Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the method for creating a file according to an embodiment of the present invention includes the following steps:
s101, creating a first file, wherein the first file is used for storing a file to be downloaded; in this embodiment, taking video on demand as an example, when a user sends an on demand request during video on demand, the system starts to create a file for storing a video file to be downloaded;
s102, acquiring tail data of a file to be downloaded; the index information of a general video file is at the tail of the file, before downloading the file, the tail data of the file to be downloaded can be acquired firstly, and can be temporarily stored in a memory of a system and not written into a hard disk temporarily; the size of the last data of the file to be downloaded can be set to different values according to the requirement, and the size of the index information of the video file generally does not exceed 2 Mbytes, so that the data of 2 Mbytes at the end of the file to be downloaded can be generally obtained.
S103, judging whether the file to be downloaded is a large file; after the system establishes the download link through the network according to the request of the user, a file for storing the download information is generally established, the file comprises the information such as the size of the file to be downloaded, and the size of the file to be downloaded can be judged according to the content in the file. Setting a reference value for comparison can be realized, for example, 100M, 200M, etc. can be set according to needs. Generally, a file with more than 100 megabytes can be regarded as a large file, and if the reference value can be set to be 100M, the file to be downloaded is regarded as the large file when the file to be downloaded is more than 100M; when the file to be downloaded is less than 100M, the file is considered to be a small file.
S104, if the file to be downloaded is a small file, sequentially writing the file to be downloaded into a first file; that is, if the file is a small file, the file to be downloaded is sequentially written into the created file according to the normal downloading sequence, as in the first file in this embodiment, because the file is not large, even if the index information is at the end, the index information of the file can be quickly acquired.
And S105, if the file to be downloaded is a large file, creating a temporary file, and writing the tail data into the temporary file, wherein the size of the temporary file generally does not exceed 2 megabytes, which is based on the size of the index information of the video file, and the size of the temporary file in the embodiment is 2M, that is, the tail data of the file to be downloaded, namely 2M, can be stored. The optimized large file can be created by creating the temporary file, when a user requests to access the video file, if the video file is large, the index information of the video file can be quickly obtained by firstly obtaining the temporary file, and therefore the video file can be quickly and directly played or dragged to a certain playing position in the downloading process.
S106, after writing the tail data into the temporary file, sequentially downloading the file to be downloaded to the first file;
s107, directly combining the data in the temporary file when the tail data is downloaded;
further, the method for creating a file according to the embodiment of the present invention further includes step S108, after the file downloading operation is completed, the temporary file may be deleted, so as to save the storage space.
As shown in fig. 3, the file creating system according to the embodiment of the present invention mainly includes a first file creating unit 10, a first file 20, an end data obtaining unit 30, a judging unit 40, a downloading unit 50, a temporary file creating unit 60, a temporary file 70, and a temporary file deleting unit 80. Wherein,
a first file creating unit 10, configured to create a first file 20, where the first file 20 is used to store a file to be downloaded; still taking video on demand as an example, when a user sends an on demand request during video on demand, the file creation system starts to create a first file for storing a video file to be downloaded.
A last data acquiring unit 30 for acquiring last data of the file to be downloaded; the last data is generally retrieved no more than 2 mbytes.
A judging unit 40, configured to judge whether a file to be downloaded is a large file; after establishing a download link through a network according to a user's request on demand, a general file creation system establishes a file for storing download information, the file includes information such as the size of the file to be downloaded, and the size of the file to be downloaded can be determined according to the content in the file. Typically files above 100 megabytes can be considered large files.
The temporary file creating unit 60 is configured to create a temporary file 70 when the file to be downloaded is a large file, and write the last data into the temporary file 70 through the downloading unit 50, where the size of the temporary file 70 generally does not exceed 2 mbytes; when a user requests to access a video file, if the video file is large, the index information of the video file can be quickly acquired by acquiring the temporary file 70, so that the video file can be quickly and directly played or dragged to a certain playing position in the downloading process.
A downloading unit 50, configured to, when the determination result of the determining unit 40 is that the file to be downloaded is a small file, sequentially write the files to be downloaded into the first file 20; or, when the judgment unit 40 judges that the file to be downloaded is a large file, the last data is written into the temporary file 70, and then the file to be downloaded is sequentially downloaded to the first file 20.
Further, in the file creating system according to the embodiment of the present invention, the downloading unit 50 is further configured to directly merge the data in the temporary file 70 into the first file 20 when downloading the last data of the large file; the system further comprises a temporary file deleting unit 80, configured to delete the temporary file 70 after the downloading unit 50 merges the data in the temporary file 70 into the first file 20, because after the downloading of the file to be downloaded is completed, the user can directly perform the video on demand locally, the response speed is fast, and the access speed is increased without using the temporary file 70. Deleting the temporary file 70 can clean up the storage space in time.
