Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
In the related art, the file system of the electronic device is usually customized based on a specific operating system of the device, for example, an Ext4 file system customized based on a Linux operating system, file systems such as an Exfat, a Ntfs and a Fat32 file system customized based on a Windows operating system, and an AFS file system customized based on an IOS operating system. However, since the file system is customized based on various operating systems, cross-platform data acquisition and storage cannot be realized, for example, a first electronic device with an android operating system cannot directly acquire and parse data from a second device with a Windows operating system, which obviously brings great inconvenience to subsequent data application and the like. The present disclosure aims to solve at least one of the technical problems in the related art to some extent, and for this reason, embodiments of the present disclosure provide a data acquisition method, a data storage method, an apparatus, a device, and a storage medium.
FIG. 1 is a flow chart illustrating a method of data acquisition according to an exemplary embodiment; the method of the present embodiment may be applied to a first device that may include a processor for storing received data and a memory that may be used to execute instructions for data processing; the first device may comprise a server running independently, a distributed server, or a server cluster consisting of a plurality of servers. It should be noted that the first device may be understood as a terminal device, for example, a television device, a computer device, a smart phone, a tablet computer, a wearable device, etc., and may also be understood as an operating system or a platform included in the terminal device. As shown in fig. 1, the method includes the following steps S101-S103:
in step S101, a setting executable format file is acquired.
In this embodiment, the first device obtains a setting executable format file stored in advance by the second device. The file with the executable format comprises a file stored by a file storage function which is created by the second device in advance based on a specific programming language, and the operating systems of the first device and the second device are different. The particular programming language may be java, c++, python, etc.
The following examples illustrate the programming language python. Python is a cross-platform interpreted programming language, all contents of which are free of charge and can be directly downloaded for use, and codes of the Python can be modified. Wherein Python memory management is automatically completed, and operators only need to pay attention to the program itself, and do not need to pay attention to memory management. Most importantly, it has good cross-platform and portability, and can be transplanted to most platforms for use by operating systems such as Windows, macOS, linux, android and IOS.
In some embodiments, the format of the set executable format file may be predefined, and the format of the set executable format file may be predefined as desired. For example, the above-described setting executable Format file may be defined as a Cross-Platform SMART DEVICE DATA Format (CDF) file, which is suffixed with a. CDF.
In other embodiments, the format and the suffix of the executable format file are associated with the actual usage scenario, and may be set based on the actual usage scenario device, for example, in a smart tv scenario, the executable format file may be a tv format file, and the tv is used as the suffix.
The storage manner of the setting executable format file may be referred to the embodiment shown in fig. 3 below, and will not be described in detail here.
In step S102, a file parsing method created in advance is called to parse the file with the set executable format, so as to obtain a file structure directory.
In this embodiment, after the setting executable format file is obtained from the second device, a file parsing manner created in advance based on python may be invoked to parse the setting executable format file, so as to obtain a file structure directory.
In an embodiment, a function library created based on python for parsing the set executable format file may be pre-installed on the first device, and after the set executable format file is obtained from the second device, a file parsing function in the function library may be called to parse the set executable format file, so as to obtain a file structure directory. For example, the first device may call a file reading function created in advance based on python, such as "read_cdf", and read the file with the executable format to obtain a file structure directory, and further may access the directory and attribute values created before through the file handle.
In this embodiment, the file structure directory may include at least one Section directory (Section), where the Section directory includes at least one database directory (Dataset). For example, the structure of the CDF file is as follows:
further, the database directory (Dataset) may include original Data (Data values) and Metadata (Metadata), where the Metadata may include at least one of the following:
DATASPACE: rank and dimension of the original data;
datatype: the type of the original data, such as video, audio, text, configuration parameters, etc.;
Properties: attributes of the original data, such as the case of data chunking (granularity), compression (Chunk and Compressed), etc.;
Attributes: custom properties of the raw data.
For example, the structure of the database directory (Dataset) is as follows:
in step S103, in response to receiving a data acquisition instruction carrying handle information, target data corresponding to the handle information is acquired from the file structure directory.
In this embodiment, after a file analysis mode created based on python is invoked to analyze the set executable format file in advance to obtain a file structure directory, target data corresponding to handle information may be obtained from the file structure directory in response to receiving a data obtaining instruction carrying the handle information.
In some embodiments, the handle information may include a segment identifier of the segment directory and a database identifier of the database directory, where the target data corresponds to the segment directory in the file structure directory, and the acquiring the target data corresponding to the handle information from the file structure directory in step S103 may include:
And acquiring target data corresponding to the segment identifier and the database identifier from the file structure directory. For example, the corresponding target data may be acquired from the file structure directory based on instructions such as "fd.section", "fd.section (number)", "fd.section (" video ")," and the like, where "section", "number" and "video" are handle information corresponding to the desired target data.
