[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1

[0027] like Figure 1 As shown, an embodiment of the present invention provides a file uploading method, which is applied to a server, and the method includes:

[0028] S101, obtaining fingerprint information of a file to be uploaded, where the fingerprint information is generated according to the file content of the file to be uploaded;

[0029] In this step, the fingerprint information can be obtained by encrypting the file content according to an encryption algorithm. The encryption algorithm can be an MD5 encryption algorithm. In this case, the fingerprint information of the file to be uploaded can be called the MD5 value of the file to be uploaded.

[0030] The server obtains the fingerprint information of the file to be uploaded, which may include: after the server temporarily stores the file to be uploaded, calculating the fingerprint information of the file to be uploaded according to an encryption algorithm, and in a subsequent step, if it is determined that the server already has a target file with the same file content as the file to be uploaded, then deleting the cached file to be uploaded from the server; or, the fingerprint information of the file to be uploaded is calculated by the user, and the server obtains the fingerprint information calculated by the user. In this way, compared with the previous method, it can avoid occupying the server bandwidth when uploading the file to be uploaded.

[0031] S102, using the fingerprint information as a keyword to set a distributed lock;

[0032] In this step, the distributed lock includes a keyword (key), and the distributed lock is set with the fingerprint information as the key of the distributed lock. For example, the distributed lock is set with the MD5 value of the file to be uploaded as the key of the distributed lock. In this way, if multiple user terminals upload the same file at the same time, only one user terminal can obtain the distributed lock. Other users need to wait for the user who has obtained the lock to release the distributed lock when operating. When other users obtain the lock, the current file has been uploaded, which can effectively prevent the scenario of uploading the same file under high concurrency.

[0033] S103, judging whether there is a target file with the same file content as the file to be uploaded on the server side according to the fingerprint information;

[0034] In this step, the fingerprint information of the file to be uploaded can be compared with the fingerprint information of the file stored in the server. When the generation rule of the fingerprint information of the file to be uploaded is the same as the generation rule of the fingerprint information of the file on the server, the file whose fingerprint information is the same as the fingerprint information of the file to be uploaded is the target file.

[0035] S104: If yes, updating the upload parameters of the target file according to the characteristic information of the file to be uploaded;

[0036] In this step, when the target file exists, that is, the file to be uploaded already exists on the server, there is no need to repeatedly upload the file to be uploaded. It is only necessary to save the characteristic information of the file to be uploaded to the server. In this way, the storage space of the server can be greatly saved.

[0037] Specifically, the upload parameters of the target file may be updated according to the characteristic information of the file to be uploaded; the characteristic information of the file to be uploaded may include the file name, file size, file fingerprint information, and uploader information; the upload parameters of the target file may include characteristic information of each upload and the total number of uploads; at this time, Figure 2 As shown, updating the upload parameters of the target file according to the characteristic information of the file to be uploaded may include:

[0038] S1041, creating an association relationship between the characteristic information of the file to be uploaded and the storage address of the target file;

[0039] S1042: Add 1 to the total number of upload times corresponding to the target file.

[0040] In this embodiment, since the file names, file sizes, and uploaders of other files to be uploaded that have the same file content as the target file may be different from the corresponding information of the target file, creating an association between the characteristic information of the files to be uploaded and the storage address of the target file can facilitate uploaders of other files to be uploaded to query, obtain, or delete the target file based on the characteristic information of the files to be uploaded that they uploaded.

[0041] The target file is provided with a total upload count, through which the total upload count of files with the same content as the target file can be counted. In this way, when the user terminal requests to delete a file to be uploaded that it has uploaded, the server terminal only needs to reduce the total upload count corresponding to the target file by 1 according to the deletion instruction of the file to be uploaded, without physically deleting the target file.

[0042] Optionally, the server may be provided with a relational database. In this case, the association relationship created in the above steps and the total number of uploads corresponding to the target file may be stored in the relational database.

[0043] S105: Release the distributed lock.

[0044] In this step, after the server completes processing the file to be uploaded, it releases the distributed lock, and other users who upload the same file can continue to upload the file. This can effectively prevent the same file from being uploaded in high concurrency situations, and can also avoid congestion when uploading large files.

