[0025] Exhibition hall design is a type of exhibition design. Exhibition is defined as an activity that uses the optimal spatial relationship between objects, people, and space to convey specific information. In exhibition hall design, playing information through multimedia equipment can better showcase a company's image and create a refreshing visual effect. Currently, when playing information, multimedia equipment in exhibition halls requires storing pre-made information files on a flash drive on the device's hard drive. The device then reads and plays the information. However, flash drives may carry viruses, posing a security risk when copying multimedia files to the device.

[0026] The acquisition, storage, use, and processing of data in this application all comply with the relevant provisions of national laws and regulations.

[0027] To address the problems of the prior art, embodiments of this application provide a method, apparatus, device, storage medium, and program product for sending multimedia files in an exhibition hall. The method for sending multimedia files in an exhibition hall provided in this application embodiment will be described first below.

[0028] Figure 1 A flowchart illustrating a method for sending multimedia files in an exhibition hall according to an embodiment of this application is shown. Figure 1 As shown, a method for sending multimedia files in an exhibition hall, applied to a server, may include the following steps S101 to S104:

[0029] S101. When the server is connected to the management terminal and at least one playback terminal, if a first request is received, a notification message corresponding to the first request is generated. The first request is used to request the playback of a multimedia file on at least one playback terminal.

[0030] S102, Send a notification message to at least one playback terminal;

[0031] S103. Upon receiving a second request from at least one playback terminal in response to a notification message, perform security authentication on the second request sent by at least one playback terminal to obtain a first authentication result corresponding to each playback terminal. The first authentication result is used to indicate whether the second request sent by the corresponding playback terminal is secure.

[0032] S104. If the first authentication result corresponding to the target playback terminal indicates that the second request is secure, transmit the multimedia file corresponding to the first request to the target playback terminal so that the target playback terminal can play the multimedia file corresponding to the first request.

[0033] The method for sending multimedia files in an exhibition hall according to this application embodiment is applied to a server. When the server is communicatively connected to a management terminal and at least one playback terminal, if a first request is received, a notification message corresponding to the first request is generated. The first request requests that a multimedia file be played on at least one playback terminal, and the notification message is sent to at least one playback terminal. Upon receiving a second request from at least one playback terminal in response to the notification message, security authentication is performed on the second request sent by the at least one playback terminal, obtaining a first authentication result corresponding to each playback terminal. If the first authentication result corresponding to the target playback terminal indicates that the second request is secure, the multimedia file corresponding to the first request is transmitted to the target playback terminal, enabling the target playback terminal to play the multimedia file corresponding to the first request. Thus, this embodiment can perform security authentication on the second request sent by the playback terminal to ensure the security of the playback terminal, thereby achieving secure transmission of multimedia files to the corresponding playback terminal.

[0034] In S101, the aforementioned server can be a server that receives, stores, and sends multimedia files in the exhibition hall, and is responsible for data processing between the middle layer and the back-end layer in the exhibition hall system.

[0035] The aforementioned management terminal can be the terminal through which an administrator user sends the first request to the server. Furthermore, the management terminal can also perform CRUD operations on multimedia files, or on at least one playback terminal, as well as on the playback schedule information.

[0036] The aforementioned playback terminal can be a terminal used to play multimedia files. In this embodiment, it can be a playback display screen in an exhibition hall.

[0037] The communication connection between the server and the management terminal and at least one playback terminal can be, for example, via wireless communication methods such as Bluetooth or Wi-Fi, or via wired communication methods using tangible media such as metal wires or optical fibers.

[0038] The aforementioned first request can be used to request the playback of a multimedia file on at least one playback terminal, or it can also request at least one playback terminal to play a multimedia file based on playback plan information.

[0039] In some embodiments, in S101 above, if a first request is received, a notification message corresponding to the first request is generated, which may specifically include:

[0040] If a first request is received, the first request is authenticated to obtain a second authentication result. The second authentication result is used to indicate whether the first request sent by the management terminal is secure.

[0041] If the second authentication result indicates that the first request sent by the management terminal is secure, a notification message corresponding to the first request is generated.

[0042] For example, the security authentication of the first request can be performed by the server decrypting the token message in the first request into a JSON Web Token (JWT) and verifying whether it matches the configuration information of the preset management terminal in the server.

