The embodiments of this application include at least part of the following content.

Figure 2 is a schematic flowchart of a resource subscription method provided by an embodiment of the present application. As shown in Figure 2, the method includes:

S201. The client sends a first subscription request (SubscribeRequest) to the proxy device.

For example, the first subscription request may carry the resource identifier or resource path: S1/EP0/C1. Among them, S1 identifies device ID 1 (nodeid1); EP0 identifies endpoint ID 0 (endpointid0); C1 identifies cluster ID 1 (cluster ID1). The device identifier may be a resource node identifier; a resource node may include one or more endpoints; the cluster identifier may be used to subscribe to resources in the cluster corresponding to the cluster identifier (or resources corresponding to the cluster identifier).

S201 can also be described as: the client sends a request to subscribe to the C1 resource on the resource node to the proxy device.

S202. The proxy device sends the first report data (ReportData) to the client.

For example, the first report data may carry S1/EP0/C1:[NO_SUBSCRIPTION]. For example, S1/EP0/C1:[NO_SUBSCRIPTION] included in the first report data indicates that the proxy device has not temporarily subscribed to the resource of the resource node (which may be the resource corresponding to the cluster identifier).

Before sending the first report data, the proxy device needs to check whether the client has the permission to subscribe to C1 on the resource node (the permission can be the view permission). The proxy device has proxyview permissions on the resource node Access Control List (ACL) cluster resource, and the proxy device can subscribe to or read the ACL cluster. Based on this, the proxy device can determine whether the client can subscribe to the C1 resource by obtaining the client's permission on the C1 resource on the resource node. It should be noted that whether the client directly subscribes to the target resource of the resource node (for example, C1 resource) or subscribes to the target resource through a proxy device, it needs to have the permission to subscribe to the target resource of the resource node (View permission), that is, on the resource node The ACL Cluster needs to have the access control entry (Access Control Entry, ACE) corresponding to the client. However, the problem with the embodiment of the present application is that the proxy device needs to obtain all ACE records, which leads to the expansion of the authority of the proxy device and increases the risk of information leakage.

S203. The client sends a first status report (StatusReponse) to the proxy device. The first status report can carry its own status as OK.

S204. The proxy device sends the first subscription response (SubscribeResponse) to the client.

S205. The proxy device sends a second subscription request to the resource node. The second subscription request may carry the resource identifier or resource path EP0/C1.

In this way, the proxy device initiates a subscription to the C1 resource on the resource node. After the subscription is successful, continue processing the client's subscription process.

S206. The resource node sends second report data to the proxy device. The second report data may carry EP0/C1: {a=1, b=2}.

Among them, a=1 and b=2 indicate that the attributes a and b in the cluster have changed, and the changed values are a=1 and b=2.

S207. The proxy device sends a second status report to the resource node. The second status report may carry its own status as OK.

S208. The resource node sends a second subscription response to the proxy device.

S209. The proxy device sends third report data to the client. The third report data may carry S1/EP0/C1: {a=1, b=2}.

S210. The client sends a third status report to the proxy device. The third status report can carry its own status as OK.

In any embodiment of this application, the subscription device and the client in any of the above embodiments may be the same device, the target proxy device may be the above proxy device, and the target node device may be the same as the resource in any of the above embodiments.

Optionally, the first subscription request may include a minimum time interval and a maximum time interval. Optionally, the maximum time interval may be used to indicate that within the maximum time interval, the target proxy device needs to send a notification message, or needs to send one notification message or two notification messages. The minimum time interval may be used to indicate that the time interval between two adjacent notification messages needs to be greater than or equal to the minimum time interval. For example, the time interval between two adjacent notification messages may be the minimum time interval or the maximum time interval.

In some embodiments, the first subscription request includes a minimum time interval and a maximum time interval. The minimum time interval is the time interval for the target proxy device to send the first notification message, and the maximum time interval is the time interval for the target proxy device to send the first notification message. The time interval between notification messages and/or second notification messages. In this case, if the target proxy device detects the reported message within the minimum time interval, it sends the first notification message to the subscribing device; the target proxy device does not detect the reported message within the minimum time interval, and the target proxy device does not detect the reported message within the maximum time interval. If a reported message is detected within the specified time interval, the target proxy device sends the first notification message to the subscribing device; if the target proxy device does not detect the reported message within the minimum time interval, and does not detect the reported message within the maximum time interval, The target proxy device sends a second notification message to the subscribing device.

For example, if the target proxy device does not detect a reported message within the maximum time interval, the target proxy device sends a second notification message to the subscribing device. For another example, if the target proxy device does not detect a reported message within the minimum time interval, and detects one or more reported messages within the maximum time interval, the target proxy device detects the error message at the end of the maximum time interval or after the maximum time interval. , sending a first notification message to the subscribing device, and/or, detecting one or more reporting messages within the minimum time interval, and detecting one or more reporting messages within the maximum time interval other than the minimum time interval. In the case of , the target proxy device sends the first notification message to the subscribing device at the end of the minimum time interval and the maximum time interval respectively, or after the minimum time interval and the maximum time interval respectively, and/or within the minimum time interval. If no reported message is detected, and one or more reported messages are not detected within the maximum time interval, the target proxy device sends a second notification message to the subscribing device at the end of the maximum time interval.

In some scenarios, each maximum time interval includes two minimum time intervals as an example: a minimum time interval can be one cycle. If the target proxy device detects the reporting message in the first cycle, it will send the third time interval to the subscribing device. A notification message. If no reported message is detected in the second cycle, no message will be sent to the subscribing device. If a reported message is detected in the third cycle, the first notification message will be sent to the subscribing device. If in the third cycle, the first notification message will be sent to the subscribing device. If no reported message is detected within three cycles, a second notification message is sent to the subscribing device.

In still some embodiments, the first subscription request includes a minimum time interval and a maximum time interval, and the target proxy device may determine a time interval from the minimum time interval and the maximum time interval to send the predetermined notification message. Optionally, the target proxy device may determine the time interval based on the preconfiguration, or the target proxy device may determine the time interval based on business busyness and/or the computing capability of the target proxy device. Optionally, the time interval determined by the target proxy device may or may not be notified to the subscribing device.

The reporting message may be a message sent by any one or more target node devices to the target proxy device, and the reporting message may include updated content of target resources in one or more of the target node devices.
