The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present invention.

在对本发明实施例提供的影子设备的生成方法进行详细说明之前，先对相关技术中终端设备向网络设备上报信息进行简要说明。Before describing in detail the method for generating the shadow device provided by the embodiment of the present invention, a brief description of the information reported by the terminal device to the network device in the related technology is firstly described.

在对本发明实施例提供的影子设备的生成方法进行详细说明之前，先对本发明实施例涉及的名词进行简要说明。Before describing in detail the method for generating a shadow device provided by the embodiment of the present invention, a brief description of the terms involved in the embodiment of the present invention will be given.

1)配置器，为服务端设备提供云服务器接入配置功能的工具，配置器的功能可以由应用软件实现。1) The configurator provides a tool for the server equipment to access the configuration function of the cloud server. The function of the configurator can be implemented by application software.

2)资源链接，表示OCF资源之间的引用关系。2) Resource link, indicating the reference relationship between OCF resources.

Other devices can directly communicate with the shadow device, thereby reducing the workload of message processing on the server device and improving the communication efficiency of the system.

6)资源目录，支持OCF设备发布资源和发现资源的逻辑功能实体。6) Resource catalog, supporting OCF equipment to publish resources and discover the logical functional entities of resources.

再对OCF设备以及OCF设备之间的通信进行简要说明。Then briefly explain the OCF equipment and the communication between OCF equipment.

OCF是新兴的物联网应用层技术标准组织，OCF为物联网设备之间实现互联互通制定Restful服务框架；在OCF Restful服务框架中，通过资源来表述物联网设备、OCF设备的功能服务和OCF 设备的状态等信息。其中，提供资源的实体是OCF服务端设备(以下简称服务端设备)，访问资源的实体是OCF客户端(以下简称客户端设备)。OCF is an emerging technology standards organization for the application layer of the Internet of Things. OCF develops a Restful service framework for interconnection and intercommunication between Internet of Things devices; in the OCF Restful service framework, resources are used to express Internet of Things devices, functional services of OCF devices, and OCF devices The status and other information. Among them, the entity that provides the resource is the OCF server device (hereinafter referred to as the server device), and the entity that accesses the resource is the OCF client (hereinafter referred to as the client device).

例如，获取室内环境状态数据的控制终端是客户端设备，监测室内环境状态数据的传感器设备是服务端设备，客户端设备和服务端设备的业务交互是通过对资源的创建、读取、更新、删除或者通知等资源操作方法而实现。For example, the control terminal that obtains the indoor environment status data is the client device, and the sensor device that monitors the indoor environment status data is the server device. The business interaction between the client device and the server device is through the creation, reading, and updating of resources. It is realized by resource operation methods such as deletion or notification.

客户端设备和服务端设备通信的流程，如图1所示：客户端设备向服务端设备发送针对服务端设备上的资源的更新资源请求。服务端设备根据所述更新资源请求，执行相应的资源操作，并向客户端设备发送更新资源响应；其中，所述更新资源响应中携带资源的表述。The communication process between the client device and the server device is shown in Figure 1: The client device sends a resource update request for resources on the server device to the server device. The server device performs a corresponding resource operation according to the update resource request, and sends an update resource response to the client device; wherein the update resource response carries a resource expression.

可选实施例中，资源更新请求的形式为：In an optional embodiment, the form of the resource update request is:

相应的，更新资源响应的形式为：Correspondingly, the form of the update resource response is:

这里，所述更新资源请求中携带资源的统一资源标识符(Uniform Resource Identifier，URI)以及资源操作方法；以图1为例，服务端设备上具有环境温度资源，资源的URI为“/environmentTemperature”；客户端设备向服务端设备请求的资源操作方法是更新方法POST。Here, the resource update request carries the Uniform Resource Identifier (URI) of the resource and the resource operation method; taking Figure 1 as an example, the server device has an environmental temperature resource, and the URI of the resource is "/environmentTemperature" ; The resource operation method requested by the client device from the server device is the update method POST.

