In an embodiment, as shown in fig. 2, a file screen sharing method is provided, and the file screen sharing system in fig. 1 is used as an example for explaining the method, which includes the following steps:
s201: generating a file sharing instruction corresponding to the target file ID by the sharing mobile phone end, and sending the file sharing instruction to the cloud system;
s202: the cloud system responds to the file sharing instruction, generates a file sharing URL corresponding to the target file ID, and sends the file sharing URL to the sharing mobile phone terminal;
s203: the sharing mobile phone end sends the file sharing URL to the screen throwing end;
s204: the screen throwing end generates a file sharing two-dimensional code corresponding to the file sharing URL according to the file sharing URL, and displays the file sharing two-dimensional code;
s205: the method comprises the steps that a mobile phone terminal is involved in scanning a file sharing two-dimensional code, a file downloading instruction corresponding to a file sharing URL is generated, and the file downloading instruction is sent to a cloud system;
s206: the cloud system receives the file downloading instruction, analyzes the file downloading instruction, acquires the target file, and sends the target file to the participating mobile phone terminal.
Wherein the target file ID is an identification for uniquely identifying a certain target file. The target file refers to a file which needs to be shared in a screen throwing way at the time. The file sharing instruction is an instruction triggered by the sharing mobile phone end and used for realizing file sharing.
As an example, in step S201, the sharing mobile phone end may select a specific conference file or teaching file in the mobile phone screen-throwing application, and determine the specific conference file or teaching file as the target file; and clicking a file sharing button of the mobile phone screen-throwing application by a user, generating a file sharing instruction corresponding to the target file ID, and sending the file sharing instruction to the cloud system, namely sending the file sharing instruction to the cloud system through a mobile phone connection module of the sharing mobile phone end and a cloud pushing module of the cloud system, so that the cloud system executes subsequent file screen-throwing sharing operation.
The file sharing URL is used for determining a path or other related information of the target file in the cloud system.
As an example, in step S202, the cloud system analyzes a file sharing instruction sent by a sharing mobile phone end when receiving the file sharing instruction, and determines a target file ID corresponding to the file sharing instruction; then, a file sharing URL corresponding to the target file ID is generated so that the target file can be found by using the file sharing URL later.
In this example, after analyzing the file sharing instruction and determining the target file ID corresponding to the file sharing instruction, the cloud system may query the cloud database based on the target file ID to determine whether the cloud database stores the target file; if the cloud database stores the target file, generating a file sharing URL corresponding to the ID of the target file; if the cloud database does not store the target file, generating file non-uploading information, and sending the file non-uploading information to the sharing mobile phone terminal. When the sharing mobile phone terminal receives information that the file is not uploaded, the target file needs to be uploaded to the cloud system. The cloud system receives the target file, generates file record information corresponding to the target file, and sends the file record information to the sharing mobile phone terminal.
The file record information is information for recording that the target file is stored in the cloud database. As an example, the file record information includes, but is not limited to, information such as a target file name, a target file size, a target file ID, a target file path, and a target file owner, which correspond to the target file. The target file name refers to the name of the target file. The target file ID is an ID for uniquely identifying a certain target file. The target file path refers to a path in which the target file is stored in the cloud database. The target file owner refers to the owner of the target file, namely a sharing user who operates the sharing mobile phone terminal to upload the target file.
In step S203, after receiving the file sharing URL sent by the cloud system, the sharing mobile phone end may determine the device ID and the device MAC corresponding to the screen-throwing end, and send the file sharing URL to the corresponding screen-throwing end through the point-to-point connection established between the sharing mobile phone end and the screen-throwing end, so that the screen-throwing end may share the file sharing URL.
In step S204, the screen-throwing end may receive the file sharing URL transmitted by the sharing mobile phone end through the peer-to-peer connection, and may use a two-dimension code generating tool to encode the file sharing URL, so as to generate the file sharing two-dimension code corresponding to the file sharing URL. The screen-throwing end displays the file sharing two-dimension code, so that a participating user can scan the file sharing two-dimension code displayed by the screen-throwing end by utilizing the code scanning application in the participating mobile phone end, and the subsequent file sharing operation is completed.
