[0054] In order to make the purposes, technical solutions and advantages of the present application clearer, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0055] The asynchronous communication method provided in the embodiments of the present application can be applied to an application environment as shown in Figure 1 . In the application environment, the target service node 102 communicates with each service node 104 in the asynchronous communication cluster through a network. The processing performance parameters of each service node 104 are obtained, and a first cluster and a second cluster of the asynchronous communication cluster are constructed according to the processing performance parameters of each service node.

[0056] In one embodiment, as shown in Figure 2 , an asynchronous communication method is provided. The asynchronous communication method is applied to the target service node in Figure 1 , and includes the following steps.

[0057] In S201, the target node in the asynchronous communication cluster constructs a first cluster and a second cluster of the asynchronous communication cluster according to the processing performance parameters of each service node in the asynchronous communication cluster. The first cluster includes a first master node and a first slave node, and the second cluster includes a second master node and a second slave node.

[0058] In the embodiments of the present application, each service node generates a voting request according to its own processing performance parameter, and sends the voting request to the target service node. Optionally, each service node can read the processing performance parameter from a preset database, or each service node can analyze historical processing information to determine its own processing performance parameter. Further, the target service node analyzes each voting request to obtain the processing performance parameter of each service node, and thus constructs a first cluster and a second cluster of the asynchronous communication cluster according to the processing performance parameter of each service node. Optionally, the asynchronous communication cluster includes multiple clusters. In the embodiments of the present application, the asynchronous communication cluster at least includes a first cluster and a second cluster. According to the processing requirement of the asynchronous communication cluster, the number of service nodes in the asynchronous communication cluster, etc., the asynchronous communication cluster can include a third cluster, a fourth cluster, etc.

[0059] Optionally, the target node can evaluate each service node according to the processing performance parameter of each service node to obtain an evaluation value of each service node. The service node with the highest evaluation value can be determined as the first master node, the service node with the evaluation value within a preset range can be determined as the second master node, i.e., the first slave node, and the service node other than the first master node and the second master node can be determined as the second slave node.

[0060] Optionally, when a preset election requirement is met, the voting request sent by each service node in the asynchronous communication cluster is received. The preset election condition can include: (1) the slave service node does not receive the signal of the master service node beyond a preset timeout time; (2) , wherein , respectively represent the message waiting weight of the current service node and the master service node. is a constant, and represents a node switching overhead coefficient.

[0061] S202, the target node receives a service request sent by other service nodes in the asynchronous communication cluster, and sends a reply message corresponding to the service request to the other service nodes according to the service request.

[0062] In the embodiments of the present application, after the target node receives the service request sent by other service nodes in the asynchronous communication cluster, the target node processes the service request, generates a reply message of the service request after the processing of the service request is completed, determines an initiating node initiating the service request and a position of the initiating node in the asynchronous communication cluster according to the service request, and then sends the reply message corresponding to the service request to the initiating node.

[0063] In the above asynchronous communication method, the target node in the asynchronous communication cluster constructs a primary cluster and a secondary cluster in the asynchronous communication cluster according to the processing performance parameters of each service node in the asynchronous communication cluster; the primary cluster includes a primary master node and a primary slave node, and the secondary cluster includes a secondary master node and a secondary slave node; the target node receives a service request sent by other service nodes in the asynchronous communication cluster, and sends a reply message corresponding to the service request to the other service nodes according to the service request. Through the hierarchical service structure of the cluster, the response message is implemented in multiple levels of distribution, and the dependence on the unified intermediate agent is removed, which improves the efficiency of message routing and greatly improves the reliability of the system. After the service request is initiated by the other service nodes, there is no need to obtain the reply request multiple times, and the efficiency of asynchronous communication is improved.

[0064] In one embodiment, an implementation of S202 is provided, as shown in Figure 3 According to the service request, the reply message corresponding to the service request is sent to the other service nodes, which includes:

[0065] S301, determining a message transmission path according to an identifier in the service request.

[0066] In the embodiments of the present application, the message transmission path can be directly determined according to the identifier in the service request; or the path node in the transmission path can be determined according to the identifier in the service request, so as to determine the message transmission path according to the path node.

[0067] S302, transmitting the reply message corresponding to the service request to the other service nodes according to the message transmission path.

[0068] In the embodiments of the present application, the reply message corresponding to the service request is sent to the secondary master node corresponding to the target node according to the message transmission path, the secondary master node sends the reply message to the primary master node, and the primary master node transmits the reply message to other service nodes according to the message transmission path.

