Description

Resource deleting method, device, equipment and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for deleting a resource.

Background

Internet of things device management methods based on REST (Representational State Transfer) architecture are becoming more popular. Under the REST architecture, things in the physical world (such as devices) can be described in a manner of using resources (resources), and resources are operated in a manner of CURDN (including create, update, retrieve, delete, notification).

In the resource description process, an aggregate resource named collection is defined. An aggregate resource may include one or more referenced resources, which may be either aggregate resources or non-aggregate resources. Under the REST architecture, each resource has its own resource attribute, which includes: resource identification, resource type, and interface. For example, the resource identifier may be represented by uri (uniform resource identifier); the resource type may be represented by rt (resource type); an interface may be represented by if (interface). In addition, a links attribute exists for the set resource. An aggregate resource may add a URI that references the resource to the links attribute of the aggregate resource using the linkadd interface in the IF attribute.

Under the REST architecture, since the set resource includes at least one reference resource, further research is required for the deletion process of the set resource.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

In an internet of things system architecture, all physical objects, functional objects and the like are described by using resources. For example, a refrigerator is a resource, and a switch of the refrigerator is also a resource. In the resource description process, two resource types are defined: an aggregated resource and a non-aggregated resource. The set resource refers to a linked set of multiple reference resources, the reference resource refers to a resource referenced by the set resource, one set resource may include one or more reference resources, and the reference resource may be a set resource or a non-set resource. A referenced resource may also be referred to as a "linked resource" or by other names, which are not limited in this application. Typically the referenced resource in the collection resource is just a link (link) that points to the real address of the referenced resource in the network. Alternatively, a reference resource of a set of resources may or may not be on the same physical device as the set of resources.

Whether an aggregate resource or a non-aggregate resource, contains three attributes of a resource identification, a resource type, and an interface. The resource identification attribute is used for identifying the name of the resource, and the resource identification attribute allows a client (client) to perform interactive operation on the resource through a specific protocol. The resource type attribute is used to indicate the type of the resource. Generally, a resource type is defined in an internet of things technology system, and then different domains, different devices, and different resources can instantiate the resource type. The interface attribute is used to indicate which way the resource can be operated, e.g., by different interfaces such as create and delete.

For an aggregate resource, a link attribute is also included, the link attribute indicating the relationship between the aggregate resource and the referenced resource to which it refers, and the uri of the referenced resource is included in the link attribute. Generally, a linkadd (link addition) interface also exists in the interface attribute of the aggregate resource, and the linkadd interface can add an existing resource to the aggregate resource to serve as a reference resource of the aggregate resource. It should be noted that the linkadd interface adds an uri referencing a resource to the link attribute of the aggregate resource. If the interface attribute of an aggregate resource contains a create interface, the client can create a new referenced resource by using the create interface, the aggregate resource can directly reference the new referenced resource, and in addition, the new referenced resource can also be referenced by other resources except the aggregate resource. In addition, if the if attribute of the resource includes a delete interface, it indicates that the resource is deletable, so if the client needs to delete a referenced resource created using the create interface in the set resource, it needs to add the delete interface to the referenced resource when creating the referenced resource.

In one example, a non-aggregate resource is deleted directly through the delete interface of the non-aggregate resource, however, for an aggregate resource, since the aggregate resource includes at least one reference resource, when the aggregate resource is deleted through the delete interface of the aggregate resource, the reference resource in the aggregate resource also needs to be deleted recursively. Assuming that an assembly resource a is created through a create interface of a certain resource, and the assembly resource a includes a delete interface and a create interface, then an assembly resource B is created through the create interface of the assembly resource a, the assembly resource a includes the assembly resource B, then the assembly resource B is referred to the assembly resource C through a linkadd interface of the assembly resource C, and the assembly resource C also includes the assembly resource B, at this time, the client deletes the assembly resource a through the delete interface of the assembly resource a, and if the assembly resource a is deleted while the assembly resource B created through the create interface of the assembly resource a is deleted together, it is obvious that the use of the assembly resource C is directly influenced, thereby influencing the management of the internet of things device and the normal operation of the internet of things system.