资源的表述包括：资源的URI、资源类型、资源接口和资源的功能属性等，下面对资源的表述所包括的信息分别进行说明：The description of the resource includes: the URI of the resource, the resource type, the resource interface, and the functional attributes of the resource, etc. The information included in the description of the resource is described below:

资源的URI，在资源的表述中用“href”表示，提供OCF服务端设备资源的地址，“href”的值是具体的资源的URI，OCF客户端设备通过资源的URI来访问OCF服务端设备的资源；在图1中环境温度资源的URI是“/environmentTemperature”。The URI of the resource, represented by "href" in the description of the resource, provides the address of the OCF server device resource. The value of "href" is the URI of the specific resource. The OCF client device accesses the OCF server device through the resource URI. The resource; in Figure 1, the URI of the environmental temperature resource is "/environmentTemperature".

资源类型，在资源的表述中用“rt”表示，表示资源的类型，在图1中资源类型“rt”是“oic.r.temperature”，表示温度资源类型。The resource type, represented by "rt" in the description of the resource, represents the type of resource. In Figure 1, the resource type "rt" is "oic.r.temperature", which represents the temperature resource type.

资源接口，在资源的表述中用“if”表示，提供对资源的查看以及资源支持的响应，在图1中资源接口“if”是“oic.if.a”，表示控制器接口。The resource interface, represented by "if" in the description of the resource, provides a response to the resource view and resource support. In Figure 1, the resource interface "if" is "oic.if.a", which means the controller interface.

资源属性，在资源的表述中描述资源的属性信息，在图1中“targetTemperature”表示温度资源的目标温度属性，“currentTemperature”表示温度资源的当前温度属性，“temperatureRange”表示温度资源的温度范围属性。Resource attribute, describe the attribute information of the resource in the description of the resource. In Figure 1, "targetTemperature" represents the target temperature attribute of the temperature resource, "currentTemperature" represents the current temperature attribute of the temperature resource, and "temperatureRange" represents the temperature range attribute of the temperature resource .

OCF定义了所有OCF设备都必须支持的资源发现资源“/oic/res”，资源发现资源用于OCF设备以及资源的发现；资源发现资源提供设备资源发现的功能，资源发现资源的URI固定为“/oic/res”。OCF defines the resource discovery resource "/oic/res" that all OCF devices must support. Resource discovery resources are used for OCF device and resource discovery; resource discovery resources provide device resource discovery functions, and the URI of resource discovery resources is fixed as " /oic/res".

为表示资源之间的关联关系，OCF定义了资源链接，即资源Links；OCF服务端设备可以以资源链接的形式提供自己所拥有的资源，便于OCF客户端设备发现OCF服务端设备的资源。其中，资源链接的内容如下所示：In order to express the association relationship between resources, OCF defines resource links, namely resource Links; OCF server devices can provide their own resources in the form of resource links, so that OCF client devices can discover the resources of OCF server devices. Among them, the content of the resource link is as follows:

资源链接的内容包括：The content of the resource link includes:

anchor:上下文URI，表示包含资源链接的属主资源的URI。anchor: Context URI, which represents the URI of the owner resource that contains the resource link.

href:目标URI，即资源链接中引用的目标资源的URI。href: Target URI, that is, the URI of the target resource referenced in the resource link.

rt:目标资源的资源类型标识。rt: The resource type identifier of the target resource.

if:目标资源支持的接口。if: The interface supported by the target resource.

eps:可以访问目标资源的端点。eps: The endpoint that can access the target resource.

由于OCF标准协议在传输层采用受限制的应用协议(Constrained Application Protocol，CoAP)承载OCF消息，每个OCF服务端设备需要具有端点，每一个OCF设备必须关联至少一个端点用于发送和接收消息；客户端设备通过端点可以访问服务端设备的目标资源。在资源链接的参数中用“eps”数组表示目标资源的端点，具体端点用“ep”表示，即可以通过"eps"参数中"ep"值的地址访问目标资源。例如上面资源链接的例子中，客户端设备可以通过消息端点"coaps://[2001:db8:b::c2e5]:22222"访问目标资源"/myLightSwitch"。Since the OCF standard protocol adopts a restricted application protocol (CoAP) at the transport layer to carry OCF messages, each OCF server device needs to have an endpoint, and each OCF device must be associated with at least one endpoint for sending and receiving messages; The client device can access the target resource of the server device through the endpoint. The "eps" array is used in the resource link parameters to represent the endpoint of the target resource, and the specific endpoint is represented by "ep", that is, the target resource can be accessed through the address of the "ep" value in the "eps" parameter. For example, in the above resource link example, the client device can access the target resource "/myLightSwitch" through the message endpoint "coaps://[2001:db8:b::c2e5]:22222".

