Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
As background art, with the rapid development of mobile internet and the continuous popularization of electronic devices, users have more demands on mobile internet, and file transmission, which is a practical function of electronic devices, well meets the user demands and is becoming more and more popular.
Nowadays, files of size above 100M and even GB are becoming more and more large, such as design manuscripts, software development kits, video materials, etc., and the need for users to send large files is becoming more and more common due to business needs.
At present, when a user sends a relatively large file, the related art mainly includes two schemes:
according to the manual segmentation scheme, when a user sends a large file, the user is generally required to manually segment the large file into a plurality of small files and then send the small files one by one, so that the file transmission efficiency is low, the files related to privacy safety are easily transmitted to the other side, high-efficiency safe transmission of the files cannot be achieved, and the use experience of the user is influenced.
In the relay transmission scheme, when a user sends a relatively large file, the file is usually sent or uploaded to a relay application program directly, and then the relay application program sends the file to a target object. As shown in fig. 1, when the file sender M1 wants to send a file a (250M), a file B (300M), and a file C (250M) to the file receiver M2, it needs to upload three files to the relay application N by "relay sending", and then N is used as a file relay, and the file receiver M2 downloads the file a, the file B, and the file C from the relay application N by "relay downloading", so as to complete the transmission of the three files. However, because the transit application usually has a problem of security risk or usage limitation, it often results in that a large file is difficult to successfully transmit, so that efficient and secure transmission of the file cannot be achieved, and the user experience is affected.
In view of the problems in the related art, an embodiment of the present application provides a file transmission method, where when a target file is obtained, an electronic device can automatically split the target file when a storage space occupied by the target file is greater than a preset threshold, that is, the target file is a large file, so as to obtain at least two subfiles whose occupied storage space is less than or equal to the preset threshold, and thus, the large file can be successfully split into at least two small files. On the basis, the content characteristics of all the subfiles are extracted, the target subfiles with the content characteristics meeting preset safety conditions, namely the subfiles meeting the requirements of user privacy safety, are determined from all the subfiles, and the target subfiles are transmitted to a receiver of the files. Therefore, the user can split and send the large file while meeting the requirement of user privacy safety without manual splitting, so that high-efficiency safe transmission of the file is realized, and the problem that high-efficiency safe transmission of the file cannot be realized in the related technology is solved.
The following describes the file transmission method provided by the embodiment of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 2 is a schematic flowchart of a file transfer method provided in an embodiment of the present application, where an execution main body of the file transfer method may be an electronic device, and as shown in fig. 2, the file transfer method provided in the embodiment of the present application may include:
s201, acquiring a target file.
In one embodiment, the target file may comprise various types of files, such as text, multimedia, and so on.
Such as images, sound, data compression files, software development kits, video material, etc.
In one embodiment, obtaining the target file may include: firstly, receiving file sending input of a user; then, in response to a file transmission input, a target file is acquired.
For example, if the user wants to send file a to the file recipient M2, the user may click "file send" as shown in fig. 3. In this way, the electronic device can receive a file transmission input from the user, and in response to the input, acquire the file a, i.e., the target file.
S202, under the condition that the storage space occupied by the target file is larger than a first preset threshold value, the target file is split, and at least two first subfiles are obtained.
And the storage space occupied by the first subfile is not greater than a first preset threshold value.
In one embodiment, the first preset threshold may be a maximum storage space occupied by a transmission file allowed by an application program transmitting the target file.
For example, when a file sender wants to transmit a target file through an APP1 on an electronic device, and the maximum storage space occupied by the transmission file allowed by the APP1 is 100M, 100M may be used as a first preset threshold.
Specifically, the electronic device determines whether the storage space occupied by the target file is greater than a first preset threshold, and splits the target file to obtain at least two first subfiles when the storage space occupied by the target file is greater than the first preset threshold, that is, the size of the target file exceeds the maximum value of the storage space occupied by the transmission file allowed by the application program for transmitting the target file.
It should be noted that the first preset threshold may also be set according to specific requirements, and the first preset threshold may be the same as or smaller than a maximum value of a storage space occupied by a transmission file allowed by an application program that transmits a target file.
In an embodiment, splitting the target file to obtain at least two first subfiles when the storage space occupied by the target file is greater than a first preset threshold may include: and splitting the target file according to a first preset threshold value to obtain N first subfiles, wherein N is a numerical value obtained by rounding up the quotient of the storage space occupied by the target file and the first preset threshold value, and N is an integer not less than 2.
