To further illustrate the object of the present invention, the above embodiments are further illustrated.
Fig. 2 is a flowchart of a second method for operating resources of the internet of things according to the present invention, and as shown in fig. 2, the method for operating resources of the internet of things provided by the present invention is applied to an operating system of resources of the internet of things, where the operating system of resources of the internet of things includes a server and a client; the method may comprise the steps of:
step 201, the server establishes communication connection with the client.
The server and the client can establish communication connection through a private network or a network provided by an operator, so that the communication function between the server and the client is realized.
Step 202, the server generates a first APIKey for the registered user existing in the client and the same as the registered user existing in the server, and sends the first APIKey to the client.
The first APIKey is used for determining the operation authority of a registered user in the client to the Internet of things resources in the Internet of things resource database of the server; namely, the first APIKey is used for indicating whether the registered user has the corresponding operation authority for at least one internet of things resource in the internet of things resource database.
The Internet of things resource database is established according to the resource types of the Internet of things resource model and contains various Internet of things resources; the resource types of the resource model of the internet of things comprise users, equipment, data streams, data points, triggers, commands and the like; the user is a registered user existing in the server, each registered user can establish a plurality of items, each item can add a plurality of devices, the devices have device IDs, one device can only belong to one item, one device can add at least one data stream, and/or at least one data point, and/or at least one trigger, and/or at least one command and the like; for example, the internet of things resource may include a registered user corresponding to a plurality of different devices, each device corresponding to a plurality of different data streams and a plurality of different commands.
The resource database of the internet of things is a distributed database, and the distributed database comprises a Key Value Key-Value database and a binary form persistent database; the Key-Value database comprises a master database and a slave database, wherein the master database has a read-write function, and the slave database has a read function; the binary form persistent database has a multi-copy storage function.
The Key-Value database is configured according to a master-slave relation, the master database updates and synchronizes the resources of the internet of things to the slave database through a master-slave replication mechanism, the master database can be written and read, and the slave database can be read, so that the concurrency of system services can be increased; the binary form persistent database has a multi-copy storage function, namely, the resources of the internet of things can be stored in multiple copies, and data disaster tolerance is realized.
Step 203, the client presents the HTTP operation request and the configuration content of the HTTP operation request on the screen.
The client side utilizes a debugging tool to realize the visual configuration of the HTTP operation request and the configuration content of the HTTP operation request for the use and operation of a registered user; the configuration content of the HTTP operation request includes an Application Programming interface uniform Resource Locator (api) address and an APIKey, and may further include any one or any combination of a request method, a request parameter, a request content, and the like, and the HTTP operation request includes at least any one or any combination of a POST operation request, a PUT operation request, a GET operation request, and a DELETE operation request.
By supporting the visual operation execution mode of the client, the quick operation of the resources of the Internet of things is realized, and the operation and management of the registered user are more convenient and efficient.
And step 204, the client sends an HTTP operation request to the server.
When a registered user operates at least one internet of things resource which is desired to be operated in a server through a client, the client sends an HTTP operation request to the server through a universal standard interface, wherein the HTTP operation request is used for operating at least one internet of things resource in an internet of things resource database of the server, namely, the registered user can simultaneously operate on one or more internet of things resources; wherein the HTTP operation request includes: at least any one item of a POST operation request, a PUT operation request, a GET operation request, a DELETE operation request is added, or any combination of the items.
In addition, the HTTP operation request carries a first APIKey or a second APIKey, where the first APIKey is allocated to the client by the server in step 102, and the second APIKey is a part of the first APIKey, that is, is included in the first APIKey; it can be understood that the first APIKey has the maximum and most access rights to the internet-of-things resources in the internet-of-things resource database of the server, and the second APIKey has only partial access rights in the first APIKey.
The server judges whether the client has the authority of corresponding operation according to the received current APIKey sent by the client, and completes the authority authentication once; therefore, compared with the prior art, the client and the server do not need to check for many times according to the preset algorithm to authenticate the authority when the request is operated every time, the authority authentication can be completed only once, and the calculation and check are not needed to be performed by the preset algorithm, so that the system resources can be effectively saved, and the expenditure is reduced.
And step 205, the server performs partitioning according to the subject of the HTTP operation request to obtain a plurality of message queues.
And the server partitions according to the theme of the HTTP operation request, divides the HTTP operation request into a plurality of message queues and obtains a plurality of message queues.
Preferably, before the step, that is, after the server receives the HTTP operation request sent by the client, the server performs scheduling management on the HTTP operation request according to a resource scheduling algorithm to obtain a scheduled HTTP operation request; then, the server partitions according to the theme of the scheduled HTTP operation request to obtain a plurality of message queues; the resource scheduling algorithm is added to schedule and manage the HTTP operation request, so that the quality of system service can be further ensured.
And step 206, the server caches the received HTTP operation request in a message queue corresponding to the subject of the HTTP operation request.
And the server caches the received HTTP operation request in a message queue corresponding to the subject of the HTTP operation request.
Preferably, the server may update the corresponding message queue obtained in step 206 according to a cache deletion mechanism, so as to obtain an updated corresponding message queue; the cache deletion mechanism comprises a first mode or a second mode; the first mode is a mode of replacing the HTTP operation request with the longest cache time in the corresponding message queue with a new HTTP operation request when the new HTTP operation request exceeds the queue range after being stored in the corresponding message queue; the second mode is a mode of regularly deleting all HTTP operation requests in the corresponding message queue according to the least recently used LRU algorithm; then, the server caches the received HTTP operation request in an updated corresponding message queue corresponding to the subject of the HTTP operation request; by updating and deleting the message queue corresponding to the subject of the HTTP operation request, the valid HTTP operation request is stored, and the invalid HTTP operation request is removed, so that the quality of system service can be further ensured.
And step 207, the server side reads the HTTP operation request in the corresponding message queue and operates the resources of the Internet of things.
The specific implementation process of the server side reading the HTTP operation request in the corresponding message queue and operating the resources of the Internet of things is an asynchronous reading process, the asynchronous reading process is that a processing process carries out asynchronous interaction with the distributed database server when the operation request is executed, and according to the difference of the operation requests, the specific implementation process is as follows:
the execution process of the POST operation request comprises the following steps: the POST operation request is stored in a message queue after being adapted by a protocol, the POST operation request is read and executed by a processing process, and the resources of the Internet of things are stored in a Key-Value database and also stored in a binary form persistent database.
The execution process of the PUT operation request comprises the following steps: and the PUT operation request is stored in a message queue after protocol adaptation, the PUT operation request is read and executed by a processing process, and the resources of the Internet of things are stored in a Key-Value database and also stored in a binary form persistent database.
Executing the GET operation request: the GET operation request is stored in a message queue after protocol adaptation, a processing process reads and executes the GET operation request, the time of the requested Internet of things resource is judged, according to time limit, if the GET operation request is the latest data, the GET operation request is directly read from a Key-Value database, and if the GET operation request exceeds the time limit, the GET operation request is read from a binary form persistent database.
DELETE operation request execution Process: the DELETE operation request is provided with an identification bit, the server side records the identification bit, and a periodic check mechanism is adopted to DELETE the Internet of things resources corresponding to the identification bit in the distributed database server.
By adding the asynchronous reading service, the performance of accessing the resources of the Internet of things can be guaranteed, and the safety of the resources of the Internet of things can also be guaranteed.
And step 208, the server side obtains the operation result and sends the operation result to the client side.
The server side obtains a final operation result and sends the operation result to the client side;