The file downloading instruction is an instruction which is triggered by the mobile phone terminal and is used for achieving the purpose of downloading the file.
As an example, step S205, the code scanning application in the mobile phone end scans the file sharing two-dimensional code displayed on the screen-throwing end to obtain the file sharing URL corresponding to the file sharing two-dimensional code; analyzing the file sharing URL to obtain information such as a downloaded website, a target random number and the like corresponding to the mobile phone screen-throwing application; then, generating a file downloading instruction corresponding to the file sharing URL according to the downloading website and the target random number corresponding to the mobile phone screen-throwing application; then, the participating mobile phone end can send the file downloading instruction to the cloud system.
As an example, in step S206, the cloud system receives a file downloading instruction sent by a participating mobile phone, parses the file downloading instruction, and determines a target random number in the file downloading instruction; then, inquiring a cloud database according to the target random number to obtain a target file ID corresponding to the target random number; and then inquiring a cloud database according to the target file ID, acquiring a target file, and sending the target file to the participating mobile phone end, so that the participating mobile phone end can receive the target file, and the purpose of sharing the files by projecting the screen is achieved.
In the file screen sharing method provided by the embodiment, the sharing mobile phone end sends the generated file sharing instruction to the cloud system, and sends the file sharing URL returned by the cloud system to the screen end, so that the screen end displays the file sharing two-dimensional code corresponding to the file sharing URL; the participating mobile phone terminal scans the file sharing two-dimensional code, and sends a file downloading instruction to the cloud system to receive the target file sent by the cloud system, so that the file screen-throwing sharing operation process is simple, and the operation convenience of the file screen-throwing sharing operation process is guaranteed.
In an embodiment, as shown in fig. 3, step S202, that is, the cloud system responds to the file sharing instruction to generate a file sharing URL corresponding to the target file ID, and sends the file sharing URL to the sharing mobile phone, includes:
s301: the cloud system analyzes the file sharing instruction and generates a target random number corresponding to the target file ID;
s302: the cloud system determines the target file ID and the target random number as target sharing information, and stores the target sharing information in a cloud database in an associated manner;
s303: the cloud system generates a file sharing URL corresponding to the target file ID based on the downloaded website and the target random number corresponding to the mobile phone screen-throwing application, and sends the file sharing URL to the sharing mobile phone terminal.
The target random number refers to a random number which is generated at the current moment of the system and is associated with the target file ID.
As an example, in step S301, the cloud system parses a file sharing instruction to obtain a target file ID in the file sharing instruction; when the cloud database stores the target file, a random number generation script can be adopted to generate a target random number corresponding to the target file. For example, the cloud system may generate a random number with a length of 16 bytes as the target random number according to the received target file ID. Because the target random number has randomness, the safety verification is conveniently carried out by using the target random number later, and the safety of the screen-throwing sharing of the target file is ensured.
The target sharing information is used for recording information related to file screen sharing.
As an example, in step S302, after generating the target random number corresponding to the target file ID, the cloud system may use a Key-Value form to determine the target file ID and the target random number as target sharing information, and store the target sharing information in the cloud database for subsequent query operation.
The downloaded website corresponding to the mobile phone screen-throwing application refers to the official network address link of the mobile phone screen-throwing application.
In step S303, the cloud system may encapsulate the download website corresponding to the mobile phone screen application stored in advance in the system and the target random number generated at the current time of the system in URL format to form a file sharing URL, so that the file sharing URL includes information such as the download website corresponding to the mobile phone screen application and the target random number, so that the participating mobile phone terminal may obtain the target file according to the file sharing URL, and complete the file screen sharing operation.
Understandably, the file sharing URL includes a download website and a target random number corresponding to the mobile phone screen-throwing application, and the target random number is associated with the target file ID for storage, so that the participating mobile phone terminal can obtain the target file according to the file sharing URL, directly according to the target file ID corresponding to the target random number, or firstly according to the download website corresponding to the mobile phone screen-throwing application, and then according to the target file ID corresponding to the target random number, obtain the target file, so as to ensure feasibility and safety of the file screen-throwing sharing operation.
