Existing step includes：The image data acquiring unit external request uses http protocol, by GET request mode download pictures,
ID or the path of picture is obtained from request, is then looked into from image data cache module, database and MFS file system successively
Ask picture whether there is, do not exist with regard to failed download, if there is the binary code stream the download pictures that then read picture.
8. a kind of online quick visit of the method for the online quick access queries picture that realizes as described in claim 1 to 7 is arbitrary
The system for asking inquiry picture, it is characterised in that：Including：Transmission module, image data preserving module, data processing mould on image data
Block, image data cache module and picture display module, the data processing module also include image data query unit, picture
Data determining unit, image data receiving unit and image data transmitting element, on the image data, transmission module obtains picture
Essential information data, using MD5 algorithm obtain Image ID, on the image data, transmission module is according to Image ID successively from picture
With the presence or absence of simultaneously download pictures, the data processing module collects the big of the picture of the download to data cache module inquiry picture
Rim space distribution, distribution of color, image blur and saturation infromation, and it is aobvious to be calculated the items of the picture to be shown
Show parameter scores score value；
Wherein, the data processing module also includes that image data query unit, image data judging unit, image data are received
Unit and image data transmitting element；
The image data query unit external request uses http protocol, obtains picture by HEAD request method and believes substantially
Breath, first parses picture path from message body, inquires about pictorial information according to path from the image data cache module；
The image data judging unit judges whether to inquire image data, if inquiring image data, by picture number
According to being transferred to the image data receiving unit；If less than image data, the image data query unit is according to road for inquiry
The picture is inquired about with the presence or absence of the mark in file system from data cache module in footpath；If there is no file system in mark prompting
System, then return and do not inquire pictorial information；If there is file system in mark prompting, the image data cargo tracer primitive root
Go in database, to inquire about fileinfo according to picture path；If fileinfo can be inquired, Query Result is returned, and will figure
Piece information is written in the image data cache module；If fileinfo can not be inquired, MFS file system is gone according to path
Picture Binary Resources are obtained in system；If picture Binary Resources are not got, picture is not existed file system mark
Will is write in the image data cache module, if there are picture Binary Resources are got, then parse picture Binary Resources,
Picture essential information is got, by essential information successively write into Databasce and the image data cache module, by pictorial information
Return.
