Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In order to solve the above-mentioned problems, referring to fig. 1, fig. 1 is a block diagram of a network resource transmission system according to an embodiment of the present invention, which is a possible application scenario. The network resource transmission system includes: the system comprises a first terminal, a second terminal and a server.

When receiving the resource transmission instruction, the first terminal sends a first request message carrying a terminal identifier of the first terminal to the server.

When a first request message is received, the server generates a target transmission identifier for representing the current resource transmission, records the corresponding relation between the target transmission identifier and the terminal identifier of the first terminal, and sends a first response message carrying the target transmission identifier to the first terminal.

When the first response message is received, the first terminal extracts the target transmission identification from the first response message.

The second terminal obtains the target transmission identification from the first terminal, sends the target network resource to be transmitted to the first terminal to the server, and sends the target transmission identification to the server.

When the target network resource and the target transmission identifier are received, the server determines a first terminal to which the terminal identifier corresponding to the target transmission identifier belongs according to the corresponding relation between the recorded transmission identifier and the terminal identifier, and transmits the target network resource with the first terminal.

Based on the network resource transmission system provided by the embodiment of the invention, the second terminal can acquire the target transmission identifier for representing the current resource transmission from the first terminal, and send the target network resource and the target transmission identifier to be transmitted to the first terminal to the server. After receiving the target network resource, the server may perform transmission of the target network resource with the first terminal. Further, the first terminal may obtain the target network resource from the server. Compared with the prior art, the network resource transmission method provided by the embodiment of the invention has the advantages that the user can manually copy the target network resource from the storage space of the second terminal to the storage space of the first terminal, so that the user operation can be simplified, and the network resource transmission efficiency can be improved.

Referring to fig. 2, fig. 2 is a flowchart of a network resource transmission method provided by an embodiment of the present invention, where the method is applied to a first terminal, and a network resource transmission system to which the first terminal belongs further includes a second terminal and a server, and the method may include the following steps:

s201: and when receiving the resource transmission instruction, sending a first request message carrying the terminal identification of the first terminal to the server.

S202: when a first response message corresponding to the first request message sent by the server is received, extracting a target transmission identifier from the first response message, so that the second terminal sends the target network resource to be transmitted to the first terminal by the second terminal to the server after acquiring the target transmission identifier from the first terminal, and sends the target transmission identifier to the server.

The target transmission identifier is generated by the server when the first request message is received, and is used for representing the transmission identifier of the current resource transmission.

S203: the target network resource is obtained from the server.

Based on the network resource transmission method provided by the embodiment of the invention, the second terminal can acquire the target transmission identifier for representing the current resource transmission from the first terminal, and send the target network resource and the target transmission identifier to be transmitted to the first terminal to the server. After receiving the target network resource, the server may perform transmission of the target network resource with the first terminal. Further, the first terminal may obtain the target network resource from the server. Compared with the prior art, the network resource transmission method provided by the embodiment of the invention has the advantages that the user can manually copy the target network resource from the storage space of the first terminal to the storage space of the second terminal, so that the user operation can be simplified, and the network resource transmission efficiency can be improved.

In step S201, the first terminal may be a desktop computer, the second terminal may be a mobile terminal, for example, the second terminal may be a mobile phone, a tablet computer, or other devices. Alternatively, the first terminal may be installed in a desktop computer in the form of an application program, and the second terminal may be installed in a mobile terminal in the form of a corresponding application program. For example, the first terminal may be an office application installed in a desktop computer, and the second terminal may be a corresponding office application installed in a mobile terminal. The network resources may include video resources, music resources, office documents, and the like.

When the user needs to transmit the network resource stored in the second terminal to the first terminal, the user may input a resource transmission instruction to the first terminal. Correspondingly, when the first terminal receives the resource transmission instruction, a request message (i.e. a first request message) carrying the terminal identifier of the first terminal can be sent to the server. The terminal identification of the first terminal may be represented by a user ID (identification number) of a user currently logged into the first terminal. The user ID of a user may be represented by the user's registered account or by the user's registered phone number, but is not limited thereto.

