Embodiment three:

In order to describe the present invention more fully, the present invention will now be further explained with reference to specific application examples.

The network architecture of the terminal provided by this embodiment is shown in Figure 3: First, the bottom layer is the physical layer hardware, including the connection methods provided by communication modules such as wired networks and wireless networks; above the physical layer hardware is the TCP/IP protocol layer ; Above TCP/IP is the application layer protocol, such as HTTP (Hypertext Transfer Protocol, hypertext transfer protocol) protocol, REST (Representational State Transfer, representational state transfer) interface belongs to HTTP protocol; general interface hides different protocol layers , differences between different devices and different operating systems, provide a unified file access interface for applications, and applications use common interfaces to implement different applications.

As shown in FIG. 4 , the network file management method provided by this embodiment includes the following steps:

S401: Obtain the file storage attribute of the network file, and construct a local virtual file system;

As shown in Figure 5, the specific implementation of this step includes the following steps:

S501: The user logs in to the cloud disk using the account password, etc.;

According to the cloud disk operator selected by the user, open the cloud disk login interface, and then initiate the login according to the account and password entered by the user. After the verification is passed, the cloud disk login is successful, and the interface shown in Figure 9 is displayed.

The user name and password of the cloud disk are used to log in to the cloud disk space (S41), and a TOKEN value is obtained and stored in the application program. This TOKEN value is used in all subsequent interfaces to facilitate the authentication and judgment of the server.

S502: Obtain the storage information of the cloud disk and the file information of the network file;

Obtain storage information such as the total space size, used space size, and remaining space size of the cloud disk, as well as file information such as the directory structure, file list, and file attributes of network files;

Specifically, after successful login, use the REST interface to obtain the space storage information of the cloud disk, and use the REST interface to obtain the directory structure on the server and save it in the local memory of the application.

S503: Build a virtual file system of the local terminal;

In this embodiment, a new file system is created on the Windows system as a virtual file system corresponding to the cloud disk, and its display interface is the display interface of the virtual file system, as shown in FIG. The system presents information in exactly the same way.

Take the virtual file system created by the Dokan library as an example. The Dokan library contains a user-mode DLL file (dokan.dll) and a kernel-mode file system driver (dokan.sys). Once the Dokan file system driver is installed, it can be used on Windows. An application that creates a file system like a normal file system, using the file system created by the Dokan library is called a file system application. File operation requests from user programs (eg: CreateFile, ReadFile, WriteFile, etc.) will be sent to the Windows input/output subsystem (running in kernel mode), after which the request will be sent to the Dokan file system driver (dokan.sys) , by using the functions provided by the Dokan user-mode library file (dokan.dll), the file system application can register the callback function with the file system driver, and the file system driver will call the registered callback function routine to respond to the request after receiving the request , the processing result of the callback function routine will be returned to the user program. For example: When Windows Explorer requests to create a directory, the request "OpenDirectory" will be sent to the Dokan filesystem driver, which will then call the OpenDirectory callback function routine provided by the filesystem application. The processing result of the function routine is returned to Windows Explorer as a response to the OpenDirectory request. In this embodiment, the Dokan file system driver is like an agent program between the user program and the file system program.

S504: Configure the virtual file system and display it;

Using the Dokan file system, information such as the directory structure, file list, and file attributes on the cloud disk server is mapped to a drive letter under the local Windows system, so that users can browse and operate various files.

The Dokan file system can monitor the addition, deletion, modification and other actions of files under the local Windows operating system. These actions form an interface, and the application program realizes the business connection with the background server in these interfaces, and the REST protocol of HTTP protocol is used to connect these services. interface.

Specifically, after establishing a virtual file system, such as disk E, initialize disk E, and then configure the storage information of the cloud disk as the storage attribute of disk E, as shown in Figure 10, write the file information of the network file to the disk E, as shown in Figure 11.