For example, the first preset threshold is 100M, the file a is a target file, and the storage space occupied by the file a is 250M. After the electronic device acquires the file a, it is first determined that the storage space occupied by the file a is greater than 100M, then the file a is split according to 100M, and the file a is split into N sub-files, where N is a numerical value obtained by rounding up a quotient of the storage space 250M occupied by the file a and a first preset threshold 100M, that is, 3. As shown in fig. 4, the electronic device splits a file a occupying a storage space of 250M into three subfiles a1, a2 and A3, the three subfiles occupying storage spaces of 100M, 100M and 50M, respectively.
In an embodiment, the splitting the target file to obtain at least two first subfiles may include: extracting semantic features corresponding to the file fragments; splitting the target file according to a mode of attributing file fragments with the same semantic features to one subfile to obtain at least two first subfiles, wherein each first subfile corresponds to one semantic feature.
For example, the first preset threshold is 100M, the file a is a target file, the file a includes four file fragments P1, P2, P3 and P4, and the storage space occupied by the file a is 250M. After the electronic device acquires the file A, firstly determining that the occupied storage space of the file A is larger than 100M, then extracting the semantic features of each file segment to obtain semantic features Y1 and Y2 corresponding to P1, Y3 corresponding to P3 and Y1 corresponding to P4, wherein the semantic features Y1 and P2 correspond to the semantic features. Finally, the file A is divided into three subfiles A1, A2 and A3 according to the mode of attributing the file segments with the same semantic features to one subfile, wherein A1 comprises file segments P1 and P4, A2 comprises file segment P2, and A3 comprises file segment P3.
Therefore, the electronic equipment can split the target file into the plurality of small files under the condition that the storage space occupied by the target file is determined to be large, namely the target file is the large file, so that the electronic equipment can send the small files successfully subsequently, the user does not need to split the small files manually, the operation steps of the user when sending the files are reduced, the automatic splitting of the large files is realized, and the use experience of the user is improved.
S203, extracting the content characteristics of at least two first subfiles.
Specifically, after the splitting of the target file is completed, the electronic device extracts content features of each first subfile, wherein each first subfile corresponds to at least one content feature.
In an embodiment, the content feature may be information obtained by summarizing the file content of the first subfile, may also be a keyword corresponding to the file content of the first subfile, and may also be a category to which the file content of the first subfile belongs.
In one embodiment, when the electronic device extracts the content features of the first subfile, the parallel extraction mode may be selected according to a current memory operation condition of the electronic device.
In one embodiment, extracting the content features of the at least two first subfiles may include: and under the condition that the residual operation memory capacity of the electronic equipment is larger than a second preset threshold value, extracting the content characteristics of at least two first subfiles in parallel.
For example, the second preset threshold is 3M, the electronic device splits the file a occupying the storage space of 250M into three subfiles a1, a2 and A3, where the three subfiles occupy storage spaces of 100M, 100M and 50M, respectively. If the remaining operating memory capacity of the electronic device is 4M, the content features of the three subfiles a1, a2 and A3 can be extracted in parallel.
Therefore, the electronic equipment can improve the extraction efficiency of the content features, and the transmission efficiency of the target file is improved.
S204, determining a target first subfile with content characteristics meeting preset safety conditions from the at least two first subfiles.
Specifically, each first subfile corresponds to at least one content characteristic, and the electronic device determines whether each subfile meets the privacy security requirement by checking whether the content characteristic corresponding to each subfile meets a preset security condition.
It should be noted that the preset security condition is related to privacy security, and may be set according to specific requirements.
For example, if the preset security condition is that the client list of the enterprise is not included, the electronic device may check whether the content characteristics corresponding to each subfile are related to the client name of the enterprise, and filter out a first subfile whose content characteristics are related to the client name of the enterprise, to obtain a first subfile that satisfies the preset condition, i.e., a target subfile.
In an embodiment, when the electronic device checks whether the content feature corresponding to each first subfile meets a preset security condition, the electronic device may determine the number of parallel checking tasks that may be currently allowed according to a current memory operation condition of the electronic device.
For example, the electronic device splits a file a occupying a storage space of 250M in three subfiles a1, a2 and A3, the three subfiles occupying storage spaces of 100M, 100M and 50M, respectively. If the remaining operating memory capacity of the electronic device is 3M at this time, and the number of parallel check tasks that can be currently allowed is 2, the electronic device may check whether the content features of a1 and a2 meet the preset safety conditions in parallel, and then check A3; if the remaining operating memory capacity of the electronic device is 1M at this time, and the number of parallel checking tasks that can be currently allowed is 1, the electronic device serially checks whether the content features of a1, a2, and A3 satisfy the preset safety condition in sequence.
In one embodiment, after determining a target first subfile with content characteristics satisfying a preset security condition from among the at least two first subfiles, the method may further include: a target interface is displayed that includes a target first subfile.