对于一些特定的场景，例如不需要频繁更新状态的IoT设备，客户端设备通过和服务端设备的影子设备通信，可以提高***通信效率。OCF云服务器实现影子服务，OCF云服务的影子服务为每个OCF服务端设备创建一个影子设备，影子设备可以直接响应客户端设备的请求，而无需获取服务端设备的资源表述；通过这种方式客户端设备不需要和服务端设备通信就可以获取服务端设备的资源表述，从而减轻服务端设备上的消息处理工作量，提高***的通信效率。For some specific scenarios, such as IoT devices that do not need to update their status frequently, the client device communicates with the shadow device of the server device, which can improve the communication efficiency of the system. OCF cloud server implements shadow service. The shadow service of OCF cloud service creates a shadow device for each OCF server device. The shadow device can directly respond to the request of the client device without obtaining the resource representation of the server device; in this way The client device does not need to communicate with the server device to obtain the resource representation of the server device, thereby reducing the workload of message processing on the server device and improving the communication efficiency of the system.

相关技术中，为服务端设备创建影子设备，以及服务端设备与影子设备的同步过程如图2所示，包括以下步骤：In the related technology, the creation of a shadow device for the server device and the synchronization process between the server device and the shadow device are shown in Figure 2, including the following steps:

1、配置器配置服务端设备：配置器为服务端设备执行影子配置过程，向服务端设备的影子配置资源发送资源更新请求，为服务端设备生成影子设备提供影子服务信息；其中。影子服务信息包括：影子服务标识、影子生成资源的URI、生成影子设备的指示；其中，影子服务标识表示影子服务的标识信息，影子生成资源的URI提供访问影子生成资源“oic.wk.shadow.gen”的URI(例如影子生成资源的URI是/oic/shadow/gen)，生成影子设备的指示用于指示原始设备是否生成影子设备。1. The configurator configures the server device: the configurator executes the shadow configuration process for the server device, sends a resource update request to the shadow configuration resource of the server device, and provides shadow service information for the server device to generate the shadow device; among them. The shadow service information includes: the shadow service identifier, the URI of the shadow generation resource, and the instructions for generating the shadow device; among them, the shadow service identifier represents the identification information of the shadow service, and the URI of the shadow generation resource provides access to the shadow generation resource "oic.wk.shadow. The URI of "gen" (for example, the URI of the shadow generation resource is /oic/shadow/gen), and the instruction for generating a shadow device is used to indicate whether the original device generates a shadow device.

2、为服务端设备生成影子设备：通过第1步服务端设备获得了影子服务信息，其中包括影子生成资源的URI，服务端设备针对影子生成资源的URI向云服务器发送创建影子设备的请求，请求中提供需要复制的原始资源信息；云服务器接收服务端设备的请求后，为服务端设备生成影子设备；其中，影子设备包括与原始资源信息对应的复制资源信息。2. Generate a shadow device for the server device: Through step 1, the server device obtains the shadow service information, which includes the URI of the shadow generation resource. The server device sends a request for creating the shadow device to the cloud server for the URI of the shadow generation resource. The request provides the original resource information that needs to be copied; after receiving the request from the server device, the cloud server generates a shadow device for the server device; where the shadow device includes the copied resource information corresponding to the original resource information.

3、配置器配置影子设备：配置器为影子设备执行配置过程，影子设备获取访问控制信息。3. The configurator configures the shadow device: the configurator executes the configuration process for the shadow device, and the shadow device obtains access control information.

4、云服务器收到资源更新请求：云服务器接收到客户端设备针对影子设备上复制资源的更新请求。4. The cloud server receives the resource update request: the cloud server receives the update request from the client device for the resources copied on the shadow device.

