Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the invention belong. The terms (such as those defined in commonly used dictionaries) will be interpreted as having a meaning that is the same as the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in connection with the various embodiments of the invention.
The technical scheme of the application is applied to an application scene that a client performs file processing on data stored in a cloud, and provides a decentralizing file management system.
The technical scheme of the application is described in the following specific embodiments.
Example 1
As shown in fig. 1, the de-centralized file management system of the present application includes a cloud server 100, a client 200, and a plurality of network terminal devices (IPCs) 300.
The client 200 is configured to send a file management request to the cloud server 100.
The client 200 is an electronic device used for interaction between a user and the cloud server 100, such as a mobile phone, a computer, a tablet, etc., and the user can interact with the cloud server 100 through a network of the electronic device, and the file management request is a data packet sent by the user for managing a file on the cloud, which may be a network request data packet of an HTTP request, etc.
The file management request includes authentication information and target device information, where the target device information is UUID and port information of the network terminal devices, and the UUID is ID data corresponding to the network terminal devices one by one, and is used to uniquely identify the network terminal devices 300. This information is used to ensure access legitimacy and is used by the cloud server to route to the correct target network termination device.
By adding the UUID into the file management request, the device needing to be subjected to file management can be named, in addition, when the UUID of the device where the file needing to be subjected to file management is not known, a search request can be initiated first, the request is one of the file management requests, then the corresponding search instruction is sent, and the search requirement of a user is executed through the search instruction.
The cloud server 100 receives the file management request sent from the client 200, authenticates the file management request, and sends the authenticated file management request to the corresponding network terminal device 300 through the corresponding link.
In this embodiment, there is a stable long connection between the cloud server 100 and each network terminal device 300, where the long connection may be a long connection established based on a TCP protocol, or a stable long connection established based on a private protocol of another intranet, where the long connection is established by the cloud server 100 actively when the network terminal device 300 is online. The long connection is divided into a data connection and an instruction connection, the data connection is used for transmitting data, such as file management request and feedback data of feedback, and the instruction connection is used for transmitting data, such as instructions or heartbeat packets.
After receiving the file management request, the network terminal device 300 executes the file management operation in the file management request, and feeds back response data to the cloud server.
The network terminal device 300 may be a plurality of network devices such as network cameras arranged in a network, and the application has the capability of acquiring data, and a file management system is loaded in the network terminal device to execute file management operation.
Authentication is to identify the authority of the file management request, determine whether the request is legal, and implement authentication by means of a secret key or signature verification, and after the authentication is successful, the file management request needs to be executed, for the cloud server 100, it is not required to execute specific file management operations in the file management request by itself, and in the system of this embodiment, these operations are all executed by the network terminal device 300 in the network, so the cloud server 100 forwards the file management request according to the UUID in the file management request.
Particularly, if the file management request is to execute the search instruction, the cloud server 100 will send the search instruction to each network terminal device 300 through all instruction links, and after the network terminal device 300 operates according to the search instruction, the corresponding response data is returned to the cloud server, so as to implement the search operation.
And the cloud server sends the response data to the client.
After receiving the response data, the cloud server 100 feeds back the response data to the corresponding client, thereby completing the remote file management operation.
In addition, when the client and the network terminal device are in the same network environment, such as in the same lan, the client may communicate directly with the network terminal device, i.e. directly. At this time, the client can directly send the file management request to the target network terminal device, and the file management request itself carries authentication information, so that the direct communication mode can also enable the network terminal device to perform corresponding response operation. So that the whole system can be more flexible.
The decentralized file management system of the embodiment mainly transfers file management operations to the network terminal equipment, the cloud server only plays a role in forwarding, stable long connection is established between each network terminal equipment and the cloud server, and the cloud server realizes information interaction with each network terminal equipment through the long connection, so that a user can remotely control the network terminal equipment to perform corresponding file management operations.
Example 2
As shown in fig. 2, the method for managing a file in a decentralization manner according to the present embodiment includes:
step S100, a file management request is sent to a cloud server.
In order to better explain the technical scheme of the present application, as shown in fig. 3, an interaction diagram is shown when the present application performs the decentralized file management procedure.
And sending a file management request from the client to the cloud server, wherein the file management request can be a common request packet of some communication protocols, and carrying corresponding data in the packet to perform file management processing.
For example, a user can communicate with the cloud server on a webpage of the client, and then can use a common HTTP communication protocol to perform corresponding communication, and for the user, no matter whether the user uses an IE browser or an APP interface to perform communication operation, the user actually communicates through the webpage, so that an HTTP communication protocol can also be used to generate an HTTP request packet as a file management request, and the HTTP request packet is sent to the cloud server.
Wherein the file management operations actually performed for the user are different, and the file management requests include different data.
For example, the user performs the operation of deleting, calling and searching the file in a certain network terminal device, and the file management request may include related parameters such as UUID, port number and the like of the target network terminal device, and a corresponding management operation.
