In the following detailed description, the method for storing a file, the method for reading a file, and the electronic device according to the embodiments of the present invention will be described in detail in four aspects.
It should be understood that, in the embodiment of the present invention, the method for storing a file provided in the first aspect and the method for reading a file provided in the second aspect may be used in an electronic device simultaneously as a complement to each other, or may be used in an electronic device separately as an independent method; in a specific implementation process, the method for storing a file provided in the first aspect and the method for reading a file provided in the second aspect may be implemented by the same software or hardware, or may be implemented by different software or hardware; in addition, the electronic device provided in the third aspect and the electronic device provided in the fourth aspect may be the same electronic device or different electronic devices.
In a first aspect, please refer to fig. 2, an embodiment of the present invention provides a method for storing a file, where the method may be applied to an electronic device, that is, an execution subject of each step in the method may be the electronic device described above, and the electronic device may be connected to at least one network storage device in a network storage system. The process of the method is described as follows:
step 101: a business logic component in middleware of an electronic device obtains a first write operation request for storing a first file.
In the embodiment of the invention, the method for storing the file can be executed in the electronic equipment in a middleware mode. Specifically, the middleware includes a service logic component, and the service logic component can obtain a service requirement of a user, that is, a problem that the user wants to solve through a network storage device, for example, the service logic may be to store a certain movie to a certain network storage device, copy a picture from a certain path in a certain network storage device, create a folder in a root directory of a certain network storage device, and so on.
In the embodiment of the present invention, the first write operation request is used to instruct to store the first file, that is, to write data to the network storage device. The storing of the first file may be storing a packaged complete file such as a document, a picture, a compressed packet, or storing unpackaged data, or writing an instruction to be executed by the network storage device into the network storage device, or the like. For ease of understanding, in the subsequent description of the first aspect, the storage of "movie. mp 4" is illustrated as storing the first file.
In the embodiment of the present invention, there are various ways for the business logic component to obtain the first write operation request, for example, obtaining an instruction including the first write operation request through a calling interface provided by the middleware to a user; for another example, the middleware may provide a graphical user interface to the user, and the user may input the first write operation request by operating an icon on the user interface, such as dragging an icon of "movie. mp 4" to overlap with an icon of a certain network storage device in the user interface, which may indicate that "movie. mp 4" is stored in the network storage device.
Step 102: and the business logic component determines a first network storage device corresponding to the first network storage device identification from the at least one network storage device based on the first network storage device identification included in the first write operation request.
In the embodiment of the present invention, after obtaining the first write operation request in step 101, the service logic component abstracts the directly obtained first write operation request, that is, converts the problem that the user wants to solve through the first write operation request into a specific operation on the network storage device.
In step 102, the business logic component parses the first write operation request to obtain valid data included in the first write operation request for indicating execution of storing the first file. In this embodiment of the present invention, the first write operation request may include the first network storage device identifier. The first network storage device is a network storage device to which the user wants to store the first file, and the first network storage device identification may include identifications of one or more network storage devices, for example, when the user wants to store "movie. mp 4" to two network storage devices at the same time, the first network storage device identification may include identifications of the two network storage devices at the same time.
Specifically, the first network storage device identification may be a network address of the electronic device communicating with the first network storage device, or an identification code, a name, or the like of the first network storage device. In turn, the business logic component can determine the network storage device having the first network storage device identification as the first network storage device. In this embodiment of the present invention, the electronic device may further include a correspondence table between the network storage device identifier and the network storage device, and the network storage device corresponding to the first network storage device identifier may be determined as the first network storage device by querying the correspondence table, and the first network storage device may also be determined by querying an Address Resolution Protocol (ARP) table, and the like.
Step 103: a storage management component in the middleware mounts a first network storage device onto the electronic device.
In the embodiment of the present invention, the middleware may further include a storage management component, where the storage management component is configured to execute a specific operation on the network storage device. After abstracting the first write operation request in step 102 and determining the first network storage device according to the first network storage device identifier, the storage management component mounts the first network storage device onto the electronic device. By mounting the first network storage device, the electronic device can access the first network storage device and can operate the first network storage device and files and data stored in the first network storage device.
