Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a commodity or system comprising such elements.

In addition, the sequence of steps in the method embodiments described below is only an example and is not strictly limited.

FIG. 1 is a schematic diagram illustrating a file storage process of a file processing system according to an embodiment of the present invention, where, as shown in FIG. 1, the file processing system includes: client, storage device, storage management server. The client and the storage device are both located in the same local area network, and the storage management server is located at the server.

In practice, the client may be some sort of instant messaging application, some sort of client providing data storage functionality, etc. The storage device herein refers broadly to an electronic device with a storage function, and may be a PC, a server, a notebook, or the like. The storage management server is a server for managing storage devices, and may be a service deployed in a certain device in the cloud.

The storage management server and the business server are located at the server, which should be understood to be located at the remote end or the cloud end, and refer to that they are not located in the same lan with respect to the client.

The meaning of "client and storage device both within the same local area network" in this context is described below by taking a client as an example of some instant messaging application:

Assuming that a company builds up its own wireless lan, electronic devices with storage functions in the company can all be used as storage devices in the document, and these storage devices all access the wireless lan. In addition, it is assumed that some instant messaging application program is installed in the terminal devices of the staff in the company, and the staff in the company can connect the terminal devices of the staff in the company to the wireless local area network, so that the instant messaging application program and the storage device corresponding to each staff are located in the same local area network.

That is, the client is located in a local area network, and the terminal device of a user installed with the client is located in a local area network, which is only used for descriptive purposes.

Taking a client as an example of an instant messaging application, a staff a in an enterprise may send a file to another staff b through the instant messaging application, or staff a may send a file to a work group. In this scenario, the file processing system provided in this embodiment may be used to store the file on the local area network side of the enterprise, that is, to store the file in a certain storage device in the local area network. The file is stored in the local area network because the transmission efficiency of the file in the local area network is much higher than that in the public network, for example, the downloading speed of the file from the local area network by staff b is much faster than that of the file from the server.

Based on this, in the storing process of the file, the functions of the respective constituent elements in the file processing system shown in fig. 1 are summarized as follows:

the client is used for responding to the file sending operation and sending first application information to the storage management server, wherein the first application information comprises a local area network identifier corresponding to the client; receiving storage configuration information sent by a storage management server, wherein the storage configuration information comprises a first file identifier and an address of storage equipment, which are distributed by the storage management server; and storing the file and the first file identification into the storage device according to the address of the storage device.

The storage management server is used for selecting the storage device from the storage device set corresponding to the local area network identifier, distributing the first file identifier, sending the first file identifier and the address of the storage device to the client, and sending the first file identifier to the storage device.

For better visual understanding of the operation of the file processing system, as shown in fig. 1, the file storage process may include the following steps:

100. The storage device sends registration information to the storage management server, wherein the registration information comprises the address of the storage device and the corresponding local area network identifier.

In the embodiment of the invention, to realize the storage of the file in the local area network of the user, one precondition is that: the local area network has registered storage devices that can be used for file storage. Therefore, the storage devices in a local area network need to register with the storage management server.

Taking an enterprise as an example, an administrator within the enterprise may access a storage management server to perform registration of storage devices within the enterprise. For example, the administrator may fill in the registration interface with an address (such as an IP address and a MAC address) of at least one storage device and a lan identifier corresponding to the enterprise, where the lan identifier may be a network name and a network address of the lan, and in some scenarios, the lan identifier may also be an enterprise name.

The administrator in the enterprise accesses the storage management server through each storage device to be registered, so that the management device can automatically fill in the own IP address at the corresponding position in the registration interface, and the administrator can also manually input the IP address. At this time, each storage device sends registration information including its own address and the corresponding lan identifier to the storage management server based on the operation of the administrator.

Of course, the administrator in the enterprise may access the storage management server through any device, and the administrator may also write the addresses and the lan identifiers of all the storage devices to be registered into the corresponding locations in the registration interface displayed by the storage management server, so as to form the registration information of these storage devices.

After receiving the registration information of each storage device, the storage management server stores the correspondence between the local area network identifier and the address of each storage device.

