As shown in fig. 1, the present invention provides a file sharing method, which is applied to an electronic whiteboard, does not need hardware support, is convenient to operate, overcomes geographical limitation, and realizes fast sharing of files of the electronic whiteboard.
Specifically, the file sharing method comprises the following steps:
step S1, receiving a code scanning sharing instruction, and generating a code scanning sharing page according to the code scanning sharing instruction; the code scanning sharing instruction is triggered through an electronic whiteboard interface or sent by a mobile terminal. And clicking and triggering a display menu page of the electronic whiteboard through a code scanning button in the menu page. Or the electronic whiteboard can be bound or connected with a certain mobile terminal in advance, and the mobile terminal sends out a code scanning sharing instruction. For example, when the electronic whiteboard is applied to a conference room, a code scanning sharing instruction can be sent by a mobile terminal bound by the conference room.
And after receiving the code scanning sharing command, generating a code scanning sharing page. The code scanning sharing page comprises a loading animation and a two-dimensional code, and the loading animation is generated after a code scanning sharing instruction is received. And the loading animation is finished after the two-dimensional code is generated, and the code scanning shared page displays the two-dimensional code, so that the tedious degree of a user in the process of waiting for the two-dimensional code is reduced, and the use experience of the user is improved.
And step S2, saving a whiteboard file of the electronic whiteboard, wherein the whiteboard file is used for saving all interfaces of the electronic whiteboard. During the use of the electronic whiteboard, there may be a plurality of interfaces, each storing different contents, and all the interfaces of the electronic whiteboard need to be stored. As shown in fig. 2, saving the whiteboard file of the electronic whiteboard specifically includes the following steps:
step S21, creating a designated folder; the appointed folder is a Qrcode folder and is used for storing the whiteboard file.
And S22, acquiring all handwriting of the current interface of the electronic whiteboard, calling a handwriting writing method to draw all the handwriting to a bitmap, storing the bitmap and storing the bitmap to a specified folder according to a preset format. Firstly, all the handwriting of the current interface are obtained, a handwriting writing method drawFull is called, the handwriting is drawn on a bitmap, and the obtained notes comprise pictures, characters, position relations, colors, handwriting thickness and the like. And storing all contents on the bitmap, and storing the bitmap into a Qrcode folder according to a file in a picture format.
And step S23, executing step S22 for multiple times until all interfaces of the electronic whiteboard are saved in a designated folder. And after all interfaces of the electronic whiteboard are stored in the Qrcode folder, packaging and naming the Qrcode folder in a zip compression mode. Generally, this Qrcode folder is named yyyy-MM-dd-HH-MM-ss
And step S3, uploading the whiteboard file to a designated server, receiving file information returned by the designated server, and generating a two-dimensional code according to the file information. After the whiteboard file is generated, the whiteboard file in the zip format is uploaded to a designated server through http, so that the mobile terminal can conveniently acquire the corresponding whiteboard file from the server, and simultaneously backup the whiteboard file, and can directly download the whiteboard file from the designated server when needed subsequently.
And after receiving the whiteboard file, the appointed server returns file information under the condition that the network condition is normal. The file information comprises a url address and a file id. And after the url address and the file id are received, generating a two-dimensional code for the character string of the url address by using a zxing tool library according to the url address of the whiteboard file, and obtaining a bitmap picture of the two-dimensional code. After the two-dimensional code is obtained, hiding the loading animation by the code scanning shared page, and displaying a bitmap picture of the two-dimensional code.
In the process of displaying the two-dimensional code, the method further comprises the following steps:
and step S31, judging whether an encryption instruction is received, when the encryption instruction is received, randomly generating a plurality of digits as digital passwords, establishing a binding relationship between file information and the digital passwords, and encrypting the whiteboard file. The encryption instruction can be triggered by an electronic whiteboard interface or a mobile terminal bound with the electronic whiteboard. Generally, there is a toggle button on the scan sharing page whether it is encrypted or not. When the user selects to encrypt, the encryption is selected through the switch button. And when the encryption command is received, generating a random password and displaying the random password on a code scanning shared page. And binding the file id and the digital password with the designated server in a http request mode, wherein the whiteboard file can be displayed on the mobile terminal only after the correct digital password is received.
S4, displaying the two-dimension code on a code scanning shared page, wherein the two-dimension code is used for sending a display request by the mobile terminal; and when a display request is received, displaying the whiteboard file on the mobile terminal. And displaying the two-dimension code on a code scanning sharing page, wherein the mobile terminal can directly scan the two-dimension code and download the whiteboard file from the designated server, thereby obtaining all handwriting on the electronic whiteboard.
When the whiteboard file is encrypted, the mobile terminal needs to input a digital password after scanning the code. And when the digital password is consistent with the password stored in the appointed server, the whiteboard file displays the content. When the password is incorrect, the content on the whiteboard file cannot be displayed, so that the safety of the whiteboard file transmission process is improved.
