Background technique

IoT device management methods based on REST (Representational State Transfer) architecture are becoming more and more popular. Under the REST architecture, things (such as devices) in the physical world can be described in the form of resources, and CURDN (including create (create), update (modify/update), retrieve (acquire), delete) Delete), notification (notification)) to manipulate resources.

In the process of resource description, a collection resource named collection is defined. A collection resource may include one or more reference resources, and the reference resource may be a collection resource or a non-collection resource. Under the REST architecture, each resource has its own resource attributes, which include: resource identifier, resource type, and interface. For example, the resource identifier can be represented by uri (uniform resource identifier); the resource type can be represented by rt (resource type, resource type); and the interface can be represented by if (interface, interface). In addition, the collection resource also has a links attribute. The collection resource can use the linkadd (add link) interface in the IF attribute to add the URI of a reference resource to the links attribute of the collection resource.

Under the REST architecture, since the collection resource includes at least one reference resource, the deletion process of the collection resource needs further study.

Detailed ways

In order to make the purpose, technical solutions, and advantages of the present application clearer, the implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.

In an IoT system architecture, all physical objects and functional objects are described by resources. For example, the refrigerator is a resource, and the switch of the refrigerator is also a resource. In the process of resource description, two resource types are defined: collective resources and non-collective resources. Among them, a collection resource refers to a linked collection of multiple reference resources, and a reference resource refers to a resource referenced by a collection resource. A collection resource can include one or more reference resources. The reference resource can be a collection resource or a non-collection. resource. The referenced resource may also be referred to as a "linked resource" or other names, which is not limited in this application. Generally, the reference resource in the collection resource is only a link, and the link points to the real address of the reference resource in the network. Optionally, a certain reference resource of a certain collective resource may be on the same physical device as the collective resource, or it may not be on the same physical device.

Regardless of whether it is a collection resource or a non-collection resource, it contains three attributes: resource identifier, resource type, and interface. Among them, the resource identification attribute is used to identify the name of the resource, and the resource identification attribute allows the client to interact with the resource through a specific protocol. The resource type attribute is used to indicate the type of the resource. Generally speaking, a resource type is defined in an IoT technology system, and then different fields, different devices, and different resources can instantiate the resource type. The interface attribute is used to indicate how the resource can be operated, for example, through different interfaces such as create (create) and delete (delete).

For a collection resource, it also contains a link attribute, which is used to indicate the relationship between the collection resource and the reference resource it refers to, and the URI of the reference resource is included in the link attribute. Generally speaking, there is also a linkadd (add link) interface in the interface attribute of the collective resource, and the linkadd interface can add an existing resource to the collective resource as a reference resource for the collective resource. One thing to note is that the linkadd interface adds a URI that references a resource to the link attribute of the collection resource. If the interface attribute of a collection resource contains the create interface, the client can use the create interface to create a new reference resource. The collection resource can directly reference the new reference resource. In addition, the new reference resource can also be used by the new reference resource. Referenced by resources other than the collection resource. In addition, if the if attribute of the resource contains the delete interface, it means that the resource can be deleted. Therefore, if the client needs to delete the reference resource created by the create interface in the collection resource, it needs to be the reference when creating the reference resource Resources add delete interface.

In one example, to delete a non-collection resource, you can delete it directly through the delete interface of the non-collection resource. However, for a collection resource, since the collection resource includes at least one reference resource, when the collection resource is deleted through the delete interface of the collection resource , Also need to recursively delete the reference resources in the collection resources. Suppose that a collection resource A is created through the create interface of a certain resource, and the collection resource A contains the delete interface and the create interface. Then, the collection resource B is created through the create interface of the collection resource A, then the collection resource A contains the collection resource B, Then, the collection resource B is referenced to the collection resource C through the linkadd interface of the collection resource C, and the collection resource C also contains the collection resource B. At this time, the client deletes the collection resource A through the delete interface of the collection resource A. If it is deleting When collecting resource A, delete the collection resource B created through the create interface of the collection resource A. Obviously, it will directly affect the use of the collection resource C, which will affect the management of IoT devices and the normal operation of the IoT system. .

