DETAILED DESCRIPTION

The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

The data output method provided by the embodiment of the present invention will be described in detail below with reference to Figures 1 to 4 .

Please refer to FIG. 1 , which is a flow chart of a data output method provided by an embodiment of the present invention; the method may include the following steps S100 to S102 .

S100, after a communication account is logged in to a client, receiving a media data acquisition request sent by the client, the acquisition request carrying the communication account;

In a specific embodiment, the client can be a media client, such as various music clients or video clients. After installing the client on various terminals, users can freely download various multimedia files, such as audio and video files, from the client using their communication accounts. To ensure that users can view the media data of previously downloaded multimedia files after logging into their communication accounts on various terminals, once the communication account is logged into the client, the client sends a media data acquisition request to the server, which carries the communication account. Optionally, the client can send the acquisition request to the server via a Common Gateway Interface (CGI), and the server can be a web server. As shown in FIG5 , the client sends the media data acquisition request to the web server. CGI is an interface standard between external applications and web servers, and is a procedure for transmitting information between external applications and web servers.

In the embodiment of the present invention, the media data may be the name, author, creation time, audio and video data of the multimedia file, etc. The client that the communication account logs into is not limited to the terminal platform. As long as the communication account logs into the client on the terminal platform, a media data acquisition request is sent to obtain historically downloaded media data.

S101, acquiring historical downloaded media data to be outputted and associated with the communication account according to the acquisition request;

In a specific embodiment, the server parses the communication account carried in the acquisition request sent by the client and obtains the historical downloaded media data associated with the communication account to be output. The historical downloaded media data associated with the communication account to be output is the media data of multimedia files historically downloaded by the communication account on various terminal platforms. The media data of the multimedia files can be attribute information of the multimedia files. For example, if the multimedia file is a song, the media data may include the song title, song album, and lyrics. As shown in Figure 4, the client displays the titles and artists of each song historically downloaded by the communication account.

In an embodiment of the present invention, the historical downloaded media data to be output can be the media data of all multimedia files in the download history associated with the account, or the media data of a portion of multimedia files in the download history associated with the communication account. For example, if the historical downloaded media data to be output is the media data of historically downloaded songs, the historical downloaded media data to be output can be the titles and artists of all songs downloaded by the communication account, or the titles and artists of a portion of songs downloaded by the communication account.

Optionally, if the client sends a media data acquisition request to the server via CGI, CGI retrieves the historical downloaded media data to be output associated with the communication account from the cloud distributed storage (Cloud Key Value, CKV). The historical downloaded media data may be encapsulated via an application layer protocol. When obtaining the historical downloaded media data to be output associated with the communication account, the historical downloaded media data encapsulated via the application layer protocol is decoded to obtain the specific media data for each historical download, and the requested historical downloaded media data to be output is then returned to the client.

S102: Return the historical downloaded media data to be output to the client for output.

In a specific embodiment, the server returns the acquired historical downloaded media data to be output to the client for output. The specific output method can be determined based on the existence form of the historical downloaded media data. For example, if the historical downloaded media data is attribute information of a multimedia file (song title and singer), the client displays the historical downloaded media data. If the historical downloaded media data is audio or video data of the multimedia file, the client plays the historical downloaded media data. In this way, the historical downloaded media data of multimedia files downloaded by the user on different terminal platforms associated with the communication account can be output, allowing the user to quickly learn the download history of the communication account and further operate the multimedia data in the download history, such as re-downloading, sharing, collecting, playing, etc.

It should be noted that when the client outputs the historical downloaded media data, it can be output in a paging mechanism. For example, if the historical downloaded media data to be output is song information of multiple songs, the song information can be displayed in pages, and the terminal screen can display the song information of multiple songs on one page.

In an embodiment of the present invention, after a communication account logs in to a client, a media data acquisition request sent by the client is received, the acquisition request carries the communication account, and according to the acquisition request, historical downloaded media data to be outputted associated with the communication account is acquired, and the acquired historical downloaded media data to be outputted is returned to the client for output. This method enables the communication account to output historical downloaded media data associated with the communication account after logging in to a client on different platforms, which is convenient for users to use and has strong practicality.

Please refer to FIG. 2 , which is a flow chart of a data output method provided by an embodiment of the present invention; the method may include the following steps S200 to S203 .

S200, after a communication account is logged in on a client, receiving a media data acquisition request sent by the client, the acquisition request carrying the communication account;

Please refer to step S100 of the embodiment of FIG. 1 for step S200 of the embodiment of the present invention, and will not be described in detail here.

S201 : Reading historical downloaded media data identified by a data identifier of each historical download record in the plurality of historical download records in the historical download list corresponding to the communication account from a storage system.