Step 104: the storage management component stores the first file in a first network storage device.
After the first network storage device is mounted in step 103, the first network storage device can be accessed in the electronic device, and the storage management component can store the first file in the first network storage device. For example, as exemplified in the foregoing description, the storage management component may store "movie. mp 4" in the first network storage device, and then the user may read and use "movie. mp 4" by accessing the first network storage device.
In a possible implementation manner, before the storage management component in the middleware mounts the first network storage device onto the electronic device in step 103, the method for storing the file may further include the following steps: the business logic component determines a first mounting mode corresponding to the first storage type based on the first storage type included in the first write operation request.
Furthermore, when the storage management component in the middleware mounts the first network storage device onto the electronic device in step 103, the storage management component may mount the first network storage device onto the electronic device in the first mounting manner, and may obtain a mounting path for accessing the first network storage device in the electronic device by mounting the first network storage device onto the electronic device.
In the embodiment of the present invention, a plurality of storage types for storing the first file may be included, for example, the storage types may include file-level storage, for example, a NAS storage manner, an FTP storage manner, and the like, and when the NAS storage manner is adopted, storage protocols such as NFS, CIFS, and the like may be used; as another example, the storage type may include data block storage, such as ISCSI storage, disk array storage, and the like.
In addition, in the embodiment of the present invention, before the first network storage device is mounted, it may be further determined in advance by the service logic component whether the first network storage device is mounted on the electronic device in the first mounting manner, and if the first network storage device is mounted in the first mounting manner, the mounting path of the first network storage device may be directly obtained without repeated mounting.
In a possible implementation manner, when the first storage type included in the first write operation request is file-level storage, the determining, by the business logic component, a first mount manner corresponding to the first storage type based on the first storage type included in the first write operation request may include: and the service logic component determines that the network mapping mode corresponding to the file level storage is a first mounting mode.
Furthermore, the mounting of the first network storage device onto the electronic device by the storage management component in the middleware may include: the storage management component mounts the first network storage device onto the electronic device in a network mapping mode to obtain a network address of the first network storage device as a mounting path.
In the embodiment of the present invention, each network storage device in the network storage system may have a unique network address, so that when the first network storage device is determined according to the first network storage device identifier in step 102, the network address of the first network storage device may be determined. Furthermore, when the first network storage device is mounted in a network mapping manner, the network address of the first network storage device can be obtained as a mounting path of the first network storage device.
For example, the network address of the first network storage device may be an IP address, and specifically for example, 192.168.1.233, the storage management component may obtain 192.168.1.233 a mount path for the first network storage device, and the user may access the first network storage device through the path of access 192.168.1.233. In addition, a path 192.168.1.233 can be replaced by a name easily recognized and called by a user in the electronic equipment, for example, 192.168.1.233 is replaced by a path Storage-1, when the user accesses the path Storage-1, the service logic component can automatically convert the path Storage-1 into a 192.168.1.233 path, and the first network Storage device is still accessed by the user finally.
When the storage type is file-level storage, the files can be managed more conveniently, and sharing of the files is facilitated.
In a possible implementation manner, when the first storage type included in the first write operation request is data block storage, the service logic component determines, based on the first storage type included in the first write operation request, a first mount manner corresponding to the first storage type, and may include the following steps: and the service logic component determines that the synchronous volume mounting mode corresponding to the data block storage is the first mounting mode.
Furthermore, the mounting of the first network storage device onto the electronic device by the storage management component in the middleware may include: the storage management component mounts the first network storage device to a preset path on the electronic device in a synchronous volume-mounting mode so as to obtain the preset path as a mounting path.
In the embodiment of the present invention, when the storage management component mounts the first network storage device in the synchronous volume mount manner, the storage management component may mount the first network storage device to a preset path in the electronic device, for example, the preset path may be a drive letter in the electronic device, such as "Z:" or "F:", or the preset path may also be a folder in the electronic device, such as "/dev/sda", or the like. Furthermore, when the first network storage device is mounted to the preset path in a synchronous volume mounting manner, the preset path can be obtained as the mounting path of the first network storage device. The user can directly access and manage the first network storage device mounted in the synchronous mounting mode through the mounting path, and the first network storage device is like accessing and managing a local disk mounted by the electronic device.