In an embodiment, after step S301, that is, after the cloud system determines the target file ID and the target random number as the target sharing information, the target sharing information is stored in the cloud database in an associated manner, the file screen-projection sharing method further includes: the cloud system determines the validity period of the random number corresponding to the target random number.
As an example, after generating the target random number corresponding to the target file ID, the cloud system may determine the validity period of the random number corresponding to the target random number according to the current time of the system and a preset validity period. For example, when the current time of the system is T1 and the validity period is T, the validity period of the random number corresponding to the target random number is a period from T1 to t1+t. Understandably, after the cloud system generates the target random number, the random number validity period corresponding to the target random number needs to be recorded so as to perform security verification based on the random number validity period, so as to ensure timeliness of the target random number, and further help to ensure security of file screen sharing operation.
In an embodiment, as shown in fig. 4, step S205, that is, the participating mobile phone end scans the file sharing two-dimensional code, generates a file downloading instruction corresponding to the file sharing URL, and sends the file downloading instruction to the cloud system, includes:
s401: the participating mobile phone end scans the file sharing two-dimensional code by adopting a code scanning application to obtain a file sharing URL;
s402: the participating mobile phone terminal analyzes the file sharing URL to obtain target sharing information, wherein the target sharing information comprises target random numbers;
s403: the participating mobile phone terminal generates a file downloading instruction based on the target random number, and sends the file downloading instruction to the cloud system.
In step S401, the participating mobile phone end may use a code scanning application, including but not limited to a mobile phone screen-throwing application, a system camera, a WeChat or other applications with code scanning function, to scan the file sharing two-dimensional code displayed on the screen-throwing end to identify the file sharing URL in the file sharing two-dimensional code.
As an example, in step S402, the participating mobile phone end adopts an parsing tool corresponding to the URL format to parse the file sharing URL to obtain target sharing information corresponding to the file sharing URL, where the target sharing information includes a target random number, and the target random number is a random number formed by the cloud system based on the file sharing instruction sent by the sharing mobile phone end.
As an example, in step S403, the participating mobile phone end may generate a file downloading instruction related to the target random number based on the parsed target random number, and send the file downloading instruction to the cloud system, so that the cloud system may obtain the target file related to the target random number according to the file downloading instruction, and send the target file to the participating mobile phone end, so that the participating mobile phone end may obtain the target file shared by the sharing mobile phone end conveniently, and the file screen-throwing sharing operation is completed.
In an embodiment, the target sharing information further includes a download website corresponding to the mobile phone screen-throwing application;
step S403, namely, generating a file downloading instruction by the participating mobile phone terminal based on the target random number, and sending the file downloading instruction to the cloud system, including:
s4031: when the code scanning application is a mobile phone screen projection application, the participating mobile phone terminal generates a file downloading instruction based on the target random number, and sends the file downloading instruction to the cloud system;
s4032: when the code scanning application is not the mobile phone screen projection application, the participating mobile phone terminal downloads and installs the mobile phone screen projection application based on the download website, jumps to the mobile phone screen projection application, generates a file downloading instruction based on the target random number, and sends the file downloading instruction to the cloud system.
As an example, in step S402, the participating mobile phone end parses the file sharing URL, and the obtained target sharing information includes not only the target random number but also the download website corresponding to the mobile phone screen-throwing application. Correspondingly, in step S403, the participating mobile phone terminal generates a file downloading instruction based on the target random number, and sends the file downloading instruction to the cloud system, which specifically includes the following two cases:
in the first case, when the code scanning application of the two-dimension code sharing of the mobile phone terminal is the mobile phone screen-throwing application, the corresponding file downloading instruction can be generated directly based on the target random number, and the file downloading instruction is sent to the cloud system, so that the cloud system sends the target file to the mobile phone screen-throwing application of the mobile phone terminal, and the file screen-throwing sharing function is completed through the mobile phone screen-throwing application.