5、影子设备和服务端设备同步资源：服务端设备和影子设备通过影子同步资源建立同步关系，服务端设备和影子设备进行信息同步。5. The shadow device and the server device synchronize resources: the server device and the shadow device establish a synchronization relationship through the shadow synchronization resource, and the server device and the shadow device synchronize information.

6、影子设备向客户端设备发送同步信息。6. The shadow device sends synchronization information to the client device.

可以看出，图2所示的影子设备生成过程中，需要配置器多次与服务端设备、云服务器交互，导致生成影子设备的流程复杂。并且，在影子设备生成的过程中，需要用户选择复制到影子设备上的资源；如果用户选择的资源不合适，例如选了安全资源(安全资源是指安全通信相关的资源)，或者选择的功能资源(功能资源是指设备功能相关的资源，例如空调的温度设置资源)不全面，选中的功能资源会通过影子设备同步，未被选中的功能资源则不能通过影子设备同步；如此，会造成生成的影子设备不能准确的复制原始设备的功能，进而影响影子设备的功能。It can be seen that in the shadow device generation process shown in FIG. 2, the configurator needs to interact with the server device and the cloud server multiple times, resulting in a complicated process of generating the shadow device. In addition, in the process of shadow device generation, the user needs to select the resources copied to the shadow device; if the resource selected by the user is inappropriate, for example, a secure resource is selected (secure resources refer to resources related to secure communication), or selected functions Resources (functional resources refer to resources related to device functions, such as air-conditioning temperature setting resources) are not comprehensive, selected functional resources will be synchronized through the shadow device, and unselected functional resources cannot be synchronized through the shadow device; this will cause generation The shadow device cannot accurately replicate the function of the original device, which affects the function of the shadow device.

基于上述问题，本发明提供一种影子设备的生成方法，本申请实施例的影子设备的生成方法可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***或5G***等。Based on the above problems, the present invention provides a method for generating shadow devices. The method for generating shadow devices in the embodiments of this application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, code Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) ) System, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability (Worldwide Interoperability) for Microwave Access, WiMAX) communication system or 5G system, etc.

举例来说，原始设备是空调，设备标识为dc70373c-1e8d-4fb3-962e-017eaa863989，空调实现了当前温度资源(资源URI为/currentTemperature)和目标温度资源(资源URI为/targetTemperature)两个功能资源，那么OCF云服务器生成的影子设备的设备标识也为 dc70373c-1e8d-4fb3-962e-017eaa863989，影子设备也具有当前温度资源(资源URI为/currentTemperature)和目标温度资源(资源URI为/targetTemperature)两个功能资源。生成的影子设备的资源表述见下：For example, the original device is an air conditioner, and the device identifier is dc70373c-1e8d-4fb3-962e-017eaa863989. The air conditioner implements two functional resources: the current temperature resource (resource URI is /currentTemperature) and the target temperature resource (resource URI is /targetTemperature) , Then the device identifier of the shadow device generated by the OCF cloud server is also dc70373c-1e8d-4fb3-962e-017eaa863989, and the shadow device also has a current temperature resource (resource URI is /currentTemperature) and a target temperature resource (resource URI is /targetTemperature).

可选的，资源目录公布的影子资源的URI加上OCF设备的设备标识。Optionally, the URI of the shadow resource published in the resource catalog plus the device identifier of the OCF device.

举例来说，OCF设备的设备标识为dc70373c-1e8d-4fb3-962e-017eaa863989，发布到资源目录的影子设备的当前温度资源的资源URI为/currentTemperature，目标温度资源的资源URI为/targetTemperature，则资源目录公布的影子设备的当前温度资源URI为dc70373c-1e8d-4fb3-962e-017eaa863989/currentTemperature，目标温度资源的资源URI为dc70373c-1e8d-4fb3-962e-017eaa863989/targetTemperature。For example, the device identifier of the OCF device is dc70373c-1e8d-4fb3-962e-017eaa863989, the resource URI of the current temperature resource of the shadow device published to the resource catalog is /currentTemperature, and the resource URI of the target temperature resource is /targetTemperature, then the resource The current temperature resource URI of the shadow device published in the catalog is dc70373c-1e8d-4fb3-962e-017eaa863989/currentTemperature, and the resource URI of the target temperature resource is dc70373c-1e8d-4fb3-962e-017eaa863989/targetTemperature.