[0069] In the above embodiments, the message transmission path is determined according to the service request, and the reply message corresponding to the service request is transmitted to other service nodes according to the message transmission path, thereby improving the accuracy of message transmission.

[0070] In one embodiment, an implementation of S301 is provided, as shown in Figure 4 According to the identification in the service request, the message transmission path is determined, which includes:

[0071] S401, if the other service node is a primary slave node, the first identification of the primary cluster in which the other service node is located and the second identification of the other service node are determined according to the identification in the service request.

[0072] In the embodiments of the present application, if the other service node is a primary slave node, since the secondary master node corresponding to the target node is a primary master node or a primary slave node of the primary cluster, the path from the secondary master node corresponding to the target node to the other service node is determined, the field of target position in the identification in the service request is read, and the first identification of the other service node and the second identification of the other service node are determined.

[0073] S402, if the other service node is a secondary slave node, the third identification of the primary cluster in which the other service node is located, the fourth identification of the secondary cluster in which the other service node is located, and the fifth identification of the other service node are determined according to the identification in the service request.

[0074] In the embodiments of the present application, if the other service node is a secondary slave node, the path from the secondary master node corresponding to the target node to the secondary master node of the other service node and the path from the secondary master node of the other service node to the other service node are determined, and the third identification of the primary cluster in which the other service node is located, the fourth identification of the secondary cluster in which the other service node is located, and the fifth identification of the other service node are determined by reading the field of target position in the identification in the service request.

[0075] Optionally, a schematic diagram of the first cluster and the secondary cluster is as shown in Figure 4AAs shown, the primary master service node is responsible for consuming the response message queue and routing the message to the primary slave service node; the secondary master service node is the same as the primary slave service node, responsible for receiving and forwarding the message from the primary master service node, and the primary slave service node and the secondary slave service node are execution nodes, which start asynchronous processing after receiving the request and synchronously return the request success message. After the asynchronous task processing is completed, the execution result is combined with the request unique identifier and pushed to the public response message queue. After the primary master service node consumes the message, it first judges whether it is the current secondary cluster message, if so, it is forwarded within the secondary cluster, otherwise it is forwarded to the corresponding secondary cluster according to the request identifier.

[0076] In the embodiment of the present application, the asynchronous communication process of the asynchronous communication cluster can include:

[0077] (1) When the asynchronous communication cluster is started, the three service nodes of the same name service are regarded as a secondary cluster, and first, an internal election is initiated to confirm the master service node, and the master service node is initially defaulted as the slave service node of the primary cluster, and the primary cluster initiates an election to confirm the master service node of the primary cluster. In particular, in the first election period, if there is only one service node started in the cluster, the service node automatically becomes the master service node until it receives a voting request of a service node with a higher election value;

[0078] (2) After the initialization networking is completed, the master service node starts to consume and forward the response message;

[0079] (3) After the networking is completed, the service node 1 of the micro service A becomes a slave service node, and initiates an HTTP request in the business operation, and the request unique identifier of this request is generated based on the service identifier A and the service node identifier 1, and is sent to the receiver in the form of a request header.

[0080] (4) After receiving the request, the receiver B performs preprocessing operation, and starts asynchronous task execution based on the request identifier, and then returns the request success to inform the requester to wait asynchronously. After receiving the response, the service node 1 registers the request to the listening queue, and waits for the master service node to push the message result.

[0081] (5) After the asynchronous task execution of the micro service B is completed, the execution result is combined with the request unique identifier, sent to the asynchronous task response message queue, and the request processing is ended;

[0082] (6) After the primary cluster master service node consumes the response message, the message is pushed to the primary cluster slave service node A according to the service identifier A, and the primary cluster slave service node A is also the master service node of the secondary cluster, and at this time, the message is pushed to the service node 1 according to the node identifier 1;

[0083] (7) After the service node 1 receives the response message, the request waiting state is ended, and the request identifier is removed from the listening queue, completing the entire life cycle of the asynchronous request.

[0084] Optionally, within the secondary cluster, the abnormal message can be processed by identifying the slave service node state. For example, if the micro service B2 is unexpectedly terminated during task execution as a slave service node, and the micro service B1 is the master service node that discovers the abnormality through heartbeat detection, the master service node can push an abnormal response to the exception interrupt request identifier held by the micro service B2, reducing the invalid waiting of the requestor. For a large-scale system, by adjusting the cluster level, the service cluster is divided into two parts according to specific rules, and the election process is repeated to control the number of messages forwarded by a single master service node. For scenarios where the service scale is moderate and the number of messages is large, exceeding the load range of a single primary cluster master service node, a multi-primary cluster master service node mode is adopted, and the response queue is consumed simultaneously, and the messages are exchanged between each other.