For example, after determining that the first subfiles a1, a2 and A3 all satisfy the preset security condition, the electronic device determines that a1, a2 and A3 all are target first subfiles, and displays a target interface including "privacy compliance" of the files a1, a2 and A3 as shown in fig. 5.
For another example, after determining that the first subfiles a1 and a2 satisfy the preset security condition and that A3 does not satisfy the preset security condition, the electronic device determines that a1 and a2 are the target first subfile, and displays a target interface including files a1 and a2 of "privacy compliance" and files A3 of "privacy non-compliance" as shown in fig. 6.
Therefore, the electronic equipment can determine the number of parallel checking tasks which can be allowed currently according to the current memory running condition of the electronic equipment, and whether the content features corresponding to the subfiles meet the preset safety conditions or not is checked in parallel under the condition that the remaining running memory capacity of the electronic equipment is sufficient, so that the checking efficiency of the content features is improved, and the transmission efficiency of the target file is improved.
S205, transmitting the target first subfile to the receiving party.
In one embodiment, in the presence of at least two target first subfiles, the electronic device transmits the target first subfiles in sequence.
For example, the target first subfile is a1, a2, A3, and the electronic device sequentially transmits a1, a2, A3.
In one embodiment, when the electronic device transmits the target first subfile, the parallel transmission mode may be selected according to a current memory operation condition or a network rate of the electronic device.
In one embodiment, in the case where there are at least two target first subfiles, transmitting the target first subfile may include: and under the condition that the remaining operation memory capacity of the electronic equipment is larger than a second preset threshold value or the network speed is larger than a preset speed threshold value, transmitting at least two target first subfiles in parallel.
For example, the preset rate threshold is 3Mbps, and the target first subfiles are a1, a2, A3. If the network rate of the electronic device is 4Mbps, the three subfiles a1, a2 and A3 may be transmitted in parallel.
In another embodiment, when the electronic device transmits the target first subfile, the electronic device may determine the number of parallel transmission tasks that may be currently allowed according to the current memory operation condition or the network rate of the electronic device.
For example, the number of parallel transmission tasks corresponding to the network rate in the interval of 3Mbps-6Mbps is 2, and the target first subfiles are A1, A2 and A3. If the network rate of the electronic device is 4Mbps, a1 and a2 may be transmitted in parallel, and A3 may be transmitted finally.
According to the file transmission method provided by the embodiment of the application, when the target file is obtained, the electronic device can automatically split the target file under the condition that the storage space occupied by the target file is larger than the preset threshold value, namely the target file is a large file, so that at least two sub-files occupying the storage space smaller than or equal to the preset threshold value are obtained, and thus the large file can be successfully split into at least two small files. On the basis, the content characteristics of all the subfiles are extracted, the target subfiles with the content characteristics meeting preset safety conditions, namely the subfiles meeting the requirements of user privacy safety, are determined from all the subfiles, and the target subfiles are transmitted to a receiver of the files. Therefore, the user can split and send the large file while meeting the requirement of user privacy safety without manual splitting, so that high-efficiency safe transmission of the file is realized, and the problem that high-efficiency safe transmission of the file cannot be realized in the related technology is solved.
As a specific embodiment, fig. 7 is a schematic flowchart of another file transmission method provided in the embodiment of the present application, where an execution main body of the file transmission method may be an electronic device, as shown in fig. 7, the file transmission method provided in the embodiment of the present application may include:
s701, acquiring a target file.
S702, determining whether the storage space occupied by the target file is larger than the maximum value of the storage space occupied by the transmission file allowed by the application program for transmitting the target file, and if not, executing S703-S706; if so, S707-S710 are executed.
S703, extracting the content characteristics of the target file.
S704, determining whether the content characteristics of the target file meet preset safety conditions, if so, executing S705, and if not, executing S706.
S705, transmitting the target file to the receiving party.
S706, canceling the transmission.
S707, splitting the target file to obtain a plurality of subfiles.

S709, determine a target subfile whose content characteristics satisfy a preset security condition from the plurality of subfiles.
And S710, transmitting the target subfiles to the receiver in parallel.
Therefore, the electronic equipment can select a corresponding file processing mode according to the size of the storage space occupied by the target file, and automatically split the target file to obtain a plurality of smaller subfiles under the condition that the storage space occupied by the target file is larger than the maximum value of the storage space occupied by the transmission file allowed by the application program for transmitting the target file, so that the smooth transmission of the target file is ensured.