In addition, the registration information of the storage device may further include available storage space information of the storage device, such as what storage capacity and storage locations (or storage paths) may be provided by a certain storage device for storing files, where the available storage space information may be set by an administrator.

101. And responding to the file sending operation, and sending the local area network identification corresponding to the client to the storage management server by the client.

For convenience of description, the client is denoted as App, and when the client is installed in the terminal device of the user a, the client corresponding to the user a is denoted as App-a, and similarly, the client corresponding to the user B is denoted as App-B. Assuming that the client is an instant messaging application program, in a scenario that the user a sends a file to the user B through App-a, the file sending operation is an operation that the user a loads the file into a chat window with the user B.

At this time, based on the file sending operation of the user a, the client (i.e., the client installed in the terminal device of the user a: app-a) sends first application information to the storage management server, where the first application information includes the lan identifier corresponding to App-a, that is, the identifier of the lan where the terminal device of App-a is currently installed.

Optionally, the first application information may further include file size information of a file to be stored, so that the storage management server may select a storage device that meets the file size later.

The first application information is used for applying for the storage equipment for storing the file to the storage management server side.

102. The storage management server selects storage equipment from a storage equipment set corresponding to the local area network identifier, and distributes a first file identifier.

103. And the storage management server side sends the first file identification and the address of the selected storage device to the client side.

104. And the storage management server side sends the first file identification to the selected storage device.

As stated in step 100, an administrator may register one or more storage devices in a local area network with a storage management server, so that the storage device set in step 102 is made up of the storage devices registered in the local area network. The storage device set includes the address of each storage device, and may even further include the available storage space information of each storage device.

Optionally, when the first application information includes file size information, the storage management server selects a storage device that satisfies the file size information from the storage device set. For convenience of description, the selected storage device is referred to as a target storage device.

Of course, when there are a plurality of storage devices satisfying the file size information, the storage management server may further select an optimal storage device from among the storage devices as a target storage device in combination with factors such as bandwidth and load of the storage device.

When the storage management server selects the target storage device, a first file identifier is further allocated for the current file storage behavior of the App-A, further storage configuration information containing the first file identifier and the address of the target storage device is sent to the App-A, and meanwhile, the first file identifier is sent to the target storage device.

The first file identifier is a storage index of a file sent by the user A through the App-A in the target storage device. In addition, the first file identifier can also be used for the follow-up target storage device to carry out validity authentication on the file storage behavior of the App-A.

105. And the client sends a file storage request to the storage device according to the received address of the storage device, wherein the file storage request comprises a file and a first file identifier.

106. The storage device discovers that the first file identifier in the file storage request is consistent with the first file identifier sent to the storage management server side, and stores the first file identifier and the file.

After receiving the first file identification and the address of the target storage device sent by the storage management server, the App-A sends the file to be stored and the first file identification to the target storage device according to the address of the target storage device. And if the target storage device finds that the first file identifier sent by the App-A is consistent with the file identifier received by the target storage device from the storage management server, the target storage device indicates that the current file storage behavior of the App-A is effective, and the file sent by the App-A is stored locally corresponding to the first file identifier.

Based on the method, the storage of the file sent by the user A through the client in the local area network where the user A is located is realized. Thus, when the user B in the same local area network needs to download the file, the user B only needs to download the file from the storage device storing the file in the local area network through the client App-B. Compared with the storage of the file at the server through the public network, the file transmission efficiency is higher.

Fig. 2 is a schematic diagram of another file storage process of the file processing system according to the embodiment of the present invention, where, as shown in fig. 2, the file processing system may include, in addition to the client, the storage device, and the storage management server shown in fig. 1, a service server corresponding to the client, where the service server is located at the server, that is, located at the cloud.

Therefore, in the file storage process, the client is further used for responding to the file sending operation, uploading the file to the service server for storage, and obtaining a second file identifier distributed by the service server for the file. The business server is used for storing the file and distributing a second file identifier.

