此方法将路径作为输入并测试用户的权限。...让我们看下面的示例,该示例使用fs.access()检查给定目录是否存在: const fs = require('fs'); // directory to check if exists const...'does not exist' : 'exists'}`); }); 查看本指南,以了解有关在Node.js应用程序中读写文件的更多信息。

check: setImmediate() 的回调会在这个阶段执⾏。 close callbacks: 例如 socket.on('close', ...) 这种close事件的回调。 Event Loop 从任务队列获取任务,然后将任务添加到执⾏栈中( 动态,根据函数调⽤),JavaScript 引擎获取执⾏栈最顶层元素(即正在运⾏的执⾏上下⽂)进⾏运⾏!
