Controller实现

[johncming]

Instance

控制器里面包含了实例 实例相当于server

Context

type httpContext struct {
    instance *caddy.Instance

    // keysToSiteConfigs maps an address at the top of a
    // server block (a "key") to its SiteConfig. Not all
    // SiteConfigs will be represented here, only ones
    // that appeared in the Caddyfile.
    keysToSiteConfigs map[string]*SiteConfig

    // siteConfigs is the master list of all site configs.
    siteConfigs []*SiteConfig
}

上下文与实例有关系 实例与站点配置有关系 服务类型是逻辑，控制器等相关是逻辑运行所需要的配置 控制器解析配置文件

注册serverTypes

httpserver plugin中默认注册一个http的服务类型

http服务类型

    caddy.RegisterServerType(serverType, caddy.ServerType{
        Directives: func() []string { return directives },
        DefaultInput: func() caddy.Input {
            if Port == DefaultPort && Host != "" {
                // by leaving the port blank in this case we give auto HTTPS
                // a chance to set the port to 443 for us
                return caddy.CaddyfileInput{
                    Contents:       []byte(fmt.Sprintf("%s\nroot %s", Host, Root)),
                    ServerTypeName: serverType,
                }
            }
            return caddy.CaddyfileInput{
                Contents:       []byte(fmt.Sprintf("%s:%s\nroot %s", Host, Port, Root)),
                ServerTypeName: serverType,
            }
        },
        NewContext: newContext,
    })
