor Hold it is constant, i.e., when determining that attribute information that present scan obtains and the attribute information that last scanning obtains remain unchanged, Determine that the current attribute information of file destination meets the preset termination condition of scanning；

It is finished if so, determining that file to be uploaded has uploaded, specifically, in the current attribute information for determining file destination After meeting the preset termination condition of scanning, file upload operation is completed in supporting paper upload side, and the file of file destination is big at this time File small identical as the file size of file to be uploaded, including in the file content and file to be uploaded for including in file destination Content is identical, can guarantee the integrality of file destination；

Otherwise, the step that above-mentioned S202 obtains the current attribute information of file destination according to prefixed time interval is continued to execute Suddenly, specifically, after the current attribute information for determining file destination is unsatisfactory for the preset termination condition of scanning, supporting paper is uploaded Side not can guarantee the integrality of file destination also in upper transmitting file, needs to continue waiting for the upload of file upload side and finishes.

Wherein, above-mentioned current attribute information may include: file size and/or filemodetime, it can according to mesh The file size of mark file judges whether file uploads completion, can also judge file according to the filemodetime of file destination Whether upload complete, can also be judged according to two parameters of file size and filemodetime of file destination file whether on It passes and completes；Specifically, judging whether the file size of file destination remains unchanged, and/or judge the file modification of file destination Whether the time remains unchanged；Whether can be remained unchanged by judging the file size of file destination, or by judging mesh Mark file filemodetime whether remain unchanged, or the file size by judging file destination whether remain unchanged with And whether filemodetime remains unchanged, to determine whether file uploads completion；

Further, it is contemplated that according to the attribute information of some time interval timing scan file destination, and be based on the category Property information judges whether file uploads the executing subject finished and can be file reception side, can also be independently of file reception side Individual file scanning device.Wherein, in order to minimize the treatment process for adjusting file reception side, and in view of file connects Debit may have multiple, therefore, file scanning device can be set in the equipment independently of file reception side；

It, can be using the side that file name is marked for file scanning device independently of the situation of file reception side Formula downloads file to trigger file reception side in time, by taking attribute information is filemodetime as an example, is based on this, as shown in figure 4, The realization process of document down loading method specifically:

Wherein, after determining that file upload side completes file upload, triggering file reception side starts to download the mode of file, It can be in such a way that file name is marked, can also be by the way of sending prompting download information, for adopting Used in the case where file is marked file name after having uploaded is determined, file reception side is also required to timing scan acquisition The file name of file destination, so that after detecting that file name becomes preset format, timely downloading object file is based on This, for file reception side, in the case where detecting specified store path, there are files to upload policy in file institute to be uploaded After the file destination of biography, further includes:

S205, file reception side obtain the file name of file destination according to the second time interval, wherein second time Interval can be identical as first time interval, can also be different；

S206, file reception side judge whether the file name of file destination meets preset format；If it is not, then continuing to execute S205, if so, downloading object file；

Corresponding, above-mentioned S204 triggers file reception side's downloading object file, specifically includes:

If file reception side detects that the file name of file destination meets preset format, S2041, file reception are executed Square downloading object file；Specifically, file scanning device is after setting preset format for the file name of file destination, file Recipient will test file name and meet preset format.

Wherein, it is contemplated that judge whether file uploads the process finished according to the current attribute information of file destination every time, Need by present scan to file attribute information be compared with the attribute information that scans of last time, therefore, for for the first time The case where scanning file destination needs to record the file attribute information of file destination, and arrives for non-first scan The case where file destination, illustrates the last file attribute information scanned for having recorded the file destination, will record at this time File attribute information be updated to the file attribute information that present scan arrives, this is based on, as shown in figure 5, detecting specified deposit After uploading the file destination that policy uploads file to be uploaded there are file under storage path, further includes:

S207 judges whether there is the attribute information recorded for file destination, wherein for first scan to target The case where file, judging result be there is no, and be directed to non-first scan file destination attribute information the case where, judging result To exist；

If it does not exist, then S208 is executed, obtains and record the attribute information of file destination, and using attribute information as needle To the attribute information of file destination first record, and continues to execute above-mentioned S202 and obtain file destination according to prefixed time interval The step of current attribute information, file upload side starts to upload file to be uploaded to specified store path at this time.

