[0034] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0035] The file transfer method provided by the embodiments of the present application can be applied to an application environment as shown in Figure 1 . Among them, the local device 102 and the target device 106 can directly transfer files. For example, files can be transferred based on the direct connection function of the wireless local area network or the wireless local area network hotspot between two devices, or files can be transferred by simultaneously connecting to the wireless local area network provided by the third-party device 104, or files can be transferred through the cloud based on the mobile communication network. The present application embodiments do not make specific limitations on the network channel for file transfer between the local device 102 and the target device 106. The local device 102 and the target device 106 can be but are not limited to various personal computers, laptop computers, smart phones, and tablet computers. The third-party device 104 can be but are not limited to various routers, personal computers, laptop computers, smart phones, and tablet computers.
[0036] In an exemplary embodiment, as shown in Figure 2 , a file transfer method is provided. Taking the local device in Figure 1 as an example, the method includes the following steps 202 to 206. Among them:
[0037] S202. When the wireless local area network (WLAN) function of the local device is enabled and a target device is scanned within a preset range based on the WLAN provided by the local device, transfer a file to the target device through the direct connection function based on the WLAN provided by the local device.
[0038] Among them, the wireless local area network is a wireless communication technology used to establish a local area network based on radio waves within a limited range. For example, a WLAN between the local device and the target device can be constructed based on the WIFI function or the Bluetooth function; the direct connection function means that in the WLAN, a direct point-to-point connection can be established between the local device and the target device without forwarding or routing through a central network device. For example, the direct connection function can be the WIFI direct connection function or the Bluetooth direct connection function. When the target device is scanned by the WLAN provided by the local device, it indicates that the target device has the direct connection function.
[0039] Specifically, after the WLAN function of the local device is enabled, the device identifiers of all devices that have enabled the corresponding WLAN function within the preset range can be scanned based on the application installed on the local device. If the device identifiers include the device identifier of the target device, send the file to be transferred to the target device based on the device identifier of the target device and the direct connection function of the corresponding WLAN.
[0040] S204. When the WLAN function of the local device is not enabled or the target device is not scanned within the preset range based on the WLAN constructed by the local device, obtain the address information of the target device.
[0041] Among them, the address information refers to the location identifier of the target device in the network. For example, the address information can be the IP address of the target device.
[0042] The situation where the target device is not scanned may be one of the following two cases. One case is that the target device does not have the corresponding WLAN function, and the other case is that although the target device has the corresponding WLAN function, it is not enabled.
[0043] S206. When it is determined based on the address information that both the local device and the target device are connected to the WLAN provided by the same third-party device, initiate a request to establish a first data transfer connection to the target device based on the WLAN provided by the third-party device. After the first data transfer connection is established, transfer a file to the target device.
[0044] Among them, the data transmission connection can be established based on a network transmission protocol. For example, the network transmission protocol can be the Transmission Control Protocol or the User Datagram Protocol. After the first data transmission connection is established, the local device can transmit files to the target device based on the peer-to-peer network of WebRTC (Web Real-Time Communication). The method of transmitting files to the target device can also be other methods, which are not specifically limited in the embodiments of the present application.
[0045] Specifically, after the local device sends a connection establishment request for the first data transmission connection to the target device, if the target device returns a corresponding connection establishment response to the local device, the local device and the target device establish a data transmission connection based on the network transmission protocol.
[0046] In the above file transmission method, the local device and the target device can directly establish a connection without a network router or the Internet through the direct connection function, so as to perform the transmission of large-capacity files efficiently and quickly. When the local device and the target device are connected to the wireless local area network provided by the same third-party device, file transmission can be achieved at a farther distance, and the file transmission process is more stable. When the local device cannot transmit files to the target device based on the direct connection function, it automatically selects to use the wireless local area network provided by the third-party device to transmit files to the target device, which can avoid the situation that once the file transmission fails due to a single network channel, the entire file transmission process cannot proceed normally, thus making the file transmission process more secure.
[0047] In some embodiments, the above method further includes: when it is determined based on the address information that the local device and the target device are not connected to the wireless local area network provided by the same third-party device, obtaining the hotspot information of the wireless local area network hotspot provided by the target device, connecting to the wireless local area network hotspot provided by the target device according to the hotspot information, and initiating a connection establishment request for the second data transmission connection to the target device based on the wireless local area network hotspot of the target device. When the second data transmission connection is successfully established, files are transmitted to the target device.
[0048] Among them, the wireless local area network hotspot refers to a device or service that provides a wireless network connection within a specific area through wireless network technology. The hotspot information refers to the network connection information provided by the device when it is a wireless network hotspot. The target device can also connect to the wireless local area network hotspot provided by the local device based on the hotspot information of the local device.
[0049] When the local device and the target device are not connected to the wireless local area network provided by the same third-party device, the two devices cannot establish the first data transmission connection.
[0050] In this embodiment, when the local device and the target device are not connected to the wireless local area network provided by the same third-party device, the local device sends a file to the target device by connecting to the wireless local area network hotspot of the target device. In this way, the network channels for file transmission are more diversified, which can more effectively ensure the file transmission process. And in this process, the two devices directly establish wireless communication without relying on other network devices or Internet connections, which is simple and easy to use and has a high transmission efficiency.
[0051] In some embodiments, the above method further includes: when the wireless local area network hotspot provided by the target device fails to be successfully connected, or the second data transmission connection fails to be established, transmitting the file to the target device based on the cloud.
