g是一个强耦合的模块，目的是为开发者在对频繁使用的类型/对象调用时提供便利。

使用方式：

数据类型

常用数据类型别名。

  1. type (
  2.     Var = gvar.Var        // Var is a universal variable interface, like generics.
  3.     Ctx = context.Context // Ctx is alias of frequently-used context.Context.
  4. )
  6. type (
  7.     Map        = map[string]interface{}      // Map is alias of frequently-used map type map[string]interface{}.
  8.     MapAnyAny  = map[interface{}]interface{} // MapAnyAny is alias of frequently-used map type map[interface{}]interface{}.
  9.     MapAnyStr  = map[interface{}]string      // MapAnyStr is alias of frequently-used map type map[interface{}]string.

  17.     MapStrBool = map[string]bool             // MapStrBool is alias of frequently-used map type map[string]bool.
  18.     MapIntBool = map[int]bool                // MapIntBool is alias of frequently-used map type map[int]bool.
  19. )
  21. type (
  23.     ListAnyAny  = []MapAnyAny  // ListAnyAny is alias of frequently-used slice type []MapAnyAny.
  24.     ListAnyStr  = []MapAnyStr  // ListAnyStr is alias of frequently-used slice type []MapAnyStr.
  25.     ListAnyInt  = []MapAnyInt  // ListAnyInt is alias of frequently-used slice type []MapAnyInt.
  26.     ListStrAny  = []MapStrAny  // ListStrAny is alias of frequently-used slice type []MapStrAny.
  27.     ListStrStr  = []MapStrStr  // ListStrStr is alias of frequently-used slice type []MapStrStr.
  28.     ListStrInt  = []MapStrInt  // ListStrInt is alias of frequently-used slice type []MapStrInt.
  29.     ListIntAny  = []MapIntAny  // ListIntAny is alias of frequently-used slice type []MapIntAny.
  30.     ListIntStr  = []MapIntStr  // ListIntStr is alias of frequently-used slice type []MapIntStr.
  31.     ListIntInt  = []MapIntInt  // ListIntInt is alias of frequently-used slice type []MapIntInt.
  32.     ListAnyBool = []MapAnyBool // ListAnyBool is alias of frequently-used slice type []MapAnyBool.

  34.     ListIntBool = []MapIntBool // ListIntBool is alias of frequently-used slice type []MapIntBool.
  35. )
  36. type (

常用对象

常用对象往往通过单例模式进行管理，可以根据不同的单例名称获取对应的对象实例，并在对象初始化时会自动检索获取配置文件中的对应配置项，具体配置项请查看对应对象的章节介绍。

  1. func Client() *ghttp.Client

创建一个新的客户端对象。

Validator校验对象

  1. func Validator() *gvalid.Validator

创建一个新的数据校验对象。

(单例) 配置管理对象

  1. func Cfg(name ...string) *gcfg.Config

该单例对象将会自动按照文件后缀toml/yaml/yml/json/ini/xml文自动检索配置文件。默认情况下会自动检索配置文件config.toml/config.yaml/config.yml/config.json/config.ini/config.xml并缓存，配置文件在外部被修改时将会自动刷新缓存。

为方便多文件场景下的配置文件调用，简便使用并提高开发效率，单例对象在创建时将会自动使用单例名称进行文件检索。例如：g.Cfg("redis")获取到的单例对象将默认会自动检索redis.toml/redis.yaml/redis.yml/redis.json/redis.ini/redis.xml，如果检索成功那么将该文件加载到内存缓存中，下一次将会直接从内存中读取；当该文件不存在时，则使用默认的配置文件（config.toml）。

(单例) 日志管理对象

  1. func View(name ...string) *gview.View

该单例对象将会自动读取默认配置文件中的viewer配置项，并只会初始化一次模板引擎对象。内部采用了懒初始化设计，获取模板引擎对象时只是创建了一个轻量的模板管理对象，只有当解析模板文件时才会真正初始化。

(单例) WEB Server

  1. func Server(name ...interface{}) *ghttp.Server

该单例对象将会自动读取默认配置文件中的server配置项，并只会初始化一次Server对象。

(单例) TCP Server

  1. func TcpServer(name ...interface{}) *gtcp.Server

(单例) UDP Server

  1. func UdpServer(name ...interface{}) *gudp.Server

该单例对象将会自动读取默认配置文件中的database配置项，并只会初始化一次DB对象。

此外，可以通过以下方法在默认数据库上创建一个Model对象：

  1. func Model(tables string, db ...string) *gdb.Model

(单例) Redis客户端对象

  1. func Redis(name ...string) *gredis.Redis

(单例) 资源管理对象

  1. func Res(name ...string) *gres.Resource

(单例) 国际化管理对象

  1. func I18n(name ...string) *gi18n.Manager