In one implementation, a "resource transfer" button may be provided in the user interface of the first terminal, and the user may click on the "resource transfer" button to input a resource transfer instruction to the first terminal. Further, the first terminal may send a first request message to the server.

After receiving the first request message, the server may generate a transmission identifier (i.e. a target transmission identifier) for indicating the current resource transmission, and send a response message (i.e. a first response message) carrying the target transmission identifier to the first terminal.

For example, the server may create a room for representing the correspondence between the terminals, and the terminals joining the same room may perform resource transmission with each other, and the target transmission identifier may be a room ID of the room created at this time.

In step S202, after receiving the first response message, the first terminal may extract the target transmission identifier carried in the first response message.

In one embodiment of the present invention, after extracting the target transmission identity from the first response message, the method may further comprise the steps of: and generating and displaying a two-dimensional code for representing the target transmission identifier, so that the second terminal obtains the target transmission identifier based on the two-dimensional code.

In one implementation, the first terminal may generate a two-dimensional code for representing the target transmission identifier, and display the two-dimensional code in a user interface of the first terminal.

Correspondingly, the second terminal can acquire the two-dimensional code displayed by the first terminal and acquire the target transmission identifier represented by the two-dimensional code. For example, the user may call the camera function through the second terminal, scan the two-dimensional code displayed by the first terminal, and decode the two-dimensional code to obtain the target transmission identifier.

Furthermore, the second terminal may send the target transmission identifier to the server, and the network resource to be transmitted to the first terminal at this time (i.e. the target network resource), after the server receives the target network resource and the target transmission identifier, the server may determine, according to the recorded correspondence between the transmission identifier and the terminal identifier, the terminal identifier corresponding to the target transmission identifier, where the first terminal to which the terminal identifier belongs is the terminal that receives the target network resource at this time, and further, the server may perform transmission of the target network resource with the first terminal.

In step S203, in one implementation manner, after determining that the first terminal is the terminal that receives the target network resource, the server may directly send the target network resource to the first terminal, and correspondingly, the first terminal may receive the target network resource sent by the server.

Based on the above processing, the server can directly forward to the first terminal after obtaining the target network resource, so that the transmission time of the network resource can be saved, and further, the transmission efficiency of the network resource can be improved.

In one embodiment of the present invention, before step S203, the method may further include the steps of:

step one, when receiving the reminding message sent by the server, sending a second request message for requesting the target network resource to the server.

And step two, when a second response message corresponding to the second request message sent by the server is received, extracting a resource downloading link carried in the second response message.

Accordingly, step S203 may include the steps of: and obtaining the target network resource from the storage space indicated by the resource download link.

The reminding message is used for reminding the first terminal that the server has acquired the target network resource from the second terminal.

In one implementation manner, after determining that the first terminal is the terminal that receives the target network resource, the server may remind the first terminal that the server has acquired the target network resource from the second terminal. Further, the first terminal may request the server to acquire the target network resource after receiving the alert message.

Correspondingly, after receiving the second request message, the server may send a response message (i.e., a second response message) carrying a resource download link corresponding to the target network resource to the first terminal.

After receiving the second response message, the first terminal may extract the resource download link carried in the second response message.

In one implementation, after extracting the resource download link, the first terminal may directly obtain the target network resource from the storage space indicated by the resource download link.

In another implementation, the first terminal may display the resource download link in the user interface after extracting the resource download link. When the target network resource needs to be acquired, the user can click on the resource downloading link displayed by the first terminal, and then the first terminal can acquire the target network resource from the storage space indicated by the resource downloading link.

The storage space indicated by the resource download link may be a storage space in a server, or may be a storage space of another storage device for storing network resources.

Therefore, after the first terminal acquires the resource downloading link, the first terminal can acquire the target network resource according to the instruction of the user when the user needs, so that the personalized requirement of the user can be met, and the user experience is improved.

In addition, after the target network resource is obtained, if the target network resource is a compressed file, the first terminal may decompress the target network resource to obtain the network resource transmitted at this time.