In a specific embodiment, after a user downloads an audio or video file through their communication account on a terminal client, the client transmits the communication account and the data identifier of the audio or video file to the server's backend service program. As shown in FIG5 , this means that the communication account and data identifier are transmitted to the web server's backend server. Alternatively, the client can transmit the communication account and data identifier to the backend service program via CGI. The server's backend service program adds the data identifier to a historical download list associated with the communication account. This historical download list stores all historical download records for the communication account. A historical download record includes two fields: one field stores the data identifier of the downloaded audio or video file (e.g., a song ID), and the other field stores the download time. Each download performed using the communication account generates a historical download record. As shown in Figure 5, the download history list associated with each communication account is stored in CKV. CKV stores the download history list associated with each communication account. Currently, CKV stores a maximum of 10,000 download history records per communication account. When the number of download history records exceeds 10,000, the most recent download history records are migrated to Tlist, a component provided by the Tencent Cloud platform. Tlist is a general-purpose list storage system that provides flexible list operation interfaces (such as sorting, classification, and filtering), supports unlimited list length, and offers list application peripherals such as custom indexing.

Optionally, the historical download list associated with each communication account can be encapsulated through the application layer protocol. When it is necessary to obtain the historical downloaded media data to be output associated with the communication account, the historical download list associated with the communication account encapsulated by the application layer protocol is first decoded to obtain specific information of the historical download list, thereby further obtaining the historical downloaded media data to be output.

In an embodiment of the present invention, the server's storage system stores historically downloaded media data for various audio and video files. As shown in FIG5 , the storage system stores various song information, and the song information application server retrieves the corresponding song information from the storage system based on the data identifier. The data identifier of an audio or video file is typically used to identify the historically downloaded media data for that audio or video file in the storage system. Therefore, simply obtaining the data identifier allows the historically downloaded media data to be obtained from the server's storage system. Specifically, the historically downloaded media data identified by the data identifier in the historical download list stored in the CKV can be retrieved from the server's storage system. Users can obtain relevant information about the historically downloaded audio or video files from the historically downloaded media data.

Optionally, if the historical downloaded media data to be output includes the historical downloaded media data identified by the data identifiers of all historical download records in the historical download list;

When a media data acquisition request is received from the client, the server's background application reads the historical download list associated with the communication account from the server's download list storage, and obtains the historical download media data to be output through the data identifier of each historical download record in the historical download list. The media data can be the name, author, creation time, etc. of the audio and video file.

S202: Return the historical downloaded media data to be output to the client for output.

For step S202 of the embodiment of the present invention, please refer to step S102 of the embodiment of FIG. 1 , which will not be described in detail here.

S203: Count the total number of records in the plurality of historical download records in the historical download list, and return the total number of records to the client for output.

In a specific embodiment, in order to enable users to quickly know the number of historical download records, the server counts the total number of historical download records in the historical download list and returns the total number of records to the client. After the client receives the total number of records, it can output it, and the output method can be display.

In an embodiment of the present invention, after a communication account logs in to a client, a media data acquisition request sent by the client is received, the acquisition request carries the communication account, and according to the acquisition request, historical downloaded media data to be outputted associated with the communication account is acquired, and the acquired historical downloaded media data to be outputted is returned to the client for output. This method enables the communication account to output historical downloaded media data associated with the communication account after logging in to a client on different platforms, which is convenient for users to use and has strong practicality.

Please refer to FIG. 3 , which is a flow chart of a data output method provided by an embodiment of the present invention. The method may include the following steps S300 to S303 .

The receiving module 100 is configured to receive a media data acquisition request sent by a client after the communication account is logged in to the client, wherein the acquisition request carries the communication account;

In a specific embodiment, the client can be a media client, such as various music clients or video clients. After installing the client on various terminals, users can freely download various multimedia files, such as audio and video files, from the client using their communication accounts. To ensure that users can view the media data of previously downloaded multimedia files after logging into their communication accounts on various terminals, once the communication account is logged into the client, the client sends a media data acquisition request to the server, which carries the communication account. Optionally, the client can send the acquisition request to the server via a Common Gateway Interface (CGI), and the server can be a web server. As shown in FIG5 , the client sends the media data acquisition request to the web server. CGI is an interface standard between external applications and web servers, and is a procedure for transmitting information between external applications and web servers.

In the embodiment of the present invention, the media data may be the name, author, creation time, audio and video data of the multimedia file, etc. The client that the communication account logs into is not limited to the terminal platform. As long as the communication account logs into the client on the terminal platform, a media data acquisition request is sent to obtain historically downloaded media data.

An acquisition module 101 is configured to acquire, according to the acquisition request, historical downloaded media data to be outputted and associated with the communication account;

In a specific embodiment, the server acquisition module 101 parses the communication account carried in the acquisition request sent by the client, and obtains the historical downloaded media data associated with the communication account to be output. The historical downloaded media data associated with the communication account to be output is the media data of multimedia files historically downloaded by the communication account on various terminal platforms. The media data of the multimedia files can be attribute information of the multimedia files. For example, if the multimedia file is a song, the media data may include the song title, song album, and lyrics. As shown in Figure 4, the client displays the titles and artists of each song historically downloaded by the communication account.

