Detailed Description
The present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Example one
Fig. 1 is a flowchart of a method for implementing a network disk drive identifier according to an embodiment of the present invention, where this embodiment is applicable to a situation where a client implements a mount of a network disk specific file on a local system virtual disk drive identifier, and the method can be executed by an implementation apparatus for a network disk drive identifier, and specifically includes the following steps:
In this embodiment, at the user's terminal, for example: the personal PC, the tablet or the mobile phone can be provided with a client, and the client can be suitable for various operating systems and can identify the operating system corresponding to the current terminal. And is responsible for communicating with the network disk system.
In this embodiment, the client may send a mount (mount) port query request to the network disk, and the network disk provides the mount port to the client. The client side can send a network disk mounting catalog request through the mounting port according to the received mounting port. The mount directory request may include: file directory path and file sharing protocol type. The file directory path may be a specific storage location provided by the network disk. And the network disk can conveniently acquire the corresponding file according to the file storage address.
And step 120, reading the folder corresponding to the file directory path from the storage system, and reading all files in the folder into a memory.
In this embodiment, since the file format adopted by the distributed storage system may not be consistent with the file sharing protocol type supported by the operating system corresponding to the client, and the purpose of mounting the disk identifier cannot be achieved, in this embodiment, the file corresponding to the file directory path is read from the storage system. And reading the file into the memory. After the files are read into the memory, the files corresponding to the file directory path can be decoupled from the limitation of the original storage relationship, so that the corresponding folders can be mounted by using the disk identifiers conveniently.
And step 130, returning a handle corresponding to the folder to the client, so that the client associates the handle label with the created virtual drive.
A Handle (Handle) is an identifier used to identify an object or item. Since the address of the data needs to be changed and the change needs to be recorded and managed after the change, the change of the data address can be described by a handle. Therefore, in this embodiment, the handle may be used as an identifier, so as to associate the user drive letter with the corresponding file memory address. The network disk can determine the handle of the file by reading the memory and send the handle to the client.
The client may create one or more virtual drives in advance in the user's terminal. The method can be implemented by adopting the existing mode, and is not described in detail herein. After the virtual drive is created, a handle may be associated with the created virtual drive. Corresponding to the address in the network disk memory. The mounting of the network disk appointed directory on the user terminal disk identifier is realized.
In this embodiment, a mount port is provided for a client, and a network disk mount directory request is received from the mount port, where the mount directory request includes: a file directory path; reading a file corresponding to the file directory path from a storage system, and reading the file into an internal memory; and returning a handle corresponding to the file to a client so that the client associates the handle label with the created virtual drive letter. The files stored in the distributed storage system are separated from the original storage format, and the folder designated by the user in the network disk can be mounted as the local virtual disk identifier of the user. The network disk system does not need to process the files stored in the distributed storage system aiming at different file sharing protocols supported by the client, so that the consumption of network disk resources is reduced.
In a preferred embodiment of this embodiment, before providing the mount port to the client, the method may further add the following steps: and receiving a file system connection request sent by a client through a file service port, and providing network file service corresponding to the service port for the client. Before providing a mount port for a client, the client needs to send a file system connection request through a file service port, and when the network disk system judges whether the request is a legal request or not, and when the request is determined to be the legal request, the network disk system provides corresponding network file service for the client, so that a malicious network disk mount request is prevented.
In another preferred implementation manner of this embodiment, before receiving a file system connection request sent by a client through a file service port, the method may further add the following steps: receiving a port mapping request sent by a client, determining a corresponding file service port number according to a file sharing protocol type in the port mapping request, and sending the file service port number to the client. Because the types of the file sharing protocols corresponding to the terminals corresponding to the clients are different, the network disk server needs to set a corresponding network port for the file sharing protocol adopted in each client. When the client proposes the network file service, the client should acquire the network file service port corresponding to the network disk server in advance. Optionally, the client may send a port mapping request to the network disk first, and the network disk receives the port mapping request, determines a corresponding service port number according to a file sharing protocol type included in the port mapping request, and sends the service port number to the client. And records the corresponding file sharing protocol. So that the client can send the network file service request according to the corresponding port number, and the network disk can provide corresponding file service for mounting the network disk according to the network file sharing protocol.

Correspondingly, the method for implementing the network disk drive provided by the embodiment specifically includes:
And step 230, returning a handle corresponding to the folder to the client, so that the client associates the handle label with the created virtual drive.
After the network disk and the virtual disk signature of the terminal are mounted, the user can operate the network disk file through the operation of the virtual disk signature. In this embodiment, the user can view the attribute of the file through the right key operation in the mounted virtual drive.
For example, the attribute checking operation may be consistent with the attribute checking operation of a conventional local hard disk, and after receiving a file checking operation of a user, a client may send an attribute checking request to a network disk, and since corresponding content of a folder has been read into a memory, when sending the checking request, the attribute checking request does not refer to a specific folder, but corresponds to a corresponding storage address in the memory, and therefore, the attribute checking request includes: and the handle corresponds to the file. The network disk finds out the corresponding memory address according to the handle, and correspondingly reads out the attribute of the file, such as the basic attribute information of the size and the space utilization rate. In addition, management attribute information of the user, the group and the authority of the corresponding file can be searched through a network disk system.
And step 250, acquiring the attribute information of the file from the memory according to the handle.