[0043] The aforementioned second authentication result can be used to indicate whether the first request sent by the management terminal is secure. For example, if the information of the token message in the first request after being decrypted by JWT matches the preset configuration information, it is determined that the second authentication result indicates that the first request sent by the management terminal is secure; otherwise, it is insecure.

[0044] In this embodiment, by performing security authentication on the first request and generating a notification message corresponding to the first request only when the second authentication result indicates that the first request sent by the management terminal is secure, the security of information interaction between the management terminal and the server can be improved.

[0045] In S102, the aforementioned notification message, which corresponds to the first request, is sent by the server to at least one playback terminal to notify each playback terminal to send a second request to the server.

[0046] In S103, the aforementioned security authentication of the second request sent by at least one playback terminal can, for example, involve the server performing JWT decryption on the token message in the second request and verifying whether it matches the configuration information of at least one playback terminal preset in the server.

[0047] The first authentication result can be used to indicate whether the second request sent by the corresponding playback terminal is secure. For example, if the information of the token message after JWT decryption in the second request matches the preset configuration information, it is determined that the first authentication result and the second request sent by the corresponding playback terminal are secure; otherwise, it is insecure.

[0048] In S104, the target playback terminal can be at least one playback terminal in which the first authentication result indicates the second requesting security playback terminal.

[0049] The aforementioned transmission of the multimedia file corresponding to the first request to the target playback terminal can enable the target playback terminal to play the multimedia file corresponding to the first request, or enable the target playback terminal to play multiple multimedia files corresponding to the first request according to the playback plan information.

[0050] In some embodiments, the notification message may include playback plan information, which may be used to instruct the playback terminal to play a plan of multiple multimedia files.

[0051] Specifically, S104 mentioned above may include:

[0052] If the first authentication result corresponding to the target playback terminal indicates that the second request is secure, multiple multimedia files corresponding to the first request are transmitted to the target playback terminal so that the target playback terminal can play the multiple multimedia files corresponding to the first request according to the playback plan information.

[0053] The aforementioned playback plan information can be used to instruct the playback terminal on a plan for playing multiple multimedia files. For example, it can instruct the playback terminal on a playback order plan or a playback time plan for playing multiple multimedia files.

[0054] In this embodiment, when the first authentication result corresponding to the target playback terminal indicates that the second request is secure, transmitting multiple multimedia files corresponding to the first request to the target playback terminal enables the target playback terminal to play the multiple multimedia files corresponding to the first request according to the playback plan information, thereby satisfying the user's need for planned playback of multiple multimedia files.

[0055] As one implementation of this application, in order to meet the requirement of different playback terminals in the exhibition hall playing different multimedia files, the aforementioned server is communicatively connected to the management terminal and multiple playback terminals; before transmitting the multimedia file corresponding to the first request to the target playback terminal, it may further include:

[0056] In response to the first request, playback relationship information associated with multiple playback terminals is generated. The playback relationship information is used to indicate multiple playback relationships, and the multiple playback relationships correspond to multiple playback terminals. Each playback relationship is the relationship between its corresponding playback terminal and at least one multimedia file, and at least one multimedia file corresponds to the first request.

[0057] The aforementioned transmission of the multimedia file corresponding to the first request to the target playback terminal may specifically include:

[0058] Based on the playback relationship information, the corresponding target playback relationship is determined. The target playback relationship is the playback relationship that corresponds to the target playback terminal among multiple playback relationships.

[0059] Transmit at least one target multimedia file to the target playback terminal, wherein each target multimedia file is a multimedia file in the target playback relationship.

[0060] The aforementioned playback relationship information can be used to indicate multiple playback relationships, wherein the multiple playback relationships correspond to multiple playback terminals, and each playback relationship is the relationship between its corresponding playback terminal and at least one multimedia file, and at least one multimedia file corresponds to the first request.

[0061] The above-mentioned response to the first request to generate playback relationship information associated with multiple playback terminals may include responding to the first request and generating playback relationship information associated with multiple playback terminals according to relationship indication information, wherein the first request includes relationship indication information, which is used to instruct each playback terminal to change the relationship between itself and the multimedia files corresponding to the playback terminal.

