In accordance with an embodiment of the present invention, there is provided an embodiment of a method for file upload, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than that described herein.
Alternatively, in this embodiment, the method for uploading the file may be applied to a hardware environment formed by the terminal 10 and the server 30 shown in fig. 1, and the terminal may establish a connection with the server through a network. Wherein, the terminal and the server can be provided with a processor.
Such networks include, but are not limited to: a wide area network, a metropolitan area network, or a local area network. Preferably, the network is a local area network.
The terminal can be a personal computer, a mobile terminal and an intelligent terminal, for example, the terminal can be a smart phone, a PDA, a tablet computer and the like.
According to an embodiment of the present invention, a method for uploading a file is provided, as shown in fig. 2, the method may include the following steps:
step S202: acquiring a received file to be uploaded;
step S204: judging whether the data capacity of the file to be uploaded is larger than a capacity threshold value or not;
step S206: if the data capacity of the file to be uploaded is larger than a capacity threshold value, dividing the file to be uploaded into a plurality of data blocks;
step S208: and uploading the plurality of divided data blocks to a server in parallel.
By adopting the embodiment, when the data capacity (namely the size of data) of the file to be uploaded on the web page is larger than the capacity threshold value, namely the file to be uploaded is a large file, the file to be uploaded is divided into the data blocks, and the data blocks are uploaded to the server in parallel.
Step S202 in the above embodiment may acquire the received file to be uploaded through a web page.
The data capacity in the above embodiment is: the size of the data.
In an alternative embodiment, the capacity threshold in the above embodiments may be set as a fixed threshold, the fixed threshold may be a preset capacity threshold, and the fixed threshold may correspond to a file format of a file to be uploaded, for example, the fixed thresholds set for the video file and the text file may be different.
In another optional embodiment, the threshold value is dynamically adjusted according to the uploading adjustment parameter; or, the uploading adjustment parameter includes at least one of a current network state, an uploading time period and a file format to be uploaded.
The transmission efficiency can be further improved by dynamically adjusting the capacity threshold according to different uploading adjustment parameters. For example, the dynamic threshold dynamically adjusted based on the current network state can avoid the problem of low transmission efficiency caused by data division according to the fixed threshold under the extremely poor network condition.
Specifically, a user can select a file to be uploaded at the front end of the web through a form or other selection modes, after a terminal where the web page is located obtains the file to be uploaded received through the web page, the size of the file to be uploaded is obtained, whether the data capacity of the file to be uploaded is larger than a capacity threshold value is judged, if the data capacity of the file to be uploaded is larger than the capacity threshold value, the file to be uploaded is divided into a plurality of data blocks, and the divided data blocks are uploaded to a server in parallel. Alternatively, the capacity threshold may be a fixed 20M, or may be dynamically adjusted according to the upload adjustment parameter.
Optionally, if the data capacity of the file to be uploaded is not greater than the capacity threshold, the file to be uploaded may be uploaded in a default uploading manner of the web page, for example, in a serial manner, or through an API (application programming interface) set by HTML.
As shown in fig. 3, this embodiment can be implemented by the following steps:
step S302: and the user selects the file to be uploaded which needs to be uploaded through the web page.
The user can enter a file list of the terminal where the web page is located through buttons of 'browse' or 'select file' of the web page and the like, select a file to be uploaded from the file list, and display attribute information (such as attribute information of name, size and the like) of the file to be uploaded on the web page of the terminal.
Step S304: the web page obtains the size of the file to be uploaded.
Step S306: and judging whether the file to be uploaded is a large file.
Specifically, the method can be realized by judging whether the data capacity of the file to be uploaded is larger than a capacity threshold value; if the data capacity of the file to be uploaded is greater than the capacity threshold, determining that the file to be uploaded is a large file, and executing step S310; if the data volume of the file to be uploaded is not greater than the volume threshold, it is determined that the file to be uploaded is not a large file, and step S308 is executed.
Step S308: and uploading the file according to the default mode of the web page.
The default mode may be serial upload or upload through an API interface.
Step S310: and dividing the file to be uploaded into a plurality of data blocks.
Step S312: and uploading the plurality of divided data blocks to a server in parallel.
The implementation manners of step S308 and step S310 are the same as the implementation manners of step S206 and step S208 in the above embodiments, and are not described herein again.
In the above embodiment of the present invention, dividing the file to be uploaded into a plurality of data blocks may include: partitioning files to be uploaded according to a preset number of parts to obtain data blocks of the preset number of parts; or partitioning the file to be uploaded according to the preset data capacity to obtain a plurality of data blocks.