Referring to fig. 3, fig. 3 is a flowchart of a network resource transmission method provided by an embodiment of the present invention, where the method is applied to a second terminal, and a network resource transmission system to which the second terminal belongs further includes a first terminal and a server, and the method may include the following steps:

s301: and acquiring the target transmission identification from the first terminal.

The target transmission identifier is a transmission identifier obtained by the first terminal from the server and used for representing the current resource transmission.

S302: and sending the target network resource to be transmitted to the first terminal to the server, and sending the target transmission identifier to the server, so that the server determines the first terminal to which the terminal identifier corresponding to the target transmission identifier belongs according to the corresponding relation between the recorded transmission identifier and the terminal identifier after receiving the target network resource and the target transmission identifier, and transmits the target network resource with the first terminal.

Based on the network resource transmission method provided by the embodiment of the invention, the second terminal can acquire the target transmission identifier for representing the current resource transmission from the first terminal, and send the target network resource and the target transmission identifier to be transmitted to the first terminal to the server. After receiving the target network resource, the server may perform transmission of the target network resource with the first terminal. Further, the first terminal may obtain the target network resource from the server. Compared with the prior art, the network resource transmission method provided by the embodiment of the invention has the advantages that the user can manually copy the target network resource from the storage space of the second terminal to the storage space of the first terminal, so that the user operation can be simplified, and the network resource transmission efficiency can be improved.

In one embodiment of the present invention, step S301 may include the steps of:

step 1, acquiring a two-dimensional code displayed by a first terminal.

And step 2, acquiring a target transmission identifier represented by the two-dimensional code.

Wherein the first terminal and the second terminal may be referred to the detailed description in the above embodiments.

In one implementation, when a user needs to transmit a network resource stored in the second terminal to the first terminal, the user may input a resource transmission instruction to the first terminal. Correspondingly, when the first terminal receives the resource transmission instruction, a first request message carrying the terminal identification of the first terminal can be sent to the server.

After receiving the first request message, the server may generate a target transmission identifier for indicating the current resource transmission, and send a first response message carrying the target transmission identifier to the first terminal.

After receiving the first response message, the first terminal may extract the target transmission identifier from the first response message, and then the first terminal may generate and display a two-dimensional code for representing the target transmission identifier.

Correspondingly, the second terminal can acquire the two-dimensional code displayed by the first terminal, and decode the acquired two-dimensional code to obtain the target transmission identifier represented by the two-dimensional code. For example, the user may call the camera function through the second terminal, scan the two-dimensional code displayed by the first terminal, and decode the two-dimensional code to obtain the target transmission identifier.

In step S302, in one implementation, after the second terminal obtains the target transmission identifier, the second terminal may directly send the target transmission identifier to the server, and the target network resource to be transmitted to the first terminal at this time.

Based on the processing, the transmission time of the network resource can be saved, and the transmission efficiency of the network resource can be improved.

In one embodiment of the present invention, step S302 may include the steps of:

step one, a third request message carrying a target transmission identifier is sent to a server.

And step two, when a third response message corresponding to the third request message sent by the server is received, sending the target network resource to the server.

The third response message is used for notifying the second terminal to start the current resource transmission.

In one implementation, after acquiring the target transmission identifier, the second terminal may send a request message (i.e., a third request message) carrying the target transmission identifier to the server, so as to request to start transmitting the target network resource from the server. In addition, the third request message may further carry a terminal identifier of the second terminal, where the terminal identifier of the second terminal may be represented by a user ID of a user currently logged in to the second terminal.

The server may send a third response message to the second terminal after receiving the third request message to inform the second terminal of the transmission target network resource. Further, the second terminal may send the target network resource to the server after receiving the third response message.

After receiving the target network resource, the server can search the corresponding relation between the recorded transmission identifier and the terminal identifier, determine the terminal identifier corresponding to the received target transmission identifier, wherein the first terminal to which the terminal identifier belongs is the terminal for receiving the target network resource, and further, the server can transmit the target network resource with the first terminal.