As can be seen from the foregoing description, in the method of this embodiment, the set executable format file is obtained, where the set executable format file includes a file stored by a second device in advance based on a created file storage function, the operating systems of the first device and the second device are different, and a file analysis mode created in advance is invoked to analyze the set executable format file to obtain a file structure directory, and further, in response to receiving a data acquisition instruction carrying handle information, target data corresponding to the handle information is obtained from the file structure directory, so that analysis of the set executable format file obtained from the second device with a different operating system can be implemented, further, obtaining required target data based on the handle information in the data acquisition instruction can be implemented, limitation that data cannot be directly analyzed and obtained between devices with different operating systems in related technologies can be implemented, cross-platform data analysis and acquisition can be achieved, portability of a data acquisition scheme can be improved, and efficiency of subsequently applying the acquired data can be improved.
FIG. 2 is a flow chart illustrating a method of data acquisition according to yet another exemplary embodiment; as shown in fig. 2, the method includes the following steps S201 to S205:
in step S201, a setting executable format file is acquired.
Wherein the set executable format file comprises a file stored by the second device in advance based on a file storage function created by python, the operating systems of the first device and the second device being different.
In step S202, a file parsing method created in advance is called to parse the file with the set executable format, so as to obtain a file structure directory.
In step S203, a pre-created handle information display function is called to display the handle information corresponding to each data in the file structure directory.
In this embodiment, when the first device invokes a file parsing manner created based on python in advance to parse the set executable format file to obtain a file structure directory, in order to clearly display handle information corresponding to each data in the file structure directory to a user, a handle information display function created based on python in advance, such as "fd.
In step S204, a data acquisition instruction carrying handle information, which is sent based on the handle information and is displayed, is received.
It can be understood that when the handle information display function created based on python in advance is called, after the handle information corresponding to each data in the file structure directory is displayed, the user can determine the handle information corresponding to the target data required by the user based on the handle information corresponding to each data currently displayed, and further can input a data acquisition instruction carrying the handle information corresponding to the target data in the first terminal device, so that the first terminal device can receive the data acquisition instruction to execute the subsequent steps.
In step S205, in response to receiving a data acquisition instruction carrying handle information, target data corresponding to the handle information is acquired from the file structure directory.
The explanation and explanation of steps S201 to S202 and S205 may be referred to the above embodiments, and will not be repeated here.
As can be seen from the above description, the method of the embodiment displays the handle information corresponding to each data in the file structure directory by calling the handle information display function created based on python in advance, and receives the data acquisition instruction carrying the handle information sent based on the displayed handle information, which can be implemented to clearly display the handle information corresponding to each data in the file structure directory for the user, and is convenient for the user to determine the handle information corresponding to the target data required by the user, thereby laying a foundation for inputting the data acquisition instruction carrying the handle information corresponding to the target data in the first terminal device, and improving the accuracy of acquiring the target data from the file structure directory based on the data acquisition instruction.
FIG. 3 is a flowchart illustrating a method of data storage according to an exemplary embodiment; the method of the present embodiment may be applied to a second device comprising a processor and a memory for storing received data, the processor being operable to execute instructions for data processing; the second device may comprise a server running independently, a distributed server, or a server cluster consisting of a plurality of servers. It should be noted that the second device may be understood as a terminal device, for example, a television device, a computer device, a smart phone, a tablet computer, a wearable device, etc., and may also be understood as an operating system or a platform included in the terminal device. The operating systems or platforms of the second device and the first device may be different. As shown in fig. 3, the method includes the following steps S301 to S303:
In step S301, handle information of target data to be stored is determined.
In this embodiment, before storing the target data, the handle information corresponding to the target data may be determined.
For example, it may be determined that the above-described target data corresponds to a segment identification of a segment directory (i.e., identification information of a Section portion) and a database identification of a database directory (i.e., identification information of a Dataset portion) in a file structure directory.
In step S302, the target data and the handle information are written to obtain a file structure directory.
In this embodiment, after determining the handle information of the target data to be stored, the target data and the handle information may be written based on python to obtain the file structure directory. For example, target data and corresponding handle information can be written into a blank file structure directory created in advance according to a storage path corresponding to the handle information, so as to obtain a written file structure directory.
For example, if the handle information of the target data is "section_1 (" dataset_1_1 ")", the target data may be written into a database directory identified as "dataset_1_1" under a section directory identified as "section_1" in the file structure directory.
In other embodiments, the manner in which the target data and the handle information are written based on python may be referred to as the embodiment shown in fig. 4 described below, which is not described in detail herein.
In step S303, the file structure directory is encapsulated into a set executable format file.
In this embodiment, when writing the target data and the handle information based on python, a file structure directory is obtained, and the file structure directory may be encapsulated into a file with a set executable format. For example, a file storage function created in advance based on python may be called to encapsulate the file structure directory to obtain a set executable format file.
The Format of the setting executable Format file is predefined, such as a Cross-Platform SMART DEVICE DATA Format (i.e., CDF) Format, so that the setting executable Format file can be referred to as a CDF file, where the CDF is a suffix. In this embodiment, the structure of the CDF file may be referred to the embodiment shown in fig. 1, which is not described herein.
