The operation is simple, the transmission is based on the wireless local area network, the transmission speed is fast, and the efficiency of data transfer is improved.

[0019] like Figure 1 As shown, an embodiment of the present invention provides a data transfer method, which is applied to a first terminal and may specifically include the following steps: S102: A first terminal enters a group using a preset group key. The group includes a plurality of terminals and the plurality of terminals are all located in the same wireless local area network.

[0020] The group key may be determined by pre-negotiation by multiple terminals in the group, and after the group key is determined, any terminal in the group may enter the group by inputting the group key. The wireless local area network may be Wi-Fi, etc. The first terminal may be any terminal in the group, without specific limitation.

[0021] S104: Display a target icon, where the target icon is used to indicate other terminals in the group except the first terminal or a public space, where the public space is used for the terminals in the group to share data.

[0022] The first terminal may display a target icon on the interface, and the target icon may be one or more. For example, the target icon may include icons of one or more other terminals in the group, or icons of a public space, or icons of one or more other terminals in the group and icons of a public space, which is not specifically limited in this embodiment.

[0023] In the embodiment of the present invention, the public space refers to the storage space used by each terminal in the group to realize data transfer, including cache or hard disk, which is not specifically limited.

[0024] S106: Acquire the data to be sent, save the data to be sent as a temporary file, and display an icon of the temporary file.

[0025] The data to be sent may be a file stored in the first terminal, such as a word file, a pdf file, or a jpg file; or, the data to be sent may be content in an application of the first terminal, such as text, a picture, or an emoticon package, etc., without specific limitation.

[0026] S108: receiving a first operation, and in response to the first operation, dragging the icon of the temporary file to the target icon to send the temporary file to other terminals or a public space in the group indicated by the target icon except the first terminal.

[0027] In the embodiment of the present invention, the first operation may be a pre-specified operation, such as a long press or a drag operation, etc., which is not specifically limited.

[0028] When the target icon indicates other terminals in the group, the temporary file can be sent to the other terminals. When the target icon indicates a public space, the temporary file can be sent to the public space.

[0029] In one implementation manner, the target icon is an icon of the second terminal, and the above step S108 may include: A first operation is received, and in response to the first operation, an icon of the temporary file is dragged to an icon of the second terminal to send the temporary file to the second terminal.

[0030] Accordingly, after sending the temporary file to the second terminal, the method may further include: The first terminal receives the notification sent by the second terminal after receiving the temporary file, and deletes the temporary file locally.

[0031] In another implementation manner, the target icon is an icon of a public space, and the above step S108 may include: receiving a first operation, and in response to the first operation, dragging an icon of the temporary file to an icon of the public space to split the temporary file into a plurality of file fragments; Based on the cache space size of each terminal in the group, multiple file fragments are sent to each terminal respectively; The above-mentioned multiple file fragments are used for data recovery when any terminal in the group downloads a file from the public space.

[0032] In the embodiment of the present application, the sending of the plurality of file fragments to each terminal based on the cache space size of each terminal in the group may include: The multiple file fragments are sent to each terminal respectively according to the size of the multiple file fragments and the cache space size of each terminal in the group.

[0033] In one implementation, multiple file fragments may be sent to each terminal separately according to the principle that file fragments with large capacity are distributed to terminals with large cache space.

[0034] In the embodiment of the present application, after sending the plurality of file fragments to each terminal respectively, the following may also be included: The first terminal receives the notification sent by each terminal after receiving the file fragment, and deletes the temporary file locally.

[0035] In the embodiment of the present application, the above method may further include: When any terminal in the group exits the group, any terminal generates a file key based on the stored file fragments, uploads the file fragments and the file key to the cloud, and synchronizes the file key to other terminals in the group.

[0036] The above method provided by the embodiment of the present invention is that the first terminal enters the group through a preset group key, the group includes multiple terminals and the multiple terminals are all located in the same wireless local area network, a target icon is displayed, the target icon is used to indicate other terminals or public spaces in the group except the first terminal, the public space is used for the terminals in the group to share data, obtain data to be sent, save the data to be sent as a temporary file, display the icon of the temporary file, receive a first operation, and in response to the first operation, drag the icon of the temporary file to the target icon to send the temporary file to other terminals or public spaces in the group indicated by the target icon except the first terminal, thereby realizing data transfer between multiple terminals, which can be completed without relying on a third-party platform, is simple to operate, and is transmitted based on the wireless local area network, with a fast transmission speed, thereby improving the efficiency of data transfer.

[0037] like Figure 2 As shown, an embodiment of the present invention provides another data transfer method, which is applied to a first terminal and may specifically include the following steps: S202: A first terminal enters a group using a preset group key. The group includes a plurality of terminals and the plurality of terminals are all located in the same wireless local area network.