步骤S406，OCF服务端设备上的资源表述发生变化，需要进行资源同步。In step S406, the resource expression on the OCF server device changes, and resource synchronization needs to be performed.

举例来说，OCF服务端设备是空调，具有监测当前温度的功能，实现了/currentTemperature资源，监测到的当前温度发生变化，/currentTemperature资源的温度值发生了变化，当前温度值value变为28℃，需要同步给影子设备。For example, the OCF server equipment is an air conditioner, which has the function of monitoring the current temperature, and realizes the /currentTemperature resource.

举例来说，OCF设备的当前温度资源/currentTemperature发生变化，当前温度值value变为28℃，则请求同步的影子设备的目标资源URI为/currentTemperature，请求消息中提供的资源表述见下：For example, if the current temperature resource /currentTemperature of the OCF device changes, and the current temperature value becomes 28°C, the target resource URI of the shadow device requesting synchronization is /currentTemperature. The resource expression provided in the request message is as follows:

其中，"di"是空调的设备标识，"resources"是发生变化的空调的当前温度资源的资源表述。Among them, "di" is the equipment identification of the air conditioner, and "resources" is the resource expression of the current temperature resource of the changed air conditioner.

步骤S409、OCF云服务器上的影子设备向OCF服务端设备发送资源同步响应。Step S409: The shadow device on the OCF cloud server sends a resource synchronization response to the OCF server device.

需要说明的是，步骤S406至步骤S409为上行资源同步过程，即OCF服务端设备向OCF云服务器上的影子设备进行资源同步的过程。It should be noted that steps S406 to S409 are the uplink resource synchronization process, that is, the process of resource synchronization between the OCF server device and the shadow device on the OCF cloud server.

步骤S410，OCF客户端设备通过OCF云服务器发现影子设备的资源。Step S410, the OCF client device discovers the resource of the shadow device through the OCF cloud server.

举例来说，OCF客户端设备获取影子设备的目标温度资源dc70373c-1e8d-4fb3-962e-017eaa863989/targetTemperature的资源表述，得到目标温度为25℃。For example, the OCF client device obtains the resource representation of the target temperature resource dc70373c-1e8d-4fb3-962e-017eaa863989/targetTemperature of the shadow device, and obtains the target temperature as 25°C.

步骤S413，OCF客户端设备请求更新影子设备的资源表述。Step S413, the OCF client device requests to update the resource representation of the shadow device.

举例来说，OCF客户端设备请求更新影子设备的目标温度资源dc70373c-1e8d-4fb3-962e-017eaa863989/targetTemperature的资源表述，请求更新的目标温度为20℃。For example, the OCF client device requests to update the resource representation of the target temperature resource dc70373c-1e8d-4fb3-962e-017eaa863989/targetTemperature of the shadow device, and the target temperature requested to update is 20°C.

步骤S414、OCF云服务器的影子设备请求向OCF服务端设备进行资源同步，请求资源同步的目标资源URI是需要更新资源表述的原始资源URI。Step S414: The shadow device of the OCF cloud server requests resource synchronization to the OCF server device, and the target resource URI of the requested resource synchronization is the original resource URI whose resource expression needs to be updated.

可选的，OCF云服务器的影子设备将目标资源URI中的设备标识去掉，再向OCF服务端设备发送资源同步请求。Optionally, the shadow device of the OCF cloud server removes the device identifier in the target resource URI, and then sends a resource synchronization request to the OCF server device.

步骤S517，OCF云服务器上的影子设备向OCF客户端设备发送设备资源表述的更新结果。Step S517: The shadow device on the OCF cloud server sends the update result of the device resource expression to the OCF client device.

需要说明的是，步骤S510至步骤S517为下行资源同步过程，即OCF云服务器上的影子设备向OCF服务端设备进行资源同步的过程。It should be noted that steps S510 to S517 are the downlink resource synchronization process, that is, the process of resource synchronization between the shadow device on the OCF cloud server and the OCF server device.

