Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Technical term interpretation:
the rest, i.e. Representational State Transfer, is a software architecture style, design style, and not a standard. This system is usually said to be Restful if several conditions for rest are met.
rpc, remote procedure calls, a standard that masks underlying communication details, can be called directly. Simply stated, rpc is a function or method (which may be collectively referred to as a service) called from one machine (client) through parameter passing on another machine (server) and gets the result back. rpc are used in the same manner as local functions (or methods) are called to call remote functions (or methods).
mq, a message queue, is a cross-process communication mechanism for upstream and downstream delivery of messages. In the internet architecture, mq is a message communication service of upstream and downstream 'logical decoupling + physical decoupling'. With mq, the messaging upstream only needs to rely on mq, neither logically nor physically relying on other services. In addition, mq is only used to transfer the message that the execution of the upstream task is completed, and is not used to transfer the real input and output data.
The socket is composed of an ip address of a network layer and a port number of a transport layer, and can uniquely mark a process in the network. (the ip address of the network layer can uniquely identify the host, and the port number of the transport layer can uniquely identify a process of the host). socket is an abstraction layer between the application layer and the transport layer that abstracts the complex operations of the TCP/IP layer into several simple interface provisioning layer calls to implemented processes to communicate in the network. The socket is realized in an 'open-read/write-close' mode, a server and a client respectively maintain a 'file', after connection is established and opened, the content can be written into the file of the server for the opposite side to read or read, and the file is closed when communication is finished.