In the technical solution provided by the embodiment of the present application, when deleting a collection resource through the delete interface, the reference resource of the collection resource is first obtained, and then the collection resource and the reference resource are deleted when the reference resource meets the set conditions, where: The setting condition includes that the reference resource is not referenced by other resources except the collection resource. The embodiment of the present application fully considers the characteristics of the reference resource of the collection resource when deleting the collection resource, so that when the collection resource is deleted through the delete interface, the use of resources other than the collection resource will not be affected, thereby solving the problem. The above problems avoid the impact on other resources due to the accidental deletion of reference resources, and ensure the normal and reliable operation of the Internet of Things system.

Hereinafter, the technical solution of the present application will be introduced and explained through several embodiments.

Please refer to FIG. 1, which shows a schematic diagram of an implementation environment provided by an embodiment of the present application. The implementation environment may include: a terminal device 11, a first Internet of Things device 12, and a 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 (such as mobile phones, tablet computers, etc.) with wireless communication functions, in-vehicle devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment ( User Equipment, UE), Mobile Station (MS), etc. For ease of description, in the embodiments of the present application, the devices mentioned above are collectively referred to as terminals.

Collective resources or non-collective resources can be stored in the first Internet of Things device 12. In the case where a collective resource is stored in the first Internet of Things device 12, the collective resource includes a link to the reference resource stored on the second Internet of Things device 13. In different application scenarios, the specific implementation form of the first Internet of Things device 12 may also be different. For example, in a home Internet of Things system, the first Internet of Things device 12 may be a router; for another example, in a cloud platform-based Internet of Things system, the first Internet of Things device 12 may be a server in the cloud. In the embodiment of the present application, the specific manifestation of the first Internet of Things device 12 is not limited, and any device that stores collective resources and/or non-collective resources can be used as the first Internet of Things device 12.

Reference resources may be stored in the second Internet of Things device 13. A collection resource can include one or more reference resources, and the reference resource can be a collection resource or a non-collection resource. The second Internet of Things device 13 may be an access device in the Internet of Things system, such as a terminal device, a smart home device, or other devices with network access capabilities, which are not limited in the 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 device 12 may be one or more; the number of the second Internet of Things device 13 may be one or more.

One thing to note is that the referenced resource may be on the same IoT device as the collective resource, or it may not be on the same IoT device, and the referenced resource may be a collective resource or a non-collective 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, regardless of whether the first Internet of Things device 12 and the second Internet of Things device 13 are the same Internet of Things device or two different Internet of Things devices, the following method procedures provided in the embodiments of the present application are applicable.

In an example, taking a home Internet of Things system as an example, the terminal device 11 may be a mobile phone used by the user, the first Internet of Things device 12 may be a router, and the second Internet of Things device 13 may be a smart TV, a smart speaker, a smart air conditioner, Smart home appliances such as smart lights, smart doors and windows, smart curtains, smart sockets, etc. Optionally, a client can be installed and running in the terminal device 11, and the client can initiate a resource deletion request to the first Internet of Things device 12, such as a deletion request for a collective resource or a deletion request for a non-collective resource . In the case where the first Internet of Things device 12 stores non-collective resources, after receiving the resource deletion request, the first Internet of Things device 12 can directly delete the non-collective resources. In the case that the first Internet of Things device 12 saves a collective resource, after the first Internet of Things device 12 receives the resource deletion request, it can delete the collective resource and the reference resource saved in the second Internet of Things device 13 For the specific deletion process, please refer to the following method example, which will not be repeated here.

Please refer to FIG. 2, which shows a flowchart of a resource deletion method provided by an embodiment of the present application. The method can be applied to the implementation environment shown in FIG. 1. The method can include the following steps (210-230):

Step 210: The Internet of Things device determines the target resource to be deleted.

