Abstract: The present application belongs to the technical field of Internet of Things. Disclosed are a method for account association, and a computer device. The method is executed by a client device, and includes: obtaining an authorization code from an authorizing platform, and the authorizing platform is one of a first cloud platform and a second cloud platform, and the first cloud platform is a cloud platform to which the client device belongs; and sending the authorization code to an authorized platform, wherein the authorization code is configured for performing account association interaction between the authorized platform and the authorizing platform, such that a first account is associated with a second account. During the account association interaction process in the present solution, the capacity burden and the complexity of a client is reduced, and the efficiency of the development, update and maintenance of the client is improved.

Abstract: The embodiments of the present application provide a resource subscription method, a device, and a storage medium, a subscription device and a resource collection device respectively maintain a current tag of a subscription resource, where the tag of the subscription resource is generated according to a generation rule, tags generated according to the generation rule have an association relationship; during a resource update process, the subscription device may determine whether a version is missing according to the current tag of the subscription resource transmitted by the resource collection device, a tag of the subscription resource stored locally and the generation rule. Since one or more versions before a current version of the target resource are stored on the resource collection device, the subscription device may request a missing version from the resource collection device when a version is missing, thereby ensuring that the user will not miss the subscription resource.

Abstract: The present application provides an information transmission method and an electronic device. The method includes: receiving resource change information from a server, wherein the resource change information is used to indicate a change of a first element in a first attribute, the first attribute is an attribute in a form of an array, and the first element is an element of the first attribute that has changed.

Abstract: A method and an apparatus for device upgrade control, a computer device, and a storage medium are provided in the disclosure, which belongs to the field of internet of things (IoT) technology. The method includes: receiving a notification message sent by a first device, the notification message containing latest version information of the client device, and the first device including at least one of the client device and a second cloud platform; acquiring current version information of the client device; and sending an upgrade message to the client device when a version corresponding to the latest version information is higher than a version corresponding to the current version information, the upgrade message being used for triggering the client device to perform version upgrade.

Abstract: Provided are a control method, comprising: when establishing a first binding relationship with a first account number, a CHIP device meeting an original binding relationship release condition, releasing the first binding relationship, and establishing a second binding relationship with a second account number, such that a second configuration device using the second account configures the CHIP device. Further provided are another control method, a device, and a storage medium.

Abstract: Provided by the present disclosure are an Internet of Things communication method and apparatus. The method comprises: sending subscription information to a server, wherein the subscription information is used to request a subscription to a target resource on the server; receiving subscription response information sent by the server, wherein the subscription response information is used to characterize that a client successfully subscribes to the target resource, and the subscription response information comprises a validity period of the current state of the target resource; and once the validity period of the current state of the target resource expires, resending the subscription information of the target resource to the server.

Abstract: The present disclosure provides an Internet of Things communication method and apparatus. The method includes: receiving a resource addition request transmitted by a client, where the resource addition request is used to indicate addition of an identification of a reference resource into a collection resource on the first server; performing communication with the reference resource according to an access location of the reference resource and the identification of the reference resource; adding the identification of the reference resource into the collection resource if the communication between the first server and the reference resource is successful.

Abstract: Provided is a method for discovering security information. A first device sends a broadcast or multicast message to M second devices in a network where the first device is located, M is an integer greater than or equal to 1, and the broadcast or multicast message contains a request for performing security domain discovery; the first device receives representations of security domain resources fed back by N second devices, wherein N is an integer greater than or equal to 1 and less than or equal to M; the first device obtains L pieces of security domain information on the basis of the representations of the security domain resources fed back by the N second devices, and displays the L pieces of security domain information, L is an integer greater than or equal to 1, and the security domain information comprises a security domain identification (ID) and a security domain name.

Abstract: The embodiments of the present application provide a resource subscription method, a device, and a storage medium, a subscription device and a resource collection device respectively maintain a current tag of a subscription resource, where the tag of the subscription resource is generated according to a generation rule, tags generated according to the generation rule have an association relationship; during a resource update process, the subscription device may determine whether a version is missing according to the current tag of the subscription resource transmitted by the resource collection device, a tag of the subscription resource stored locally and the generation rule. Since one or more versions before a current version of the target resource are stored on the resource collection device, the subscription device may request a missing version from the resource collection device when a version is missing, thereby ensuring that the user will not miss the subscription resource.
