The described embodiments are only some embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings. The embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be understood that "system", "apparatus", "unit" and/or "module" as used herein is a method for distinguishing different components, elements, parts or assemblies at different levels. However, other words may be substituted by other expressions if they accomplish the same purpose.
As used in this application and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements.

Different cloud service platforms operate independently, so that natural barriers exist among the cloud service platforms, for example, the cloud service platforms have different network access protocols, different communication protocols, different protocol field conventions, different equipment management modes and the like. This results in that the terminal device cannot be used universally between different cloud service platforms, and further the terminal device manufacturer needs to research and develop the terminal device for different cloud platforms, which directly increases the research and development costs and the manufacturing costs of the device manufacturer. Or the firmware for butting different cloud platforms is packaged into the terminal equipment together. In this case, the terminal device is required to provide support of a larger storage space, which increases hardware cost. In addition, when a plurality of pieces of firmware are packaged into one piece of firmware, it is difficult to maintain the version of the firmware, and it is difficult to upgrade the device code. For a user, if a terminal equipment product in a certain ecological state is purchased, the terminal equipment product can only be used in the corresponding ecological state, so that platform service is inconvenient to replace.
In order to solve the above problem, the present application provides a method and an apparatus for accessing a cloud platform.
Fig. 1 illustrates an exemplary system architecture 100 to which some embodiments of the present methods for accessing a cloud platform or apparatuses for accessing a cloud platform may be applied.
As shown in fig. 1, the system architecture 100 may include a gateway device 101, a server 102, cloud platforms 103, 104, 105, and terminal devices 106 and 107. The media between the gateway device 101, the server 102, the cloud platform 103, and the terminal device 104 may provide communication links through a network (not shown in the figure). The network may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.

The gateway device 101 may be configured to, according to the protocol mapping relationship issued by the server 102, relay a message based on the own protocol of the gateway device to a message based on the cloud platform protocol, and upload the message to the cloud platform, or relay a message based on the cloud platform protocol to a message based on the own protocol, and issue the message to the terminal device under the gateway device 101.
The server 102 may be a server that provides various services, for example, a cloud platform that records and maintains the gateway device 101 and the terminal device 104 under the gateway device 101 and needs to be docked, a server that maintains a mapping relationship between a cloud platform protocol and a gateway device protocol, and a server that provides a load balancing service. The server 102 may issue the protocol mapping relationship between the gateway device and the cloud platform to the gateway device when the gateway accesses the network. In addition, server 102 may also provide Over-the-Air (OTA) functionality for gateway device 101 to upgrade firmware performed by the gateway device if needed.
The server may be hardware or software. When the server is hardware, it may be implemented as a distributed server cluster formed by multiple servers, or may be implemented as a single server. When the server is software, it may be implemented as a plurality of software or software modules, or may be implemented as a single software or software module. And is not particularly limited herein.
The cloud platform 103 may be a service network providing various services, and may include, for example and without limitation, a platform providing internet of things for providing services such as access, function mapping, scene linkage, and the like of terminal devices. The service network may be hardware or software. When the service network is hardware, it may be implemented as a distributed server cluster composed of multiple servers, or may be implemented as a single server. When the services network is software, it may be implemented as a plurality of software or software modules (for example, to provide distributed services), or as a single software or software module. And is not particularly limited herein.
The terminal device 104 may be hardware or software. When the terminal device 104 is hardware, it may be various electronic devices, including but not limited to electronic devices such as a smart phone, a tablet computer, a wearable device, and a smart home device. Smart home devices may include, for example, but are not limited to, smart meters, smart water meters, smart cats' eyes, smart locks, and the like. When the terminal device 104 is software, it can be installed in the electronic devices listed above. It may be implemented as a plurality of software or software modules (for example to provide distributed services) or as a single software or software module. The embodiment of the present application does not set any limit to the specific type of the electronic device.
It should be noted that the method for accessing the cloud platform provided in the embodiment of the present application is generally performed by the gateway device 101, and accordingly, the apparatus for accessing the cloud platform is generally disposed in the gateway device 101.