针对图7和图8所示的影子设备的生成方法，本发明实施例提供的又一种影子设备的生成方法的详细处理流程，如图9所示，包括以下步骤：With regard to the shadow device generation methods shown in FIGS. 7 and 8, the detailed processing flow of another shadow device generation method provided by the embodiment of the present invention, as shown in FIG. 9, includes the following steps:

步骤S801，OCF服务端设备连接到OCF云服务器。In step S801, the OCF server device is connected to the OCF cloud server.

步骤S802-步骤S804，OCF服务端设备向OCF云服务器发布自己的资源链接，OCF云服务器将影子设备的资源链接发布到OCF云服务器的资源目录。Step S802-Step S804, the OCF server device publishes its own resource link to the OCF cloud server, and the OCF cloud server publishes the resource link of the shadow device to the resource catalog of the OCF cloud server.

举例来说，OCF服务端设备是空调，设备标识为dc70373c-1e8d-4fb3-962e-017eaa863989，空调具有当前温度资源(资源URI为/currentTemperature，当前温度值value为25℃)和目标温度资源(资源URI为/targetTemperature，目标温度值value为25℃)两个功能资源。For example, the OCF server device is an air conditioner, and the device ID is dc70373c-1e8d-4fb3-962e-017eaa863989. The air conditioner has a current temperature resource (the resource URI is /currentTemperature, and the current temperature value is 25°C) and a target temperature resource (resource The URI is /targetTemperature, and the target temperature value is 25°C) two functional resources.

请求发布资源的目标资源URI为/oic/rd，请求消息中提供的资源链接见下：The target resource URI of the requested publishing resource is /oic/rd, and the resource link provided in the request message is as follows:

其中，"di"是空调的设备标识，"resources"是空调的资源链接，包括当前温度资源和目标温度资源的资源链接。Among them, "di" is the equipment identification of the air conditioner, and "resources" is the resource link of the air conditioner, including the resource link of the current temperature resource and the target temperature resource.

OCF服务端设备将资源链接发布到OCF云服务器后，OCF云服务器需要获取OCF服务端设备的资源表述，用于生成对应的影子设备。OCF云服务器至少可通过下述两种方式获取OCF服务端设备的资源表述：After the OCF server device publishes the resource link to the OCF cloud server, the OCF cloud server needs to obtain the resource representation of the OCF server device to generate the corresponding shadow device. The OCF cloud server can obtain the resource representation of the OCF server device in at least the following two ways:

方式a：OCF服务端设备分别针对每个发布的资源单独获取资源表述；如果OCF服务端设备发布了N个资源链接，则OCF云服务器需要向OCF服务端设备发送N次获取资源表述的请求，用于获取每个资源的资源表述。Method a: The OCF server device separately obtains resource expressions for each published resource; if the OCF server device publishes N resource links, the OCF cloud server needs to send N requests for obtaining resource expressions to the OCF server device. The resource representation used to obtain each resource.

步骤S805a-步骤S806a，根据OCF服务端设备发布的资源链接，OCF云服务器分别向每个发布的资源发送获取资源表述的请求。In step S805a-step S806a, according to the resource link published by the OCF server device, the OCF cloud server sends a request for obtaining a resource expression to each published resource.

举例来说，OCF服务端设备发布的资源链接包括当前温度资源/currentTemperature和目标温度资源/currentTemperature，则OCF云服务器分别针对这两个资源发送获取资源表述的请求，从而获取到所有已发布到OCF云服务器的资源的资源表述。For example, if the resource links published by the OCF server device include current temperature resource/currentTemperature and target temperature resource/currentTemperature, the OCF cloud server sends requests to obtain resource expressions for these two resources, thereby obtaining all the resources that have been published to OCF. The resource representation of the resource of the cloud server.

方式b：通过批量获取资源表述的方式来获取OCF服务端设备发布到OCF云服务器的所有资源的资源表述；这种情况下，OCF云服务器只需要向OCF服务端设备发送1个获取资源表述的请求，就可以获取该OCF服务端设备发布到OCF云服务器的所有资源的资源表述。Method b: Obtain the resource expressions of all the resources published by the OCF server device to the OCF cloud server by obtaining resource expressions in batches; in this case, the OCF cloud server only needs to send one resource expression acquisition to the OCF server device Upon request, it is possible to obtain the resource expressions of all resources published by the OCF server device to the OCF cloud server.