The target resource refers to the resource to be deleted. The target resource can be a collective resource or a non-collective resource; the number of the target resource can be one or more. The types are not limited. In the embodiment of the present application, the target resource to be deleted may be determined by the Internet of Things device. Optionally, the Internet of Things device can determine the target resource to be deleted according to the request of the terminal device. For example, the Internet of Things device receives a resource deletion request from the terminal device, and determines the target resource to be deleted according to the resource deletion request; the Internet of Things device also The target resource to be deleted can be determined by oneself according to the state of the resource managed by it. For example, the Internet of Things device determines the resource that has not been used in the last 48 hours as the target resource to be deleted according to the state of the resource managed by it. This embodiment of the application There is no restriction on the specific method for the IoT device to determine the target resource. In actual applications, the IoT device can either use one of the two optional methods to determine the target resource alone, or use a combination of the two optional methods. To determine the target resource, other methods can also be used to determine the target resource. The embodiments of the present application provide multiple ways to determine the target resource, which can improve the flexibility of the IoT device in determining the target resource and improve the efficiency of resource management.

In an example, as shown in Figure 3, the above method further includes the following steps (212-214):

Step 212: The terminal device sends a resource deletion request to the Internet of Things device.

The resource deletion request is used to request the deletion of the target resource. Optionally, in order for the IoT device to quickly and easily grasp the target resource to be deleted, the resource deletion request sent by the terminal device may include the resource identifier of the target resource, so that the IoT device receives After the resource deletion request is received, the resource deletion request can be parsed to obtain the information of the target resource to be deleted.

Step 214: When the resource deletion request satisfies the third condition, the Internet of Things device executes the step of deleting the target resource.

In the embodiment of the present application, after the Internet of Things device receives the resource deletion request, it can detect the resource deletion request to determine whether the requesting party can delete the target resource. Optionally, the IoT device may detect whether the resource deletion request meets the third condition, and if the resource deletion request meets the third condition, execute the step of deleting the target resource. 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 a deletion interface, and the requester has the right to delete the target resource. The requesting party refers to the party that sends the resource deletion request. For example, the requesting party may be the terminal device introduced in the foregoing implementation environment embodiment. The embodiment of the present application does not limit the method for determining the third condition. Optionally, the third condition may be pre-defined by an agreement, or may be specifically determined by the Internet of Things device according to resource conditions and actual security requirements.

In the case that the target resource is a collective resource, and the IoT device determines that the resource deletion request satisfies the third condition, it can execute the step of deleting the target resource. However, since the collective resource contains at least one reference resource, in order to make a more detailed and sufficient Considering that it is necessary to perform further analysis and processing on the referenced resource of the target resource, and then the Internet of Things device may perform step 210 and subsequent steps to delete the referenced resource of the target resource. The embodiment of the present application does not limit the execution order of step 210 and step 214. Step 210 may be executed simultaneously with step 214, may also be executed before step 214, or may be executed after step 214.

Step 220: In a case where the target resource is a collective resource, the Internet of Things device obtains the first reference resource.

In the embodiment of this application, after the Internet of Things device determines the target resource to be deleted, or the Internet of Things device determines the target resource to be deleted, it can determine whether the target resource is a collective resource. The embodiment of this application determines the target for the Internet of Things device. The specific timing of whether the resource is a collective resource is not limited. Optionally, in the case where it is determined that the target resource is a non-collective resource, the IoT device may delete the target resource, and at the same time also delete the resource attribute of the target resource. Optionally, when the target resource is referenced by other resources, when the IoT device deletes the target resource, it also deletes the reference relationship of the target resource included in the resource attribute of the target resource. In the case of determining that the target resource is a collective resource, since the collective resource contains at least one reference resource, in order to conduct a comprehensive analysis of the reference resource of the target resource, so as to avoid the subsequent deletion of the target resource from affecting other resources other than the target resource. The IoT device can first obtain the first reference resource. Wherein, the target resource may include at least one reference resource. The embodiment of the present application only takes the first reference resource as an example for illustration. The first reference resource may be any reference resource of the target resource. Steps for deleting other reference resources of the target resource , Can be deduced by referring to the deletion steps of the first referenced resource. Optionally, the first reference resource may be a collective resource or a non-collective resource. The embodiment of the present application does not limit the resource type of the first reference resource.

Step 230: When the first reference resource meets the first condition, the Internet of Things device deletes the target resource and the first reference resource.