It is corresponding, the case where for non-first scan to file destination, illustrate that the last time for having recorded the file destination sweeps The file attribute information recorded is updated to the file attribute information that present scan arrives at this time by the file attribute information retouched, Based on this, after determining that file to be uploaded does not upload, further includes:

S209 is directed to the attribute information that file destination is recorded according to the current attribute information update got, and continues The step of above-mentioned S202 obtains the current attribute information of file destination according to prefixed time interval is executed, specifically, mesh will be directed to The file attribute information that has recorded of mark file is updated to the newest file attribute information that present scan arrives, so as to will be updated Judge whether current attribute information meets preset termination scanning as subsequent for the file attribute information that file destination is recorded The benchmark of condition.

It is corresponding, judge whether file uploads the process finished for based on file attribute information, above-mentioned S203 is according to mesh The current attribute information for marking file, judges whether file to be uploaded uploads and finishes, specifically include:

For the current attribute information got every time, judges the current attribute information and be directed to what file destination was recorded Whether attribute information is consistent；

If consistent, it is determined that file to be uploaded, which has uploaded, to be finished；If inconsistent, it is determined that file to be uploaded has not uploaded Finish.

In a specific embodiment, it is 10:34 point that file upload side, which starts the time of upper transmitting file, specifies store path For ABC/pay/20181108/alipay_ABC_pay.txt, for the prior art, due to can not accurately predict in advance When file, which uploads, finishes, in order to guarantee file download integrality, by way of delaying predetermined file download time, and agreement 11:30 starts to download file, but actually may 10:44 file uploaded completion, lead to that there are file download poor in timeliness Problem；In order to guarantee file download timeliness, by way of arranging the file download time in advance, agreement 11:46 starts to download File, but file upload progress may be affected for some reason, actually 10:50 file just uploads completion, leads to not The problem of guaranteeing file download integrality；

In order to combine file download timeliness and file download integrality, this specification one or more embodiment In, the process of file download specifically includes:

After uploading the file destination that policy uploads file to be uploaded there are file in the case where detecting specified store path, The current attribute information of file destination is obtained according to prefixed time interval；And for the current attribute information got every time, sentence Whether the current attribute information that breaks changes, and after determining that the current attribute information of file destination does not change, determines File upload finishes；

Wherein, default with first for the process of the attribute information of file scanning device multiple timing scanning file destination Time interval be 5 minutes for, specifically:

If the time point of scanning file is 2018-11-09 10:30 for the first time, file upload side does not have started upload at this time Therefore file destination is not present under specified store path in file；

If the time point of second of scanning file is 2018-11-09 10:35, file upload side has started to upload text at this time Part, therefore, there are file destinations under specified store path, and obtain the current attribute information of file destination, and file size is 3000KB, the last modification time of file are 2018-11-09 10:34:10, record the attribute information of file destination；

If the time point of third time scanning file is 2018-11-09 10:40, there are mesh under specified store path at this time File is marked, and obtains the current attribute information of file destination, file size 4100KB, the last modification time of file is 2018- 11-09 10:39:57, the current attribute information and last time scan recorded attribute information (file size 3000KB, text The last modification time of part is 2018-11-09 10:34:10) it is inconsistent, then supporting paper, will be for target text still in upper crossing The attribute information that part is recorded is updated to the current attribute information, and (file size 4100KB, the last modification time of file are 2018-11-09 10:39:57)；

If the time point of the 4th scanning file is 2018-11-09 10:45, there are mesh under specified store path at this time File is marked, and obtains the current attribute information of file destination, file size 4200KB, the last modification time of file is 2018- 11-09 10:44:29, the current attribute information and last time scan recorded attribute information (file size 4100KB, text The last modification time of part is 2018-11-09 10:39:57) it is inconsistent, the attribute information recorded for file destination is updated For the current attribute information (file size 4200KB, the last modification time of file are 2018-11-09 10:44:29)；