S402: Configure and enable the local terminal cache;

The local application opens up a memory space for caching file content, and a threshold needs to be set. If the threshold is exceeded, the memory space of the first entered file content needs to be released. Moreover, in practical applications, generally small files (such as 20MB) will be frequently edited, and large files are generally only read, so the memory space does not need to be opened up very much. For large files, use the Dokan file system to directly read Fetching the file content can effectively reduce the network load.

S403: Configure and enable the incremental synchronization algorithm;

The synchronization operation is a relatively complex mechanism, especially in the case of poor network conditions, to solve the synchronization problem, the overhead of network transmission must be reduced, so the incremental synchronization mechanism, that is, the differential synchronization algorithm, must be used. The content transmitted on the network is only Differences, but not all.

The synchronization involved in this step refers to the synchronization of file storage attributes between the remote server and the local terminal cache. The system needs to start a synchronization thread in the background. The operation mode of the thread is as follows: every few minutes, the The content is synchronized with the server.

The incremental synchronization algorithm specifically includes the following:

On the client, the file is divided into multiple blocks according to the block algorithm, and each block calculates an MD5 (Message DigestAlgorithm MD5, the fifth edition of the message digest algorithm, as a strong check value) and a checksum (weak check value), sent to the server.

The server divides the file into blocks according to the same block size from the starting position of the corresponding file, and calculates the MD5 and checksum of each block, and checks to see if it hits a certain checksum given by the client. If it matches, it indicates that the server This piece of content in the file is likely to be consistent with the piece of content in the corresponding client, but since the checksum strength is not enough, MD5 is matched again. If it still matches, it is confirmed that the content is consistent, and then the server sends The segment number that the client matched. For those that cannot be matched, the original content is sent to the client.

The client obtains the matching information given by the server, and constructs a copy that is consistent with the server. If there is a matching block, it copies the corresponding block in the original client file, and if it does not match, appends it.

S404: Monitor and execute the management operation of the user.

The flow chart of the user opening the file is shown in Figure 6, including the following:

For example, when a user needs to open a network file locally, when the user double-clicks a file in the resource manager, he needs to first determine whether the content information of the file already exists in the local cache. If there is already in the cache, read directly from the cache. The content information of the file; otherwise, the content of the file needs to be downloaded from the server using the REST interface.

After downloading the content of the file, before saving, first determine whether the size of the local cache space exceeds the threshold. If so, clear the content of the file with the earliest download time in the cache space, and then save the content of the newly downloaded file to the cache. space; if not, directly save the downloaded file content to the cache space.

The flow chart of the user update file is shown in Figure 7, including the following:

After the user edits the opened file, it needs to be uploaded and updated to the cloud disk. First, the file to be uploaded needs to be obtained, and then the file is divided into several blocks, and the strong check value and weak check value of each block are calculated. After receiving the information, the server also divides the file into the same number of blocks, and the server cyclically detects each block Compare the information with each piece of information sent by the application, first compare whether the weak check value is the same, if not, directly update the content of the block; if it is the same, calculate the strong check value of the block, and then compare the strong check value. Check whether the check values are the same, if not, directly update the content of the block; if they are the same, it means that the strong and weak check values of the block are the same, and the block information is not modified and does not need to be updated. Then continue to judge the information of the next block until all block contents are detected.

The flow chart of user deletion of files is shown in Figure 8, including the following:

If the user wants to delete a file in the virtual file system, he actually wants to delete one or more files in the cloud disk space. First, you need to obtain the file to be deleted, and then call the REST interface to delete the file. If the REST interface returns successfully, update the local cache and delete the file information in the local cache; if the REST interface fails, do nothing.

If the user needs to replace the file, it is a combination of downloading the remote file to the local, deleting the remote file, modifying the local file, and uploading the modified local file to the server again.

In this embodiment, the cloud disk is mapped to a local disk through the Dokan file system, and users can easily browse, read and write files on the cloud disk through the local disk. The realization of the presentation of network files and online editing.