[0062] In this embodiment, based on the playback relationship information, the corresponding target playback relationship is determined, and at least one target multimedia file is transmitted to the target playback terminal. This enables each target terminal to play the multimedia file corresponding to the playback relationship, thereby fulfilling the requirement for different playback terminals in the exhibition hall to play different multimedia files.

[0063] In some embodiments, the first request includes relationship indication information, which is used to instruct each playback terminal to change the relationship between the multimedia files corresponding to the playback terminal;

[0064] In response to the first request, the above-mentioned method generates playback relationship information associated with multiple playback terminals, which may specifically include:

[0065] In response to the first request, playback relationship information associated with multiple playback terminals is generated based on the relationship indication information.

[0066] The aforementioned relationship indication information can be used to instruct each playback terminal to change the relationship between itself and the multimedia files corresponding to the playback terminal. For example, it can be used to instruct the first playback terminal to change the first multimedia file it is playing to the second multimedia file among multiple playback terminals.

[0067] In this embodiment, playback relationship information associated with multiple playback terminals is generated based on the relationship indication information in the first request, so as to enable each playback terminal to change the multimedia file corresponding to the playback terminal, thereby improving the flexibility of playing multimedia files in the exhibition hall.

[0068] As another implementation of this application, in order to improve the security of multimedia file transmission in the exhibition hall, before the above-mentioned S101, it may also include:

[0069] Obtain the device code of at least one playback terminal, where the device code is a unique identifier for the playback terminal;

[0070] Security authentication is performed on the device code of each playback terminal to obtain a third authentication result corresponding to each playback terminal. The third authentication result is used to indicate whether the playback terminal corresponding to it is secure.

[0071] Specifically, S101 mentioned above may include:

[0072] When the server is connected to the management terminal and at least one playback terminal, and at least one third authentication result indicates that the playback terminal is secure, if a first request is received, a notification message corresponding to the first request is generated.

[0073] The aforementioned device code can serve as a unique identifier for the playback terminal. In addition, the management terminal also has a unique device code.

[0074] The aforementioned security authentication of the device codes of each playback terminal to obtain a third authentication result corresponding to each playback terminal may include security authentication of the device codes of the management terminal and each playback terminal to obtain a third authentication result corresponding to the management terminal and each playback terminal.

[0075] The aforementioned security authentication can involve the server encrypting the device code of each playback terminal according to a preset encryption rule, obtaining various encryption results, and comparing each encryption result with the preset configuration information of each playback terminal in the server. If the comparison matches, it indicates that the third authentication result indicates the playback terminal is secure; otherwise, if the comparison does not match, it indicates that the third authentication result indicates the playback terminal is insecure.

[0076] In this embodiment, before the server generates a notification message corresponding to the first request if it receives the first request, security authentication is performed on the device encoding of each playback terminal to improve the security of sending multimedia files in the exhibition hall.

[0077] To facilitate understanding of the method for sending multimedia files in the exhibition hall according to the embodiments of this application, the actual application process of this method for sending multimedia files in the exhibition hall is described as follows:

[0078] like Figure 2 As shown, this embodiment provides an application scenario for a method of sending multimedia files in an exhibition hall:

[0079] When the management client (i.e., the aforementioned management terminal) and the playback client (i.e., the aforementioned playback terminal) are connected to the server (including the middle layer and the back-end layer, where the middle layer includes the message center and the security center, and the back-end layer includes the storage center and the management center), the management client sends a business request (i.e., the aforementioned first request) to the server's security center. The security center performs security authentication, and after successful authentication, it allows the business request to be processed by the management center in the server's back-end layer. The management center processes the business according to the business request, saves the relevant multimedia files to the storage center, and publishes the playback plan information to the message center. The playback client subscribes to the relevant services of the message center. When the management center updates the message queue, the playback client receives the message content from the message center. Based on the received message content, the playback client sends a download resource request (i.e., the aforementioned second request) to the security center. After successful authentication, the security center allows the download resource request to be processed by the storage center. After the playback client downloads the display resources (i.e., multimedia files) to its local machine, it can implement the playback function according to the playback plan.

[0080] The functional units described above will be introduced in detail below.

[0081] I. Playback Client

[0082] The playback client is implemented using Python and its plugins, which can send HTTP requests to interact with the security center, register, log in, and request to download resources.