In some embodiments of the present application, in order to obtain a large file according to a plurality of small files sent by an electronic device, fig. 8 is a flowchart illustrating another file transmission method provided in an embodiment of the present application, where an execution subject of the file transmission method may be the electronic device, as shown in fig. 8, the file transmission method provided in an embodiment of the present application may include:
s801, receiving a plurality of second subfiles.
Wherein the plurality of second subfiles are derived from the same file.
S802, combining the plurality of second subfiles to obtain a second file.
In an embodiment, each second subfile corresponds to identification information, where the identification information is used to identify an appearance order of the second subfile in the second file, and combining the plurality of second subfiles to obtain the second file may include: and sequentially combining the plurality of second subfiles according to the appearance sequence of each second subfile in the second file.
For example, the files B1, B2, B3 and B4 are four second subfiles received by the electronic device, the corresponding identification information is n1, n3, n2 and n4 respectively, and the appearance sequence of B1, B2, B3 and B4 in the second file is first, third, second and fourth respectively. Therefore, the electronic device merges the files B1, B3, B2, and B4 in order of appearance of the four second subfiles, and finally obtains the second file B.

In the related technology, when a user posts comments through some websites, application programs and other channels, the number of words of the comments is usually limited, so that the user can only post the comments for multiple times or reduce the number of words of the comments manually, and thus, the use experience of the user is poor.
In some embodiments of the present application, in order to improve the experience of a user, an embodiment of the present application further provides a comment sending method, where an execution subject of the comment sending method may be an electronic device, and the method may include: firstly, obtaining a target comment; then, under the condition that the number of words of the target comment is larger than a second preset threshold value, splitting the target comment to obtain at least two sub comments, wherein the number of words of each sub comment is not larger than the second preset threshold value; and finally, sequentially sending at least two sub-comments.
It should be noted that the second preset threshold may be a maximum number of comment words allowed by a website or an application that sends a comment, or may be set according to a specific requirement.
In one embodiment, the target comment includes a plurality of comment segments, and splitting the target comment to obtain at least two sub comments when the number of words of the target comment is greater than a second preset threshold value may include: extracting semantic features corresponding to the comment fragments; and splitting the target comment to obtain at least two sub-comments according to a mode of attributing the comment fragments with the same semantic features to one sub-comment.
As a specific example, the first preset threshold is 100, the number of the target comment words is 103, and the target comment includes four comment fragments p1, p2, p3 and p 4. After the electronic equipment acquires the target comment, firstly, the number of words of the target comment is determined to be more than 100, then, the semantic features of each comment fragment are extracted, and the semantic features y1 corresponding to p1, y2 corresponding to p2, y3 corresponding to p3 and y1 corresponding to p4 are obtained. Finally, the target comment is divided into three sub-comments a1, a2 and a3 in a manner that the comment segments with the same semantic features are attributed to one sub-comment, wherein the number of words of the three sub-comments is less than 100, the a1 comprises comment segments p1 and p4, the a2 comprises a comment segment p2, and the a3 comprises a comment segment p 3.
In this way, when the target comment is acquired, the electronic device can automatically split the target comment under the condition that the word number of the target comment is greater than the preset threshold value, so that at least two sub comments with the word number less than or equal to the preset threshold value are obtained. On the basis, the electronic equipment can send the sub-comments in sequence. Therefore, even if the comment word number of the user exceeds the range, the user does not need to manually send comments for multiple times or reduce the comment word number, and the experience of the user is effectively improved.
In the related art, before sending a photo, a user generally needs to process a part of the photo related to user privacy, for example, the user mosaics a part of an image related to own privacy and then sends the processed picture to another party.

It should be noted that the preset privacy security condition may be set according to specific requirements, for example, the preset privacy security condition may be that the image does not include the identity information of the user, an indoor scene, and the like.
As a specific embodiment, the preset privacy security condition is that the image does not contain the identity information of the user, and after the electronic device acquires the target image X, the electronic device performs image segmentation on the target image X to obtain sub-images X1, X2, and X3; then, the electronic equipment respectively carries out image recognition on the three sub-images to obtain the recognition feature 'person' of X1, the recognition feature 'ticket' of X2 and the recognition feature 'scenery' of X3; the electronic equipment determines that the identification feature 'ticket' of the sub-image X2 contains the identity information of the user and does not meet the preset privacy security conditions, so that the X2 is subjected to fuzzy processing to obtain a fuzzy image, the fuzzy image is combined with the X1 and the X3, and the combined image is sent to a receiver.
In this way, when the target image is acquired, the electronic device can automatically process the target image and fuzzify the image part which does not meet the user privacy security. Therefore, the user can successfully send the image meeting the privacy safety of the user without manually carrying out image processing operation, the step of sending the photo by the user is simplified, and the user experience is effectively improved.