Alternatively, when the file to be uploaded is divided, the data capacity of the divided data blocks may be equal or unequal. Specifically, the file to be uploaded can be divided into a fixed number of data blocks, for example, the file to be uploaded can be divided into 512 fixed data blocks, and if the file to be uploaded is divided by the scheme, the size of each divided data block can be smaller than a preset threshold (optionally, the preset threshold can be 8M); the file to be uploaded may also be divided into a plurality of data blocks according to a fixed size, for example, the file to be uploaded is divided according to a division manner of 8M data blocks, for example, the size of the file to be uploaded is 4G, and the file to be uploaded may be divided into 512 data blocks according to the fixed size of 8M (4G/8M is 512).
In the embodiment, after the user selects the large file to be uploaded on the web page, the web page obtains the size of the file to be uploaded, then blocks the file according to the fixed size to obtain a plurality of data blocks, and uploads the data blocks to the server in parallel, so that the uploading speed can be increased in a parallel uploading manner.
According to the above embodiment of the present invention, uploading the plurality of partitioned data blocks to the server in parallel may include: setting a number for each data block based on the sequence of the data blocks in the file to be uploaded, and acquiring the sending sequence of the data blocks according to the sequence of the numbers; the method comprises the steps of sequentially determining a plurality of data blocks to be uploaded in a sending sequence from a first data block in the sending sequence through a data block selection window, and uploading the plurality of data blocks to be uploaded to a server in parallel after the plurality of data blocks to be uploaded are determined each time until all the plurality of data blocks are uploaded to the server, wherein the width of the data block selection window is used for representing the number of the data blocks to be uploaded.
The width of the data block selection window can be determined based on the number of data blocks which are allowed to be uploaded simultaneously in each parallel uploading.
Specifically, sequentially determining a plurality of data blocks to be uploaded in a transmission sequence through the data block selection window may include: after N data blocks to be uploaded determined through the current data block selection window are uploaded to a server in parallel, response information returned by the server is received; and if the response information indicates that the server receives M continuous data blocks to be uploaded starting from the first data block to be uploaded in the N data blocks to be uploaded, moving the current data block selection window backwards by the positions of the M data blocks along the sending sequence to determine that the data block in the current data block selection window is the data block to be uploaded next time. Wherein N is a natural number greater than 1, and M is a nonnegative integer less than or equal to N. Alternatively, N may be 4 or 5.
In the above-described embodiment, a number may be set for each data block based on the order of the plurality of data blocks in the file to be uploaded, for example, from 1 to 512. Determining a transmission sequence of the plurality of data blocks according to the sequence from front to back, wherein the data blocks can be represented by numbers in the transmission sequence. And sequentially determining a plurality of data blocks to be uploaded in the sending sequence through a data block selection window from the first data block in the sending sequence, and uploading the plurality of data blocks to be uploaded to the server in parallel after determining the plurality of data blocks to be uploaded each time until the plurality of data blocks are sent to the server.
Specifically, after four to-be-uploaded data blocks determined by the current data block selection window are uploaded to the server in parallel, response information returned by the server is received, and if the to-be-uploaded data blocks already sent are less than the maximum number of data blocks allowed to be sent at the same time (corresponding to the width of the data block selection window in the above embodiment), the allowed number of data blocks are sent at the same time immediately.
For example, the maximum number of data blocks allowed to be transmitted simultaneously is 5, after data blocks to be uploaded with numbers 1, 2, 3, 4 and 5 are transmitted simultaneously in parallel, response information of the server is received, and if the response information shows that: data block 2 receives the acknowledgement, then data block number 4 receives the acknowledgement, then data block number 1 receives the acknowledgement. After the data block with the number 1 receives the response, the data blocks with the numbers 2 and 4 already receive the response, and the data blocks with the numbers 3 and 5 do not receive the response, because the maximum 5 data blocks are allowed to be simultaneously transmitted, the data blocks with the numbers 6 and 7 can be immediately transmitted after the data blocks with the numbers 1 and 2 have already been received.
The above embodiments are described in detail below with reference to fig. 4 to 8.
It should be noted that the filled boxes in fig. 5 to 8 are data blocks that have been sent and have received responses; the shaded boxes in the figure are data blocks that have been transmitted but have not received a reply, and the blank boxes are data blocks that have not been transmitted.
As shown in fig. 4, numbers from 1 to 12 may be set for each data block based on the order of the data blocks in the file to be uploaded (only data blocks numbered 4, 6, and 8 are labeled in fig. 4, but each number in the figure represents a data block), a transmission sequence of the data blocks is determined in the order of numbers from front to back, and fig. 4 shows an alternative representation of the transmission sequence, where each number in the transmission sequence represents a corresponding data block. Starting from the first data block (for example, the data block numbered 1 in fig. 4) in the transmission sequence, sequentially determining a plurality of data blocks to be uploaded in the transmission sequence through the data block selection window, and uploading the plurality of data blocks to be uploaded to the server in parallel after determining the plurality of data to be uploaded each time.