In one embodiment of the present invention, the method may further comprise the steps of, prior to sending the target network resource to the server: and displaying the resource identification of the alternative network resource.

Accordingly, step S302 may include the steps of: when a resource selection instruction is received, compressing network resources to which the resource identifier indicated by the resource selection instruction in the displayed resource identifiers belongs to, so as to obtain target network resources; and sending the target network resource to the server.

Wherein the alternative network resource may comprise a network resource stored locally by the second terminal. For example, the alternative network resource may be a video resource, a music resource, an office document, etc., stored locally by the second terminal. The resource identifier of the candidate network resource may be a resource name of each candidate network resource, or may be a thumbnail of each candidate network resource, but is not limited thereto.

In one implementation, the second terminal may display the resource identification of the locally stored network resource (i.e., the alternative network resource) after receiving the third response message. Accordingly, the user may browse the resource identifier displayed by the second terminal, and select the resource identifier (may be referred to as a target resource identifier) of the network resource to be transmitted to the first terminal this time.

Correspondingly, the second terminal can determine the target resource identifier selected by the user, obtain the network resource to which the target resource identifier belongs from the local, and then compress the obtained network resource to obtain the compressed network resource (i.e. the target network resource). Further, the second terminal may send the target network resource to the server.

In addition, the second terminal may also directly send the network resource to which the target resource identifier belongs to the server.

In one implementation manner, if the number of network resources to which the target resource identifier belongs is multiple, the second terminal may sequentially send the network resources to which the target resource identifier belongs to the server according to the order in which the user selects the target resource identifier, and after sending the last network resource to the server, the second terminal may further send a reminder message for reminding the server that the current resource transmission is completed to the server.

Referring to fig. 4, fig. 4 is a flowchart of a network resource transmission method provided by an embodiment of the present invention, where the method is applied to a server, and a network resource transmission system to which the server belongs further includes a first terminal and a second terminal, and the method may include the following steps:

s401: when a first request message which is sent by a first terminal and carries a terminal identifier of the first terminal is received, a target transmission identifier for representing the current resource transmission is generated.

S402: and recording the corresponding relation between the target transmission identifier and the terminal identifier of the first terminal, and sending a first response message carrying the target transmission identifier to the first terminal so that the first terminal provides the target transmission identifier for the second terminal.

S403: when receiving a target network resource and a target transmission identifier, which are sent by a second terminal, the second terminal transmits the target network resource and the target transmission identifier to the first terminal, determining the first terminal to which the terminal identifier corresponding to the target transmission identifier belongs according to the corresponding relation between the recorded transmission identifier and the terminal identifier, and transmitting the target network resource with the first terminal.

In step S401, when the user needs to transmit the network resource stored in the second terminal to the first terminal, the user may input a resource transmission instruction to the first terminal. When the first terminal receives the resource transmission instruction, a first request message carrying a terminal identifier of the first terminal can be sent to the server.

Accordingly, after receiving the first request message, the server may generate a transmission identifier (i.e., a target resource transmission identifier) for indicating the current resource transmission. For example, the server may create a room for representing the correspondence between the terminals, and the terminals joining the same room may perform resource transmission with each other, and the target transmission identifier may be a room ID of the room created at this time.

In step S402, the server may further extract the terminal identifier of the first terminal carried in the first request message, record the correspondence between the target transmission identifier and the terminal identifier of the first terminal, and then send a response message (i.e., the first response message) carrying the target transmission identifier to the first terminal.

After receiving the first response message, the first terminal can extract the target transmission identifier carried in the first response message and provide the target transmission identifier for the second terminal. Correspondingly, the second terminal can acquire the target transmission identifier from the first terminal, and further, the second terminal can send the target transmission identifier and the target network resource to be transmitted to the first terminal to the server.

In step S403, after receiving the target network resource, the server may store the target network resource locally, or the server may store the target network resource in another storage device for storing network resources.

