[0024] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] See also Figure 1 The structure diagram of an online course recording and broadcasting system is shown. This embodiment proposes an online course recording and broadcasting system, including: an online classroom platform 100, an all-in-one card management system 102 and a recording and broadcasting platform 104.

[0027] The one-card management system is used to store user information and class schedule information.

[0028] The online classroom platform is used to send a first information call request to the one-card management system, receive and store user information and class schedule information fed back by the one-card management system; when receiving a second information call request sent by the recording and broadcasting platform, it sends the user information and class schedule information to the recording and broadcasting platform, and receives the recorded and broadcasting class schedule generated by the recording and broadcasting platform for users of online courses to watch on demand.

[0029] The recording and broadcasting platform is used to send the second information call request to the online classroom platform, receive the user information and the class schedule information sent by the online classroom platform; obtain the recording and broadcasting class schedule of the user indicated by the user information based on the user information and the class schedule information; record the online course in real time based on the class schedule information to obtain the on-demand video of the online course, associate the obtained on-demand video of the online course with the matching user's recorded and broadcasting class schedule, and send the recorded and broadcasting class schedule associated with the on-demand video of the online course to the online classroom platform.

[0030] Among them, the one-card system is designed as a monolithic architecture and provides a standard Restful API data interface to the outside world, so that the online classroom platform can obtain the user information and course information stored in the one-card system through the data interface provided by the one-card system.

[0031] The online classroom platform, based on a microservices architecture, provides standard interface documentation for each service, along with detailed user guides, to facilitate future platform maintenance and upgrades, the development and expansion of functional modules, the integration of multiple clients, and the integration of third-party platforms. Users can log in to the online classroom platform to watch live and recorded online courses on-demand.

[0032] In one embodiment, the user information includes: a user ID and a class ID; the course schedule information includes: a class ID, an online course ID, and an online course teaching time.

[0033] Specifically, the online classroom platform is used to send a first information call request to the one-card management system, receive and store user information and class schedule information fed back by the one-card management system, including the following steps (1) to (3):

[0034] (1) sending a first information call request to the one-card management system, so that the one-card management system feeds back user information and class schedule information to the online classroom platform;

[0035] (2) receiving user information and class schedule information sent by the card management system;

[0036] (3) Put the received user information and course schedule information into the RabbitMQ message queue, perform uniqueness verification on the user information and course schedule information one by one, and store the user information and course schedule information that pass the uniqueness verification.

[0037] In the above step (3), the user identifier in the user information is used to traverse the remaining user information. If the user identifier cannot be obtained by traversing the remaining user information, it is determined that the user information with the traversed user identifier has passed the uniqueness verification.

[0038] The class ID in the timetable information is used to traverse the remaining timetable information. When the class ID cannot be obtained by traversing the remaining timetable information, it is determined that the timetable information with the traversed class ID has passed the uniqueness verification.

[0039] Specifically, the online classroom platform is configured to send the user information and the course schedule information to the recording and broadcasting platform upon receiving the second information call request sent by the recording and broadcasting platform, including the following steps (11) to (17):

[0040] (11) upon receiving a second information call request sent by the recording and broadcasting platform, obtaining stored user information and course schedule information;

[0041] (12) determining the initial letter of the user ID and the initial letter of the class ID in the user information, and the initial letter of the class ID, the initial letter of the online course ID, and the initial letter of the online course teaching time in the course schedule information;

[0042] (13) Sort the user IDs and class IDs in the user information according to the alphabetical order of the first letters of the user IDs and the first letters of the class IDs, and sort the class IDs, online course IDs, and online course teaching times in the course schedule information according to the alphabetical order of the first letters of the class IDs, the first letters of the online course IDs, and the first letters of the online course teaching times;

[0043] (14) Concatenating the sorted user ID and class ID using a preset symbol to obtain a user information string, and encrypting the obtained user information string to obtain a first signature;

[0044] (15) The sorted class ID, online course ID, and online course teaching time are concatenated using a preset symbol to obtain a course schedule information string, and the obtained course schedule information string is encrypted to obtain a second signature;

[0045] (16) Using JWT to process user information to obtain a first token value, and using JWT to process course schedule information to obtain a second token value;

[0046] (17) Send the user information, class schedule information, first signature, second signature, first token value and second token value to the recording and broadcasting platform.

[0047] Correspondingly, the recording and broadcasting platform is used to send the second information call request to the online classroom platform, receive the user information and the course schedule information sent by the online classroom platform; and obtain the user's recording and broadcasting course schedule based on the user information and the course schedule information, including the following specific steps (20) to (23):

[0050] (22) Processing the course schedule information to obtain a fourth signature and a fourth token value. When the fourth signature is identical to the second signature and the fourth token value is identical to the second token value, storing the course schedule information;

[0051] (23) The class schedule information that carries the same class identifier as the user information is determined as the recorded class schedule of the user indicated by the user information, thereby obtaining the recorded class schedule of the user indicated by the user information.

[0052] In the above step (12), in one embodiment, if the user ID in the user information is xfg11212, the class ID is gaozhongnianji3banji2.

[0053] Then, the first letter of the user ID is x; the first letter of the class ID is g.

