Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a flowchart of a method for data transmission between terminals according to an embodiment of the present invention. Referring to fig. 1, a method for data transmission between terminals includes:
step 101: and receiving login operation data of the receiving terminal. Before data transmission, a receiving terminal needs to log in a data transmission system in the application. Specifically, in the application, the interaction between the receiving terminal and the server is realized between the data transmission system and the receiving terminal through the data transmission website, and the process that the user opens the website of the website at the receiving terminal is regarded as the login process of the receiving terminal.
Step 102: after the receiving terminal successfully logs in, sending a preset first Identity (ID) to the receiving terminal, and receiving first coding information fed back by the receiving terminal; the first encoded information includes the first identity ID and launch data to launch a data transfer application.
Step 103: and generating the first identity identifier according to the first coding information and sending the first identity identifier to the receiving terminal. After receiving the first encoded information, the server generates a corresponding first identity identifier according to the first identity ID in the first encoded information and the start data for starting the data transmission application, and then returns the first identity identifier to the receiving terminal. When the application is actually developed, the identity mark can be a two-dimensional code, a small program code and the like, when the two-dimensional code is generated, the starting data for starting the data transmission application is an application website, the data transmission application of a website is developed by using the patent, and the webpage version data transmission application can be started by using the program scanning capable of opening the webpage application; when the applet codes are generated, the starting data for starting the data transmission application are the applet appid and the applet page path distributed by the applet service provider, the data transmission application of one applet is developed by using the patent, and the applet application can be opened by scanning the applet codes by using the app scanning function which can open the corresponding applet. The actual use depends on the scene.
When a receiving terminal logs in a data transmission website, the identity of the receiving terminal can be automatically displayed, and any terminal can establish communication connection with the receiving terminal by scanning the identity to transmit data between terminals.
Step 104: and receiving login request data of the sending terminal.
Step 105: and after the sending terminal successfully logs in, receiving the data to be transmitted sent by the sending terminal and a first identity ID obtained by identifying and analyzing the first identity. Here, the data storage address in the data to be transmitted may be uploaded to the cloud storage server on site, or may be uploaded to the cloud storage server; the first identity ID can be a pairing record which is stored locally after code scanning or stored in a device pairing table preset by a server through identification and analysis; the first identity identifier identified and analyzed by the sending terminal can be of various types, and can be identified and analyzed through code scanning according to the situation, wherein the first identity identifier is an equipment readable code such as a bar code, a two-dimensional code, a small program code and the like; how to scan the first identity mark by the sending terminal can utilize the scanning function in the existing software to scan, such as the scanning function of mobile phone WeChat or mobile phone QQ or mobile phone browser, and can also utilize the functions of camera shooting and the like carried by the terminal equipment to realize the scanning or identification and analysis of codes, and the specific mode can be determined according to the actual situation.
Step 106: and sending the data to be transmitted to a receiving terminal corresponding to the first identity ID. After the sending terminal logs in the data transmission website by scanning the first identity identifier, the sending terminal selects data to be sent on site or selects data which is uploaded in cloud storage to be sent, and then the function that the sending terminal sends the data to the receiving terminal is achieved.
Specifically, in step 106, when data is sent, four operations are performed, where the first operation is to upload data to the cloud storage server, the second operation is to store an address of the data in the cloud storage in the data transmission record to be received, the third operation is to send the data transmission record to be received to the receiving terminal, and the fourth operation is to request, by the receiving terminal, to download and receive the data according to the data storage address in the record. It should be noted here that the first operation and the second operation may not be performed in a short and continuous time, may be uploaded to cloud storage without being transmitted to a receiving end, and may select data uploaded in cloud storage to be transmitted to the receiving end without being uploaded on site, and the data storage address in the second operation may be obtained in two cases, one is the data storage address directly returned by the cloud storage server after successful uploading on site in real time, and the other is the data storage address returned by the cloud storage server after being manually selected by a user.
In the above embodiment, the first identity identifier is allocated to the receiving terminal, and then the sending terminal scans the first identity identifier displayed by the receiving terminal through the code scanning function to achieve data sending and receiving. In the data transmission process between the terminals of the embodiment, data transmission is achieved without other hardware equipment, and data transmission can be achieved only by scanning the identity shown by the data transmission application opened on the browser of the receiving terminal by the application capable of opening the webpage application after code scanning through the sending terminal, so that the operation steps of data transmission between the terminals are greatly simplified, and the data transmission efficiency between the terminals is greatly improved.
