Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a distributed cluster login method in an embodiment of the present invention, which is applicable to a case where multiple application programs are connected to an internet of things platform and executed by a login server. The method may be performed by a distributed cluster login apparatus, which may be implemented in software and/or hardware, and may be configured in a device, for example, a device having communication and computing capabilities such as a background server. As shown in fig. 1, the method specifically includes:
In the embodiment, the distributed cluster means that different SDKs are set to provide a function of accessing a service data server for an application system, a distributed cluster is formed among the different SDKs, and for a distributed cluster, functions performed by the application system to which the SDKs belong are the same, for example, for an application system such as an unmanned bank, the SDKs below the distributed cluster form a distributed cluster. The target node refers to a service module deployed in the distributed cluster, and in this embodiment, refers to an SDK, which is a software development kit, and is a development tool set used when establishing application software for specific software, a software framework, a hardware platform, an operating system, and the like. The software development tool includes a collection of related documents, paradigms and tools for assisting in developing a certain type of software, for example, for an unmanned bank application system, the SDK in the distributed cluster is used for establishing a connection relationship with a bank server to acquire related business data for an unmanned bank. The login request refers to authentication information sent by a node in the distributed cluster before the node requests to connect with the service data server, and illustratively, the login request includes address information of a target node and the like, so that the application system to which the target node belongs can be conveniently confirmed according to the address information. The service data server is an information bearer based on the internet, a traditional telecommunication network and the like, and enables all common physical objects which can be independently addressed to form an interconnected network. In this embodiment, the service data server refers to an internet of things platform deployed on different servers. For the unmanned bank application system, the internet of things platform connected with the unmanned bank application system provides a server including all business data for a bank.
Specifically, according to the functions of the internet of things platform, a universal API is provided for the application system, and the complete internet of things equipment management capability is covered. All relevant Internet of things platforms provide application SDKs, and are easy to use by developers. Illustratively, the bank internet of things platform provides an API for the unmanned bank SDK to use, and the SDK provides an interface with a standard style for the application system to use so as to realize the calling of the unmanned bank application system to the service data in the bank internet of things platform. When the SDK in the distributed cluster needs to be connected with the Internet of things platform, the SDK is a target node, the target node sends a login request to a login server, and the login server judges whether other nodes in the distributed cluster have information in connection with the service data server, namely whether other nodes request to login and are in a login state before the target node logs in.
Optionally, the login information in the distributed cluster connection is unique. Specifically, the login information refers to the service data servers connected to all nodes in the distributed cluster, that is, the service data servers connected to the nodes in the same distributed cluster are unique. The SDK which belongs to the same application system is connected with one service data server only, so that the utilization rate of the service data server is improved, and the resource waste is reduced.
Optionally, determining whether there is a connected service data server at another node in the distributed cluster includes:
and determining whether other nodes in the distributed cluster have the service data server in connection according to the connection relation information stored in the storage module in the distributed cluster.
The storage module is configured to store connection relationship information and other information in the distributed cluster, where the connection relationship information refers to information, such as an address and an ID, of a unique service data server connected to the distributed cluster, or information, which is obtained by a target node from the service data server and is related to connection and subsequent data acquisition, such as an ID address of the service data server and type information of acquired data. Optionally, the storage module may be stored in the distributed cluster, or may be stored outside the distributed cluster. For example, HazelCast is established in the distributed cluster, distributed cache information in each node in the distributed cluster is realized, cache information can be viewed by all nodes, and information sharing is realized.
Specifically, if there is a connected service data server in another node in the distributed cluster, there is connected service data server information, such as server address information, in the connection relationship information stored in the storage module in the distributed cluster. And the unique service data server information of the distributed cluster connection can be confirmed according to the address information, so that the resource waste caused by repeated connection is avoided.
And 102, if a connected service data server exists, establishing a connection relation between a target node and the service data server so that the target node accesses the target service data server.
Specifically, if the connection relationship between other nodes and the service data server already exists in the distributed cluster where the target node is located, the information of the connected service data server is determined according to the connection relationship, and the connection relationship between the target node and the service data server is established, so that all nodes in the distributed cluster access the same service data server to obtain related data.
Optionally, a distributed cache is built among the SDKs of the same application system by using the HazelCast, the SDKs configure cache node address information, and the HazelCast automatically builds a distributed cluster by configuration, so that connection information sharing between the SDKs is realized, login steps between the SDKs and the service data server are reduced, and login efficiency is improved.
The embodiment of the invention inquires whether the connected service data server exists in the distributed cluster or not when the login is requested in the distributed cluster, so that the whole distributed cluster is connected with the same target service data server, the problem of resource waste of the service data server caused by repeated connection is avoided, the login steps of the nodes in the distributed cluster are improved, and the login efficiency is improved. The development of upper-layer application is simplified, and meanwhile, the high availability of the service data server is guaranteed.