[0085] In the above application embodiments, the path from the target node to the initiating node is determined according to the unique identifier in the service request, so that the reply message of the service request is returned to the initiating node.

[0086] In one embodiment, an implementation of S201 is provided, as shown in Figure 5 According to the processing performance parameters of the service nodes in the asynchronous communication cluster, a primary cluster and a secondary cluster in the asynchronous communication cluster are constructed.

[0087] S501, according to the processing performance parameters of the service nodes in the asynchronous communication cluster, a plurality of secondary master service nodes and a plurality of secondary slave service nodes in the asynchronous communication cluster are determined, and a secondary cluster in the asynchronous communication cluster is constructed according to the secondary master service nodes and the secondary slave service nodes.

[0088] In the embodiments of the present application, the asynchronous communication cluster includes a plurality of service nodes, and the plurality of service nodes in the asynchronous communication cluster are divided into a plurality of service node groups according to preset grouping information. Further, the target service node obtains the processing performance parameters of the service nodes in the asynchronous communication cluster. For each service node group, the service nodes in the service node group are sorted according to the processing performance parameters of the service nodes in the service node group, the service node with the best performance is determined as the secondary master service node in the service node group, and the other service nodes in the service node group except the secondary master service node are determined as the secondary slave service nodes, so as to construct the service node group into a secondary cluster. Optionally, the processing performance parameter can be the hardware parameter of the service node, so as to evaluate the hardware parameter to obtain the evaluation value of each service node, and further, the service nodes are sorted according to the evaluation value of each service node.

[0089] Optionally, according to the ranking result of the performance sorting of the service nodes in the service node group according to the processing performance parameters of the service nodes, voting is performed on the service nodes, for example, a vote of approval is cast for the service node ranked first, and a vote of disapproval is cast for the service nodes other than the service node ranked first.

[0090] S502, according to the processing performance parameters of the secondary master service nodes, determining the primary master service node and the plurality of primary slave service nodes in the asynchronous communication cluster, and constructing a primary cluster according to the primary master service node and the primary slave service nodes.

[0091] In the embodiments of the present application, the plurality of secondary master service nodes are grouped into a primary cluster, and the primary master service node and the primary slave service nodes are determined from the plurality of secondary master service nodes, the secondary master service nodes in the primary cluster are sorted according to the processing performance parameters of the secondary master service nodes, the secondary master service node with the best performance is determined as the primary master service node in the primary cluster, and the other service nodes in the primary cluster other than the primary master service node are determined as the primary slave service nodes. It should be noted that the method of constructing the primary cluster is the same as the method of constructing the secondary cluster.

[0092] In the above embodiments, the asynchronous communication cluster is divided into a primary cluster and a secondary cluster, multi-level distribution is implemented on the response message, the dependence on the unified intermediate agent is removed, the complexity of asynchronous processing is reduced, the efficiency of message routing is improved, the reliability of the system is greatly improved, and the accuracy of the primary cluster and the secondary cluster is improved according to the processing performance parameters of the service nodes to determine the primary master service node, the primary slave service node, the secondary master service node and the secondary slave service node.

[0097] S602, determine the forwarding weight of each service node according to the waiting weight of each service node.

[0098] In the embodiment of the application, for each service node, the forwarding weight of each service node is determined according to the waiting weight of all service nodes in each service node group except the service node.

[0099] Optionally, the corresponding relationship between the waiting weight and the forwarding weight can be established in advance, so that the forwarding weight of each service node is determined according to the waiting weight of each service node; or the forwarding weight of each service node can be determined according to the waiting weight of each service node and a preset second relationship.

[0100] S603, determine the service node with the highest forwarding weight in each group of service nodes in the asynchronous communication cluster as the secondary master service node, and determine the service nodes other than the secondary master service node as the secondary slave service nodes.

[0101] In the embodiment of the application, the service node with the highest forwarding weight in each group of service nodes in the asynchronous communication cluster is determined as the secondary master service node, and the service nodes other than the secondary master service node are determined as the secondary slave service nodes. Optionally, the service node with the lowest forwarding weight can be removed from the secondary cluster.

[0102] In the above application embodiment, the waiting weight of the service node is determined according to the priority coefficient and the request response time, which improves the credibility of the waiting weight. Further, the forwarding weight is determined according to the waiting weight, which improves the credibility of the forwarding weight, thereby improving the accuracy of the secondary master service node and the secondary slave service node in the secondary cluster.