In the technical solution provided in the embodiment of the present application, when a set resource is deleted through a delete interface, a reference resource of the set resource is obtained first, and then the set resource and the reference resource are deleted when the reference resource meets a set condition, where the set condition includes that the reference resource is not referred by other resources except the set resource. According to the method and the device, when the set resource is deleted, the characteristics of the quoted resource of the set resource are fully considered, so that the use of other resources except the set resource cannot be influenced when the set resource is deleted through the delete interface, the problems are solved, the influence on other resources caused by the mistaken deletion of the quoted resource is avoided, and the normal and reliable operation of the Internet of things system is ensured.

The technical solution of the present application will be described below by means of several embodiments.

Referring to fig. 1, a schematic diagram of an implementation environment provided by an embodiment of the present application is shown, where the implementation environment may include: the terminal device 11, the first internet of things device 12 and the second internet of things device 13. The implementation environment may be an internet of things system.

The terminal device 11 may include various handheld devices (e.g., Mobile phones, tablet computers, etc.) having wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of User Equipment (UE), Mobile Stations (MS), and so on. For convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as a terminal.

The first internet of things device 12 may store an aggregate resource or a non-aggregate resource. In the case where an aggregate resource is stored in the first internet-of-things device 12, the aggregate resource includes a link (link) to a reference resource stored on the second internet-of-things device 13. The specific implementation form of the first internet of things device 12 may also be different in different application scenarios. For example, in a home internet of things system, the first internet of things device 12 may be a router; for another example, in the cloud platform-based internet of things system, the first internet of things device 12 may be a server in the cloud. In this embodiment, a specific representation form of the first internet of things device 12 is not limited, and any device storing aggregated resources and/or non-aggregated resources may be used as the first internet of things device 12.

The second networked device 13 may have a referenced resource stored therein. One aggregation resource may include one or more reference resources, and the reference resources may be aggregation resources or non-aggregation resources. The second networking device 13 may be an access device in an internet of things system, such as a terminal device, an intelligent home device, or other devices with network access capability, which is not limited in this embodiment of the present application.

The terminal device 11 may communicate with the first internet of things device 12 through a wireless or wired network, and the first internet of things device 12 may also communicate with the second internet of things device 13 through a wireless or wired network. In addition, the number of the first internet of things devices 12 may be one or multiple; the number of the second networked devices 13 may be one or more.

It should be noted that the referenced resource may be on the same internet of things device as the aggregated resource, or may not be on the same internet of things device, and the referenced resource may be an aggregated resource or a non-aggregated resource. That is, the first internet of things device 12 and the second internet of things device 13 may be the same internet of things device or two different internet of things devices. However, the following method flow provided in the embodiment of the present application is applicable to the first internet of things device 12 and the second internet of things device 13, which are the same internet of things device, or two different internet of things devices.

In an example, taking a home internet of things system as an example, the terminal device 11 may be a mobile phone used by a user, the first internet of things device 12 may be a router, and the second internet of things device 13 may be a smart home device such as a smart television, a smart sound box, a smart air conditioner, a smart lamp, a smart door/window, a smart curtain, and a smart socket. Optionally, a client (client) may be installed and operated in the terminal device 11, and the client may be capable of initiating a resource deletion request to the first internet of things device 12, such as a deletion request for an aggregated resource or a deletion request for a non-aggregated resource. In the case where the non-aggregate resources stored in the first internet of things device 12 are non-aggregate resources, the first internet of things device 12 may directly delete the non-aggregate resources after receiving the resource deletion request. In the case that the aggregate resources are stored in the first internet of things device 12, after receiving the resource deletion request, the first internet of things device 12 may delete the aggregate resources and the reference resources stored in the second internet of things device 13, and for a specific deletion process, please refer to the following method example, which is not described herein again.

Referring to fig. 2, a flowchart of a resource deletion method provided by an embodiment of the present application is shown, and the method may be applied to the implementation environment shown in fig. 1. The method comprises the following steps (210-230):

step 210, the internet of things device determines a target resource to be deleted.