For better visual understanding of the working process of the file processing system in this embodiment, as shown in fig. 2, the storing process of the file may include the following steps:

201. the client receives file sending operation triggered by a user.

202. And the client uploads the file to the business server for storage.

203. And the business server side stores the file and distributes a second file identifier for the file.

204. And the business server side sends the second file identification to the client side.

205. The client sends first application information to the storage management server, wherein the first application information comprises a local area network identifier and a second file identifier corresponding to the client.

206. The storage management server selects a storage device from the storage device set corresponding to the local area network identifier, and allocates a first file identifier.

207. And the storage management server side sends the first file identification and the address of the selected storage device to the client side.

208. And the storage management server side sends the first file identification to the selected storage device.

209. And the client sends a file storage request to the storage device according to the received address of the storage device, wherein the file storage request comprises a file and a first file identifier.

210. The storage device discovers that the first file identifier in the file storage request is consistent with the first file identifier sent to the storage management server side, and stores the first file identifier and the file.

The registration process of the storage device is omitted in this embodiment.

The scenario in which user a sends a file to user B through client App-a is still described in the foregoing as an example. In this embodiment, based on the triggering of the user a, app-a stores the file in a storage device in the local area network where the user a and the user B are located on the one hand, and stores the file in the service server on the other hand. The data is stored in the service server, on the one hand, because in some practical application scenarios, security and other considerations may be taken into account, authentication needs to be performed on the file storage behavior of the user a, and at this time, the service server needs to execute authentication processing logic. On the other hand, when no storage device exists in the local area network or the storage device storing a certain file fails, the file stored in the service server can be used as a spam scheme to ensure that the user B can download and obtain the file.

For example, the authentication processing logic of the business server to the file storage behavior of the client may be: whether the user A has the authority to send the file to the user B, whether the file size meets the requirement, whether the file type is allowed, and the like are judged. If the file storage behavior of the user A passes the authentication, the service server allocates a second file identifier for the file, stores the file and the second file identifier, and feeds back the second file identifier to the App-A. Similar to the first file identifier, the second file identifier may be used as a storage index of the file at the service end.

According to the above process, the storage management server may store the correspondence between the first file identifier, the second file identifier and the target storage device, where the target storage device is the storage device selected by the storage management server and used for storing the first file identifier and the file. This correspondence may be used in the process of downloading the file by user B, as will be described in the following embodiments.

In order to ensure the storage security of the file, in the process of storing the file in the storage device, some security protection mechanisms are further provided in the embodiment of the present invention, which is described below in conjunction with fig. 3.

Fig. 3 is a schematic diagram of a file storage process of a file processing system according to an embodiment of the present invention, and fig. 3 is taken as an example of a file processing system including a client, a storage device, and a storage management server shown in fig. 1, and it is understood that the solution of this embodiment is also applicable when the file processing system further includes a service server as shown in fig. 2. As shown in fig. 3, the storing process of the file may include the steps of:

301. and the client responds to the file sending operation and sends the local area network identifier corresponding to the client to the storage management server.

302. The storage management server selects storage equipment from a storage equipment set corresponding to the local area network identifier, and distributes a first file identifier, first authentication information and a secret key.

The selected storage device may be referred to as a target storage device.

The first authentication information may be, for example, a storage task identifier and/or token (token) allocated by the storage management server for the current file storage behavior of the client.

The token has a set life cycle, such as 1 minute. The storage task identification may be a randomly generated string of characters or numbers. The key may be generated by the storage management server based on a set key generation algorithm.

The key is used for encrypting and protecting the file. The first authentication information is used for verifying the validity of the file storage behavior of the client.

303. And the storage management server side sends the first file identification, the address of the selected storage device, the first authentication information and the secret key to the client side.

304. And the storage management server side sends the first file identification and the first authentication information to the selected storage device.

305. And the client sends a file storage request to the storage device according to the received address of the storage device, wherein the file storage request comprises the file encrypted by the key, a first file identifier and first authentication information.

306. The storage device discovers that the first file identification and the first authentication information in the file storage request are matched with the first file identification and the first authentication information received by the storage device from the storage management server, and then the first file identification and the file are stored.

