Detailed Description
In order to provide convenience for user operation and reduce limitation of cache capacity when a user accesses a network hard disk, embodiments of the present application provide a method, an apparatus, a terminal device, and a medium for operation control.
First, some terms referred to in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
1. The terminal equipment: the electronic device can be mobile or fixed, and can install various applications and display entities provided in the installed applications. For example, a mobile phone, a tablet computer, a vehicle-mounted device, a Personal Digital Assistant (PDA), or other electronic devices capable of implementing the above functions.
2. Network hard disk: the server room divides a certain disk space for users, provides file management functions such as storage, access, backup and sharing of files for the users free or charged, and has high-level disaster recovery backup all over the world. Such as a mesh disk, cloud disk, and cloudiness, etc.
3. Virtual disk: the method is to use the technology of virtualizing one or more disks in the memory to disguise files, network files, memories and the like as disks, so that a user feels like a disk of a real disk and the disk is called a virtual disk.
4. And (4) carrying out disc character writing: is the identifier of the DOS, WINDOWS system to the disk storage device. Typically using 26 english characters plus a colon. Since early PCs were typically equipped with two floppy disk drives, "a: "and: "B: "these two drive letters are used to indicate floppy drives and hard disk devices start with the letter C, and go through Z:. For UNIX, LINUX systems, there is no notion of drive letter, but the notions of directory and path are the same.
5. A file system: the software mechanism is responsible for managing and storing file information in an operating system, and particularly responsible for establishing files, storing, reading, modifying and dumping files, controlling the access of the files, cancelling the files and the like for a user. The file system is composed of three parts of an interface of the file system, a software set for manipulating and managing objects, and the objects and attributes.
A user usually accesses the network hard disk through a network hard disk application program (i.e., a network hard disk client), but since different application programs have different operation modes, the user needs to learn about the network disk operation of the network hard disk application program first, which brings inconvenience to the user and reduces the processing efficiency of the user. If the network hard disk is accessed by adopting the virtual disk, the capacity of the cache area is greatly limited because the cache space of the virtual disk is fixed and unchangeable, and the cache requirement of a user cannot be met.
To sum up, the embodiment of the present application provides a technical solution for operation control, which is to create a virtual disk for a network hard disk when a user logs in the network hard disk, where the virtual disk includes a drive letter, a cache area created in a largest partition, and a file system; when the operation instruction of the designated type sent by the user is determined to be received, the file system obtains the current available capacity in the hard disk partition through a pre-registered disk information interface, updates the capacity configuration information of the virtual disk based on the current available capacity of the hard disk partition, and executes the operation instruction of the designated type aiming at the virtual disk after the updated configuration. Therefore, the capacity of the cache region can be continuously updated according to the current available capacity of the hard disk partition, and the capacity limit of the cache region is reduced.
The operation control method provided by the embodiment of the application can be applied to terminal equipment, and the terminal equipment can be a mobile phone, a tablet Personal computer, a PDA (Personal Digital Assistant), and the like.
Fig. 1 shows a system architecture diagram for operation control. Referring to fig. 1, the operation control system includes a virtual disk and a network disk server. The virtual disk comprises a drive letter, a file system and a cache region.
When a user logs in the network hard disk, the terminal device creates a virtual disk for the network hard disk, so that the user can operate the virtual disk like operating a local disk. The virtual disk is a technology of virtualizing one or more disks in a memory, namely files, network files, memories and the like are disguised as disks, so that a user feels like a disk of a real disk.
When the terminal equipment creates the virtual disk, the terminal equipment allocates an idle drive letter to the virtual disk, and a user can access the virtual disk through the drive letter. The drive letter is the identifier of the DOS and WINDOWS systems to the disk storage device.
A cache area: and creating a storage space for the terminal equipment in the hard disk partition for the virtual disk. It should be understood that the linux operating system treats all devices as files, and integrates the resources of the whole computer into a large file directory, so that the cache area corresponds to the cache area.
The file system is a software mechanism in the operating system responsible for managing and storing file information, and specifically, it is responsible for creating files, storing, reading, modifying, dumping files, controlling file access, revoking files, and the like for users. The file system is composed of three parts of an interface of the file system, a software set for manipulating and managing objects, and the objects and attributes. The virtual disk redirects the operation aiming at the disk identifier to the cache region through the file system, presents the operation result to the user, calls a pre-registered disk information interface, acquires the current available capacity of the hard disk partition, and updates the capacity configuration information of the cache region based on the current available capacity of the hard disk partition.
The network disk server is a server which integrates dispersed and different storage resources and provides uniform storage service for users through technologies such as network transmission, distributed computation, cluster service and the like.
Those skilled in the art will appreciate that fig. 1 is merely an example of a terminal device and is not limiting of terminal devices and may include more or fewer components than those shown, or some of the components may be combined, or different components.
