in step S12, optionally, the mobile terminal first logs in to complete user authentication with the server, and then obtains the download record list of the user from the server. In this step, if the mobile terminal logs in, the server binds the unique download session code and the download record, and at the same time, binds the user. Of course, this step may not be performed by user login, that is, all the downloaded log files of the server may be shared by all users.
In step S12, the mobile terminal may optionally download the download record from the server and display it on the mobile terminal. Due to the limitation of the size of the display screen of the mobile terminal, when the download record is displayed on the mobile terminal, only the thumbnail of the download record can be displayed, namely, the summary information of the download record can be browsed on the mobile terminal, so that a user can conveniently check the download record at any time and any place.
S13: the display device downloads the download record from the server according to the unique download session code.
In step S13, the display apparatus transmits a package requesting a download record to the server, the package containing the unique download session code. If the download record corresponding to the unique download session code is bound on the server, the server can send the download record to the display device according to the unique download session code; otherwise, the server does not return or return the unbound information to the display device, and the display device needs to resend the data packet requesting for downloading the record to the server at this moment. The retransmission is performed at regular intervals (e.g., 1 second).
S14: the display device displays the download record.
In step S14, the display device opens the download record and displays the content of the download record for the user to view, thereby enabling the record file download to be shared on different display devices.
In the embodiment, no additional file service software needs to be installed on the display device, the display device only needs to generate a download two-dimensional code, a user scans the download two-dimensional code through the mobile terminal to identify the unique download session code, selects a download record on the mobile terminal, requests the server to bind the unique download session code and the selected download record, and the display device can request to download the display record stored on the server from the server according to the unique download session code; the technical problem that the file mobility of the display device is inconvenient in the prior art is solved, the display device can download file records from a server at any time and any place, only a function of generating and downloading two-dimensional codes needs to be set on the display device, and the display device is convenient to realize software.
Furthermore, the display method of the present invention may also upload a file record of the display device to the server, the display device generates an upload two-dimensional code, the user scans the upload two-dimensional code through the mobile terminal to identify a unique upload session code, the display device sends the unique upload session code to the server, and generates a unique upload record ID corresponding to the unique upload session code on the server, the display device requests the server to return the unique upload record ID corresponding to the unique upload session code through the unique upload session code, and sends the upload record and the unique upload record ID together to the server for storage, so as to generate a download record of the server.
Further, the display method of the present invention also associates the download (upload) records with the users, so that the download (upload) records of different users can be managed to protect the file privacy of different users.
In addition, the display method only needs the display equipment and the mobile terminal to be capable of normally accessing the Internet in network communication, and operation of a user is facilitated.

s31: the display equipment generates an uploading record;
in step S31, the display device saves the data drawn thereon, and saves the drawn data for each page as one picture, respectively, thereby generating an upload record.
S32: the display equipment generates an uploading two-dimensional code corresponding to the uploading record, wherein the uploading two-dimensional code comprises a unique uploading session code;
specifically, step S32 includes the following sub-steps:
s321: the display device requests the server to upload a session code;
the method for the display device to request the server to upload the session code is the same as the method for the display device to request the server to download the session code.
S322: the display equipment receives the unique uploading session code returned by the server;
the server receives a data packet which is sent by the display equipment and requests to upload the session code, generates the upload session code and stores the upload session code in a table of a database of the server. The upload session code has uniqueness and is generated in the same manner as the download session code, and the generation of the upload session code may be performed by adding a random number to a timestamp or by extending the timestamp. The uniqueness of the uploading session code can be ensured because the timestamp for generating the uploading session code has uniqueness. The uniqueness of the upload session code can ensure that different upload records can be distinguished.
S323: and the display equipment generates the corresponding uploading two-dimensional code according to the unique uploading session code.
Wherein, the data content of the uploading two-dimensional code comprises the unique uploading session code.