[0083] Configure the message center address and JASS attributes in the playback client, and write the code for the consumer (referring to the playback client) and listener (referring to the management client). This process mainly uses the API calls of its plugins, so that it can connect to the message center (implemented by Kafka) and implement the subscription-publish function, so that it can obtain information pushed to the message center from the management center in real time.

[0084] Business processes involved:

[0085] The playback client obtains and encapsulates the device registration information (the registration information mainly includes: device number, registration code, fingerprint information, and MAC address), and registers it by sending an HTTP request to the security center.

[0086] The playback client obtains and encapsulates the login information (which mainly includes: device number, fingerprint information, and MAC address), and logs in by sending an HTTP request to the security center.

[0087] The playback client subscribes to the playback service of the message center (using Python and its plugins). The message center is implemented using Kafka. SASL authentication is enabled in the Kafka server configuration file. The JAAS attribute is configured in the playback client. This enables the authentication function between the playback client and the message center. Once authentication is successful, the playback client can obtain playback service information from the message center.

[0088] Based on the obtained playback service information, the playback client sends an HTTP request to the security center to download the resource. After the request is successful, the downloaded resource is loaded and played according to the playback plan.

[0089] II. Management Client

[0090] The management client is a front-end system for a management platform implemented based on elementUI and vue.js. It provides visual operations for various interfaces, allowing users to interact with the management center by manipulating the components of the management client to modify data.

[0091] Responsible for adding, deleting, modifying, and querying data on the playback client;

[0092] Adding, deleting, modifying, and querying multimedia file resources;

[0093] Responsible for adding, deleting, modifying, and querying playback schedules;

[0094] The management client needs to log in to access the platform and manipulate data. After logging in, it interacts with the security center and receives a token. Subsequent service requests sent to the security center will include this token.

[0095] The relevant business process is completed by sending an AJAX request from a Vue.js component to the management center via the security center.

[0096] III. Security Center

[0097] The security center is implemented based on Spring Boot, Spring Security, and JWT.

[0098] Its basic principle is to use the Spring Security framework to load the configured permission authentication rules and encrypt user information during initialization;

[0099] After the service has started, a successful login request will encrypt the login information into a token using JWT and return it to the corresponding management client or playback client.

[0100] The management client sends a business request with token information to the security center. The token information is decrypted using JWT, and the token information is verified according to the configuration information. If the authentication is successful, the request is allowed to be sent to the management center or storage center; otherwise, it is blocked.

[0101] IV. Message Center

[0102] The message center is a queue service built using Kafka. By enabling SASL authentication in the Kafka configuration file, the message queue can be transmitted using the publish-subscribe pattern (here, the playback client uses relevant components to subscribe to a service of a topic, and when the management center publishes a queue to the service of that topic, the playback client will receive the information in real time).

[0103] After successful configuration, the management center can use Java and its components to push queue information to the message center. After receiving the queue information, the message center will push the information to the subscribed playback clients (implemented in Python and its components, with the connection attributes of the message center configured and the listener and consumer code written).

[0104] V. Management Center

[0105] The management center is a Java-based backend service (Spring Boot + MyBatis). Requests passed through the security center are processed for business logic. This scenario involves modifying the MySQL database, which is achieved by Java calling the MyBatis framework's API to operate the database. For push messaging, the Kafka-client component is used to push information to the message center. Specifically, this involves configuring the message center service connection properties (Kafka connection configuration properties, enabling client JASS properties for Kafka security authentication). After configuration, producer code is written, primarily using the APIs in the Kafka-client component to pass messages to the functional methods according to API rules, thus implementing the message center push functionality. For file storage, the FastDFS component is used to operate on FastDFS for file storage. This is implemented by first configuring the FastDFS service address and saving the path prefix, then writing file upload code using the APIs provided by FastDFS-Java to upload files to the FastDFS server.

[0106] VI. Storage Center

[0107] A distributed file system implemented using FastDFS.

[0108] The FastDFS architecture includes a Tracker server and a Storage server.

[0109] Its functional implementation process:

[0110] The client requests the Tracker server to upload and download files; the Tracker server then schedules the storage server to ultimately complete the file upload and download.

[0111] In this embodiment, security authentication ensures the security of the entire system, the publish-subscribe model ensures timeliness, and operations can be performed only on the management client, making it convenient to operate.