If the user does not know where the file is, only knows some characteristics of the file, the user can perform a search operation, and the file management request sent at this time contains a corresponding search instruction, so as to perform the search operation on the required file.
And a connection needs to be established between the client and the cloud server to support the request sending and the subsequent data returning, so that a stable connection, such as a TCP connection, exists between the cloud server and the client.
In addition, it should be noted that, if the client and the target network terminal device are in the same network environment, such as a lan, the client may directly communicate with the network terminal device, that is, directly connect. At this time, the client may directly transmit the file management request to the target network terminal device.
Step 200, receiving a file management request sent by the client, authenticating the file management request, and sending the authenticated file management request to the corresponding network terminal equipment through the corresponding link.
After receiving the file management request, the cloud server performs authentication operation, and the request after authentication success is sent to the network terminal equipment.
The authentication may be implemented by a middleware, for example, the middleware is configured to determine a request type, extract request header information, determine whether a request is legal, determine whether a device and a service to be accessed by the client exist, and so on, so as to determine the request and the validity in advance.
The cloud server and each network terminal device conduct information interaction through a link formed by long connection.
When the network terminal equipment is started up and is on line, connection is actively established with the cloud server to form stable long connection, the long connection comprises a data link and an instruction link, and different links transmit different kinds of data.
The cloud server manages the links through the cloud link service, because the network terminal devices are numerous, the links correspondingly have a plurality of links, the collection of the storage links is a link pool, and when the cloud server needs to forward the file management request, the cloud server searches the corresponding links through the cloud link service to forward the file management request.
If the request includes related parameters such as UUID and port number of the target network terminal device, the cloud link service may directly find a data link of the corresponding network terminal device according to the UUID and port number, and perform forwarding operation.
If the data link of the corresponding network terminal equipment is not found through the UUID, the equipment is possibly not on line or the link is disconnected, at the moment, a capacity expansion request can be sent through the UUID and an instruction link corresponding to the port to establish a new link, after the link is established, the forwarding operation can be continued, if the capacity expansion request is sent, the new link is not established within a preset time, the capacity expansion is overtime, and the forwarding operation is ended.
If the request contains the corresponding search instruction, the search instruction is sent to all network terminal devices through all instruction links in the link pool.
It can be understood that the cloud server can record when the network terminal device is on line, so that a continuously updated network terminal registry can be obtained, and the deployed network terminal device can be managed better.
And the cloud server can send heartbeat packets through the instruction link to detect the states of all network terminal devices and obtain a previewable device online condition list, so that the cloud server can also play a role in monitoring.
Step S300, after receiving the file management request, executing file management operation in the file management request, and feeding back response data to the cloud server.
Similar to the cloud server, the network terminal device also has a corresponding network terminal link service to manage all long connections formed, wherein upon receiving a file management request, the network terminal link service sends the request to the network terminal device for direct processing.
For example, if the received file management request is a file management operation of the designated network terminal device, the operation carried in the request can be directly executed, and then corresponding response data is obtained.
If the received file management request is a search, local file retrieval is carried out according to the search instruction, and a retrieval result is sent to the cloud server.
For example, when each network terminal device receives the search instruction, the search instruction is executed, whether the file is in accordance with the local search is searched, if yes, the corresponding file is directly fed back to the cloud server as response data, and if not, the file is not found.
It will be appreciated that this step is also performed through the long connection described above in response to the feedback of the data, thereby forming a loop of back and forth communication.
Specifically, when the cloud server writes a file management request from the client into the link through an available link and sends the file management request to the network terminal equipment, an associated cooperative process or thread is additionally started, and through the thread, data interaction between the link between the cloud and the client and the link between the cloud and the network terminal equipment can be realized. The link between the cloud end and the client end and the link between the cloud end and the network terminal equipment are write-back operation, otherwise, write-back operation is performed, if any one of the two operations is wrong, the link is problematic, the link is not smooth, the other link can be closed, and consumption is reduced.
And step S400, the response data is sent to the client.
For the cloud server, after receiving the response data, the response data can be sent to the client to complete the whole communication, wherein the cloud server gathers all the search results to obtain search data, and sends the search data as response data to the client to complete the whole communication.
It should be noted that, in this embodiment, both the client and the network terminal device are devices in the intranet, and cannot directly communicate with each other, and the cloud server is required to perform route forwarding to perform communication. In this embodiment, the network terminal device is built with a file management system, and executes corresponding file management operations through the file management system, so that the whole file functions are highly dispersed and are not processed by a centralized server, storage pressure is reduced, and reliability and stability are improved. There is also a certain resistance to destructive disasters, and for network terminal devices, only interaction is needed through existing links and servers, so that the actual interaction objects are not limited to a certain client, the interaction is not limited by the actual interaction objects, and the file management scale is easily expanded. The remote file management of decentralization is realized, the safety of the file is ensured, and the HTTP communication is supported by the embodiment, so that the client can perform corresponding operation on the IE webpage of the browser, and the operation is simpler for a user.