[0052] Among them, the local device uploads the file to be transmitted to the file storage database located in the cloud, and the target device downloads the corresponding file to be transmitted from the file storage database. The file storage database can be a cstore (Columnar Store, a column storage method) database, or it can be other databases. The embodiments of the present application do not make specific limitations on this.
[0053] In this embodiment, when all other wireless local area network communication methods fail, transmitting the file to the target device based on the cloud makes the transmission process of the file to be transmitted more secure.
[0054] In some embodiments, as Figure 3 shown, transmitting the file to the target device based on the cloud includes:
[0055] S302. Upload the file to be transmitted to the cloud through the mobile communication network and establish a signaling channel with the target device.
[0056] S304. Based on the signaling channel, send a download notification message to the target device so that the target device downloads the file to be transmitted from the cloud based on the mobile communication network.
[0057] Among them, before transmitting the file to be transmitted to the target device based on the cloud, two channels can be established based on the mobile communication network. One channel is the data channel for transmitting the file to be transmitted, and the other is the signaling channel for sending transmission instructions to the target device.
[0058] Specifically, the local device sends a download notification message to the target device through the signaling channel based on the mobile communication network, and uploads the file to be transmitted to the file storage database in the cloud. After receiving the download notification message, the target device downloads the file to be transmitted from the file storage database and returns a download success message to the local device.
[0059] In this embodiment, the local device first uploads the file to be transmitted to the cloud, and then notifies the target device to download the file to be transmitted from the cloud. Storing the file in the cloud first can avoid the loss of the file to be transmitted and ensure the security of the transmission process.
[0060] In some embodiments, the process of obtaining at least one of the hotspot information or the address information includes: in response to a scanning operation on the encoded image displayed on the target device, obtaining at least one of the hotspot information or the address information carried by the encoded image.
[0061] Among them, the encoded image refers to a way of encoding and representing the information of the device in the form of an image. For example, the encoded image can be a QR code or a barcode of the device, and the encoded image can be located on the display screen of the target device.
[0062] In this embodiment, by scanning the encoded image, the hotspot information and address information of the target device can be accurately and quickly obtained, so that the subsequent process of file transmission based on the wireless local area network hotspot provided by the target device and file transmission based on the wireless local area network provided by the third-party device is more efficient.
[0063] In some embodiments, the scanning entry of the scanning operation is an application installed on the local device or a web application provided by the application installed on the local device.
[0064] Among them, the web application refers to an application program running on the Internet, which can be accessed through a browser and displayed in a web page. For example, the web application can be a small program in the application installed on the local device.
[0065] In this embodiment, using the application installed on the local device or the web application provided by the application installed on the local device as the scanning entry of the scanning operation can provide multiple scanning methods for the users of the local device, avoid the failure to obtain the hotspot information and address information of the target device after the failure of a single scanning method, and can more effectively ensure the process of obtaining the hotspot information and address information.
[0066] In one embodiment, as Figure 4 and Figure 5 shown, another file transmission method is provided, where Figure 4 is a method for file transmission based on the application on the local device, Figure 5 is a method for file transmission based on the web application provided by the application, Figure 4 The method in
[0067] (1)When the user opens the application (APP) on the local device, the application will perform a network check. If the check result shows that the local device has WiFi enabled and the target device has the dual-network card WiFi direct connection function, the device identifier of the target device will be scanned by the local device and displayed in the nearby device list near the top of the application. At this time, when the local device enters the file transfer function, it can directly select a file for point-to-point WiFi direct connection transfer. Among them, the local device can be a mobile terminal, and the target device can be a PC terminal.
[0068] (2)If the device identifier of the target device is not in the nearby device list and the user does not find the target device after manually scanning on the local device, it means that the target device does not meet the WiFi direct connection conditions. At this time, if the user clicks on the file transfer function on the local device, the local device will guide the user to scan the QR code on the target device.
[0069] (3)The application will attempt to establish a TCP connection through the network IP information attached to the QR code. If the connection is successful, it will then attempt to establish a connection through the peer-to-peer network of webrtc. After the user selects a file, the file can be directly transferred. Among them, a successful TCP connection means that the local device and the target device are connected to the WIFI hotspot of the same third-party device.
[0070] (4)If the TCP connection fails, the application will attempt to connect to the hotspot of the target device based on the WiFi hotspot information of the target device attached to the QR code. If the connection is successful, the subsequent process is the same as above.
[0071] (5)If the WiFi hotspot of the target device cannot be connected successfully either, after the user selects the file transfer function, the file will be transferred through the mobile communication network based on the cloud file storage database.
[0072] Figure 5 The method in
[0073] (1)The user opens the mini-program provided by the application on the local device and uses the mini-program to scan the QR code displayed on the target device. After entering the mini-program, it will attempt to establish a local area network connection through the network address information of the target device attached to the QR code.
[0074] (2)If the connection is successful, it will then attempt to establish a connection through the peer-to-peer network of webrtc. After the user selects a file, the file can be directly transferred.
[0075] (3) If a local area network connection cannot be established, or the WebRTC peer-to-peer network fails to be established, after the user selects a file on the local device, the file will be uploaded to the csotre file server first, and the applet will notify the target device to download the corresponding file from the csstore file server through the signaling of the HTTP interface. This process can be completed based on the mobile communication network.
[0076] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are sequentially shown according to the indications of the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same time, but can be executed at different times.