[0038] This method of transferring data based on the same wireless local area network can save the process of establishing a connection. Data transfer between terminals in a group can be achieved based on the Wi-Fi connection and the input of the group key. It is simple to operate, highly efficient, and can save terminal traffic.

[0039] S204: Displaying the icon of the second terminal.

[0040] S206: Acquire the data to be sent, save the data to be sent as a temporary file, and display an icon of the temporary file.

[0041] The data to be sent may be obtained by the first terminal from local storage, such as obtaining a file from a file manager, or obtaining a picture from an album, or may be text, pictures or emoticons dragged from an application, etc., without specific limitation.

[0042] S208: receiving a first operation, and in response to the first operation, dragging the icon of the temporary file to the icon of the second terminal to send the temporary file to the second terminal.

[0043] The second terminal may be any terminal in the group except the first terminal, and is not specifically limited.

[0044] This method of triggering data transfer by dragging icons does not require tedious operation steps such as right-clicking and selecting the required options, which greatly simplifies the operation process, improves transmission efficiency, and is highly practical.

[0045] S210: Receive a notification sent by the second terminal after receiving the temporary file, and delete the temporary file locally.

[0046] This method of deleting temporary files after data transmission is completed can reduce the local space resources occupied by temporary files.

[0047] Figure 3 This is a schematic diagram of an interface for sending data to other terminals in a group provided by an embodiment of the present invention. Figure 3 , the lower left corner of the interface of the first terminal (corresponding to user 1) displays temporary files, and the right side displays icons of other terminals in the group, such as the icon of user 2, the icon of user 3, etc., as well as the icon of the public space. When the user long presses the temporary file and moves to the icon of user 2, drags the icon of the temporary file to the icon of user 2, triggering the sending of the temporary file to the terminal of user 2, completing the data transfer between different terminals in the group, the operation is simple and convenient, and the transmission efficiency is high.

[0048] The above method provided by the embodiment of the present invention is that the first terminal enters the group through a preset group key, the group includes multiple terminals and the multiple terminals are all located in the same wireless local area network, the icon of the second terminal is displayed, the data to be sent is obtained, the data to be sent is saved as a temporary file, the icon of the temporary file is displayed, the first operation is received, and in response to the first operation, the icon of the temporary file is dragged to the icon of the second terminal to send the temporary file to the second terminal, thereby realizing data transfer between different terminals in the group, which can be completed without relying on a third-party platform, is simple to operate, and is transmitted based on the wireless local area network, with a fast transmission speed, thereby improving the efficiency of data transfer.

[0049] like Figure 4 As shown, an embodiment of the present invention provides another data transfer method, which is applied to a first terminal and may specifically include the following steps: S402: A first terminal enters a group using a preset group key. The group includes multiple terminals and the multiple terminals are all located in the same wireless local area network.

[0050] S404: Display an icon of a public space, where the public space is used for terminals in the group to share data.

[0051] For example, five terminals are located in the same Wi-Fi network and enter the group through the pre-negotiated group key. Each terminal in the group can divide the public space in its own storage for data transfer cache and shared data. Any terminal in the group can upload the data it wants to share to the public space to share it with other terminals in the group.

[0052] S406: Acquire the data to be sent, save the data to be sent as a temporary file, and display an icon of the temporary file.

[0053] S408: receiving a first operation, and in response to the first operation, dragging the icon of the temporary file to the icon of the public space to divide the temporary file into a plurality of file fragments.

[0054] The number of file fragments divided into temporary files can be set as needed, such as the number of file fragments is equal to the total number of terminals in the group, that is, each terminal including the first terminal stores a file fragment.

[0055] Alternatively, a threshold of the cache space may be set, and when the cache space of the terminal is lower than the threshold, the file fragments are not saved. Therefore, after filtering out the terminals whose cache space is lower than the threshold, the number of remaining terminals is determined as the number of file fragments, and accordingly, the segmented file fragments are sent to the remaining terminals.

[0056] S410: Based on the buffer space size of each terminal in the group, send multiple fragments to each terminal respectively.

[0057] The above-mentioned multiple file fragments are used for data recovery when any terminal in the group downloads the file from the public space. That is, any terminal can integrate all the file fragments after downloading them, so as to restore the file.

[0058] This method of dividing the file into file fragments and saving them to multiple terminals can avoid the waste of resources caused by saving the file in one terminal. Multi-point saving can greatly save storage resources.

[0059] In one implementation, the above step S410 may include: The multiple file fragments are sent to each terminal respectively according to the size of the multiple file fragments and the cache space size of each terminal in the group.

[0060] In one implementation, multiple file fragments may be sent to each terminal separately according to the principle that fragments with large capacity are allocated to terminals with large cache space.

