In the related technology, a file transmission mode in the cloud service is mainly to transmit a file which needs to be uploaded by a user at the front end to a back-end server, and then upload the file to a designated file server through the back-end server, so that the file is uploaded through the transfer of the back-end server. However, this way of transferring reduces the efficiency of file transfer.

In order to solve technical problems in the related art, embodiments of the present invention provide a file transmission method, apparatus, server, system, and storage medium. Any file transmission device provided by the embodiment of the invention can be integrated in a corresponding server. The server comprises a first server and a second server, wherein the first server and the second server can be independent physical servers, can also be a server cluster or a distributed system formed by a plurality of physical servers, and can also be cloud servers for providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (content delivery network) and big data and artificial intelligence platforms. For example, the first server is a cloud server providing a cloud database, such as a file server, the file server may be a MonIO file server, and the like, and the second server is a cloud server providing a cloud service, such as a cloud application server.

Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a file transmission method according to an embodiment of the present invention, where the application scenario includes a first server such as a file server, a second server such as a cloud application server, and a terminal, where the terminal includes but is not limited to a smart phone, a Pad, a wearable device, a robot, a smart television, a smart air conditioner, a smart car device, a Personal Computer (PC), a conference terminal, and the like.

Specifically, as shown in fig. 1, the first server is in communication connection with the second server, the second server is in communication connection with the terminal of the user, and after the terminal obtains the target fragment signature link, the terminal may also be in communication connection with the first server through the target fragment signature link.

Referring to fig. 2 and fig. 3, fig. 2 is a simplified flowchart of a file transmission method according to an embodiment of the present invention, fig. 3 is a flowchart of a file transmission method according to an embodiment of the present invention, the file transmission method according to an embodiment of the present invention includes steps 101 to 104, and specifically, referring to fig. 3 with reference to fig. 2, the method steps in fig. 3 are described below.

Step 101, receiving a file fragment transmission request from a second server, and obtaining file information, user information, transmission information of each file to be transmitted in a plurality of files to be transmitted corresponding to the file fragment transmission request, and fragment information of a fragment to be transmitted corresponding to each file to be transmitted.

In this embodiment, please continue to refer to fig. 2, where the received file fragment transmission request is generated by the terminal and transmitted to the first server via the second server, and the specific process includes: the method comprises the steps of firstly obtaining file information of each file to be transmitted and user information of the file to be transmitted in a plurality of files to be transmitted corresponding to file transmission instructions through a terminal, then generating target file summary information (unique MD5 value) of each file to be transmitted by using a summary algorithm such as an MD5 algorithm, and then transmitting the MD5 value of each file to be transmitted to a second server. After receiving the MD5 value, the second server detects whether the MD5 value exists, and returns a first detection result to the terminal (the first detection result represents a detection result whether the MD5 value of each to-be-transmitted file exists in the second server), and after receiving a first detection result representing that the MD5 value does not exist in the second server, the terminal performs fragmentation processing on each to-be-transmitted file, for example, fragments data of each to-be-transmitted file is performed in a data size of 5M/fragment mode (finally, a fragment to be transmitted which does not reach 5M is also used as a to-be-transmitted fragment), obtains fragmentation information of each to-be-transmitted file and each to-be-transmitted fragment, and continues to generate target file digest information (unique MD5 value) of each to-be-transmitted fragment by using an MD5 algorithm. Then the terminal sends the MD5 value of each fragment to be transmitted to the second server for detection, so as to obtain a second detection result returned by the second server (the second detection result represents a detection result of whether the MD5 value of each fragment to be transmitted exists in the second server), and when the MD5 value of the fragment to be transmitted does not exist in the second server, then the transmission information of each file to be transmitted is generated, for example, the MD5 value of the fragments to be transmitted in each file to be transmitted is in the proportion of the number of the fragments to be transmitted in the second server to the total fragments to be transmitted, then generating a file fragment transmission request according to the fragment information, the user information, the file information and the transmission information of the corresponding fragment to be transmitted (i.e. the fragment to be transmitted which is not transmitted), and sending the file fragment transmission request to a second server so that the second server sends the file fragment transmission request to the first server.