Example two
Fig. 2 is a flowchart of a distributed cluster login method in the second embodiment of the present invention, and the second embodiment of the present invention is further optimized based on the first embodiment of the present invention. As shown in fig. 2, the method includes:
Specifically, the absence of the connected service data server indicates that no node in the distributed cluster establishes a connection relationship with the service data server, and the target node may be a node that logs in for the first time in the distributed cluster to which the target node belongs. The node needs to carry login verification information to perform verification login, and the verification login is used for verifying the identity information of the distributed cluster. Illustratively, if there is no connected service data server, the target node sends verification information to the login server, where the verification information includes account ID information, password information, and the like, and if the verification information is successfully matched, the target node logs in successfully.
And after detecting that the target node is successfully logged in, determining a target service data server from candidate service data servers, wherein the candidate service data servers can establish a connection relationship with the SDK to provide service data call for the application system. The target service data server refers to a server selected from candidate service data servers and meeting the connection requirement of the target node, for example, the number of SDKs connected by the candidate service data server is the minimum. And sending the selected address of the target service data server to the target node, establishing the connection relation between the target node and the address, and realizing the data call of the target node to the target service data server.
Optionally, determining a target service data server from the candidate service data servers includes:
based on load balancing, a target server is determined from at least two candidate servers.
Load balancing refers to sharing and executing on a plurality of operation units, such as a Web server, an FTP server, an enterprise critical application server, and other critical task servers, so as to collectively complete work tasks. In this embodiment, load balancing refers to allocating connections of SDKs in different application systems to different service data servers.
Specifically, when the application system accesses the service data server through the SDK, the SDK selects one of the servers in turn from the addresses of the plurality of service data servers in the distributed cluster configuration in a polling manner, and invokes the status query interface thereof, if the server is available, invokes the corresponding service, that is, determines that the server is the target server; and if the server is unavailable, sequentially selecting the next server for judgment. For example, the determination that the server is available is determined according to the number of SDKs that are available for connection with the server or the remaining memory of the server. Optionally, the SDK determines that the target server may use a randomly selected service data server based on load balancing, and invokes a state query interface of the randomly selected server.
The login authorization information refers to login information related to the SDK in the application system accessing the target service data server, for example, an authorization token confirmed for the distributed cluster, and is used to determine the type of the service data accessible by the distributed cluster, so as to ensure the validity of the service data accessed by the distributed cluster.
Specifically, after the connection relationship between the target node and the target service data server is established, the acquired information related to login is cached in the distributed cluster, so that when a subsequent node queries the service data server in connection before login, the connection relationship can be directly established, and the login information cached in the distributed cluster can also be directly accessed, thereby realizing information sharing, and avoiding resource waste and influence on login efficiency caused by repeated acquisition of reuse information.
According to the embodiment of the invention, the login information is established in the distributed cluster in a distributed manner, so that one node is established after login, all nodes in the distributed cluster can be shared, the cache information can be shared by a plurality of nodes, the access pressure to a service data server is reduced, and the access times to the platform of the Internet of things are reduced. If the login reuse information of the node under the application system is not cached, the internet of things platform needs to be accessed for each login, data is acquired in real time, a certain time is consumed for each request, and therefore efficiency is low.
Optionally, the method further includes:
and if the connection failure between any node in the distributed cluster and the service data server is detected, re-determining a new service data server from the rest candidate servers, and re-establishing the connection relationship between the node connected with the original service data server in the distributed cluster and the new service data server.
Specifically, if it is detected that any node in the distributed cluster fails to connect with the service data server, it indicates that the connection between the target node and the target service data server fails in the first connection, or the first connection between the target node and the target service data server succeeds, but the connection is disconnected in the subsequent access process due to various reasons.
If the connection failure between any node in the distributed cluster and the service data server is detected, the node actively triggers and reselects a new service data server, optionally polls the remaining candidate servers based on a load balancing principle, determines that a certain available server exists in the remaining candidate servers, establishes the connection relationship between the node and the server, sends the address of the re-determined server to the node connected with the original target service data server, establishes the connection relationship between each node and the server, and disconnects the connection with the original target service data server. All nodes in the distributed cluster are ensured to be connected with only one service data server, the utilization rate of the service data server is improved, and the pressure of the Internet of things platform caused by multiple connections is greatly reduced.
Optionally, the distributed cluster function is realized by adopting HazelCast inside the SDK of the application system, the application system does not need to consider the problems of load balancing, distributed deployment and the like, the development of an upper-layer application system is simplified, and high availability is realized better.
The embodiment of the invention determines the connected servers for the nodes in the distributed cluster based on load balancing, thereby improving the connection utilization rate of the servers; the SDK nodes are self-grouped and distributed, load is transferred to a plurality of nodes from a single node, the whole application system is prevented from being crashed due to the failure of the single node, and login efficiency is improved. And the login information is cached in a distributed mode, information sharing among cluster nodes is achieved, and the access pressure to the Internet of things platform is reduced. The embodiment of the invention ensures the realization of the SDK login function under the application system and simultaneously considers the access efficiency.
