node.js中的fs.readdir方法使用说明

fs.readdir(path, [callback(err,files)])

var fs = require('fs');
fs.readdir('readdirtest', function(err,files){
 if(err){
  console.log(err);
 }
 console.log(files);
})

fs.readdir = function(path, callback) {
  callback = makeCallback(callback);
  if (!nullCheck(path, callback)) return;
  binding.readdir(pathModule._makeLong(path), callback);
};