The file information includes file size, file name, file type, etc., and the file type may include, but is not limited to, jpg,. doc,. xlsx,. mp4,. wmv, asf, asx, etc., and relates to picture, document, audio, video, etc. User information includes, but is not limited to, user identification, user rating, user identification card, etc. information that may indicate user identity and/or rating or indicate user priority. The user identification includes, but is not limited to, a username. The fragment information includes fragment type, fragment number, fragment sequence number, and the like. The fragment type can represent information such as the importance degree of data in the fragment; the fragment sequence numbers are distributed in sequence, the fragment sequence numbers of the same file to be transmitted are not repeated, for example, the fragment sequence number of the first fragment to be transmitted of the file to be transmitted is 1, the fragment sequence number of the second fragment to be transmitted is 2, and so on, and merging needs to be performed according to the fragment sequence numbers during subsequent merging.

It should be noted that the second server provided in this embodiment is mainly used for storing the fragment summary information of all files that have been successfully transmitted by the terminal, for example, the MD5 value, where the MD5 value of the file to be transmitted or the fragment to be transmitted may be stored in the second server when it is detected that the file to be transmitted or the fragment to be transmitted is completely transmitted, so as to detect whether the file to be transmitted has been transmitted in real time during subsequent file transmission, and avoid transmitting the transmitted file again.

Optionally, after receiving the file fragment transmission request, the first server performs two main operations: triggering fragment uploading initialization operation and generating target fragment signature link operation. The fragment uploading initialization operation is used for telling the first server how many fragments to be transmitted need to be uploaded next, and generating a transmission event identifier uploadID of each file to be transmitted. And the transmission event identifications of the fragments to be transmitted of the same file to be transmitted are the same. And then the transmission event identifier uploadID of each file to be transmitted is sent to the second server, so that the transmission event identifier uploadID of each file to be transmitted is sent to the terminal through the second server.

Step 102, obtaining server information of a first server, and determining a target basic link corresponding to each file to be transmitted according to the server information, file information and user information of each file to be transmitted, and fragment information of a fragment to be transmitted corresponding to each file to be transmitted.

In this embodiment, the target basic link includes an IP, a port, a specific directory, and the like of the first server that stores the file to be transmitted. The first server is connected by IP and port, and the folder in the directory in the corresponding first server is opened by the specific directory. The server information, the file information, the fragment information and the user information can be input into the link determination model to be processed so as to output the target basic link corresponding to the file to be transmitted, or the target basic link corresponding to the file to be transmitted can be generated according to other modes according to the server information, the file information, the fragment information and the user information.

Specifically, the first server includes a link determining model, the link determining model includes a link feature extractor and a link decision maker, and the step of determining the target basic link corresponding to each file to be transmitted according to the server information, the file information and the user information of each file to be transmitted, and the fragment information of the fragment to be transmitted corresponding to each file to be transmitted specifically includes: inputting server information, file information of each file to be transmitted, user information and fragment information of the fragment to be transmitted corresponding to each file to be transmitted into a link characteristic extractor in a link determination model for processing to obtain link characteristic information; and inputting the link characteristic information into a link decision maker in the link determination model for processing so as to obtain a target basic link corresponding to each file to be transmitted.

It can be understood that the sizes of the files are different, the types of the fragments are different, the priorities of the users are different, the information of the servers is different, the IP addresses of the first servers for storing the files to be transmitted, which are determined in the link determination model, may be different, the specific storage paths may also be different, and these factors all affect the final determination of the target basic link.

Wherein the link determination model is pre-trained for direct use. The method for determining the model by training the link specifically comprises the following steps: inputting file information, fragment information and user information of transmission file samples in a file sample set into a link determination model to be trained, wherein the link determination model to be trained is a machine learning model such as a neural network model, each transmission file sample corresponds to a basic link label, and the basic link label comprises a first basic link or a plurality of basic links capable of storing the transmission file samples; processing by using a link characteristic extractor in a link determination model to be trained to obtain sample link characteristic information; inputting the sample link characteristic information into a link decision maker in a link determining model to be trained for processing so as to obtain a sample basic link corresponding to a transmission file sample; calculating the similarity between the sample basic link and the basic link label, and stopping training if the similarity is within a preset similarity range to obtain a link determination model; otherwise, continuing training, and continuously optimizing the model parameters of the link determination model to be trained according to the loss of the training process until convergence. It should be noted that the server information of the first server when the basic link label of the file sample is obtained is substantially the same as the server information when the link determination model to be trained is trained, for example, the sizes of the remaining storage spaces are not different or the same.