The target resource refers to a resource to be deleted, and the target resource can be a collective resource or a non-collective resource; the number of the target resource may be one or multiple, and the specific number and resource type of the target resource are not limited in the embodiment of the application. In the embodiment of the application, the target resource to be deleted can be determined by the internet of things device. Optionally, the internet of things device may determine the target resource to be deleted according to the request of the terminal device, for example, the internet of things device receives the resource deletion request of the terminal device, and determines the target resource to be deleted according to the resource deletion request; the internet of things equipment can also determine the target resource to be deleted by itself according to the state of the resource managed by the internet of things equipment, for example, the internet of things equipment determines the resource which is not used in the last 48 hours as the target resource to be deleted according to the state of the resource managed by the internet of things equipment. According to the method and the device, the target resource is determined in multiple modes, the flexibility of determining the target resource by the Internet of things equipment can be improved, and the resource management efficiency is improved.

In one example, as shown in FIG. 3, the method further comprises the following steps (212-214):

in step 212, the terminal device sends a resource deletion request to the internet of things device.

Optionally, in order to enable the internet of things device to conveniently and quickly master the target resource to be deleted, the resource deletion request sent by the terminal device may include a resource identifier of the target resource, so that after receiving the resource deletion request, the internet of things device parses the resource deletion request, and then may obtain information of the target resource to be deleted.

Step 214, in the case that the resource deletion request meets the third condition, the internet of things device executes the step of deleting the target resource.

In the embodiment of the application, after the internet of things device receives the resource deletion request, the resource deletion request can be detected to determine whether the requester can delete the target resource. Optionally, the internet of things device may execute the step of deleting the target resource by detecting whether the resource deletion request satisfies the third condition, and in a case that the resource deletion request satisfies the third condition. Wherein the third condition is a condition for determining that the requester can delete the target resource, optionally, the third condition includes but is not limited to: the target resource supports the deletion interface, and the requester has the right to delete the target resource. The requester is a party that sends the resource deletion request, and for example, the requester may be the terminal device described in the embodiment of the implementation environment. The determination method of the third condition is not limited in the embodiment of the application, and optionally, the third condition may be predefined by a protocol, or may be specifically determined by the internet of things device according to the resource condition, the actual security requirement, and the like.

In the case that the target resource is an aggregated resource, the internet of things device may execute the step of deleting the target resource when determining that the resource deletion request satisfies the third condition, but since the aggregated resource includes at least one reference resource, in order to take more detailed and sufficient consideration into consideration, the reference resource of the target resource needs to be further analyzed, and then the internet of things device may execute step 210 and the following steps to delete the reference resource of the target resource. In the embodiment of the present application, the execution sequence of step 210 and step 214 is not limited, and step 210 may be executed simultaneously with step 214, may be executed before step 214, and may also be executed after step 214.

Step 220, in the case that the target resource is the set resource, the internet of things device obtains the first reference resource.

In the embodiment of the application, after the internet of things device determines the target resource to be deleted, or while the internet of things device determines the target resource to be deleted, whether the target resource is the collective resource or not can be determined, and the specific time for determining whether the target resource is the collective resource or not by the internet of things device is not limited in the embodiment of the application. Optionally, when it is determined that the target resource is a non-aggregated resource, the internet of things device may delete the target resource, and delete the resource attribute of the target resource at the same time. Optionally, in a case that the target resource is referred to by another resource, the internet of things device deletes the target resource, and at the same time, deletes the reference relationship of the target resource included in the resource attribute of the target resource. Under the condition that the target resource is determined to be the set resource, the set resource comprises at least one reference resource, and in order to comprehensively analyze the reference resource of the target resource and avoid the influence on other resources except the target resource when the target resource is deleted subsequently, the internet of things equipment can obtain the first reference resource first. The target resource may include at least one referenced resource, and the embodiment of the present application only exemplifies a first referenced resource, where the first referenced resource may be any one referenced resource of the target resource, and the step of deleting other referenced resources of the target resource may be obtained by analogy with reference to the step of deleting the first referenced resource. Optionally, the first referenced resource may be an aggregated resource or a non-aggregated resource, and the resource type of the first referenced resource is not limited in this embodiment of the application.

