Wherein the processor 120 may perform the steps of the method shown in fig. 2. Fig. 2 is a schematic flowchart illustrating a BT download node management method according to an embodiment of the present application, including steps S201 to S204.
Step S201: and obtaining the data block in a BT downloading mode.
Specifically, the data block includes a plurality of consecutive download blocks, and the download blocks are data units obtained by a BT download method.
For example, the data block a1 includes download blocks a1, a2, a3, a4, and a5, which are arranged in the order of a1 to a5, where the download blocks a1 to a5 are data units obtained by BT download.
Step S202: checking whether a download block in the data blocks is missing.
Specifically, integrity comparison is performed on the download blocks in the data blocks through the MD5 algorithm.
For example, the data block a1 includes download blocks a1, a2, a3, a4 and a5, and the download blocks are arranged in sequence from a1 to a 5; when the data block contains all the downloading blocks, the data block can be regarded as complete;
the download block condition in the data block further comprises: the arrangement sequence of the download blocks is not arranged according to the original arrangement mode, for example, the download blocks are arranged according to a1, a3, a5, a4 and a2 and still regarded as the data blocks are complete;
step S203: and if the download blocks in the data blocks are missing, downloading the missing download blocks in the data blocks again by using an HTTP download mode.
Specifically, the download block carries identification information.
Specifically, a corresponding HTTP new request is generated according to the identification information of the missing download block.
Further, the generated HTTP new request is sent to a server to download the missing download blocks in the data blocks.
Wherein, the downloading block missing in the data block is divided into two situations: downloading blocks are overtime downloading and missing downloading blocks are downloading.
When a certain download block does not reply to the heartbeat package within a preset time interval during downloading, judging that the download block is overtime, and the download block cannot be downloaded in a BT (bit rate BT) download mode;
for example, the data block B1 is composed of download blocks B1, B2, B3, and B4 arranged in sequence, where the download block B2 does not reply to the heartbeat packet within a preset time interval, it is determined that the download block B2 is downloading a timeout, the download block B2 with the downloading timeout is downloaded by opening a new HTTP download link, and the download block B2 with the single downloading completed is stored in the data block B1 in the sequence of B1, B2, B3, and B4;
after downloading of a certain data block is finished, comparing the data block with a source file, if a missing downloading block in the data block is found, judging that the data block is incomplete, and downloading the missing downloading block by opening a new HTTP downloading link to complete the data block;
for example, the data block C1 is composed of download blocks C1, C2, C3 and C4 arranged in sequence, and when the MD5 algorithm is compared with the original file, the download blocks C1 and C4 are found to be missing, so that the data block C1 is found to be missing, the missing download block C1 and the download block C4 are downloaded by starting a new HTTP download link, and the download blocks C1 and C4 which are downloaded separately are stored into the data block C1 in the sequence of C1, C2, C3 and C4.
And step S204, storing the data block into a local storage space.
Further, the local storage space includes, but is not limited to, storage devices such as a local disk, a removable hard disk, and a usb disk.
Specifically, when the data block is complete, the data block is stored in a local storage space from a preset cache space.
According to the download management method provided by the embodiment, the data acquisition is complete when the user carries out the download task, the condition that the download task fails due to incomplete download data is avoided, the smoothness of the download task is ensured, and network resources are saved.
As shown in fig. 3, an embodiment of the present application discloses a download management method, which includes steps S301 to S309.
Step S301: and starting to download the obtained data block by using a BT (bit rate) downloading mode.
Specifically, the data block includes a plurality of consecutive download blocks, and the download blocks are data units obtained by a BT download method.
Step S302: and storing the downloaded data block into a preset cache space.
And the preset cache space is formatted and cleared after the downloading task is finished.
Step S303: checking whether the download block in the data block is complete.
Specifically, the incomplete downloading block described in this embodiment is divided into two cases, that is, downloading block downloading timeout and downloading block data missing.
When any download block is downloaded in a BT (bit rate) download mode, heartbeat information is sent to the download block, if the download block does not reply to the heartbeat information within a preset time interval, the download block is determined to be overtime when the download failure of the missing download block is determined in the BT mode, and the download block cannot be downloaded in the BT download mode;
after any data block is downloaded in a BT (bit stream) downloading mode, comparing the data block with a source file, judging that the data block is incomplete if a downloading block is missing in the data block, and downloading the missing downloading block by opening a new HTTP (hyper text transport protocol) downloading link to complete the data block;
further, the downloaded blocks are integrity-compared using the MD5 algorithm.
Step S304: and (4) performing complete downloading on the missing downloading blocks by using an HTTP downloading mode.
Specifically, a complementary downloading is carried out on the missing downloading blocks by using an HTTP downloading mode, wherein a corresponding HTTP new request is generated according to the identification information of the missing downloading blocks;
and sending the generated HTTP new request to a server to download the missing download blocks in the data blocks.
Step S305: and judging whether the complete data block is continuous or not.
Specifically, the complete data block is compared with the source file through the MD5 algorithm;
for example, the complete data block D1 includes download blocks D1, D2, D3, D4, and after the data block D1 is downloaded, the download blocks are arranged in the order D2, D1, D4, D3, and the data block D2 corresponding to the complete data block D1 in the source file includes download blocks D1, D2, D3, D4, and the arrangement order is D1, D2, D3, D4; in the comparison process, if the arrangement order of the download blocks in the data block D1 is found to be inconsistent with the arrangement order of the download blocks in the corresponding data block D2, it is determined that the data block D1 is a discontinuous data block, and step S306 is performed on the data block D1.
Step S306: the non-contiguous data blocks are ordered.
According to the example shown in step S305, if the arrangement order of the download blocks D1, D2, D3 and D4 in the data block D1 is not consistent with the arrangement order of the download blocks D1, D2, D3 and D4 in the data block D2 corresponding to the data block D in the source file, the download block arrangement order in the data block D1 is sorted according to the arrangement order of the download blocks in the source file corresponding to the data block D2, so that the download blocks in the data block D1 are ensured to be the same as the download block arrangement order in the data block D2.
Step S307: and judging whether all the data blocks are completely downloaded.
Specifically, if all the data blocks are completely downloaded, step S307 is performed, and if all the data blocks are completely downloaded, step S301 is returned to continue to perform the downloading task and execute the method described in this embodiment until all the data blocks are completely downloaded.
For example, the source file E includes data blocks X, Y, and Z, after the downloading is completed, by detecting that the download file E1 lacks the data block X, it is determined that all the data blocks are not downloaded completely, and at this time, the step S301 is returned to download the missing data block X again until all the data blocks in the source file E are downloaded completely.
Step S308: and obtaining a complete download file and storing the complete download file in a preset cache space.
Step S309: and storing the obtained download file into a local storage space.
Specifically, the obtained downloaded file is complete and continuous, and the complete and continuous file is stored in the local storage space from the cache space, so that the random writing possibility is greatly reduced, and the service life of the computing hardware equipment is prolonged.
According to the download management method provided by the embodiment, the obtained data blocks are complete and continuous, and the complete and continuous data blocks are stored in the preset cache and then are written into the local storage space together, so that the possibility of random writing when the data blocks are written into the local storage space is reduced, computer hardware equipment is protected, the data writing time is shortened, and the service life of the computer hardware equipment is prolonged.
Secondly, by the BT and HTTP cooperative downloading method and device, the fact that data blocks are completely and continuously acquired when a user carries out a downloading task can be guaranteed, downloading smoothness is improved, the situation that the downloading task fails due to the fact that downloading data are incomplete is avoided, the smoothness of the downloading task is guaranteed, and network resources are saved.