It should be understood that the number of gateway devices, servers, cloud platforms, and end devices in fig. 1 is merely illustrative. Any number of servers, cloud platforms, and terminal devices may be present, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for accessing a cloud platform in accordance with the present application is shown. The execution subject of the method for accessing the cloud platform may be, for example, the gateway device 101 shown in fig. 1. The method for accessing a cloud platform comprises the following steps 201 and 202.
In this embodiment, an execution subject (for example, the gateway device 101 shown in fig. 1) of the method for accessing the cloud platform may receive the protocol mapping relationship between the gateway device and the first cloud platform, which is sent by the server.
In the embodiment of the application, the server may store gateway device information, information of at least one cloud platform to which each terminal device under the gateway device is docked, and a protocol mapping relationship between the gateway device and the cloud platform.
In an embodiment of the present application, the protocol mapping relationship is a mapping relationship of a communication protocol between the cloud platform and the gateway device.
In one embodiment of the invention, the protocol mapping relationship may be implemented by a message mapping template. The message mapping template is used for describing the transformation constraint between the variables and parameters required by the communication protocol of the gateway device and the variables and parameters required by the communication protocol of the cloud platform.
In embodiments of the present application, when the gateway device is started (including but not limited to a power-back, a network terminal reconnection, etc.), it may communicate with the server. The server can issue the protocol mapping relation between the gateway equipment and the cloud platform to the gateway equipment. Of course, when the user has a need to change the gateway device or the cloud platform to which the terminal device under the gateway device is docked, for example, the user changes the protocol mapping relationship between the original gateway device and the cloud platform recorded in the server, at this time, the server may send the changed protocol mapping relationship to the gateway device. The condition for the trigger server to issue the protocol mapping relationship between the gateway device and the cloud platform is not limited in the present application.
In this embodiment, the executing agent may control data communication between the terminal device under the gateway device and the first cloud platform based on the first protocol mapping relationship sent by the server.
The data communication between the terminal device and the first cloud platform may be, for example, sending messages between the terminal device and the first cloud platform, and performing interaction to use various services provided by the first cloud platform. In the process, the first cloud platform can send downlink messages to the terminal device through the gateway device, and the terminal device can send uplink messages to the first cloud platform through the gateway device.
In the embodiment of the application, the gateway device may convert, based on the first protocol mapping relationship, the downlink message sent by the first cloud platform into a first message conforming to a communication protocol of the gateway device, and send the first message to the terminal device, so that the terminal device executes the first message. In addition, the gateway device may convert the downlink message sent by the terminal device into a message conforming to the communication protocol of the first cloud platform based on the first protocol mapping relationship, and send the message to the first cloud platform, so that the first cloud platform provides corresponding feedback based on the received message.
In some optional implementation manners of this embodiment, the gateway device may manage the terminal device under the gateway device, such as uplink and downlink protocol coding and decoding between the terminal device and the gateway device (e.g., protocol conversion between a terminal device private protocol and a gateway device private protocol). It should be noted that the same communication protocol may be used between the gateway device and each terminal device using the gateway device, or protocol conversion firmware between the gateway device and each terminal device is preset in the gateway device, so as to realize the conversion of messages between the gateway device and each terminal device. Therefore, on the premise that the protocol conversion between the terminal equipment and the gateway equipment is set, only the protocol conversion between the cloud platform and the gateway equipment needs to be considered, and then the access process of the terminal equipment under the gateway equipment to the platform is converted into the mapping process from the gateway equipment protocol to the cloud platform protocol.
In some optional implementations of this embodiment, the server is further configured to manage and maintain a white list of the terminal device. The white list indicates legal terminal devices that can access the corresponding cloud platform or gateway device. And then other terminal devices in the white list can maliciously access the corresponding cloud platform or gateway device.
In the method provided by the above embodiment of the application, the first protocol mapping relationship between the gateway device and the first cloud platform to be accessed, which is sent by the server, is received, and the data communication between the terminal device under the gateway device and the first cloud platform is controlled based on the protocol mapping relationship, so that when the gateway performs the up-and-down communication, a layer of conversion is added between the terminal device protocol and the cloud platform protocol, a protocol analysis part of the gateway device is abstracted into the service logic layer and the protocol mapping layer, and the process of accessing the platform by the terminal device under the gateway device is successfully converted into the process of mapping the gateway device protocol to the cloud platform protocol. By means of the mode that the server issues the protocol mapping relation, the effect that the gateway can access different cloud platforms by using the same firmware is achieved. In addition, the process that the terminal equipment is accessed to different cloud platforms is realized through the gateway equipment, and the whole research and development investment when the terminal equipment is suitable for being accessed to different cloud platforms is reduced.