And 103, generating a target fragment signature link of the fragment to be transmitted corresponding to each file to be transmitted according to the transmission event identifier, the file information, the target basic link and the fragment information corresponding to each file to be transmitted.

The fragment information comprises the number of fragments and fragment serial numbers, the fragment serial numbers of the fragments to be transmitted in the same file to be transmitted are different, each fragment serial number corresponds to one fragment to be transmitted, each fragment serial number corresponds to one target fragment signature link, and the target fragment signature link is unique.

In this embodiment, the step of generating a target fragment signature link of a fragment to be transmitted corresponding to each file to be transmitted according to the transmission event identifier, the file information, the target basic link, and the fragment information corresponding to each file to be transmitted specifically includes: carrying out signature processing on file information of each file to be transmitted to obtain a file signature identifier of each file to be transmitted; and carrying out field splicing treatment on the target basic links, the file signature identifications, the transmission event identifications and the fragment serial numbers of the files to be transmitted to obtain target fragment signature links of the files to be transmitted, wherein the target fragment signature links are the same as the fragments of the files to be transmitted in number, and each target fragment signature link in each file to be transmitted corresponds to one fragment serial number of each file to be transmitted.

Specifically, the MD5 digest algorithm processing is performed on the file information or the file information is subjected to hash processing to obtain a file signature identifier, the file signature identifier is used for representing a specific file name, the file signature identifier is unique, then the field splicing processing is performed on the target base link, the file signature identifier, the transmission event identifier and one of the fragment serial numbers of each file to be transmitted to obtain a target fragment signature link corresponding to the fragment serial number, and each fragment serial number corresponds to one target fragment signature link to obtain the target fragment signature links with the same number as the fragments. If 6 fragment serial numbers are provided, 6 target fragment signature links are generated, and because the file signature identifier is unique, the 6 target fragment signature links are also unique.

For example, the target fragment signature link of the fragment to be transmitted corresponding to the fragment sequence number of 1 may be http://145.170.34.124:9000/23-45678/cd3abf8-ddde-1653-a05b-4ffd2a1 ebe 1-W.P.S9915.120.12.2019.exe

uploadID= 771234567891011

partnumber = 1. The target fragment signature link respectively represents an IP (Internet protocol) and a port of a first server, directory folder information for storing the fragment to be transmitted, a file signature identifier corresponding to a file name, a transmission event identifier and a fragment sequence number. Where uploadID and partnumber are the corresponding fields, "=" is followed by the value of the corresponding field. It should be noted that for the sake of explanation, some fields and values of the fields in the target fragment signature link are not encrypted, and in some other embodiments, these data may be encrypted to improve security.

Each target fragment signature link is only corresponding to the transmission of a fragment to be transmitted of a corresponding fragment serial number in a specific file to be transmitted, and cannot be used for other purposes, for example, the target fragment signature link cannot be used for the transmission of other fragments to be transmitted, so that the safety of data transmission is ensured.

Optionally, each target fragment signature link is configured with a time to live, when the target fragment signature link is generated or sent, a timer is started to time, if the time to live reaches the time to live, the target fragment signature link is set to be invalid, and after the time is invalid, the target fragment signature link becomes invalid and is not used any more. Different survival times can be set according to the file type of the file to be transmitted, for example, the survival time of the file type of the video class is 10 minutes, the survival time of the file type of the document class is 1 minute, and the like.

And 104, sending the target fragment signature links corresponding to the files to be transmitted to the terminal through the second server, and sequentially activating the target fragment signature links according to the user information and the transmission information of the files to be transmitted so that the terminal sequentially transmits the corresponding fragments to be transmitted to the first server through the sequentially activated target fragment signature links.