If the time point of the 5th scanning file is 2018-11-09 10:50, there are mesh under specified store path at this time File is marked, and obtains the current attribute information of file destination, file size 4200KB, the last modification time of file is 2018- 11-09 10:44:29, the current attribute information and last time scan recorded attribute information (file size 4200KB, text The last modification time of part is 2018-11-09 10:44:29) unanimously, supporting paper, which has uploaded, to be finished；

Preset format is set by the file name of file destination, for example, by the title of file destination again name are as follows: ABC/ Pay/20181108/alipay_ABC_pay_2018apilayinsure.txt (specified format symbol be old file name+year+ Apilayinsure+ file suffixes).

It should be noted that the first prefixed time interval can be reduced in order to further increase the timeliness of file download, Or the first prefixed time interval is determined with reference to the multiple relation factors for influencing file uploading speed, so that it is guaranteed that on file After biography side's completion file uploads in the shortest time, determine that the current attribute information of file destination meets preset termination scan stripes Part.

Wherein, for the process of the file name of file reception side's multiple timing scanning file destination, trace interval For the second prefixed time interval, which can be less than or equal to above-mentioned first prefixed time interval, specifically Are as follows:

If the time point for scanning file is 2018-11-09 10:33, file upload side does not have started transmitting file at this time, Therefore, it is not processed；

If the time point for scanning file is 2018-11-09 10:40, there are file destinations under specified store path, but The file name of file destination is non-designated format (specified format is [year+apilayinsure] symbol), is not processed, In, 10:33 to 10:40 can pass through Multiple-Scan；

If the time point for scanning file is 2018-11-09 10:51, there are file destinations under specified store path, and The file name of file destination is specified format (specified format is [year+apilayinsure] symbol), then downloading object file, Wherein, 10:40 to 10:51 can pass through Multiple-Scan.

Further, in order to improve the scanning precision of file attribute information, need to preset file attribute information Trace interval is based on this, before above-mentioned S202 obtains the current attribute information of file destination according to prefixed time interval, Further include:

Determine that the file of file to be uploaded uploads feature, wherein it includes: that file uploads time-consuming, text that this document, which uploads feature, At least one of part uploading bandwidth, file size；

Feature is uploaded according to the file for the file to be uploaded determined, determines and file to be uploaded is uploaded for scanning needle File destination attribute information used in prefixed time interval.

Wherein, when determining the prefixed time interval of attribute information of timing scan file destination, with reference on influence file The multiple relation factors for passing speed, can be improved the scanning precision of file attribute information in this way, further increase file download Timeliness；Specifically, uploading feature by file includes for file uploads time-consuming, file uploading bandwidth and file size, in advance If time interval calculation formula are as follows: R=b₁x+b₂y+b₃Z, wherein R indicates prefixed time interval, b₁It is time-consuming to indicate that file uploads Weight coefficient, b₂Indicate the weight coefficient of file uploading bandwidth, b₃Indicate that the weight coefficient of file size, x indicate to be directed to file Upload the first numerical value that time-consuming occurrence is converted to, y indicate that the occurrence for file uploading bandwidth is converted to the Two numerical value, z indicate the third value that the occurrence for file size is converted to, wherein calculate in prefixed time interval public In formula, since the unit of multiple relation factors is different, it is therefore desirable to according to preset rules by the specific value of each relation factor into The unified conversion of row, then the numerical value after conversion is substituted into formula and obtains prefixed time interval.

In a specific embodiment, as shown in fig. 6, giving the multiterminal interaction schematic diagram in document down loading method, tool Body includes:

S601, file upload direction and store path knit stitch are specified to upload file destination to file to be uploaded, wherein to upper Transmitting file starts to be uploaded to file upload to be uploaded and finish to need certain uplink time, during the upload of file to be uploaded, on The file size and filemodetime of the file destination of biography are constantly updated with the variation of uplink time；

S602, file scanning device detect and upload policy to file institute to be uploaded with the presence or absence of file under specified store path The file destination of upload；