For example, the preset path may be "Z:", and the storage management component may obtain "Z:" as a mount path for the first network storage device, and the user may access the first network storage device by accessing "Z:".
In this embodiment of the present invention, after the step of mounting, by the storage management component, the first network storage device to the preset path on the electronic device in the synchronous volume mount manner, it may be further determined, by the service logic component, whether the first network storage device is successfully mounted to the preset path on the electronic device in the synchronous volume mount manner, and if it is determined that the first network storage device is not successfully mounted to the preset path on the electronic device in the synchronous volume mount manner, the service logic component may notify the user that the mounting is not successful, and may provide an option for the user to continue operating, where the following two possible options are provided in this embodiment of the present invention as examples:
the first method comprises the following steps: continuing to mount the first network storage device to a preset path on the electronic device in a synchronous volume mounting mode until the first network storage device is successfully mounted or the preset maximum repeated mounting times are reached;
and the second method comprises the following steps: and mounting the first network storage device on the electronic device in a network mapping mode, obtaining a network address of the first network storage device as a mounting path, and storing the first file in a file-level storage mode.
In addition, when the first network storage device is not successfully mounted to the preset path on the electronic device in the synchronous volume mounting manner, the middleware may also automatically select the possible options to perform operations according to actual situations.
When the storage type is data block storage, the storage speed is high.
In a possible implementation manner, the storing, by the storage management component in step 104, the storing the first file in the first network storage device may specifically include: the storage management component stores the first file in the first network storage device based on the mount path.
In the embodiment of the present invention, after the storage management component mounts the first network storage device onto the electronic device, the first network storage device can be accessed on the electronic device through the mount path, and therefore, the storage management component can also store the first file into the first network storage device according to the mount path. Specifically, when storing the first file in the first network storage device, the storage management component may store the first file directly to the mount path, or store the first file to a predetermined location under the mount path, for example, a subdirectory under the mount path, and so on.
When the first file is stored to the predetermined position under the mount path, the predetermined position may be included in the first write operation request or may be selected by the user after the mount is successful.
For example, assuming that the predetermined location is "\ new folder", the first file is "movie. mp 4", and the mount path is 192.168.1.233, the storage management component may store "movie. mp 4" under the path of "\ \192.168.1.233\ new folder", after which the user may access the path of "\ \192.168.1.233\ new folder \ movie. mp 4" to read the "movie. mp 4" file in the electronic device.
For another example, assuming that the predetermined location is "\ new folder", the first file is "movie. mp 4", and the mount path is "Z:", the storage management component may store "movie. mp 4" under the path of "Z: \ new folder", after which the user may access the path of "Z: \ new folder \ movie. mp 4" in the electronic device to read the "movie. mp 4" file.
The method for storing the file is illustrated by a specific implementation procedure. The middleware comprises a service logic component and a storage management component, wherein the storage management component can comprise an ISCSI management module, a NAS management module and a NAS tool module; the ISCSI management module and the NAS tool module correspond to data block storage in the embodiment of the invention, specifically, the ISCSI management module is responsible for connecting, logging in and hanging the network storage device through an ISCSI protocol, the NAS tool module is responsible for sharing, deleting and sharing the volume or the catalogue, and the like, and the ISCSI management module and the NAS tool module can be used for realizing the synchronous hanging of the network storage device; the NAS management module is responsible for mounting the network storage device as a local network disk in a network mapping manner through NAS protocols, such as the NAS protocols of NFS, CIFS, and the like. In addition, in the embodiment of the present invention, the middleware user may be a user, or may be software for calling a middleware service interface, or the like. The implementation process is as follows:
(1) a first write operation request is obtained by a business logic component from a middleware user to begin a mount operation. The first write operation request may be a complete operation instructing to store the first file to the first network storage device, or may be an operation instructing only to mount the first network storage device. The first write operation request may include the first network storage identifier, the storage type, an expected occupancy period/duration for storing the first file, and the like.
(2) And judging the storage type by the business logic component according to the first write operation request.