[0061] For example, a temporary file is divided into five file fragments, which are file fragments 1 to 5 in order of capacity, and the five terminals in the group are terminals 1 to 5 in order of cache space. Then, file fragments 1 to 5 can be sent to terminals 1 to 5 in sequence.

[0062] S412: Receive notifications sent by each terminal after receiving the file fragments, and delete the temporary files locally.

[0063] This method of deleting temporary files after the file fragment transfer is completed can reduce the local space resources occupied by temporary files.

[0064] In the embodiment of the present invention, the above method may further include: When any terminal in the group exits the group, any terminal generates a file key based on the stored file fragments, uploads the file fragments and the file key to the cloud, and synchronizes the file key to other terminals in the group.

[0065] The grouped terminals can exit the group at any time, such as leaving the Wi-Fi range. Since the terminal exiting the group saves file fragments, it is necessary to upload the file fragments to the cloud to ensure that other terminals can obtain complete file fragments when downloading shared files.

[0066] In addition, in order to ensure the security of data transfer, the terminal exiting the group can also generate a file key for the file fragment and upload the file key to the cloud, so that the cloud can verify the legitimacy of the terminal requesting the file fragment based on the file key. In addition, the terminal exiting the group also synchronously sends the file key to other terminals in the group, which can facilitate other terminals to download the corresponding file fragment from the cloud based on the file key. This method avoids the loss of file fragments, ensures the reliability of data transfer, and improves the security of transmission through file keys.

[0067] Figure 5 A schematic diagram of an interface for sharing data in a public space provided by an embodiment of the present invention. Figure 5 , the temporary file is displayed in the lower left corner of the interface of the first terminal, and the icon of the public space is displayed on the right side. When the user long presses the temporary file and moves to the icon of the public space, drags the icon of the temporary file to the icon of the public space, triggering the temporary file to be split into multiple file fragments and sent to each terminal in the group. Other terminals can download files from the public space to achieve data sharing within the group. The operation is simple and convenient, and the transmission efficiency is high.

[0068] The above method provided by the embodiment of the present invention is that the first terminal enters the group through a preset group key, the group includes multiple terminals and the multiple terminals are all located in the same wireless local area network, the icon of the public space is displayed, the public space is used for the terminals in the group to share data, obtain data to be sent, save the data to be sent as a temporary file, display the icon of the temporary file, receive a first operation, and in response to the first operation, drag the icon of the temporary file to the icon of the public space to divide the temporary file into multiple file fragments, based on the cache space size of each terminal in the group, send the multiple fragments to each terminal respectively, receive the notification sent by each terminal after receiving the file fragments, delete the temporary file locally, and realize the sharing of data in the group. Other terminals can download the shared files without relying on a third-party platform. The operation is simple, the transmission is based on the wireless local area network, the transmission speed is fast, and the efficiency of data transfer is improved.

[0069] like Figure 6 As shown, an embodiment of the present invention provides another data transfer method, which is applied to a second terminal and may specifically include the following steps: S602: The second terminal enters a group using a preset group key. The group includes multiple terminals and the multiple terminals are all located in the same wireless local area network.

[0070] S604: Display a target icon, where the target icon is used to indicate other terminals in the group except the second terminal or a public space, where the public space is used for the terminals in the group to share data.

[0071] S606: When the first terminal in the group triggers temporary file transmission based on the first operation, receive the temporary file sent by the first terminal.

[0072] The first operation may be a pre-specified operation, including but not limited to: a long press or a drag operation, etc.

[0073] In the embodiment of the present invention, the above method may further include: When a terminal in the group uploads a temporary file to the public space, the receiving terminal divides the temporary file into file fragments sent based on the cache space size of the second terminal.

[0074] In the embodiment of the present invention, the above method may further include: Based on the displayed icon of the public space, select a file to be downloaded from the public space; receiving file fragments of the file sent by other terminals in the group; When it is determined that the received file fragments are complete, the locally stored file fragments and the received file fragments are integrated to restore the file; When it is determined that the received file fragments are incomplete, the target file fragments are downloaded from the cloud based on the file key, and then integrated with the locally stored file fragments and the received file fragments to restore the file.

[0075] The above file key is sent by the terminal that has exited the group and uploaded the target file fragment to the cloud.

[0076] In the above method provided by the embodiment of the present invention, the second terminal enters the group through a preset group key, the group includes multiple terminals and the multiple terminals are all located in the same wireless local area network, a target icon is displayed, the target icon is used to indicate other terminals or public spaces in the group except the second terminal, the public space is used for the terminals in the group to share data, and when the first terminal in the group triggers a temporary file transmission based on a first operation, a temporary file sent by the first terminal is received, thereby realizing data transfer between different terminals in the group, which can be completed without relying on a third-party platform, is simple to operate, and is transmitted based on the wireless local area network, with a fast transmission speed, thereby improving the efficiency of data transfer.