Taking the storage task identifier and the token as examples, if the storage device finds that the first file identifier and the storage task identifier carried in the file storage request sent by the client are consistent with the first file identifier and the storage task identifier received by the storage management server, the token carried in the file storage request is consistent with the token received by the storage management server, and the token does not exceed the set life cycle, the file storage request is considered to be valid, and the first file identifier and the encrypted file are stored.

It is to be understood that, here, the first file identifier and the first authentication information are corresponding, and the correspondence refers to: assuming that the storage management server allocates corresponding file identifiers and authentication information for two file storage behaviors (usually corresponding to two different files) successively, for example, allocates a file identifier a and authentication information a for the storage behavior of the file 1, allocates a file identifier b and authentication information b for the storage behavior of the file 2, and the storage devices corresponding to the two files are both devices T, the device T will receive the file identifier a and authentication information a corresponding to the storage behavior of the file 1, and the file identifier b and authentication information b corresponding to the storage behavior of the file 2. At this time, if the file storage request sent by a certain client includes the file identification a and the authentication information b, the file storage request will not pass the authentication even if the file identification a and the authentication information b are stored in the storage device T, since the file identification a and the authentication information b do not have a correspondence relationship.

307. The storage device sends a file storage success notification to the client.

308. The client generates CRC corresponding to the file.

Wherein, cyclic redundancy check code (Cyclic Redundancy Check, CRC for short).

309. The client sends the CRC to the storage management server.

It should be noted that the execution of steps 307-309 is not limited to this embodiment, as is equally applicable in the embodiments shown in fig. 1 or fig. 2.

Based on the above process, the file is encrypted by the key, so that the security of the file in the transmission process is ensured; and through the authentication of the first authentication information, the validity of the file storage behavior executed by the client to the storage device is ensured.

According to the above process, the final storage management server may store the corresponding relationship among the first file identifier, the second file identifier, the target storage device, the key and the CRC, where the target storage device is the storage device selected by the storage management server and used for storing the first file identifier and the file. The correspondence may be used in the downloading process of the file, which will be described in the following embodiments.

In one or more embodiments, it is mentioned that, based on the triggering of the file storage behavior of the client, the storage management server selects a storage device from the storage devices included in the corresponding local area network, so that the client stores the file to be stored in the storage device.

Assuming that the selected storage device is referred to as a target storage device, optionally, as described above, the storage management server may select an optimal storage device from among the storage devices as the target storage device based on the file size, bandwidth, load, and the like.

Alternatively, however, the storage management server may select the target storage device according to a probing process as illustrated in fig. 4 below.

Fig. 4 is a schematic diagram of a further file storage process of the file processing system according to the embodiment of the present invention, and fig. 4 is taken as an example for describing that the file processing system includes the client, the storage device, and the storage management server shown in fig. 1, and it can be understood that the solution of this embodiment is also applicable when the file processing system further includes the service server shown in fig. 2. As shown in fig. 4, the storing process of the file may include the steps of:

401. and the client responds to the file sending operation and sends the local area network identifier corresponding to the client to the storage management server.

402. And the storage management server side sends the storage equipment set corresponding to the local area network identifier to the client side.

403. And the client sends a detection request to each storage device according to the address of each storage device in the storage device set.

Wherein the probe request is used to probe whether each storage device is available. The probe request may be, for example, a ping command to probe whether the memory device is capable of ping.

404. And the client determines available storage equipment of the client according to detection results respectively corresponding to the storage equipment.

If the client is able to receive a probe response sent by a certain storage device in response to a probe request, this indicates that the storage device is available, and conversely, if no probe response fed back by the certain storage device is received, this indicates that the storage device is not available.

Because a certain storage device in the local area network may fail for some reasons, so that the storage device cannot be used by the client at present, through the detection process, it can be ensured that the target storage device selected by the storage management server is a storage device which can be used by the client which triggers the file storage behavior at present, so as to ensure reliable storage of the file in the local area network.

