Abstract
With the development of the internet technology in today's world, people can acquire network shared resources quickly and easily. More and more people begin to download resources through the internet. However, during resource downloading, downloading may be interrupted or stopped due to multiple accidents such as accidental cutting off of power supplies, interruption of networks and restart of systems caused by operating system failures. Those reasons can cause interruption of downloading, but a user finds that originally downloaded data disappear and is required to download resources again when downloading the resources again and feels that all previous efforts are wasted. In order to solve the problem, the invention discloses an HTTP (hypertext transfer protocol)-based method for realizing continuous file transfer from breakpoints. According to the method, downloading tasks are completed instead of being started all over again by the aid of some redirection mechanisms in the network protocol.
Description
Technical field
The present invention relates to a kind of implementation method based on http protocol breakpoint transmission file.The invention belongs to field of computer technology.
Background technology
Along with the development of world today's Internet technology, people more and more rely on the Internet.Be not difficult to find, present people online has not been singly that open any browser carrys out browsing page, but starts the various resources downloaded on the Internet.But, downloading resource from the Internet is a process, in the process of downloaded resources, probably there will be a lot of fortuitous events download is interrupted or stops, such as unexpected power-off, unexpected suspension or operating system failure causes system restart etc.These reasons all can cause the interruption of downloading, and when user wishes to find when continuing downloaded resources that the original data downloaded have not been present in, must restart to download.Downloaded to the resource of 99% soon, but owing to going offline suddenly, all that has been achieved is spoiled, and that dejected probably everybody lives through.Breakpoint transmission just effectively can solve such problem, its task is when downloading stopping, record the information of current download, and utilize some redirection mechanisms in procotol to continue downloading task and need not do again from the beginning, namely continue to download from the place of file interruption last time download.
Summary of the invention
In order to bring convenience to the download of numerous Internet users, enabling user continue to download the file interrupting because of various reasons last time downloading, invention describes a kind of implementation method based on http protocol breakpoint transmission file.Concrete steps are as follows:
Step 1: user enters system, fills in the association attributes of necessary downloaded resources in newly-built task.
Step 2: system sends HTTP message request, and then server returns response message according to request, confirms that the errorless thread that just starts starts downloaded resources, and the data stored in buffer memory is finally stored into object store path.
Step 3: the newly-built downloading task of user, in time having downloaded a part, has interrupted downloading, and then the task that beginning has just been interrupted, then original downloading task can continue to download, instead of again downloads.
Embodiment
Embodiment one
Use MyEclipse 8.6 as developing instrument, use special database management tools MySQL on market to set up the database required for system.
But 1. judge whether to carry out breakpoint transmission: when user newly set up a downloading task and choose download file deposit path time, first judge whether this file exists under this catalogue.If there is no, then set up new downloading task to download; If existed, also need to judge that this file judges that whether file destination is complete: if the file of complete download, system can point out user whether will cover download; If just downloaded the file of part, then carry out breakpoint transmission.
2. arrange breakpoint: analyze the temporary file downloaded, all temporary files of traversal file destination, arrange the starting position of breakpoint transmission, i.e. the length of each temporary file, and to server request from file reading.The naming method of temporary file is: file destination name+" _ "+numbering.
3. resume: arrange local file write start byte, and connect from last time transmitted breakpoint succession write.
In addition to the implementation, the present invention can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of application claims.
Claims (3)
1. analyze the temporary file downloaded, all temporary files of traversal file destination, arrange the starting position of breakpoint transmission.
2. the naming method of temporary file is: file destination name+" _ "+numbering.
3., after local file write start byte is set, transmitted breakpoint succession write from last time.
