[0076] In the following description of the present application, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0077] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0078] In order to improve the success rate of data transmission, the embodiments of the present application provide a data transmission method, a data transmission device, an electronic device, a computer-readable storage medium, and a computer program product. The data transmission method can be executed by the data transmission device, or by an electronic device integrated with the data transmission device; the data transmission method can be executed by the data transmission device, or by an electronic device integrated with the data transmission device.

[0079] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0080] Please refer to Figure 1 , the present application also provides a data transmission system, such as Figure 1 As shown, the data transmission system includes a first electronic device 100 and a second electronic device 200. The first electronic device 100 is integrated with the data transmission device provided by the present application, and the second electronic device 200 is integrated with the data transmission device provided by the present application.

[0081] Among them, the first electronic device 100 can be any device equipped with a processor and has processing capabilities, such as mobile electronic devices with processors such as smart phones, tablet computers, PDAs, laptops, smart speakers, or fixed electronic devices with processors such as desktop computers, televisions, servers, industrial equipment, etc.

[0082] Among them, the second electronic device 200 can be any device equipped with a processor and has processing capabilities, such as mobile electronic devices with processors such as smart phones, tablet computers, PDAs, laptops, smart speakers, or fixed electronic devices with processors such as desktop computers, televisions, servers, industrial equipment, etc.

[0083] In a specific embodiment, the first electronic device 100 is a vehicle-mounted terminal, and the second electronic device 200 is a mobile terminal. In another specific embodiment, the first electronic device 100 is a desktop computer, and the second electronic device 200 is a mobile terminal. In yet another specific embodiment, the first electronic device 100 is a television, and the second electronic device 200 is a mobile terminal.

[0084] In addition, the data transmission system may further include a memory for storing original data, intermediate data and result data.

[0085] In the embodiment of the present application, the memory may be a cloud memory. Cloud storage is a new concept extended and developed from the concept of cloud computing. A distributed cloud storage system (hereinafter referred to as the storage system) refers to a storage system that uses cluster applications, grid technology, and distributed storage file systems to bring together a large number of storage devices of various types (storage devices are also called storage nodes) in the network through application software or application interfaces to work together and provide external data storage and business access functions.

[0086] At present, the storage method of the storage system is: create a logical volume, and when creating a logical volume, allocate physical storage space for each logical volume. The physical storage space may be composed of disks of a storage device or several storage devices. The client stores data on a logical volume, that is, stores the data on the file system. The file system divides the data into many parts, each of which is an object. The object contains not only data but also additional information such as data identification (ID, ID entity). The file system writes each object into the physical storage space of the logical volume, and the file system records the storage location information of each object, so that when the client requests to access the data, the file system can allow the client to access the data according to the storage location information of each object.

[0087] The process of the storage system allocating physical storage space to a logical volume is as follows: based on the estimated capacity of the objects stored in the logical volume (this estimate often has a large margin relative to the actual capacity of the objects to be stored) and the grouping of independent redundant disk arrays (RAID, Redundant Array of Independent Disks), the physical storage space is pre-divided into stripes. A logical volume can be understood as a stripe, thereby allocating physical storage space to the logical volume.

[0088] It should be noted that Figure 1 The scenario diagram of the data transmission system shown is merely an example. The data transmission system and scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the data transmission system and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is equally applicable to similar technical problems.

[0089] It should be noted that the serial numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

[0090] Please refer to Figure 2 , Figure 2 is a flow chart of a first embodiment of a data transmission method provided in an embodiment of the present application, such as Figure 2 As shown, the process of the data transmission method provided by this application is as follows:

[0091] 201. When receiving a connection request from a target application based on data to be connected sent by a second device, determine whether the data to be connected is encrypted data.

[0092] Among them, the application type of the target application can be music radio applications, video playback applications, social communication applications, news reading applications, game applications, online shopping applications, travel applications, financial management applications, conference applications, utility applications, office software applications, education and learning applications, medical and health applications, system optimization applications, life and entertainment applications and other application types. The data to be continued is the data that the target application needs to continue to the first device. For example, the target application is a video playback application A of the video playback type, and the data to be continued includes the playback information of the currently playing video. The video playback information includes: video number, video title, video network address, video playback progress, video introduction information, video cover, etc.

[0093] The connection request of the target application based on the data to be connected includes data attribute information of the data to be connected and application attribute information of the target application.

[0094] The data attribute information of the data to be continued includes the encryption attribute, data format and data type of the data to be continued. The encryption attribute of the data to be continued is represented by the encryption attribute field, for example, the encryption attribute field is boolencrypted. If the value of bool encrypted is 1, it means that the encryption attribute of the data to be continued is encrypted type data, and if the value of bool encrypted is 0, it means that the encryption attribute of the data to be continued is unencrypted type data. The data type of the data to be continued can be JSON string, Protobuf, FlatBuffers, bit array, etc.

[0095] The application attribute information of the target application includes the application name, application package name, application string version number, application digital version number, application type, etc. of the target application.

[0096] In a specific embodiment, the format of the connection request for the data to be connected is as follows:

[0097]

[0098]

[0099] In the embodiment of the present application, after the user clicks the target application on the second device, the second device obtains the data attribute information of the data to be continued and the application attribute information of the target application. A connection request is generated according to the data attribute information of the data to be continued and the application attribute information of the target application, and the first device obtains the connection request.