On the basis of the above embodiment, further, in the present application, the sending terminal also displays the identifiable identity, and the sending terminal may also be used as a receiving terminal to receive data at the same time, and the specific operations are as follows:
after the sending terminal successfully logs in, sending a preset second Identity (ID) to the sending terminal, and receiving second coding information fed back by the sending terminal; the second encoding information comprises the second identity ID and starting data for starting a data transmission application; and generating the second identity according to the second coding information and sending the second identity to the sending terminal.
The server sends the second identity to the sending terminal through the steps, and when other terminals send data to the sending terminal, the second identity can be directly identified. The functions of the receiving terminal and the sending terminal are not unique, the receiving terminal can be used as a sending terminal to send data, and the sending terminal can also be used as a receiving terminal to receive data. The specific end needs to be determined according to actual conditions and user requirements.
Further, on the basis of the above embodiment, the present application further discloses the following embodiment, in which mutual transmission between two terminals is realized according to the device pairing record, and the paired devices are directly sent from the device pairing record without scanning codes, specifically as follows:
creating a pairing record: in the application, the server also can construct a preset device matching table of a database, and store the first identity ID and the second identity ID into the device matching table. When the sending terminal successfully identifies and analyzes the first identity displayed by the receiving terminal, the first identity ID and a starting instruction for starting the data transmission application are obtained, the analyzed starting instruction for starting the data transmission application is executed at the sending terminal, the second identity ID allocated by the server is obtained after the application is started and automatically logs in successfully, when the sending terminal obtains the second identity ID, data such as the identity ID and the like are triggered to be stored into a preset equipment pairing table, an equipment pairing record is created, and the two identity IDs of the first identity ID and the second identity ID are respectively stored into two identity ID fields.
Obtaining a pairing record: both the receiving terminal and the sending terminal use their own identity ID as a condition, and autonomously monitor the inquiry or manually inquire the equipment to match any one of the two identity ID fields in the table, so as to find the record, and obtain their own identity ID and the other identity ID on the record, as can be seen from the step 105 in the embodiment of fig. 1, as long as the identity ID of the other party is obtained, data can be sent to the other party. Because the device matches the table, the sending terminal and the receiving terminal are both in autonomous monitoring inquiry or manual inquiry and accord with the own pairing record, the identity ID of the other terminal can be obtained when any terminal inquires the pairing record, and the receiving terminal can be exchanged to be used as the sending terminal role to carry out sending operation. Correspondingly, the problem that a certain terminal does not have code scanning capability and can also be used as a sending terminal, for example, in a scene that a desktop computer sends a mobile phone, the mobile phone scans a code to trigger and create a pairing record, the desktop computer obtains the pairing record, and data can be sent to the mobile phone by using the identity ID of the mobile phone in the pairing record; correspondingly, the problem that if one terminal obtains one or more pairing records, the paired devices do not need to scan codes any more and can also carry out data transmission is solved.
Sending data by using the identity ID in the pairing record: and constructing a data transmission table to be received of the database, storing the first identity ID, the second identity ID and the data storage address into the data transmission table to be received, and creating a record in the data transmission table to be received when the data transmission table is used for sending operation. And the first identity ID is obtained by analyzing the pairing record by the sending terminal and is stored in the identity ID of the receiving party. And the second identity ID is distributed to the sending terminal by the server for use and is stored in the ID field of the sending party. The data storage address is returned by the cloud storage server, and the data storage address is returned in two modes, namely, the data storage address is directly returned by the server after the on-site real-time uploading is successful, and the data file uploaded at the cloud end is manually selected by a user, and the data storage address is returned by the server. And the receiving terminal autonomously monitors and inquires or artificially inquires the ID field of the receiver in the data transmission table to be received by taking the first identity ID of the receiving terminal as a condition, searches the record to be received, further obtains the second identity ID of the sending terminal on the record and the data storage address sent by the sending terminal, and realizes the downloading and receiving of the data according to the data storage address.