And (3.1) if the storage type judged in the step (2) is the local storage of the electronic equipment, for example, the storage type is stored in a local disk installed on the electronic equipment, the service logic component directly returns the judgment result to a middleware user, and the middleware user executes a first writing operation in a local storage mode, for example, stores a first file in a C disk in the local disk of the electronic equipment.
(3.2.1) if the storage type judged in the step (2) is file-level storage, calling the NAS management module by the service logic component, mounting the first network storage device to the electronic device in a network mapping manner by the NAS management module through an NAS protocol, and returning a mounting result to the service logic component by the NAS management module, wherein the mounting result comprises a mounting path of the first network storage device, namely a network address of the first network storage device.
And (3.2.2) the service logic component returns the mounting result to the middleware user.
(3.3.1) if the storage type judged in the step (2) is data block storage, the service logic component calls an ISCSI management module, the ISCSI management module adopts an ISCSI protocol to perform volume hanging operation on the first network storage device in a synchronous volume hanging mode, and the ISCSI management module returns a volume hanging result to the service logic component, wherein the volume hanging result comprises information used for indicating whether the first network storage device is hung and rolled up and volume information of the first network storage device.
And (3.3.2) the service logic component judges whether the first network storage is successfully hung according to the volume hanging result returned in the step (3.3.1).
(3.3.3.1) if the mount failure is determined in step (3.3.2), returning, by the business logic component, a message to the middleware user indicating the mount failure.
(3.3.3.2) if the mounting is determined to be successful in the step (3.3.2), the service logic component calls the NAS tool module, the NAS tool module shares the first network storage device with which the volume is successfully mounted, and allocates a preset path for the first network storage device, so as to finally mount the first network storage device to the preset path on the first network storage device. Furthermore, the NAS tool module returns a mount result to the service logic component, where the mount result includes a mount path of the first network storage device, that is, a preset path.
And (3.3.4) the service logic component returns the mounting result to the middleware user.

The method for storing the files provided by the embodiment of the invention adopts the design of the middleware framework to uniformly manage at least one network storage device connected with the electronic equipment, thereby greatly reducing the difficulty of using and managing the network storage device by a user.
Furthermore, in the embodiment of the present invention, the service logic and the storage management are separated, when the user uses the network storage device, only the interaction with the service logic component is needed, the service logic component abstracts the service logic of the user and converts the service logic into a specific operation on the network storage device, and the storage management component performs the specific operation and management on the network storage device. In the whole process of realizing the user service logic, the user does not need to specifically operate the network storage device, the operation difficulty of the user is reduced, and the network storage device can be conveniently used even for the user without network storage related professional knowledge.
Furthermore, in the embodiment of the present invention, the service logic and the storage management are separated by the middleware, so that a direct service call interface of the network storage device can be provided for a user, and the adaptability and the portability of the method for storing files in the embodiment of the present invention are improved.
In a second aspect, please refer to fig. 3, an embodiment of the present invention provides a method for reading a file, where the method may be applied to an electronic device, that is, an execution subject of each step in the method may be the electronic device described above, and the electronic device may be connected to at least one network storage device in a network storage system. The process of the method is described as follows:
step 201: a business logic component in middleware of an electronic device obtains a first read operation request for reading a first file.
In the embodiment of the invention, the method for reading the file can be executed in the electronic equipment in a middleware mode. Specifically, the middleware includes a service logic component, and the service logic component can acquire a service requirement of a user, that is, a problem that the user wants to solve through a network storage device, for example, reading a certain file, a folder, and the like in a certain network storage device.
In this embodiment of the present invention, the first read operation request is used to instruct to read the first file, that is, to read data from the network storage device. Reading the first file may refer to reading a packaged complete file such as a document, a picture, a compressed packet, or reading unpacked data, or the like. For ease of understanding, in the description that follows of the second aspect, the "movie. mp 4" stored in the first network storage device is illustrated as the first file.
In the embodiment of the present invention, there are various ways for the business logic component to obtain the first read operation request, for example, obtaining an instruction including the first read operation request through a calling interface provided by the middleware to a user; for another example, the middleware may provide a graphical user interface to the user, and the user may input the first read operation request by operating an icon on the user interface, such as double-clicking a "movie. mp 4" icon cached in the user interface, which may indicate opening a "movie. mp 4" file stored in the first network storage device.