Step 230, in a case that the first quoted resource meets the first condition, the internet of things device deletes the target resource and the first quoted resource.

After the internet of things device acquires the first reference resource, the first reference resource can be detected to determine whether deleting the first reference resource affects other resources except the target resource. Optionally, the internet of things device may determine that deleting the first referenced resource does not affect other resources except the target resource by detecting whether the first referenced resource meets a first condition or not, and when the first referenced resource meets the first condition, the internet of things device may delete the target resource and the first referenced resource. Optionally, the first condition includes that the first referenced resource is not referenced by a resource other than the target resource. If the first referenced resource is referenced by a resource other than the target resource, then it is stated that deleting the first referenced resource will have an impact on the normal use of the other resource. Optionally, in order to more reliably and accurately determine whether the first referenced resource can be deleted and whether deleting the first referenced resource affects the use of other resources, the first condition further includes at least one of: the first referenced resource supports a deletion interface, the requester has the right to delete the first referenced resource, and the first referenced resource is created through a creation interface of the target resource. The requester is the party that sends the resource deletion request. The determining mode of the first condition is not limited in the embodiment of the application, and optionally, the first condition may be predefined by a protocol, or may be specifically determined by the internet of things device according to the resource condition, the actual security requirement, and the like.

Illustratively, in order to provide a way of specifically determining whether the first condition is satisfied, the step 220 further includes: the method comprises the steps that the Internet of things equipment detects whether a first quoted resource supports interface deletion; under the condition that the first quoted resource supports the deletion of the interface, the Internet of things equipment detects whether a requester has the right to delete the first quoted resource; under the condition that a requester has the right to delete a first referenced resource, the Internet of things equipment detects whether the first referenced resource is referenced by other resources except the target resource; under the condition that the first reference resource is not referenced by other resources except the target resource, the Internet of things equipment detects whether the first reference resource is created through a creation interface of the target resource; in a case where the first referenced resource is created through a creation interface of the target resource, it is determined that the first referenced resource satisfies a first condition. It should be noted that this exemplary embodiment only shows one possible order for detecting whether the first cited resource satisfies the first condition, and those skilled in the art will easily understand other orders for detecting whether the first cited resource satisfies the first condition after understanding the technical solutions of the embodiments of the present application, and other contents that may be included in the first condition, but all shall fall within the scope of the present application.

In the embodiment of the application, the internet of things device executes the step of deleting the target resource and the first quoted resource when the first quoted resource meets the first condition. When the target resource is deleted by the internet of things device, the resource attribute of the target resource is deleted, optionally, when the target resource is referred by other resources, the internet of things device deletes the target resource, and simultaneously deletes the reference relation of the target resource included in the resource attribute of the target resource; when the internet of things equipment deletes the first referenced resource, the resource attribute of the first referenced resource and the reference relation between the target resource and the first referenced resource contained in the resource attribute of the target resource are deleted. And the reference relation of the target resource comprises the reference relation between the target resource and the first reference resource. Optionally, the internet of things device may delete the target resource and the first referenced resource at the same time; or deleting the first reference resource first and then deleting the target resource; the target resource can also be deleted first, and then the first quoted resource is deleted, and the sequence of deleting the first quoted resource and the target resource by the internet of things equipment is not limited in the embodiment of the application. For example, the internet of things device may delete the target resource when it is determined that the resource deletion request satisfies the third condition, then determine whether the first referenced resource satisfies the first condition, and delete the first referenced resource when the first referenced resource satisfies the first condition.

Optionally, as shown in fig. 4, in order to ensure that the deletion of the target resource does not affect other resources except the target resource, after the step 220, a step 232 is further included: and under the condition that the first quoted resource does not meet the first condition, the target resource is deleted by the Internet of things equipment, and the first quoted resource is reserved and not deleted. In the embodiment of the application, the first quoted resource does not meet the first condition, that is, the deletion of the first quoted resource is indicated, and other resources except the target resource are also affected, at this time, the internet of things device executes the step of deleting the target resource and reserving the first quoted resource for not deleting, that is, the internet of things device deletes the target resource and deletes the quoted relation between the target resource and the first quoted resource, but because the internet of things device reserves the first quoted resource for not deleting, other resources except the target resource are not affected, for example, other set resources which quote the first quoted resource are not affected.