In this embodiment, the user information includes user level information, the transmission information includes transmission progress information, and the step of sequentially activating each target segment signature link according to the user information and the transmission information of each file to be transmitted specifically includes: if the user level information of the files to be transmitted is the same, determining the priority of the files to be transmitted according to the transmission progress information of the files to be transmitted; if the user grade information of the files to be transmitted is different, determining the priority of the files to be transmitted according to the user grade information of the files to be transmitted; and sequentially activating target fragment signature links corresponding to the files to be transmitted according to the priority of the files to be transmitted.

The transmission progress information represents the percentage of the number of the fragments to be transmitted, which are completely transmitted, in the file to be transmitted in the total number of the fragments to be transmitted in the file to be transmitted. And sequentially activating target fragment signature links corresponding to the next fragment to be transmitted after the last fragment to be transmitted is transmitted.

When the user grades of the files to be transmitted are the same, the file to be transmitted which is quickly uploaded can be preferentially transmitted by taking the transmission progress as the priority of the files to be transmitted, so that the file to be transmitted which is quickly completed is prevented from being transmitted again after a network fault or transmission interruption, the file transmission efficiency is improved, and the file transmission experience of a user is ensured; by taking the user grade information as the priority of the file to be transmitted corresponding to the user grade information, the data with high user grade can be transmitted preferentially, so that the transmission requirements of different user grades are met, various problems such as network faults, equipment faults and the like encountered by high-grade users in the subsequent file transmission process are reduced, and the file transmission safety of the high-grade users is ensured.

As an optional embodiment, the step of sequentially activating the target fragment signature link corresponding to each file to be transmitted according to the priority of each file to be transmitted specifically includes: determining the transmission quantity of the fragments to be transmitted simultaneously by the first server according to the server information of the first server; distributing corresponding transmission weight for each file to be transmitted according to the priority of each file to be transmitted; and distributing the activation denominations with the same transmission quantity to the files to be transmitted according to the transmission weight of the files to be transmitted, and sequentially activating target fragment signature links corresponding to the files to be transmitted containing the activation denominations.

For example, if there are 3 files to be transmitted: each file to be transmitted comprises 3 fragments to be transmitted and needs to be uploaded to a first server, and the first server can simultaneously transmit 6 fragments to be transmitted at the same time, namely the first server can simultaneously process the transmission of the 6 fragments to be transmitted. At this time, it is necessary to calculate the transmission weight of each file to be transmitted according to the priority of each file to be transmitted, for example, the transmission weight of file 1 is 10, the transmission weight of file 2 is 50, and the transmission weight of file 3 is 99. Thus, according to the transmission capability of the first server (the first server can simultaneously process the transmission of 6 fragments to be transmitted), the activation denominations are distributed for the file 1, the file 2 and the file 3 according to the transmission weight of each file to be transmitted, so that the file 1 obtains 1 activation denomination, the file 2 obtains 2 activation denominations, and the file 3 obtains 3 activation denominations. And finally, sequentially activating the target fragment signature links with the same number as the activation denominations in the files to be transmitted according to the activation denominations of the files to be transmitted, namely sequentially activating 1 target fragment signature link in the file 1, sequentially activating 2 target fragment signature links in the file 2 and sequentially activating 3 target fragment signature links in the file 3. Therefore, file transmission with different proportions can be carried out according to the priority of each file to be transmitted, and the transmission requirements of the files to be transmitted with different priorities are met.

The transmission weight to be transmitted corresponds to the priority of each file to be transmitted, and the priority of each file to be transmitted can be preset by a user or can be automatically generated according to the user information of each file to be transmitted. Specifically, the priority setting mode of the file to be transmitted may be set according to a specific application scenario, and is not specifically limited herein.

In this embodiment, in the process of uploading the target fragment of the target file, if the user cancels the uploading of the target file on the terminal or closes the browser that is currently uploading by the terminal, the transmission of the target file will be cancelled. In order to implement the breakpoint resume function, after the upload operation is cancelled, the target fragment of the target file that has been transmitted is stored in the first server, so that when the transmission operation on the target file is performed next time, only the target fragment that has not been transmitted needs to be subjected to file transmission, and the whole target file does not need to be transmitted again from the beginning.

However, when there are too many files in the first server to transmit only half of the files (the first server stores a plurality of incomplete files), a lot of server resources are occupied, and the files are difficult to clean after a long time. Therefore, referring to fig. 4 for solving the technical problem, fig. 4 is another schematic flow chart of the file transmission method according to the embodiment of the present invention, and as shown in fig. 4, the file transmission method according to the embodiment further includes steps 105 to 106.