Step 202: and the business logic component determines a first network storage device corresponding to the first network storage device identification from the at least one network storage device based on the first network storage device identification included in the first read operation request.
In the embodiment of the present invention, after the first read operation request is obtained in step 201, the service logic component abstracts the directly obtained first read operation request, that is, converts the problem that the user wants to solve by the first read operation request into a specific operation on the network storage device.
In step 202, the business logic component parses the first read operation request to obtain valid data included in the first read operation request for instructing to read the first file. In this embodiment of the present invention, the first read operation request may include a first network storage device identifier, and the first network storage device storing the first file may be determined from at least one network storage device included in the network storage system through the first network storage device identifier.
Specifically, the first network storage device identification may be a network address of the electronic device communicating with the first network storage device, or an identification code, a name, or the like of the first network storage device.
In the embodiment of the present invention, the electronic device may further include a correspondence table between the network storage device identifier and the network storage device, and by querying the correspondence table, it may be determined that the network storage device corresponding to the first network storage device identifier is the first network storage device, and in addition, the first network storage device may be determined by querying the ARP table, and so on.
Step 203: the business logic component determines a reading path of the first file based on a mount path of the electronic device for accessing the first network storage device and a storage path of the first file in the first network storage device.
In this embodiment of the present invention, the first read operation request may include a storage path of the first file in the first network storage device, where the storage path may indicate a location where the first file is specifically stored in the first network storage device. For example, if the storage path is "\ new folder \ movie. mp 4", it may indicate that the file "movie. mp 4" is stored in the "new folder" under the root directory of the first network storage device.
Furthermore, the service logic component can determine a read path of the first file according to the mount path of the first network storage device and the storage path of the first file.
For example, assuming that the storage path is "\ \ new folder \ movie. mp 4" and the mount path is 192.168.1.233, the business logic component may determine that the path of "\ \192.168.1.233\ new folder \ movie. mp 4" is a read path of the file of "movie. mp 4", and the user may access the path of "\ \192.168.1.233\ new folder \ movie. mp 4" in the electronic device to read the file of "movie. mp 4".
For another example, assuming that the storage path is "\\ new folder \ movie. mp 4" and the mount path is "Z:", the business logic component may determine that the path of "Z: \ new folder \ movie. mp 4" is a read path of the file of "movie. mp 4", and the user may access the path of "Z: \ new folder \ movie. mp 4" in the electronic device to read the file of "movie. mp 4".
Step 204: a storage management component in the middleware reads the first file based on the read path.
After the read path of the first file is determined in step 203, a specific read operation may be performed by the storage management component to read the first file from the read path.
In a possible implementation manner, before the business logic component determines the reading path of the first file, the method for reading the file may further include the following steps: the business logic component determines whether the first network storage device is mounted to the electronic device.
According to the determination result of the service logic component, if the first network storage device is not mounted on the electronic device, the storage management component mounts the first network storage device on the electronic device in a network mapping mode to obtain a network address of the first network storage device as a mounting path of the first network storage device.
For example, the network address of the first network storage device may be an IP address, specifically for example 192.168.1.233, and the storage management component may obtain 192.168.1.233 a mount path for the first network storage device. Furthermore, when the storage path of the first file is "\ \ new folder \ movie. mp 4", the storage management component may read the "movie. mp 4" file stored in the first network storage device from the path of "\ \192.168.1.233\ new folder \ movie. mp 4", with the file as the read object.
In the embodiment of the present invention, the determining, by the service logic component, whether the first network storage device is mounted on the electronic device may include determining, by the service logic component, whether the first network storage device is mounted on the electronic device in a network mapping manner or a synchronous volume mounting manner, may also include determining, by the service logic component, whether the first network storage device is mounted on the electronic device in a synchronous volume mounting manner, and may also include determining, by the service logic component, whether the first network storage device is mounted on the electronic device in a network mapping manner.
In a possible implementation manner, before the business logic component determines the reading path of the first file, the method for reading the file may further include the following steps: the business logic component determines whether the first network storage device is mounted to the electronic device.