[0100] 202. If the data to be continued is not encrypted data, determine whether a local application of the same type as the target application is installed on the first device.

[0101] In the embodiment of the present application, if the data to be continued is not encrypted data, the application type of the target application is obtained, and it is determined whether a local application of the same application type as the target application is installed on the first device.

[0102] For example, if the target application is video playback application A, and video playback application B is installed on the first device, and video playback application A and video playback application B belong to the same video playback application category, then it is determined that a local application of the same type as the target application is installed on the first device.

[0103] 203. If a local application of the same type as the target application is installed on the first device, a connection indication message is returned to the second device.

[0104] The connection indication information is used to instruct the second device to send the data to be connected to the first device.

[0105] In an embodiment of the present application, if a local similar application of the same application type as the target application is installed on the first device, indicating that the target application can be continued through the local similar application on the first device based on the data to be continued, then a connection indication information is returned to the second device, and the connection indication information is used to instruct the second device to send the data to be continued to the first device.

[0106] 204. When receiving the data to be continued returned by the second device to the first device, use a local application of the same type to load the data to be continued.

[0107] In a specific embodiment, when the to-be-connected data returned by the second device to the first device is received, a local application of the same type is run in the foreground and the to-be-connected data is loaded.

[0108] Please refer to Figure 3 , Figure 3 is a flow chart of a second embodiment of a data transmission method provided in an embodiment of the present application. The data transmission method provided in the present application is applied to a first device, such as Figure 3 As shown, the process of the data transmission method provided by this application is as follows:

[0109] 301. Detect whether a connection request of a target application based on data to be connected, sent by a second device, is obtained.

[0110] In the embodiment of the present application, a preset detection period is used to detect whether a connection request based on the data to be connected issued by the second device is obtained by the target application, wherein the preset detection period can be 1s, 2s, etc., depending on the specific setting.

[0111] 302. Determine whether a local application with the same application name as the target application is installed on the first device.

[0112] In the embodiment of the present application, when a connection request based on the to-be-connected data of the target application sent by the second device is received, it is determined whether a local application with the same application name as the target application is installed on the first device. Specifically, the application names of each local application on the first device are obtained, and the application names of each local application on the first device are matched with the application name of the target application respectively, to determine whether a local application with the same application name as the target application is installed on the first device.

[0113] In the embodiment of the present application, if the first device does not have a local application with the same name as the target application installed, it is necessary to determine whether the data to be continued can be loaded by a local application of the same type on the first device, and then execute 303: determine whether the data to be continued is encrypted data. If the first device has a local application with the same name as the target application installed, it is necessary to further determine whether the local application with the same name is compatible with the target application, and then execute 306: determine whether the local application with the same name is compatible with the target application.

[0114] 303. Determine whether the data to be continued is encrypted data.

[0115] If no local application with the same application name as the target application is installed on the first device, it is determined whether the data to be continued is encrypted data.

[0116] 304. Determine whether a local application of the same type as the target application is installed on the first device.

[0117] If the data to be continued is not encrypted data, it is determined whether the local application of the same type has the authority to load the data to be continued. If the data to be continued is encrypted data, it ends and returns end indication information to the second device, wherein the end indication information is used to instruct the second device to end the connection.

[0118] 305. Determine whether a local application of the same type has permission to load the data to be continued.

[0119] In a specific embodiment, the data to be continued is video playback information. The video number of the data to be continued is obtained, and it is determined whether the media resource library of the local similar application contains the video number of the data to be continued. If the media resource library of the local similar application contains the video number of the data to be continued, it means that the local similar application has the authority to load the data to be continued. If the local similar application has the authority to load the data to be continued, the local similar application is used to load the data to be continued. If the local similar application does not have the authority to load the data to be continued, the process ends and an end indication message is returned to the second device, wherein the end indication message is used to instruct the second device to end the connection.

[0120] 306. Determine whether the local application with the same name is compatible with the target application.

[0121] In an embodiment of the present application, if a local application with the same application name as the target application is not installed on the first device, the local application of the same type has the permission to load the data to be continued, and the compatible version number range of the local application with the same name and the version number of the target application are obtained. If the version number of the target application belongs to the compatible version number range of the local application with the same name, it is determined that the local application with the same name is compatible with the target application.

[0122] Further, if the local application with the same name is compatible with the target application, the to-be-connected number is loaded using the local application with the same name; if the local application with the same name is not compatible with the target application, S304 is executed: determining whether a local application of the same type as the target application is installed on the first device.

[0123] 307. Return connection indication information to the second device.

[0124] In the embodiment of the present application, if the local application with the same name is not compatible with the target application, the connection indication information is returned to the second device; if the local application with the same name is compatible with the target application, the data to be continued is loaded using the local application with the same name. If the local application of the same type has the authority to load the data to be continued, the connection indication information is returned to the second device; if the local application of the same type does not have the authority to load the data to be continued, the connection is terminated and the termination indication information is returned to the second device, wherein the termination indication information is used to instruct the second device to terminate the connection.