[0045] The file uploading method provided by the embodiment of the present invention obtains the fingerprint information of the file to be uploaded, and the fingerprint information is generated according to the file content of the file to be uploaded; the distributed lock is set with the fingerprint information as a keyword; according to the fingerprint information, it is judged whether there is a target file with the same file content as the file to be uploaded on the server; if so, the upload parameters of the target file are updated according to the characteristic information of the file to be uploaded; and the distributed lock is released. In this way, before storing the file to be uploaded, it can be judged whether the server already has a target file with the same content. In the case that the server already has a target file with the same content, the file to be uploaded is no longer repeatedly saved, and only the characteristic information of the file to be uploaded is recorded, which solves the problem of storing multiple copies of the same file in the server and occupying the server hard disk resources, and realizes file sharing by multiple users; in addition, before processing the file to be uploaded, a distributed lock is set according to the fingerprint information of the file to be uploaded, and after the processing of the file to be uploaded is completed, the distributed lock is released, so that the same file can be effectively prevented from being uploaded in high concurrency, and the situation of storing multiple copies of the same file is further avoided.

[0046] Optionally, in the above embodiment, when it is determined that there is no target file on the server whose file content is the same as the file content of the file to be uploaded, before releasing the distributed lock, the method also includes: obtaining the total number n of shards of the file to be uploaded; receiving the 1st to nth shard data of the file to be uploaded; integrating the shard data to generate an integrated file; generating fingerprint information of the integrated file based on the file content of the integrated file; determining whether the fingerprint information of the integrated file is the same as the fingerprint information of the file to be uploaded; and if so, saving the integrated file.

[0047] In this embodiment, when the size of the file to be uploaded is large, the file to be uploaded is uploaded in pieces, which can solve the problem that the large file size affects the upload or download speed, and can alleviate the problem that the large file size occupies the server bandwidth and causes the server to process other requests slowly. For example, the size of each piece of data can be controlled to about 5 megabytes.

[0048] In addition, after the fragment data are integrated, the present embodiment also compares the fingerprint information of the integrated file with the fingerprint information of the file to be uploaded to prevent errors in the integration of the fragment data. When it is determined that the fingerprint information of the integrated file is different from the fingerprint information of the file to be uploaded, that is, an error occurs when the fragment data is integrated, the integrated file can be deleted and the user end is notified of an error in uploading the file to be uploaded.

[0049] Optionally, in the above embodiment, after saving the integrated file, the method may further include: creating an association relationship between characteristic information of the file to be uploaded and the storage address of the integrated file, the characteristic information of the file to be uploaded including file name, file size, file fingerprint information, and uploader information; setting the total number of uploads corresponding to the integrated file to 1.

[0050] In this embodiment, since the integrated file is integrated from the fragmented data of the file to be uploaded, the integrated file stored by the server is equivalent to storing the content of the file to be uploaded. At this time, it is only necessary to record the association between the characteristic information of the file to be uploaded and the storage address of the integrated file, so that the uploader of the file to be uploaded can view, call or delete the integrated file according to the characteristic information of the file to be uploaded. The characteristic information of the file to be uploaded can also include the number of fragments when uploading the file to be uploaded.

[0051] Since the server does not have other files with the same content as the integrated file, the integrated file is uploaded for the first time to the server, and therefore the total number of uploads corresponding to the integrated file is set to 1.

[0052] like Figure 3 As shown, optionally, the receiving of the 1st to nth fragment data of the file to be uploaded; integrating each of the fragment data to generate an integrated file; may include: when the first fragment data of the file to be uploaded is received, creating an integrated file and writing the first fragment data into the integrated file; according to the fragment identifier of the fragment data, writing the other received fragment data into the integrated file in sequence.

[0057] Optionally, the device also includes an integration unit, which is used to: obtain the total number n of fragments of the file to be uploaded; receive the 1st to nth fragment data of the file to be uploaded; integrate each of the fragment data to generate an integrated file; generate fingerprint information of the integrated file based on the file content of the integrated file; determine whether the fingerprint information of the integrated file is the same as the fingerprint information of the file to be uploaded; if so, save the integrated file.

After saving the integrated file, the method further includes: Creating an association relationship between characteristic information of the file to be uploaded and the storage address of the integrated file, wherein the characteristic information of the file to be uploaded includes file name, file size, file fingerprint information, and uploader information; The total number of uploads corresponding to the integrated file is set to 1.