According to the determination result of the service logic component, if the first network storage device is not mounted on the electronic device, the storage management component mounts the first network storage device to a preset path on the electronic device in a synchronous volume mounting mode so as to obtain a network address of the first network storage device as a mounting path.
In the embodiment of the present invention, because a synchronous volume hanging manner needs to consume a certain time, in order to be able to read the first file in time, when the service logic component determines that the first network storage device is not hung on the electronic device, the storage management component may simultaneously perform the following two operations:
operation one: and mounting the first network storage device on the electronic device in a network mapping manner to obtain that the network address of the first network storage device is a mounting path of the first network storage device, where the mounting path is used for the service logic module to determine a read path in step 203 of the file reading operation.
And operation II: and mounting the first network storage device to a preset path on the electronic device in a synchronous volume mounting mode.
In the embodiment of the present invention, when the storage management component successfully mounts the first network storage in a synchronous volume mount manner by executing the second operation, the storage management component may store mount information of the first network storage device, where the mount information may include a preset path on which the first network storage device is mounted. When the user needs to access the first network storage device again, the storage management component may directly obtain the preset path for mounting the first network storage device as the mounting path of the first network storage device according to the stored mounting information.
The method for reading the file is illustrated by a specific implementation procedure. The middleware comprises a service logic component and a storage management component, wherein the storage management component can comprise an ISCSI management module, a NAS management module and a NAS tool module; the ISCSI management module and the NAS tool module correspond to data block storage in the embodiment of the invention, specifically, the ISCSI management module is responsible for connecting, logging in and hanging the network storage device through an ISCSI protocol, the NAS tool module is responsible for sharing, deleting and sharing the volume or the catalogue, and the like, and the ISCSI management module and the NAS tool module can be used for realizing the synchronous hanging of the network storage device; the NAS management module is responsible for mounting the network storage device as a local network disk in a network mapping manner through NAS protocols, such as the NAS protocols of NFS, CIFS, and the like. In addition, in the embodiment of the present invention, the middleware user may be a user, or may be software for calling a middleware service interface, or the like. The implementation process is as follows:
(1) a first read operation request is obtained by the business logic component from a middleware user to begin read file path analysis. The first write operation request may be a complete operation instructing reading of the first file from the first network storage device, or may be an operation instructing only obtaining of the first file read path. The first read operation request comprises a first network storage device identification used for determining the first network storage device and a storage path of the first file in the first network storage device.
(2) And judging whether the first network storage device is mounted on the electronic device or not by the service logic component according to the first read operation request.

And (3.2.2) the service logic component determines a reading path of the first file based on the mounting path obtained in the step (3.2.1) and the storage path of the first file, and returns the reading path to the middleware user.
(3.2.3) while executing the step (3.2.2), the service logic component calls the ISCSI management module, the ISCSI management module adopts an ISCSI protocol, performs a volume hanging operation on the first network storage device in a synchronous volume hanging manner, and returns a volume hanging result to the service logic component, where the volume hanging result includes information indicating whether the first network storage device is successfully hung, and when the volume is successfully hung, the volume hanging result may also include volume information of the first network storage device.
And (3.2.4) the service logic component judges whether the first network storage device is successfully hung according to the volume hanging result returned in the step (3.2.3). If the service logic component determines that the volume hanging in the step (3.2.3) fails, the service logic component controls to repeatedly execute the step (3.2.3) until the volume hanging is successful or the preset maximum repeated volume hanging times is reached; and if the roll hanging work in the step (3.2.3) is determined, the business logic component stores the roll hanging result.
In the embodiment of the present invention, after the service logic component returns the read path to the middleware user, the middleware user can read the first file from the first network storage device through the read path. Also, in the event that a read path for the first file is determined, an operation to read the first file from the read path may be performed by the storage management component in accordance with the first read operation request.
In this embodiment of the present invention, the operation of determining, by the service logic component, whether the first network storage device is mounted to the electronic device may include determining, by the service logic component, whether the first network storage device is mounted to the electronic device in a network mapping manner or a synchronous volume mounting manner, may also include only determining, by the service logic component, whether the first network storage device is mounted to the electronic device in a synchronous volume mounting manner, and may also include only determining, by the service logic component, whether the first network storage device is mounted to the electronic device in a network mapping manner.