步骤S805b-步骤S806b，OCF云服务器向OCF服务端设备发送批量获取资源表述的请求，获取该OCF服务端设备发布到OCF云服务器的所有资源的资源表述。In step S805b-step S806b, the OCF cloud server sends a batch request for obtaining resource expressions to the OCF server device, and obtains the resource expressions of all resources published by the OCF server device to the OCF cloud server.

举例来说，批量获取OCF设备资源表述的资源URI为/fullStatusQuery，则OCF云服务器针对该资源URI发送获取资源表述的请求，从而获取到所有已发布到OCF云服务器的资源的资源表述。For example, if the resource URI for obtaining OCF device resource expressions in batches is /fullStatusQuery, the OCF cloud server sends a request for obtaining resource expressions for the resource URI, thereby obtaining the resource expressions of all resources that have been published to the OCF cloud server.

步骤S807、OCF云服务器为OCF服务端设备生成影子设备，生成的影子设备的复制资源URI和OCF服务端设备的原始设备的影子资源URI相同。Step S807: The OCF cloud server generates a shadow device for the OCF server device, and the generated copy resource URI of the shadow device is the same as the shadow resource URI of the original device of the OCF server device.

这里，影子设备的设备标识可以和OCF服务端设备(即原始设备)的设备标识相同，也可以不同。Here, the device ID of the shadow device can be the same as or different from the device ID of the OCF server device (ie, the original device).

举例来说，原始设备是空调，空调具有当前温度资源(资源URI为/currentTemperature)和目标温度资源(资源URI为/targetTemperature)两个功能资源，当前温度值value为25℃，目标温度值value为25℃，那么OCF云服务器生成的影子设备也具有当前温度资源(资源URI为/currentTemperature，当前温度值value为25℃)和目标温度资源(资源URI为/targetTemperature，目标温度值value为25℃)两个功能资源。生成的影子设备的资源表述见下：For example, the original equipment is an air conditioner. The air conditioner has two functional resources: the current temperature resource (resource URI is /currentTemperature) and the target temperature resource (resource URI is /targetTemperature). The current temperature value is 25°C, and the target temperature value is 25°C, the shadow device generated by the OCF cloud server also has current temperature resources (resource URI is /currentTemperature, current temperature value is 25°C) and target temperature resources (resource URI is /targetTemperature, target temperature value is 25°C) Two functional resources. The resource description of the generated shadow device is as follows:

其中，"di"是空调的影子设备的设备标识，该设备标识可以和空调自身的设备标识相同或不同，"resources"是空调的影子设备的资源表述，包括该影子设备当前温度资源和目标温度资源的资源表述。Among them, "di" is the device ID of the shadow device of the air conditioner, which can be the same as or different from the device ID of the air conditioner itself, and "resources" is the resource expression of the shadow device of the air conditioner, including the current temperature resource and target temperature of the shadow device Resource representation of resources.

步骤S808，生成影子设备后，OCF云服务器为生成的影子设备向OCF服务端设备订阅对应的原始设备的资源。Step S808: After the shadow device is generated, the OCF cloud server subscribes the resources of the corresponding original device to the OCF server device for the generated shadow device.

举例来说，OCF云服务器为OCF服务端设备生成的影子设备具有当前温度资源(资源URI为/currentTemperature)和目标温度资源(资源URI为/targetTemperature)两个功能资源，则OCF云服务器向OCF服务端设备的当前温度资源(资源URI为/currentTemperature)和目标温度资源(资源URI为/targetTemperature)进行资源订阅，用于获取这两个原始资源的资源变化通知。For example, if the shadow device generated by the OCF cloud server for the OCF server device has two functional resources, the current temperature resource (resource URI is /currentTemperature) and the target temperature resource (resource URI is /targetTemperature), then the OCF cloud server serves the OCF The current temperature resource (resource URI: /currentTemperature) and the target temperature resource (resource URI: /targetTemperature) of the end device perform resource subscription to obtain resource change notifications of these two original resources.