2. A file uploading device, characterized in that: Applied to the server, the device comprises: An acquisition unit is used to acquire fingerprint information of a file to be uploaded, wherein the fingerprint information is generated according to the file content of the file to be uploaded; the encryption algorithm is an MD5 encryption algorithm; the fingerprint information of the file to be uploaded is called the MD5 value of the file to be uploaded; A setting unit is used to set a distributed lock using the fingerprint information as a keyword; wherein the distributed lock is set using the MD5 value of the file to be uploaded as the key of the distributed lock; if multiple users upload the same file at the same time, only one user obtains the distributed lock, and other users need to wait for the user who obtains the lock to release the distributed lock when operating. When other users obtain the lock, the current file has been uploaded, which effectively prevents the same file from being uploaded in high concurrency; A judging unit, configured to judge whether there is a target file having the same file content as the file to be uploaded on the server side according to the fingerprint information; Wherein, judging whether there is a target file with the same file content as the file to be uploaded on the server side according to the fingerprint information includes: Compare the fingerprint information of the file to be uploaded with the fingerprint information of the file stored in the server, and when the generation rule of the fingerprint information of the file to be uploaded is the same as the generation rule of the fingerprint information of the file on the server, the file whose fingerprint information is the same as the fingerprint information of the file to be uploaded is the target file; an updating unit, configured to update the upload parameters of the target file according to the characteristic information of the file to be uploaded; The releasing unit is used to obtain the total number n of fragments of the file to be uploaded; receive the first to nth fragment data of the file to be uploaded; integrate the fragment data to generate an integrated file; wherein receiving the first to nth fragment data of the file to be uploaded; integrating the fragment data to generate an integrated file includes: Upon receiving the first fragment data of the file to be uploaded, creating an integrated file and writing the first fragment data into the integrated file; and writing the other received fragment data into the integrated file in sequence according to the fragment identifiers of the fragment data; Generate fingerprint information of the integrated file according to the file content of the integrated file; determine whether the fingerprint information of the integrated file is the same as the fingerprint information of the file to be uploaded; if so, save the integrated file; and release the distributed lock; Before releasing the distributed lock, the method further includes: obtaining the total number n of shards of the file to be uploaded; receiving the 1st to nth shard data of the file to be uploaded; integrating the shard data to generate an integrated file, and generating fingerprint information of the integrated file according to the file content of the integrated file; judging whether the fingerprint information of the integrated file is the same as the fingerprint information of the file to be uploaded; if so, saving the integrated file; after integrating the shard data, comparing the fingerprint information of the integrated file with the fingerprint information of the file to be uploaded to prevent errors in integrating the shard data; when judging that the fingerprint information of the integrated file is different from the fingerprint information of the file to be uploaded, that is, an error occurs when integrating the shard data, the integrated file is deleted and the user end is notified that the upload error of the file to be uploaded occurs; Wherein, after temporarily storing the file to be uploaded, the server calculates the fingerprint information of the file to be uploaded according to the encryption algorithm, and in a subsequent step, if it is determined that the server already has a target file with the same file content as the file to be uploaded, the cached file to be uploaded is deleted from the server; or, the fingerprint information of the file to be uploaded is calculated by the user end, and the server obtains the fingerprint information calculated by the user end; The characteristic information of the file to be uploaded includes the file name, file size, file fingerprint information, and uploader information; the upload parameters of the target file include the characteristic information of each upload and the total number of uploads; The updating unit comprises: A creation subunit is used to create an association relationship between the characteristic information of the file to be uploaded and the storage address of the target file; A counting subunit is used to add 1 to the total number of uploads corresponding to the target file; wherein the server is provided with a relational database, and the created association relationship and the total number of uploads corresponding to the target file are stored in the relational database; Wherein, the counting subunit is also used for: According to the deletion instruction of the file to be uploaded, the total upload times corresponding to the target file is reduced by 1; Wherein, the device further comprises: A creating unit, used to create an association relationship between the characteristic information of the file to be uploaded and the storage address of the integrated file, wherein the characteristic information of the file to be uploaded includes the file name, file size, file fingerprint information, and uploader information; The counting unit is used to set the total upload times corresponding to the integrated file to 1.
