Description
Technical Field
The invention relates to a plurality of protocol processing technologies, in particular to an anomaly control method and device based on a STOMP protocol.
Background
Along with the development of technology, the requirement on information timeliness is higher and higher, so that the STOMP combined with WebSocket can keep long connection and is applied to a simple full duplex protocol, the STOMP keeps the WebSocket link through heartbeat messages, if a server judges that abnormality occurs, a message with an ERROR head is actively initiated, the TCP link established by the WebSocket is broken inside the protocol, and the STOMP is also frequently used in a distributed micro-service architecture.
As shown in fig. 1, a client selects a business service to establish WebSocket link through gateway forwarding protocol in a load balancing manner; but there are also some uncertainties among them:
1. under some abnormal conditions, the business service firstly initiates a message with an ERROR header, the message is forwarded to the client, the connection between the client and the gateway is broken, but the connection between the gateway and the business service continues to exist, and the repeated steps can lead the TCP link to expand infinitely so that the server crashes;
2. in some abnormal cases, all links are broken by the server uniformly, and important links cannot be distinguished, so that important business is interrupted.
Disclosure of Invention
In order to overcome the defects of the related prior art, the invention provides an abnormal control method and device based on a STOMP protocol, which ensure that a service end does not automatically disconnect a link and a client can identify and confirm whether the link is disconnected or not by monitoring the number of TCP connections between services and intercepting a message with an ERROR header and expanding the message into a special command, thereby ensuring the maximum possible lossless execution of important tasks.
In order to achieve the object of the invention, the following scheme is adopted:
An anomaly control method based on STOMP protocol is applied to a framework with WebSocket links established among a client, gateway service and a plurality of business services, and comprises the following steps:
the gateway service address is configured on the business service, a TCP link monitoring thread based on the address is created, and a command is used: netstat-apn |grep|grep gateway IP to monitor TCP link number;
Creating a STOMP exception interception program in the business service to perform STOMP exception interception;
creating a command extension program in the business service to create a TCP link overrun message when the number of the TCP links is monitored to be larger than a preset threshold value, and creating an abnormal extension message when an abnormality is intercepted;
sending TCP link overrun message and exception extension message to the established link exception client;
The client receives the TCP link overrun message, sends an abnormal message to the gateway service which has established connection, breaks off the WebSocket link between the client and the gateway service and the WebSocket link between the gateway service and the business service, and then automatically reconnects;
The client receives the abnormal extension message and judges whether the current WebSocket link belongs to a link in a preset important link table or not: if yes, sending an abnormal message to the gateway service with established connection, disconnecting the WebSocket link of the client and the gateway service, and the WebSocket link of the gateway service and the business service, and then automatically reconnecting; if not, the process ends.
The invention has the beneficial effects that:
the method and the device can keep the smoothness of important services to the greatest extent, avoid the problem of too high TCP link quantity caused by WebSocket, and ensure the normal operation of the system.