After the Internet of Things device obtains the first reference resource, it can detect the first reference resource to determine whether deleting the first reference resource will affect other resources except the target resource. Optionally, the Internet of Things device may detect whether the first referenced resource meets the first condition, and in the case that the first referenced resource meets the first condition, it is determined that deleting the first referenced resource will not affect other resources except the target resource. The resource has an impact, so that the IoT device can delete the target resource and the first referenced resource. Optionally, the first condition includes that the first referenced resource is not referenced by other resources except the target resource. If the first referenced resource is referenced by other resources except the target resource, it means that deleting the first referenced resource will affect the normal use of other resources. Optionally, in order to more reliably and accurately determine whether the first referenced resource can be deleted, and whether deleting the first referenced resource will affect the use of other resources, the first condition further includes at least one of the following: the first referenced resource supports To delete the interface, the requesting party has the right to delete the first referenced resource, and the first referenced resource is created through the creation interface of the target resource. Among them, the requesting party refers to the party that sends the resource deletion request. The embodiment of the present application does not limit the method for determining the first condition. Optionally, the first condition may be pre-defined by an agreement, or may be specifically determined by the Internet of Things device according to resource conditions and actual security requirements.

Exemplarily, in order to provide a specific way to determine whether the first condition is met, after the above step 220, the method further includes: the Internet of Things device detects whether the first referenced resource supports the deletion interface; in the case that the first referenced resource supports the deletion interface , The Internet of Things device detects whether the requesting party has the right to delete the first referenced resource; in the case that the requesting party has the right to delete the first referenced resource, the Internet of Things device detects whether the first referenced resource is a resource other than the target resource When the first referenced resource is not referenced by other resources except the target resource, the IoT device detects whether the first referenced resource is created through the creation interface of the target resource; the first referenced resource is passed When the creation interface of the target resource is created, it is determined that the first reference resource satisfies the first condition. It should be noted that this exemplary embodiment only shows a possible sequence of detecting whether the first referenced resource meets the first condition. Those skilled in the art will understand the technical solutions of the embodiments of the present application. It is easy to think of other procedures for detecting whether the first referenced resource meets the first condition, and other content that can be included in the first condition, but they should all fall within the protection scope of the present application.

In the embodiment of the present application, when the first referenced resource meets the first condition, the IoT device executes the steps of deleting the target resource and the first referenced resource. When the IoT device deletes the target resource, the resource attribute of the target resource is also deleted. Optionally, when the target resource is referenced by other resources, the IoT device deletes the target resource at the same time as the resource of the target resource. The reference relationship of the target resource contained in the attribute; when the IoT device deletes the first reference resource, the resource attribute of the first reference resource is also deleted, and the target resource contained in the resource attribute of the target resource and the first reference resource are also deleted Reference relationship. Wherein, the reference relationship of the target resource includes the reference relationship between the target resource and the first reference resource. Optionally, the IoT device can delete the target resource and the first reference resource at the same time; it can also delete the first reference resource first, and then delete the target resource; it can also delete the target resource first, and then delete the first reference resource. This application The embodiment does not limit the sequence of deleting the first reference resource and deleting the target resource by the IoT device. 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, and then determine whether the first referenced resource satisfies the first condition, and when the first referenced resource satisfies the first condition , Delete the first reference resource.

Optionally, as shown in FIG. 4, in order to ensure that deleting the target resource will not affect other resources except the target resource, after the above step 220, it further includes step 232: when the first referenced resource does not meet the first condition In this case, the IoT device deletes the target resource, and keeps the first reference resource without deleting. In the embodiment of the present application, the first referenced resource does not meet the first condition, which means that deleting the first referenced resource will also affect other resources except the target resource. At this time, the IoT device deletes the target resource, and The step of keeping the first reference resource without deleting, that is, the IoT device deletes the target resource, and at the same time also deletes the reference relationship between the target resource and the first reference resource, but because the IoT device retains the first reference resource and does not delete it, Therefore, it will not affect other resources other than the target resource, for example, it will not affect other collective resources that reference the first referenced resource.

In an example, as shown in Figure 5, the above method further includes the following steps (240-250):

Step 240: In the case where it is determined to delete the first reference resource, and the first reference resource is a collective resource, acquire the second reference resource.