In the embodiment of the present application, before implementing the method for operation control, a virtual disk is created for a network hard disk accessed by a user, where when creating a virtual disk for a network hard disk, the following steps may be performed:
firstly, when terminal equipment determines that a login instruction of a user for logging in a network hard disk is received, a hard disk partition is searched locally, a cache area is created in the hard disk partition, and the cache area is used as a cache area of a virtual disk. Then, the terminal device determines the selected free drive letter (e.g., Z-drive) as the drive letter of the virtual disk, and binds the drive letter with the cache area. And finally, the terminal equipment loads a file system for the virtual disk and registers an operation interface which can be called by the file system.
Optionally, when the terminal device creates the drive, the drive may be created based on the user token through the DefineDosDevice function. In this way, when another user (e.g., a hacker) remotely checks the device of the current user, the other user cannot remotely log in the virtual disk of the current user through the device of the current user because the user token of the current user cannot be obtained.
Alternatively, the terminal device may create a file system DeviceObject using an iocreatedevicececess function, and load the file system for the drive through a DefineDosDevice function.
Optionally, the operation interface at least includes a disk information interface, and may further include any one or any combination of the following interfaces: new interfaces, copy interfaces, move interfaces, delete interfaces, and rename interfaces. The disk information interface is used for acquiring the current available capacity of the hard disk partition. The new interface, the copy interface, the move interface, the delete interface and the rename interface are used for executing operations of new creation, copy, move, delete, rename and the like.
Therefore, the user can operate the virtual disk like operating the local disk without learning a new operation mode, convenience is provided for the user operation, and the file processing efficiency of the user is improved.
Referring to fig. 2, a flowchart of an implementation of the method for operation control according to the present application is shown, and the specific implementation flow of the method is as follows:
step 200: and the terminal equipment receives an operation instruction sent by a user aiming at the virtual disk.
Step 201: the terminal device judges whether the operation instruction is an operation instruction of a specified type, if so, step 202 is executed, otherwise, step 204 is executed.
Specifically, the specified type of operation instruction is an instruction that causes a change in the capacity of the cache file. Such as a download instruction, a modification instruction, a copy instruction, a new instruction, a file viewing instruction, a file saving instruction, a network disk viewing instruction, and the like. Non-specified type of operation instruction, such as a synchronous delete instruction, or an edit instruction.
Step 202: and the terminal equipment acquires the current available capacity in the hard disk partition to which the virtual disk belongs.
Specifically, the terminal device calls a disk information interface through a file system to obtain the current available capacity in the hard disk partition.
A cache area of a virtual disk is created in the hard disk partition. And the virtual disk caches data through the cache region.
In this way, the disk information interface can be registered in the file system in advance, so as to obtain the capacity information in the hard disk partition through the disk information interface.
Step 203: the terminal equipment determines to update the capacity configuration information of the virtual disk based on the current available capacity.
Specifically, the terminal device obtains the current used capacity of the virtual disk, i.e., the cache region, through the file system, determines the sum of the used capacity and the current available capacity, and sets the capacity configuration information of the cache region as the sum.
Therefore, the capacity of the cache region can be continuously updated according to the current available capacity in the hard disk partition, and the limit of the virtual disk cache capacity is reduced.
Step 204: and the terminal equipment redirects the operation instruction to the cache area.
Specifically, the file system serves as a medium between the drive letter and the cache region, the file system transfers the operation instructions to the cache region, and the user can only see the drive letter, the directory and the like in the application layer interface, but cannot see information such as a specific path of the cache region.
Therefore, the cache region can be hidden and protected, and the data security is improved.
Step 205: and the terminal equipment executes the operation instruction.
Specifically, when step 205 is executed, the following methods may be adopted:
the first mode is as follows: if the specified type operation instruction is a network disk viewing instruction, sending a file index request message to a network disk server, and receiving network disk file description information returned by the network disk server; then, based on the description information of the network disk file, generating a mirror image file directory in the cache region, and presenting the mirror image file directories of all network disk files in the network disk server to the user through the disk identifier of the virtual disk.
The network disk file description information is information describing each network disk file in the network disk server. The mirror image file directory is a directory index for describing the network disk files in the network disk server. The network disk file description information at least comprises: storage path, file name, file type, and file size, etc.
Therefore, even if the network disk files are not downloaded in the cache region, a user can check all files in the network disk server through the image file directory presented by the virtual disk, consumption of system resources is reduced, a large amount of time cost consumed by data synchronization is reduced, and the file processing efficiency is improved.
The second way is: if the specified type of operation instruction is a file viewing instruction, whether a user-specified viewing file exists in the cache region is judged through the file system, if so, the viewing file is accessed through the file system, and otherwise, the viewing file is downloaded from the network disk server through the file system according to the mirror image file directory.
Furthermore, if the file is large, the file can be uploaded and downloaded in a multithreading granularity uploading and granularity downloading mode, so that the transmission efficiency is improved, and light-weight office is realized.
Therefore, the corresponding file can be downloaded only when the user checks the file, data synchronization is not needed to be carried out on all the files, the efficiency is improved, and the waste of flow and storage resources is reduced.
