GoLang之Engine结构体方法

本文基于github.com/gin-gonic/gin v1.7.7依赖进行讲解

1.Engine结构体

type Engine struct {
	RouterGroup
	RedirectTrailingSlash bool
	RedirectFixedPath bool
	HandleMethodNotAllowed bool
	ForwardedByClientIP bool
	AppEngine bool
	UseRawPath bool
	UnescapePathValues bool
	RemoveExtraSlash bool
	RemoteIPHeaders []string
	TrustedPlatform string
	MaxMultipartMemory int64
	delims           render.Delims
	secureJSONPrefix string
	HTMLRender       render.HTMLRender
	FuncMap          template.FuncMap
	allNoRoute       HandlersChain
	allNoMethod      HandlersChain
	noRoute          HandlersChain
	noMethod         HandlersChain
	pool             sync.Pool
	trees            methodTrees
	maxParams        uint16
	maxSections      uint16
	trustedProxies   []string
	trustedCIDRs     []*net.IPNet
}

2.Run方法

// Run attaches the router to a http.Server and starts listening and serving HTTP requests.
// It is a shortcut for http.ListenAndServe(addr, router)
// Note: this method will block the calling goroutine indefinitely unless an error happens.
func (engine *Engine) Run(addr ...string) (err error) {
	defer func() { debugPrintError(err) }()

	if engine.isUnsafeTrustedProxies() {
		debugPrint("[WARNING] You trusted all proxies, this is NOT safe. We recommend you to set a value.\n" +
			"Please check https://pkg.go.dev/github.com/gin-gonic/gin#readme-don-t-trust-all-proxies for details.")
	}

	address := resolveAddress(addr)
	debugPrint("Listening and serving HTTP on %s\n", address)
	err = http.ListenAndServe(address, engine)
	return
}
