The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Aiming at the technical problems mentioned in the background art, the embodiment of the application provides a file downloading method, and particularly referring to fig. 1, a flowchart of the file downloading method is provided in the embodiment of the invention. Before describing the implementation steps of the method, a file downloading system to which the method is applicable is first described, as shown in fig. 2, which is a schematic view of an application scenario in a specific embodiment of the present invention. In the file downloading system according to the embodiment of the present invention, the client may be a web page or the like corresponding to the browser in the file downloading process, and the server may be the end storing the file in the file downloading process.
Next, specific execution procedures of each module in the related file download system will be described.
Specifically, referring to fig. 1, the file downloading method is executed by a client, and includes the following steps:
step 101, when file information of at least one file to be downloaded is greater than a preset threshold in the process of downloading the file, generating a file dividing instruction according to first file information corresponding to the first file and the preset threshold, and sending the file dividing instruction to a server.
The file dividing instruction is used for indicating the server to divide the first file into a plurality of file blocks according to the first file information and a preset threshold, wherein the first file is any one of at least one file to be downloaded.
In the file downloading process, when the file information to be downloaded is greater than a preset threshold, a file dividing instruction needs to be generated according to the first file information corresponding to the first file and the preset threshold. In the downloading process of the file, the file information of the corresponding file to be downloaded, that is, when the occupied memory size of the file exceeds a preset threshold, can be defined as a large file.
In general, the definition of a large file may be that an individual file exceeds Gb, or that package download is performed on all files, or that a number of files have sizes exceeding Gb may be referred to as a large file, and of course, in the embodiment of the present invention, the specific numerical value of the preset threshold is not limited, and may be determined by a person skilled in the art according to practical situations.
In addition, another explanation is provided for the preset threshold, in the preset threshold, the client can smoothly download the file to be downloaded, and when the preset threshold is exceeded, the file is downloaded, so that the condition that the background art is crashed or the node is turned off may occur.
Therefore, when the generation and file division instructions are performed, the generation needs to be performed together according to the first file information and the preset threshold value, so that the service end can be ensured to divide the first file into file blocks which are smaller than the preset threshold value when the file division instructions are executed.
Step 102, response information fed back by the server is obtained, wherein the response information comprises indication information that the server finishes dividing the first file.
Step 103, downloading each file block according to the response information, so as to finish downloading all the first files.
Illustratively, after sending the file division instruction to the server side, waiting for response information of the server side, wherein the response information includes indication information that the first file division is completed.
After the response information is acquired, the corresponding divided file blocks are downloaded from the server side, and the first file is divided into a plurality of file blocks, so that the problems of downtime and downloading interruption possibly occurring in the downloading process due to overlarge files are avoided.
On the basis of the above embodiment, the response information further includes identification information corresponding to each file block and first total identification information, where the identification information is used to characterize an order in which the file blocks are divided, and the first total identification information is used to characterize identification information of the first file, and the method further includes:
respectively downloading each file block, identification information corresponding to the file block and first total identification information;
obtaining second total identification information of all the file blocks according to the identification information of each file block;
when the second total identification information is consistent with the first total identification information, sequentially combining each file block in the order of the identification information to obtain a first file.
The response information includes identification information corresponding to each file block and first total identification information, where the identification information is an identity of each file block, and an order of the corresponding file blocks in all file blocks may be determined according to the identification information.
And respectively downloading all the file blocks, corresponding identification information and first identification information, and combining the file blocks according to the identification information after the downloading of all the file blocks is completed, so as to obtain a complete first file.
In this case, the first file is divided and recombined, so as to ensure that the combined first file corresponds to the first file of the server, and avoid errors in the downloading or combining process. The first file which is combined at this time can obtain total identification information, namely second total identification information, according to the identification information of each file block, and if the second total identification information is consistent with the first total identification information, the first file which is obtained by combining the corresponding identification information at this time is identical with the first file of the server.
When the second total identification information is inconsistent with the first total identification information, an error occurs in the downloading process or the combining process, and in this case, in order to further eliminate the possibility of the error, all files need to be downloaded again, and the judgment is continued according to the file blocks after the downloading again.
When an error occurs after the re-downloading, the file dividing instruction can be regenerated and sent to the server, or the file dividing instruction can be directly re-sent, the corresponding file blocks and other information can be re-downloaded after the response information is obtained, and the corresponding file blocks can be directly re-downloaded, so that the downloading of the first file can be completed.
Preferably, in the embodiment of the present invention, the identification information and the first total identification information may both be marked in the form of hash codes, as shown in fig. 3, which is a schematic diagram of marking the file blocks with hash codes, and a specific implementation process may be that the first file is a hash code total value, corresponding to the first total identification information, the hash code total value is divided into N file blocks with a preset threshold value as an interval on the basis of the hash code total value, each file block 512bit, each hash corresponding to the file block has a start value and an end value, and the end value of the last file block corresponds to the start value of the next file block, so that all the file blocks may be combined, and then the hash code total value (final result hash value) may be obtained according to the combined file blocks.
