In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flow diagram illustrating a long-connection communication method according to an example embodiment, which may involve a target client and a long-connection server cluster, as shown in fig. 1, wherein the long-connection server cluster may contain a plurality of long-connection servers. The target client can be any client, and the long connection target server can be any long connection server in the long connection server cluster. In practical application, the target client may be connected to any long connection server in the long connection server cluster through a variety of scheduling algorithms or third party load balancing. The target client maintains a long connection link with a long connection target server in the long connection server cluster.
The long-connection communication method shown in fig. 1 may specifically include the following steps.
In step S11, a long-connection storage server is acquired from the long-connection server cluster.
In the embodiment of the present disclosure, the long connection server in the long connection server cluster may also serve as a storage node, that is, the long connection storage server may be selected from the long connection server cluster, and the long connection storage server is used as the storage node. That is, the storage nodes are located inside a long-connection server cluster. In practical application, the long-connection storage server can be acquired from the long-connection server cluster based on a consistent hashing algorithm.
In step S12, the key-value pair between the target client and the long-connection target server is stored in the long-connection storage server.
In an embodiment of the present disclosure, the key-value pair between the target client and the long connection target server may include identification information of the target client and address information of the long connection target server. Moreover, the identification information of the target client and the address information of the long connection target server are combined into a key value pair, that is, the identification information of the target client and the address information of the long connection target server appear in pairs. The long-connection storage server serves as a storage node, and key value pairs can be stored in the storage node.
In step S13, a target service message is received.
In the embodiment of the present disclosure, a target service message of a service system may be received, where the target service message is used to be sent from the service system to a target client. In practical applications, the target service message may contain identification information of the target client.
In step S14, the target key-value pair corresponding to the target service message is acquired from the long-connection storage server.
In the embodiment of the present disclosure, if the target service message is to be forwarded to the target client, the target service message needs to be transmitted through the long connection link between the long connection target server and the target client. Therefore, the target key value pair can be acquired from the storage node, namely the address information of the long connection target server establishing the long connection link with the target client is acquired from the storage node
In step S15, the target service message is forwarded to the target client according to the target key-value pair and the long connection link.
In the embodiment of the present disclosure, after the target key value pair is acquired, that is, after the address information of the long connection target server maintaining the long connection link with the target client is acquired, the target service message may be transmitted to the target client through the long connection link between the long connection target server and the target client. Thus, the process that the target service message of the service system is forwarded to the target client through the long connection server cluster is completed.
The embodiment of the disclosure provides a long connection communication scheme, which relates to a target client and a long connection server cluster. The long connection link is maintained between the target client and the long connection target server in the long connection server cluster, and the embodiment of the disclosure can acquire the long connection storage server from the long connection server cluster, and further store the key value pair between the target client and the long connection target server into the long connection storage server. After receiving the target service message, the target key value pair corresponding to the target service message may be acquired from the long connection storage server, and the target service message may be forwarded to the target client. Embodiments of the present disclosure store key-value pairs between a target client maintaining a long connection link and a long connection target server within a long connection server cluster. Namely, the long connection storage server in the long connection server cluster is used as a storage node, and the storage node is used for storing the key value pair between the target client and the long connection target server, so that the key value pair is prevented from being stored in a third-party storage center, the risk that a long connection link between the target client and the long connection target server is leaked is reduced, and the consumption of operation cost is reduced.
In an exemplary embodiment of the present disclosure, referring to fig. 2, fig. 2 shows a flowchart of directly or indirectly forwarding a target service message to a target client by an arbitrary long connection server. One implementation manner of forwarding the target service message to the target client according to the target key value pair and the long connection link is that any long connection server in the long connection server cluster may directly or indirectly forward the target service message to the target client. Therefore, the current long connection server can be acquired from the long connection server cluster according to a preset scheduling algorithm, and the target service message is sent to the current long connection server. The current long connection server may be any long connection server. In practical applications, the preset scheduling algorithm may include, but is not limited to: polling algorithm, right-based polling algorithm, hash algorithm, and the like. And then judging whether a target client corresponding to the target service message keeps a long connection link with the current long connection server, if so, directly forwarding the target service message to the target client according to the long connection link. If a long connection link is not maintained between the target client corresponding to the target service message and the current long connection server, the long connection storage server storing the key value pair of the target client and the long connection target server can be obtained, and then the target key value pair is obtained from the long connection storage server, and specifically, the address information of the long connection target server in the target key value pair can be obtained.
In an exemplary embodiment of the present disclosure, after the target key-value pair is obtained from the long-connection storage server, it may be further determined whether the current long-connection server is the long-connection target server according to the target key-value pair. Specifically, it may be determined whether the address information in the target key value pair is the same as the address information of the current long connection server. If the address information in the target key value pair is the same as the address information of the current long connection server, determining that the current long connection server is the long connection target server; if the address information in the target key value pair is not the same as the address information of the current long connection server, it may be determined that the current long connection server is not the long connection target server.
If the current long connection server is a long connection target server, but the target client corresponding to the target service message is determined before, and a long connection link is not kept between the target client and the current long connection server, the target client can be determined to be in an offline state, and then prompt information indicating that the target client is offline is returned to the current long connection server, and then the prompt information is returned to the service system through the current long connection server.
If the current long connection target server is not the long connection target server, the target service message can be forwarded to the long connection target server according to the address information of the long connection target server in the target key value pair, and the target service message is forwarded to the target client from the long connection target server through the long connection link.
In an exemplary embodiment of the present disclosure, referring to fig. 3, fig. 3 shows a schematic diagram of an establishment flow of a long connection server cluster. The long connection server cluster can register all the long connection servers to a third-party service registration center, and monitor whether the long connection servers change or not through the third-party service registration center. If the number of the long connection servers in the long connection server cluster is changed, the key value pairs stored in the long connection servers can be hashed again; if the number of long connection servers in the long connection server cluster is not changed, no other operation may be performed. It should be noted that, in addition to registering the long-connection server in the long-connection server cluster with the service registry of the third party, the long-connection server in the long-connection server cluster may also be registered with a service registry (e.g., a long-connection registry server) in the long-connection server cluster. The long-connection registration server may be selected from a plurality of long-connection servers of a long-connection server cluster. Embodiments of the present disclosure do not specifically limit the location of the service registry of the long connection server within the long connection server cluster or at the third party server.
In an exemplary embodiment of the present disclosure, referring to fig. 4, fig. 4 shows a flowchart illustrating a target client establishing a long connection link with a long connection target server. The target client can be connected to the long-connection target server through a scheduling algorithm or third-party load balancing. The long connection target server may maintain a long connection link with the target client. And then, acquiring a storage node from the long connection server cluster through a consistent hash algorithm, and storing a key value pair between the target client and the long connection target server into the storage node.
Based on the above description of an embodiment of a long-connection communication method, a long-connection communication system is described below. Referring to fig. 5, fig. 5 shows a schematic diagram of a long connection communication system. The long connection communication system may include a long connection server Cluster (Cluster), which may include five long connection servers, which are nodes S1, S2, S3, S4, and S5, respectively, and the five long connection servers may communicate with each other. Each long connection server provides long connection link management functions and Key-Value pair (K-V) storage services. Each long connection server is registered with a service registry. Any client (Agents) may connect to any of the five long connection servers. The long connection server connected with the client can store the key value pairs on the storage nodes, and particularly, the storage nodes can be obtained through calculation of a consistent hash algorithm.

The system may involve a target client with a long-connection server cluster, where the long-connection server cluster may contain a plurality of long-connection servers. The target client can be any client, and the long connection target server can be any long connection server in the long connection server cluster.