And 105, acquiring the transmission progress information of each file to be transmitted in real time.

And acquiring the transmission progress information of each file to be transmitted in real time so as to monitor whether the transmission work of each file to be transmitted is normally operated.

And step 106, if the transmission progress information does not change within the preset time period, deleting the data related to the corresponding file to be transmitted in the first server.

When it is detected that the transmission progress information of a certain file to be transmitted is unchanged all the time, the duration time that the transmission progress information of the file to be transmitted is kept unchanged is judged, if the transmission progress information of the file to be transmitted is unchanged within a preset time period, if the transmission progress information of the file to be transmitted is 1 month long, the transmission process of the file to be transmitted is judged to be abnormal, the transmission-completed fragment to be transmitted of the file to be transmitted in the first server is directly deleted, and meanwhile, the second server is informed to delete the MD5 value of the corresponding fragment to be transmitted. Therefore, the available resources of the server can be effectively improved.

After the transmission of the fragments to be transmitted of the whole file to be transmitted is completed, all the fragments to be transmitted of the file to be transmitted need to be merged in a certain sequence, so that the whole file to be transmitted is stored in the first server. Specifically, please refer to fig. 4, the file transmission method provided in this embodiment further includes steps 107 to 109, and steps 107 to 109 in fig. 4 are a flow of the merging process of the fragments to be transmitted.

Step 107, receiving a file merging request.

The file merging request comprises a transmission event identifier of a file to be merged. The file merging request is generated after the terminal finishes transmitting all the fragments to be transmitted of the file to be transmitted, and the generated file merging request can be sent to the first server through the second server. Therefore, after the first server receives the file merging request, all the files to be transmitted in the file merging request are uploaded to the first server, the files to be transmitted can also be understood as the files to be merged, and the transmission event identifier of the files to be transmitted is also the transmission event identifier of the files to be merged.

And 108, determining the target fragment of the file to be merged transmitted by the corresponding target fragment signature link according to the transmission event identifier.

Taking the fragments to be transmitted with the same transmission event identification in the target fragment signature link as target fragments, wherein the transmission event identifications are the same, which means the same file to be transmitted; and merging the corresponding target fragments according to the fragment serial numbers in the target fragment signature link and the sequence of the fragment serial numbers to obtain a merged file. And merging according to the sequence of the fragment sequence numbers, so that the merged files can be merged according to a correct sequence, and the damage of the merged files is avoided.

And step 109, merging the corresponding target fragments according to the fragment serial numbers in the corresponding target fragment signature links to obtain a merged file.

The merged file is a file to be transmitted.

And the transmission of the whole file to be transmitted is finished.

To sum up, in the file transmission method provided in the embodiment of the present invention, file information, user information, transmission information of each to-be-transmitted file in a plurality of to-be-transmitted files corresponding to the fragment transmission request, and fragment information of a to-be-transmitted fragment corresponding to each to-be-transmitted file are obtained, then a target base link corresponding to each to-be-transmitted file is determined according to server information of the first server, file information, user information of each to-be-transmitted file, and fragment information of a to-be-transmitted fragment corresponding to each to-be-transmitted file, and a target fragment signature link of a to-be-transmitted fragment corresponding to each to-be-transmitted file is generated according to a transmission event identifier, file information, a target base link, and fragment information corresponding to each to-be-transmitted file, so that the terminal can directly transmit the corresponding to-be-transmitted fragment to the first server through the target fragment signature link, and the transfer is not required to be carried out through a second server, so that the file transmission efficiency in the cloud service is improved. In addition, by transmitting the fragments to be transmitted in the files to be transmitted instead of transmitting the whole files to be transmitted, the data which are transmitted again can be avoided, and the file transmission efficiency in the cloud service is further improved. In addition, according to the user information and the transmission information of each file to be transmitted, the signature links of each target fragment are sequentially activated, and the terminal can sequentially upload the designated fragments to be transmitted, so that the designated files to be transmitted are preferentially transmitted, the file transmission efficiency of the designated files is improved, and the user experience is improved.
