The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, the present invention provides an internet of things service cloud architecture and a radio frequency test system using the cloud architecture, including:
the API gateway is used for receiving an access request of a user, authenticating the identity of the user through the authentication unit, and forwarding the access request to a corresponding service according to the mapping relation between the access request and the service;
the system management unit is used for carrying out authority distribution by an administrator according to the user role information and carrying out unified distribution on the access requests through the configuration center;
the configuration center is used for registering the service to the service registration center, creating a configuration file with configuration information, and correspondingly matching the stored address, the user name and the password according to the configuration information;
the service registration center is used for registering the service to an Eureka Server of the service registration center, the registration information is stored in a database after the registration is successful, the database comprises a Redis database and a Mysql database, the Mysql database is supported by a main database and a standby database, the writing in of the main database is realized in a dynamic data source mode, the query from the database is realized, the read-write separation is realized, the configuration information is obtained by accessing the Eureka Server, and the remote service is called according to the configuration information to realize the access to the service. The API gateway is the only node entering the system and is responsible for service request routing, combining and protocol conversion, external user access requests are scheduled and filtered through the API gateway, and users who are maliciously accessed by the dequeue system are filtered and then are issued to corresponding specific services, because the safety of the system is very important for the accessed third-party application system. Adding service port in the configuration file, after the task is started, registering the task to the service registration center, configuring request routing rule according to the service name, and when the actual request is consistent with the mapping relation of the rule, forwarding the request to the corresponding service for processing. The configuration information management is unified through the Config, the configuration files are uniformly stored in the warehouse, and then the system service acquires the configuration information through the Config Server. The configuration Server is deployed with a plurality of nodes and has the same service name, and then the nodes are registered in the service registration center, so that the system service can search the configuration Server according to the service name to acquire configuration information, even if some node of the configuration Server is abnormal, the configuration center can work normally, and the high availability of the configuration center is realized.
As shown in fig. 2, in this embodiment, the authentication unit further includes a client, an authentication server and a resource server, when the user opens the client of the third-party application software, the user receives an authorization request and sends back authorization information to the client, the client requests the authentication server for a token for accessing data according to the authorization information, the authentication server verifies the authorization information, sends the token to the client after verification, the client carries the token to send the access request to the resource server, and the resource server verifies the token to determine whether the token is correct, and if so, feeds back related data to the client.
In this embodiment, further, the authorization request is configured with a storage path, client information, and an operation type.
In this embodiment, further, the configuration information includes a service name and a service address, and after the configuration information is registered in the service registry, the service registry performs remote invocation of the service according to the service name through the feign component, and the service registry converts the service name and the service address. When a service in the system fails, other services depending on the service all have faults, the faults are enlarged, an avalanche phenomenon occurs, and the faults of the whole system are caused; if the service calling fails or the number of times of failure reaches the upper limit, the hystrix breaker is started, the remote service is fused, the hystrix breaker enters a semi-closed state after a period of time, if the service calling succeeds, the hystrix is completely closed, otherwise, the hystrix is started and the remote service is subjected to a fault-tolerant process, and therefore the avalanche effect between service instances is avoided.
In this embodiment, further, a white list containing server IP information is stored in the database, the IP information of the server accessed maliciously is filtered, when the access request passes through the API gateway, it is determined whether the IP information of the server is in the white list, if so, the request is passed, otherwise, the access request is intercepted.
In this embodiment, further, invoking the remote service specifically finds an address of service deployment according to the service name by the feign, and when the address of service deployment changes, automatically registers the updated address of service deployment to the service registration center. The service registration center comprises an Eureka Client and an Eureka Server, the Eureka Client is integrated in the service and registered in the Eureka Server, the configuration information including a service name and a service address of the service in the system can be acquired by visiting the Eureka Server, when intermodulation between the service and the service occurs, the Eureka Server is visited first, the address of the service deployment is acquired according to the service name, then remote calling of the service is carried out, the Eureka Client is used for caching the registration information of the service, and when the Eureka Server is unavailable, the remote service can be called through the cached registration information. When the Eureka servers are deployed, registration information of services is copied between the Eureka servers to realize data synchronization.
In this embodiment, further, the service name is called between services, and the configuration information is obtained by the service name, so as to find the service corresponding to the service name.

Because many functions of the cloud architecture system need to be called among services, each service needs to perform identity authentication and authority authorization on an access request, if one service has a problem, other service data are intercepted, even the system is rushed, and therefore the account number and the password of a user need to be verified. However, if the account password of the same user needs to be checked every time, time waste is caused to the software system, and the system is delayed. Therefore, the single sign-on can be realized only by once sign-on of the user in the intranet through the authentication protocol, and other subsystems can authenticate the identity of the user, so that the trouble of repeated sign-on is avoided.
In this embodiment, the authentication protocol is set as OAuth or CAS, and when the third-party application accesses the system, the OAuth or CAS is adopted to provide protected data for the third-party application by authorizing access, so as to avoid leakage of an account password of the user, thereby improving security and reliability of data transmission.