405. The client sends the available storage equipment to the storage management server.

406. The storage management server selects a storage device from the available storage devices and allocates a first file identifier.

407. And the storage management server side sends the first file identification and the address of the selected storage device to the client side.

408. And the storage management server side sends the first file identification to the selected storage device.

409. And the client sends a file storage request to the storage device according to the received address of the storage device, wherein the file storage request comprises a file and a first file identifier.

410. The storage device discovers that the first file identifier in the file storage request is consistent with the first file identifier sent to the storage management server side, and stores the first file identifier and the file.

The above describes the implementation of the file storage process in the above-described file processing system by several embodiments, and the following describes the implementation of the file download process in connection with the following several embodiments.

It should be noted that, first, the scenario that the user a sends the file to the user B through App-a is accepted in the foregoing, the user downloading the file may be either user a or user B, that is, user a may download the file through App-a, or user B may download the file through App-B, so that the client in the downloading process of the file described below may be either App-a or App-B in the scenario. Whether App-a or App-B, is a representation of the same client App attached with different user attributes.

In the scenario where user a sends a file to user B, the file download process is described below taking the more general case of user B downloading the file as an example.

Fig. 5 is a schematic diagram of a file downloading process of the file processing system according to an embodiment of the present invention, where, as shown in fig. 5, the file downloading process may include the following steps:

501. the client responds to the file downloading operation aiming at a certain file and sends second application information to the storage management server, wherein the second application information comprises a second file identifier corresponding to the file and a local area network identifier corresponding to the client.

Based on the file sending operation of the user A to the user B, prompt information of the file can be displayed in the App-B of the user B, for example, when the client is an instant messaging application program, the user A sends a file in a chat window with the user B, and the user B can see the file in the chat window so as to execute file downloading operation on the file.

In the scenario where the user a sends a file to the user B, when the file sent by the user a is also stored in the service server illustrated in fig. 2, the file has a file identifier corresponding to the file stored in the service server, that is, the aforementioned second file identifier.

Therefore, the App-B can send second application information carrying the second file identification and the local area network identification corresponding to the App-B to the storage management server based on the file downloading operation triggered by the user B.

In fact, the user A and the user B are in the same local area network at this time, namely, the terminal equipment where the App-A is located and the terminal equipment where the App-B is located are accessed into the same local area network at this time.

In this embodiment, the second application information is used to apply to the storage management server for the configuration information required for downloading the file, which may be referred to as downloading configuration information.

502. The storage management server determines that a first file identifier corresponding to the second file identifier exists.

503. The storage management server side sends the first file identification and the address of the storage device storing the first file identification to the client side.

After receiving the second application information, the storage management server first inquires whether a first file identifier corresponding to a second file identifier in the second application information exists locally, where the first file identifier is a file identifier corresponding to the file when the file is stored in the target storage device, as described above. If there is a first file identification corresponding to the second file identification, it is stated that the file was previously stored in a certain storage device in the local area network, from which storage device the user B can download the file. Then, the storage management server determines the storage device storing the first file identifier, namely the file, as the target storage device in the previous description.

As described above, the storage management server may maintain the correspondence between the first file identifier, the second file identifier, and the target storage device, and thus, the storage management server may determine whether the first file identifier corresponding to the second file identifier exists and the target storage device storing the first file identifier based on the correspondence.

After the first file identifier and the target storage device are obtained through inquiry, the download configuration information containing the first file identifier and the address of the target storage device can be sent to the client, namely the App-B, so that the App-B can download the file corresponding to the first file identifier from the target storage device according to the address of the target storage device.

504. And the client downloads the corresponding file from the storage device according to the address of the storage device and the first file identifier.

In this embodiment, for the file downloader, since the file is stored in the storage device in the local area network, the downloader can quickly download the required file from the storage device in the local area network, thereby improving the downloading efficiency of the file.

In addition, it should be noted that, if the storage management server finds that the first file identifier corresponding to the second file identifier does not exist locally after receiving the second application information sent by the client, it indicates that the file to be downloaded is not stored in a storage device in the local area network corresponding to the client, and at this time, the storage management server may feed back error prompt information to the client, so that when the client cannot successfully download the file from the storage device, the client downloads the file from the service server according to the second file identifier.