The third mode is as follows: if the specified type of operation instruction is a file saving instruction, storing a saved file specified by a user in a cache region through a file system, and uploading the saved file to a network disk server. And then, the network disk server stores the received storage file, so that the network disk server and the virtual disk are synchronously stored.
The fourth mode is as follows: if the specified type of operation instruction is a new instruction, calling a pre-registered new interface through the file system, sending a file operation request to the network disk server, and executing the new instruction in the cache region when determining that a file operation response message returned by the network disk server based on the file operation request is received.
The fifth mode is as follows: if the specified type of operation instruction is a copy instruction, a copy interface is called through a file system, a file operation request is sent to the network disk server, and the copy instruction is executed in the cache region when a file operation response message returned by the network disk server based on the file operation request is determined to be received.
Further, for the non-specific type operation instruction, such as a synchronous deletion instruction or an editing instruction, when the terminal device executes the non-specific type operation instruction, the following manners may be adopted:
the first mode is as follows: if the non-specified type operation instruction is a synchronous deletion instruction sent by the network disk server, acquiring network disk file description information contained in the synchronous deletion instruction, and acquiring local file description information of a cache file in a cache region; the local file description information is information describing each cache file in the cache region. Then, comparing the description information of the network disk file with the description information of the local file, and according to the comparison result, when at least one cache file contained by the network disk file exists in the cache region, synchronously deleting the extra cache files in the cache region compared with the cache files in the network disk server.
Thus, when the network disk server deletes the file, even if the user downloads the file in the cache region, the file in the cache region can be deleted, and synchronization of the deleted file is realized.
The second way is: if the non-specified type operation instruction is an editing instruction, a corresponding editing request is sent to the network disk server through an editing interface corresponding to the editing instruction called by the file system, and the editing instruction is executed in the cache region when an editing response message returned by the network disk server based on the editing request is determined to be received.
The editing interface is a mobile interface, a deleting interface or a renaming interface. The editing instructions correspond to the editing interfaces one by one.
In this way, the corresponding operation instructions such as moving, deleting and renaming can be executed through the moving interface, the deleting interface and the renaming interface which are registered in the file system in advance.
Step 206: and the terminal equipment presents the operation result to the user.
Specifically, the terminal device returns an operation result of executing the operation instruction in the cache region to the application layer of the virtual disk through the file system, and presents the operation result to the user.
In the embodiment of the application, before the specified type of operation instruction is executed, the capacity of the virtual disk is adjusted according to the current available capacity of the hard disk partition, so that the limitation on the cache area of the virtual disk is reduced.
Fig. 3a is a schematic diagram illustrating an operation principle of a virtual disk according to an embodiment of the present invention. The drive letter of the virtual disk is positioned at an application layer, and the file system is positioned at a drive layer. The terminal equipment receives an operation instruction issued by a user through the application layer, executes the operation instruction through the file system, and presents an execution result of the file system through the application layer. And the file system in the drive layer performs data interaction with the network disk server based on the operation instruction and returns an interaction result to the application layer, or returns an operation result of executing the operation instruction in the cache region to the application layer and presents the operation result through the application layer.
The above embodiments are further illustrated below using a number of application scenarios.
FIG. 3b is a diagram of an exemplary embodiment of a disc character interface. For example, after a user double-clicks a disk identifier 'digital cloud disk (Z:'), a file system receives a network disk viewing instruction sent by an application layer, performs capacity configuration updating on a cache area in a virtual disk according to the current available capacity in a hard disk partition of the virtual disk, sends a file index request message to a network disk server, generates a mirror image file directory in the cache area based on network disk file description information of each network disk file returned by the network disk server, returns an execution result to the application layer, and displays the mirror image file directory in the disk identifier 'digital cloud disk (Z:').
As another example, the user is in a directory: after double-clicking a changelog.txt file in a computer digital cloud disk (Z:) personal database test, a file system determines that the changelog.txt file does not exist in a cache region based on a received file viewing instruction, performs capacity configuration updating on the cache region in a virtual disk according to the current available capacity in a hard disk partition of the virtual disk, and downloads the changelog.txt file to the cache region through a network disk server. And the terminal equipment accesses the changelog.txt file through the file system, and then presents the file content of the changelog.txt file to the user.
As another example, the user is in a directory: the computer selects changelog1.txt files from the digital cloud disk (Z:) > personal database > test and clicks a delete button, and the terminal equipment sends a file delete request containing the changelog1.txt to the network disk server through a corresponding delete interface based on a received delete instruction through a file system. And the network disk server deletes the changelog1.txt file locally based on the file deletion request and sends a deletion response message to the terminal equipment. When the terminal equipment receives the response message of successful deletion, the terminal equipment deletes the changelog1.txt file in the cache region, so that the user can see the directory: the computer deletes changelog1.txt file in digital cloud disk (Z:) personal database (personal database) test.
