Android Network Architecture-OkHttp + Volley + Gson, okhttpgson Previously, HttpClient was encapsulated by itself. However, Volley is used for mainstream network requests, and OkHttp is also very popular. These frameworks are not introduced. This article uses Volley to process Http requests in combination with OkHttp, and uses Gson custom requests to implement An

Objective:We have to use containers, naturally we can not avoid the container design generation process, and after the build is related to load operation and management, so today we are from the design of delivery and architecture of the two aspects of the container.Note: This issue is shared by the creator of the original, Yun Shu network finishing release.In the previous article, "Container origin" says w

service and the service relationship is said to be the interface relationship.5. Open Systems Interconnection: Interactions between systems involve only the external behavior of the system and are independent of the structure and function within the system. Thus, any standard on interconnection systems is only a provision for the external characteristics of the system.6. Each open system consists of a number of contiguous subsystems, a hierarchy of subsystems on the same line as all interconnec

The main function of the Unreal Engine's network architecture is to keep the information of the server and client synchronized by replication actor,variable and function. Each class of Unreal has a copy statement replication{}. The variables and functions can be duplicated in this block.This is a copy of the statement in the PlayerreplicationReplication{ //服务器应该发送到客户断的数据。 if ( bNetDirty ( Role == Rol

Web server, FTP server and other network applications have "one answer" communication logic, so the above using the Libev library "one answer" model for the construction of similar server programs have a reference value; Also, for applications that require remote monitoring or remote control, The above model also provides a feasible implementation scheme.SummarizeThis article focuses on how to build a server program that provides a "one-answer", whic