In one embodiment of the present invention, step S403 may include the steps of:

step 1, when a third request message carrying a target transmission identifier and sent by a second terminal is received, a third response message corresponding to the third request message is sent to the second terminal.

And step 2, when receiving the target network resource to be transmitted to the first terminal by the second terminal according to the third response message, determining the first terminal to which the terminal identifier corresponding to the target transmission identifier belongs according to the corresponding relation between the recorded transmission identifier and the terminal identifier.

In one implementation, after acquiring the target transmission identifier, the second terminal may send a request message (i.e., a third request message) carrying the target transmission identifier to the server, so as to request to start transmitting the target network resource from the server.

After receiving the third request message, the server may send a third response message to the second terminal to inform the second terminal to start transmitting the target network resource. Correspondingly, after receiving the third response message, the second terminal may send the target network resource to be transmitted to the first terminal to the server.

After receiving the target network resource, the server can search the corresponding relation between the locally recorded transmission identifier and the terminal identifier, determine the terminal identifier corresponding to the received target transmission identifier, and further, the server can determine the first terminal to which the terminal identifier belongs, namely the terminal receiving the target network resource.

In one implementation, after determining that the first terminal is the terminal that receives the target network resource, the server may directly send the target network resource to the first terminal. Accordingly, the first terminal may receive the target network resource.

In one embodiment of the present invention, step S403 may include the steps of:

Step one, a reminding message is sent to a first terminal.

Step two, after receiving a second request message for requesting the target network resource sent by the first terminal, sending a second response message carrying a resource download link of the target network resource to the first terminal, so that the first terminal extracts the resource download link carried in the second response message after receiving the second response message; and obtaining the target network resource from the storage space indicated by the resource download link.

In one implementation, after determining the first terminal that receives the target network resource, the server may further remind the first terminal that the server has acquired the target network resource from the second terminal. Correspondingly, after receiving the reminding message, the first terminal can request the server to acquire the target network resource.

After receiving the second request message, the server may determine a storage space storing the target network resource and generate a resource download link for representing the storage space, and then the server may send a response message (i.e., a second response message) carrying the resource download link to the first terminal.

Correspondingly, after receiving the second response message, the first terminal may download the storage space indicated by the link from the resource carried in the second response message, and acquire the target network resource. The method for the first terminal to acquire the target network resource may be described in detail in the above embodiment.

Referring to fig. 5, fig. 5 is a flowchart of an example of a network resource transmission method according to an embodiment of the present invention, where the method may include the following steps:

s501: when receiving the resource transmission instruction, the first terminal sends a first request message carrying a terminal identifier of the first terminal to the server.

S502: when the first request message is received, the server generates a target transmission identifier for representing the current resource transmission, and records the corresponding relation between the target transmission identifier and the terminal identifier of the first terminal.

S503: the server sends a first response message carrying the target transmission identification to the first terminal.

S504: when the first response message is received, the first terminal extracts the target transmission identification from the first response message and displays the target transmission identification in the form of a two-dimensional code.

S505: the second terminal obtains the two-dimension code displayed by the first terminal and obtains the target transmission identification represented by the two-dimension code.

S506: and the second terminal sends a third request message carrying the target transmission identification to the server.

S507: and when the third request message is received, the server sends a third response message corresponding to the third request message to the second terminal.

And S508, when the third response message is received, the second terminal sends the target network resource to be transmitted to the first terminal to the server.

S509: when receiving the target network resource, the server determines a first terminal to which the terminal identifier corresponding to the target transmission identifier belongs according to the corresponding relation between the recorded transmission identifier and the terminal identifier.

S5010: and the server sends a reminding message to the first terminal.

S5011: when the reminding message is received, the first terminal sends a second request message to the server.

Wherein the second request message is for requesting the target network resource from the server.

S5012: and when the second request message is received, the server sends a second response message carrying a resource downloading link corresponding to the target network resource to the first terminal.

S5013: and when the second response message is received, the first terminal extracts the resource downloading link carried in the second response message.

S5014: and the first terminal acquires the target network resource from the storage space indicated by the resource download link.