In one example, as shown in FIG. 5, the method further comprises the following steps (240-250):

and 240, acquiring the second referenced resource under the condition that the first referenced resource is determined to be deleted and the first referenced resource is the collection resource.

In practical application, a situation that a referenced resource of a certain set resource is still a set resource may occur, and the embodiment of the present application provides a corresponding resource deletion method for the situation. The method comprises the steps that the IOT equipment acquires a second reference resource under the condition that the target resource is determined to be an aggregate resource, the reference resource (namely, the first reference resource) of the target resource is also the aggregate resource, and the reference resource (namely, the first reference resource) of the target resource is determined to be deleted, wherein the second reference resource is the reference resource of the first reference resource.

It should be noted that, when the first referenced resource is an aggregate resource, the first referenced resource may include one or more referenced resources, and the second referenced resource may be any one of the referenced resources of the first referenced resource, in this embodiment, the deletion step of the second referenced resource is merely used as an example for illustration, and the deletion step of other referenced resources of the first referenced resource may be obtained by analogy with reference to the deletion step of the second referenced resource.

And 250, deleting the second reference resource under the condition that the second reference resource meets a second condition.

After the internet of things equipment acquires the second quoted resource, the second quoted resource can be detected to determine whether deleting the second quoted resource affects other resources except the first quoted resource. Optionally, the internet of things device may determine that deleting the second referenced resource does not affect other resources except the first referenced resource by detecting whether the second referenced resource satisfies a second condition, where the second referenced resource satisfies the second condition, so that the internet of things device may delete the second referenced resource. Optionally, the second condition includes that the second referenced resource is not referenced by a resource other than the first referenced resource. If the second referenced resource is referenced by a resource other than the first referenced resource, then it is stated that deleting the second referenced resource will have an impact on the normal use of the other resource. Optionally, in order to more reliably and accurately determine whether the second referenced resource can be deleted and whether deleting the second referenced resource may affect the use of other resources, the second condition further includes at least one of: the second referenced resource supports a deletion interface, the requester has the right to delete the second referenced resource, and the second referenced resource is created through the creation interface of the first referenced resource. That is, the second condition may be the same as the substance of the first condition described above, except that the first condition is used to determine that deleting the first referenced resource does not affect the other resources except the target resource, and the second condition is used to determine that deleting the second referenced resource does not affect the other resources except the first referenced resource. Optionally, the second condition may also be different from the substance of the first condition, for example, the second condition may only include that the second referenced resource is not referenced by other resources besides the first referenced resource, and the embodiment of the present application does not limit the specific content of the second condition, nor the relationship between the second condition and the first condition. Optionally, the second condition may be predefined by a protocol, or may be specifically determined by the internet of things device according to a resource condition, an actual security requirement, and the like.

Optionally, as shown in fig. 5, in order to further ensure that deleting the second referenced resource does not affect other resources except the first referenced resource, after the step 240, the method further includes a step 252: and under the condition that the second quoted resource does not meet the second condition, the Internet of things equipment deletes the first quoted resource and reserves the second quoted resource for not deleting. That is, the internet of things device deletes the first referenced resource, that is, deletes the reference relationship between the first referenced resource and the second referenced resource, but since the internet of things device reserves the second referenced resource to be not deleted, no influence is exerted on other resources except the first referenced resource, for example, no influence is exerted on other set resources that reference the second referenced resource.

It should be noted that, after understanding the technical solution of the present application, a person skilled in the art will easily think of a resource deletion step executed when the internet of things device determines to delete the second referenced resource, and the second referenced resource is also an aggregated resource, which can be obtained by analogy with steps executed by the internet of things device when the first referenced resource is an aggregated resource, and the embodiment of the present application is not described herein again.