With further reference to fig. 3, a flow 300 of yet another embodiment of a method for accessing a cloud platform is shown. The execution subject of the method for accessing the cloud platform may be, for example, the gateway device 101 shown in fig. 1. The method for accessing the cloud platform comprises the following steps 301-305.
In this embodiment, an executing subject (e.g., the gateway device 101 shown in fig. 1) of the method for accessing the cloud platform may authenticate the server when accessing the server.
In one embodiment of the present application, a gateway device may include a module to interface with a server. The module may then access the server and verify the identity of the server.
In some optional implementation manners of this embodiment, the gateway device encrypts its own data according to a manner agreed with the server, so as to ensure the security of its own data.
In this embodiment, the execution subject may receive and store the access information sent by the server to the first cloud platform when the server identity authentication passes.
In some embodiments of the present application, the access information of the cloud platform may include account information of the cloud platform, an access manner (such as a host address, a port, and the like), an identity authentication manner (such as a certificate, and the like), a platform category, configuration information of a platform access parameter, and the like.
The server records the gateway equipment and a cloud platform which is required to be in butt joint with the terminal equipment under the gateway equipment. When the gateway equipment accesses the network, the server can issue the access information required by the cloud platform access to the gateway.
The execution main body can store the access information after receiving the access information of the first cloud platform, and then can access the corresponding cloud platform according to the stored access information. In this way, even under the condition that the server cannot be accessed, the cloud platform can still be accessed according to the locally stored access information.
In this embodiment, the execution subject may access the first cloud platform according to the access information of the first cloud platform.
And 304, controlling data communication between the terminal equipment under the gateway equipment and the first cloud platform based on the first protocol mapping relation.
The step 302 for receiving the first protocol mapping relationship and the step 304 are the same as the step 201 and 202 in the embodiment shown in fig. 2, and are not described herein again.
In some optional implementation manners of this embodiment, after receiving the first protocol mapping relationship, the executing main push may perform security check on the first protocol mapping relationship according to a predetermined check method, and control data communication between the terminal device under the gateway device and the first cloud platform based on the first protocol mapping relationship after the check is successful. Therefore, the safety of the used protocol mapping relation can be ensured, and the data safety in the communication process of the terminal equipment and the cloud platform is further ensured.
As can be seen from fig. 3, compared with the embodiment corresponding to fig. 2, the process 300 of the method for accessing to the cloud platform in this embodiment highlights that the gateway device performs authentication on the server, receives and stores the access information of the first cloud platform and the first protocol mapping relationship, which are sent by the server after the authentication is passed, accesses to the cloud platform according to the access information of the first cloud platform, and controls data communication between the terminal device under the gateway device and the first cloud platform based on the first protocol mapping relationship. Therefore, the scheme described in this embodiment can ensure the security of the received access information of the cloud platform and the corresponding protocol mapping relationship through the authentication of the server, and prevent other servers from falsely sending malicious or false access information and protocol mapping relationship, thereby improving the security of the access and communication of the cloud platform.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for accessing a cloud platform is shown. The execution subject of the method for accessing the cloud platform may be, for example, the gateway device 101 shown in fig. 1. The method for accessing the cloud platform comprises the following steps 401 and 407.
Step 401 is the same as step 201 in the embodiment shown in fig. 2, and is not repeated here.
In this embodiment, an executing entity (for example, the gateway device 101 shown in fig. 1) of the method for accessing the cloud platform may receive the downlink message sent by the first cloud platform. The downlink message sent by the first cloud platform refers to a message sent by the first cloud platform to the terminal device. The downstream message is based on a first cloud platform communication protocol. The downstream message may include a message identification, a subject, a condition, a variable, a parameter, etc.
In this embodiment, the executing entity may convert the downlink message into a first message conforming to a communication protocol of the gateway device based on the first protocol mapping relationship.
In one embodiment of the invention, the protocol mapping relationship may be implemented by a message mapping template. The message mapping template is used for describing the transformation constraints between variables and parameters required by the communication protocol of the gateway device and the variables and parameters required by the communication protocol of the cloud platform.