In another optional embodiment, the file dividing instruction further includes identification information and a binding relationship between the identification information and the file blocks, so that the server side binds the file blocks and the corresponding identification information according to the binding relationship between the identification information and the file blocks after dividing the file blocks.
When the file division instruction includes the identification information and the binding relation between the identification information and the file blocks, the server associates the corresponding file blocks with the identification information according to the binding relation in the file division instruction after the first file division is completed, wherein the specific binding relation can be embodied in the form of a table or a similar Map set, and the specific form is not limited.
In the foregoing embodiment, after the server side completes dividing the first file, each file block is downloaded according to the response information, which specifically includes: and respectively downloading a plurality of file blocks by using a plurality of preset service nodes according to the response information until all the file blocks are downloaded.
For example, when downloading the file blocks, in order to increase the downloading speed, a multithreaded polling mode may be adopted for downloading at a plurality of preset service nodes, and in the downloading process, factors such as the sequence among the file blocks are not required to be considered, so long as downloading of all the file blocks is completed.
According to the file downloading method, in the process of downloading files, when file information of at least one file to be downloaded is larger than the preset threshold value, the fact that the file to be downloaded is too large at the moment and possibly has downtime is indicated, and according to the situation, a client generates a file dividing instruction according to a first file, corresponding first file information and the preset threshold value, and sends the file dividing instruction to a server, so that the server can divide the first file into a plurality of file blocks according to the file dividing instruction; further, after the indication message of the completion of the division of the first file fed back by the server is obtained, each file block is downloaded respectively, so that the downloading of the first file is completed. Therefore, the risk of downtime in the process of downloading large files and the risk of forced shutdown by the network transit node under the condition of long time and large transmission quantity are avoided.
Corresponding to the above method embodiment, the embodiment of the present invention further provides a file downloading method, as shown in fig. 4, executed by a server, where the method includes the following steps:
step 401, obtaining a file division instruction sent by a client, where the file division instruction includes first file information and a preset threshold.
Step 402, dividing the first file into a plurality of file blocks according to the first file information and a preset threshold.
Step 403, when the first file division is completed, sending response information to the client, where the response information is used to indicate an indication message that the first file division is completed.
The method includes the steps that after a file dividing instruction sent by a client is obtained, a first file is divided according to first file information in the file dividing instruction and a preset threshold value, and corresponding information is fed back to the client after the division is completed, so that a corresponding file block is downloaded by a subsequent client according to the response information.
In an optional embodiment, the response information further includes identification information corresponding to each file block and first total identification information, where the identification information is used to characterize an order in which the file blocks are divided, and the first total identification information is used to characterize identification information of the first file, so that the subsequent client verifies the first file obtained after the file blocks are combined according to the identification information.
If the response information further includes the identification information of each file block and the first total identification information corresponding to the first file, the description server not only divides the first file according to the file division instruction, but also identifies the divided file blocks, so that the corresponding file blocks can be identified according to the identification after the client downloads, and the problem of confusion of the file blocks is avoided.
In an alternative embodiment, when the file division instruction further includes identification information and a binding relationship between the identification information and the file blocks, after dividing the first file into the plurality of file blocks according to the file division instruction, the method further includes:
and binding the file blocks and the identification information corresponding to the file blocks according to the binding relation between the identification information and the file blocks, so that the client combines the file blocks according to the binding relation between the identification information and the file blocks to obtain a first file.
Illustratively, when the identification information and the binding relation between the identification information and the file blocks are included in the file dividing instruction, the divided file blocks can be bound with the corresponding identification information in the process of dividing the first file.
As shown in fig. 5, a flowchart of one embodiment of the above method is shown, specifically, for a case of batch downloading, an interface is required to be requested from a server, a file directory and a corresponding file of the server of the file to be downloaded are obtained from the server, and a file tree corresponding to the file directory and the corresponding file is generated according to the file directory and the corresponding file; the client can download files in a multithreaded parallel manner according to a file tree in a plug-in mode, the problem that popup window inquiry is frequently received when a large number of files are downloaded can be avoided by adopting the plug-in mode to download the files, particularly, a download interface of an access server can download a plurality of files in parallel, when a large file is encountered, if the size of a file formed by each file block after the downloading is inconsistent with the size of the file corresponding to the server, the local failure is written or the call of the download interface fails, the corresponding files (all the file blocks) are downloaded again until the downloading is completed, and the program is ended.
The downloading interface and the file block division and the corresponding identification information are requested from the server side by the following modes:
the process of verifying the second total identification information with the first total identification information may be implemented in the following manner:
in this way, when the file dividing instruction is obtained in the process of downloading the file, the first file can be divided into a plurality of file blocks according to the file dividing instruction; after the division is finished, response information is timely fed back to the client, so that after the client obtains an indication message fed back by the server and used for finishing the division of the first file, each file block is downloaded respectively, and the downloading of the first file is finished.