In an embodiment of the present invention, the historical downloaded media data to be output can be the media data of all multimedia files in the download history associated with the account, or the media data of a portion of multimedia files in the download history associated with the communication account. For example, if the historical downloaded media data to be output is the media data of historically downloaded songs, the historical downloaded media data to be output can be the titles and artists of all songs downloaded by the communication account, or the titles and artists of a portion of songs downloaded by the communication account.

Optionally, if the client sends a media data acquisition request to the server via CGI, CGI retrieves the historical downloaded media data to be output associated with the communication account from the cloud distributed storage (Cloud Key Value, CKV). The historical downloaded media data may be encapsulated via an application layer protocol. When obtaining the historical downloaded media data to be output associated with the communication account, the historical downloaded media data encapsulated via the application layer protocol is decoded to obtain the specific media data for each historical download, and the requested historical downloaded media data to be output is then returned to the client.

There are three optional implementations for the acquisition module 101 to acquire the historical downloaded media data to be output:

In a first optional implementation manner, if the historical downloaded media data to be output includes the historical downloaded media data identified by the data identifiers of all historical download records in the historical download list;

The acquisition module 101 is specifically configured to read, from a storage system, the historical downloaded media data identified by the data identifier of each historical download record in the plurality of historical download records in the historical download list corresponding to the communication account.

In a specific embodiment, after a user downloads an audio or video file through their communication account on a terminal client, the client transmits the communication account and the data identifier of the audio or video file to the server's backend service program. As shown in FIG5 , this means that the communication account and data identifier are transmitted to the web server's backend server. Alternatively, the client can transmit the communication account and data identifier to the backend service program via CGI. The server's backend service program adds the data identifier to a historical download list associated with the communication account. This historical download list stores all historical download records for the communication account. A historical download record includes two fields: one field stores the data identifier of the downloaded audio or video file (e.g., a song ID), and the other field stores the download time. Each download performed using the communication account generates a historical download record. As shown in Figure 5, the download history list associated with each communication account is stored in CKV. CKV stores the download history list associated with each communication account. Currently, CKV stores a maximum of 10,000 download history records per communication account. When the number of download history records exceeds 10,000, the most recent download history records are migrated to Tlist, a component provided by the Tencent Cloud platform. Tlist is a general-purpose list storage system that provides flexible list operation interfaces (such as sorting, classification, and filtering), supports unlimited list length, and offers list application peripherals such as custom indexing.

Optionally, the historical download list associated with each communication account can be encapsulated through the application layer protocol. When it is necessary to obtain the historical downloaded media data to be output associated with the communication account, the historical download list associated with the communication account encapsulated by the application layer protocol is first decoded to obtain specific information of the historical download list, thereby further obtaining the historical downloaded media data to be output.

In an embodiment of the present invention, the server's storage system stores historically downloaded media data for various audio and video files. As shown in FIG5 , the storage system stores various song information, and the song information application server retrieves the corresponding song information from the storage system based on the data identifier. The data identifier of an audio or video file is typically used to identify the historically downloaded media data for that audio or video file in the storage system. Therefore, simply obtaining the data identifier allows the historically downloaded media data to be obtained from the server's storage system. Specifically, the historically downloaded media data identified by the data identifier in the historical download list stored in the CKV can be retrieved from the server's storage system. Users can obtain relevant information about the historically downloaded audio or video files from the historically downloaded media data.

When receiving a media data acquisition request from the client, the acquisition module 101 reads the historical download list associated with the communication account from the server's download list memory through the server's background application, and obtains the historical download media data to be output through the data identifier of each historical download record in the historical download list. The media data can be the name, author, creation time, etc. of the audio and video file.

In a specific embodiment, if the media data acquisition request includes a target number of historically downloaded media data pre-output by the client (for example, including the number of pre-output music tracks), the sorting unit 1010 sorts the historical download records in the historical download list according to the chronological order of their download times, with the earlier ones being historical download records that are further away from the current moment and the later ones being historical download records that are closer to the current moment. The target historical download records that are ranked last in the target number are acquired, i.e., the preset number of target historical download records closest to the current moment. The acquisition unit 1011 acquires the historically downloaded media data to be output from the storage system based on the data identifiers in the target historical download records.

In a third optional implementation manner, if the acquisition request includes historical downloaded media data of a target time period pre-output by the client;

The acquisition module 101 is specifically configured to select a target historical download record whose download time falls within the preset time period from the historical download list, and acquire the historical download media data to be output from the storage system according to the data identifier in the target historical download record.

In a specific embodiment, if the media data acquisition request includes historical downloaded media data pre-output by the client for a target time period, for example, the client pre-outputs historical downloaded media data between 12:00 PM on June 11, 2015, and 12:00 PM on June 13, 2015, the acquisition module 101 selects a target historical download record whose download time falls within the preset time period from the historical download list. The target historical download record may include multiple historical download records or only one historical download record. The historical downloaded media data to be output is acquired from the storage system based on the data identifier in the target historical download record. For example, if the data identifier is a song identifier, the song information identified by the song identifier is acquired from the storage system.