In the file storage process, it is mentioned that some security protection mechanisms are provided to ensure the storage security of the file, and accordingly, some security protection mechanisms may also be provided in the file downloading process to avoid malicious downloading of the file, which is described below in connection with fig. 6.

Fig. 6 is a schematic diagram of another file downloading process of the file processing system according to the embodiment of the present invention, and as shown in fig. 6, the file downloading process may include the following steps:

601. the client responds to the file downloading operation aiming at a certain file and sends second application information to the storage management server, wherein the second application information comprises a second file identifier corresponding to the file and a local area network identifier corresponding to the client.

602. And if the storage management server determines that the first file identifier corresponding to the second file identifier exists, the storage management server sends an authentication instruction to the service server.

603. And the business server authenticates whether the user corresponding to the client has the downloading authority of the file.

604. And if the authentication is passed, the service server side sends an authentication passing notification to the storage management server side.

In this embodiment, the service server may also verify the file downloading behavior of the user B to verify whether the user B has the file downloading authority, similar to the verification that the service server may verify the file storing behavior of the user a in the file storing process.

For example, it is verified whether the file is sent to the user B, whether the terminal device corresponding to the user B performing the downloading operation meets the requirement, and so on.

It should be noted that if the storage management server does not find that the first file identifier corresponding to the second file identifier is locally stored, the error prompt information may be fed back to the client, and at this time, the client may download the corresponding file from the service server according to the second file identifier, and in the downloading process, the service server may also perform the authentication process described above.

605. The storage management server determines the address of the storage device storing the first file identifier and distributes second authentication information corresponding to the file downloading behavior.

Similar to the file storage process, the download task identification and/or token may be included in the second authentication information. The download task identification is used to identify a download process. Tokens have certain lifecycle limitations.

606. The storage management server side sends the address of the storage device, the first file identification, the second authentication information, CRC and the key corresponding to the first file identification to the client side.

As described above, based on the execution result of the file storage process, the storage management server may maintain the correspondence between the first file identifier, the second file identifier, the key required to encrypt the file, the CRC of the file, and the address of the target storage device storing the file and the first file identifier. Thus, based on the correspondence, the storage management server can obtain the CRC, the key, and the address of the target storage device.

607. And the storage management server side sends the first file identification and the second authentication information to the storage equipment.

608. And the client sends a file downloading request to the storage device according to the address of the storage device, wherein the file downloading request comprises a first file identifier and second authentication information.

609. The storage device determines whether the file downloading request is effective according to the first file identifier and the second authentication information received from the storage management server, and obtains an encrypted file corresponding to the first file identifier when the file downloading request is effective.

The process of verifying the file downloading behavior triggered by the user B according to the second authentication information is similar to the process of verifying the file storing behavior of the user a according to the first authentication information, which is not described herein.

610. The storage device sends the encrypted file to the client.

611. The client decrypts the encrypted file according to the received key to obtain the required file.

612. And the client performs CRC verification on the obtained file according to the received CRC.

The process of CRC validation may be: the client calculates the file obtained by decryption to obtain a corresponding CRC, and the corresponding CRC is assumed to be a first CRC; the CRC corresponding to the first file identification received by the client from the storage management server is called a second CRC; comparing whether the first CRC is consistent with the second CRC, if so, determining that the decrypted file is the file sent by the user A, and if not, determining that the file is possibly tampered, and considering that the file is failed to be downloaded. If the file downloading fails, the client can also download the corresponding file from the service server according to the second file identifier.

In this embodiment, for the file downloader, since the files are simultaneously stored in the storage device in the local area network and in the service server of the server, the downloader can preferentially and rapidly download and obtain the required files from the storage device in the local area network, so as to improve the downloading efficiency of the files, but when the files cannot be successfully downloaded from the local area network, the files can also be downloaded from the service server, thereby ensuring that the files can be successfully downloaded.
