javascript - glob-fs glob.readdirSync 的意外行为

Question

我有以下nodejs代码。客户端首先调用/api/demosounds，然后调用/api/testsounds。

var glob = require('glob-fs')({ gitignore: true });
app.get('/api/demosounds',function(req,res){
        var demosounds = []
        var demosoundlist = glob.readdirSync('src/assets/demosounds/*.wav');
        demosounds = demosounds.concat(demosoundlist)
        for (var i = 0; i < demosounds.length; i++) {
           demosounds[i] =  demosounds[i].replace("src/assets/","/api/static/")
        }
        demosounds = demosounds.sort()
        res.json(demosounds)
        })

app.get('/api/testsounds',function(req,res){
    var listofsounds = []
    var folderlist = ['01_sinus','02_pulse_train','03_contour_le','04_contour_fel','05_variable','06_complex_le','07_complex_fel']

    for (var x = 0; x < folderlist.length; x++){
          var testsoundlist = glob.readdirSync('src/assets/' + folderlist[x] +'/*.wav');

          listofsounds = listofsounds.concat(testsoundlist)
    }

在执行 glob.readdirSync('src/assets/01_sinus/*.wav') 时，我希望仅获得以 src/assets/01_sinus/ 开头的路径然而 testsoundlist 的开头如下:

[ 'src/assets/demosounds/electricity.wav',
  'src/assets/demosounds/phone.wav',
  'src/assets/demosounds/water.wav',
  'src/assets/demosounds/wind.wav',
  'src/assets/01_sinus/02_sin1_0065_0.16923076923076924.wav',
  'src/assets/01_sinus/04_sin1_0065_0.7692307692307693.wav',
  'src/assets/01_sinus/05_sin1_0065_1.0615384615384615.wav',
  'src/assets/01_sinus/07_sin1_0165_0.07272727272727272.wav',

我不知道为什么会发生这种情况:(

更新

下面的代码更接近问题

var glob = require('glob-fs')({ gitignore: true });
var folderlist = ['01_sinus','02_pulse_train','03_contour_le','04_contour_fel','05_variable','06_complex_le','07_complex_fel']
for (var x = 0; x < folderlist.length; x++){
          console.log((glob.readdirSync('src/assets/' + folderlist[x] +'/*.wav').length))
      }

输出这个，就好像glob会记住之前的glob一样。

图书馆似乎不再维护了，有一个挂issue有着完全相同的问题，所以看起来这是一个错误。

解决方案是简单地使用 glob ，在本例中是glob.sync()。
