从上至下逻辑
检测是否存在AMD loder
检测是否存在requirejs接口
检测是否存在require配置对象- req.config 支持require.config协作其他AMD加载器
- req.nextTick 定时执行
- 如果不存在require对象，赋值req
- req.version 版本
- req.jsExtRegExp
- req.isBrowser
- req.s
- req({}) 创建默认上下文
- 给全局req对象导入一些人性化方法
- 如果是浏览器环境，赋值s.head为head容器
- req.onError
- req.createNode
- req.load
- 设定base路径
- req.exec
定义define
定义define.amd
加载完所需module后加载config.js执行require.config()?
normalize–>name2url–>enable–>check–>fetch–>module.load–>context.load–>req.load最后加载map.url