As shown in fig. 5, if the width of the data block selection window is 4 (i.e. the number of data blocks allowed to be transmitted at the same time is 4), the data block to be uploaded is determined from the data block numbered 1 in the transmission sequence, the data block to be uploaded for the first time is determined to be the data block numbered 1-4 through the data block selection window, and if the data blocks numbered 1, 2, 3 and 4 have been transmitted and have received a response (in this case, N is 4 and M is 4), the data block selection window slides backwards (to the right) by the position of four data blocks, that is, the data block to be uploaded in the current data block selection window is numbered 5-8, the data blocks numbered 5-8 are uploaded to the server in parallel, and the response information indicates that the server receives the data blocks numbered 6 and 7. The server can generate a response signal after receiving a data block to be uploaded, the response signal carries the number of the received data block to be uploaded to indicate that the server receives the numbered data block to be uploaded, and the response information comprises one or more response signals.
As shown in fig. 6, after receiving the response signal of the data block numbered 5, since the data blocks numbered 6 and 7 have already received the response signal, that is, at this time, the server receives 3 consecutive data blocks to be uploaded starting from the first data block in the four data blocks to be uploaded (at this time, N is 4, and M is 3), the current data block selection window slides to the right (back) by the positions of the 3 data blocks (corresponding to 3 cells in the transmission sequence), and then the next multiple data to be uploaded transmitted in parallel are multiple data in the current data block selection window: the data blocks numbered 8-11 are transmitted in parallel at the same time as the data block numbered 8 is already transmitted, the data blocks numbered 9, 10, 11.
As shown in fig. 7, after receiving the response signal of the data block numbered 10, since the data block numbered 8 does not respond, that is, the server determined by the response information receives zero consecutive data blocks to be uploaded from the first data block in the four (8-11) data blocks to be uploaded (in this embodiment, N is 4, and M is 0), the data block selection window no longer slides to the right, and no data block is transmitted.
As shown in fig. 8, after receiving the data block response with the number of 8, the server identified by the response information receives 1 consecutive data block to be uploaded from the first data block of the four (8-11) data blocks to be uploaded (in this case, N is 4, and M is 1), the current data block selection window slides to the right by 1 cell, and the data block with the number of 12 is transmitted.
In the above embodiment, a plurality of data blocks to be uploaded are sequentially determined through the data block selection window, and after a plurality of data blocks to be uploaded are determined each time, the plurality of data blocks to be uploaded are sent in parallel until the front end sends all the data blocks, and after the front end receives all the data block responses of the background, the data can be considered to have been sent.
Optionally, before sequentially determining the data blocks to be uploaded in the transmission sequence through the data block selection window, the width of the data block selection window may be dynamically adjusted according to the acknowledgement information, where the acknowledgement information includes: the server generates an adjustment instruction based on the cache capacity and/or the network congestion parameter, and/or an adjustment instruction generated by the terminal for receiving the file to be uploaded.
In the above embodiment of the present invention, while uploading a plurality of data blocks to be uploaded to a server in parallel, the method may further include: and simultaneously sending the serial numbers of the data blocks to be uploaded to the server.
After uploading the plurality of data blocks to be uploaded to the server in parallel, the method may further include: the server receives a plurality of data blocks to be uploaded in parallel; after each data block to be uploaded is received, generating a response signal of the data block to be uploaded, and sending the response signal to a terminal for receiving a file to be uploaded, wherein the response signal carries the number of the data block to be uploaded and is used for indicating a server to receive the numbered data block to be uploaded; and writing the received data block to be uploaded into a target file.

According to the above embodiment of the present invention, after the data blocks are obtained by splitting, the web front end numbers each data block in order, for example: from 1 to 512. After determining the sending sequence according to the sequence of the numbers, the plurality of data blocks are sent to the server in parallel according to the scheme in the above embodiment, and each time one data block is sent, the number of the data block is sent to the server at the same time. The server receives the data blocks in parallel, and immediately returns a response signal to the web front end after receiving each data block, wherein the response parameter of the response signal contains the number of the received data block, if the data block (the number is smaller than the number of the currently received data block) in front of the currently received data block is received in sequence, that is, the data block and the received data blocks with continuous numbers are written into a target file together, for example, the data blocks with the numbers 3, 4 and 6 are received, at this time, after receiving the data block with the number 2, the data with the numbers 2, 3 and 4 are written into the file, and after receiving the data block with the number 5, such as the data block with the number 6, the data block with the number 5 is written into the file together; otherwise, the data block is cached, and the data blocks are written into the target file together after all the previous data blocks are received.
In the above embodiment, after the front end receives the response signal from the server, the number in the response signal is obtained, if the data blocks before the number have all received the response, the calculation is started from the next number of the number, and if the data blocks that have been transmitted are less than the maximum number of data blocks that are allowed to be transmitted at the same time, the allowed number of data blocks are transmitted at the same time immediately.
