Derek interprets Bytom source-API Server Interface Service

first reads the request content, parses the request, matches the corresponding route entry, and then calls the handler callback function of the route entry to process. Finally handler the request after processing the requests to BYTOMCLI. Api-server Source Code Analysis During the BYTOMD boot process, BYTOMD uses Golang standard library HTTP.

Golang: Building an API server with Httprouter

This is a creation in Article, where the information may have evolved or changed. I began to become a Gopher 10 months ago, without turning back. Like many other gopher, I quickly discovered that simple language features are very useful for quickly building fast, scalable software. When I first started learning Go, I was playing with a different multiplexer (multiplexer) that could be used as an API server. If you have Rails backgrounds like me, you may also encounter difficulties in building a
