Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an aspect of an embodiment of the present invention, a method for processing data is provided. In this embodiment, the data processing method can be applied to a hardware environment formed by the terminal and the server shown in fig. 1. As shown in fig. 1, an application 101 establishes a local server 102, and the local server 102 is connected to a remote server 103 via a network. Such networks include, but are not limited to: the terminal 101 may be a mobile phone terminal, or may also be a PC terminal, a notebook terminal, or a tablet terminal.
Fig. 2 is a flow of a data processing method according to an embodiment of the present invention. As shown in fig. 2, the data processing method includes:
step S200, the local server of the target application acquires the identification of the target file in the first network address sent by the multimedia control.
The target application may be the application 101 shown in fig. 1. The multimedia control can be a control used in the terminal to play the multimedia file. For example, the target application is a news client shown in fig. 3 for displaying news, the multimedia widget is program code for playing an audio file, the news client calls the multimedia widget to play the multimedia file, and the playing interface of the multimedia file is shown in fig. 4. For example, the multimedia control may obtain, through the local server, a multimedia file such as an audio file or a video file stored on the remote server, and play the obtained multimedia file.
The target file may be a file that the target application calls the multimedia control to play, and the target file may be a multimedia file such as an audio file or a video file. The identification of the target file may be used to indicate the name, number, etc. of the target file. The storage address of the target file is stored in the m3u8 file. Fig. 5 shows the storage content of the m3u8 file. m3u8 is a multimedia playlist file format. The m3u8 file is a text file with the content opened as shown in fig. 5, and has many audio file addresses therein, such as the content in the red box of the figure in fig. 5. For example:
http:// tfp. gtimg. com/tfp/dd/audio/KMJH8nEURbrsu0nTq33.0. mp3, etc., the player will play the audio files listed in m3u8 in sequence.
As shown in fig. 5, any one of the addresses in the black box indicates a storage address of one target file, for example, kmjjjjjj8eurbrsu 0ntg33.0 in the storage address is an identifier of one target file, and kmjjjjjjjj8eurbrsu 0ntg33.1 and kmjjjjjjjjjjjjjjjjjjjjh 0 in the other storage addresses are identifiers of two target files, respectively.
The first network address is an address pointing to a local server, unlike the storage address shown in fig. 5. The first network address may be http://127.0.0.1/a.keyid xxx & code xxx. Where 127.0.0.1 points to the local server, the first network address is used to request a key for decoding the encrypted audio file stored at the storage address in m3u 8. Id ═ xxx in the first network address represents the identifier of the target file, and code ═ xxx is a check code of the first network address, and is used for checking whether the first network address is generated by the local server. It should be noted that the web address is used to illustrate information that the first network address can carry, and the form is not limited to the above example.
Step S202, the local server sends a first request to a remote server according to the identification of the target file, wherein the first request is used for requesting to acquire the password file of the target file.
The remote server stores the target file, and the target file is transmitted in an encrypted form, so that the target file is prevented from being captured and played in the transmission process. Therefore, after obtaining the encrypted target file, the multimedia control needs to decode the encrypted target file by using the password file of the target file. The object files recorded in the m3u8 file shown in fig. 5 can all be decrypted with the same password file.
The encryption scheme of the target file is described in the m3u8 file shown in fig. 5, and as shown in the box shown in fig. 6, the encryption scheme is: EXT-X-KEY: METHOD AES-128.
Step S204, the local server receives the encrypted password file sent by the remote server according to the first request.
Step S206, the local server decrypts the encrypted password file to obtain the password file.
The local server and the remote server agree on encryption rules in advance, for example, using asymmetric encryption. And after receiving the encrypted password file, the local server decrypts the encrypted password file by using an agreed encryption rule to obtain the password file. In the process of transmitting the password file by the remote server and the local server, the password file is in an encrypted state, so that even if the encrypted password file is intercepted or captured, the security of the password file is ensured because decryption cannot be performed.
Step S208, the local server sends the password file to the multimedia control, where the password file is used to decrypt the encrypted target file in the multimedia control.
And after the local server acquires the password file, the password file is sent to the multimedia control. Because the local server and the multimedia control are both arranged in the same terminal, the password file transmitted between the local server and the multimedia control cannot be leaked, and the security of the password file is further ensured. The multimedia control decrypts the target file by using the password file, thereby playing the target file.
The password file transmitted between the local server and the remote server is in an encrypted state, so that the security of the password file in the transmission process is ensured, and the password file is requested to the remote server through the local server, so that the target application can directly call the multimedia control to play the target file without changing the multimedia control, the flexibility of the multimedia control is improved, the technical problem that the security of the client plays the multimedia file is poor in the prior art is solved, and the technical effect of improving the security is achieved.