[0077] like Figure 7 As shown, an embodiment of the present invention provides another data transfer method, which is applied to a second terminal and may specifically include the following steps: S702: The second terminal enters a group using a preset group key. The group includes multiple terminals and the multiple terminals are all located in the same wireless local area network.

[0078] S704: Display an icon of a public space, where the public space is used for terminals in the group to share data.

[0079] S706: When a terminal in the group uploads a temporary file to the public space, receiving file fragments sent by the terminal after splitting the temporary file based on the cache space size of the second terminal.

[0080] In an embodiment of the present invention, after the terminal that uploads a temporary file to the public space performs file segmentation, in addition to sending the file fragments to the second terminal, other file fragments are also sent to one or more terminals other than the second terminal in the group. The storage space occupied by each file fragment in the corresponding terminal after the file segmentation together constitutes the above-mentioned public space. By segmenting the file and distributing the file fragments to multiple terminals for storage, the waste of resources in the public space can be reduced.

[0081] S708: Based on the displayed icon of the public space, select a file to be downloaded from the public space, and receive file fragments of the file sent by other terminals in the group.

[0082] The public space may contain one or more files, such as files uploaded by different terminals to the public space. The public space may also store snapshots of shared files uploaded by various terminals, which is not specifically limited.

[0083] S710: Integrate and restore files based on the locally stored file fragments and the received file fragments.

[0084] In the embodiment of the present invention, the above step S710 may include: When it is determined that the received file fragments are complete, the locally stored file fragments and the received file fragments are integrated to restore the file; in this scenario, no terminal exits the grouping, and the file fragments are stored on each terminal and are not uploaded to the cloud.

[0085] When it is determined that the received file fragments are incomplete, the target file fragments are downloaded from the cloud based on the file key, and then integrated with the locally stored file fragments and the received file fragments to restore the file, wherein the file key is sent by the terminal that has exited the group and uploaded the target file fragments to the cloud. In this scenario, a terminal exits the group and uploads its own stored file fragments to the cloud. Therefore, after the second terminal determines that the received file fragments are incomplete, it needs to download the missing file fragments, namely the target file fragments, from the cloud, so that the complete fragments can be obtained, which can prevent the loss of data after disconnection.

[0086] In the embodiment of the present invention, the above method may further include: When the target file fragments are downloaded from the cloud and the file is restored successfully, based on the cache space size of each terminal in the group, the target file fragments downloaded from the cloud are divided into multiple new file fragments and sent to each terminal.

[0087] In this case, the cloud no longer needs to save the target file fragments previously uploaded by a terminal. Instead, the terminal that downloaded the target file fragments will re-divide the target file fragments and save them to each terminal. This not only saves storage space in the cloud, but also eliminates the need to go through the cloud to obtain the complete fragments later. It can be completed within the wireless LAN, which improves transmission efficiency and saves terminal traffic.

[0088] In the above method provided by the embodiment of the present invention, the second terminal enters the group through a preset group key, the group includes multiple terminals and the multiple terminals are all located in the same wireless local area network, a target icon of the public space is displayed, the public space is used for the terminals in the group to share data, and when a terminal in the group uploads a temporary file to the public space, the terminal receives the file fragments sent by the second terminal after splitting the temporary file based on the cache space size of the second terminal, selects the file to be downloaded from the public space based on the icon of the public space displayed, receives the file fragments of the file sent by other terminals in the group, and restores the file based on the locally stored file fragments and the received fragments, thereby realizing the transfer of shared files in the group, which can be completed without relying on a third-party platform, is simple to operate, is transmitted based on the wireless local area network, has a fast transmission speed, and improves the efficiency of data transfer.

[0089] The above is a data transfer method provided by an embodiment of the present invention. Based on the same idea, an embodiment of the present invention also provides a data transfer device 800, which is applied to a first terminal, such as Figure 8 As shown, the data transfer device includes: A connection module 801, configured to enter a group using a preset group key, wherein the group includes a plurality of terminals and the plurality of terminals are all located in the same wireless local area network; A display module 802, used to display a target icon, where the target icon is used to indicate other terminals in the group except the first terminal or a public space, where the public space is used for the terminals in the group to share data; The acquisition module 803 is used to acquire the data to be sent, save the data to be sent as a temporary file, and display an icon of the temporary file; A receiving module 804, configured to receive a first operation; The responding module 805 is configured to respond to the first operation by dragging the icon of the temporary file to the target icon, so as to send the temporary file to other terminals or a public space in the group indicated by the target icon except the first terminal.

[0090] In the embodiment of the present invention, the response module 805 may be used to: In response to the first operation, the icon of the temporary file is dragged to the icon of the second terminal to send the temporary file to the second terminal.