[0054] The method for determining the first letter of the class ID, the first letter of the online course ID, and the first letter of the online course teaching time in the course schedule information is similar to the method for determining the first letter of the user ID and the first letter of the class ID in the above-mentioned user information, and will not be repeated here.

[0055] In the above step (13), the order of the alphabetical sequence is: A, B, C, D...X, Y, Z.

[0056] Then, if the user ID in the user information is xfg11212 and the class ID is gaozhongnianji3banji2, the user information after sorting according to the order of the first letters in the English alphabet is gaozhongnianji3banji2 xfg11212.

[0057] The specific process of sorting the class ID, online course ID and online course teaching time in the course schedule information according to the alphabetical order of the first letter of the class ID, the first letter of the online course ID and the first letter of the online course teaching time is similar to the above-mentioned process of sorting the user ID and class ID in the user information according to the alphabetical order of the first letter of the user ID and the first letter of the class ID, and will not be repeated here.

[0058] In the above step (14), in one embodiment, the preset symbols may be “&” and “&&”.

[0059] When the preset symbol "&" is used, for the above-sorted user information gaozhongnianji3banji2xfg11212, the user ID and class ID in the sorted user information are concatenated using the preset symbol, and the resulting user information character string is: gaozhongnianji3banji2&xfg11212.

[0060] In one embodiment, any signature encryption algorithm in the prior art may be used to encrypt the obtained user information character string to obtain a first signature. The specific encryption process is a prior art and will not be described in detail here.

[0061] In the above step (15), the process of obtaining the second signature is similar to the process of obtaining the first signature in the above step (14), and will not be repeated here.

[0062] In the above step (16), the specific process of using JWT to process user information to obtain the first token value, and using JWT to process the course schedule information to obtain the second token value is existing technology and will not be repeated here.

[0063] In the above step (21), the specific process of the recording and broadcasting platform processing the user information to obtain the third signature and the third token value is similar to the specific process of the above online classroom platform processing the user information to obtain the first signature and the first token value, and will not be repeated here.

[0064] In the above step (22), the specific process of the recording and broadcasting platform processing the course schedule information to obtain the fourth signature and the fourth token value is similar to the specific process of the above online classroom platform processing the course schedule information to obtain the second signature and the second token value, and will not be repeated here.

[0065] In the above step (23), users may be, but are not limited to, students and teachers.

[0066] The recording and broadcasting platform is used to record the online course in real time according to the course schedule information, obtain the on-demand video of the online course, and associate the obtained on-demand video of the online course with the matching user's recording and broadcasting course schedule, including the following specific steps (1) to (6):

[0067] (1) determining the teaching time of the online course indicated by the online course identifier based on the online course identifier and the online course teaching time recorded in the course schedule information;

[0068] (2) when the current time reaches the teaching time of the online course indicated by the online course identifier, generating a live broadcast address of the online course indicated by the online course identifier, and generating a first correspondence between the live broadcast address of the online course indicated by the online course identifier and the class identifier, and feeding back the generated first correspondence to the online classroom platform, so that the online classroom platform displays the online course indicated by the online course identifier to the user indicated by the user information having the class identifier carried by the first correspondence for viewing;

[0069] (3) recording the online course indicated by the online course identifier in real time to obtain an on-demand video of the online course, storing the on-demand video of the online course, and obtaining a storage address of the on-demand video of the online course;

[0070] (4) determining the class identifier in the course schedule information where the online course identifier is located as the class identifier of the storage address of the on-demand video of the online course;

[0071] (5) determining from the recorded course schedule a class identifier that is identical to the class identifier of the storage address of the on-demand video of the online course;

[0072] (6) Associating the storage address of the on-demand video of the online course with the class identifier in the recorded class schedule that is the same as the class identifier of the storage address of the on-demand video of the online course, to obtain the recorded class schedule associated with the on-demand video of the online course.

[0073] In the above step (1), in one embodiment, the online course identifiers recorded in the course schedule information may be, but are not limited to: yuwenke212, shuxueke111, and yingyuke102.

[0074] The online course teaching time can be: 2022102208001000.

[0075] That is to say, the teaching time of the online course is: 8:00 to 10:00 on October 22, 2022.

[0076] In the above step (2), the current time is the system clock time of the recording and broadcasting platform.

[0077] By pulling traffic through live broadcast, an online course identifier can be generated to indicate the live broadcast address of the online course. The specific process is existing technology and will not be repeated here.

[0078] The generated online course identifier indicates that the live broadcast address of the online course carries the online course identifier.

[0079] In order to generate a first correspondence between the live broadcast address of the online course indicated by the online course identifier and the class identifier, the course schedule information with the online course identifier can be queried based on the online course identifier carried by the live broadcast address of the online course indicated by the online course identifier, and then the class identifier in the queried course schedule information is associated with the live broadcast address of the online course indicated by the online course identifier, so as to generate a first correspondence between the live broadcast address of the online course indicated by the online course identifier and the class identifier.

[0080] In summary, the online course recording and on-demand system proposed in this embodiment is an online course recording and on-demand system. In the online course recording and on-demand system, the online classroom platform can obtain user information and class schedule information from the one-card management system, and when obtaining the second information call request sent by the recording and broadcasting platform, it sends the user information and class schedule information to the recording and broadcasting platform.