After receiving the downlink message, the execution main body can determine the instruction type of the message according to the condition requirement in the message mapping template, then extract the parameters required by the self protocol of the gateway equipment from the downlink message according to the variables and the parameters in the template, and generate a first message according to the extracted parameters. The instruction category can be determined according to the service types of all messages in different application scenarios. Taking the smart lock as an example, the instruction type may include a password adding instruction, an unlocking instruction, and the like.
In this embodiment, the execution body may send the first message converted from the downlink message to the terminal device. When receiving the first message, the terminal device may execute a corresponding operation according to an instruction or operation in the first message.
Taking a gateway device accessed by an mqtt (message queue telemetry transport) protocol as an example, after the gateway device is accessed to a cloud platform through a network, the gateway device can subscribe to topic of a downlink message according to a topic (topic) list returned by a server. The gateway device receives a downlink message sent by the cloud platform, and matches an available mapping with a condition (condition) list in a protocol mapping relationship. And according to the retrieved mapping, converting the cloud platform protocol into the private communication protocol of the gateway equipment, and completing subsequent service logic according to the newly generated private protocol of the gateway equipment.
In this embodiment, the execution main body may receive an uplink message sent by the terminal device. The upstream message is based on a communication protocol of the gateway device. The upstream message may include a message identification, a subject, a condition, a variable, a parameter, etc.
The process of converting the uplink message into the second message conforming to the communication protocol of the first cloud platform is similar to the process of converting the downlink message into the first message conforming to the communication protocol of the gateway device, and is not described herein again.
In this embodiment, the execution body may send the second message converted from the uplink message to the first cloud platform. When receiving the second message, the first cloud platform may perform a corresponding operation according to an instruction or an operation in the second message, or provide a corresponding feedback.
Taking an mqtt message as an example, the gateway device processes the communication message from the terminal device and converts the communication message into a gateway device private protocol, and matches available mapping according to a condition list in a protocol mapping relationship, wherein the protocol mapping relationship comprises protocol information and a corresponding topic. And generating protocol content of the cloud platform according to the protocol mapping relation, and sending the generated protocol content to the cloud platform through the topic.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the process 400 of the method for accessing the cloud platform in this embodiment highlights that the downlink message sent by the cloud platform is converted into the first message conforming to the gateway device and then sent to the terminal device, and the uplink message sent by the terminal device is converted into the second message conforming to the cloud platform and then sent to the cloud platform. Therefore, in the scheme described in this embodiment, when the gateway performs uplink and downlink communication, a layer of conversion is added between the terminal device protocol and the cloud platform protocol, a protocol analysis part of the gateway device is abstracted into the service logic layer and the protocol mapping layer, and an access process of the terminal device to the platform under the gateway device is successfully converted into a mapping process from the gateway device protocol to the cloud platform protocol. In addition, the process that the terminal equipment is accessed to different cloud platforms is realized through the gateway equipment, and the whole research and development investment when the terminal equipment is suitable for being accessed to different cloud platforms is reduced.
With further reference to fig. 5, a flow 500 of yet another embodiment of a method for accessing a cloud platform is shown. The execution subject of the method for accessing the cloud platform may be, for example, the gateway device 101 shown in fig. 1. The method for accessing the cloud platform includes the following steps 501 and 504.
The steps 501 and 502 are the same as the step 201 and 202 in the embodiment shown in fig. 2, and are not described herein again.
In this embodiment, the execution agent may receive a platform change instruction sent by the server. When there is a cloud platform change demand, the maintenance personnel may provide the changed access information of the cloud platform (i.e., the second cloud platform) and the protocol mapping relationship between the cloud platform and the gateway device (i.e., the second protocol mapping relationship) to the server, so that the server records the information. The server may send a platform change instruction including the changed access information of the second cloud platform and the second protocol mapping relationship between the second cloud platform and the gateway device to the gateway device, so that the gateway device and the terminal device managed by the gateway device access the second cloud platform.
And 504, accessing the second cloud platform according to the access information of the second cloud platform, and controlling data communication between the terminal equipment under the gateway equipment and the first cloud platform according to a second protocol mapping relation.