步骤S809，OCF服务端设备上的资源表述发生变化，由于OCF云服务器订阅了该OCF服务端设备的资源，因此OCF服务端设备需要向OCF云服务器发送变化的资源表述。In step S809, the resource expression on the OCF server device changes. Since the OCF cloud server subscribes to the resource of the OCF server device, the OCF server device needs to send the changed resource expression to the OCF cloud server.

举例来说，OCF设备是空调，具有监测当前温度的功能，实现了/currentTemperature资源，监测到的当前温度发生变化，/currentTemperature资源的温度值发生了变化，当前温度值value变为28℃，需要将最新的温度值发送给OCF云服务器。For example, the OCF device is an air conditioner, which has the function of monitoring the current temperature. It realizes the /currentTemperature resource. The monitored current temperature changes, and the temperature value of the /currentTemperature resource changes, and the current temperature value becomes 28°C. Send the latest temperature value to the OCF cloud server.

步骤S810，OCF服务端设备向OCF云服务器发送资源更新通知同步，提供发生变化的资源的资源表述。In step S810, the OCF server device sends a resource update notification synchronization to the OCF cloud server, and provides a resource expression of the changed resource.

举例来说，OCF服务端设备的当前温度资源/currentTemperature发生变化，当前温度值value变为28℃，则OCF设备将当前温度资源的最新资源表述发送给OCF云服务器，请求消息中提供的资源表述见下：For example, if the current temperature resource/currentTemperature of the OCF server device changes, and the current temperature value becomes 28°C, the OCF device sends the latest resource expression of the current temperature resource to the OCF cloud server, requesting the resource expression provided in the message See below:

{{

"value":28,"value":28,

"unit":"℃""unit":"℃"

}}

步骤S811、OCF云服务器将更新的资源表述复制到影子设备上。Step S811: The OCF cloud server copies the updated resource expression to the shadow device.

举例来说，根据步骤S810中的OCF服务端设备提供的当前温度资源更新的资源表述，OCF云服务器上的影子设备的当前温度资源/currentTemperature的当前温度值value更新为28℃。For example, according to the resource expression of the current temperature resource update provided by the OCF server device in step S810, the current temperature resource of the shadow device on the OCF cloud server/current temperature value value of currentTemperature is updated to 28°C.

需要说明的是，步骤S809至步骤S811为上行资源同步过程，即OCF服务端设备向OCF云服务器上的影子设备进行资源同步的过程。It should be noted that steps S809 to S811 are the uplink resource synchronization process, that is, the process of resource synchronization between the OCF server device and the shadow device on the OCF cloud server.

步骤S812-步骤S815，OCF客户端设备发现并获取影子设备的资源表述。Step S812-Step S815, the OCF client device discovers and obtains the resource representation of the shadow device.

步骤S816，OCF云服务器请求更新OCF服务端设备的资源表述，请求更新的目标资源URI是需要更新资源表述的OCF服务端设备的资源URI。In step S816, the OCF cloud server requests to update the resource expression of the OCF server device, and the target resource URI requested to update is the resource URI of the OCF server device that needs to update the resource expression.

可选的，OCF云服务器将目标资源URI中的设备标识去掉，再向OCF设备发送资源更新请求。Optionally, the OCF cloud server removes the device identifier in the target resource URI, and then sends a resource update request to the OCF device.

举例来说，OCF云服务器收到的OCF客户端设备请求更新的目标温度资源dc70373c-1e8d-4fb3-962e-017eaa863989/targetTemperature，请求更新的目标温度值value为20℃，则OCF云服务器将目标资源URI中的设备标识dc70373c-1e8d-4fb3-962e-017eaa863989去掉，请求更新的原始设备的目标资源URI为目标温度资源/targetTemperature，请求消息中提供的资源表述见下：For example, if the OCF client device receives the target temperature resource dc70373c-1e8d-4fb3-962e-017eaa863989/targetTemperature received by the OCF cloud server, and the target temperature value requested to be updated is 20°C, the OCF cloud server sets the target resource The device identifier dc70373c-1e8d-4fb3-962e-017eaa863989 in the URI is removed, and the target resource URI of the original device requesting the update is the target temperature resource/targetTemperature. The resource description provided in the request message is as follows:

{{

"value":20,"value":20,