[0112] Based on the method for sending multimedia files in an exhibition hall provided in the above embodiments, this application also provides a specific implementation of a device for sending multimedia files in an exhibition hall. Please refer to the following embodiments.

[0113] like Figure 3 As shown in the embodiment of this application, the multimedia file sending device 300 for exhibition halls is applied to a server and may include the following modules: a first generation module 301, a first sending module 302, a first security authentication module 303, and a second sending module 304.

[0114] The first generation module 301 is used to generate a notification message corresponding to the first request if a first request is received when the server is in communication connection with the management terminal and at least one playback terminal. The first request is used to request the playback of a multimedia file on at least one playback terminal.

[0115] The first sending module 302 is used to send a notification message to at least one playback terminal;

[0116] The first security authentication module 303 is used to perform security authentication on the second request sent by at least one playback terminal in response to the notification message when receiving a second request from at least one playback terminal in response to the second request sent by the notification message, and to obtain a first authentication result corresponding to each playback terminal. The first authentication result is used to indicate whether the second request sent by the corresponding playback terminal is secure.

[0117] The second sending module 304 is used to transmit a multimedia file corresponding to the first request to the target playback terminal when the first authentication result corresponding to the target playback terminal indicates that the second request is secure, so that the target playback terminal can play the multimedia file corresponding to the first request.

[0118] The multimedia file sending device for an exhibition hall according to this application embodiment is applied to a server. When the server is communicatively connected to a management terminal and at least one playback terminal, if a first request is received, a notification message corresponding to the first request is generated. The first request requests the playback of a multimedia file on at least one playback terminal, and the notification message is sent to the at least one playback terminal. Upon receiving a second request from at least one playback terminal in response to the notification message, security authentication is performed on the second request sent by the at least one playback terminal, obtaining a first authentication result corresponding to each playback terminal. If the first authentication result corresponding to the target playback terminal indicates that the second request is secure, the multimedia file corresponding to the first request is transmitted to the target playback terminal, enabling the target playback terminal to play the multimedia file corresponding to the first request. Thus, this embodiment can perform security authentication on the second request sent by the playback terminal to ensure the security of the playback terminal, thereby achieving secure transmission of multimedia files to the corresponding playback terminal.

[0119] As one implementation of this application, in order to meet the requirement of different playback terminals in the exhibition hall playing different multimedia files, the aforementioned server is connected to the management terminal and multiple playback terminals.

[0120] The aforementioned device 300 may further include:

[0121] The second generation module is used to respond to the first request and generate playback relationship information associated with multiple playback terminals. The playback relationship information is used to indicate multiple playback relationships, and the multiple playback relationships correspond to multiple playback terminals. Each playback relationship is the relationship between its corresponding playback terminal and at least one multimedia file, and at least one multimedia file corresponds to the first request.

[0122] The aforementioned second transmitting module 304 may specifically include:

[0123] The determining unit is used to determine the corresponding target playback relationship based on the playback relationship information. The target playback relationship is the playback relationship that corresponds to the target playback terminal among multiple playback relationships.

[0124] The sending unit is used to transmit at least one target multimedia file to the target playback terminal, wherein each target multimedia file is a multimedia file in the target playback relationship.

[0125] In some embodiments, the first request includes relationship indication information, which is used to instruct each playback terminal to change the relationship between the multimedia files corresponding to the playback terminal;

[0126] The second generation module is specifically used to respond to the first request and generate playback relationship information associated with multiple playback terminals based on the relationship indication information.

[0127] In some embodiments, the first generation module 301 may specifically include:

[0128] The security authentication unit is used to perform security authentication on the first request if it receives the first request, and obtain a second authentication result. The second authentication result is used to indicate whether the first request sent by the management client is secure.

[0129] The generation unit is used to generate a notification message corresponding to the first request if the second authentication result indicates that the first request sent by the management client is secure.

[0130] In some embodiments, the notification message includes playback plan information, which is used to instruct the playback terminal to play a plan for multiple multimedia files.

[0131] The aforementioned second sending module 304 can be specifically used to transmit multiple multimedia files corresponding to the first request to the target playback terminal when the first authentication result corresponding to the target playback terminal indicates that the second request is secure, so that the target playback terminal can play the multiple multimedia files corresponding to the first request according to the playback plan information.