Since there may be a situation in which the referenced resource of a certain collective resource is still a collective resource in practical applications, the embodiment of the present application provides a corresponding resource deletion method in response to this situation. When the IoT device determines that the target resource is a collective resource, the reference resource of the target resource (ie the first reference resource) is also a collective resource, and it is determined to delete the reference resource of the target resource (ie the first reference resource), obtain the second reference Resources, where the second reference resource is a reference resource of the first reference resource.

It should be noted that when the first referenced resource is a collection resource, the first referenced resource may include one or more referenced resources, and the second referenced resource may be any referenced resource of the first referenced resource. The embodiments of this application only Taking the step of deleting the second referenced resource as an example for illustration, the steps of deleting other referenced resources of the first referenced resource can be derived by analogy with reference to the deleting step of the second referenced resource.

Step 250: When the second reference resource meets the second condition, delete the second reference resource.

After the Internet of Things device obtains the second referenced resource, it can detect the second referenced resource to determine whether deleting the second referenced resource will affect other resources other than the first referenced resource. Optionally, the Internet of Things device may detect whether the second referenced resource meets the second condition, and in the case that the second referenced resource meets the second condition, it is determined that deleting the second referenced resource will not affect any other than the first referenced resource. Other resources have an impact, so that the IoT device can delete the second reference resource. Optionally, the second condition includes that the second referenced resource is not referenced by other resources except the first referenced resource. If the second referenced resource is referenced by other resources except the first referenced resource, it means that deleting the second referenced resource will affect the normal use of other resources. Optionally, in order to more reliably and accurately determine whether the second referenced resource can be deleted, and whether the deletion of the second referenced resource will affect the use of other resources, the second condition further includes at least one of the following: Support for the second referenced resource To delete the interface, the requesting party has the right to delete the second reference resource, and the second reference resource is created through the creation interface of the first reference resource. That is, the substance of the second condition can be the same as that of the first condition. The only difference is that the first condition is used to determine that deleting the first referenced resource will not affect other resources except the target resource. The second condition is used It is determined that deleting the second referenced resource will not affect other resources except the first referenced resource. Optionally, the substance of the second condition and the first condition may also be different. For example, the second condition may only include that the second referenced resource is not referenced by other resources other than the first referenced resource. This embodiment of the present application The specific content of the second condition and the relationship between the second condition and the first condition are not limited. Optionally, the second condition may be pre-defined by an agreement, or may be specifically determined by the Internet of Things device according to resource conditions and actual security requirements.

Optionally, as shown in FIG. 5, in order to further ensure that deleting the second referenced resource will not affect other resources except the first referenced resource, after the above step 240, it further includes step 252: when the second referenced resource is not When the second condition is met, the IoT device deletes the first referenced resource, and keeps the second referenced resource without deleting. That is, when the IoT device deletes the first reference resource, the reference relationship between the first reference resource and the second reference resource is also deleted, but because the IoT device retains the second reference resource and does not delete it, it will not reference the first reference resource. Resources other than the resource have an impact, such as no impact on other collective resources that reference the second referenced resource.

It should be noted that after understanding the technical solutions of the present application, those skilled in the art will easily think of the resource deletion performed when the IoT device determines to delete the second referenced resource, and the second referenced resource is also a collective resource The steps, which can be derived by analogy from the steps performed by the Internet of Things device when the first reference resource is a collective resource, and will not be repeated here in the embodiment of the present application.

In summary, in the technical solution provided by the embodiments of the present application, when the target resource to be deleted is determined, and the target resource is a collective resource, by obtaining the reference resource of the target resource, it is determined that the reference resource satisfies the conditions. In this case, the reference resource is deleted again; compared to when the related technology deletes the collection resource, all the reference resources included in the collection resource are deleted at the same time. The reference resource included in the collection resource is analyzed and processed, and the reference resource is deleted only when it is confirmed that the reference resource can be deleted, so that more detailed and sufficient considerations are made during the resource deletion process to avoid accidental deletion Quoting resources results in an impact on other resources, ensuring the normal and reliable operation of the Internet of Things system.
